for 37,681 miles ^^

THOSE beautiful, wide, straight, smooth roads you've been 
wishing for, are really on their way. The magnificent plan of 
interstate iiighways, greatest road program m U. S. history, is 
already taking form at the rate of 700 million dollars worth of con- 
struction per jear. 

37,681 miles of swell driving , . . direct travel from any part of 
the country to any other part . . . routes north and south, east and 
west, and diagonal routes as well . . . big highways directly serving 
practically all cities of 50,000 population or more . . . 

This is part of the better America that our generation is build- 
ing. It's taking plenty of brains. Plenty of manpower. Lots of 
cement. And lots of steel. 

United States Steel has always played an Important part in 
buildmg the nation's highways. We've supplied steel reinforcing 
bars and wire fabric to make roads stronger, smoother, longer-last- 
ing. We've made the steel for road-building machinery, the steel 
pipe and culverts for proper drainage. We've built bridges to 
carry highways over rivers and canyons. We've furnished steel and 
cement to help drill highway tunnels. 

United States Steel is ready to help with any job the nation 
has in the building of a better America. That's one reason why 
United States Steel is a good place to work.

'Well, Ted, that's one way to put it ! 
And this sure is the same Roebling. 
Besides making wire and huge 
cables for suspension bridges, 
Roebling weaves wire screens. I've 
seen screens like this in quarries and

Roebling plants in and near Trenton, New 
Jersey, developments are made constantly 
that bring new efficiency and economy to 
a vast range of industrial operations. 



WIRE nOPE. Roebling wire rope is 
made in a large range of types to assure 
lopflight performance in every application.

Automatic Flight Recorder 

A new t\pc lit tliiilir rcconici-, which 
automatically records air roughness, alti-

L'se cil flifzht recorders will prtivide 
coniiiiercial airlines increased iiiloriiia- 
tion on their flight operations, and make 
possible greater operational control. 

The actual record is made by a stylus, 
which scratches through a thin coating 
on a slowly-moving strip of paper and 
leaves a black tiace. 

The flight recorder, which makes .-i 
record of flight data from take-ott to 
landing, is so accurate in measuring alti- 
tude that it indicates changes as small 
as ten feet. 

Rocket Power 

Impdit.int rise.irch on h\dra/ine, the 
fuel of the future, is being done here 
by five scientists under the direction ot 
Prof. Ludwig F. .'\udrieth of the 
chemistry department. 

Hydrazine, A'.,//.,, is a water - clear 



liqiu'd. A derivative of ammonia, it 
burns completely to nitrogen and water 
\apor. These lightweight molecules are 
especially effective for pushing rockets 
in rarefied air or in outer space. With 
hydrogen peroxide supplying oxygen for 
combustion, hydrazine was used by the 
(lermans as fuel for their wartime 
idckets. 

The research promises to hasten the 
day of spaceships by reducing the pric' 
from four dollars to two-bits a pound.

Mind and Matter 

According to a recent article about 
servomechanisms in the Martin Star, 
"physiologists have recently shown cer- 
t.un interrelations of nerve cells of the 
brain to be quite similar to links in elec- 
tro-mechanical systems. Thus, thought 
processes or their equivalent can, in a 
limited wa\, of course, now be ap- 
[iroached in the laboratory. It is quite 
possible, for example, to design a ma- 
chine to play chess, to choose between 
winning mo\es and losing moves, to ac- 
cumulate experiences by continuous play- 
ing, and thus to become a far better 
player than the man who designs it! 

". . . While we can now at a cost of 
a few thousand dollars duplicate the 
function of a single brain nerve cell, the 
human brain has many billions of these 
cells, whose function would have to be 
iluplicated, built and operated together 
to match its almost infinite choice of 
possible decisions." 

What if two electro-mechanical chess 
players were to play a few friendly 
games ?

SLIPSTICK SHUFFLING 

Ufi Hill Stulfrstruni. I'pr.K. 'S2 



This article will deal priniarih with 
the scales on the polyphase duplex slide- 
rule rather than the simple Mannheim 
rule. It will be taken for granted that 
most engineers already know how to 
perform multiplication and di\ision on 
this t\pe of rule. 

For the novice, howe\er. it can be 
pointed out that all numbers on the 
C and D scales are in direct proportion. 
With the C index aligned with an\ 
number, ii, on the D scale, any number, 
//, on the (J scale is in the ratio of 1 : ii 
witii the number, r, opposite it on the /) 
scale. Ihe proportion, 1 : a ^ /> : i\ is 
thus represented. By algebra, this can 
be transformed to /i// = c, giving us the 
principle in\oI\ed in multiplication. 
Likewise, a = r h which is the principle 
in\olved in division. 

CI. Til,- Invnt,d C Saili- 
\ he (J scale is exactly the same as 
the C scale except that the CI scale 
reads from right to left whereas the C 
scale reads from left to right. With the 
indexes of the (] and ('>'/ scales aligned, 
all numbers which are opposite each 
other are reciprocals. When performing 
multiplication and division with the CJ 
and D scales, the processes are reversed. 
This is very useful in finding factors of 
an\ number. Set the index of the (U 
scale at the given number on D. Any 
two numbers on (U and /) which fall 
opposite each other are factois of the 
given number. 

Sqiliircs mil! Sfjii/irc Ranis 

The squares of numbers on the C' and 
/) scales lie opposite these numbers on 
the J and B scales. Likewise, the square 
roots of numbers on the A and B scales 
lie opposite these numbers on the (j and 
D scales. Some confusion is encountered 
here, however, when trying to place the 
decimal point. 

We shall call the left half of the A 
scale A^ and the right half A ^ for sim- 
plification. -■/, may represent 1 to 10, 
and A., 10 to I'OO; or A,, 100 to 
lIKKt, and A,, 1000 to 10000, etc. Like- 
wise, ./, may represent 1 to .1, and A .„ 
.1 to .01 ; or A, mav represent .01 to 
.001, and A,, .001 to .0001, etc. 

Squares of numbers on D may be read 
directly from A and the decimal point 
placed by inspection. 

When finding the square roots of 
numbers greater than one, begin at the 
decimal point and mark off the integers 
in groups of two proceeding to the left. 
If the last group contains one figure, 



use ./,. If it contains two, use A .^. When 
finding the square roots of decimal frac- 
tions, proceed to the right of the decimal 
point marking off the integers in groups 
of two. If the first group that contain;- 
integers other than ciphers contains one 
figure, use .V,. If it contains two, use 
./ .. In either case the square root con- 



This article explains some of the 
less familiar uses of the slide-rule 
that may be valuable timesavers. 
It is assumed that the reader is 
familiar with fundamental uses, 
but hoped that a couple new tricks 
may add to the speed of operation. 



tain> the same number of integers as 
the n u m b e r of groups in the gi\en 
number. 

Multiplication and division can be 
performed on A and B as well as C>' and 
D. but greater accuracy is obtained from 
the Cj and D scales. The A and B scales 
can be used with the 6' and D scales 
in problems involving squares and roots, 
such as, irh = c d'- and \l ah = c d. 

(juhis and (hihe Roots 

The cubes of numbers on the D scale 
are found on the K scale, and the cube 
roots of numbers on A' are found on D. 
For simplicit\, we shall call the left 
section of A', A'^, the center section, K.,, 
and the right section A'.,. 

A',. A'„, and A'., mav represent 1 to 10, 
10 to 10(), and 100 to 1000 respectivelv, 
or 1000 to 1()000, 10000 to 100000, 
and 100000 to 1000000, etc. Likewise 
they may represent 1 to .1, .1 to .01, 
and .01 to .001 respectivelv, or .001 to 
.0001, .0001 to .00001. and .00001 to 
.000001, etc. 

For numbers greater than one, begin 
at the decimal point and mark off the 
numbers into groups of three figures 
proceeding toward the left. If the last 
group contains one, two, or three fig- 
ures, use A,, A.,, or A. J respectively. 

If the cube of a nimiber is found on 
A], A.,, A.,, to find the number of fig- 
ures of the cube, multiply the number 
of figures in the given number by three 
and subtract two, one, none respectively. 

If the cube root of a number is found 
from A',. A',, A'.;, to find the number of 
figures of the root, add two, one, none 
respectively to the number of figures in 
the given numhi-r and di\ide by three. 



The A scale may be useil with the C 
scale in problems involving multiplica- 
tion and division of numbers with cubes 
or cube roots of lumibers. Combinations 
of operations with the A', A, B, C, and 
D scales can solve problems involving 
such exponents as 3, 4, 5, 6, etc., 5/3, 
4 3, 5 6, 3 9, etc. Application of the 
rules for exponents will make the opera- 
tions obvious. 

Thr Folded Sra/rs. CF. DF. (AF 

One of the most convenient scales on 
the polyphase duplex slide-rule is the 
folded scale. The folded scales are ex- 
actly the same as the C, D, and ^.V 
scales, but they have been split at r,, 
3.1416, and the indexes placed together. 

All numbers on the C and (^F scales, 
the D and DF scales, and the CI and 
CAF scales are in the ratio of 1 : ~. This 
is most useful in computing the ratio of 
the circumference of a circle with its 
diameter since (j = -d. This ratio may 
be utilizeil in nearly all operations in- 
\'olving -. 

It may be noticed that, when setting 
problems of multiplication and division 
on the C and D scales, some of the lunii- 
bers invohed run off of the scale, and 
the indexes have to be exchanged. The 
primary purpose for the folding scales 
is to avoid such inconvenience. 

In solving the problem 52 X 7-^ 13 
on the C and D scales, it will be noticed 
that such a shift of indexes is necessary. 
If. howe\er, one sets 13 on C opposite 
^2 on D. the answer can be read on DF 
opposite 7 on CF without ha\ ing to shift 
indexes. 

If the same operation is tried on the 
problem 52 yi')^^ 13, however, it will 
be foLuid that even when using the (^F 
and DF scales in this manner a shift 
of inilexes is required. To overcome this, 
set 13 on CF opposite 52 on DF and 
read the answer on D opposite 9 on C. 

Many other uses may be made of 
the combinations of these scales. 

Flic Lot/ Scale 

The L scale has 10 divisions equally 
spaced. By this arrangement the log- 
arithm of any number on the D scale 
can be found opposite it on the L scale 
when the indexes are aligned. 

riic Sine and Tangent Scales 

The sine of the angles which are 
found on the iS' scale can be read on the

When Patton )i.:\\v his Army I'n^l- 
iu'ci> tlircc weeks tiar to repair M 
bridges across the Rhine for his thrust 
into CKTiiiany — he got what he waiitei]. 
The last bolts on many of these bridges 
were tiglitened and tested as the first 
supply trains and trucks rolled across 
the ri\ei' on Rhine D-Day. 

Miiacle? No, just a daily occurrence 
for the engineers in the E.T.C). Hridges 
such as this, built on less than scratch 
at the rate of one and one-half a day, 
were by no means the most beautiful or 
the most lasting of structures. However, 
for the war days when strength, speed, 
and super-efficiency were the by-words, 
aesthetic design and lasting wear were, 
for the greater part, kicked out. 

After the capture of Cherbourg in 
the early summer of '44, U. S. Army 
f'ngineers began a large scale recon- 
struction program encompassing all of 
the important railroads and their bridges 
that covered the territory from Cher- 
bourg through Normandy and down t(j 
Paris. Most of these "bridges" were 
structures that were built on top of or 
over the wrecked bridges left bv the 



rctrcatnig ( lernian Arnn. Sonic ol these 
were erected from materials tound on 
location; others were constiucted of 
American .ind l'"nglisli prefabricated 
units. 

The most generally' used construction 
etpiipment was foiu' t\pes of prefabri- 
cated 15ritish - manufactured beam s. 
These consisted of the LST and HST 
types, light and heavy steel trestling 
columns that came in two weights and 
four lengths up to 12 feet and which 
were used in piers; UCRB, a kind of 
parallel-cord Pratt-truss span known as 
the Unit Construction Railroad Bridge; 
and RSJ's, rolled steel joist spans that 
\^■ere girders made b\' welding together 
two or three I-beams. These construc- 
tion units were handled in sections light 
enough for one man to carry. They 
were easily and speedily assembled at 
the site of building.

To the north, the large Albert Can.il 
in Helgium also became an imjiortant 
link i]i the supply lines. Repairs of its 
locks and broken bridges were also

r.'ited as a major engineering oper.ition. 
It was, in fact, o\er this canal th.it one 
of the most extraonlinary examples of 
the famed Hailey bridge was constructed. 
The Hailey bridge, a design of tem- 
porary structure as used by Arm\' Kn- 
gineers in the war, came in lightweight 
truss panels that were put together in 
man\ combinations serving as every- 
thing from piers and decks of bridges 
to construction trestles. 

Credit for the construction of this 
grandpop of all Baileys goes to the 
3()S.3rd Combat Battalion of the Ninth 
Army who turned it out in a new rec- 
ord of 24 hours. The bridge, a "double- 
triple" design (two tiers of three paral- 
lel trusses at either side of the roadway), 
has three span lengths of 151, 152, and 
121 feet; and both superstructure and 
52-foot high piers are composed of 5x10 
Bailey truss panels. 

Existing conditions when the Engi- 
neers moved in to begin operations were 
the 122-foot canal itself, a 10-foot tow- 
path on the east side, a 33-foot road on 
the west, and 60-foot banks with a 2:1 
slope. Construction began with the set- 
ting of timber cribbing foundations fol- 
lowed by pier erections. A cableway laid 
the first three tiers of trusses on the east 
bank, while on top of the same slope, 
the superstructure was being assembled. 
To this fabrication was then attached 
the temporary "launching nose." 

Characteristic of all Bailey bridges, 
this "nose," consisting of several lengths 
of "single-single" makeup (one tier of 
a single truss at either side of the road ) 
was light enough to be pushed over the 
bank, cantile\er style. Here it was tem- 
porarily anchored back on the bank and 
then, from its tip, block and tackle 
lou-ered the two top tiers of the east 
pier into place. Superstructure and nose 
were then cantilevered out over the 
canal to the east bank \\here the pier 
on that side had meanwhile been hoisted 
into place by a crawler crane. The span 
then continued to the top of the west 
bank. Operations were concluded with 
the lowering of the deck into its sup- 
[lorts and jacking it into place. 

Early Difficulties 

In the days that preceded the Rhine 
iinasion, supplies and materials were 
heaped in great dumps along the banks 
of the ri\er that had been cleareii of 
the retreating eneiiu. The Rhine itself

was one hiigi' iini(1dlc into which had 
fallen the ruins of e\ery bridge be-

The eastern bank of the river bristled 
with Nazi encampments; on the west- 
ern hank, the First, Third, and Ninth 
ainiies had ensconced themselves in 
formidable strength. Both forces on 
cither side of the river were, like the 
cat-and-canary parable, waiting for the 
other to make the first move. 

The break finally came and came fast. 
The site was Wesel, a little town of 
originally SO, 0(10 inhabitants, situateil 
plunk in the middle of the Rhine bat- 
tlegrounds. Previous to the Wesel cross- 
ing, an earlier bridgehead had been 
established at Remagen, where one lone 
railroad bridge was foiutd still standing 
vipon which the Engineers Corp had 
founded high hopes. This, however, 
proved a fluke when heavy German 
shell-fire fatalh' se\ered the top choiil 
of the thiee-span tied-arch design. \'i- 
brations set up by gales of wind caused 
buckling and deflections that at last 
finished off the structure. 

Across at If cscl 
Wesel was the only rea;onablc path 
across the Rhine. At the cities ol 
Cologne, Dusseldorf, and Duisbmg, the 
river-bed was glutted with rubbish ot 
their world-famous bridges. South ot 
Coblenz, the river swept through iioiin-, 
and between cliffs that were ill-Miitcil 
for only temporary structures. Tliot' 
mountainous districts w e r e replaced 
further to the north by a widening 
river s\\ee|iing into fertile farmland and 



deep gia\el beds. This, however, was 
tco far down the river for the sake of 
con\enience. 

American forces opened the siege at 
Wesel on the night of March 22, 1945, 
with 3,000 bombers kicking up the dust 
around German fortifications on the 
east bank. The next night, the artillery 
shredded up what was left and the fol- 
lowing morning found both engineers 
and troops on the captured banks. 

Once oxer the river, the infantry 
fanned out and advanced several miles 
inland to eliminate all possibility of 
enemy fire while the bridge-building was 
in progress. Right on schedule, floating 
temporary bridges including a treadwa\ , 
a heavy pontoon, and a floating Bailey, 
spanned the river 50 hours after the 
opening assault. In addition, crews had 
already begun work on the now-famous 
Wesel railroad bridge. The 2,215-foot 
bridge, completed in 10 days, was almost 
entirely prefabricated and consisted of 
LST piers set on timber pile founda- 
tions and a deck of 75-meter spans with 
deck sway bracing of timber spreaders 
and steel yokes. 

This arrangement of deck swa\ brac- 
ing was a design detail frequently em- 
|iloyed in these temporary bridging 
operations to eliminate the time-taking 
element of welding of the diaphragms 
and sway bracing to the bridge girders. 
Work on this bridge was sometimes 
carried on in as high as 15 different lo- 
cations along its course. 

And so, it was just 15 days after the 
crossing of the Rhine that the first train 
rolled across the river taking supplies 
to the advancing army spearhead. 



With the subsequent in\asiiin and 
capture of the Fatherland came the task 
of repairing the railroad and highway 
bridges that would make possible the 
lifeline supply of food for vanquished 
and for conquerors. Particularly inter- 
esting were the repairs of the (jerman 
"autobahn" (superhighway) bridges. 

Suspension bridges on the autobahns 
were, of course, completely ruined and 
only their piers could serve as the base 
for new river crossings. Steel bridges, 
it was found, were easily destroyed but 
were as easily repaired if no parts were 
missing. Truss and plate-girder bridges 
were simply repaired providing the dam- 
age had not resulted in excessive twist- 
ing. If sections had fallen down, they 
were hoisted back into place and re- 
placed on temporary supports, which, in 
some cases, amounted to no more than 
a new set of bearings. 

One of the biggest problems encoun- 
tered was the masonry and plain con- 
crete bridges that had been a favorite 
design with the German engineers in 
the absence of steel diverted into arma- 
ment channels. Without steel reinforc- 
ing, many a multiple-arch bridge was 
ruined e\en though only one arch had 
been destroyed. 

Such structures were designed so that 
the horizontal thrust from one of the 
arches was supposed to eliminate the 
equal but opposite horizontal force from 
another arch, the whole bridge then only 
subjecting its piers to vertical loads. 
With one gap in an arch, the horizon- 
tal thrusts from the other arches ac- 
cumulated in the end piers of the gap, 
thus weakening them considerably.

\n 1937, after 56 years in the Smith- 
sonian Institute, Alexander (irahani 
Hell's first practical model of a record- 
ing: machine was removed from its niclu-. 
dusted off, and the orij;inai cylindrical 
wax record played back. When this 
irranddaddy of all record players was 
cranked up it spoke approximately thus: 

"The followinfi words and soujkK air 
recordetl upon the c \ I i n d e r of the 
'( Iramophone.' . . . Tlu-re are more 
things in heaven and earth, Horatio, 
than are dreamed of in our philosophy. 
... I am a gramophone and my mother 
was a phonograph." 

Now its greatl\ modified offspring, 
the modern phonograph, is as standard 
a piece of equipment in the average 
American home as the radio, the tele- 
phone, and the family car; it is just 
.mother of the commonplace marvels of 
our technology that the world's music, 
past and present, can be brought into 
our homes under our personal control. 

There are three basic units utilized 
in the recording and reproduction of 
sound ; they are ( 1 ) .a device for the 
transformation of mechanical vibration 
into varying electric voltages (the micro- 
phone in recording and the pickup in 
playback); (2) amplifiers usually in- 
\()l\ing vacuum tubes and associated 
apparatus to build up the tiny amounts 
of power generated bv the microphone 
or pickup; (3) a device for the trans- 
formation of the electrical power furn- 
ished by the amplifier back to mechani- 
cal vibration (the cutter in recording 
and the loudspeaker in reproduction). 

Kxcept in the case of home recording 
enthusiasts the engraving of the sound 
track on records is out of the hands of 
the listener; but in most commercial 
iccords the qua!it\' of the recording is 




This sine wave was photographed 
from an oscilloscope. It is actually 
a picture of familiar 60-cycle hum. 



such that the phonograph on which the 
record is played is the limiting factor 
in the qu.ility of the resulting sound. 

To understand the process one must 
first have some idea of the character of 
sound waves, particularly those pro- 
duced by musical instnunents and the 
luinian voice. The student of phvsics 
knows that s<iuiul consists of so-called 
longitudinal waves in air or other trans- 
mitting media. Sound causes alternate 
compression and raref raction of the air ; 
if the ear drum, or the diaphragm of a 
microphone, is in the path of a soimd 
wave, it will vibrate in time with the 
frequency of the sound wave. A "pure" 
sound wave causes the air to compress 
and decompress smoothly according to 
a mathematical curve (a sine curve, 
formula: y ^ A sin Ml). 

For instance, a sound wave of 4411 
cycles per second (A above middle ('. 
on the piano) causes the air at any given 
point to compress, return to normal, be- 
come rarefied, and again return to nor- 
mal 440 times per second. However, 
most sound waves do not rise and fall 
smoothly, according to the sine curve; 
all soiuid waves of the same basic fre- 
quency repeat themselves at the same 
time interval, but the graph of intensity 
of air compression with time is a highly 
irregular curve. 

W-t even the most complicated wave 
can be broken down into components 
such that each one consists of a sine 
wave, which is usually an integral mul- 
tiple of the basic frequency of the soiuid 
wave (at least in musical tones). These 
individual sound sine waves, of the 
proper amplitude and frequency, when 
added vectorially, "give the original 
soiuid wave. These components are 
called harmonics bv the sound man, and 
overtones by the musician. They give 
(|ualit\ or timbre to the sound, and aie 
the leason for the difference in sounil 
of different musical instruments and 
voices, even when each produces a sound 
of the same basic frequency. 

The human ear can hear sounil waves 
of frequencies between roughly 31) and 
18,000 cycles per second; ;is a person 
ages, the ability to hear very high- 
pitched sounds decreases so that the 
upper limit of hearing may come down 
to 10,000 cycles or lower. Below about 
30 cycles each individual pvdse can be 
"felt" rather than heard; a machine gun 



firing 1,200 rounds a minute (2(1 per 
.second ) produces not a tone, but a series 
of individual pulses which can be felt 
more or less individually. The piano 
produces sound waves of frequencies 
ranging from 27^. cycles per second 
(the lowest note) to 4096 cycles (the 
highest). However, even the lowest note 
produces harmonics with frequencies of 
manv thousands of cycles; electronic ap- 
paratus could probably detect a trace of 
the 100th harmonic (2750 c.p.s.). 

The voice produces sound of basic 
frequencies fiom 100 to 1000 cycles 
per .second, and is very rich in overtones, 
some of which extend to HOOO cycles ; 
vowel sounds have the least harmonics 
(the letter u pronounced "oo" comes 
fairly close to being a pure sine wave), 
while the consonants can hardly be said 
to have .1 basic frequency. They are im- 
pulses rich in harmonics. Whistling pro- 
duces a practically pure high frequency 
sine wave of soimd. 

It is evident that any device intended 
to transmit sound faithfully must, among 
other things, be able to transmit equally 
well sound waves (or their correspond- 
ing electrical waves) of frequencies from 
30 to 18,000 c.p.s. Imagine a musical 
tone of, perhaps, 300 cycles, with over- 
tones up to 3000 ; each overtone has an 
intensity which is a certain definite per- 
centage of the basic tone. If, in trans- 
mitting this composite tone, some of the 
harmonics were diminished, the result- 
ing soimd would be boomy and throaty 
compared to the original tone; if the 
overtones were increased in intensity, in 
proportion to the basic, the result would 
sound tinnv. 




The complex sound wove above is 
the graph of two cycles of a saxo- 
phone note — low "C" on an alto 
horn.

THE TECHNOGRAPH 



Ho\ve\er, if the device is only intend- 
ed to transmit speech, the ohject being 
understandability and not beauty of the 
sound carried ( as in the telephone or 
aircraft radio) the transmission of fre- 
iiuencies from 200 to 2000 or 3000 
c\ cles is enough ; anything beyond con- 
tributes to naturahiess but not conipre- 
lu'nsion. 

In the recording of sound, a micro- 
phone picks up sound waves and changes 
them to corresponding voltages. These 
voltages are increased by amplifiers and 
fed to a cutting head which changes the 
\arving currents to mechanical motion 
of a cutting stylus set into the head. 
This stylus, like a tiny chisel, carves a 
V-shaped groove which spirals toward 
the center from the outside in the sur- 
face of a plastic coated record ; most 
commercial records (not the long- 
playing variety) are cut about 88 
grooves per inch, radially. 

The cutter stylus vibrates in time 
with the sound waves picked up by the 
microphone, and the groove which nor- 
iT.allv is a smooth spiral becomes a wa\\ 
trace. This trace, magnified, would ap- 
pear as a miiu'ature graph of the varia- 
tion of ail' pressure with time, or a 
graph of the sound wave. Commercial 
discs are molded from a metal "nega- 
ti\e" made from the original "master," 
which is never played. 

When the record is played back a 
needle is set into the groove ; as the rec- 
ord spins, the needle follows the groove 
and is mechanically forced to vibrate 
fi'om side to side. The needle may be 
mounted in one of several devices de- 
signed to change this mechanical vibra- 
tion into electrical voltages. These 
\oltages are proportional to the displace- 
ment of the needle in crystal cartridges, 
and to the side-to-side velocity in mag- 
netic units. 

The most popular cartridges use a 
piezo-electrical salt crystal with proper- 
ties such that a mechanical twisting or 
bending of the crystal causes a voltage 
to appear between the contacts on op- 
posite faces of the crystal. If the modu- 
lated groove causes the needle to vibrate 
440 times per second, the crystal pro- 
duces an alternating voltage of 440 
c.p.s. ; if the tone engraved in the groove 
lias 75 assorted overtones, the crystal 
produces 75 harmonics; if the needle 
\ibrates twice as far at one time as an- 
other, the crystal produces twice the \ol- 
tage. 

A typical crystal will produce about 
one volt between its opposite faces. 
However, the current which can be 
drawn from it is so small that the elec- 
trical power produced is on the order 
of a few millionths of a watt. This is 
barely enough to be audible in a pair of 
headphones. To build this up to a value 
large enough to operate a loudspeaker, 
\ncinim tube amplifiers are used. 



The action of amplifiers is too com- 
plicated to be discussed here; their 
operation can be compared to a \al\e 
in a water pipe. Just as a small force 
on the valve handle will control large 
amounts of water under high pressure, 
a small voltage on the grid of a vacuum 
tube will control relatively large cur- 
rents in the plate circuit and cause 
large variations of voltage there. An al- 
ternating voltage of one volt applied to 
the grid of a typical triode vacuum tube 
might cause an alternating voltage on 
the plate of 60 volts — an amplification 
of 60 times. Certain tubes can be nnde 
to amplify as much as 350 times. Where

cutter vibrating under modulation

graph. The bright spots are high- 
lights from irregularities in the 
bottom of the grooves. 

greater amplification is necessary, sev- 
eral tubes are connected in "cascade" 
so that the output of one is fed into 
the input of the next, and the individual 
gains are multiplied. By this system care- 
fully designed amplifiers can be built 
which will amplify several hundred 
thousand times. 

Special power-hanilling tubes are used 
as the final or output tubes in ampli- 
fiers; their gain is low (about 10 times), 
but fairly large currents can be drawn 
from them so that they are capable of 
delivering several watts of power. At 
normal room volume a phonograph am- 
plifier is driving the speaker with little 
less than one watt. Two or four tubes 
can be used in special circuits ("push- 
pull" or parallel or both) for the final 
amplification stage to produce much 
larger amounts of power; some large 
public-address amplifiers are capable of 
delivering 50 to 100 watts to the 
speakers. 

Vacuum tubes are "high impedance" 
devices — the\- control rather high \ol- 
tages at low currents. On the other 
hand, a speaker is a "low impedance" 
mechanism, requiring only small \ol- 
tages but drawing large currents. There- 
fore a transformer is used to transfer 
the electrical power from the final tube 
or tubes to the speaker and at the same 
time "match" the two highly different 
units. Transformers change voltage and 
current in opposite ratios; if the ratio 



of the turns of wire is such that the 
voltage in the secondary is liahed, the 
current is doubled, and vice versa. No 
increase in power can be made in a 
transformer, but very little is lost; they 
are on the order of 08 per cent efficient, 
one of the most efficient machines ever 
invented. 

The speaker is a device for changing 
alternating currents to mechanical vibra- 
tions in air — that is, to sound waves. 
When the alternating current originally 
produced by the crystal in the tone arm 
has been suitably amplified, it is fed to 
the speaker's voice coil, which is sus- 
pended in a strong magnetic field. As 
the current changes cyclicly in the voice 
coil in time with the vibrations of the 
needle in the record groo\e, the coil is 
forced back and forth in the magnetic 
field. Since it is rigidly attached to the 
center of the cone of the speaker, th.e 
cone aLso vibrates, compressing and de- 
compressing the air, and causing sound 
waves which are more or less accurate 
replicas of the original sound recorded 
on the record. 

As one might expect, there are many 
chances for imperfect operation in the 
chain. Each separate unit which carries 
the sound, whether as actual sound 
waves or the corresponding alternating 
\oltages, must act linearly; the output 
of it must be in accurate proportion to 
the input no matter at what frequency 
or set of frequencies it is operating. 
With all the possibilities for distortion 
it seems rather remarkable that the 
sound froni an amplifier's speaker is so 
much like that of the original. Consider 
the fact that the paper cone of a i^^.OO 
speaker driven by possibly four little 
tubes must attempt to set up sound 
wa\es corresponding to those producetl 
by perhaps J! 10,000 worth of instruments 
of a 75-piece symphony orchestra. 

Amplifiers themselves can be designed 
with very small distortion; they can be, 
but often aren't. IVIost of the "ampli- 
tude distortion," or departure from strict 
proportionality, of amplifiers occms in 
the final or output tube; and in man\' 
small amplifiers such as are used in 
radios and phonographs the distortion 
runs as high as 12 or 15 per cent. In 
the better quality amplifiers it is around 
5 or as low as 2 per cent. 

Also important, as mentioned before, 
is the ability to amplify equally' all fre- 
quencies o\er a \\'ide range. Since the 
tubes used in ordinary amplifiers will 
work quite well at frequencies as high 
as 20 million cycles per second (and as 
low as zero, or direct cinrent), and 
since circuits almost like the ones in 
phonographs can be made to work from 
below 20 c.p.s. up to 2 or 3 million 
c.p.s., it is obvious that little trouble 
should be experienced in making them 
operate to only 18,000 cycles.

Ill recent years, graduates of tlic en- 
gineering colleges have enjoyed the .id- 
\antage ot a great demand for their 
services. In all branches of engineering, 
the graduate has been able to choose al- 
most at will the type of work, locality, 
and eniplo\er which he desires. 

Hut the shortage of engineers which 
has fostered this situation is becoming 
satisfied in many fields. Recent surveys 
indicate an actual or impending surplus 
of engineers in main' fields. As a result, 
graduate engineers must again consider 
the possibility of having a difficult time 
to find satisfactory employment. This 
is especially true in the fields of engi- 
neering which have been popularized 
during the war, and in which men were 
trained by the services. 

The men who are freshmen and soph- 
omores in engineering schools now need 
to consider the advice of men such as 
Karl Compton, president of Massachu- 
setts Institute of Technology, who has 
ad\ised college men to enter the fields 
of mining, metalhu'gy and ceramics, to 
ensure that adequate opportunities will 
be available for employment after grad- 
uation. 

In this article, some attempt \v\\l be 
made to e\plam the field of nictalluigi- 



cal engineering to those first and second 
\c,ir engineering students who have not 
alreadj' decided their particular field of 
specialization. It has become apparent 
that many young men on the campus 
ha\e little or no idea of what metal- 
lurgical engineers do, that a complete 
curriculum in metallurgical engineering 
is offered at the University of Illinois, 
or that this department enjoys the repu- 
tation of being one of the finest in the 
nation. Employers from all over the 
countr\' have declared their satisfaction 
with the training of men graduated from 
the University of Illinois. 

The facilities of the department at 
the University include the Metallurgy- 
laboratory, and offices and classrooms 
in the Ceramics building. The Metal- 
lurgy laboratory is a two-story building 
located between the Transportation and 
Ceramics buildings, and houses a ma- 
chine shop, offices and classroom, and 
laboratories for welding, electrometal- 
lurgy, heat treatment, casting, ir.etal- 
lography, and research. 

Opportunity Plus 

The enrollment in metallurgical engi- 
neering all over the country is very low 
in comparison to the demand for metal- 
lurgists. This is apparently due to a lack 




(if understanding ni the field by main 
students. Hence, in spite of the great in- 
crease in dem;ind for metallurgists, the 
enrollment of this department is now 
about e<iu;il to the prewar enrollment, 
while some othei' dep.-utineiits base dou- 
bled and tripled their prewar enroll- 
ments. 

As a consequence of this fact, main 
more job opportunities exist than there 
are graduates to fill them. As an ex- 




IlllfSi 




Students examine specimens in the metallography laboratory of the 
University of Illinois' well equipped Metallurgy Department. 



These control boards operate the 
furnaces in the heat treatment 
laboratory. 

ample, the graduates of the department 
continue to enjoy a large selection of 
employment offers. Industry assures us 
that there is no foreseeable end to this 
under-saturation in the light of present 
enrollments. Figures released by indus- 
try show that the starting salary re- 
cei\-ed by metallurgists is greater than 
that of any other fiehl except chemical 
engineering, with the same trend con- 
tinuing with increased experience. 

Metallurgy as an art has existed for 
centuries, but the science of metallurgy 
has developed within the last genera- 
tion. So it is natural that in such a new 
field, few people are familiar with the 
type of work in which the metallurgist 
is engaged. In order to permit a better 
understanding of the field, let us briefly 
describe metallurgical engineering. 

The field of metallurgical engineer- 
ing can be conveniently divided into two 
categories, process metallurgy and physi- 
cal metallurgy; although some prefer to 
further classify the latter as mechanical 
nu't.illurgy and physical metallurgy.

ENGINEERING SOCIETIES 

By Ed. Pahl, E.E. '53 

The Stuilenr Knginccniig Societies 
Council was organized about one and 
one-half semesters ago, with the pmpose 
of integrating the engineering societies' 
activities. Its first semester of active 
existence was successfully realized with 
the presentation of the St. Pat's Hall 
and with the engineers' Spring Picnic 
( it rained, but a good tmie was hail b\ 
all). 

Member societies represented m the 
F.ngineering Coiuicil are chemical engi- 
neers, electrical engineers, civil engi- 
neers, mechanical engineers, aeronautical 
engineers, and the Penaleare society. 
Each of these engineering societies sends 
its vice president and an elected repre- 
sentative to the Council meetings. At 
these meetings the activities of the vari- 
ous societies are discussed, and an effort 
is made in every case to secure coopera- 
tion of all the engineers in the execution 
of these activities. 

The Engineering Council occasion- 
ally sponsors activities, such as the St. 
Pat's Hall, which are enthusiastically 
supported by students in all of the 
school's colleges. If this coming semes- 
ter is as successful for the Council as 
was last semester, there is no doubt that 
this outstanding organization will con- 
tinue to ser\e the students of Na\\' Pier. 
A.I. E.E. 

The A.I.K.K. is cordially in\iting all 
electrical engineering students to its first 
meeting of the semester on (October 3, 
l^H"!, at .■!:()() p. m. There will be a 
movie on the L,ijf of Thoinas E/lisoii. 
followed by a short meeting to start 
planning the semester's activities. 

The activities will include inspection 
tours of different electrical plants 
throughout Chicago, and inspiring lec- 
tures on the professional and technical 
sides of electrical engineering. 

The A.I.K.E. was organized for the 
purpose of the advancement anil dis- 
semination of the knowledge of the 
theory and practice of electrical engi- 
neering, the presentation of a proper 
perspective of engineering work, and the 
opportunity to become acquainted with 
the personnel and activities of the Amer- 
ican Institute of Electrical Engineers. 
A.S.C.E. 

The A.S.C.E. will elect its new of- 
ficers in the fall. The outgoing presi- 
dent, Mr. Frank Koepke, will call the 
first meeting in October, when officers 
will be elected for 1949-50. 



The society urges you to join as soon 
as po.ssible so that you may take ail- 
vantage of its activities. It offers a 
scholarship to one of its members for 
which all members are eligible. 

The society is planning to have its 
meetings once a month as in the past. A 
number of prominent engineers have 
promised to be speakers, and it shoidd 
have several good and interesting meet- 
ings. 

The American Society of Civil Engi- 
neers, Illinois section, is also going to 
ejitertain the stuilents at a meeting simi- 
lar to the one held last \ear. The meet- 
ing will be held at I.I.T. in November.

PIER PERSONALITIES 

By Oleg Terichow, Met.E. '51 

One of the better known educators, 
whom e\ery engineer at the Pier even- 
tually meets, is J. S. Kozacka, associate 
professor of mechanical engineering and 
head of the department of shop labora- 
tories. 

Professor Kozacka is not only well 



known at the University, but is a leader 
in various engineering organizations and 
civic groups in the Chicago area as well. 
His combineil rich store of practical ex- 
perience a n il theoretical knowledge 
serves as an invauable tool in his teach- 
ing to the students in the engineering 
curricula. 

Professor Kozacka was born and re- 
ceived his early education in Tarnow, 
Poland. He arrived in the United States 
in 1904, and has lived here ever since. 
He became a natmalized citizen in 
1913. 

After serving apprenticeship as ;i ma- 
chinist-toolmaker, he entered Pratt In- 
stitute in Hrooklyn, N. Y., in 1909. 
Upon graduation he was advised to 
study engineering at the University of

His first outstanding job after his 
completion of studies at Pratt Institute, 
was that of tool and die maker, and 
later as a foreman at the L nited States 
Motor company, now the Chrysler cor- 
poration. 

He entered the University of Michi- 
gan in 1912, graduating \\ith a H.S. de- 
cree in mechanical engineering in 1916. 
While at Michigan, he participated in 
the intramural sports, wrestling and 
boxing. Also, he served as an assistant 
to a professor in shop management 
cour.ses during his .senior year. 

After he graduated, he worked with 
the Packard corporation in production 
and control of materials. He went back 
to the University of Michigan after a 
few years and received his M.S. degree

ENGINEERING COUNCIL 

Tlu' I'Ji^irR'i'iinfj Council, coiiMStin;: 
of two ii'pii'scntativfs from each of rl\c 
insiiifcn'iig societies plus two delegates 
fioiii the Ttchtiot^niph. has a big job 
ahead of it this >ear. Its main task is 
to coordinate the efforts of the various 
engineering groups in all their mutual 
activities. 

The program is full of big deals. The 
largest engineering social e\ent of tin- 
year will be St. Pat's Hall, which will 
be near the ^'Great Day for the Kngi- 
neers." Participation in the all-Uiiiver- 
>it\ Career Conference has been planned. 

During th.it week, the combined 
councils of the \arious colleges will 
bring to the campus a large group of 
well known speakers, representing every 
major field of activity, to speak to the 
students in order to aid those who are 
luulecided about their life work. Each 
speaker will make a talk before a group, 
Mtd then private conferences with indi- 
\idual students will be scheduled so that 
each may gain personal considtation. 

A new item on the roster is .-ui ,ill- 
I'ngineering Open House similar to 
those held a few years ago — but bigger 
and better. 

■^'ou'll be getting all the details of 
these activities through your society 
representative, and you'll find the latest 
scoop right here in the I'iih. 

The officers of the Council are Rich- 
ard Wurzburger, president; Ray Hau- 
ser, vice president; William Campbell, 
secretary; and Harold Wilson, tre.isurer. 

I.A.S. 

At the last meeting of the spring 
semester, the following officers were 
elected by the Institute of 
f ^a^^g l Aeronautical Engineering: 
1 ^^^^ Allen M. Benson, president; 
Edward J. Cenek, vice pres- 
ident ; and \\\\m\ E. Gubbert, secretary- 
treasurer. 

There isn't too much news from tin- 
I..'\.S. at this time but if you'll check 
Cloud 3'^ over the Engineering campus 
\ou're certain to find any of the mem- 
bers eager to gi\e out all the latest 
prop wash.

that was held in conjunction with the 
October meeting. Plans arc ,ilso in the 
making for the annual b:uu|uct which 
will be held ne\t s|)ruig. 

The incumbent officers were Paul 
(in-cn, president; Harold A. Rodbro, 
\ ice iiresident; Keith Van Ness, secrc- 
t.ny: Art Van Sant, treasurer; and 
J.unes Garman, Engineering Council 
representative. ( New officers were elect- 
ed at the first meeting on September 
27.) You may get all the information 
th.-it you want from .Mr. j.imrs Leach, 
f.'iculty adviser. 

S.B.A.C.S. 

This impressive list of letters stands 
for the Student Branch of the American 
Ceramic Society. The society is just as 
impressive as its name. 

Established a few years ago to help 
the students and faculty keep in closer 
contact, the society has become very ac- 
tive. They have frequent talks about 
their profession, and the demonstrations 
accompanying these are really something 
to see. 

The plans for the coming \car 
haven't been released at this time, but 
you may be certain th.it there'll be 
plenty doing. 

Lucas E. Pfeiffenbcrger was elected 
president of the S.B.A.C.S. last spring. 
The other officers for this term .-ne: 
Stephen D. Stoddard, vice president; 
Charles K. Russell, secretary ; Ervin W. 
Schuetze, treasurer; Richard \\. Eul- 
rath, historian ; and Clifton C7. 15ergeron 
and Howard Rapp, representatives to 
the Engineering Council. 

A.I.Ch.E. 

Boasting a new building this fall are 
the chemical engineers. The new Chem- 
istry and Chemical Engi- 
neering building, officially 
named East Chemistry, is at 
the corner of Mathews and 
California and is reputed to 
uniiiue in every sense of the word. 
One of the main events of this vear for 
A.I.Ch.E. will be the dedication of this 
latest addition to the campus. 

Before winding up last year's busi- 
ness with their annual banquet ;md 
picnic (a beer bust for men only), the 
Chem. E.'s made plans to participate 
in the all-Engineering Open House to 
be held later this vear. .Also on the 





agenda are .some movies put out by 
some of the large chemical firms plus 
a talk by Dr. Bailar on job opportuni- 
ties. The fall semester was started with 
a smoker last month at which time Dr. 
Johnstone introduced the staff and wel- 
comed the boys back. 

At a meeting held last spring, Henrv 
Kahn was elected the chief unit opera- 
tor. Ciiving Hank a hand with the work 
are: John Shurtleff, vice president; 
Claude Lucchesi, secretary; Donald En- 
gelbrecht, treasurer; Robert Friedman 
and Dan Keefe, Engineering Council 
representatives. The facultv advisor for 
the A.I.Ch.E. is Dr. James W. We.st- 
vvater. 

A.I.E.E.-I.R.E. 
The dedication of the new E.E. build- 
ing last s|iring has left its mark on the 
electrical and radio engi- 
neers. The ruiiKH' making 
the rounds, not confirmed 
or denied, is that the nvw 
building was put up to 
show their arch-riv als that 
the E.E.'s could do it better. 

Along that line, the E.E.'s plan to 
continue the "friendly" get-togethers 
with that other society; these meetings 
will probablv take the form of mutual 
interest lectures and maybe another quiz 
show. Also on the agenda for the com- 
ing vear is participation in each and 
everv activitv th.it the other engineering 
groups want to h.ive. It was proposed 
that the list include football, basketball, 
bowling, and a few other manly contests 
with no holds barred. 

The seniors are trying to have the 
annual field trip re-established after a 
lapse in this activity during the war. 

.All the latest news can be obtained 
through the WATT M;':TER or the 
following officers: Charles Elet.son,

PROFESSOR EDWIN D. LUKE 

All over the enj;i nee ring campus last 
spring the student engineers took a poll 
to iletermine the most effective instruc- 
tor in the various departments. T he 
award in the Department of Mechani- 
cal Engineering went to Prof. Edwin 
D. Luke. 

Professor Luke was born in 10] S in 
Gilmer, down in the Lone Star State 
of Texas. He attended elementary 
school there and spent his high school 
days in Pyote, Texas, where he gradu- 
ated in PXi2. 

In 1933, he entered John Tarleton 
Agricultural College where he sta\ed for 
the next two years. Then, in 1933, he 
transferred to Texas A(S:^L He re- 
ceived his bachelor of science there in 
1937 in the curriculum of mechanical 
engineering. He staged on at 1 exas 
A&M until 1938 when he received his 
master's degree. 




EDWIN D. LUKE 

In September, 193S, he came to the 
I Diversity of Illinois and is jiow an as- 
sociate professor of mechanical engi- 
neering. 

Professor Luke entered the Arnn 
( hdnance department as a 1st lieuten- 
ant in June, 1941. He spent three years 
m the Hawaiian Islands, and after being 
discharged he returned to inacti\e dut> 
in February, 1946, as a lieutenant colo- 
nel of the Ordnance department. 



One of his main interests now is his 
job as a member of the Hoard of Ap- 
|i()intment of Student Membership to 
the American Ordnance Association. 
Each year a certain number of students 
are admitted and Professor Luke, with 
Dean Jordan, aids in the selection. 

Professor Luke is married and has 
one child, a son. He makes his home 
in the northwestern part of Champaign. 

O. M. SIDEBOTTOM 
When he entered high school, Mr. 
Sidebottom had no thought of going to 
college. During his senior year a repre- 
sentative of Lincoln Junior College, 
Lincoln, 111., interested him in going to 
school there. Although born and raised 
on a farm near Easton, III., he found 
he liked mathematics more than shuck- 
ing corn. He didn't think he would be 
interested in teaching and so decided to 
take engineering. 

At Lincoln he was aware of onl\' two 
fields of engineering, electrical and me- 
chanical. After trying to read a book on 
electricity he decided upon mechanical 
engineering and came to the University 
of Illinois in 1940. He graduated with 
a bachelor of science in mechanical en- 
gineering in 1942 and was asked if he 
would like to teach. He thought that it 
would be good experience. As he had 
liked the theoretical and applied me- 
chanics courses better than the mech.in- 




ical engineering courses, he decided he 
would rather teach T.A.M. 

He received his master of science in 
1943 and worked on research under Pro- 
fessor Schrader for four years. In 1947, 
he and Dimitry Morkovin published a 
bulletin, 'I'hc Effect of Nrjii-l' nifuruj 
Distrihiition of Stress an the ) ield 
Strength of Steel. He has instructed 
both full-time and part-time since then 
and is now, with Prof. H. J. Schrader 
and H. R. Wetenkamp, writing a bul- 
letin on car wheel investigation. 

His hobby is fishing; he also likes to 
play bridge and has an interest in pho- 
tograph\'. He bought his first new car, 
.in Oldsmobile, last jinie. He is unmar- 
ried. 

Mr. Sidebottom is a m e m b e r of 
A.S.M.E., Tau Beta Pi, Sigma Xi {a 
research fraternity), and Pi Mu Epsi- 
lon (a math honorary). He was voted 
a most effective instructor last spring.

RICHARD H, KANAK 

P'rom a politician in engineering to 
an engineer in politics is the bumpy 
road being traveled by Dick Kanak. 

Parth' explaining Dick's interest in 
traffic engineering is his long associa- 
tion with the problems concerning this 
field. For a year he drove daily the 
Jll-mile trek to Navy Pier from his 
home in l>erw>n. ami he now spends 
week ends dri\ing trucks around the 
Chicago area. Thus he has emphaticalh' 
I'xperienced all kinds of traffic coruli- 
tions. 

Dick has found that Professor Wiley's 
classes and the I.T.E. are quite valu- 
able in finding methods of correction. 
He has participated in tour local traffic 
surve\s (keeping out of the way of 
speeding cars, bicycles, and pedestrians).

A .Model Model 

Just inside till- swinging doors of Civil 
Kngincering hall is a glass - encased 
bridge with an interesting history. 

This display is a model of a niultiiile 
span, reinforced concrete, arch bridge 
that was built in Talbot lab main' years 
ago. The model, built by Prof. VV. W. 
W'ilson and his research assistants, was 
originally meant to be a simple example 
of the fundamental research carried on 
here. However, detail was added to 
make it a complete display. Before mov- 
ing into C.E.H., it was shown at the 
Century of Progress World's Fair in 
Chicago in 1933. 

The prototype was a reinforced con- 
crete structure consisting of three 27- 
foot spans set upon piers 20 feet high. 
The piers were built on mechanisms de- 
signed to measure the reactions of the 
abutments under varied conditions of 
load. 1 he load, consisting of a concrete 



block of known weight, was applied to 
points on the deck, and changes in re- 
actions and stresses were accurately de- 
termineil. 

In working on these tests. Prof. Wil- 
son aided the promotion of this multiple 
span type of structure, and was awarded 
the Crowe's medal by the A.S.C.E. for 
written reports of his findings.

// Happened in Thermo 

Dr. Comings, high pressure man in 
the Ch.E. department, told the follow- 
ing to his victims in thermo last spring. 

One day while making the rounds 
of his ark, Noah was taking census of 
the animals aboard. After finding 17 
rabbits, five squirrels, three giraffes, etc., 
he came upon two lonely snakes — the 
same ones he had brought aboard. 

"Why haven't you multiplied like the 
other animals on the ship?" Xoah asked. 

"We're adders," was the simple reply.

of Civil Engineering Hall. (Photo by Lou Davidson.) 



As the original B.irnum continued 
his rounds he noticed the shortage of 
furniture for his horde. After summon- 
ing his old friend, P. Hunxan, Xoah 
built some crude-lookiriL' log chairs and 
tables. 

Three days a f t e r installing them 
aboard the ark, Xoah was suddenly con- 
fronted with a family of five snakes. 
"Hut I thought you couldn't multiply!" 
he blurted. 

Happily papa snake replied, "We used 
your new log tables."

terials on his election to the vice presi- 
dency of A.S.T.M. 

New head of the E.E. dep.irtment. 
Dr. John D. Ryder, comes from Iowa 
State college with an impressive list 
of accomplishments, and a welcoming 
smile. The November Teeh will ha\e a 
few words about both. 

Although the new struct u r e at 
Mathews and California says "Chem- 
istry and Chemical Engineering" above 
its entrance, it was named "East Chem- 
istry." 

As two-fifths of the bin'lding is oc- 
cupied by the bio-chem division, and 
three-fifths by the chem engineers, there 
has been plenty of grumbling by the 
Ch.E.'s about the apparent lack of con- 
sideration.

One fine afternoon last spring, a local 
resident was shopping in a campus drug- 
store with his attention-getting two- 
\ear-old son. After selecting his items, 
the man discovered that he had left his 
wallet at home. 

After he explained his predicament to 
the cashier, a stranger nearb>- offered to 
pay the buck. Surprised at the gesture, 
the local resident asked where to repay 
the loan.

THERE ARE TWO WAYS of regarding 
the valves in any plant. Man- 
afrenient can think of the relatively 
small cost of a single valve, and dis- 
miss it as a minor, "petty cash" 
investment. Or, they can think of 
all valves in the jdant as one valve, 
as piclnrcd, by plioto-magic, in this 
pharmaceutical plant, — and see 
val\ es in proper perspective. 
THEY 1 I\D IT PAYS to take the lat- 
ter view, for in any plant, any 
huihling where fluid control is in- 
volxed, valves, collectively, are as 
important, in terms of investment 
and operating expense, as larger 



plant miits, and should be selected 
with the same sharp eye to quality

From the Tables 



W'lu'ii takmi: :i new jdh moxinfi to a ik-w 
tiiwii, i-ntcriiii; a \\^\\ schoul, or c\en ictuni- 
ins; to school, one is presented with the proh- 
Icni of adaptation to an unfamiliar cjiviron- 
nient. The method of adaptation and the 
choice of close environment are of extreme 
personal importance, but are often neglected 
in the confusion of transition. 

Especially in the change from high school 
to college is this self-adjustment necessary. 
Graduation ceremonies give one the feeling 
of elated achievement and a new sense of in- 
dependence from the past. "I'm on my own; 
I'm a MAN now!" seems to be the usual 
sensation. The training and influence of the 
home and church, being things of the past, 
are too easily left up in the attic with the 
the model airplanes and high school books. 
The thrills of life at college await! 

Except for possible financial assistance, we 
do achieve a partial independence of home in- 
fluences. We're free to think and plan how, 
and if, we want to. Nobody is going to tell 
us to winiN about right and wrong! We 
can choose our friends or "beer buddies" and 
blindly follow the lights and thrills of col- 
lege if we want to! 

Hut what is to fill the sudden \ acuum of 
love, guidance and inspiration that were, 
of times imconsciously, received at home? 
Are we to blindly grope down the maze of 
dead-end alleys of indecision, or is there some- 
thing that can lead us to a purpose? 

Choices during the first few months of a 
college career lead to habits, which, if not 
deliberately broken, may cause a whole life 
to deteriorate. 

Ho we assume the responsibility of delib- 
erate decisions regarding our purposes and 
goals to be attained here? Do we really know 
why we're here? To get a degree? To learn 



a living? To gain an "education"? To learn 
to LIV'E? 

A nudtitude of experiences may be found 
on the campus, and we should be "choosey" 
about how to make use of them. True, it's 
easier to thoughtlessly follow the crowds to 
the sensuous thrills than to be a little indi- 
vidualistic and strive for personal develop- 
ment. But the difference ten years hence is 
worth the effort now. We should decide 
NOW what kind of a life we want to live; 
and N(^W is the time to start li\ing it! 

With our technical training concentrated 
on the material world, it's so easy to forget 
that the only real worth is the eternal world. 
Religion isn't kid stuff! It isn't to be left in 
the "Jesus Loves Me" Sunday school class. 
Religion can be dynamic; it should grow; it 
is to be lived and shared! 

Here on the campus so many of us tend 
to slight our personal religious development 
e\en though the possibilities of gaining a 
genuine understanding of Man's relation to 
God and to Man are the best we'll probably 
ever know. Almost every church is repre- 
sented on the campus by able and understand- 
ing leaders who are here to serve our needs 
for religious development. 

Not only are the staff members of the 
church foundations and the Y top-notch, but 
also the students who are actively participat- 
ing. They're a grand bunch of kids with the 
same problems as everyone else on the campus, 
but the\'re finding answers in a living fellow- 
ship. Their program of religion in action is 
providing a stabilizing influence that keeps 
one on an even keel, and clear in purpose 
and direction of life. 

There's no such thing as "college life." 
There is \<tin life, and there is my lite; and 
we each ha\e to li\e our own. .And NOW is 
the time to decide how to li\e it! — R.[>.H.

Now science gives the navigator an im- 
proved "homing pigeon instinct," a way 
hv which— without checking sun or stars 
— he can head his ship directly home. 

Already thoroughly proved, Loran equip- 
ment has been simplified through RCA re- 
search and engineering, so that almost any- 
one can learn to use it in a tew minutes. Free 
of human error, readings appear directly on 
the instrument. A quick check gives position. 

Br.iin of this Loran system is a circuit 
developed at RCA Laboratories wliich splits 
seconds into millions of parts— and accurately 
measures the dillcrcncc in the time it takes 
a pair of radio signals to travel from shore 
to ship. 

Gixen this information, the navigator, hun- 
dreds of miles from shore, can dctcnninc liis 



position quickly and accurately. Loran's sim- 
plicity adapts it to every type of vessel from 
merchant ship to yacht. Manufactured by

Faith of an Engineer 



1 AM AN l\N'(;iNKKR. In iii.\- profession 1 take ilcip piidc, hut v\irli(iut 
vainglory; to it I owf solemn obligations that I am eager to fulfill. 

As an Engineer, 1 will participate in none but honest enterprises. 'l"o him that has 
engaged my services, as employer or client, I will gi\e the utmost of performance and 
fidelity. 

When needed, my skill and knowledge shall be given without reservation for the 
public good. I'roni special capacity springs the obligation to use it well in the service 
of humanity; and 1 accept the challenge that this implies. 

Jealous of the high repute of my calling, I will strive to protect the interests and 
the good name of any engineer that 1 may know to be deserving; but I will not shrink, 
should duty dictate, from disclosing the truth regarding anyone that, by unscrupulous 
act, has shown himself iniworthy of the profession. 

Since the Age of Stone, human progress has been conditioned by the genius of 
my professional forbears. By them have been rendered usable to mankind Nature's 
vast resources of material and energy. By them have been vitalized and turned to 
practical account the principles of science and the revelations of technology. Lxcept 
for this heritage of accomulated experience, my efforts would be feeble. I dedicate 
myself to the dissemination of engineering knowledge, and, especialh' to the instruction 
of younger members of my profession in all its arts and traditions. 

To my fellows I pledge, in the same full measure I ask of them, integrity and fair 
dealing, tolerance and respect, and devotion to the standards and dignity of our profes- 
sion ; with the consciousness, always, that our special expcrtness carries with it the 
obligation to serve humanity with complete sincerity.

in education. At Michigan, he had de- 
cided that he could best serve the in- 
teiests of Noimg people by becoming an 
educator. "1 believe that education, 
whether it be in a specialized field such 
as engineering or in studying the liberal 
arts, should be available to all people, 
of all races," he said on luimerous oc- 
casions. 

Upon receiving his M.S., he was ap- 
pointed an associate professor of me- 
chanical engineering and director of 
shop laboratories at Lewis Institute here 
in Chicago. With the merging of Lewis 
Institute with Armour Institute of 
Technology, he remained in the same 
capacity at that school, until lQ4.i. Dur- 
ing the war, he was in charge of the 
war training courses at I.I.T. in the 
Chicago area. 

Toward the end of the war, he le- 
entered private industry as a develop- 
ment and tool engineer at Vascoloy- 
Ramet corpcnation at Waukegan, HI. 
There he helped in the de\elopment of 
carbide cutting tools. He then came here 
to head the shop lah(natoi ies when the 
Pier branch of the l. ot I. opened in 
I 946. 

Professor Ko-zacka's achievements in 
various organizations are too numerous 



to mention in full detail here. In 1934, 
he was chairman of the local section of 
the A.S.M.E. He was instrumental in 
the formation of the junior section of 
the local Chicago A.S.M.E., and re- 
ceived two honorable recognitions from 
that society for his outstanding contri- 
bution in that field. 

He is an elected member of the Polish 
Institute of Arts and Sciences, and also 
a member of the American Society for 
Engineering Education. He is now 
working on research in the action of 
cutting tools, and had previously ex- 
changed papers and data with a pro- 
fessor at the Warsaw Polytechnic Insti- 
tute prior to the outbreak of the war. 
During the war he wrote a scries of 
articles for the Science ami Ahelinnic 
magazine on precision tools and measme- 
ments. He is co-author of a new book, 
Tune/stcn and Carbide Cutting Tools. 
which will be published soon by the 
Chicago Technical Society. 

In addition to those organizations, 
he is well known in Polish-American 
civic groups. He was married in 1016, 
to the former Wanda Klopocinski, and 
has two sons, Richard and Arthur. Dick 
has already received his degree from 
the I'niversity of Michigan in chemical 
engineering, and is now the technical 
director of a production pl.int at the 
.Monsanto Chemical companv, at Mon- 



santo, III. The younger son, Arthur, i -

sured in minutes, set the minutes gage 
point (marked ') to the number of min- 
utes on the A scale and read the sine 
on the A scale at the .S index. For the 
sine of an\' angle measured in seconds, 
set the second gage point (marked ") 
to the number of secontls on the A

The tangent for angles between 5 43' 
and 45° can be foiuid on the D scale 
opposite the angle on the T scale. The 
tangent of angles less than 5 "43' is 
equal to the sine and can be found on 
the 5 scale as described above. The 
tangent of any angle A which is between 
4v and 90' equals the reciprocal of

This completes the scales found on 
the normal polyphase duplex slide-rule. 
Many other scales arc in use, but the 
discussion of them is too lengthy to be

Rare Gases Now Available iu Quantity Offer 
Challenging Subject for Study 



Anionp tlio loast kno^^■ll of Uic eloiuonli have been tlio rare <iases — Kryi>toii and 
Xenon. Oecurrinj; in tlie ainiospliere in conccnlration of one part per million for 
Krvplon, and one part per twelve million for Xenon, tlicir very scarcity j^ave them 
the status of "scicntilic curiosities" for a long time. 

But now, these gases are available in quantity in refined, compressed form. 
As these gases assume the different role of "new" materials, their individual physi- 
cal and electrical properties are finding interesting uses. 

The increased cfTicicncy of hot cathode ( fluorescent I lights is a direct result 
of using Krypton as the gas filler. The brightest light ever made by man is pro- 
duced bv an electrical discharge through a column of Krypton . . . these lights are 
used to penetrate fog at airports. 

Xenon is replacing mercury vapor in industrial (thyratron) tubes, to avoid 
low temperature condensation troubles. It is Xenon that makes practical the 
"repeater" (gas discharge) photographic flash lamp— the low resistance and good 
spectral range of the gas both being important. In the fast-growing field of atomic 
cncrgv, the rare gases become increasingly important. The use of such gases in 
Geiger Mueller counter tubes is well familiar. 

Chemists and physicists on many types of projects will want to study the 
possible value of these gases in their fields. Others may desire to work with the 
rare gases as such, contributing to further information in this expanding subject. 
Graduate students especially may find rare gases a fascinating, challenging, and 
wide open field for doctoral thesis. 

In whatever connection, scientists who may want more information on Kryp- 
ton, Xenon, Argon, etc., are invite<l to write us fully. Please write Dept. LAP,

TRUSSES . . . 

( l^'diitinufil lioin p:ij;i' ') ) 
Such was the case witli tlu- Kaciiip- 
tflbach bridge on the supiMhighwaN be- 
tween Frankfurt and Munich. Origin- 
al l\ a plain-concrete arch bridge span- 
ning a l,2()()-to()t valley, the structure 
Has almost totalN destroyed, except tor 
tliree piers lett intact — one at tlie east- 
ern end of the bridge and two others at 
tile western enil. There also remained 
three pier stubs in the midiile of the 
\alle>' whicii became the bases for piers 
for the new highway bridge that the 
.\rm\' I'ngincers constructed. T o pre- 
\ent failure of the existing piers at the 
ends due to the accumulated luuizontal 
thrust .IS mentioned abo\e, the pier to 
the east was braced with structural steel 
piping and the two piers to the west 
were tied back and anchored with six 
steel cables of 165-ton strength each. 

A great deal of the steel truss bridge 
that w;is constructed as a semiperman- 
I'lit solution to this bridging problem 
was prelabricated from SKR trusses, 
standardized ( lerman railway bridge 
trusses that were simply attached by 
bolting. The three pier stubs in the mid- 
dle of the 672-foot span that had to be 
crossed were leveled off, capped, and 
became the bases for the rocker bents 
that carried the superstructure. The 
truss superstructure itself was assembled 



(ill tile western bank ui the \allcy and 
then was cantile\ ered out to the tirst 
rocker support m the manner of Hadev 
bridge construction. 

I'erhaps the onh components of the 
bridge that were specially manulactuied 
for it weie the top and b<ittom p.nts

designed ;md made ui a nearb\ steid null. 
.'Ml other materials and machines used 
were bits of construction eepiipment con- 
fiscated from nearby (German army sup- 
ply dumps as in the case of the SKR 
tru.sses, themselves. 

I'liui II Piffii iillits 
( )ne pioblem that presented (|uite a 
danger in the reconstruction ot this and 
other bridges was the usu.-il existence in 
each pier footing of a "blasting cham- 
ber," a niche in which was cached a 
3(K)-lb. live aerial bomb. This was a 
precaution that the (jcrmans took in 
building these autobahn bridges in pre- 
paration for the time that would see 
the retreat of the (lerman army through 
their own land. In an emergeiic\' then, 
a bridge could be easily and efficiently 
ilestro\ed by setting off a main switch 
near the location. These bombs had to 
be located and destroyed before lecon- 
stniction on a bridge could begin. Lo- 
cating them was a ticklish and hazard- 
ous job. Another unseen foe were the 
"duds," bombs dropped by Allied 



planes th.it had failed to go off. .More

wmiiing the war. .Now, in peacetime, 
these stiucturis are being replaced by

ill the production of metals \nx iiidusti\. 
Most enszineeiiii}; students ieeei\e an 
introduction to this branch of nietallurjiy 
trom early chcmistr\ coinses. 

A present CNample of the need tor 
men trained in process metalluij;\ is 
concerned with current de\clopinents in 
titanium. Tests ha\e shown that this 
metal possesses an excellent \\ci};ht- 
streiigth ratio, a good capacity for woik- 
injz and forminji, and excellent resistance 
to corrosion. All that prevents titanium 
fioni competing with aluminum and 
steel as a constructional material is the 
present expense in obtaining the metal. 
'I'he present status of titaiuum is lenun- 
iscent of the early days of alumiinim, 
when this now common metal was rare 
and expensive. It is hoped and expecte<l 
that metallurgists can do for titanium 
what was accomplished in the case of 
aluminum. 

I'hysiiiil Mrtiilliii i/y 

The othei' di\ ision of metallurgical 
engineeiing, physical metallurgy, is a 



much larger field than process metal- 
lurg\, employing ID to !_' times the 
numhei of men as the latter. I'Or this 
reason, the University of Illinois cur- 
lic'ulum emphasizes physical metallurg\'. 

In broad terms, the pb\sic,il metal- 
luigist takes the raw metal from the 
process metallurgist, and by man\' tecb- 
niipies of alloying, beat treatment, and 
f.abrication, con\erts it into useful aiti- 
cles of industry. A convenient di\ision 
between the physical metallurgist and 
other engineers is that the metalluigist 
is concerned with materials, while other 
engineers are concerned with machines. 
It is thus the province of the metal- 
lurgist to pro\iile stionger and better 
mateiials for the designers in other 
fields to work with. This dut\' necessi- 
tates a close cooperation between the 
metallurgist and the designer, and the 
realization of this fact is providing many 
new opportunities for metalhu'gists in 
;ill phases of industr\'. 

T h e undergraduate instruction i n 
physical metallurgy is chiefly concerned 
with acquiring an intimate understand- 
ing of the internal structure of metals, 
the effect of this structure on the proper- 
ties of the metal, and how the structuie 
can be controlled by variations in metal 
composition, heat treatinent, and me- 
chanical treatment. The s t u d e n t is 
taught to use all the equiiiment avail- 



able to metallurgists, and is gi\en prac- 
tical problems in the use of eiiui|iment 
and the design of treatments of metals. 
'I'he required curriculum includes 
courses necessary for the general train- 
ing of metallurgists; .and technical elec- 
tives are available tor moie specialized 
study, such as: the metallingy of weld- 
ing, powder metallurgy, a<lvanced theory 
of the physics of metals, the metallurgy 
of steel castmgs, etc. 

(iraduate study is not a necessit\' in 
metallurgy, but the few men in the 
field with advanced degrees m.ikes grad- 
uate training a distinct ad\antage. .Men 
with the master's degree are offered jobs 
at salaries of $3U-$5{) per month greater 
than for the B.S., with excellent op- 
portunities for rapid advancement. 

The science of metallurgy is new and 
growing fast. A man who has not yet 
chosen his particidar branch of engi- 
neering, who is concerned about the 
surplus of engineers being trained at 
the |iresent time, and who desires to 
enter an active and dexeloping field 
would do well to consider metallurgical 
engineering as a career.

I'or a tact, in most pluuioKiaphs tin- 
.implit'iiT proper is capable of operating 
almost iiorniall\' tor frequencies hifjher 
than the pickup (mostly because of 
inertia) will Ki'"i"'':'te- It would put our 
almost normal amounts of power at fre- 
quencies higher than the output trans- 
former will pass, and higher than the 
fastest rare at which the speaker (also 
for mechanical reasons) will vibrate. 

One of the greatest sources of trouble, 
and one most frequently ignored, is the 
output transformer between the l.ist 
tube and the speaker. It takes a big, 
hcaw. and expensive transformer to 
(i|ier,ite lower than 100 cycles and higher 
th.in SODO c\cles. The economic reason 
for the use of poor quality transformers 
k'-.m be easily understood — a typical 
transformer such as used in orilin,ar\' 
home record pl.-ners costs about $2.00; 
a high (iualit\ unit would cost close to 
j;U).(l(). The ilifference in expense is 
usu.alU- not profitable to the man\ifac- 
turer. Some customers would ne\er 
notice the difference, and most of the 
rest, conditioned to the usual muddled 
blare of marn railios, don't care. 

Perhaps the most troublesome link of 
the whole chain is the speaker. A small 
fi\e-inch speaker such as found in many 
small players just won't operate over a 



wide range of frequencies. The eight- 
inch and larger units found in consoles 
are better; and the dual s\stenrs using 
one large speaker tor the I<jw notes ( the 
"woofer") ami (jne oi- more special 
small ones ("tweeters") foi- the highs, 
arc excellent. But the best speaker will 
not sound good if lying on the floor, 
nor if stuffed into a little |ilastic box 
along with a cubic toot of amplifier, 
loop antenn.a. :ind assorted inits .•md 
bolts. An acoustical l\ designed enclos- 
ure containing no other equipment will 
do wonders for any speaker. 

Practically all home record pla\eis 
are sections of c o m b i ii a t i o n radio- 
phonographs. .'\ll ladios lia\e audio 
(sound) frequency amplifiers following 
the tuner .section; it is a relatively sim- 
ple matter to include a double-throw 
switch at the input of the amplifier to 
allow it to be switched from the tuner, 
or r.idio section, to the pickup. Since 
pr.ictically all A.M. or standard broad- 
cast radio stations limit the frequency 
of the sound they put on the air to 
5000 cycles to allow stations to be 
crowded closer together in the band, 
little effort is made to allow the ampli- 
fier of the radio to operate over a wider 
range of frequency; therefoi^e that limi- 
tation is imposed on the playing of rec- 
ords using the same amplifier. 

A safe generalization might be that 
the response of most table model phono- 



graphs is do\\n, at 150 and .1500 c.p.s. 
(the low anil high ends, respectively), 
to So per cent of its medium frecpiency 
Willie. (This 50 per cent is just about 
.1 decibels, or discernible steps in loud- 
ness; the ear has a logarithmic response 
to volume.) As a crowning touch, prac- 
tically all radios and phonographs are 
eqiii|iped with a so-called tone control, 
which is nothing more, usually, than a 
small filter which cm be effectiveh' 
u.sed to smother treqiiencies above 2000 
or 3000 cycles. 

This tone control is a highh' mis- 
understood piece of apparatus; it is used 
In the listener to give "full, mellow 
tone" to his amplifier. In a way, it does; 
most amplifiers distort high frequencies 
much more than lower or medium fre- 
quencies, and the suppression, to a large 
extent, of higher tones and overtones 
removes a certain amount of this distor- 
tion along with them. However, in so 
doing the crispness and character of the 
tone is sacrificed. Music played with 
the bass notes emphasized and the treble 
suppressed is indeed soothing and mel- 
low (here enters psychology) and makes 
good backgroimd music ; but few people 
will accept that type of sound as any- 
where comparable to "live" music. It is 
the opinion of certain die-hards (in- 
cluding the author) that music coming 
over the air or played from records

WHY POeS IT HAVE AN UPSTAmS? 

"To make traveling more fun. Tlie idea is to give people more to see and do wiiile riding faster and safer. That 
means more passengers for tlie railroads so that they can keep fares down and still add more comfort to long trips." 






"Railroad comfort comes from many 
things, son. Smootli- fitting parts are 
important. Parts like Diesel engine 
crankshafts, pistons and wheels. That's 
why so many railroad shops use 
Norton grinders and Alundum grind- 
ing wheels tu make parts smooth. 



"Take those side rods on steam loco- 
motives. They get farther over on the 
smooth side thanks to Norton internal 
grinding wheels. And parts are fin- 
ished so accurately with Norton 
quality controlled wheels that they 
last for thousands of miles, Paul. 



"Getting back to comfort . . . modern 
trains travel over 60 miles an hour. 
So, they need smooth rail joints. 
Those joints are welded for safety. 
Then, they're ground smooth and 
slotted with Norton grinding and cut- 
ofl' wheels." 




"Hundreds of other parts 
of modern railroad trains and tracks 
also get a hft from the sure touch of 
Norton Products. So does just about 
any other product you can name. 
That's why I'm not boasting when I 
say that Norton makes belter products 
to make other products better."

>li()ulil sound as much as possible like 
tliat of the original orchestra. 

Another of the problems of reconl 
pla\ini; is noise: noise external to the 
amplifier, from the motor, turntable, 
anil the pickup (incluiliri}; "needle 
talk" — you can usualh' hear the pickup 
arm speak when the volume is turned 
all the way down) ; and the hum, hiss, 
anil cracklinji actually cominfi throii<;h 
the speaker. .Motor and turntable rum- 
i)Ie is reduced b\ fjood mounting; of the 
mii\,ible parts; bu/./.ing and "talk" from 
rile n e e d I e and pickup aim can be 
muffled b\' a solid, more or less sound- 
tii;iit enclosure for these parts. Hum in 
tile amplifier can be made neglifjible b\' 
the use of a certain amount of care in 
the design of the set. .Many commercial 
companies, in the interest of economy, 
are rather skimpy on filters and shield- 
ing, and allow a considerable amount of 
hum, especialK in their smaller sets. 

It is extremely difficult to combat 
noises such as scratch picked up by the 
needle from the surface of records; aged 
records are especially noisy, as everyone 
knows. Noise, like any other .sound, 
musical or otherwise, can be broken 
down into component frequencies, usual- 
l\ very many of them; and there is no 
band of frequencies where noise pre- 



dominates — its components are spread 
over the entire audible spectrum and tai 
beyond. Mut since most of the sound 
ciicigy ill music and voice is concen- 
trated in the medium frequencies and 
it is largeK tin- overtones of low inten- 
sity that i)ccup\ tile higiier end, the 
tone control can be used to eliminate 
these o\ertones and a larger percentage 
of the noise than of the music. 

Well shaped and highly polish e d 
needles produce less scratch than other 
kinds; semi-permanent needles are usual- 
ly better in this respect than the cheaper 
ones. Cactus and needles of similar 
composition reduce scratch in the same 
way as the tone control — b\' their lack 
of response to high frequencies. Keeping 
records free from dust and surface mar- 
ring helps a great deal in eliminating 
noise. 

After 68 years of progress, the prin- 
ciples of Bell's recording machine are 
still the basis of even the most modern 
transcription methods. .Main of the

WHiile cruising the Pacific in a P.C., 
he came close to joining Neptunis Rex 
several times, but didn't quite cross into 
the "you-all" hemisphere. He is a mem-

PROBLEM — You have an aircraft radio receiver. 
To operate it, the band selector and tuning elements 
must be adjusted. You v^ant to arrange it so that 
these adjustments can be made right at the receiver 
or from a remote point. How would you do it? 
THE SIMPLE ANSWER— Use S.S.White remote 
control flexible shafts to connect the tuning dials 
on the receiver to tuning cranks on a remote control 
unit. This arrangement leaves you free to mount the 
control unit anywhere you want, and assures you 
of smooth, sensitive tuning from any distance up 
to 50 feet or more. The shafts can be readily run 
around turns, along walls, under flooring as condi- 
tions in different aircraft may require. Any required 
degree of sensitivity can be obtained by connecting 
the shaft through simple gearing. 



This is just one of hundreds of 
remote control and power drive 
problems to which S.S.White 
flexible shafts provide a simple 
answer. That's why every engi- 
neer should be familiar with the 
range and scope of these "Metal

5^^^BOL OF 85,000 YEARS Of KH© 



>NV^^ 



If you liad been born 85,000 years an;o antl were 
still alive, think of all vou would know about 
what happened on earth. 

And if vou had devoted all those vears to work- 
ing with one particular material found on earth 
. . . say aluminum . . . think what vou would 
know about that. 

Actually, man has known of aluminum for less 
than 150 vears and didn't really start to use it 
comincrcially until 1888 when Alcoa started pro- 
ducing it. Yet in Alcoa's employ today is a group 
of men and women who possess a total of 85,000 
years of aluminum working knowledge. 

These people. 2,900 of them, proudlv wear tills 
button as members of the Alcoa 25-Year Service 
Club. Many have been in the familv longer than 
25 years. Their jobs range all the way from mill 
hand to president, from engineer to chairman of 
the board. 'I'liey are a fourth of all the employees 



Alcoa had 25 years ago. pretty good indication 
that it's "a good companv to work for". 

But here's the most significant point: Sixty-one 
years ago, when Alcoa started, only five men 
were employed. Today about a million people 
have jobs in the aluminum industrv, an industry 
comprised of: companies who produce aluminum 
from ore; companies who smelt aluminum scrap; 
others who make semi-finished aluminum prod- 
ucts; and hundreds of companies who manufac- 
ture useful articles in which aluminum plays an 
essential part. 

Today the same pioneering spirit that marked 
the founding of this industry is evident in 
Alcoa's laboratories, mills and foundries. Here 
men are developing new uses, new techniques 
that promise even more for the future of alumi- 
num. Aluminum Company of America, Gulf

THE TECHNOGRAPH 




Glass that you can twist, bend, roll,.. 



This is a ribbon of glass so thin that it 
takes about unc llioiisaml thictinesses of it 
to make a stack an inch high. 

It is so flexible that you can roll it on a 
reel, twist it into a spiral, wrap it around 
your arm. 

If you should test it electrically, as 
Corning scientists have done thousands 
upon thousands of times, you'd find that 
it has superior electrical insulating and 
dielectric properties — equal to high-grade 
mica. 

One of the first experimental uses of 
Corning ribbon glass has been to alternate 
strips of it with metal foil and fuse them 
together to make electrical capacitors — or 
condensers — similar to those made of 
mica for television, radio, and other elec- 
tronic equipment. 



Ribbon glass capacitors, which can be 
uniformly produced by machine, have al- 
ready shown many advantages over those 
made with other materials. 

Being hermetically sealed, they need no 
enclosing case. They can operate at tem- 
peratures which are too high for other 
capacitors to withstand. They do not de- 
teriorate with age or continued use. Small 
ones can do the job of conventional capac- 
itors of larger size. And for certain instal- 
lations only a ribbon glass capacitor will 
serve. 

And Corning research indicates that mak- 
ing capacitors is not the only problem that 
ribbon glass may solve. It can be laminated 
with resin and then cut, formed, shaped 
and used for other electrical purposes. 

Because ribbon glass is uniformly thin, 



it has already been considered for such 
other uses as microphone diaphragms and 
windows for Geiger counters that measure 
radio-activity. 

Glass ribbon is another striking example 
of how Corning, noted for its Pyrex brand 
products, has developed glass into a most 
versatile engineering material. 

That's why we invite you — when you've 
finished school and started work— to call 
in Corning before your product planning 
reaches the blueprint stage. Corning Glass

Is a cable covering flameproof? Will it resist high tem-

Long before a cable is manufactured, questions like 
these are answered in the Okonite laboratories, proving 
ground and in various testing departments of the 
Okonite plants. The picture above shows a flame test.

PRODUCTION METHODS have become a 
good deal more technical and compli- 
cated in the last few years. There is a big 
difference between the way we do things 
now and the way we 
did them when I left 
the Allis-Chalmers 
Graduate Training 
Course to work in the 
machineshopin 1930. 
That is \\ liy there are 
more and more op- 
portunities in the 
manufacturing end 
of the business for 
CARL MALMBERo ^^^^„ engineers who 
get a thrill from watching a project grow 
from a roll of blueprints to a big electric 
power installation or machinerv for a 
giant processing plant. 

Close Coordination 

In my section of the shop we specialize in 
fabricating machines and parts from sheet 
and plate steel. We work closely w ith the 
design engineers to develop the most eco- 
nomical way of producing their designs 
and we do much designing on our own. 
We work closely with every other manu- 
facturing department, because more and 
more Allis-Chalmcrs products are being 
designed to replace cast members with 
welded members, and in my work we do 





Machining speed ring for a 55.000 hp turbine on a 40' boring mill, one of 
the largest in the country. Many A-C machines and methods are unique 
because of the tremendous size of worii pieces and wide variety of operations 
required in building the world's greatest range of industrial equipment. 



the welding for the whole plant. 

One recent interesting project was the 
fabrication of stainless steel buckets for 
impulse-type hydraulic turbines to replace 
the old cast-type buckets. Working with 
design engineers and hydraulic engineers, 
our tank and plate specialists developed a 
design and method of manufacturing that 
produced buckets with several times the 
life of the old type. 

Opportunities Everywhere 

New developments in every department 
mean almost endless opportunities for 
young engineers. Right now, the erection 
shop is building a big crusher for process- 
ing taconite in the Mesabi range, and we 
are supplying most of the other ore proc- 
essing equipment for this gigantic plant, 
too. At our Norwood plant, engineers 
have completely rebuilt the production 
system on motors and small pumps for 
greater elTiciency and lower costs. 



In fact, here at Allis-Chalmers there are 
big opportunities for young engineers in 
all phases of engineering work — design, 
research and development, manufactur- 
ing, sales and erection — in nearly any in- 
dustry you can name. For Allis-Chalmers

power . . . mining and ore processing . . . 
pulp and wood products . . . flour mill- 
ing . . . steel . . . agriculture . . . public 
works . . . for even' basic industry. 

The thing that influenced me most when 
I left the University of Illinois to join 
Allis-Chalmers, was the tremendous 
breadth of opportunity. Some of my 
friends from that GTC class of 1930 are 
sales engineers now, some are design en- 
gineers, some have traveled around the 
world w ith erection crews. I chose manu- 
facturing because I like to see things take 
shape before my eyes. I tried a good many 
things before I made my choice and my 
choice has been good.

THE TECHNOGRAPH 




Year by year, month by month, oil industry chemists find new, 
fascinating possibihties in the hydrocarbon molecules that make 
up petroleum. They have learned many ways to convert them into 
new and more valuable molecules. 

One result of this experimentation has been a flexibility that 
permits stepped-up output of whichever petroleum products are 
most urgently required. When the primary need was for vast quan- 
tities of aviation gasohne to help win the war, research showed how 
it could be produced. In a peace-time summer, the great demand 
is for an ocean of automobile gasohne; in winter, less gasohne and 
more fuel oil are needed. Research tells the industry how to make 
petroleum serve the public more efficiently. 

Standard Oil is a leader in petroleum research. Many remark- 
able developments have come from our laboratories; many more 
are sure to come, in the future, if we continue to attract good men, 
furnish them with the most modern equipment, and provide an 
intellectual climate in which they can do their best work. 

We are continuing.

magnets of diffcicnt strengrhs. The 
values thus obtained are used, in con- 
junction with a set of previously de- 
teiniined calibration curves for each 
magnet, to obtain the total thickness of 
the coating and the ndatixe thickness of 
the copper and nickel la\ers. 

Composite coatings, nickel over cop- 
per on steel, are used extensively in 
automotive industries for economical 
protection. 

The thickness of each component 
layer of similar coatings can be mea- 
sured to an accuracy of about 15% with- 
out causing any damage to tlie tested 
fiiush. 

Ozone Water Treatment 

The world's largest ( )/()nator water- 
treatment generator unit has been in- 
stalled in a Philadelphia filtration sta- 
tion by the Welsbach Corporation. 

Sparking of glass electrodes creates 
the gas, ozone, which removes taste and 
odor from ordinary water. Treatment 
will require an average of 200 kilowatt 
hours for each million gallons. 

Color Film 

Dul'ont has made a basic improve- 
ment in photographic color film for the 
motion picture industry. 

The result of many years of research, 
this product is an entirely new syn- 
thetic polymer which is also a color 
former. It takes the place of both the 
gelatin binder and the color former 
heretofore used in color films. Combi- 
nation iiitc] a single material results in 
excellent color reproduction and im- 
pro\es image sharpness. This film is for 
the printing of 35mm. positixes for 
theaters. 

New Hydraulic Oil 

For use in h\(liaulicall\ operated ma- 
chine tools that pressure-feed lubricant 
away from the hydraulic system, Sun 
Oil company has introduced a new dual- 
purpose oil. 

Called Lubeway, the new lubricant 
has already been subjected to more than 
a year of exhaustive testing in machine 
tool builders' laboratories and imder 
regular production conditions in indus- 
try. 

Ordinary hydraidic oil lacks the film 
strength and metal-wetting properties 
needed for lubrication. These deficien- 
cies caused excessive wear and made 
close tolerances and fine finishes impos- 
sible. The new oil, a blend, gives good 
lubricating as well as hydraulic perform- 
ance.

When you think of Du Pont research, 
you may think first of Wihnington, 
Delaware. Actually, only eight of the 
Company's 36 research groups are 
located there. Du Pont scientists now 
pursue their studies in 11 states scat- 
tered from Connecticut to Texas. 

Each of these laboratories is a self- 
contained operation. It may be de- 
voted in part to fundamental re- 
search and applied research, or to 
investigations looking to the devel- 
opment of new products — sometimes 
a combination of these activities. 

An unusual Du Pont laboratory 
is one opened last year at Newburgh, 
New York. 

Inside the Laboratory 

In the three-story building at New- 
burgh, .scientists have at their dis- 
posal the most modern equipment 
for study of coated fabrics and plas- 
tic sheetings under all sorts of con- 
ditions. For example, a new product 
can be tested in a room maintained 



at a temperature of —20" F. In other 
rooms, the effects of high tempera- 
ture and humidity can be studied. 
Equipment is available for testing 
tensile strength, tear resistance, fad- 
ing, flex and flame resistance, and 
many other characteristics. One of 
Du Pont's 33 Libraries has quarters 
in the building; there is a photo- 
graphic darkroom, as well as offices, 
conference and work rooms. 

The Newburgh Laboratory works 
closely with the adjacent plant, which 
makes "Fabrikoid" pyroxylin coated 
fabrics, "Fabrilite" vinyl resin coated 
fabrics and plastic sheetings, "Ton- 
tine" washable window shade cloth, 
bookbinding materials, and other 
coated and impregnated fabrics and 
plastic sheetings for many uses. 

Research at Du Pont 

Research has long been a major ac- 
tivity at Du Pont, and it flourishes 
in an atmosphere of appreciation, 
encouragement and patience. The 
new products, the new plants, and 
the new and better jobs of the years 
to come will develop from the pains- 
taking research programs being car- 
ried on today in the laboratories.

Choice of Careers 

Each of the Du Pont manufacturing 
departments conducts continuous 
research. They operate much like 
separate companies, with interests 
ranging from heavy chemicals to 
plastics and textile fibers. Each holds 
challenging opportunities for college- 
trained chemists and pliysicists, as 
well as chemical, civil, electrical, in- 
dustrial and mechanical engineers, 
also those speciahzing in production, 
sales and many other fields. 

In this alert, ever-growing organi- 
zation, young graduates can choose 
from a variety of careers the one 
that suits them best as their ability 
and interests develop.

of the final tests on heavy machiner\. 
Machines such as turbines operatinsi at 
maximum efficiency will have a certain 
noise level. If the machine is not operat- 
ing at this efficiency the change in noise, 
though not discernable by the human 
ear, is easily and conveniently indicated 
by this instrument. 

Noise is distracting no matter what 
type of work a person is doing. There- 
fore many employers are beginning to 
use the sound-level check to keep the 
efficiency of their employes at a maxi- 
mum.

first award of $3,000 in the Lincoln Foundation "Welded Bridges of the 
Future" competition. (Courtesy of James F. Lincoln Arc Welding Foun- 
dation.) 



Airplane-Type Bridges 

A "new look" for bridges may result 
from a meeting at the University of 
Illinois last year of Prof. Wilbur M. 
Wilson, internationally known engineer, 
and James F. Lincoln of arc welding 
fame. Professor Wilson conceived the 
idea that welding could be used m 
bridge construction, not just as a re- 
placement method for rivets antl bolts, 
but as an entirely new medium of con- 
struction. He felt that engineers should 
be encouraged to think about entirely 
new methods. As a result of that meet- 
ing, a competition for designs of welded 
bridges of the future was arranged. 

The purpose of the competition was 
to give an opportunity "for determin- 
ing whether structural designers, freed 
from present limitations and restrictions, 
will employ new concepts of economy, 
performances, and beauty so that sub- 
stantial progress will result." 

The result of the bridge competition 
may well be to save weight, material, 
and cost on future spans. Some bril- 
liant new ideas for bridges were pre- 
sented in the 120 designs submitted in 



Decreasing Contamination 

Use of mortars and pestles made of 
Carboloy cemented carbide practically 
eliminates the danger of contaminating 
materials being pulverized or crushed. 
The pestles are tipped with the metal 
and the mortars are solid carbide. 

The carbide mortars and pestles are 
already being used by various industrial 
and pharmaceutical concerns in then- 
laboratories. The solid hard metal mor- 
tar is usually about 3 inches in diameter. 
It can either be mounted in a holder or 
placed flat on a work bench. The pestles 
are made by brazing or soldering a half- 
round or similar tip of carbide metal 
onto a "softer" stainless steel holder of 
ccin\i-nient size. 

New Farm Power 

The tir.st track-type tractor to bear 
the John Deere name, the "JMC", is de- 
signed to fill power needs on extreme- 
ly hilly farms, and in orchards, vine- 
vards, woodlands, muckland, bogland. 



the competition, according to Prof. Wil- 
son, who headed the judging committee. 
Prof. Thomas C. Kavanagh of Pennsyl- 
vania State College won the $3,000 
first prize. 

Influence of airplane design is shown 
in the plans for the welded steel bridges 
submitted this year. Like a frame of an 
airplane, the winning design is a solid 
single unit instead of being built-up by 
bolting and riveting. 

More than Meets the Ear 

The popuIarit\ of amateur programs 
judged by audience reaction necessitates 
an analysis of the audience's opinion that 
is independent of human judgment. The 
("i. E. sound-level meter solves this 
problem by giving an impartial, scientific 
indication of noise level. 

A range of 20 to 120 decibels per- 
mits measurement of almpst any noise. 
Even quiet background noises can be 
measured with this meter. Tests with 
the G. E. meter indicate whether noises 
are obnoxious, or if noise reduction 
methods are effective. 

In factories the meter is used as one

The Plastic Faiiiilj Tree 



Itii ihin Kwiv. Cli.E. TtO 



"P/tis/ir: from the Greek verb pliisso. 
to form ; . . . capable of being molded 
into various forms . . ." This definition 
from Webster may be a little hard to 
accept for anyone who has had the mis- 
fortune of getting his head caught in 
a three-cushion billiard match. Yet the 
billiard balls are made of a material 
that we may rightfully call plastic, 
though a cue-ball could hardly be mold- 
ed into something else. The word "plas- 
tic" was coined about 1930 and is meant 
to cover a wide range of materials that 
are either entirely synthetic or result 
from a chemical modification of natural- 
ly occurring substances. 

After this very brief introduction, 
a climb through the plastic family tree 
is in order. 

Early Dcvflop/iicnt 

The first generally accepted plastic 
was made in 1865 by a Birmingham, 
England, chemist named Alexander 
Parkes. He based his product on nitro- 
cellulose (or cellulose nitrate) and it 
had a marked resemblance to horn or 
ivory. The name given to the new ma- 
terial was Parkesine and, though it was 
used in England, it was not exploited 
in this country until twelve years later. 

In that interval an American, John 
Wesley Hyatt, working along the same 
lines as Parkes but independent of him, 
discovered a substance almost identical 
with Parkesine. The year of this dis- 
covery was 1869 and Hyatt's product 
is known to everyone under the fa- 
mous name of celluloid. In that same 
year, another investigator, D. W. Spiel, 
made the same discovery that Parkes 
and Hyatt had made; but the honor 
of inventing and naming celluloid be- 
longs solely to Hyatt. 

Two years after the invention by 
Hyatt, the Celluloid ^lanufacturing 
Company was formed ; the basis of the 
process was a gelatinization of nitro- 
cellulose (pyroxylin) with alcohol and 
subsequent heating with camphor. 

While on the subject, it would be 
well to mention that another plastic 
named xylonite, which was similar to 
celluloid, appeared on the market in 
1877. There were, of course, many 
others which were brought out at this 
time; but all of the products were al- 
most identical with the discoveries of 
Hyatt and Parkes. 



In 1890, a German chemical firm 
pioduced a tough, horn-like material 
which was similar to celluloid but was 
made somewhat differently. The French 
made the discovery about the same time 
and the two interests merged to form 
the Compagnie Internationale de la Ga- 
lalith. This new plastic was made by 
treating casein with formaldehyde ; 
and it found wide application in the 
manufacture of buttons, knitting pins, 
brooches, etc. 

The last plastic of this particular era 
which we will mention was called eri- 



It seems that the field of plas- 
tics has grown up pretty much 
like an unpruned tree — in all 
directions at once. However, 
despite the network of roots in 
the "fertile earth of chemistry" 
there is no trunk of unity con- 
necting all the branches to- 
gether. 

This article describes some of 
the interesting history, proper- 
ties, and everyday uses of the 
most important members of this 
heterogeneous aggregate called 
plastics. 



noid. It was similar to celluloid in its 
physical properties and made its appear- 
ance around the time of the First World 
War in 1914. 

Numerous other plastics belong to the 
early period of investigation, but de- 
tails of their development follow along 
the lines already discussed. It is hoped 
that the brief sketch given above of 
the first plastics will serve to give the 
reader some "new" ideas about the 
"new" field of synthetics. 

Thermosetting Plastics 
The year 1907 saw the first really 
outstanding invention in the field of 
plastics. Dr. L. H. Baekeland, of the 
I nited States, produced the first ther- 
mosetting powder in that year. His name 
is perpetuated in the tradename gi\en 
to his discovery, Bakelite. 

Previously, all attempts to obtain ;i 
thermosetting powder had ended in 
failure in that the product could not 
readily be molded. Dr. Baekeland's proc- 
ess produced a substance that was fluiil 
at the start of its manufacture and 



could therefore be poured into molds, 
or otherwise shaped. Then, when heat- 
ed, the flin'd set to an infusible mass 
that could not be melted when heated 
further. 

Bakelite is made by heating formalde- 
hyde with phenol in the presence of 
ammonia; the physical nature of the 
product is dependent upon the catalyst 
and the amount of heating employed. 
Everyone is familiar with Bakelite in 
some form, whether it appears as a 
fountain pen, phonograph record, or one 
of many other equally common items. 

It might be well at this point to ex- 
plain what a thermosetting powder is. 
A good correlation is available to help 
in this illustration. Imagine that the 
molecidcs of the materials used are very 
small links which are hooked together 
in the course of the reaction. Thus long 
molecules are formed which may be 
pictured as chains. In the case in ques- 
tion, these long chains have an oppor- 
tunity of being hooked together (cross- 
linked) by the I'emaining small mole- 
cules. This second step takes place upon 
heating in many cases. The material can 
n(jw be thought of as an extremely com- 
jilicated network which is quite rigid. 
It is eas\', then, to imagine that as this 
process of linking the chains together 
proceeds indefinitely, the product be- 
comes more and more hard. The name 
"thermosetting" then, means just that; 
upon heating the material sets and be- 
comes hard. 

(Uyl^tals 

One of the most important plastics 
derived from the use of glycerine is that 
involving phthalic anhydride. The early 
research in this direction resulted in the 
discovery of the glyptal resins which 
were used as bonding materials in mica 
insulators. These resins were all thermo- 
setting as was the case with most of the 
early plastics. 

In the use of ghcerine, the long 
chains were linked together by the re- 
action of the three hydroxyl groups in 
the glycerine molecule. It was recog- 
nized that one of these hydroxyl groups 
would have to be blocked from further 
reaction if a fluid product was desired. 
Eater work in that direction demonstrat- 
ed that this could be accomplished by 
adchrig a small amount of an aliphatic

SILICONES IN REVIEW 



itif llvnrif Kahn. 1'h.lC. '."iO 



(Information courtesy of Dow-Corning, and General Electric) 



The first orjianic silicon coiiipouruls 
were prepared in the laboratories of 
Friedel, Craft and Ladenbiirg in lS7(t. 
The basis of most of our present knowl- 
edge about organic sihcon chemistry, 
however, stems from Kipping, who 
started his 43 years of research on or- 
ganic silicon compounds in 19(11. 

There are several ways of making 
polymer chains containing silicon atoms. 



One of the most important 
limiting factors in the design of 
equipment has always been the 
selection of proper engineering 
materials. 

Shortly before the war, steel, 
iron, nickel, chromium and cop- 
per were used almost exclusive- 
ly, but in recent years alu- 
minum and its alloys have 
been used in ever increasing 
amounts. Similarly, silicones 
have become very important en- 
gineering materials. Their uses 
as lubricants, hydraulic fluids, 
mold release agents, and elec- 
trical insulation, to mention a 
few, are due to the many di- 
versified advantages. 



but onh' the siloxane or silicone cliains 
(silicon and oxygen atoms appear in al- 
ternate position ) have become impor- 
tant. Therefore, the other existing 
chains will be briefly summarized : 

1. The silicon-silicon chains are un- 
stable since they are subject to oxida- 
tion, thermal dissociation, and hydroly- 
sis. 

2. The silicon-carbon chains, such as 
one involving the phenylene radical 
(C^H^), are quite stable; however, ex- 
periment has proved that the chains are 
qvu'te short. Even though this difficulty 
can be overcome by hydrolysis and cross- 
condensation, these polymers have not, 
as yet, been developed. 

There are at the present time two 
important methods of preparing the or- 
ganic silicon monomers (R^.SiCL.) 
which, though they are usually not iso- 
lated, may be considered the starting ma- 
terial for the polymer. From laboratory 
experience the (irignard reaction is a 
very logical method. Silicon tetrachlo- 
ride and a (irignard reagent, such ,is 
methyl magnesium chloride in an inert 
solvent are reacted and recycled luitil 
the product is mostly (CH3)2SiCI_,. 



The (CHJ^SiCl and (CH;,)4Si have 
to be separated from the mixture. 

Direct (.omtyoiinding 
The second important commercial 
method is known as the direct method. 
Here silicon and methyl chloride are 
reacted in the presence of a copper cata- 
lyst. The resulting mixed methylchloro- 
silanes and silicon tetrachloride are then 
separated by fractional distillation. 

The methyl-dichlorosilane, which re- 
sults from both of the above methods, 
is hydrolyzed and then immediately 
forms polymers by a condensation re- 
action. 

One of the most important things 
at this point is to get the desired chain 
length. This can be controlled to 



a large extent, by the proportion of 
(CH3)3SiCI; or if cross-linkage is de- 
sired some CH.jSiCl^ might be added. 
The usual controlling factors, such as 
the temperature and viscosity are, of 
course, also very important in determin- 
ing the size of the chain. 

Emphasis has been placed on methyl- 
substituted molecules since aromatic 
groups result in a brittle polymer, while 
a polymer containing alkyl groups high- 
er than methsl is very pliable. 

Oils (ind (iriasrs 
One of the first and the most im- 
portant silicones to be developed was 
methyl silicone oil. The repeating unit 
appears from two to about ten times

THE TECHNOGRAPH 



DR. JOHN D. RYDER 



Uti IHvli llntmnzfi. 3f.K. *.7# 



Doctor John D. Ryder, formerly of 
Iiiwa State College, is the new head of 
the Electrical Engineering department. 
He has succeeded Dr. W. L. Everitt, 
will) is now dean of the College of En- 
gineering. 

Since his appointment by the board 
of trustees. Dr. Ryder has become rapid- 
ly acquainted with the various duties 
required of his office. And he already 




DR. JOHN D. RYDER 

has become recognizable to many of the 
engineering students on the north cam 
pus. 

Dr. Ryiler, a personable and relative- 
h' \oung man, was born in Columbus, 
Ohio, in 1907. He received the B.E.E. 
degree in 1928 and, a year later, his 
M.S. degree from (^hio State Univer- 
sity. 

After earning the latter degree, he 
obtained a position with the (General 
Electric Company ; he specialized in elec- 
tronic work and the development of 
thyratrons under H. C. Steiner. 

In 1931 Dr. Ryder joined the Bailey 
Meter Company of Cleveland, Ohio, as 
supervisor of the electrical and elec- 
tronic section of the Research labora- 
tory. He holds 24 patents on this work, 



covering temperature-recording and au- 
tomatic control applications of electron- 
ics, f'quipment now being manufactured 
inider these patents include the Haile\' 
"Pyratron" group of devices and the 
(icneral Electric and Weston photoelec- 
tric iiotentiometers. 

While still at the Research depart- 
ment of the Bailey Meter Company, he 
furthered his graduate education by 
studying mathematics and atomic physics 
at the Case School of Applied Science. 

In I'Hl Dr. Ryder became an assist- 
ant professor of electrical engineering 
at Iowa State College. He continue.i 
at that position until 1944, when he 
became Professor of Electrical Engineer- 
ing in charge of electronics courses. In 
that same year he was awarded the 
Ph.D. degree in Electrical Engineering 
by Iowa State College. From September, 
1''44, to April, 1946, he was temporari- 
h professor-in-charge of the Electrical 
Engineering department. 

He became Assistant Director of the 
Iowa Engineering Experiment Station 
in 1947. He continued in that capacity 
until September of this year, when he 
assumed the position he now holds here 
at the University. 

As can be seen from his educational 
and practical experience background. 
Dr. Ryder is exceptionally qualified for 
the work he is doing here. 

He is the author of two text- 
books. Electronic Engineering Principles 
(Prentice-Hall, Inc.), and Nehvork. 
Lines, and Fields (Prentice-Hall, Inc.) ; 
the former is currently being used in 
the course, E.E. 340. He has also writ- 
ten many other authoritative papers on 
D.C. and A.C. motors, vacuum-tube 
voltmeters, network analyzers, and elec- 
tronics. 

Dr. Ryder is a member of many asso- 
ciations and organizations. He is a mem- 
ber of electronics committee, the educa- 
tion committee, and chairman of the 
electronics education subcommittee, all 
of the American Institute of Electrical 
Engineers. He is also a member of the 
American Association for the Advance- 
ment of Science, and numerous honor- 
ary fraternities, some of which are Tau 



Beta Pi, Eta Kappa Xu, and Sigma 
Xi. 

Dr. Ryder was married in 1933. He 
has a 12-year-old daughter, Barbara, 
and a son mcknamed "IVlac" who is 
nine years old. 

He has a very interesting hobby — 
color photography — and owns over 
2,000 of his own Kodachrome photo- 
graphs of western national parks. He 
also was a radio "ham," operating his 
own station, WOVDE. When he can 
find time, he also plays tennis. 

As yet, Dr. Ryder has planned no 
drastic innovations in the department he 
is heading. The many fine improvements 
made by the department in recent years 
makes one believe that it will be diffi- 
cult to add any startling improvements. 

The combination of education and 
interest in activities marks Dr. Ryder 
as one of the more distinguished per- 
sonalities and educators on the campus. 
And if the Electrical Engineering de- 
partment rises to even greater heights, 
to Dr. Rvder will be due the credit. 




This is the kind of Prof he ain't. 



0\er in Africa some of the native 
tribes have the custom of beating the 
ground with clubs and uttering spine- 
chilling cries. Anthropologists call this 
this a form of primitive self-expression. 
Over here in America we call it golf.

YOU and the I. S. P. E. 



Itfi i'onnit' Minnivh^ t.E. '."il 



Have you heard of: 

A supply engineer? 
A floor engineer? 
A cuisine engineer? 

Ir is not unusual to find these types 
(it "engineering" refer to shipping clerks, 
linoleum layers, and short-order cooks. 

Kngineering as a respected and time- 
honored profession is not uncommonly 
■ ■i used to disguise a run-of-the- 

Ei 3 mill job. The above, how- 
I ever, are only trivial ex- 
I I amples of the misuse of the 
— '.a word "engineer." Far more 
' ■^ serious than these are the 
cases of men who lay out the plans for 
large engineering projects and who sign 
drawings and specifications in the capac- 
ity of qualified engineers. Failures of 
buildings and machines designed b\' "en- 
gineers" leave a dark stigma on the en- 
gineering profession. 

What is done about such individuals 
who, though lacking the practice or 
proper education, assume the responsi- 
bilities, trust, and confidence of an ex- 
perienced engineer? This is one of the 
man\' items on the working agenda of 
the National Society of Professional En- 
gineers. 

"Undoubtedly, students are familiar 
with their own specialized professional 
societies such as the A.S.C.E., A.I.E.E.- 
I.R.E., and A.S.M.E. Perhaps a few, 
having heard of the National Society 
(abbreviated N.S.P.E.) have thought, 
it an engineering society outside of their 
own fields. 

The N.S.P.E. 
N.S.P.E. is not limited to one phase 
of engineering; it is an association that 
is comprised of qualified registered en- 
gineers in all the actual and related 
fields of engineering. Unlike the spe- 
cialized societies, its main function is 
not technological development, but rath- 
er the profession/il, economic, and socidl 
development of the average engineer. To 
the American people, it is the voice of 
all professional engineers "in all mat- 
ters affecting their status as members 
of a profession and concerning the wel- 
fare of the public whom they serve," as 
expressed by one of the Society pam- 
phlets. 

A fairly young organization, N.S.P.E. 
was formed in 1934 by the joint efforts 
of four independent state engineering so- 
cieties wliose emphatic objective was the 



10 



"promotion of the welfare of the engi- 
neer." Since that time membership has 
grown to 22,000 in the .34 state societies. 
To ever>' member, N.S.P.E. has very 
much the same significance that the 
American Medical Association or Amer- 
ican Bar has to members of the medical 
or legal professions. 

Following the general outline of the 
Federal C]overnment, N.S.P.E. is divid- 
ed into three levels: National, State and 
Local. The National group is the gov- 
erning body, it consists of the Hoard of 
Directors, one from each of the State 
societies. From this group the national 
officers are elected. State societies such 
as the Illinois Society of Professional 
Engineers have their own self-governing 
bodies and are further divided into the 
local chapters. The organizational chart 
shown on this page gives some idea of 
these various divisions of the Society. 

And You 

The preceding paragraphs have given 
a rough outline of the N.S.P.E., its 
founding, primary purposes, and organi- 
zational set-up. However, The Tcchno- 
graph, as a student engineering publica- 
tion is naturally interested in this or- 
ganization from the student's point of 
view. 

For the sake of convenience, take Pat 
Jones, an average engineering student at 
the University of Illinois. He could be

Pat, having read the preliminary ma- 
terial of this article, scratches his head 
and says, "Well, N.S.P.E. sounds pretty 
good, but it seems to me that oidy prac- 
ticing engineers belong to it. 1 never 
heard of it having student chapters like 
the A.S.A.E. or the A.I.Ch.E." 

Yes, students can become affiliated 
by joining a local chapter of the State 
society, either in the town of their 
school, which in the case of the Uni\er- 
sity of Illinois would be the Cham- 
paign County chapter, or the local chap- 
ter in their home town. Student chapters 



This article is concerned with 
the National Society of Profes- 
sional Engineers, a fairly young 
organization which includes pro- 
fessional men in all phases of 
engineering and which acts as 
the voice of the American Pro- 
fessional Engineer in social and 
economic fields beyond the 
scope of the slipstick world. 



will probably never be organized since 
one of the basic interests of the Society 
is the social intermingling of its mem- 
bers. Thus, students are not segregated 
into their own groups, but are free to 
become acquainted with professional en- 
gineers of all ages and types of experi- 
ence at the monthly chapter meetings. 
"One thing I'd like to know," Pat 
asks, "is what sort of an examination 
I have to take before I can become a 
registered engineer? Does the Society 
have anything to do with this profes- 
sional engineering registration? And 
why do I have to register anyway?" 

Engineer at Targe 

Why registration? As emphasized at 
the beginning of this article, a profes- 
sion is judged by the work of its people. 
Thus, the purpose of this professional 
registration is to draw a dividing line 
between the qualified members of a pro- 
fession and those unqualified to prac- 
tice. As in the case of registered medi- 
cal men and lawyers, so public recogni- 
tion is also granted to those licensed by 
state authority to practice engineering. 

What does N.S.P.E. have to do with 
registration? Contrary to many opinions,

THE TECHNOGRAPH

It is a tributary of the Ohio Ri\er ; 
it has a drainage area of 5.3 square 
miles; it owns a U. S. Geological gage 
station located at Latitude 40° 06' 40" 
and Longitude 88° 13' 40". The iire- 
ceding statement may be used, but the 
engineers of north campus refer to it as 
"The Boneyard." "Beloved Boneyard," 
that is! 

The slow-moving, self-cleaning trash 
barrel of this campus is not always 
placid. The creek reminds one of \LTrk 
Twain's character, "Topsy," in that it 
apparently doesn't have a source, but 
just grows. The main supply of water 
is from rain and "Lake Neil," occa- 
sionally resulting in rampages which 
threaten to wash out most of our en- 
gineering campus. The all-time maxi- 
mum flow was recorded on the after- 
noon of July 15, 1948. At that time 
the discharge recorded at the gage sta- 
tion behind Civil Engineering Hall was 
345 ft.' see. The minimum, however, 
was recorded a short time later, when 
the discharge dropped to 1.0 ft.^ sec. on 
September 27, 1948.

The weir under the E.E. research lab is used for measuring the flow rate 
of the Boneyard. No floating ping pong balls are visible in this shot. 



The Boneyard flow gage shown 
here recorded an all-time high and 
on all-time low discharge rate 
within the short space of two 
months lost year. 



We hear the Ceramic engineers are 
preparing to shift into capacity produc- 
tion of bricks. Apparently the city of 
L rbana is unable to provide the neces- 
sary 2\4\H blocks for repairing the rap- 
idly disintegrating sidewalk along Good- 
win street. The ceramists, who don't 
appreciate walking in muck, are willing 
to furnish the missing bricks if some- 
one will insert same. 



A new release from the University 
of Illinois Press, entitled "History of 
the Development of Building Construc- 
tion in Chicago," will prove to be a 
great boon to structural and foundation 
engineers in or near Chicago. 

The book contains a detailed and pre- 
cise account of the histories of the foun- 
dation and structural work involved in 
the construction of many of Chicago's 
more important buildings. Although cov- 
ering all ground between Chicago's 
founding up until 1948, the book high- 
lights the great building era between 
1871, the year of the Chicago fire, and 
1915; for it was during these years 



that foundation design came into being 
as another major phase of engineering. 
Frank A. Randall, the author, com- 
piled this data from his many years of 
experience as a consulting engineer of 
Chicago. Mr. Randall has often been 
a special lecturer to senior civil engi- 
neering students here at the University.

CONGRATS to C. C. Wiley, pro- 
fessor of Civil engineering, on his fourth 
edition of the Route Surveying textbook. 
Professor Wiley has rewritten the book 
which he wrote with the late G. W. 
Pickels. 

The new edition follows the previous 
book closely as to content; howe\er the 
material has been brought up to date 
in methods of usage. Additional mate- 
rial has been written on railroad and 
highway curves, with other necessary 
data on various topics included. 

The frontispiece of the new edition 
tells of its dedication by Professor Wiley 
to (i. W. Pickels, a professor of Civil 
engineering, and a former associate and 
close friend.

ENGINEERING COUNCIL 

Kngiiu-ciiiifi Opt'ii House! That's tlu- 
main topic being talked over across the 
engineer's round table. The ball is be- 
ginning to roll and it sounds as if this 
will be one of the biggest events on the 
campus this year. 

The show is, at present, scheduled 
tor next spring; but before then there's 
idts to be done and e\ery minute is 
\aluable. As things stand now, each of 
the engineering departments will ex- 
hibit a display representative of their 
field of work. When the big day comes, 
there will be guided tours through the 
\arious engineering buildings and the 
displays will be demonstrated by mem- 
bers of the societies. It will be an excel- 
lent opportum'ty for everyone to become 
acquainted with what the different 
branches of engineering are doing. Doii't 
forget! You're invited and so is anyone 
and everyone ; the more, the merrier. 
(In fact, you can help!) 

.'Ml the latest information on the 
Open House can be read in the Tith 
or can be obtained from your Engi- 
neering Council representative. 

Have you decided what you'd like 
to do after you leave Alma Mater? In 
case you haven't quite made up your 
mind, the Engineering Council, in co- 
operation with other councils on the 
campus, has some news that you'll find 
interesting. Right here we'll mention 
the dates: December 5, 6, 7, and H. 
Don't forget them ! 

Wondering what's so important that 
\()u shoiddn't overlook? It's called the 
Career Conference and that's exactly 
what it's going to be: a conference on 
careers. 

Some of the most important men in 
industry will come here to the Univer- 
sity' to give informative talks on their 
type of work. One of the major aims 
is to acquaint the students with the va- 
rious fields, and as we said before, if 
you haven't made a choice \"et, this is 
.something you can't afford to miss. 
Everyone will find that one of the 
talks will be something he wants to 
hear. 

If you're a freshman in Commerce 
or a senior in Engineering, there'll be 
a talk for you ; and if you want to hear 
them all, go ahead — every one of the 
talks will be interesting, clear, and to 
the point. 



There are a few more deals on the 
fire that \ou won't want to pas^ up, 
and we'll give you the straight info as 
soon as possible. 

It's going to be a busy year for the 
Council but they say the engineering 
outfits have thrown out the word iin- 
[^ussihle — no scientific proof to support 
its use. 

PI TAU SIGMA 

Two members of the Illinois Alpha 
Chapter of Pi Tau Sigma, Joseph T. 
Ream and Donald R. Tarne, attended 
the annual national convention of this 
Mechanical Engineering honorary fra- 
ternity which was held this year, Octo- 
ber 20 through 22, at Lehigh Univer- 
sity, Bethlehem, Pennsylvania. 

Representati\es from all 41 different 
chapters throughout the nation were 
present to discuss the past year's activi- 
ties and make plans for the coming 
year. 

M.I.S. 

The Mineral Industries Society start- 
ed the semester this fall with their an- 
nual student-facidty smoker which was 
held last month. 

At another gathering in October, Dr. 
William C. Robb, Assistant Dean of 
the College of Commerce and Business 
Administration, gave a talk on the Taft- 
Hartley law and its repercussions today 
on labor and management. The MIS 
likes to keep pace with the world today. 

The exact line-up for the semester is 
still a little in doubt, but there'll be 
a meeting on the second Wednesday of 
e\ery month. In the way of business, 
the MIS is talking over the plans for 
the Engineering Open House and the 
Career Conference. Mighty Industrious 
Society. 

A.S.M.E. & S.A.E. 

The ASME and the SAE combined 
their many talents to make a big suc- 
cess of their 'Tirst Xighter." If attend- 
ance at the smoker, October 6, is indica- 
tive, the gears will really be turning 
over this year. 

John Menees, president of the 
ASME, presided and introduced offi- 
cers and advisers of both student chap- 
ters; he also introduced the two guest 
speakers of the evening, N. A. Parker, 
head of the Mechanical Engineering 




department, and Dr. William L. Eve- 
ritt, dean of the College of Engineer- 
ing. 

Professor Parker, in his talk on "The 
Engineering College Viewpoint of the 
Engineering Council and Societies," 
brought to the fore some of the past 
of the Council. He proposed the form- 
ula: S = AIM -\- E. Literature students 
would better understand this as: Suc- 
cess equals a knowledge of Materials, 
Machines, Methods, and Man. plus En- 
ergy. 

Dean Everitt included a bit of re- 
ligious philosophy, as well as plenty of 
wit, in his talk about "The Importance 
of the Engineering Societies to the En- 
gineering Students and Graduates." 

A.I.E.E.-I.R.E. 

The electrical and radio engineers 
got under way this fail with a meeting 
on October 4. Dean Everitt, dean of 
the College of Engineering, and Dr. 
Ryder, head of the E.E. 
department, were present 
as guests. Most of the 
business talked over that 
night revolved around St. 
Pat's Ball. A vote was 
taken as to whether the electrical show 
shoidd be held at the same time as the 
Ball, but the results of the poll have 
not been reported. 

I.LE. 

If you should happen to see a student 
standing calmly in the middle of Green 
street inviting almost certain death, just 
forget it. It's probably one of ITE's 
boys — a traffic engineer, that is. Any 
time that you can't find a place to park 
your car, give them a call and they'll 
tell \ou all about it. 

At their last meeting on October 24, 
the traffic engineers had Professor 
Wiley, a member of the ITE national 
chapter, and Professor Danner, high- 
way engineer, as guests. Professor 
Wiley gave a talk entitled "Traffic En- 
gineering and the Future," and members 
discussed a survey on parking at the 
University. Along that same line, an- 
other subject of interest was an e\alua- 
tion of the parking lots now in use and 
the possible sites of new ones.

CHARLES K. JANKOWSKY 

Charles Jankowsky was born in the 
cement city, Oglesby, IHiiiois, and at- 
tended school in Minonk. Upon gradu- 
ation from high school in 1934, he went 
to work for the CCC at Galva, Illi- 
nois. In 1037, he went to Washington, 
D. C, to spend a year with the Carto- 
graphic unit of the Soil Conservation 
Service. He spent the years between 
1938 and 1942 with the U. S. Engi- 
neers in Little Rock, Arkansas, work- 
ing on soil conservation projects in Ar- 
kansas and Missouri. 

April, 1942, found Jankowsky in 
Uncle Sam's armv. With the 15th Air 




CHARLES K. JANKOWSKY 

Force in Africa and Italy, he was a 
bombardier on a B-17. Following serv- 
ice, in November, 1945, he went back 
to his job at Little Rock. He soon 
found that he could advance no higher 
among the engineers without a college 
degree, so he decided that the next thing 
would be a college education. 

Jan, as he is often called, entered 
the University of Illinois in September, 
1946. Because of his experience in soil 
conservation, he considered Agricultural 
engineering, but he decided upon petro- 
leum production and later switched to 
Mining engineering, in which he will 
graduate in Februar\'. Charles found 
college a little difficult at first, after 
being out of school for 12 years. How- 
ever, by the second semester, he was 
working 52 hours a week besides going 
to school. 

Jankowsky prefers rolling land to the

flat plains of Central Illinois. He does 
not have a job yet, but would be inter- 
ested in almost any type of mining. He 
is a member of MIS and a student asso- 
ciate of AIMF. He was married last 
January. 

PROF. D. G. CARTER 

Last year Deane G. Carter, profe.ssor 
of farm structures, received his profes- 
sional degree of Agricultural Engineer, 
awarded by the University of Illinois. 
This was the first and, so far, the only 
degree of this type. 

Born in Missouri, Mr. Carter attend- 
ed Iowa State College, where he re- 
ceived his B.S. degree in 1915. He spent 
about two years with Jamesway, a farm 
building equipment manufacturer, and 
three years on the staff at Iowa State 
College. The next year, 1919, he or- 
ganized a department of Agricultural 
Engineering at North Carolina. Mr. 
Carter was head of the Agricultural 
Engineering department at the L^niver- 
sity of Arkansas from 1922 to 1941. 
He came to Illinois in 1941. 

Professor Carter is a member of Tau 
Beta Pi, Alpha Zeta, Sigma Xi, and 
Gamma Sigma Delta. He has written 
two books. Farm Buildings, with W. A. 
Foster, and Faiiiily Housing, with Keith 
H. Hinchcliff, both of which are ac- 
cepted as standard college texts. 

He has served as a consultant on rural 
construction, building design, and hous- 
ing, and as a collaborator with various 
government agencies. Dr. Carter is 
chairman of the Research committee on

Farm Housing for the North Central 
states. 

His interests in students is shown by 
his work on the graduate program in 
Agricultural engineering, and by his per- 
sonal counseling and aid in the registra- 
tion of students in the Agricultural en- 
gineering cirruculum. 

GIRARD GOLDEN 

(lirard (iolden is a man worth meet- 
ing and getting to know well. He is a 
chemical engineer in his last semester. 

Not to be content with a mere B.S. 
degree, he plans to continue his studies 
and obtain a Ph.D. From the looks of 
his 4.5 average he will have no trouble 
in fulfilling this ambition. After that 




GIR ARI) GOLDK.N 

he will be interested in the production 
phase of chemical engineering work. 

Back in '44, about two weeks after 
graduating from high school, Girard 
joined the army reserves and went to 
Princeton L^niversity under the A- 12 
plan. F"ollowing a year and a half there 
and five months of regular army duty, 
he attended the North Carolina State 
College for one semester. He was dis- 
charged in October of '46 and came 
to this great institution of learning the 
following February. He was a member 
of the Newman club for a year and is, 
of course, a student member of the 
A.I.Ch.E. 

Girard's father is an insurance and 
real estate salesman in Rochester, N. Y. 
A younger brother has also chosen the 
engineering profession and is studying 
at Alfred University in New York. 

Despite the fact that Girard is an 
engineer and has been in the upper 
three per cent of his class for two years, 
he is not an intellectual bore. Gifted 
with an engaging personality, Girard is 
a very eligible bachelor.

The student chapter of the American 
Society of Civil Engineers had as speak- 
er at its first meeting in October Mr. 
R. Salter, an outstanding engineer, 
working with the city of Chicago. Mr. 
Salter was formerly the .society's repre- 
sentative in the Midwest. He chose as 
his topic, ''Filtered Water for Chi- 
cago." 

At a business meeting held recentlw 
the following men were elected to of- 
fice : 

President, Stan Cjerut; Secretary, N. 
Harano\ich ; (Outside Representative, R. 
C. King; anil Social Chairman, Dale 
Carr. 

The society also set up a fall program 
of eight meetings for the coming school 
year, in addition to the usual social 
events. 

A scholarship of fifty dollars, offered 
last year by the society, was awarded 
to \like Whittington and Bob King. 
The checks were pre.sented to these men 
at camp where the money came in 
haiuiv. 




Mike Whittington and Bob King 
were at summer surveying camp 
when their A.S.C.E. scholarship 
checks were presented to them.

discussed and future plans made. On 
October II the society held its second 
meeting which consisted of a movie and 
general business. Tentatively, four field 
trips to various concerns in the Chicago 
area are being planned by the field trip 
committee. 

The group of new officers consists of 
Irving H. Hallberg, president; Leon C. 
Hummel, vice-president; J. Roy Wil- 
helm, treasurer. They are planning as 
full a program as the society experienced 
last semester.

This is for YOU! 



On December 5, 6, 7, and 8, the first annual Career Conference will be pre- 
sented at the University of Illinois. The purpose of this Conference is to give 
YOU a complete first-hand account of industrial and professional occupations. 

Speakers from nearly all fields of endeavor, fully representing the University 
colleges and schools, will be on the campus during the Conference week to give 
YOU precise information about vocations that YOU may be interested in. These 
speakers will be the men most capable of informing YOU about careers. They 
have been recommended by the deans of the various colleges and the heads of 
departments. Sixty-four prominent men have been contacted, and many of them 
have responded with interest and a desire to help in this very worth-while 
Conference. 

Each speaker will inform you of the complete career situation in his respective 
field. The following items will be included in his talk: 



1. Job opportunities 

2. Promotional opportunities 

3. Preparatory training 



4. Specialization 

5. On-the-job training programs 



The idea for this Conference was originated about two years ago by Phi Eta 
Sigma, Freshman men's honorary, and the YMCA. It has been in the process of 
development and organization since that time. With the advice of the YMCA 
and the approval of the deans of the colleges, University funds were secured 
for the presentation of the Conference this December. 

The administrative work for the Conference is being done by students of 
the following organizations: 

Engineering Council, College of Engineering 
Commerce Council, College of Commerce 
L.A.S. Council, College of L. A. & S. 
Junior Bar Association, College of Law 
Journalism Forum, College of Journalism 
Education Forum, College of Education 
Agricultural Council, College of Agriculture 
Phi Epsilon Kappa, Physical Education School 

Remember, you slipstick shuffler, you electrician, you grease 

monkey, and you, too, plumber! YOUR career will be better 

because of the Career Conference

"The L niversit\' assumes no responsibilit\ 
for accidents that may occur." A sign bearing 
these words of warning gently reminds you 
to be careful around the furnace in the 
foundry. 

Suppose that on the morning of October 
22 you were standing within five feet of this 
sign, but burned a finger despite its warn- 
ings. You would have descended 10 feet of 
stairs, and walked, or ran, at least 60 feet 
to a first-aid box. It is assumed, of course, 
that you knew into which dark corner to look, 
so that vou could go directly to the first- 
aid cabinet. 

After opening the door of the dirty case, 
you found : 

1 bottle — spirits of ammonia 
1 bottle — green soap 
1 bottle — aluminum acetate 
1 bottle — 3% iodine 
1 1 applicator swabs 
1 enameled pan 
1 box cotton 
1 tourinquet 
4 rolls gauze bandage 
6 gauze compresses 
tape. 

What did you do? Start throwing on bot- 
tles and bandages? Run over to the Health 
Center and wait for treatment? Say "Nuts" 
and go back to work at the furnace? 

Had your intuition worked miraculously 
(or if you were a good Boy Scout), you 
would have used the aluminum acetate solu- 
tion. Then you would have looked for a pic- 
ric acid compress to tape over the burn; and 
you woulii ha\e received proper first-aid treat- 
ment. 

However, if the aluminum acetate failed 
to jump into your hand when you opened 
the door, you would have received absolutely 
no hint that it was intended for burns like 
yours. 

The label on the ammonia bottle said, 
"dilute, 1 teaspoon to 10 teaspoons water." 
(\V"ho wants to fuss with teaspoons in an 



emergency?) The iodine was in a clear white 
bottle without the customary POISON greet- 
ing. Of the 11 applicator swabs, four were 
protected and clean, four were open and ex- 
posed to the dirt, and three had been used 
once and were waiting for a second time 
through. The cotton box was open, tape sup- 
ply was insufficient, and the picric acid com- 
presses had recessed. The tourinquet carried 
the dangerous directions, "twist until bleed- 
ing stops." The enameled pan? ... it must 
be pro\ided to keep the blood from dripping 
onto the floor! 

Twenty first-aid boxes throughout the en- 
gineering campus were checked on the event- 
ful day that you binned your finger. All were 
dirty by the "white glove" test. Xo mice ran 
out of the corners, but the cabinets were 
about that sterile! Seven used applicators were 
found contributing to contamination. Prob- 
ably seven ungrateful beneficiaries were re- 
sible. Or did they leave their last testimonials 
in the first-aid cabinets? 

In six first-aid boxes the ammonia bottle 
specified dilution before using. If the Health 
Service supplies a uniform concentration to 
all ammonia bottles, there should be uniform 
labels. And it's a bit foolish to put out any- 
thing that can't be used directly. 

Despite the fact that ultra-violet light in- 
creases the activity of iodine, Dr. Beard, di- 
rector of the Health Center, seems to con- 
sider clear white bottles good enough to con- 
tain the iodine in the first-aid cabinets. Ap- 
parently others ha\e different opinions, be- 
cause it is sold m brown or blue bottles. 

According to Dr. Cireenwood of the Health 
Center, green soap is good for wounds. Sev- 
eral of the bottles say the opposite ; some say 
"for external use only"; some say "poison." 
Maybe the color (green to yellow to red) 
doesn't matter, but the label does! Is it or 
ain't it? 

All bottles that arc poisonous should he 
labeled POISON. One of these days we'll 
hear of someone taking ammonia to cure an 
acid stomach !

The first-aid boxes are not plainly marked; 
the white cabinets don't stand out from the 
usually yellow walls. In the new IVI. E. build- 
ing there is no distinguishing marking what- 
ever to tell you what lies behind those mir- 
rors in the corridors. A mirror on a first- 
aid cabinet is all in the bathroom, but in 
the corridors, safety, rather than vanity, 
should be the objective. (This is no fault of 
the Mechanical Engineering department. 
They merely requisitioned the Health Cen- 
ter to install the cabinets and did not not 
choose the style.) 

In the new E. E. building the contents 
can be seen, but the cabinets are set back into 
the walls. Thus they can't be easily identified 
from afar. 

Only in Talbot lab was any semblance of 
first-aid instruction found. A small card on 
the door of each cabinet gives specific di- 
rections for using each of the materials inside. 
Most of the equipment was fresh and clean 
— and the green soap \^•as green. 

First-aid treatment for burns seems to be 
particularly lacking in the metal heat treat- 
ment laboratory and the ceramics kiln room. 
Apparently burns are not uncommon in the 
former — the aluminum acetate bottle outside 
the heat treatment lab was empty. It takes 
almost a 100-yard dash from the kiln room 
to get to the butesin picrate in the Ceramics 
building. 

And then there is the Chemistry depart- 
ment. Hats off for a first-aid cabinet in every 
student laboratory. But Dr. Roger Adams 
can eat 'em, feathers and all, 'cause the cabi- 
nets are locked. 

Why, Dr. Adams, ichy? Do chemistry stu- 
dents know less about first aid than others? 
Are the key-carrying instructors given spe- 
cial instructions? Would the chem students 



steal the contents? . . . then why isn't the fire 
blanket in 250 Noyes locked up too? Or 
would the first-aid supplies be used up too 
fast if everyone could easily get his own treat- 
ment? 

Last spring three students went to Mc- 
Kinley hospital from Organic lab, Chem 237. 
Yes, the instructors were on hand when each 
of the accidents happened ; but it would often 
be faster to run down the corridor to the 
"free" first-aid station than to run over to 
Nick's to get the instructor. 

pLirthermore, the Health Center recom- 
mends no locks; and they won't fill the bot- 
tles unless specially requested by the depart- 
ment. 

The svstem for maintaining the first-aid 
stations is almost a pass-the-buck affair. About 
every two weeks the Health Center sends 
out someone to fill the bottles; standard first- 
aid equipment is used throughout. However, 
each department has to requisition for any 
items that might be missing or that need re- 
placing. 

Hut how do they know if ,i bottle of iodine 
needs replacing? The\' usualh' don't! Xo bot- 
tles are dated when installed or when filled. 
(They don't even know when to celebrate 
the first anniversary!) It seems that no peri- 
odic check is made on the quality of contents. 
The green soap coidd turn back to green, the 
aluminum acetate could precipitate out, and 
ammonia could blow its top; or "will it take 
.leath?" 

The Health Center anil the ilepartments 
shoidd either define the obligation or make 
plans for better cooperation. Let's make the 
first-aid .stations shout! Let's provide correct 
labels and directions for usage, and keep tabs 
on the filling dates! And, please, let's open 
the doors, Roger! — R.L.H.

acid to the ghcerine before it was used. 
The result of the investigation produced 
what are called the modified glyptals 
which find wide usage in paints and 
coatings. 

In V:)19 Dr. Fritz I'ollak began a 
detailed investigation of the plastics that 
might be obtained through the use of 
urea and formaldehyde. The real ob- 
ject of his search was a substitute for 
glass but he was unsuccessful in this 
endeavor. 

He did show, howe\er, that the plas- 
tic obtained from the reaction could be 
used as a molding powder when suitable 
fillers were employed. The products of 
the reaction were thermosetting and 
some manufacturing of them was started 
in 1924. Dr. Pollak's work showed, 
moreover, that the amino-plasties could 
be used successfully; a few years later, 
another famous man in plastics was to 
show just how successfully. 

'J'lni/iirj/>lfistir Fo/y /Iters 

From the beginning of plastics in 
lSf)5 until 1929, the bulk of the re- 
search carried out produced only ma- 
terials which were thermosetting. It was 
in that dark year of the "Big Crash" 
that a new type of plastic appeared ; 
rather than hardening when heated, it 



remained soft and pliable. This new 
line of research was carried on in (ler- 
many, at first, and a few years later in 
the L'nited States. The subject of the 
investigations was the polymerization of 
styrene which yielded a material called, 
appropriately enough, polystyrene. 

The rciction involves connecting the 
molecules of styrene together; and 
though there are many catalysts that 
may be used, heat alone is sufficient. 
The long chains are formed as in the 
thermosetting compounds, but little or 
no cross-linking occurs. As a result, the 
plastic does not get harder when heated. 
This is a characteristic of the thermo- 
plastic materials. In many cases, the 
high molecular weight compound ma\ 
break down into the individual mole- 
cules when heated. 

A casual glance through most of the 
large circulation magazines will yield 
a number of advertisements for items 
made of polystyrene. Two of the more 
prominent names used commercially are 
Lustrex and Styron. Kitchen utensils, 
wallboard, and toys are among the most 
familiar products molded of polystyrene 
but the list of things made from it is 
growing every day. 

Soon after the work on polystyrene, 
research was conducted on the polymeri- 
zation of methyl methacrylate. The 



tradenames under which this material 
appears on the market are Plexiglas and 
Lucite; and in F'ngland, the same thing 
is called Ferspex. Mentioning the 
things that bear one of those names 
would be stating the obvious. Plexiglas, 
of course, will be remembered as the 
material used in the "windows" of air- 
planes. 

The polyvinyl compounds were de- 
veloped after plexiglas and are known 
conimnnly under the trade name of Vi- 
nylite. There are, however, many differ- 
ent forms of the tough vinylite plas- 
tics; this is also true for most of the 
plastics. 

The vinyl polymers pop up all over 
the place. That chair in the corner may 
be covered with a vinyl plastic uphol- 
stery material ; one form of vinylite gets 
trampled upon all the time, perhaps 
the lawn hose is made of vinylite ; that 
shower curtain upstairs may well be 
made out of vinyl plastic. It's a job try- 
ing to avoid the stuff and there's a rea- 
son. The plastics hold up better than 
anything else. 

While on this particular group of 
polymers, a word must be said about 
one of the relatively new ones. The 
polyethylene plastics made their debut 
on the market about 1939. One of the

W orld's fastest automatic changer— in RCA 45 rpm system- 
changes records in 5 seconds. 



^^/^/^ c/?a/7^e a/t/s6 



Hundreds of thousands are now enjoying 
RCA's thrilling new way of playing rec- 
ords . . . they marvel at its wonderful tone 
. . . and the speed with which it changes 
records. 

Prolonged research is behind this achieve- 
ment, research which sought — for the first 
lime in 70 years of phonograph history — a 
record and automatic player designed for 
each other. 

Revolutionary is its record-changing 
principle, with mechanism inside the cen- 
tral spindle post on which records are 
so easily stacked. Result: a simplified 
machine, that automatically changes rec- 
ords in 5 seconds. 

Remarkable, too, are the new records — 
only 6Tb inches in diameter— yet giving the 



playing time of conventional 12-inch rec- 
ords. Unbreakable, these compact vinyl plas- 
tic discs use onlv the distortion-free "quality 
zone". . . for unbelievable beauty of tone. 

\'alue of the research behind RCA's 45 
rpm system — which was started 1 1 years 
ago at RCA Laboratories — is seen in the 
instant acceptance, by the public, of this 
better way of playing records. Music 
lovers may now have both the 45 rpm 
system, and the conventional "78." 



Development of an cntirchj new record-play- 
ing principle is just one of hundreds of ways 
in tchich RCA research works for you. 
Leadership in science and engineering adds 
\alue be\(>nd price to any product of RCA,

Syiilhftir Rubbers 

Technically speaking, the synthetic 
rubbers should not be classified as plas- 
tics. They are considered as such, how- 
ever, because of their similarity tliroufili 
the process of polymerization h\ which 
they are made. 

The first reported work done in tlu' 
field was that carried out in 1890 b\ 
a man named Tilden. He obtained a 
rubber-like material by treating isoprene 
with sodium metal but this appears to 
be as far as anvone went with this field 
of research. 

It was not until the first Worhl War 
that (lermany turned her full attention 
to the problem of finding a substitute 
for natural rubber. They were forced 
into this action since the Allies had sev- 
ered the rubber supply route. The stop- 
gap material that was fiiialh obtained 
and used involved the treatment of buta- 
diene with sodium metal. 

The synthetic resulting from the re- 
action was highly unsatisfactory and 



after the war there was apparently no 
extensive research carried out; {Germany 
returned to the use of natural rubber 
when it was once again a\ailable to 
them. 

In I ').?(), however, the Ciermans again 
tackleil the problem of synthetic rubber; 
this time they would not be caught off 
guard as they were in the first war. 
The result of this research was Buna 
S which is made by the co-polynieri/,a- 
lion of butadiene and styrene. .Mean- 
while, the I'nited States carried out 
only limited iiuestigations of the prob- 
lem of a natural rubber substitute. 

In I'Hi, we woke up one moijiing 
and found ourselves cut off from the 
rubber suppl\' of the East Indies by the 
Japanese. Work was started at a fever- 
ish pace and through a major chemical 
engineering feat we succeeded in pro- 
ducing 800,000 tons per year before 
the end of the war. 

We now have available a new prod- 
uct called cold rubber that will gi\e 
longer and better wear than natural 
rubber. 

Kylon 

No discussion of plastics would be 
complete without reference to the bril- 
liant work done by Dr. W. H. Ca- 
rothers and his assistants. Dr. Carothers 
began his detailed investigation of ther- 



moplastics in 1927. In the course of his 
research he discovered cold drawing, and 
his fibers were the first truly synthetic 
material e\er produced. The mention of 
his name immediately brings to mind 
the name "nylon." It should be noted 
that the name does not mean that all 
the nylon products are the same thing. 
There are different types of nylon fi- 
bers, depending upon the use to which 
the final product is to be put. 

The list of items made out of some 
form of nylon is practically a book in 
itself, so just a few will be mentioned. 
To the feminine creatures on the cam- 
pus, the name nylon means hose that 
wears and wears and wears; it also 
stands for one of the latest accomplish- 
ments: dresses that can be washed in 
the sink, dried in an hour, and worn 
as .soon as they are dry. There's no 
ironing required even if the dress has 
a lot of pleats! 

Of course the men get something out 
of this amazing material, too. There are 
nylon shirts that dry in little or no time 
and don't need be ironed ; and there are 
socks that wear like iron. Nylon cargo 
nets and tow ropes are in use ; not only 
are they longer lasting but they're 
stronger than steel cables. The Air 
Force used nylon ropes to pick up and

THE TECHNOGRAPH 




Let's get down to earth . 



Imagine stealing three billion tons of earth every year! 
That's what soil erosion has been doing. And this gigantic 
tlicft has cost farmers billions of dollars. For good earth is 
riol dirt cheap. 

"Stop erosion!" has become the farmers' war cry. Agri- 
cultural agencies have joined the farmers. Together, they 
have turned to the farm machinery makers. They've asked 
for bigger and better bulldozers, tractors, graders for neces- 
sarv ditching and terracing. But to build this super farm 
machinery takes tougher steel, new alloys. 

Here is where UCC enters the allied offensive against 
erosion. Drawing on its vast engineering experience, UCC 
contributes modern metallurgical techniques and alloys. 
This co-operation widi steel manufacturers helps the farm 
machinery makers . . . who then are able to give the farmers 
the equipment they need. 

How is the "war" going? The farmers are winning. Dust 



bowls are vanishing. Sterile lands show signs of life. Yes, the 
farmers are winning their fight against soil erosion with a 
combination of new equipment, revegelation and crop 
rotation. 

Union Carbide is proud of its part in this effort. And the 
people of UCC stand ready to help solve other problems . . . 
wherever better materials and processes are needed.

Tliose nylon stockings worn by the 
campus cuties are not fragile little 
things. In a newspaper story recentl\ 
there was the tale about a woman who 
got her car mired in the mud. A passing 
motorist stopped, but neither of the two 
cars carried a tow chain or rope. The 
day was saved when the l.uK's stockings 
were used to tie the bumpers together 
and her car was pulled back onto the 
pavement. 

One of the limbs on the tree has 
been purposely avoided because it isn't 
as strong as might be desired. That one, 
of course, would be rayon. There are 
many articles of clothing made out of 
rayon but the material is not too satis- 
f.ictory. Most of the rayon fabrics are 
actually a combination of two or more 
plastics as th<' ad\ertiscnients often say. 
It is. none the less, an important de- 
velopment. 

In the course of the tree-climbing, 
only the more important branches have 
been investigated. There are many, 
manv more that could have been. How- 



ever, it's a very large tree ; and it will 
continue to grow, though not as rapidly 
as it has in the past few years. The 
possibilities in the fielil of plastics are 
almost unlimited. The way things are 
going now, that old commercial saw 
abo\it not accepting a substitute will 
h;i\e to be changed to something like: 
"If it can be made out of plastic, don't 
accept the natural thing." 

A famous company put it in ,i few 
wortls that are an appropriate ending 
to thi> climb: "Better Things foi Bet-

State's Attorneys of violators of these 
laws. One of the objectives of the 
N.S.P.E. Legislative committee has been 
to bring about a uniformity of these 



laws, which vary widely from state to 
state, through a Model Registration 
Law. 

Wh.'it does a student do to become 
registered? Man\- states follow the same 
registration code that Illinois has: a the- 
oretical examination given immediately 
after graduation from an accredited en- 
gineering school ; a training period in 
the professional field of four years or 
more; and, finally, a practical examina- 
tion. Examinations are given two times 
a year, in May and December. 

N.S.P.E. is still a very young organi- 
zation; but in time, it is hoped, will in- 
clude nearly all of the nation's engi- 
neers, for it is only in unity that the 
professional engineers will give the 
greatest service to society and receive 
their due public recognition and estee:ii. 

Additional information about the Illi- 
nois Society of Professional Engineers 
and the registration examinations can

New head with a good idea 

Designers of a new milling head had a precision 
problem. They had to give the head a high degree 
of accuracy that would last even under the toughest 
loads. They answered the poser with Timken" 
tapered roller bearings — on spindle, pinion and 
gear shafts. 

Timken bearings keep the shafts rigid and accurate 
under heavy radial, thrust and combination loads, 
eliminate deflection and end-play, reduce wear on 
moving parts. 





TIMKEN bearings do 
9 out of 10 jobs better 

Nine out often bearing applications can be handled 
more efficiently by Timken bearings. Some of the 
reasons why: they carry radial and thrust and com- 
bination loads; line contact between rolls and races 
means greater load capacity; positive roller align- 
ment, true rolling motion, and microscopic accuracy 
make them almost 100^ frictionless; they permit 
pre-loading to any desired degree. 



Want to learn more 
about bearings? 

Some of the important engineering problems you'll 
face after graduation will involve bearing applica- 
tions. If you'd like to learn more about this phase 
of engineering, we'll be glad to help. For additional

neers use them, write today to The Timken Roller

THE DU PONT 

DIGEST 



FOR STUDENTS OF SCIENCE AND ENGINEERING 



yarn 
from 
corncobs! 



A DU PONT PROCESS CONVERTS 

FURFURAL INTO A CHEMICAL 

FOR MAKING NYLON 

One of the fascinating things about 
nylon is the unhkely sounding raw 
materials that go into it. Popu- 
larly, nylon is said to be made from 
coal, air and water. This is because 
originally, in developing its chemi- 
cal intermediates, chemists used ben- 
zene (from coal), ammonia (from air 
and water), and oxygen (from air). 
But Du Pont is always looking for 
new ways of doing things. After the 
discovery of nylon in 1934, research 
men immediately began looking for 
alternative ways of making the two 
main intermediates — adipic acid and 
hexamethylenediamine. In 1935, 
when nylon was still in the labora- 
tory stage and three years before its 
commercial debut, they started work 
on the possibility of using furfural 
in the process. 




Furfural has been used in the chem- 
ical industry for 25 years, but it is 
little known to the layman. A tan- 
colored liquid with a faint bitter- 
almond odor, it is made from a wide 
variety of agricultural by-products. 
Among these are corncobs and hulls 
ofcottonseed, oats, rice — allavailable 
in practically unlimited quantities 
from America's farms. 




A. G. Sveinbjornsson, Ph.D., Organic Chem- 
istry, University of Kansas, 19-48, and H. B. 
Copelin, M. S., Organic Chemistry, Cornell, 
1941, studying new furfural derivatives. 



C. R. Dewey, B. S. Chem., Niagara Unnvr- 
sity, 1941, and J. M. Estes, B.S. Ch.E., Uni- 
versity of Missouri, 1937, engaged in produc- 
tion of adiponitrile at the Du Pont Electro- 
chemicals plant in Niagara Falls, New York. 



14 Years of Research 
and Development 

It seems a far cry from corncobs to 
nylon, and it was. The development 
from the first small-scale laboratory 
experiments to the present full-scale 
plant cost 14 years of time and about 
five million dollars. But it enabled 
chemists to produce large quantities 
of adiponitrile, the compound from 
which hexamethylenediamine is 
made, by an economical process 
which uses natural materials that 
are in continuous supply. 

In the new process, furfural is con- 
verted by a series of steps to 1,4-di- 
chlorobutane. The next step explains 
in part why Du Pont undertook the 
project in the first place. As pro- 
ducers of cyanides, they had sodium 




Scale model of a part of the Du Pont adiponi- 
trile plant at Niagara Falls. Here furfural, an 
agricultural by-product, is converted into a 
chemical intermediate for making nylon. 



cyanide available for converting the 
1,4-dichlorobutane into adiponitrile. 
The final product, hexamethylene- 
diamine, is then reacted with adipic 
acid to make nylon "salt." Still more 
processing and the salt becomes yarn, 
and the nylon flake used by the 
plastics industry. 

Opportunities at Du Pont 
in many scientific fields 

This is an excellent example of the 
interesting work in industrial organic 
chemistry carried on at Du Pont. It 
required the technical knowledge and 
skill of highly trained research and 
development men, including organic 
and physical chemists; chemical, me- 
chanical, civil and electrical engi- 
neers, and others. 

Only a large company with ample 
resources in men and money could 
afford to engage in research of such 
magnitude. To the young college 
graduate, Du Pont offers the broad- 
est of opportunities in many scientific 
fields, along with the advantages of 
working directly with a small group 
of associates. 

Keynote of Du Pont personnel 
policy is promotion from within on 
a competitive merit basis. A con- 
scientious effort is made not only 
to choose college-trained people of 
promise, but to develop each indi- 
vidual as rapidly as possible.

PROBLEM — You are designing an automobile 
service car with a crane on the back end. You 
are going to take power from the transmission 
to drive the crane drum. How would you do it? 

THE SIMPLE SOLUTION — Use an S.S.White 
power drive flexible shaft. Connect one end to 
a take-off on the transmission and the other end 
to the clutch which operates the crane drum — 
simple, easy to install, good for positive, de- 
pendable operation.

SILICONES . . . 

(Coiitiiuieii from p:ij;c S) 
piT molecule. The outstaiidiiiK prop- 
erties of silicone oil are nearly con- 
stant high viscosity over a very wide 
temperature range; resistance to o\icia- 
tion ; and water repeilencN'. 

Damping vibrations has been one (jf 
the most important uses of these oils. 
In this respect, the fluids are used in 
delicate aircraft instruments, in shock 
absorbers and even in the crystal pick- 
ups of phonographs. In the role of h\ • 
draulic fluids these silicones reliably 
transfer pressure to controlling, record- 
ing and measuring devices from objects 
operating over wide temperature range. 
Some of the other important uses are 
as liquid dielectrics; lubricants, especial- 
ly for plastics and rubber which are un- 
stable towards ordinary lubricants ; re- 
lease agents; and as coatings and im- 
pregnants. 

(jreases are formed by increasing the 
length of the silicone chain (and hence, 
the \iscosit\). The outstanding property 
of these greases is the nearly constant 
\iscosity throughout a tremendous tem- 
peratine range: from — 10° C to well 
over 200° C. Certain of these greases, 
such as stopcock grease and high vacuum 
grease, find their uses in laboratories. 
Other special greases have been devel-

temperature lubrication (350° F). One 
can be used in bearings operating at 
20,000 rpm at temperatures ranging 
from -95° F to 300° F. 

Diverse Functions 
The development of totally enclosed 
("explosion proof") electric motors 
and transformers is largely due to sili- 
cone greases, and silicone binders and 
varnishes. The introduction of "fiber- 
glass" increased the operating tempera- 
tures of motors, but the organic var- 
nishes which had to be used to bind the 
fibrous glass still limited the operating 
temperatures. The silicone varnishes not 
only overcame this limitation but also 
rendered the motor water-repellent. An- 
other important factor is that a 10 hp 
totally enclosed motor using this type of 
insulation is the same size and weight as 
a regular 3 lip motor. 

There is a wide \ ariety of household 
uses for silicone and silicone-treated ma- 
terials. On every drugstore counter one. 
notices small booklets that brightly : 
nounce that they are "Sightsavers." This 
lens cleaner is a silicone-treated tissue. 

Another silicone material which falls 
into this category- is a silicone com- 
pound known as DC Pan Cjlaze. In 
many bakeries all over the country, DC 
Pan Glaze is now being used in place 
of shortening as a release agent for

Silicone rubber is a material which 
has found extensive use in industr\- be- 
cause of its heat resistance ( — 70° /' to 
.ibove 325° F), chemical stability, elec- 
trical properties, and compression char- 
acteristics. It is used chiefly for gaskets 
and as a heat seal. In this way the rub- 
ber is used on turbo-jet engines, ovens, 
>earchlighrs, chemical process equipment, 
and insuhition for electric wires. 

A silicone which has found extensive 
use in the bottling industries is DC 
Antifoam-.:/. Suppressing foam during 
bottling and many other processes saves 
a great deal of time and material. This 
silicone, though more expensive than 
other foam suppressors, is still economi- 
cal. 

One of the earliest uses of silicones 
was the direct application of (CH.,).,-

to be treated is moistened and then 
placed in contact with the gaseous di- 



methyl-dichlorosilane; and within a few 
minutes, the (CH-J.^SiCh. is hydrolyzed 
and polymerized to form a surface of 
high electrical leakage resistance which 
is also water repellent. Many ceramic 
surfaces, steatite parts, vvindshielils and

Making the ^^ juice ^^ that makes life easier! 




DIRECTLY and indirectly, the average 
family in America consumes more 
electricity yearly than families in any 
other country in the world. The demand 
for more "juice" has grown with un- 
helievable rapidity, and it's still grow- 
ing. By 1955, the electrical generating 
capacity of our nation is expected to 
reach 90 million kilowatts! 

Steel is a vital material in the pro- 
duction of electricity. Central power 
stations and great power dams are made 
of steel and concrete. Special steels are 
required for turbines and other genera- 
ting machinery. Steel towers carry 



steel-reinforced transmission lines across 
mountain and prairie alike. 

Helping to meet America's constantly 
growing demands for more "juice" is 
only one of the big jobs ahead for United 
States Steel. There are many others. 
And they all call for the services of 
thousands of carefully-trained, technical 
specialists. For steelmaking today is a 
precision operation, as dependent for 
success on the knowledge of metallurgi- 
cal, mechanical, chemical, electrical, min- 
ing, civil and ceramic engineers, as upon 
the plant workers themselves. 

To assure employees opportunity for 



ma.ximum personal development and 
provide a sound foundation for advance- 
ment in the organization are fundamen- 
tal objectives of U. S. Steel. Employees 
participating in educational activities of 
U. S. Steel comprise a group exceeded 
in size only by the student bodies of a 
few of the nation's largest universities. 
In these educational programs, partic- 
ular attention is given to the develop- 
ment of college graduates and other 
technically trained men. 

For men who can qualify, a career 
with United States Steel offers a prom- 
ising future.

How many 

Dimensions 

has a 

Name? 




When you measure a name, there are many 
"dimensions" to consider, such as: integrity, 
capacity, vision, strength and skill. These 
qualities constitute a yardstick for professional 
and public recognition. 

There will be many times in your career 
when you can increase the "dimensions" of 
your name by the development of a product, a 
method or through a decision you make. 

Some idea of the dimensions of the name 
Westinghouse, for example, may be gained by 
a few facts about one of its many activities . . . 
building turbines. 

In this field is the Westinghouse J-34 jet 
engine which is setting a new pace in aircraft 
propulsion in the much-discussed Navy "Ban- 
shee" and the Army Lockheed F-90, as well as 
in many other airplanes of both services — as 
yet unannounced. 

Such developments require a rich back- 



ground of experience, technical knowledge 
and creative skill gained through constant 
search for more efficient, economical sources 
for power . . . qualifications needed to attain 
the eminent position the name Westinghouse 
holds as a leading producer of power equip- 
ment for land, sea and air. 

This is but one of many fields in which the 
name Westinghouse has been indelibly written 
over the years. 

In your career you will measure many names 
and products in industry. As you do, you will 
find the name Westinghouse prominently 
identified with practically every one. 

Whether those products are turbines or 
toasters, locomotives or lamps, electric stair- 
ways or x-ray machines, we will welcome the 
opportunity to share our experience . . . our 
sureness in designing and manufacturing that 
adds a new dimension to a name . . .

new hormone-tvpc chemical related to 
2,4-D. This 2,4,5-T, ixhort for 2,4,5-

Ultra-Violet Microscope 

Designed primarih tor cancer re- 
search, an ultra-violet microscope for 
observing living, mistained body tissues 
is now in production by l^ausch and 
Lomb. 

The instrument's revolutionary objec- 
tives not only provide increased resolv- 
ing power but make it possible to photo- 
graph as well as view freshly prepared 
sections of live tissues and tissue cul- 
tures through three different ultra-violet 
wavelengths. The photographs may also 
be projected or reproduced on color film 
through three visual color filters that 
provide densities, contrast and structinal 
detail ne\er before attained. 



Electronic Tempering 

A tempering proce.ss which heats a 
met.il surface from room temperature 
to a bright-red. 1.600 degrees Fahren- 
heit, ami cools it again to room temper- 
ature, all within less than five seconds, 
has been developed by (jeneral I'dectric 
engineers. 

The process uses an electromagnet 
which holds the part to be tempered 
within the field of a powerful electronic 
heater. 

As soon as the part has been heated 
to the proper temperature, an automatic 
timing switch shuts off the electronic 
heatei'. At the same instant the current 
is removed from the electromagnet and 
the part drops into a cooling bath of oil. 

The process is being used to harden 
the toothed surfaces of small ratchet 
wheels for automatic circuit reclosers. 

Bridge Control System 

A powerful electric ilrive and control 
system, which raises a 1,350-ton bridge 
span 100 feet in 105 seconds, has been 
installed in the recently opened Stickel 




The new Bausch and Lomb ultra-violet microscope will be used for the 
further investigation of cancer tissues. (Photo courtesy of Bausch and

Memori.il Bridge, which crosses the Pas- 
saic River between Newark and Harri- 
son, New Jersey. Power to raise and 
lower the 222-foot vertical lift span is 
supplied by two (^i-E 1 58-horsepower, 
direct current motors, each of which 
moves one side of the span. 

To keep the span level while it is 
being raised or lowered, an "amplidyne 
control system" is employed. In this 
system, .small control units, working 
through a master control device, act to 
vary the speed of the drive motors when- 
ever one end of the span begins to move 
faster than the other. This quickly- 
responsive leveling process begins as soon 
as one end of the span gets a fraction 
of an inch off level. 

Recording Spectro-radiometer 

More cohjrs of light beams than there 
are grains of wheat in Kansas can he 
distinguished by an instrument devel- 
oped by General Electric scientists and 
engineers. 

The color-sensiti\e instrument, known 
as a "recording spectro-radiometer," has 
been designed for use in comparing and 
recording the colors of light sources. It 
breaks up beams being studied into the 
various colors of which they are com- 
posed ; measures the intensities of these 
colors; and makes a permanent record 
of the measurements in the form of a 
graph. 

The instrument draws a curve show- 
ing the distribution of colors in a given 
light source in less than a minute. Pro- 
duction of such curves by methods used 
in the past required a series of long and 
tedious, point-by-point measurements. 

High-Speed Drones 

The shooting eyes of the U. S. Navy's 
anti-aircraft gunners soon will be put to 
the test by the antics of a pilotless, 
radio-controlled, ram-jet-powered Mar- 
tin KDM-1 target drone darting 
through the skies at speed close to that 
of sound. 

A 2()-inch Marquardt ram-jet engine 
will furnish the power for the air- 
launched KDM-1 target. 

The ram-jet engine, sometimes called 
the "stovepipe," has no moving parts. 
A fuel pump used on earlier engine 
models will be replaced by a pressm-ized 
fuel system, eliminating the single mov- 
ing |iart on the first ram-jets.

The liott Power Plant 



Bg Ihin Kvvtf. fli.E. "SO 



A good proi'iiii'r of hc/it and lUcliuity is the Abbott Foiicr Plant. Btsidis 
supplying the University uith plenty of steinn, the facilities make possible a real- 
istic application that is meaningful. Students in the IMechnnical Engineering Ther- 
modynamics laboratory courses run a 24-hour test on the poinr plant's operation. 



Out in the southwest part of our cam- 
pus, where few can see it, is a building 
with a very tall chimney — a building 
that plays a major part in the operation 
f the University. This building is the 
Abbott Power Plant ; it is on Gregory 
Drive next to the Illinois Central tracks. 

From the Old 

In 1936 it became clear that the old 
30wer plant (located near the M. E. 
lab) would not be able to meet the 
requirements of the planned University 
xpansion. The old plant was a two- 
boiler unit when it was put into service 
n 1902. It was enlarged several times 
IS the University grew ; and, in its final 
orni, was a 130-pound operating plant 
lontaining eight longitudinal drum, 
stoker-fired boilers. It had inadequate 
generating capacity and an obsolete 
2,300-volt electrical distribution system. 
As a matter of fact, it had become ne- 
:essary to purchase power from the Illi- 
lois-Iowa Power Company. 

To add to this already unfavorable 
LTondition, the designs for new buildings 
ndicated that there would be a large 
increase in the steam consumption. It 
U'ould have been possible to remodel and 
modernize the old plant, but a survey 
iind report by Sargent Lundy (consult- 
SiiL' engineers) showed this to be inieco- 
liiiinical. 

I To the Neiv 

I Construction of the present-day plant 
was begun in January, 1940, and was 
I'inipleted in February, 1941. It was 
npiiating, however, in parallel with the 
'iM plant as early as September, 1940. 
j Siinie indication of the success of the 
plant is the fact that the operating costs 
|iiropped about 10 per cent, and that the 
>l niversity began selling its surplus elec- 
riir energy during the winter season to 
rill Illinois-Iowa Power Company. 

I he plant is located, as mentioned 
I'li'iie, next to the Illinois Central 
r lacks. This location has two advan- 
t.i'^o: a railroad siding is readily avail- 
ble for the handling of coal in carload 
lots ; and the plant is in a central posi- 
tion for any further expansion of the 
:ampus, which is expected to be toward 
the south. 



Coal handling in the plant is accom- 
plished by a 12' X 14' track hopper into 
which the coal is fed from side- or bot- 
tom-dumping cars. A reciprocating feed- 
er supplies an apron conveyor, and the 
coal may be taken from this point to be 
crushed, if necessary; or it is raised by 
a vertical bucket conveyor to an over- 
head, cross-conveyor, and then into one 
of four Cnuiite-lined, rectangular coal 
bins of 100-ton capacity each. 



Poiccr Production 




At the presnt time, the plant 


use 


three (jeneral Electric .idOO-Z-fr 


tur 



bine-generators to supply power. Two 
of the units are automatic extraction- 
condensing turbines ; and the third is a 
non-condensing unit. All three of the 
turbines operate at 3,bQ0rpin with throt- 
tle steam conditions of 300 psi and up 
to 700 °F total temperature. The three 
generators have the following character- 
istics: 4,160 volts; 3 phases; 60 cycles; 
and 3,000 hv at 0.8 power factor, or 
3,750 kva at unity power factor. 

One condensing unit supplies heating 
steam at extraction pressures up to 70 
jiounds, with exhaust to a 2,500-^?. //. 
."Mlis-Chalmers two-pass surface con- 
denser at 28 in. H g vacuum. The new- 
est condensing unit has a Worthington 
condenser capable of condensing 38,000 
pounds of steam per horn". 

Since the plant is not located on or 
near a plentiful water supply, such as 
a river, the condenser circulating water 
is cooled by induced draft fan cooling 
towers. The water is cooled by the com- 
bined effects of evaporation and direct 
air cooling. Evaporation losses are made 
up from well water which has been pre- 
viously softened by the power plant 
water treating system. 

There are four boilers in the plant. 
Three are Springfield, cross-drum, 
straight tube boilers rated at 80,000 
pounds of steam per hour and a total 
temperature of 700 °F. The other is a 
Babcock-Wilcox, four drum, bent tube 
boiler rated at 80,000 pounds of steam 
per hour, with about the same tempera- 
ture as the Springficlds. It was designed 
for a pressure of 350 psi. and firing is 
accomplished by Habcock-Wilcox chain 
grate stokers. 

One of the plant's biggest operating 

advantages over the old plant is a boiler 

efficiency around 80 per cent. The best 

obtained before was about 65 per cent.

ivork is of interest to anyone u'ho icants to make his home more livdhle. Throuyli 
eoo/>eration ivith research departments of the University and industrial organiza-

tion methods and home desiyn. 



Slightly to the southeast of David 
Kinley Hall stands Mumford House, 
the oldest building on the University of 
Illinois campus and the headquarters of 
the Small Homes Council. Built in 1870 
as a model farmhouse, Mumford house 
reflects the University's early interest 
in architectural research. 

The University of Illinois Sm.iU 
Homes Council was organized in Sep 
tember 1944. Its purpose was to in\ es- 
timate and attempt to solve housing piob 
lems by research into planning and con 
struction methods. The Council was 
founded upon the idea that eventual 
improvement in housing must depend 
upon a general advancement of knowl- 
edge in every type of problem. 

All departments of the University 
whose work is related to housing are 
cooperating in the various projects. To 
these departments, the Council is the 
coordinating agency.

1929, where he has spent 
most of his life. 

He come to Illinois in 
September, 1946, but did 
not become o member of 
the Tcchnograph staff un- 
til this year. He is a 
member of A.S.AE. and 
A.F.S., and is vice presi- 
dent of McKinley Founda- 
tion Student Council. 



The Small Homes Council has been 
headed by William H. Schieck, profes- 
sor of architecture, since its organization. 

Professor Schieck is at present on 
leave from the University to serve as 
the executive director of the newly or- 
ganized Building Research Advisory 



Board. During his absence James T. 
Lend rum, associate professor of engi- 
neering drawing and associate director 
of the Council, is serving as acting di- 
rector. 

The Council has a three-point pro- 
gram: Research, Information, and Edu- 
cation, 

In 1946 the Home Research Center 
was established by the Small Homes 
Council. The Center provides facilities 
at one location for intensive research in 
low-cost, family housing units. When 
completed the Research Center will oc- 
cupy a four-block area between Armory 
Avenue and Gregory Drive, west of 
First Street, in Champaign. It will pro- 
vide facilities for all phases of housing 
research and education. 

At present the Home Research Cen- 
ter contains a testing laboratory, two 
research houses, and the Small Homes 
Council Laboratory for planning re- 
search. The completed Center will in- 
clude a main building, or demonstration 
center, a production yard, and research 
and experimental houses. 

The main building will contain a 
large laboratory, shops, exhibition spaces, 
a large lecture room, and offices. The 
production yard west of the main build- 
ing will be used for the study and dem- 
onstration of construction practices. 

The research houses will be construct- 
ed and studied in cooperation with in- 
dustrial organizations. These homes will 
be designed chiefly to carry out experi- 
ments in specific problems of housing 
improvement. Site planning, land,scap-

iiiL;, and land usage can also be studied 
and demonstrated. 

File first of the two existing research 
houses was built in 1947 to study warni- 
aii heating. Built as a co-operative proj- 
11 r with the National Warm Air Heat- 
iiil: and Air Conditioning Association, 
the 3j^-room one-story house is typical 
of thousands now being built. The Asso- 
ciation has maintained a similar research 
home near the campus for 22 years. The 
new house is completely furnished and 
is occupied by a research associate. Re- 
cently the Association opened Research 
Residence No. 3 in north Champaign. 

The basement of the other research 
home is being used for several other 
heating studies, principally in connection 
with a solid fuel study. Planning and 
ilisign of homes heated by coal or coke 
Is being carried on by the University 
Department of Architecture in coopera- 
tion with Bituminous Coal Research 
Inc., the Anthracite Institute, and the 
American Coke and Coal Chemicals 
Institute. Studies include location of the 
central heating plant and the fuel bin, 
the removal of ashes, and the practical- 
ity of a sloping bottom fuel bin. Also 
being studied is the furnace in the house 
— one of the new Illinois smokeless fur- 
naces, developed by Prof. Julian R. Fel- 
lows of the College of Engineering. 

Sometimes as important as engineering 
facts are family reactions. A three-person 
family is living in this house to deter- 
mine the livability of a one-story house 
with only 768 square feet of floor space. 

In cooperation with the Lumber Deal- 
ers Research Council, the Small Homes 
Council is undertaking a research study 
directed toward giving home-owners 
economy and variety in house design 
through standardized quality construc- 
tion. Time studies previously made on 
the actual construction of 40 engineered 



houses are being used as a basis for the 
research. The project is studying and 
developing a series of standard room 
units which can be arranged easily and 
economically in a number of complete 
house plans. A series of basic plans will 
be distributed to lumber dealers through- 
out the country. 

To advance the technology of small 
house construction and to increase the 
efficiency of the contractor, the Small 
Homes Council conducted a time-study 
of construction and assembly methods 
in cooperation with the U. S. Depart- 
ment of Commerce Office of Technical 
Services. This study, conducted in 1947 
and 1948, concerned such factors as or- 
ganization of the construction job, flow 
of materials to the job, handling of ma- 
terials at the site, and construction tech- 
niques used by the contractor and his 
building mechanics. 

Six houses of the same plan and de- 
sign were built. They were constructed 
two at a time — one frame and one brick. 
When one pair was well under way, an- 
other pair was started. Lessons learned 
in the construction of one pair were 
carried over in an attempt to improve 
construction on following pairs. 

These houses, located on Hessel Bou- 
levard in Champaign, were research 
houses only during their construction 
and were turned over to the University 
for staff housing upon their completion. 

A research investigation was done on 
a house built for sale by the Structural 
Clay Products Institute on non-modular 
masonry construction. This consisted of 
a time study to obtain data on construc- 
tion time of those parts of the work 
affected by non-modular masonry. 

A study of the building of concrete 
floors for basementless houses was un- 
dertaken as a project in cooperation with 
the U. S. Department of Commerce Of-

Oiu'f upon a time a SikuiIsIi aiiin 
engineer nanieil Lieutenant Culonel 
Alejandro Goicoechea Omar, decided 
that railroad equipment must be made 
simpler and lighter. Impatient with com- 
plicated and the heavy standard equip- 
ment, he could see an economic future 
to railroads only if something radical 
was introduced to stop the trend. 

The principle that Goicoechea used 
provided a simple method of guiding 
train wheels to eliminate the weight 
needed as a precaution against derail- 
ment. This was not a new idea by any 
means. The principle has been applied 
to miniature railroads used in aniuse- 
ment parks. 

Development 

However, the main difficulty to over- 
come was to utilize the principle and 
yet to provide comfort enjoyed by pas- 
sengers on standard trains today. 




Dick Choronzy was born 
in Chicago, June 15, 1929. 
Too young to have been in 
the service, this is the far- 
thest Dick has been away 
from home. One of the 
Novy Pier ILLINI, he 
was editor of the Techno- 
graph at that school prior 
to coming to Urbana. 



Mecho 



Moioring 
Engineering research, he 
hopes to continue for 
graduate work upon grad- 
uating in 1951. Dick is a 
member of the A.S.M.E., 
and Sigma Phi Delta, one 
of the two social engi- 
neering fraternities on the 
campus. 



Goecoechea finally solved the problem 
by joining a number of short cars in 
such a manner that they would ride 
as one unit. 

After considerable study of the prin- 
ciples involved, Cjoicoechea contacted 
Mr. Jose Luis de Oriol, an outstand-

road train construction. (Photo courtesy of American Car and Foundry

ing Spanish industrialist. There was 
immediate realization on the part of 
Mr. Oriol that the new idea was in- 
tensely important and outmoded the 
older ideas on railway design. I nder 
the leadership of Oriol, Patents T til go 
S A. was incorporated. 

Several two-wheeled short units, built 
by Spanish manufacturers, were em- 
ployed in a trial run in which the motive 
power used was a diesel-powered truck 
loaned by the Spanish National Net- 
work of Railways. The test proved suc- 
cessful, albeit the short units were im- 
properly designed and the moti\e power 
was an unsuitable substitute. 

The speed attained was well over 
80 mph, and the performance around 
the curves was remarkable. It was de- 
cided to go ahead with plans and the 
services of James J. P. Mac-Veigh were 
secured to head the engineering depart- 
ment and to organize the comple.x lay- 
out of engineering problems that had 
to be carefully analyzed and assembled. 

It was realized that to introduce this 
new line of railroad equipment, the cor- 
poration would have to team up with 
manufacturers experienced in this field. 
In december, 1944, (joicoechea and 
Mac-Veigh came to New York to pre- 
sent their plans to the car builders of 
this country. The American Car and 
Foundry Company showed great inter- 
est in the matter from the very begin- 
ning. 

A contract was signed between the 
two companies on December 8, 1945, 
calling for the development of the ACF- 
Talgo, The term Talgo is derived from 
three Spanish words, tren (train), 
articulado (jointed), ligero (light), and 
the names of the inventor, Goicoechea, 
and the financier, Oriol. 

Work was started in January, 1946, 
and just recently, the ACF-Talgo was 
completed; it was the first of its kind 
e\er to be built. 

The ACF-Talgo represents entirely 
different concepts in construction of rail- 
road passenger cars. Floors are two feet, 
nine inches lower, the weight has been 
reduced 75 per cent, and the overall 
height is four feet lower than other 
streamlined equipment on railroads to- 
day. The center of gravity is two feet 
lower. Already, a Talgo has been 
shipped to Spain, and the tests have 
been succe.ssful in that countr\. 

The American experimental and dem-

oiistration Talgo consists of only a 
diesel-elcctn'c locomotive, a baggage unit 
and a coach of five units, one of them 
being for equipment and another serv- 
ing as an observation lounge. The train 
is 168 feet long at this time. Eventually, 
the length is to be tripled for general 
railroad use. 

In order to understand the principles 
of the Talgo, certain concepts in fast 
train operation must be understood. In 
most instances, speeds are restricted by 
curves. Time and time again, stream- 
liners have attained speeds of 80 inl^h, 
only to have the brakes applied for a 
curve. There is also a large centrifugal 
force to overcome, again restricting top 
speed on curves. 

In addition, the flange on present- 
day railroad wheels digs into the inside 
of the outer head of the rail, and the 
downward rub or friction of the flange 
creates a force which tends to lift the 
car and derail it. All of these difficul- 
ties have been time-consumers, with the 
result that the full use of the high- 
quality railroad tracks has not been at- 
tained. 

The radically different Talgo over- 
comes these difficulties on the basis of 
its design. It is conservatively estimated 
that 25 per cent of travel time (on most 
runs) can be saved through the use of 
this new train. 

aiiidid I r heels 
A conventional train wheel travels in 
the vertical plane of the rail. The fric- 
tion is very small when the wheels con- 
tine on a straight horizontal rail. How-

e\er, the friction becomes \ery great 
when the wheels begin to travel on a 
curve. It is quite obvious that the force 
created against the rail cannot move the 
latter, therefore, the wheel tries to leap 
the rail. 

The Talgo does away with the posi- 
tive angle of attack on the oviter rail 
as the wheels are led around the CLirve 
through the use of a three-point geom- 
etry of the underframe — like a trailer 
behind a truck-tractor. Each Talgo unit 
is supported in four places: on each of 
the two wheels at the rear of the unit 
and on two horizontal support members 
which fit into corresponding brackets 
on the rear of the unit ahead, about two 
feet above the floor. 

As each unit goes into a curve, it has 
already been turned slightly by the pre- 
ceding imit, which is already in the 
curve. The leading edge of the flange 
is pulled away from the outside rail, 
resulting in a negative angle of ap- 
proach, with the derailing factor elimi- 
nated. 

In standard railway passenger cars in 
operation today, the car is supported to 
clear the wheels under all curvature 
conditions. With the weight of the car 
centered above the point where its 
weight is transferred to the truck, a car 
will tend to lean outward on a curve 
just like an automobile. This is com- 
pensated for by super-elevation, which 
consists of making the outside rail of 
a curve higher than the inside. 

This solves the problem for high 
speeds, but when other standard equip- 



ment is used on those same rails, such as 
a slow freight train, the pressure on the 
inside rail creates a noticeable drag on 
the locomotive. 

The design of the Talgo solves this 
problem also. Instead of a truck under 
each end of the car with the axles ex- 
tending from wheel to wheel, the car is 
suspended on two stub axles, one on 
each side of the car, so that the pas- 
sengers actually walk hilirtiii the 
wheels. 

(J(ir ('.(jiistriKlinn 

There is considerably less use of ma- 
terials, especially in the undercarriage; 
and as a result, aluminum alloys have 
been used to a large extent in the con- 
struction of the Talgo. The weight of 
five units, which is practically the same 
capacity as that of a standard car, is 
less than one-fourth of the latter. Wind 
resistance is cut down because of the 
lower height of the Talgo, since there 
is a reduction in cross-section area. 

In the underframe, a "U" shaped 
center sill, of aluiuinum alloy forms the 
backbone of the unit. Cross-bearers, 
floor beams and floor stringers are "Z" 
sections while the side sill is actually 
two parallel extrusions. 

An unusual departure in railway car 
construction is the use of combination 
side posts and carlines to form the unit's 
cross-section. There is no break at the 
eaves as the hydraulically-pressed sec- 
tions form one piece from side sill to 
the center line of the room. The chan-

Research Professor of Structural Engineering, Emeritus 



Statistics show tliat approximately 
S55f of the aliiinni of the College of 
Eiigiiu-erinu; of the University of Illinois 
arc engaged in some line of engineering 
work. What does this mean? 

Does it mean that most of our engi- 
neering studetits selected engineering he- 
cause they were endowed by nature to 
he engineers? Or does it mean that our 
alumni have persisted in engineering 
work, in spite of inclinations and native 
ahility along other lines, simply because 
they took an engineering course? 

Next to selecting good morals, select- 
ing a proper occupation is the greatest 
decision in a young man's life. Some 
men look upon daylight as a time in 



which to earn money in order to enjoy 
competency in old age. Both are wrong. 
Daylight is a work time and \outh is 
a time to accumulate; but for life to be 
satisfactory the work itself must be a 
pleasure. Eight hours of drudgery paid 
for two hours of pleasure is a bad bar- 
gain. 

For e\ery man there is some employ- 
ment in which the labor itself is a pleas- 
m'e. Every man owes it to himself to 
find that occupation as early in life as 
possible. This is an obligation that many 
a man overlooks. He does not realize 
that his selection of an occupation may 
determine whether he is to have 40 years 
nf pleasant industry leading to abund- 




ance and success. Yet the choosing ot a 
right or wrong occupation may mean 
ju^t this. 

To Be or Not to Hi 

A college course is sclectetl at a time 
when a man is not in a position to make 
an intelligent choice. Statistics show that 
a very small proportion of our students 
follow the occupation of their fathers. 

Engineering students come from 
farms; students in agriculture come 
from cities; sons of doctors study to be

This article first appeared in the 
November, 1920 Technograph

does not have a first-hand everyday ac- 
quaintanceship with his prospective pro- 
fession at the time he selects his college 
course. He does not know the kind of 
ability required ; he does not know the 
environment in which the work will be 
done ; he knows nothing of the tedious 
hours of routine ; nor does he know the 
remuneration which the average man in 
the profession receives. 

The city boy, lured by the high prices 
of produce, the independent simple life, 
and the open air, decides to be a farmer. 
Likewise the country boy, lured by high 
salaries, good clothes, absence of manual 
labor, and the opportunity for social 
pleasure, goes to the city. 

If a boy is handy at fixing door bells, 
his parents and neighbors speak of him 
as a promising electrical engineer, not 
realizing the difference between an elec- 
trician and an engineer. Likewise a boy 
who plays with toy engines, and what 
boy does not, is destined to be a me- 
chanical engineer. That is, the selections 
are based upon incidents and not upon 
fundamental principles.

ULTRASONICS FOR NERVES 



By Luthvr I'eterson, U.K. '.11 



Jl'ilh the aihmncc of a nnv scifiuc. Ultrasonics, many nnv problems hereto- 
fore never diseussed or thouejht of have arisen. One of these prohlents, is the effect 
that ultrasonics has upon nerve tissue. This article hrini/s out the hii/hliyhts of the 
problem . nhich is mainly the development of neic equipment for testing these effects. 



Probably one of the newest fields of 
research in ultrasonics today is its effect 
on nerves. Many people have heard or 
seen pictures of objects being supported 
in mid-air only by this imseen and un- 
heard high frequency sound, yet \er\- 
few people have heard anything about 
it effects on nerve tissue. 

Within the last year, Professor W. j. 
Fry of the Electrical Engineering De- 
partment has undertaken the study of 
ultrasonic irradition of nerves. It is still 
too early to draw any conclusions be- 
cause of the broad scope of the program. 

Because research in this field of ultra- 
sonics is in its early stages of develop- 
ment, new equipment has to be de- 
veloped as the problem advances. As a 
result, the research problem has been 
primarih' that of instrumentation.

Pete, a junior in Elcctrj-

He was born on Jon 6, 
1927, in Molinc, lit, but 
has spent the greater part

After leaving the Army 
he was undecided about

equipment to measure the sound in- 
tensity. 

The sound tank, which uses water as 
the transmitting medium, encloses the 
sound field. The tank, which is also 
insulated to prevent reflections of the 
sound, contains the coordinate systems 
for locating and supporting the nerve 
holder and probe, the ultrasonic pro- 
jector and the focusing mirror anil 
control. 

A piezoelectric crystal, contained in 
a housing to protect it from the water, 
comprises the sound projector. The 



sound is projected through a thin dia- 
phgram which separates the crystal from 
the water ; and since only the resonant 
frequency of the crystal produces the 
desired intensity, a different projector 
Is used for each frequency. 

The principle frequency range is from 
700 kc to 1,000 /■(■ with the crystal 
producing about 175 watts of power. 
To focus this sound a six-inch focal 
length aluminum parabolic mirror is 
used ; it can be adjusted by two inde- 
pendent angular movements. In this re- 
spect it is seen that the sound is con- 
trolled somewhat like light. 

Another and very important part of 
the tank is the coordinate system which 
supports the nerve holder; it also pro- 
vides three rectangidar motions and one 
rotational movement for moving the 
probe to obtain field distribution pat- 
terns. The probe itself consists of a 
small piezoelectric crystal and is con- 
structed in such a way to make it very 
directional. 

The ne.\t and probably the most im- 
portant piece of apparatus is the nerve 
holder. Several holders have been used 
and all contain imbedded electrical stim- 
ulating and receiving electrodes. These 
holders are enclosed in a rigid envelope 
which also contains Ringer's solution 
surrounding the nerve. The electrical 
leads are brought out of the tank and

Celestial phenomena have fascinatei! 
men since the beginning of time. Sun- 
spots, though one of the smaller features 
of our imiverse, have attracted their 
share of attention. In 1610 (laiileo 
vieweii the sunspots through his home- 
made telescope. He was probably the 
first man to give them much notice for 
even the largest sunspots are barely per- 
ceptible to the naked eye. 

Heinrich Schwabc, a (jerman apothe- 
cary, started in 1826 to make dail\- rec- 
ords of the number of spots visible on 
the sun. After 25 \ears of this routine 
his labors were recognized. He found 
that the number of spots fluctuated in 
about a lO-year cycle. 

This information might have passed 
as inconsequential if it had not been for 
simultaneous records being made in otii- 
er countries on the magnetic needle 
changes, the number of magnetic storms, 
and the frequency of the Aurora Bore- 
aiis displays. 

Comparison of these records revealed 
a startling fact ; the magnitude of these 
recorded conditions fluctuated in almost 
perfect uiuson. This intriguing fact led 
observatories to keep a daily photograpli- 
ical record of the spottedness of the sun 
from 1858 to the present day. 

This lengthy and scientific record re- 
vealed more important information. It 
showed that the sunspot cycle varied 
from 8 to 1 7 years in length ; large 
spots usually lie in pairs with the mem- 
bers of the pair east and west of each 
other; the hydrogen vortices that sur- 
round the sunspots rotate in opposite 
directions in each pair as corresponding 
spots in each hemisphere rotate opposite- 
ly; and corresponding spots in each sep- 
arate cycle rotate oppositely; and sun- 
spots have strong magnetic fields. This 
information served as a basis for the 
theories that were advanced in an effort 
to explain the sunspot phenomenon. 

A Norwegian meteorologist, Professor 
Hjerkes, put forth a theory in 1926 that 
tried to explain most of the main aspects 
of the sunspot cycle. He reasoned that 
all the spots in one hemisphere during 
a given cycle are part of a single tub- 
ular vortex which passes around the sun

parallel to the sun's equator and just 
below the visible surface. The gases in 
this tube all rotate in one direction 
round and round its walls. Disturbances 
in the sun cause this tube to bend up- 
ward and break out into the open and 
form two oppositely rotating vortices. 

This assumption agrees with the 
known fact that all westerly spots ro- 
tate in the same direction in one hemi- 
sphere and all easterly spots rotate in 
the opposite direction. As this upper 
tubular \ortex travels toward the equa- 
tor an inner or lower vortex is traveling 
from the equator toward the pole. This 
inner vortex is rotating in the opposite 
direction from the outer one so when 
it breaks out at higher latitudes the spots 
it produces have their rotation directions 
reversed from the direction of rotation 
of the first mentioned sunspots. The

first \ortex sinks at the equator and fol- 
lows the path of the second vortex to- 
ward the pole and the process keeps re- 
peating itself. 

This theory agrees with facts but 
doesn't attempt to explain why the sun- 
spots in the two hemispheres behave op- 
positely. 

After several unsuccessful attempts to 
accurately predict siuispot activity, J. 
Halm advanced the hypothesis that each 
sunspot cycle was a fresh burst of ac- 
tivity and not related to any cycle of 
the past. Stewart added that sunspot 
cycles differed in magnitude but not in 
shape. 

Sir John Herschel, an English astron- 
omer, reasoned that the spots were the 
dark, solid body of the sun itself laid 
open to view. It was later proved that 
the sun has no dark, solid body so Her- 
schel's idea was discarded. 

Others likened the spots to cyclones 
and said that the bright flares that burst 
over the spots were electrical discharges 
between the magnetic fields of the spots. 
Professor Hale of Mount Wilson Ob- 
servatory said that the spots appeared 
dark because of their relative coolness 
and this coolness was caused by the rapid 
expansion of gases spirally rising from 
the core of the spots. 

The theories advanced, though some 
of them were highly reasonable, haven't 
been accepted as the final word by as- 
tronomers. Astronomers are scientists 
and scientists have an inborn passion for 
facts, thus they haven't paused in their 
search for more and more information 
about sunspots. Thanks to this ceaseless 
stud\' we now have a vast, though not 
complete, story of absolute facts about 
this well known malady of the sun. 

Present knowledge of the sunspots is 
as follows : A spot consists of a dark 
inner portion known as an umbra and 
a lighter surrounding area known as a 
penumbra. A penumbra may enclose sev- 
eral umbrae. A light ring may some- 
times surround a large spot. 

Sunspots range in size from 500 to 
50,000 miles across. Sometimes they 
form in groups that blacken out several

havior of sun spots on either side 
of the sun's equator. 



billion square miles. These large spots 
nia\ last two or three months while the 
small ones only exist a few days. 

The spots appear dark because they 
arc 1,000 to 1,500 degrees cooler than 
the surrounding gases. (This tempera- 
ture difference was definitely proved by 
two main discoveries brought about by 
spectrum studies. The sunspot spectrum 



revealed lines due to titanium oxide 
which couldn't possibh' exist in the in- 
tense heat of the surrounding surface 
of the sun. The sunspot spectrum closely 
resembles the spectrum of an electric 
arc while the sun's spectrum resembles 
that of an electric spark and it is a dem- 
onstrational fact that an electric spark is 
much hotter than an electric arc.) The 
magnetic field of sunspots has been 
measured as being 8,000 times the 
strength of the earth's magnetic field. 

A sunspot cycle starts with the break- 
ing out of small spots at points about 
43 degrees from the poles of the sun. 
They migrate toward the equator and 
become the largest and most numerous 
when they reach points about 10 degrees 
north and 10 degrees south latitude. 
This is known as sunspot maximum. As 
they move still closer to the equator they 
slowdy die out and a new cycle starts 
at the 45 degree latitudes. Spots very 
rarely occur nearer the equator than 
five degrees but one pair was observed 
that actually straddled the equator. 

These atmospheric disturbances on the 
sun are undoubtedly caused by actions 
in the core of the siui, a place impossible 
to observe. This may make it impossible 
to ever fully explain the cause and na- 
ture of sunspots, but the limits of ob- 
tainable knowledge are boundless; there 
is still a chance of cracking the sunspots' 
closely kept secrets. 

We, on this satellite, are most inter- 
ested in how sunspots affect oiu" environ- 
ment. This knowledge is even more lim- 
ited than that of the spots themselves 
because it is difficult to determine ex- 
actly what is caused by the spots and 







(T , 







what is caused by other celestial dis- 
turbances. 

Some biologists believe that sunspot 
activity has a direct influence on growth. 
They back this assumption by pointing 
out the relati\e size of tree rings as 
var\ing directly as the c\cles of the sun- 
spots.

tronic age as being their most important 
effect. Bright flares often flash out over 
spots and as they do short wave radio 
transmission is blacked out. 

As electrical discharges are emitted 
from the sunspots and bombard our up- 
per atmosphei'e, the well known Aurora 
Borealis displays are produced. These 
beautiful displays are an awe-inspiring 
tribute to the power of the mysterious 
sunspots that are 93,000,000 miles away.

World's Lightest Solid 

A solid that will float on a gas, 
Freon 1 13, has been de\eloped by West- 
inghouse. It is a foamed phenolic resin 
that weighs only 0.6 pounds per cubic 
foot. 

The chief developer of this amazing 
substance, Robert Sterling, prepares it 
by mixing a dark liquid resin. The resin 
is then baked for a few minutes at 180° 
(I, and the result is a hundredfold in- 
crease in volume. 

This foamed resin, which is only one- 
fifteenth the weight of fluffy meringue, 
promises to have widespread applica- 
tions. The most promising of these ap- 
plications seems to be in the insulating 
field. Its extreme porosity and low den- 
sity make it a natural for this field. 
Also it can be shipped as a liquid and 
expanded on site, thus saving tremen- 
dously on shipping space. It is also very 
resistant to moisture absorption. 

Its other applications seem to be lim- 
ited only by the imagination.

DEAN F. W. TREZISE 

By Clarence Niebow, M.E. '51 

As we pass the ottices ot the Colli-jii' 
of EiiginceriiiK Sciences liere at the Pier, 
we cannot help noticinji a new person- 
ality. He is Prof. Fredrick W. Trezise, 
associate dean of P:ngineering Sciences. 

Professor Trezise came to the Pier 
last lune from Galesburg, after its clos- 
ing. "He succeeded Prof. R. P. Hoel- 
scher, who had returned to Urbana to 
head the (General Engineering Drawing 
Department. 

Professor Trezise's career in engineer- 
ing has taken him to many parts of the 
globe, from as far south as Mexico to 
die northern parts of Canada. His ca- 
reer as an engineer began at Michigan 
State University, where he received his 
B.S. degree in civil engineering. He 
completed his graduate work at the L'ni- 
versity of Wisconsin where he majored 
in hydraulics; and after World War I 
he attended the University of Bonne, 
Germany. W^hile attending these insti- 
tutions, Mr. Trezise developed an in- 
terest in education, which brought him 
to Lawrence College where he served on 
the faculty for LS years. While serving 
on the faculty, he was called from time 
to time to supervise the construction of 
a number of building projects. 

W'hile at Lawrence College, AL". 
Trezise made exhausted investigations

of the mineral claims in the Sierra 
ALadre Mountains, the Black Hills, and 
the Great Bear Lake region. 

The engineering project in which Wx. 
Trezise is most commonly associated 
with is the TVA. In 1936 he was called 
upon to set up plans for the construc- 
tion of various dams in the Tennessee 
River basin. When the war broke out, 
the TVA was called upon to produce 
more power in order to supply our war 
machine. Professor Trezise was then of- 
fered the position of personnel officer 
for all management services at Knox- 
ville, Tennessee. In order to meet these 
new demands more labor was needed. 
Because of the emergency the employ- 
ment rose to 42,000 and the agency was 
geared to "run around the clock." 

While working with the TVA, Pro- 
fessor Trezise assisted in the purchase 
of the "Kingston Demolition Range," 
which later was to be known as the 
"Atomic City," Oak Ridge, Tennessee. 




DEAN F. \V. TREZISE 



Before the .'\rmy took o\er this tract 
of land, it contained the most delapi- 
dated farms in the South. It was then 
developed into the fourth largest city 
in Tennessee. This task required tre- 
mendous power that only the TVA 
could furnish. 

As personnel officer Mr. Trezise was 
able to discover certain qualities that a 
good engineer must possess in order to 
make a success in his field. 

Here at the Pier he expects to create || 
a compulsory orientation course for en- | 
gineers. This orientation course will help 
tiie engineering student get better ac- 
quainted with his chosen field and will 
give him a better perspective on the fu- 
ture. 

Engineering Societies

A.S.C.E. 

This society holds its regular monthly 
meeting on Tuesdays at 3 :00 p. m. 

The society's annual smoker was held 
on October 21. A large number of mem- 
bers were present and all had a good 
time. The boys talked camp, basketball, 
and everything but "school." 

The annual scholarship is being of- 
fered this year; also the Sponsor's prize 
will be given to the man with the high- 
est grade. These prizes will be awarded 
next June. 

A.I.E.E. 

On October 20 the student chapter 
of the American Institute of Electrical 
Engineers held an election of officers 
for the 1949 fall semester. The results 
are as follows : 

Chairman Joe Knauff 

Vice chairman Dale Hileman 

Eng. Council Rep. Richard Klensch 

Secretary Marshall Uhl 

Treasurer Robert Andrews 

Dale Hileman presided over the meet- 
ing and election. Program, publicity, and 
membership committees were discussed 
and appointed. 

Among the semester plans ^ of the 
AIEE is a trip to one of Chicago': 
television stations where the electrical 
engineers will have an opportunity to 
inspect its technical side. They will also 
have a chance to talk with T-V engi- 
neers and producers. 

Plans are also being made to bring 
Bell Telephone's technical exhibit and 
demonstrations to the Pier. This will 
be of interest, no doubt, to all engineer 
ing students.

PROF. A. W. ALLEN 

Contrary to popular belief, freshman 
lectures do have a purpose. 

Professor Allen became interested in 
ceramics by the influence of a first year 
lecture he attended while working for 
his B.S. at the Missouri School of Mines 
and Metallurgy. From there he went 
to Virginia PoKtechnic Institute to re- 
ceive his M.S. in r»4:. 




PROF. A. W. ALLEN 

From 1942 to 1943 he worked as a 
research engineer at the Harbison- 
Walker Refractories Company in Pitts- 
burgh. As a result of his continued 
interest in this field of ceramics he was 
well qualified for the position of editor 
lit the Rcfrtutfjr'us Division of (Jirti/iiir 
.lhstra,ts. 1948-49. 

In I'U.i he enlisted in the aviation 
iMili'ts and was commissioned as a navi- 
L:;itiir. He then taught navigation until 
rr;msferred to Chanute Field where he 
lircame a rated meteorologist. 

After he was discharged in 1945 Mr. 
Allen came to the University of Illinois 
tn work on the Air Force project con- 
re rning the use of ceramic products for 
C(i;!ting the internal combustion cham- 
ber of jet engines. While working on 
this project he accepted a position on 
the teaching staff here and in 1946 he 
^raited teaching. He received his assist- 
ant professorship the same year. He is 
niiw an associate professor in the Ce- 
ramic Engineering Department, and is 
nnw teaching an introductory course, 
l'\iiimetry. Microscopy, and Refrac- 
tnru-s. 

Along with his teaching, Professoi' 
Allen is very active in faculty and stu- 
ilrnt organizations. He is a member ot 
rile Engineering College policy and de- 
\(l(ipment committee and also the time 
table committee. 

Professor Allen is a member of

C-8 on Refractory Materials. 

KEITH GOODWIN 

So often it is said that an engineer 
must learn to work with people as well 
as with things to be truly successful. If 
this bit of advice is true, Keith Goodwin 
shouldn't have any trouble. He has been 
working with over 1,000 students as 
chairman of the Block I stunts at foot- 
ball games. 

Keith will graduate next June as an 
electrical engineer with power option. 
He hopes to get a job then with a pub- 
lic utility company in the field of appli- 
cations. His interest in electricity began 
in his grade school days and has in- 
creased with knowledge. 

He is a member of AIEE-IRE and 
was chairman of the student branch 
last year. In 1948 Keith was on the 
Engineering Council and was co-chair- 
man of St. Pat's Ball. Block I has 
had his services for three years. He is 
a member of Phi Eta Sigma, Eta Kappa 
Nu, Tau Beta Pi, and has been award- 
ed a scholarship key. 

Keith spent 1,^ months in the Navy 
as a printer. Photography is his main 




hobby. He was raised in Springfield, 
Illinois, and has a brother who is an 
electrical engineer working for (jood- 
rich Rubber Company. 

The first big step of his career will 
be made next year — he's getting married. 



PROF. NEWLIN D. MORGAN 

A successful ci\il engineer signed the 
name of Newlin D. Morgan to a Uni- 
versity of Illinois teaching contract by 
lamplight some 26 years ago in the 
mountains of Colorado. It was in Sep- 
tember of 1924 that he started here as 
an associate. 

His record prior to that time showed 
the development of his interests and

abilities. He was \aledictorian of the 
North Denver High School class of '06 
and attended the University of Colorado 
on scholarships. It was there that he re- 
ceived his B.S. degree in 1910. 

Professor Morgan's first job after 
graduation was with the American 
Bridge Company in Chicago. He helped 
them organize their branch office in 
(lary in 1912. It was while working 
with this company that he became inter- 
ested in designing. 

This interest was developed during 

the next few years while working for 

the Chicago, Milwaukee and St. Paul 

Railroad designing their buildings. This

A.I.E.E.-I.R.E. and A.S.M.E. 

A display of cooperation ami coordi- 
nation that has possibilities for bringing 
some outstanding programs to student 
engineers was evidenced recently by the 
American Societ\- of Mechanical Engi- 
neers and the Institute of Radio Engi- 
neers — American Institute of Electrical 
Engineers. These organizations spon- 
sored a joint meeting October 28. 

Bernard G. Hatch of the General 
Electric Company spoke on the latest 
de\ei()pnients of gas turbines. He ex- 
plained the turbines and their applica- 
tions in relation to power plants and 
locomotives. Interesting films, related to 
the subject, were also shown. 

This method of organizations com- 
bining to present programs of general 
interest gives the "wheels" excellent ex- 
perience in working with other groups. 

A.S.M.E. 

AS ME officers elected this semester 
include Al Helene, James Eberhardt, 
and Wolfgang Junkel. Their respective 
positions are secretary, assistant treas- 
urer, and junior representative to the 
Engineering Council. 

A rousing discussion concerning the 
methods of electing officers was termi- 
nated by a motion that the 
executive committee study 
the question with the pur- 

MTOPyn pose of proposing amend- 

iMj]^) ments to the constitution. 

November 2, Dean H. 
H. Jordan spoke on "Placement Pro- 
cedures and Prospects." The dean out- 
lined the placement structure employed 
by the University which emphasizes 
decentralization. The University Place- 
ment Service is broken down into func- 
tions of the college offices, which in 
turn are divided into departmental func- 
tions. In the case of the Mechanical 
Engineering Department, placement 
services are handled through the office 
of the Dean by Professor Ryan. He 
contacts the students and handles per- 
sonalized services for the prospective em- 
ployers. 

Of the personal services offered, the 
character rating sheet is of prime impor- 
tance to the student. The Mechanical 
Engineering Department has made up a 
character sheet on which are evaluated 
such qualities as personality, industry, 
and ability to get along with people. 



18 



These are evaluated by each student's 
instrLictors. The results of several rat- 
ings are compiled and distributed to in- 
terviewers to aid them in making em- 
ployment decisions. 

Another fact that Dean Jordan em- 
phasized was the importance of keeping 
in contact with the school after gradua- 
tion. As an illustration, he stated that 
he could recommend jobs that pay from 
#280 to $800 per month to the quali- 
fied engineers, if he only knew of those 
in need. 

Following the talks by Dean Jordan 
and Professor Ryan, a discussion period 
was held to clear up questions which 
had not been answered. Dean Pierce 
was also present and helped to answer 
questions. 

A.F.S. 

Charles Drury chose a very interest- 
ing and pertinent subject to bring before 
the foundrymen's club at their Novem- 
ber meeting held in the M. E. building. 
He spoke on the differences between 
classroom instruction and foundry work 
as it is performed in industry. He also 
pointed out the difficulties one encount- 
ers in making the change from school to 
work. 

A recent graduate of the University, 
Chuck is now employed by General 
Motors in Danville and his experiences 
in making the change from student to 
worker are still fresh in his mind. 

Membership in the AFS is open to 
all students interested in foimdry work. 
It is a branch of the national Ameiican 
Foundry Society. 

PI TAU SIGMA 
Pi Tau Sigma, the national M. E. 
honorary, held its fall pledging smoker 
on November 8 in the facultv lounge 
of the mini Union. Prof. D. S. Clark 
of Purdue, who is national secretary, 
was scheduled to give a talk, 
but as he was unable to at- 
tend, Henry Funckes of the 
local chapter gave liis talk 
in his stead. 

Some remarks were made 
by Prof. Norman Parker, 
head of the Mechanical En- 
gineering Department; and the history 
of Pi Tau Sigma was related for the 
benefit of the new initiates by Boubene 
Jaremis, president of this chapter. 




Refreshments were then ser\eil to tin- 
assembly. 

MU SAN 

!VIu San, municipal and sanitary engi- 
neering honorary fraternity, held its sec- 
ond meeting of the current semester on 
October 26. 

The primary purpose of the meeting 
was the social mingling of old and new 
prospective members. The program con- 
sisted of slide pictures and a lecture 
given by one of the members, Ray Plum- 
mer, on water supply methods for the 
island of St. Croix in the West Indies. 

The date for the formal initiation 
was set for November 9. Plans were 
also made for a field inspection trip to 
the sanitary and water supply districts 
of Springfield on December 3. 

M.I.S. 

The MIS was indeed fortunate to se- 
cure Dr. Maurice D. Cooper to speak 
at their meeting November 9. Mr. 
Cooper was really well qualified to talk 
on "The Coal Industry and the (Gradu- 
ate Mining Engineer." 

Besides having 25 years of experience 
in mining, he is chairman of the AIME 
committee on student relations. More- 
over, Dr. Cooper is director of voca- 
tional training for the National Coal 
Association. 

The short business session at this 
meeting included an outline and a dis- 
cussion of the Career Conference, De- 
cember 5, 6, 7, and 8. 



E. E. Senior Inspection Trip 

The senior inspection trip which was 
dropped during the war was again re- 
vived through the efforts of the AIEE- 
IRE. The interest shown in the trip 
this year will undoubtedly warrant a 
required trip in years to come. It seems 
to be a well proven fact that the knowl- 
edge gained on such a trip easily out- 
weighs expenses and mconvenience in- 
volved. 

Three days, November 9, 10, and 11, 
were taken for the trip this year. Ap- 
proximately 200 students from the elec- 
tronic and power options went on the 
trip. This number was split up into fi\e 
groups in order to facilitate guide serv- 
ice through the plants. Individual itin- 
eraries were set up for each bus so as

We received word that Tau Beta Pi 
has again been in the throes of allowing 
women to become fidl-fledged members 
of the organization. 

According to the present constitution, 
women are not given full membership, 
but outstanding women in the field of 
engineering may be awarded the Wom- 
an's Badge. This is purely honorary and 
does not award full membership. In the 
past 25 years, 96 women have been so 
honored. Of these, 95 have been award- 
ed for honors in undergraduate work 
and one woman has been honored for her 
attainments in the field of electrical 
engineering. 

At latest reports the men have not 
relented but the women are still trying 
to break into the ranks of the elite engi- 
neering honorary.

University Fire Fiyhters 
There is one biulding on our engi- 
neering campus that appears quite inde- 
pendent. It is the fire department 
building, located directly behind Civil 
Engineering Hall. Although this build- 
ing shows very little activity, compared 
to the hustling crowd that pours in and 
out of other buildings, it plays a re- 
sponsible role in the maintenance of 
such a large University as our own. 

Considering its relative responsibili- 
ties, the University of Illinois fire de- 
partment is one of the best equipped 
and most efficient fire departments in 
the state. 

Heading the fire department person- 
nel is the fire chief, F. S. Stateler, who 

DECEMBER, 1949 



is in ciiarge of the fire prevention pro- 
gram. His duties require him to inspect 
all buildings on the campus to determine 
the number of people they may safely 
accommodate. 

He also determines any violations of 
the building code. These violations may 
include such items as improper construc- 
tion, improperly placed fire doors, and 
inadequate exit or stairway space. 

The remainder of the personnel is 
divided into two platoons, each consist- 
ing of 11 men and working on a 24- 
hour shift. The captain and first lieu- 
tenant are in charge of one platoon, 
while the assistant chief and second lieu- 
tenant are in charge of the second pla- 
toon. The nine remaining men of each 
platoon are divided into two companies. 
The engine company handles all first 
floor alarms, while the ladder company 
handles alarms of two stories or greater. 

Everyone in the fire department must 
drill once a week to be constantly fa- 
miliar with their equipment and its use. 
They must also have a knowledge of 
fire fighting procedures. 



Their academic training covers nine 
different subjects. They are: (1) minor 
fire extinguisher practice and use; (2) 
ladders; (3) hoses; (4) salvage and 
overhaul; (5) water pressure and fire 
stream; (6) fire apparatus (rolling 
stock only); (7) ventilation; (8) res- 
cue work; and (9) inspection. 

The equipment of the University fire 
department is rated very highly. Its big- 
gest fire truck is known as a "Quin" 
among firemen because it carries five 
types of equipment which include a 65- 
foot aerial ladder, a booster tank, hose, 
a pump capable of delivering 1,200 gal- 
lons per minute, and a rigid ladder as- 
semblage consisting of seven ladders 
ranging from 16 to 45 feet. Another 
truck on hand is known as a "Quad ;" 
it carries a 750 gpm pump, a booster 
tank, hose, and a rigid ladder. The re- 
maining equipment includes a hose wag- 
on, an emergency pick-up truck, life 
nets, life lines, a deluge pump and a 
high-pressure pump.

Peanuts for Students . . . 



Thi-re are approximately 19,500 students, 
3,054 taeult)', and 2,592 nonacademic per- 
sonnel at the University of Illinois. Each 
group has its various organizations. And each 
group pulls strings, plays politics, and in gen- 
eral proceeds independently and without con- 
sideration of the others. 

An example is the virtual monopoly en- 
joyed (and I do mean enjoyed) by the Civil 
Service Employees Council, the official organ- 
ization of non-academic personnel on campus. 
They receive the profits from 39 candy, Coca 
Cola, and peanut dispensers placed in campus 
buildings. But these profits aren't peanuts! 
Between January 1 and November 15, 1949, 
the net profit from these machines was about 
$2,000. That's not bad — but it isn't right! 
What does the CSEC do with the profits? 
Besides maintaining a running balance of 
about $2,300, they throw a jamboree and a 
picnic each year. 

Aleanwhile, many student organizations 
must perform their educational and Univer- 
sity-promoting functions without adequate 
finances. Practically all student organizations, 
and particularly our engineering societies, are 
supported only by dues from the members. 

Last spring the Commerce Council, badly 
in need of operating funds, petitioned for in- 
stallation and control of vending machines in 
David Kinley Hall. Their petition was ap- 
proved by the Committee on Student Affairs 
and was referred to President Stoddard for 
authorization. 

Despite approval by CSA, its chairman. 
Prof. Harry J. Fuller, and Dean Fretl H. 
Turner then sent Stoddard a letter asking 
for a decision and suggesting that student 
groups not be authorized to control canteens. 
The reason? The CSEC has no other method 
to finance their welfare program; students 
may promote dances and other activities to 
raise money. 

However, instead of buying flowers for 
the sick and the dead (as Dean Tinner 
has said) profits have been used almost ex- 
clusively for entertainment. In fact the State- 



ment of Belief and Intention, the policy of 
which the CSEC obtained authorization, has 
at the top of a list of example expenditures, 
"group, departmental or campus-wide parties, 
picnics, or other social events." Apparently 
Dean Turner didn't know this. 

Objection to the other point? One needs 
only to ask Dean Hampton about the profits 
of recent student dances. ^laybe Turner 
doesn't know this either! 

Maybe Turner would prefer to be dean 
for nonacademic personnel rather than dean 
for students! 

Yet there is a definite need for some kind 
of unifying acti\ity for the nonacademic per- 
sonnel. 

Last May the Technografih sent a letter 
to Stoddard asking that the position of 19,000 
students be considered along with that of 
Dean Turner and Professor Fuller. At the 
time of this writing, Stoddard has not made 
a decision. However, the provost, Coleman R. 
Griffith, has proposed a plan involving a joint 
student-faculty-nonacademic board to appor- 
tion profits from vending machines. 

The lUinois Technograph approves this 
proposal if the proposed board will have pro- 
portional representation and if profits are dis- 
tributed fairly. 

Those organizations doing the most un- 
selfish and constructive work should be the 
recipients of the students' share. Most needy 
and most worthy are the college councils that 
made possible the First Annual Career Con- 
ference. Improvement of the L^niversity is 
their main emphasis; student benefit is sec- 
ondary. 

Were it not for action by members of the 
Engineering Council, last spring's Engineering 
Convocation and Effective Instructor award, 
the Dad's Day tours, the Career Conference, 
and the forthcoming engineering open house, 
I SEE, would not be realities. And these are 
all definite services to the L^niversity. 

We students mav be paving for peanuts, 
AND THAT'S ALL WE'RE GETTING!

Do YOU REMEMBER when winter meant storing the family 
car till spring;? Not so many years ago, a car owner's fear 
of an ice-shattered motor was a dread reality ... if he didnt 
drain his radiator and store his car once cold weather hit! 

What was needed— acutely— was an automobile anti-freeze 
that would prove always dependable yet economical. One 
that would hold up under any operating temperature. That 
wouldn't foam and boil away. That would resist rust and 
corrosion to the nth degree. 

That's where Union Carbide research entered the picture. 
The result? "Preslone" anti-freeze. Since then this product 
—the first all-winter anti-freeze— has assured millions upon 
millions of motorists of ever-improved driving performance. 



with assured safety . . . throughout the bitterest weather. 

This is but one example of the way the people of Union 
Carbide are helping to better our daily living. And UCC

^^Magnet Wire? 
I didn-t even know ROEBLING made it I... 





THIS VISIT to just one of the 
Rocbling works has been an eye- 
opener. Everyone in my line knows 
Roebling wire rope, but I never 
heard that you stack up so big in 
electrical wires and cables." 



i^ 



-k 



Many people are surprised to learn of the 
wide diversity of Roeblinn;'s line of wires 
and wire products. It is often news, too, 
tiiat several different items in tlie Rocbling 
line are used in one and the same field. In 
mines and quarries, for example, Roebling 
Wire Rope, Aggregate Screens and Port- 
able Electrical Cable are all likely to be on 
the job together. Wherever there's industry, 
there are Roebling products that help bring 
highest efficiency and lowest service cost. 



WOVEX WIRE FADKIC. Rocbling 
weaves wire screens to meet every sort of 
industrial requirement. From large size 
Aggregate Screens to closely woven Filter 
Clotlis, wires made of special steels and 
non-ferrous metals bring new measvires of 
resistance to abrasion and corrosion. 

WIRE nOI'E. Roebling wire rope is 
made in a complete range of t)pes and 
alwa\s affords a rope that's riglit for every 
application. For easy handhng, smooth 
operation and long life on the job, Roebling 
Preformed "Blue Center" Wire Rope is 
unsurpassed. 

EI.E«'TltirAI. WIKE - < ABLE - 
»1.\«>'ET W'lltE. With more than 60 
standard tvpes, Rocbling's line of electrical 
wire and cable meets practically all trans- 
mission, distribution and service needs . . . 
The insulation of Roevar Magnet Wire is 



10 to 40 times tougher than other t\'pes — 
first choice for high-speed winding. 

■tOI'>'U— FLAT— SHAPE ■> WlltE. 

Manufacturers adopt Roebling high carbon 
wire for its dependable uniformity which 
minimizes machine stoppages and rejects, 
and pulls down production costs.

Whatever career you are studying for, 
when you get on the job you will find one 
or more t\pes of Roebling products serv- 
ing there, dependablv and at low cost.

work in di-signiii}; defpi-iu'd his growiiif; 
iiitcifst in architi'ctiiri'. 

The years from 1918 to 1923 found 
Professor Morgan back in Colorado. 
This time he was working for the L'. S. 
Bureau of Public Roads. In this posi- 
tion he not only ilesigned bridges but 
had the opportiuiity to supervise the ac- 
tual construction in the field. 

In 1923 the government made him 
district engineer for the Western states. 
It was during this period that he de- 
signed and supcr\iseil the construction 
of the highest two-hinge arch bridge in 
Colorado. He received his professional 
degree from Colorado University in 
1925 on the basis of this achievement. 
His first teaching experience came in 
1923 when Professor Morgan took an 
eniergenc\' leave from his government 
work to fill a vacancy in the Colorado 
University staff. 

Illinois managed to secure his services 
the next year, and he has been here ever 
since. He has been a senior professor 
and on the graduate faculty for the past 
15 years. He received his M.S. here in 
1'I28. 

Professor Morgan is a member of the 
American Institute of Architects, the 
American Society of Engineering P"du- 
cation, the American Society of Civil 
Engineers, American Concrete Institute, 
American Association of University Pro- 
fessors, Tau Beta Pi, Sigma Xi, and 
other honorary societies. 

He was associated with Hardy Cross 
in writing Statically Indeterminate 
Structures, published in 1926, and Con- 
tinuous Frames of Reinforced Concrete. 
published in 1932. The latter book is a 
standard text in use in most of the uni- 
versities and engineering offices through- 
out the country. It has been translated 
into Spanish and is widely used in South 
America. 

While attending the University of 
Colorado, Professor Morgan was editor 
of their Engineering Journal. 

Two of his children are professors, 
one is doing graduate work here at Illi- 
nois, and the fourth is in high school. 
Five members of the family are life 
members of the Univei'sit\' Alumni asso- 
ciation. 

Professor Morgan now spends his 
summer months working on a cabin in 
the Medicine Bow National Forest of 
Wyoming with the help of his youngest 
son.

features will be incorjiorated into pro- 
duction engines as quickl)' as possible. 
The engine is protected from icing 
conditions by internally heated, hollow 
parts at the nose; this includes inlet 
guide vanes, fairings, and forward fr,-ime 
struts. 

Versus Cancer 

The atomic pile at ( )ak Ridge Na- 
tional Laboratories Is supplying a potent 
power in the fight against cancer. 

Needles of 53 per cent nickel, 45 per 
cent cobalt are made radioactive by 
exposure to the radiations of the atomic 
pile. The small, easih- fabricated needles 
can then be inserted into diseased tis- 
sues. 

It would require over a million xolts 
for an X-ray tube to produce gamma 
rays equiwilent to those of the nickel- 
cobalt wires. The gamma radiations are 
similar to those of radium but cover a 
narrower band of frequencies. The half 
life is five years. 

Both the alloy needle and the process 
of making it radioactive are low in cost. 
It is utilized in cancer therapy in the 
same manner as gold needles contain- 
ing radon gas. Moreover the radioacti\e 
needles are about half the size, and can 
be handled and located easily with elec- 
tromagnetic tongs. 

Dr. William Myers of Ohio State 
Universit)' was responsible for develop- 
ing the use of this new needle; and the 
past year of clinical testing at OSU has 
seen the achievement of important gains 
in treating cancer. 



Diesel Switcher 

Lima-Hamilton Corporation's new 
diesel switching locomotive is powered 
by the recently announced Hamilton 
9" by 12" eight-cylinder, supercharged, 
four-cycle vertical diesel engine, which 
provides a full 1,000 brake horsepower 
for traction, utilizing the full capacity 
of the traction motors. The switcher, 
weighing 120 tons, has a maximum 
speed of ()0 miles per hour. 



The 1 .IIIHI-horsepower switcher has a 
diesel engine radically different from 
those ordinarily used in switching loco- 
moti\es. Additional features include its 
operation at HMEP (Brake Mean 
Effective Pressure) of 165 psi. with 
a firing pressure of l,2n(l to l,4(ltl 
pounds. This is far he\ond the pres- 
SLire used in any other engine ot this 
gener;il type. 

Jet Power for Your Car 

Thompson Proilucts, Inc., Cleveland, 
Ohio, is now making a device that will 
provide that extra burst of power need- 
ed for motoring emergencies. It is a 
completely automatic auxiliary carbure- 
tor known as the Vitameter. 

The flange of the Vitameter is in- 
serted between an engine's manifold 
and its carburetor. When the manifold 
vacuum drops, due to the car's gas 
pedal signaling for added speed, a float 
chamber and a metering jet sprays Vi- 
tane, an alcohol-water, tetra-ethyl leail 
solution, into the throat of the main 
carburetor. 

This "shot in the arm" caiises the 
gasoline to burn more evenly thus elim- 
inating "ping" and provides an extra 
burst of speed. 

Thompson Products reports that 13 
per cent Vitane in gasoline vapor is 
enough to raise a gasoline's octane rat- 
ing 10 numbers. Enough Vitane for 150 
to 200 miles costs 35 cents and the Vita- 
meter itself costs $}i2 and up, depending 
on size. 



"Mrs. Jones ivas outspoken at our 
club meeting today/" 

"I can't believe it. Jl'ho outspoke

An American traveling in the Nether- 
lands met a Hollander who, on learning 
the traveler's nationality, said, "Our 
flag is red, white, and blue, too. When 
tax season approaches we begin to feel 
blue, and when we receive our state- 
ments we turn white, and when we |ia\- 
we are red ! " 

"Yes," replied the American, "but in 
the United States we see stars as well."

Now television is flashing visual enter- 
tainment, news, and educational material 
to millions of people daily. The "inside 
story" of its rapid growth is the history 
of some remarkable tubes. Inside these 
tubes, electrons are put to work— to per- 
form, for your benefit, the miracle of long- 
distance vision. 

The screen of your direct-view television 
receiver is actually the face of a tube — the 
kinescope developed by Dr. V. K. Zworykin 
and his colleagues of RCA Laboratories — on 
which electrons in motion "'paint" pictures. 
A tube, too, is the "eye" of RCA's Image 
Orthicon television camera, which can "see" 
clearly by the light of a match. 

And since you asked for big-picture tele- 
vision, they developed projection receivers 
—also a way to "weld" glass and metal, thus 



speeding the production of 16-inch direct- 
viewing tubes ... at lower cost. 

To these basic "firsts," RCA scientists 
have added advance after advance, which 
are daily bringing television into the lives 
of more and more people. 

How you profit 

Advanced research in television tubes is 
just one way in which RCA Laboratories 
work in your interest. Their leadership 
in science and engineering adds value

The two purlines, tliose roof members 
which are parallel to each other the 
length of the car, consist of extruded 
"j" sections. 

The unit ends of the coaches are of 
Plymetl where partitions are required: 
otherwise they are open in order to form 
a continuous coach. The two dia- 
pligragms which are a|iplied between all

units provide a smooth exterior and in- 
terior, but are principally for weather 
protection. The diaphgrams are closed 
by specially designed zippers with seal- 
ing lips which will hold through all de- 
grees of tension ; they pressin-e-proof the 
closure and form a dead air space for 
insulation. 

These combined features have cut 
down the initial costs in locomotion. It 
is to be remembered also that there is 
a resultant lower fuel consumption. 

The couplers on the Talgo are en- 
tirely different from those of conven- 
tion cars. When uncoupling a Talgo 
unit, the process is pretty much like un- 
coupling a truck trailer. Two five-inch 
dolly wheels are lowered to the track 
to keep the unit upright since there are 
only two conventional wheels on the 
iHiit. Under ordinary operation, these 
support wheels are folded into the floor 
hidden from sight. 

The entire train is powered from the 
locomotive. This includes electricity for 
the train as well as for traction. Head- 
end generators provide 208/120 volts, 
30 cycle three-phase A (J power to the 
train. A special ACF-designed light- 
weight air-conditioning system provides 
vear-round weather control with freon

refrigerant for cooling and electric 
heaters for heating. 

Tin- Locfiiiiiitii'C 
The cab structure is all-welded — 
of girder type design to keep deflection 
to a minimum. The latest metallurgical 
processes were used to reduce welding 
distortion and creep in the assembly. 

In the underframc, 12-inch LAHT 
channels are spaced 42 inches apart from 
the center sills and only one cross-bearer 
is used. The exceptionally wide spacing 
was made in order to permit the main 
propulsion engines to be suspended as 
close to the rail as possible. Welding 
was used throughout and the entire un- 
derframe structure is stress-relieved. 

The main propulsion engines consist 
of two Hercules model DNXV8S die- 
sels connected to the traction generators 
through a ventilateil bell housing. Low 
weight per horsepower is obtained in the 
diesels (approximately 13^ Ib/hp) by 
fabricating many of the frame members 
from low-alloy high tensile steel into a 
compact design. 

The exceptionalh' wide r a n g e of 
speed - tractive - effort performance (17 
ml^h to 105 inph without exceeding the 
continuous rating of the traction mo- 
tors) is the result of using two extra 
heavy-duty motors with each of the 405 
hf input generators. This means that 
the locomotive can be used with equal 
facility both in high-speed level opera- 
tion and in heavy grade mountain serv- 
ice. 

Rubber-in-shear engine mounting 
units, probably the largest ever used in 
locomotives, practically eliminate vibra- 
tions in the structure. This vibration 
elimination should increase the over-all 
life of the vehicle and reduce the main- 
tenance considerably. 

As can be seen from the foregoing de- 
scription, the name Talgo not only sig- 
nifies a train that is lighter and joint- 
unit built, but also stands for a new 



advance in the science of railroading. 
There have been many new designs in- 
troduced within the past 20 years but 
none as spectacular and revolutionarv 
as this. 

The Talgo doesn't look like a con- 
ventional train. Low-slung, it resembles 
a tubular snake as it makes the turns 
without slackening speed whatsoever. 
Doors for entry are spaced every fifth 
car (unit), with the wheels practically 
concealed. It looks exactly what it is — 
a departure from the conventional and 
a change for the better. 

The Talgo is definitely a train of to- 
morrow. And who knows — you may be 
ridinir in it tomorrow.

THE TECHNOGRAPH 




Why we know this wax carton will stand up 



Cartons and wrapping papers coated with 
paraffin wax have been used in food packag- 
ing for many years. They must be able to 
withstand rough treatment. Their ability to 
stand up depends largely on the strength and 
sealing qualities of the coating agent. Yet 
until a few months ago, there was no accu- 
rate way to measure these qualities in paraf- 
fin wax. 

Recent experimental work in Standard 
Oil's laboratories has resulted in a new elec- 
trically controlled quantitative test. Ex- 
pressed as Indiana Coating Index, this test 



gives, for the first time, an accurate yard- 
stick of wax qualities which may be corre- 
lated with performance in service. It makes 
possible the production of uniformly high 
quality coating agents. 

The Indiana Coating Index is only one of 
many scientific tests developed in Standard 
Oil laboratories. Standard pioneered in qual- 
ity-testing, as it did in developing many 
petroleum products that have contributed to 
better living. There is no ceiling on what can 
be accomplished by Standard Oil researchers, 
present and future.

EXPLORE 

New Frontiers of Industry! 

Br EDWIN H. BROWN. Vice PresUleiit. Engineering Devehpment Division 
Allis-Chalmen Manufacturing Company {Graduate Training Course I90S 



WILL IT WORK? Is it prac- 
tical? Is there a heller 
way to do it? If you feel the 
challenge in questions like these 
and get a thrill out of finding 
the answers — perhaps you're 
cut out for research. 



There are a lot of us like that 
hereat Allis-Chalmers. Pio- 
neering beyond the immediate 
frontiers of industry has been one of the 
major factors in the growth of this com- 
pany for over 100 years. Yet today we're 
finding more exciting frontiers to explore 
than ever before. 

My part in this work started back in 
1906 when I joined the Allis-Chalmers

various materials for pumps and hy- 
draulic turbines. Material under test is 
electronically vibrated at a high rate 
while submerged in water. 



G raduate Training Course, from the Uni- 
versity of Nebraska. During my two years 
in the course, I spent a good deal of time 
on the test floor. That's the spot where 
original thinking, new designs, and new 
methods pay oft in results. It's a great 
\antage-point from which to watch in- 
dustrial de\elopmcnt at work. 

After completing my GTC, I worked 
as a test engineer ... as development 
and sales engineer on steam turbines . . . 
as a chief engineer and department 
manager . . . and into my present work in 
research and development. 



Unusual Range of Activities 

Research here at A-C covers a 
tremendous range of industrial 
fields. I might point out that 
product de\elopment is con- 
sidered a responsibility of each 
product department, while the 
central research and develop- 
ment organization works with 
the many departments in a statT 
capacity. Since Allis-Chalmers produces 
important machinery for every basic in- 
dustry, you can see that our develop- 
ment work is extremely varied. 

It includes such things as methods of 
burning coal deposits underground, to 
produce power without the intermediate 
steps of mining, processing and transport- 
ing the fuel to power plants. We're de- 
veloping equipment for the application 
of atomic power in naval vessels. Work- 



ing closely with engineers of the Turbo- 
power Development Department, we're 
developing gas turbines for ship propul- 
sion and high-temperature gas turbines 
for locomotive service, burning powder- 
ed coal. 

Other engineers and scientists are en- 
gaged in pure physical research into fac- 
tors that influence power transmission 
oxer long lines. There's constant depart- 
mental research and product develop- 
ment going on in the fields of flour 
milling, ore processing, water condition- 
ing, hydraulic turbine design, electronics, 
new manufacturing methods and tech- 
niques, industrial design. 

Pick Your Spot 

Graduate engineers selected for the Allis- 
Chalmers Graduate Training Course have 
a unique opportunity to explore many 
engineering and industrial fields, and find 
the work that suits them best. Here, you 
help set your own course— may change 
it as you go along and special interests 
develop. 'Vou can gain first-hand expe- 
rience with almost any major industry

( L'ojitinufd liijiii I'ayc !_' ) 

do you want to eiul lite? Do you want 
to be rich ? Do you want to be famous ? 
Do you want to have power? Do you 
want to render ser\ice? C^r do you want 
to wander and end where you will? 

The man in Chicago who does iint 
know whether he wants to ^o to New 
York or San Francisco is not likeh to 
get to either. Likewise the man w lio 
vacillates between riches and service is 
no more likely to get the one than lie 
is to render the other. Moreo\er, the 
man without a definite goal is likely to 
be a tramp on life's highway, following 
the road of least resistance and arriving 
nowhere. The first question, therefore, 
is, "What will be your principal aim 
in life?" Do you want to be rich, fa- 
mous, or powerful ; or do you want to 
render service? 

Give or Take 

The product of life is character. 
Character forms slowly. It is plastic 
while forming, but once set, it is hard 
and resists change. The characteristics 
of a young man are many and varied, 
but in an old man some one character- 
istic predominates. Benevolence becomes 
a habit through a lifetime of practice. 
Selfishness becomes a fixed trait upon 
continually trying to get the lion's share 
of everything. A bully is defined as a 
person who continually intimidates oth- 
ers by manner or threat. 

Some methods, not all, of getting rich 
require that one disregard the rights of 
others, or even require that one take 
what morally belongs to another. Some 
methods, not all, of attaining power re- 
quire that one bluff and brow-beat his 
associates. Some occupations promise 
great riches, but only through the de- 
struction of character ; other occupations 
are incompatible with wealth yet develop 
characters of the highest type. 

The aim of life has not been fixed 
until, not only a desired acquisition, but 
also the desired character has been se- 
lected. For wealth obtained by sharp 
practice is as far from wealth and be- 
nevolence as plenty is from poverty. If 
you want riches and honesty you must 
not, in your eagerness for riches, do that 
which develops selfishness and dishon- 
esty. Likewise if you want power and 
meekness, and they are often found to- 
gether, you must not, in your eagerness 
for power, become a bully. 

Of the two aims of life, acquisition 
and character, character is the more de- 
sirable. Acquisition is from without, 
whereas character is from within. (Jhar- 
tir/er uithout m quisltirjii iiiiiy he victory, 
but acquisition nt the expense of char- 
acter is defeat. 

Having decided upon the aims to be 
attained, you are in a position to study 



the \ari()us occupations and select tlic 
one which will most easily enable \-ou 
tn attain these aims. Any productive oc- 
cupation industriously and properly 
practiced by a man having ability in 
that occupation will result in a high 
type of character aiul sufficient wealth 
to meet an\ reasonable wants. The prob- 
lem, then, is to select the occupation in 
which one has a sufficient interest to 
be industrious and the occupation for 
whicli he has the peculiar t\pe of abil- 
it\ reciLiired. The solution of this prob- 
lem requires consideration of the fol- 
lowing questions: 

1. What is the nature of the work? 
If you are planning on being a ci\il 
engineer you want to know what a civil 
engineer does. What does a civil engi- 
neer do the first year, the first five 
>ears, and the first ten years after grad- 
uation ? Hy this is meant, not the spec- 
tacular thing which he does once a year, 
but the routine of work which he does 
eight hours a day, six days a week, and 
fifty-two weeks a year. Is this the work 
you can do with interest? If so industry 
will be a pleasure. Or is it work for 
which the pay envelope will contain the 
whole compensation ? 

2. Lender what conditions will the 
work be done? Will it be indoors or 
outdors? Will it permit home life? Will 
location be permanent or will it require 
shifting from place to place? Will it be 
in the city or in the country, in settled 
or desert places? Will there be danger 
or safety? 

3. What compensation may you ex- 
pect the first year out of college? The 
first five years? The first ten years? 
What are the big prizes for the few 
highest men in the profession in money, 
in fame, in power? 

4. What will your personal relation- 
ship to other men be? Will your rela- 
tionship be mutually pleasant? Will you 
have to bulldoze others to get ahead ? 
Will you have to keep others from bull- 
dozing you to keep from getting behind ? 
Will you be called upon to inflict in- 
justice to others? Will you be called 
upon to promote business activities 
which are questionable? 

5. What are the chances for failure? 
Do all men in the profession succeed in 
making at least a living or are some 
compelled to give up and shift to other 
work to make a fair living? 

6. Is the profession looked upon witli 
honor? Does the mere fact that you are 
in the profession give you prestige? 

8. To what extent do you possess the 
required personal attributes? Do you 
have sufficient interest in the profession 
to induce you to overcome any natural 
deficiencies ? 

The first reaction in reading these 
questions is that they are extensive and 



unnecessarily formal. This is because 
they are questions which we have never 
considered — a fact which only increases 
their importance. 

Natural Selection? 

To answer the above questions intel- 
ligently requires an amount of knowl- 
edge and a power of self-analysis not 
possessed by the average freshman. That 
is to say, the average student selects a 
course in college at a time when he is 
wholly unprepared to select the line of 
endeavor in which he should spend his 
whole life. To expect an intelligent se- 
lection at this time is to expect the im- 
possible. 

To realize the truth of this statement 
it is only necessary to talk with fresh- 
men about the factors which led to the 
selection of their course. It is true that 
some freshmen have pretty definite rea- 
sons for their selection, but in many 
cases the decisions are based upon con- 
ceptions that are preposterous and which 
show a lack of knowleilge of true con- 
ditions which is lamentable. 

It is true that many students do se- 
lect courses preparing them for work 
which they like and in which they are 
successful. This is due in part to the 
fact that a boy's liking for a profession, 
illogical and unanalyzed as it may be, 
develops an industry and application 
which will make him proficient even 
though his greatest native ability may 
be along some other line. Proficiency, 
in turn, breeds interest and enjoyment 
which overcome some slight misfortune 
in the original selection. Good training 
may also overcome considerable lack of 
native ability. 

Although the adaptability of youth 
partly overcomes the misfortune of a 
wrong selection, this fact should not be 
permitted to interfere with a later, and 
more intelligent selection, if the first is 
found to be ill-advised. To persist in 
trying to be a lawyer because one has 
a law degree is to persist in going to 
the wrong city because one has turned 
onto the wrong road. 

It's Not Too Late to Think! 

To senior engineering students the se- 
lection of a permanent occupation is a 
serious matter. Many of you were 
brought up on a farm, but thought you 
would like to be an engineer rather 
than a farmer. The decision may have 
been based upon the idea prevailing 
among youth in most rural communities 
that the city man is in some way su- 
perior to the farmer, and that to be 
ambitious is to go to the city. Or the 
decision may ha\e been based on a real 
and very strong dislike for farm life. 
Or it may have been based upon a real 
longing for the city. But in most cases 
the decision was made without a knowl-

THE CASE OF THE 

Expanding Spandrel 



Night and day, winter and summer, vear after 
year, for more than twenty-six years aluminum 
spandrels (the vertical area between mndows in 
skyscrapers) were exposed to the weather . . . and 
nothing happened. 

That was proof enough for the architects. 

Proof that Alcoa Aluminum castings used for 
spandrels stood up in all kinds of weather, resisted 
corrosion, kept up their good appearance, never 
needed maintenance. 

"Aluminum works so well for spandrels," 
reasoned the architects, "why not expand its use 
. . . make entire walls of it?" They came to Alcoa 
with their ideas. Alcoa engineers had kept pace. 
Designs and methods for making complete walls 
were ready. New ways had been found to make 
aliuninum cheaper and more useful. 



Today you will see aliuuiuum-clad buildings 
going up in every part of the country. These 
buildings are quick and inexpensive to build. Their 
aluminiun walls never will need expensive painting 
or repairs. 

This case is typical of the history of Alcoa and 
of the men and women who work for it. While 
aluminiun was proving itself in small applications, 
Alcoa engineers were perfecting the methods for 
large scale production and fabrication Within the 
lifetime of men now living, this companv has 
grown to be one of America's great industries. 
New developments now underway in Alcoa's 
laboratories are pointing the way to even more 
widespread uses for aluminum in the vears ahead.

(.-lific of tlu- nature of the real life and 
work of an engineer. 

Whatever the reasons for your deci- 
sion four years ago, the important ques- 
tion is, "Do these reasons hold?" You 
are face to face with your first job. If 
a careeer is realh planned, instead of 
being permitted to happen, each job 
should be a preparation for the jobs 
which follow. The selection of your first 
job should affect your whole professional 
life. Certainly before such an important 
anil decisive step is taken a man owes 
it to himself to learn the true nature of 
the work which he is about to take up. 

.No problem in mechanics is, to you, 
so important as the problem of your 
career, yet you may have worked all 
night on a problem in mechanics to pass 
a course. Should you not spend a corre- 
spondingly greater time selecting your 
career since it affects the success and 
happiness of \<)in- whole life? 

The college course is selected during 
or before the freshman year, but your 
occupation for life should not be finally 
selected until the senior year or possi- 
blv a >ear or two after graduation. This 
implies that a man nia\' properly take a 
technical or professional course and then 



engage in some other wiiolh unrelated 
activity. 

It's Sol I'lKj Ltitf lit (Ihanytl 
Can a civil engineer graduate justifx' 
entering the ministry? May a mechani- 
cal engineer go back to the farm without 
being a qiu'tter? Both questions have the 
same answer, yes — under certain condi- 
tions. 

If, after graduating as a ci\il engi- 
neer, a ni;in is thoroughly convinced 
that the only riling he can do and be 
happy is to preach; if he knows that he 
can preach; and if he can be content 
on a preacher's income, then, I sa\', he 
should be a preacher and not a ci\ il 
engineer. 

Likewise, if after graduating in me- 
chanical engineering, a man is thorough- 
ly convinced that the only thing he can 
do and be happy is to farm; if he knows 
that he can farm; and if he can be con- 
tent in doing a farmer's work and living 
a farmer's life, then, I say, he shoidd 
go back to the farm and not be a me- 
chanical engineer. And no man has a 
right to call him a quitter. 

Vnur \ lars Lostf 
Will not leaving the profession for 
which one's college course has prepared 
him be equivalent to scrapping his col- 
lege work? Even if this were so, it is 



better to throw away four years than to 
spoil the remainder of a lifetime. 

But such a shift does not mean scrap- 
ping a college course. Preparing for a 
particular profession is only one of many 
objectives of a professional or technical 
course. E\er\- college course should teach 
the student to think clearly, to write 
and speak correctly, to learn scientific 
facts and laws, to collect and deduce 
data, and to apply scientific knowledge 
to the solution of problems. These aims 
arc common to all college courses and 
they compose the major part of the prep- 
aration for all professions. 

A civil engineering course that would 
not help a farmer, a banker, a lawyer, 
or a merchant would be of little use to 
a civil engineer. It would be folly to 
argue that to prepare for one profession 
and to follow another curtails no loss; 
but while there is some loss, the loss is 
small. 

The danger of advising, or even ad- 
mitting, that it ma\' be proper, under 
certain conditions, to follow one profes- 
sion after having prepared for another, 
is that a man who is really a quitter 
may use the advice to justify jumping 
from one occupation to another. It must 
be clearly understood that a man is ad- 
vised to change from one profession to

Who Invented 
Eli Whitney? 




In 1793 Eli Whitney helped a growing nation take 
another step in the direction of greatness. Inventions 
like his made and keep America great. But what 
does the greatness 'of American inventors and tech- 
nology prove? 

It proves that Americans are better trained than 
other people in the scientific and technical funda- 
mentals so necessary for the continuing progress 
that has kept America the world's greatest nation. 
In America, the finest textbooks ai'e available to all. 
This is the background for the technological ad- 
vances that raise one country above all others. 

Many of the books from which you learn your 
fundamentals bear the McGraw-Hill imprint. 
McGraw-Hill is the world's largest publisher of 
books for technical reference and instruction as well 
as for advanced research and study. 



The discoveries of today are the fundamentals of

The advice to change is not offered 
to the man who is disgruntled, to the 
man who finds his present work hard 
ami tedious, or to the man who is a fail-

agreeable features may be due to a poor 
selection of the occupation, but they may 
also be due to the individual. If the lat-

What is wanted is not merely a 
change from one occupation to another, 
hut a change from one occupation unfor- 
tunately chosen in ignorance to an occu- 
pation chosen with the full knowledge 
of the occupation and of your own abil-

There are round holes and round 
pegs; likewise square holes and .square 
pegs. The round pegs should be in the 



round holes and the square pegs should 
he in the square holes. If you are a 
square peg in a round hole you should 
change. 

But before you jump out of the round 
hole, be sure that you are reall>' square; 
,uul be sure that the new hole is like- 
wise square. Also remember that a 
square peg often can easily be rounded.

He's a Square D Field Engineer. 

He speaks the language of many indus- 
tries because his full-time job is working 
with them . . . helping them find "a better 
way to do it." 

Through a staff of such Field Engineers 
located in more than 50 offices in the 
United States, Canada and Mexico, Square 
D does this three-fold job: Designs and 



builds electrical distribution and control 
equipment in pace with present needs — 
provides sound counsel in the selection of 
the right equipment for any given appli- 
cation — anticipates trends, speeds de- 
velopment of new methods and equipment. 
If you have a problem in electrical dis- 
tribution or control, call in the nearby 
Square D Field Engineer. He makes a lot 
of sense in finding "a better way to do it."

coupled to an amplifier system and an

system the focal point can be located 
at any desired section of the ner\e which 
is contained in the holder. 

The electrical stimulator, iiiciitioncd 
above, is provided to activate the nerve 
so that it reacts to ultrasonic sound and 
sends an electrical impulse into the oscil- 
liscope and is observed by the camera.

able amplitude and time duration i>

values of pulse duration and repetition 
rate can he ohtained chrectlv' from the 
instrument dials. 

The sound duration is the final thin^ 
taken into consideration and is obtained, 
at present, by manual control onh. 
Duration times are varied from 5 to M^ 
seconds. For shorter intervals automatic 
control is necessary. An automatic sys- 
tem is now being developed whereb\- 
ultrasonic excitation will follow electri- 
cal excitation or vice versa with dehu 
times of 50 microseconds to 1 second. 

The apparatus is quite complicated as 
would be expected of this type of re- 
search. The pictures may help to pro- 
vide an understanding of the physical 
setup.

smaller diameter fibers. Kxperiments 
have proved that the larger diameter 
fibers are activated by stimulus intesi- 
ties considerably less than what is re- 
quired to stimulate the smaller fibers. 

At this point it might be wondered 
how the fibers are separated. A re- 
markable mechanism, called a micro- 
manipulator, is used by physiologists to 
do this job of dissecting. 

To date only a few experiments have 
been of much value due to the some- 
what crude construction of part of the 
equipment. Yet, despite this disadvan- 
tage, results of tests completed thus far 
have given an insight as to what might 
be expected in the future. 

Nerve Testing 
In one test the leg nerve of the craw- 
fish was stimulated electrically slightly 
above the threshold of the most excit- 
able fiber with a 0.1 millisecond pulse, 
once per second. When the sound was 
first turned on the effect produced was 
a decrease in the latent period. This 
was indicated by the movement of the 
spike (as noted on the oscilliscope) 
to the left. (The latent period is the 
interval of time between the stimulation 
and the reaction of the nerve.) A second 
fiber was also excited because the spike 
height increased and the latent period 
again decreased. When the sound was 
turned off the order of effects was 
reversed. 

In a second test the electrical stimu- 
lator was set slightly below the thresh- 
old of the most excitable fiber — the 
sound intensity remaining the same as 
in the previous tests. The oscilliscope 
indicated that the same general pattern 
as in previous the test was obtained. 

When the electrical stimulator was 
set at a le\el of 75 per cent of the most 
excitable fiber, a single fiber response 
didn't occur until after 8 seconds of 
ultrasonic irradiation ; and no other 
fiber responded during the time of irra- 
diation. 

Before conclusions can be drawn from 
this last statement more information on 
threshold changes has to be obtained. 
When no electrical excitation was ap- 
plied, the activity of the nerve increased 
greatly when irradiated to sound, and 
decreased when the soiuid was turned 
off. 

Fr(j/j Leys 
When the frog sciatic nerves were 
tested somewhat different results were 
obtained. In one test the spike height 
of .5 inches on the oscilliscope was 
obtained by adjusting the electrical stim- 
ulator. The nerve was then irradiated 
and the spike gradually increased. After 
the sound was turned off the spike 
height decreased to the original state. 

The results from these tests on the 
nerves indicate that the return to the

How to improve 
a wood hog's appetite 

The wood hog shown here chews up logs for paper 
pulp like a giant pencil sharpener. As they chip away 
at the logs, the revolving cutter knives impose heavy 
shock loads on the bearings. To carry these shock 
loads, engineers specified that the cutter shaft be 
mounted on Timken" tapered roller bearings. Due 
to the line contact between the rolls and races, 
Timken bearings have extra load carrying capacity 
—take the heaviest shock loads. 



Here's how engineers use 

TIMKEN bearings for heavy 

shock loads 

To give extra support to the wood hog's main shaft, 
double-row Timken bearings are used. The tapered 
construction of the rolls and races enables Timken 
bearings to carry both radial and thrust loads in any 
combination. Shafts are held in rigid alignment, end 
movement eliminated. Because Timken bearings 
permit the use of effective closures, lubricant stays 
in and dirt and moisture are kept out.

LOOK FOR THIS RIDGE 




AND 

YOU FIND A REASON 



• There is more than mere identification value in the 
ridge you see on Okonite wires and cables. The ridge is 
proof that the insulation has been folded around the con- 
ductor by the well-known Okonite strip insulating process. 
This method permits inspection at all times during the 
application operation. It assures the perfea centering of 
conductors so important to the avoidance of electrical 
failures. 

The ridge is a permanent mark of an Okonite cable. It is 
still prominent after the final vulcanization in a metal mold 
that insures equal transfer of the heat throughout ever>' 
portion of the insulation. The Okonite Company, Passaic,

WHATMAKBS TBLEl/ISION SO CLEAR? 



"Lots of tilings, Jackie! But mostly brains. The brains of men who know how to make electrons behave in 
tubes. Electrons are tiny particles of electricity. They're boiled out of metal wires by heating units. Much 
the same way as an electric stove boils water. But if the heating unit isn't right, everything goes wrong." 




"The tube people are smart, son. They 
make sure the heatiiic units give oft the 
right heat anil last longer by coating 
them with a fine Norton refractory. 
Alundum 38900 grain, we call it. It's 
so fine that ten grains end to end equal 
the thickness of a piece of paper. 



'Alundum refractory grain is great stuff. 
Its melting point is 2015°C. That's real 
hot! Made into corrugated baffle plates, 
it doubles the efficiency of enameling 
ovens. That's why the surfaces of such 
things as refrigerators and electric stoves 
come so hard and smooth. 



"Some people know Norton only as the 
world's largest maker of grinding wheels 
and machines, Jackie. But refractories 
in many sizes, shapes and materials are 
important Norton products, too. They're 
used in kilns, furnaces and ovens when- 
ever industry wants to get the most out 
of high temperatures . . . safely." 




'So, you see, son, from 
television tubes to re- 
frigerators, Norton Products help make 
all kinds of products better. That's why 
the experienced heads and willing hands 
that make up the Norton team try a little 
harder to make Norton products better."

Many of the engineers on campus be- 
come acquainted with the plant via an 
.M.K. course which has an experiment 
requiring each man to be at the plant 
one or two hours for an inspection trip. 
Data are taken on the operation of the 
plant for a 24-hour period and a formal 
report is made. 

The plant steam and electric load has 
grown tremendously since 1941, and it 
is now ready for its second addition. 
The fourth boiler and third turbine- 
generator was added during the 1947-

"SOLO" PERFORMANCES 



To keep inflation out of electric power costs 
in the face of steadily rising construction and fuel costs, 
electric utilities are showing a growing preference for one- 
boiler-per-turbine operation when providing additional electric 
generating capacity. 
Success of this type of cost-saving operation calls for an extremely 
reliable supply of steam — boilers that will stay on the line day after 
day, month after month. That B&W Boilers are fully measuring 
up to this exacting requirement of modern central stations is 
indicated by the fact that 79 units for one-boiler-per-turbine installa- 
tions without high-pressure cross connections are now in service or 
on order. Together these boilers supply the steam requirement for 
over 4,000,000 kw. of generating capacity. Operating records show 
that most of these boilers are giving uninterrupted service for eleven 
months or more, being taken out of service only for the required 
annual inspections. 
Dependable performance has been a distinguishing asset of B &W 
boilers for over 80 years. It is a foremost reason why B&W steam is 
still a leading choice for making low-cost power more abundant 
all over America today.

PROBLEM — You are designing a machine for 
doing finishing operations on the production line, 
such as grinding, polishing, buffing, etc. Your prob- 
lem is to provide a drive that permits the grinding 
or polishing v/heel to be moved around freely v/hile 
it is running. Hov/ would you do it? 

THE SIMPLE SOLUTION — Use an S.S.White 
pov/er drive flexible shaft to transmit rotary power 
from a suspended or pedestal-mounted electric 
motor to the handpiece which holds the finishing 
wheel. This gives you a portable unit that permits 
the wheel to be readily manipulated to reach all 
points. 



This is just one of hun- 
dreds of power drive and 
remote control problems 
to which S.S.White flex- 
ible shafts are the simple 
answer. That's why every

CARBON MONOXIDE... 
FRIEND OF MAN 

Thanks to high-pressure synthesis^ h now leads a useful life 



To the man on the street, carbon 
monoxide is just a poisonous gas that 
sometimes causes tragic deaths when 
it escapes from the exhaust of an 
automobile or from a poorly tended 
furnace. 

Outside of the chemical field, few 
people are aware that, properly used, 
it is a very real friend of man. In the 
last 25 years, during which catalytic 




A. H. Emery, Jr , ,1/ s Chi- M.I.T. '49 and 
M. J. Ro. ,li I, I'h n Org , Michigan '40 in- 
specting a high-pressure batch reactor taken 
from the shaker tube assembly after a run to 
make 3y5^5-trimethylhexanol. 

and high-pressure chemical tech- 
niques have been highly developed, 
carbon monoxide has become a key- 
stone of industrial synthesis. 

Scientists have found that under 
the proper conditions of high press- 
ure and temperature, carbon mon- 
oxide, in combination with other 
substances, can be converted to a 
variety of useful products. These or 
their derivatives range from an acid 
used in tanning hides to the spar- 
kling plastics in milady's boudoir. 



You'd hardly associate carbon mon- 
oxide with anti-freeze. But at tem- 
peratures from 300 to 450°C. and 
under pressures of 1500 to 15,000 
pounds per square inch, carbon mon- 
oxide and hydrogen unite to form 
methanol — a colorless liquid from 
which is made "Zerone" anti-rust 
anti-freeze for automobiles. From 
methanol and carbon monoxide as 
raw materials, ethylene glycol for 
"Zerex" anti-freeze is produced. 

Plastics and Anti-Freeze 

Methanol is used also to make a 
large number of compounds such as 
formaldehyde and methyl metha- 
crylate. The former goes into urea- 
and phenol-formaldehyde plastics for 
light fixtures, radio cabinets, hard- 
ware, utensils, and electrical equip- 
ment. The latter is the basic mate- 
rial for "Lucite" acryUc resin with 
its many uses. 




The reaction of methanol with 
carbon monoxide leads to acetic acid , 
which is a well-known industrial 
chemical. By the same synthesis but 
substituting ethanol for methanol, 
propionic acid is obtained. From it 
come the "Mycoban" sodium and 
calcium propionates that retard 
mold and rope in bakery products. 

Synthesis in the Future

120 different items that are partly

pressures. However, the possibilities 
have by no means been exhausted. 
Just recently, for example, chemists 
have been learning how to use car- 
bon monoxide in "up-grading" cer- 
tain petroleum hydrocarbons to give 
interesting alcohols. One of these, 
3,5,5-trimethylhexanol, is prepared 
from diisobutylene by reaction with 
carbon monoxide and hydrogen. 

College-trained men and women 
interested in working in this field at 
Du Pont may share in discoveries as 
outstanding as any yet achieved. 

Because of the wide scope of

in many different fields have oppor-

THE TECHNOGRAPH 




J. he ring test, shown above, is a scientific 
method for determining the modulus of rupture 
of pipe. It is not a required acceptance test but one 
of the additional tests made by cast iron pipe manu- 
facturers to ensure that the quality of the pipe 
meets or exceeds standard specifications. 

A ring, cut from random pipe, is subjected to 
progressively increased crushing load until failure 
occurs. Standard 6-inch cast iron pipe, for example, 
withstands a crushing weight of more than 14,000 
lbs. per foot. Such pipe meets severe service re- 
quirements with an ample margin of safety. 

Scientific progress in the laboratoties of our 
members has resulted in higher attainable stand- 
ards of quality in the production processes. By 
metallurgical controls and tests of materials, cast 
iron pipe is produced today with precise knowl- 
edge of the physical characteristics of the iron 
before it is poured into the mold. Constant control 
of cupola operation is maintained by metal analy- 
sis. Rigid tests of the finished product, both ac- 
ceptance tests and routine tests, complete the 
quality control qxle. But with all the remarkable 
improvements in cast iron pipe production, we do 
not forget the achievements of the early pipe 



founders as evidenced by the photograph below of 
cast iron pipe installed in 1664 to supply the town 
and fountains of Versailles, France and still in 
service. Cast iron pipe is the standard matetial for 
water and gas mains and is widely used in sewage 
works construction. Send for booklet, "Facts About

THE TECHNOGRAPH 




These glass eggs make TNT behave 



The traditional way of shooting an oil well 
is to lower cans of nitroglycerin into the hole 
and explode them at the depth where traces 
of oil have been found. 

Now, petroleum engineers, using double- 
ended glass cones made by Corning, can 
shape and direct these explosions to pene- 
trate oil-bearing rock with a rifle-like charge. 

These pointed glass eggs, with shells no 
thicker than a pop bottle, are set in the ends 
of cylinders of TNT and the charges are 
arranged in a case for lowering into the well. 

Miraculous as it may seem, the glass egg — 
as it is liquefied by the explosion — acts as a 
gun barrel to aim the tremendous blast and 
concentrate it in a thin stream. The TNT 
charge — shooting directly outward — rips a 
hole in the rock to let the oil flow. 



And this hole penetrates some sixteen times 
farther than one made by an unshaped 
charge. 

Because they are sometimes used in wells 
two miles or more deep, these Corning glass 
charge-directors are built to withstand heavy 
subterranean pressures. 

And although the eggs are hollow, they'll 
stand up under a pressure of 20.000 pounds 
per square inch. 

But if that seems strong to you, we'd like 
to point out that a one-inch cube of this 
same glass has a compressive strength of 
250.000 pounds. 

Throughout industry, Coniini,' means re- 
search ill !,'/(;.si because a multitude of Corn- 
ing developments — such as finding ways 
to increase its strength — have helped make 



glass one of today's most versatile engineer- 
ing materials. 

You'll find — when you're out of school 
and concerned with planning new products 
and processes, or changes in old ones — that 
it's a good thing to keep s^Uiss in mind. 

Then, we hope you'll call in Corning be- 
fore your planning reaches the blueprint 
stage — to learn how this material, which has 
so many varied uses, can best serve you.

by taking the short way over a bridge- 
give a thought to the days when the 
bridge wasn't there, when people had to 
take the long way around. 

Right then would be a good time to

build the things that make America great. 

The steel industry offers hundreds of 



possibilities in this direction. From the 
mining of raw ore to the fabrication of 
the finished product, steel-making is di- 
rected by technically-trained men. Spe- 
cialists in every phase of engineering 
play a vital role m the many and varied 
steps in making steel. Thousands of 
other engineers supervise the transfor-

like this mighty bridge. 

Linited States Steel recognizes the 
need for carefully-trained specialists and 



pays particular attention in its educa- 
tional program to the development of 
college graduates and other technically- 
trained men. This program has as funda- 
mental objectives providing employees 
a sound foundation for advancement and 
assuring them opportunity for maximum 
personal development. 

The training program in United States

Great Names are built on 
Solid Foundations 



Individual reputations, or futures, 
like that of a business, are built on 
solid foundations. So let's examine 
the basis of a solid foundation. 

Suppose you had a problem . . . 
required some kind of power to 
help hurl a jet plane into action 
from a ship. That was a critical 
problem of the Navy in wartime. 

They came to Westinghouse, 
where they knew they would find a 
strong foundation in power equip- 
ment. And Westinghouse engineers 
came up with the answer — a motor 
1,400 feet long that lies perfectly 
flat . . . never turns . . . has no shaft 



. . . that looks like a railroad. And 
it works . . . sends a plane into the 
air at 117 miles per hour. 

This same daring spirit developed 
a 65,000-hp motor to pump rivers 
of water for a vast irrigation project, 
20 percent larger than any motor 
previously built . . . and a motor so 
small that you can hold it in your 
hand, and that runs at the almost 
unbelievable speed of 65,000 rpm 
to do another highly important task. 

This pioneering spirit prevails 
throughout Westinghouse, whether 
it's a need for motors, railway loco- 
motives, gas turbines, steam power, 



elevators, radio, electronic devices, 
x-ray machines, household appli- 
ances, plastics, lamps, lighting, 
atomic power development, or a 
need in any of the hundreds of other 
channels in which Westinghouse 
carves its name with engineering 
achievements. 

Important responsibilities can 
only be placed on strong founda- 
tions. At Westinghouse, programs 
of training and education strengthen 
engineering backgrounds so that 
technical men can assume vital roles 
in a dynamic organization that 
stakes its future on the commitment:

Ram-Press 

A line (il l(i\v-cost iiiii\crs;il rani-typc 
liydraulic broaching machines priicd far 
below the cost of single-purpose lani- 
r\pe machines has been announced hy 
Colonial Broach Companx. 

The new ram-press machines nia\ he 
used interchangeably for all conventional 
broaching operations, including: 

1. Surface broaching 

2. Internal push-broaching 
,v Slotting 

4. Pr<'ss-w(u-k 

ThcN are available in 4-, (>-, and 10- 
ton capacities and come with 24- and 
,^(i-inch strokes. 

The ram-press is a high quality 
broaching machine throughout. Columns 
arc of heavy steel, using a welded con- 
struction, with hardened and ground 
ways the full length of the column for 
the ram slide. 

The h>ilraulic system provides excess 
capacity for occasional overloads. Cylin- 
der construction is such as to simplify 
maintenance and enable replacement of 
cylinders separately from the ram, if 
this should ever be necessary. 

A simplified hydraulic hook-up also 
eliminates the necessity of cored passages 
leading to the cylinder in the machine. 
Piston rods for operating the rams are 
located in a protected position and are 
never exposed to accumulation of chips 
or foreign matter. This construction fur-

lic broaching machine has a wide 
variety of uses. (Courtesy of Colo- 
nial Broach Co.) 



thei' aids in eliminating chance of leaks 
and provides excellent protection for the 
cylinder packing. Pistons arc of close 
gi;iin cast iron with aut<iniotive t\pe 
rings. 

The coolant system has its own sepa- 
lateK motorized impeller type pump, 
eliminating belts, pulle>s, etc. Separate 
start and stop controls are provided for 
the coolant and h.vilraulic pumps. Stroke 
adjustments can be made quickly and 
accurately by means of externally lo- 
cated collars on a trip rod located along- 
side of the ram. These controls provide 
automatic stopping of the machine at 
the top and bottom of strokes. 

A large bracket bolted to the ram 
face is designed for use in internal push- 
broaching and for single or multiple 
assembly and press-work, etc. Manual 
operating controls are simple and prac- 
tically foolproof in operation. The ma- 
chine is ideally suitable for shops where 
job runs of parts are to be put through. 

Machines can be furnished with spe- 
cial circuits for operating receding tables 
or fixtures where demanded by certain 
surface broaching operations. Special cir- 
cuits can be furnished for automatic 
clamping. 

Bounce Kills Jounce 

Hoiiiuing |inrt\, now wideh used in 
golt balls and in devices which automa- 
tically level furniture, has been put to 
work in a new job. This time it's pro- 
tecting the delicate instruments of V-2 
rockets fired at White Sands. 

Wrapped in a half-inch coating of 
bouncing putty, motion picture cameras 
hardlv mind the crash of the huge rocket 
after their liiindi ed-niile plunge b.ack to 
earth. 

This silicone "putty" flows like ordi- 
nary soft glazing putty. Rolled in a ball, 
however, it has a lively bounce. It's so 
bouncy, in fact, that in several instances 
putty-wrapped instruments have survived 
to tell their stories e\en when V-2's 
have come apart 50 miles up. 

Self-Locking Set Screw 

A new self-locking set screw and ad- 
justing screw called Zip-(irip, that does 
not require any lock nuts, wires, imping- 
ing locking screws, or deformed or riv- 
eted threads, is being produced by Set 
Screw t<v: Mfg. Co., Bartlett, Illinois. 

The new Zip-Cirrip set screw is specif- 
icallv designed for applications in which 
excessive vibration is a factor, aiul for 



regulating and adjustment applications 
in which instantaneous locking at a pre- 
cise point is desired. 

Zip-(irip is said to be the first set 
screw to have triple-locking action by a 
combination of interference fit, tension, 
and locking of the .set screw against the 
shaft or other part. As the cutaway illus- 
tration shows, the lower part of the 
Zip-(uip screw (H), which enters the 
hole first, has a standard thread. 

The upper section of the screw (A), 
designated as the "activating area," has 
a larger pitch diameter in the thread 
section; this creates an interference fit 
or expansion effect against the thread 
flanks. This results in a tension or op- 
posed-fmce action, causing the thread 
section of the upper part to be drawn 




The principle of the Zip-Grip self- 
locking set screw is shown in this 
illustration. (Courtesty of Set Screw 
& Mfg. Co.) 

downward and that of the lower part to 
be drawn upward, in the direction of 
the screw's locking action, against the 
shaft. 

Among the advantages claimed for 
Zip-Grip are reduction of production 
costs on tapping operations, as no closer 
fit than Class Two is required, and the 
extra tapping for counter-locking and 
extra set screws is eliminated ; increased 
assembh speed because Zip-Cirip screws 
are quickly inserted and tightened with 
no time taken up by adjusting outside 
locking devices ; and improved perform- 
ance due to the elimination of "creep- 
ing" in \ibration applications and in- 
creased speed of adjustment on regulat- 
ing screw applications. 

The new self-locking screws are avail- 
able in all metals, including soft or hard 
steel, case hardened or heat-treated steel, 
stainless steel, brass, bronze, or alumi- 
num.

Our erstwhile brethren at the Pier in 
good old Chi-town were greeted with 
some good news the other day. The en- 
gineering and architecture students who 
aie "eligible" to transfer to the L rbana 
campus next semester were preregis- 
tcre.l. 

Representatives from the main cam- 
IMis went to the Pier on December iS 
to give the students there all the neces- 
sary information about courses, curricu- 
lum, etc., and to assist in the registering. 
1 )ean Tre/.ise, at the Pier, pointed out 
that the new s\stem will enable each 
student to ha\e indiviilual attention and 
consideration so that he will know what 
he's getting into before it's too late. It 
will also help the departments here on 
the campus in that they will know be- 
forehand how many |ieople will be com- 
ing from the Pier. 

.\ total of 120 engineers and .i5 archi- 
tects will be coming liown for the spring 
semester, assuming that they all pass 
the finals! When the\ get here, the 
transfer students will ha\e nothing but 
their study-lists and fees to complete. 

Pie-registration for all other engi- 
neering and architecture students at the 
Pier will he held before the final exam 
ses.siou. 

FlASH THE BoNE'lARI) 

Nestled behind the new E. E. lab on 
engine campus is a small plot of ground 
surrounded by a wire fence. No, it's not 
the stockade for those who flunk thermo 
exams. It's a part of the Boneyard h\- 
drologic stud\ dealing with rainfall-run- 
off relations and eva|ioration rates from 
water surfaces. 

The apparatus enclosed b\- that fence 
is something new that is being developed 
here for the determination of evapora- 
tion rates. 

Of primary interest to localities whose 
water supply comes from reseivoirs is 
the rate at which evaporation occurs. 
( )ne method for determining this rate 
is by use of a pan of water equipped 
with a hook gage. Obviously, this means 
will f;nl when the temperature drops 



and ice forms. .Anothei' disadvantage is 
that the effect of air cunents cannot 
be determined. 

Hy the use of equations which are 
beyond the scope of this article, it is 
possible to relate the evaporation rate 
to vapor pressure data. The vapor |ires- 
sure data may be obtained from dew 
point data; this is the pmpose of the 
mast towering above the enclosLire. 

At the top of the mast is a cell which 
is surrounded by a hygroscopic salt 
which is further surroimded by a wire. 
As long as there is no moisture present 
in the salt, there will be no current 
flow in the wire. When there is some 
water absorbed by the salt, a current 
flows in the wire which is proportional 
to the humidity of the air (which may 
further be used to find the dew point 
of the air). Thus it is possible to record 




The cabinet encloses the dew point 
and dry bulb temperature record- 
ers. In the foreground are the 
evaporation pan and the anemom- 
eter. (Photo by Joe Graham) 

the liew point directh' by measuring 
the current. 

This is actLiall)' what is done b\ the 
complete unit atop the mast. .\ thermo- 
couple is placed in the cell such that the 
current caused by the water content of 
the salt will heat the couple. Thus, a 
current is established in the thermo- 
couple leads that is indirecth' related to 
the dew point of the air at the top of 
the mast. The leads from the couple run 
down the mast to a continuous recorder 



which reads directly in dew point tem- 
peratmes. The dry bulb temperature of 
the air at the top of the mast is recorded 
on the same instrument. 

Some difficulty has been met in try- 
ing to record the dew point of the air 
near the base of the mast, but latest 
reports indicate that the work being 
done is proceeding in the right direction. 

The 4' X 10" standard class A weath- 
ci- biu-eau evaporation pan is used at the 
station to compare this new method with 
the old method of determining dew 
point 

A weighing-type rain gage is used to 
measure any and all precipitation. The 
fence was deemed necessary after some 
little boys added their two-cents worth 
of precipitation. This rain gage is super- 
ior to the old tipping-bucket gage since 
ice formation will not affect the deter- 
nu'nations. 

To calibrate the apparatus at the sta- 
tion, an extremely sensitive microhygro- 
graph is used. This instrument is so 
sensitive it will register the humidity 
change caused by a human breath blown 
toward it. 

The precipitation determinations are 
being used in conjimction with the flow 
measurements made bv the weir in the 
Honeyar.l behind CEH.

FINAGLE FACTOR 
FUNCTIONS 

itif John lluhfr, Aff.K. '.12 



It is painfully apparent that the text- 
bonks in use by this University are lack- 
ing in one very important item — said 
item being a discussion of the finagle 
factor. 

Every engineer will agree that it is an 
extremely useful little factor and tliat 
everyone should become quite skilled in 
its use. Why, then, have the frustrated 
professors who compose our texts been 
so lax as to forever omit it? Maybe they 
fear the consequences of making the use 
of such a potent tool common knowl- 
edge. The only foreseeable consequence 
is that they might lose their jobs. 

Since we have no jobs to lose, stand 
b\' for finagle factor education. 



With final exams peeking In the 
window, It's time to buckle down 
and learn a few tactics, If not 
techniques, for pulling the points. 
After making a complete survey 
of maneuvers, John has brought 
forth that oft-quoted, but little- 
used item, the finagle factor. 

To completely describe its po- 
tentialities would fill a book, or at 
least this magazine (which might 
not be a bad idea). The subtle 
treatment of this subtle subject 
seemingly strikes some as salva- 
tion from stuffy assignments. 



The first logical step is the determina- 
tion of a suitable symbol to designate 
tile use of the fudge or finagle factor. 
This in itself is no trivial task, for it 
should be a symbol that is easily written 
and just as easily understood. It is also 
liifficult to find a letter or symbol that 
doesn't already have a multitude of 
meanings. F seems to be an obvious let- 
ter to use but it is alread\' greatly o\er- 
worked b>' being used to designate force, 
fine, friction, and many other factors. 
(It is also too close a companion to 
one's alphabetical grade.) 

Through the same incomprehensible 
reasoning that the mathematicians ap- 
parently used in choosing delta to equal 
a change, we could undoubtedly arrive 
at an equally unrelated symbol for fina- 
gle; but for the sake of clarity and for

merely incorporate the symbol -^ 

Now to slaughter the main issue. It 
would indeed require too much space to 
iliscuss the varied and sundry applica- 
tions of "^ outside of a book, so I will 
merely try to enumerate the basic funda- 
mentals of usage. 

First, let's make use of -<L_ when we 
aiii\e at a calculated answer that is 
ijh\ ioush' in error. An example might be 
a finding of HA'~> ft as the necessary 



iieight of a bottle of gi\en circumference 
to holil enough beer to keep one engineer 
liaiip\' one evening. This answer, though 
ni;i\'be not so obviously in error, would 
|irobably suit the instructor better if it 
were in different units or had the deci- 
mal point changed. 

It is not necessary to check through 
the calculations to discover the error 
when all one must do is make the 
changes that will render the answer 
more logical and write after it -^ 
Ans. This notation stands, of course, 
for finagled answer. The instructor will 
appreciate yoin' ingenuity and, if he has 
.1 sense of humor, will not mark it incor- 
rect. 

I'ossibh the next most important use 
(if -^-- is concerned with laboratory re- 
poits. Suppose we are asked to experi- 
mentally substantiate K r o c k ' s Law 
which states that the coefficient of ad- 
hesion between leather and paper is 
.(100137. Hut, after running many tests 
concerning student finances and burning 
out our sliderule bearings, we arrive at 
tile coefficient value of .000042. 

Due to some inborn fanaticism the 
lab instructor will swear by Krock and 
will deem your findings nearly a hun- 
ilred percent in error. Such an error will 
certain!)' do your grade no good so it is 
best to start with a reasonable answer of 
about .000135 and work backwards. H\ 
this method, more appropriate data will 
be discovered. Lab instructors abhor 
erasures so it is best to merely mark one 
line through the erroneous data, insert 
more pertinent values below, and write 
"^^ after the correction.

closely resembles the realm of what was

is constantly lengthening man's life span, 
guarding his safety, increasing his con- 
veniences and his comfort, saving his 
money, bettering his health, and en- 
larging his view of the world. 

Here at the University of Illinois the 
Engineering Experiment Station is cer-

KstdlilhhiiunI 'if ihc Sliitioii 
The need for an experiment station in 
the College of Engineering was recog- 
nized long before its actual establish- 
ment 46 years ago. Investigation and 
studies of engineering, manufacturing, 
railwa\s, mining, and other items of 
industrial interest were badly needed. 

Such a station could also improve 
teaching processes and develop new ma- 
terial for classroom and laboratory. This 
would help to keep the University work 
in step with progress in engineering and 
industry. It could also provide a means 
lor eiiucating and training graduate stu- 
dents in methods of conducting research. 
Much of the credit for the conception 
of the idea and the establishment of the 
station belongs to Professor L. P. Breck- 
inridge, at that time the head of the 
Department of Mechanical Engineering.

an effort to secure federal action to 
establish engineering experiment stations 
similar to the agricultural experiment 
stations already in existence. Failing in 
this, he proposed that the University 
establish an Engineering Experiment 
Station with State funds. 

In December, 1902, the Board of 
Trustees of the University of Illinois 
included in their list for legislative ap- 
proval a separate bill requesting funds 
to expand the activities of the College 
of Engineering. Faculty, alumni, and 
manufacturing and construction inter- 
ests joined in the support of the bill. 

In May of the following \ear, the 
(R'lieral Assembly passed a general bill 
providing $15(1,000 for the College of 
Engineering. Of the total, $43,000 was 
allotted for the purchase of land and

and the remaining $77, ()(.)() was set asi<le

Thus, by an act of the Board of 
Trustees of the University of Illinois, 
the Engineering Experiment Station 
came into existence on December <S, 
1903. This station was the first of its

Before an\- attempt is made to deter- 
mine the time required in engineering 
school, it woidd he well to investigate 
the things that must be accomplished by 
the student in that time. An evaluation 
of engineering education as a whole will 
point out those minimum educational at- 
tainments which the candidate for the 
R.S. degree in engineering must ha\e 
mastered before he is prepared for grad- 
uation. 

An engineer is a human being and a 
citizen before he is an engineer. As such, 
there are certain fiuidamental studies 
which he must master. 

Of these studies, the one that fills the 
most basic need is the study of commu- 
nications. The engineer, as well as the 
rest of men, must be proficient at read- 
ing, speaking, writing, and equally im- 
portant, listening. This is true not only 
for his own progress and well being, but 
for that of his fellow men, country, and 
world. Before any problem, within or 
without engineering, can be solved or 
e\en grasped, it must be put into some 
mutually understood language. For the 
abo\e reasons then, it is necessary that 
the student be thoroughh' trained in the 
transmission and reception of written 
and verbal information. 



It has been the custom for the 
TECH to publish the first-place 
essay of the Tau Beta Pi pledge 
competition. Writing a non-techni- 
cal, editorial-type paper is one of 
the initiation requirements of this 
all-engineering honorary. 

Vince McDonald's winning essay 
asks a question of considerable 
engineering interest, but it makes 
no attempt at a specific answer. 
Instead, a general explanation of 
the important factors of engineer- 
ing education is presented. Need 
of four or more years is depend- 
ent not only on the school but' on 
the man. 



One section of his education should 
impart a working knowledge of things 
iiistorical. Not only national and world 
history, but also the historical landmarks 
of philosophy, literature, music, and art 
should be known and appreciated.

sired for everyone, it is essential in engi- 
neering. The engineer must be able to 
think, and he must be trained to think 
efficiently. Undoubtedly, this is the most 
important phase of his technical training. 
The successful analysis and evaluation 
of data cannot be handled by many for- 
mulae and a group of pre-set circum- 
stances; they depend on agility, flexibil- 
ity, and logic in thinking processes. 

For an aid to thinking the engineer 
must be equipped with a sufficient 
background in mathematics. Mathemat- 
ics will not only reduce the labor of his 
thinking, but it will provide an acces- 
sory to thinking, and by means of its 
symbolism, open a new language more 
precise, clearer, and more logical than 
English. 

Further, the engineer must be tr;iined 
efficiently to gather and record data. 
He must have a thorough grounding in 
the fundamentals of all engineering with 
an emphasis on his selected field. Finally, 
he must have a real and deep interest in 
engineering. 

Thus, the important qualifications 
ha\e been listed. The more thoroughly 
these qualifications are filled the better, 
but some degree of mastery of them is 
essential before the student is ready for 
his degree. 

So, then, to the question, "Should 
engineering be a five year curriculum?" 
we must answer, "Yes, if it takes that 
long — longer if necessary!" 

However, the student entering an 
engineering school as a freshman should 
already have much of the ground work. 
Actually, education, or engineering edu- 
cation in this case, is started at home, 
begins to be formally directed in grade 
school, and expands in high school. 

Thus, it could be said that "engineer- 



ing school" also encompasses the previ- 
ous twelve years of more or less formal 
education. Certainly, it may be said that 
"engineering training" does include 
them. 

If the grade and high schools effici- 
ently perform their work, the task 
awaiting the college is merely a further 
enlargement of previous work, and the 
necessary and desired status could be 
attained in a relatively short period of 
time. But, if previous schooling has been 
weak, or has failed almost completely, 
the college must then fill in the \oids 
to bring the student up to the desired 
level. 

The methods and the precise number 
of hours this process will require must 
be determined by the properly trained 
educators. As has been indicated, this 
time will decrease as the effectiveness of 
earlier education increases. However, 
the previoush' mentioned minimum 
standards must be met, regardless of 
the time involved, if the graduate is to 
be considered an engineer in the full 
sense of the word. 



X-Ray Microscope 

An X-ra\ microscope, which makes 
visible the internal details of materials 
through which light cannot pass, has 
been developed by the General Electric 
Company. 

Future refinements of the .\-ra\ mic- 
roscope, which is at present in the lab- 
oratory stage of development, may re- 
sult in much sharper images and higher 
magnifications than are possible using 
visible light. 

Electron microscopes are the most 
powerful magnifiers in use at the pres- 
ent time. They use a beam of electrons 
rather than light to form an image of 
materials under study. 

The X-ray microscope does not re- 
quire that samples under stud\' be in a 
high vacuum, as does the electron micro- 
scope. Because of this advantage, "it 
may'be possible to examine living mater- 
ials at much higher magnifications than 
ever before." 

Clear, sharp X-ray images, magnified 
10 times have been produced in the lab- 
oratory, and these images have been 
magnified 10 times further by photo- 
graphic enlargement without serious loss 
of detail.

NAVY PIER 



Drawing at the Pier 

By Clarence Niebow, M.E. '51 

Quitf a few changes have been made 
at the pier since the University opened 
its doors in September, 1946. One of 
the chief changes is noted as one passes 
the offices and drawing labs of the (len- 
eral Engineering Drawing Department. 

When we entered the office of the 
engineering drawing department recent- 
ly, the remodeling of this room was 
just about completed. Each instructor 
\\ ill now have his own office. The pur- 
pose of these individual offices for the 
instructors is to give them a pri\ate 
place to conduct consultations with their 
students without undue distraction. 

In the drawing labs there are con- 
necting doors between the rooms. Also, 
in every lab, is a glass enclosed bulletin 
board. These bulletin boards are used 
to display the work of the students in 
orticr to exhibit what constitutes a good 
thawing. The connecting doors were put 
in the labs because of the overcrowded 
(i.E.D. classes. When an instructor 
finds that he has more students than 
desks, he can send some to the adjacent 
rooms. 

The iih\sical impr()\ements that ha\e 
been mentioned are of tremendous aid 



to the students for two reasons: the stu- 
dents can get more assistance from their 
instructors, and they do not have to 
work too close to each other. 

Along with these physical improve- 
ments, there were a few other items 
which caught the reporter's eye. Among 
these items was the weekh' contest that 
is conducted by the department. P^very 
student enrolled in a G.E.D. course is 
eligible to enter these contests. Four 
plates from each section are chosen 
every week by the instructor for en- 
trance in that week's contest. The names 
of the students are covered with tape, 
so that favoritism will not be shown. 

The Judges for the weekly contests 
are students who are enrolled in a 
( I.E.D. class. The basis upon which 
these plates are judged is the lettering.

points a judge can give a plate is 3(1(1 
points. At the end of the semester the 
student from each (i.E.D. class who has 
the highest number of points is to hi- 
awarded a certificate of merit. The pur- 
pose of these weekly contests is to estab- 
lish a competitive spirit among the stu- 
dents, so that better work ma\ con-

Engineering Societies 

By Ronald Sak, Aero.E., '53 
A.S. \LK. 

The ASME has been holding its meet- 
ings at regular two-week intervals. The 
activities undertaken broaden the me- 
chanical engineer's muul in his particu- 
lar field. 

W. W. 1 1 wain, a graduate of the 
I . of I., and now an executive in a 
branch of the International Harvester 
Company, was asked to speak at one of 
the M.E.'s meetings. On Oct. 25, he 
spoke of the maintenance and design of 
his company's foundries. 

During the Christmas vacation, four 
plant inspection tovns in the Chicago 
area were held. The downstate chapter 
of the ASME were also invited to at- 
tend these tours. The companies visited 
were the International Harvester Com- 
pany, Michle Printing Press and Mfg. 
Co., Peoples (las. Light and Coke Co., 
and Continental Foundry and Mfg. Co. 

I.A.S. 

.Movies depicting certain phases of 
aeronautical work and describing the 
problems in this field of engineering, 
are shown at regular meetings. The out- 
standing movie of the month was the 
Boeing Stratocruiser. 

(^n Nov. 23 the group toured 
O'Hara Field, the Air Force Base lo- 
cated at Mannheim Road and Devon 
Street. The group was permitted to 
climb inside a plane and get the feel of 
the controls. Later the group was shown 
the museum which consisted of Ameri- 
can aircraft and captured foreign air- 
craft from World War 11, and Bill 
Odum's V-tailed Beechcraft which were 
awaiting shipment to the Smithsonian 
Institution. 

A base operation officer explained the 
methods of determining weather condi- 
tions in any part of the country and its 
importance to pilots and authorities. The 
machine shop and runway tower were 
also part of the tour. 

A.S.C.E. 
On Dec. 2, 1949 the members planned 
and carried out their annual dance. It 
started at 8:30 p. m. The affair was 
held at Keyman's Hall. Music was pro- 
\ ided by Stan (^erut's Downbeats. A 
\ery good time was had by all.

THE TECHNOGRAPH 



PROF. W. E. HANSON 

I'lom the town of Lyndon, Kansas, to 
till- University came W. E. Hanson, 
associate professor in Civil Engineering. 
But Professor Hanson's path was nor 
direct by any means. 

He received his bachelor of science 
from Kansas State College in 1939. He 
then went to the Petty Geophysical 
Engineering Company to do siesmic ex- 
ploration for oil wells in Texas and 
Oklahoma. In 1940 he went to Howard, 
Needles, Tammen, and Bergendoff in 
Kansas Cit\ , Missouri. There he worked 
as a structural detailcr and designer on 
bridges. 

In February of 1942 Professor Han- 
son came to the University in the dual 
role of graduate student and instructor 
in C.E. He was made instructor in 
(j.E.D. in September, 1942, but in 
October of the following year he en- 
listed in the United States Naval Re- 
serve as an ensign. 

W^hile in the Navy, he had eight 
months of radar training at Princeton 
and M.I.T. After this he spent a year 
ami a half with a carrier air group and 
night squadrons in the Pacific. 

After his discharge from the Navy, 
he returned to this campus in February, 
1946, as an assistant professor. The 
next year, 1947, IVIr. Hanson received 
his master's degree. Last September he 
became associate professor of Civil Engi- 
neering. 

Professor Hanson is a member of 
Sigma Tau, Chi Epsilon, ASCE, and an 
associate member of Triangle. Last 
spring he was voted a most effective 
instructor. He is also a Tcchnoi/raph 
adx isor. 

For the last four years he has written 
the "Structural Engineering Review" 
for the Aiiuriciin 5 larhnk. Last summer 
he taught a refresher coiu'se for engi- 
neers planning to take the examination

for registration as professional engi- 
neers. At present he teaches courses in 
structures and foundations. 

Professor W. E. Hanson is married 
and has one daughter four years old. 
He owns his own lionie in Urbana. 

BILL FLETCHER 

One of the more prominent agricul- 
tural engineering students is William 
Fletcher. Bill has been active in the 
ASAE during his tour \ears at Illinois,

and has also served two semesters on 
the Engineering Council. 

Bill was born on a 16(l-acre dairy 
farm near the village of Herbert, Illi- 
nois, where he has spent most of his life. 
He graduated from Belvidere High 
Scliool in 1943. In November of that 
\ear. Bill went into the Air Force, 
where he became a bombardier. He was 
released from the Air Force in (October, 
1945, a few weeks too late to start the 
fall semester; but he enrolled in the 
L'niversity in February, 1946. 

Bill was secretary of the ASAP' stu- 
dent branch for the fall .semester of 
1947, and \ice president in the spring of 
194S. In the fall of 1949 he was elected 
president of the organization, and is now 
serving as program chairman. He ga\e 
up his bet\\'een-semesters vacation three 
times to work in the annual Farm and 



Home Week lunch stand, opciated by 
the agricultural engineers. 

Bill is very much interested in iiro- 
fessional societies, and adds, "Ever\' en- 
gineer owes it to himself to have at least 
two affiliations: One to his technical 
society and one to his professional soci- 
ety." 

His main interest, however, is soil 
conservation. He would like to work for 
the U. S. Department of Agriculture 
Soil Conservation Service when he grad- 
uates in February. He has worked one 
summer for the Soil Conservation Serv- 
ice. Another summer he worked for a 
canning company, a third with a drain- 
age contractor, and last summer he was 
cmjiloyed by two ci\il engineering con- 
sultants. 

Bill was marrieil in jul\, 194\ while 
still in the Air Force. Mr. and Mrs. 
1' letcher and their three-year-old daugh- 
ter have made a comfortable home in 
I .ist Urbana by enlarging a trailer. Bill 
likes living in a trailer, but doesn't 
I \pect to live in one all his life.

.San, sanitary engineering honorary and 
piofe.ssional fraternity, at a special for- 
mal ceremony held on December 1. Dr. 
Wolman, widely known for his work as 
consultant to the Atomic Energy Com- 
mission and the World Health Organi-

Springfield and Decatur, completed the 
fraternity's activities for the \ear I'H''. 
The first meeting of the new \ear was 
held January 5. 

A.F.S. 

The American Foundrymen's Society 
had its December meeting at the (jen- 
eral Motors foundry in Danville. At- 
tending student and faculty members of 
the AFS left the campus at 5 p. m., 
December 12. on two chartered buses. 

The group ate ilinner in the cafeteria 
at the (i.M. plant. After dinner a movie 
was shown and later the group was 
conducted on a tour of the foundry. 
This plant has a reputation in the mid- 
west for its efficiency and production 
capacity. 

An election of officers and a general 
organization meeting is tentatively 
scheduled for the first week in Jaiuiary. 
All members are urged to attend. An\' 
non-member who is interested in the 
foundry industry or foundry work will 
be welcome at this meeting. 

A.S.C.E. 
Don R. Anderson and James P. 
Sampson were named winners of the 
104') student awards of the Central 
Illinois section of the 
American Society of Civil 
Engineers. The awards 
were presented to the two 
seniors at a dinner meeting 
on December 6. The meet- 
ing was a joint gathering 
of the Central Illinois section and the 
University student branch of the ASCE. 
The awards are made annually on 
the basis of scholarship, promise, and 
activity in the ASCE. Anderson is in 
civil engineering and Sampson is in 
architectiue. 

The speaker at the meeting was A. P. 
Geuss, chief designing engineer of the 
Harza Engineering Company, Chicago, 
who ga\e an illustrated talk on "llie 
l'eten«ell H\ dro-Electric Project." 

M.I.S. 
Every meeting need not be a business 
meeting. That was shown by the Min- 
eral Industries on December IS when 
a ladies night gathering was held. The 
female guests were not submitted to 
usual dull wrangling about new and old 
business. Instead thev were entertained 





by a mo\ ie on the \ ,ist opeiations of the 
Anaconda Mining Corporation. 

The MIS was instrumental in bring- 
ing two speakers to the University for 
the recent and higlilv successful Career 
Conference. 

A.I.Ch.E. 
The chem engineers are giving the 
local cinemas quite a bit of competition. 
At the December 7 meeting of the 
American Institute of

presented a double feature 
program equal in entertain- 
ment \alue to many of the 
current popular movies, 
main feature was in technicolor 
and starred Alan Ladd. It was entitled 
"Unfinished Rainbows" and portrayed 
the progress of the aluminum industry 
from Charles Hall to the present. The 
title of the second film was "From Test 
Tube to Tank Car." 

t)n Jan. 4 movies were shown and 
elections for officers were held. The 
following Friday, Jan. 6, a Ch.E. party 
was enjoyed at one of the campus spots. 

S.A.E. 

The November meeting of the Society 
of Automotive Engineers was held in 
100 Gregory Hall, where the seats are 
a little sofer than those of 319 CEH. 
A dinner for the speaker, officers, fac- 
ulty, and visiting members preceded the 
meeting. 

The speaker was Mr. R. B. Sneed, of 
the Ethyl corporation of Detroit, Michi- 
gan. Mr. Sneed is the technical repre- 
sentative for the Ethyl laboratories and 
acts as liaison officer to the laboratories 
of the various oil companies throughout 
the midwest area. Mr. Sneed gave a 
very interesting and informative talk 
entitled, "The Laboratory and Road 
Knock Testing of Motor Gasolines." 
The talk was accompanied with explana- 
tory slides. The meeting was conducted 
with the speaker first and the business 
last so that non-members could leave 
after the speech. 

During the business session it was 
decided to have election of officers by 
nominating committee and petition — 
with a ballot by mail to consumate the 
election. In this way it is hoped that 
there will be no long dry business meet-

Mighty Midget 
of Microwaves 



This little electron tube is called the 416A. 
It's the verv heart of the latest radio relav 
repeater equipment for telephone and tele- 
vision transmission over long distances. Bell 
Telephone Laboratories scientists designed 
it — with elements spaced five times closer 
than in anv previous microwave tube — and 
maiie the first samples under laboratory 
conditions. 

Could such a tube ever be factorv-produced 
in quantity.'' It seemed almost impossible — 
but Western Electric engineers tackled the 
ticklish problem. Here's the sort of thing 
they had to deal with. 

Between the grid, which controls the How 
of power in the tube, and the cathode, which 



igineers 



produces the electrons, must be a space 6 10 
thousandths of an inch. The oxide coating 
on the cathode must be 5 10 thousandths of 
an inch — no more, no less. The grid wires 
^3/10 thousandths of an inch in diameter 
— must be woumi around the grid frame 
one thousand times to an inch! 

The tiny parts woukl have to be made with 
laboratory precision. Much of the work would 
have to be done under microscopes. All parts 
would have to be kept surgicallv clean — for 
a speck of lint or a trace of perspiration could 
mar the efficiencv of such sensitive tubes. New 
machines wouki have to be designed — new 
techniques developed — people trained to as- 
semble the minute parts with utmost accuracy. 

Could it be done? Well, Western Electric 
is making 416A tubes in quantity today — and 
with an amazingly low percentage of rejects. 




This machine winds wire 1 8 the thickness of a humc 
hair around the grid (arrow) — 1000 turns per inch- 
maintains tension of 60% of wire's breaking strength.

"Ht'll, what's the use ot going to school or 
(himg an) thing! Another two years and we'll 

be right back in there fighting the Reds." 

o\erheard in an engineering design class. 

Mi.ster, your sentiments are not uncommon. 
There are other people like you, from down 
in Skid Row up to America's own diplomatic 
corps, who are soundly convinced that war 
with Russia is inevitable. 

Mister, you don't quite know or under- 
stand why you believe this. You might give 
as one reason, "Everyone says so." That's 
true; people are saying so, because they've 
heard everyone else say so; so then it must 
be true that is what you call "mob logic." 

It begins with a friction in the U.N.O. 
between the representatives of two or more 
countries, Russia and the United States, for 
instance; then, one or two key men may 
rashly or intentionally make a few heated 
statements to the press; then someone may 
begin a few rumors that spread rapidly; 
eventually, a whole nation is infested with a 
war-with-Russia idea. 

Another reason that you might gi\e. Mis- 
ter, is that all the newspapers, magazines, and 
commentators are constantly proclaiming sup- 
posed incidents of Russian subterfuge and 
plots. That's right; that's just what Is hap- 
pening. After mob logic has snowballed the 
importance of a U.N.O. disagreement from 
a snowflake to an avalanche, the publications 
carry on the cry of the pack. Even staid old 
publications, such as Li/? and The Saturday 
Evening Post, are guilty of this give-the-pub- 
lic-what-they-want sensationalism. Little need 
be said about the influence of commentators 
such as Pearson and Winchell, who are capa- 
ble of making a national disaster out of a dog- 
and-fireplug incident. 

Still another reason might he, "Weil, look 
how fast Russia and the L nited States are 
fortifying themselves." You are absoluteh 



correct; the old rat-race to arms has begini 
all over again. The goxernnient is following, 
yet promoting, the ever-increasing cry of the 
public, "Arm for war with Russia." 

What is the gist of this rumored Russian- 
United States conflict? Russia and the United 
States are simply two countries with two 

ideals communism and capitalism. Just as 

there are bound to be differences between 
members of the same family, so there are 
going to be conflicting interests in the embry- 
onic U.N.O. World peace cannot come over- 
night; it is a state that can be attained only 
through constant work and a growing luider- 
standing. 

Understanding between the nations of two 
peoples cannot be brought about by believing 
every wispy rumor, opinion, or bit of sensa- 
tionalism that comes down the gutter. L nder- 
standing comes through faith in one's fellow

Do you want to know where you come 
in here, Mister? Sure, \oii're just an engineer 
and you're entitled to feel that the business 
of diplomacy and war-waging should be left 
to your tax-supported government. BUT! 
Call it human psychology or what you will, 
it shouldn't be very hard for you to figvue 
out that, if for one week, commentators, news- 
papers, and magazine publications made no 
mention of the possibility of a war with Rus- 
sia, the odds are two to one that T. C. Mits 
(The Common Man In The Street) would 
forget even the existence of such a rumor. 

Mister, if you don't want to go back to 
war, there are two things you and all the rest 
of the engineers can do : ( 1 ) Try to have a 
little more faith in the human race by (2) 
not spreading every sad tiding of a foreign 
crisis that comes your way. If you and the 
rest of the American people help tight this 
sensationalism, the probabilitx of war will 
just die a natm-al death.

THE TECHNOGRAPH 




In safe hands . . . even at 60 below! 



Do YOU REMEMBER when winter meant storing the family 
car till spring? Not so many years ago, a car owner's fear 
of an ice-shattered motor was a dread reality ... if he didnt 
drain his radiator and store his car once cold weather hit! 

What was needed— acutely— was an automobile anti-freeze 
that would prove always dependable yet economical. One 
that would hold up under any operating temperature. That 
wouldn't foam and boil away. That would resist rust and 
corrosion to the nlh degree. 

That's where Union Carbide research entered the picture. 
The result? "Preslone" anti-freeze. Since then this product 
—the first all-winter anti-freeze— has assured millions upon 
millions of motorists of ever-improved driving performance, 



with assured safety . . . throughout the bitterest weather. 

This is but one example of the way the people of Union 
Carbide are helping to better our daily living. And UCC 
stands ready to help solve other problems . . . wherever 
better materials and processes are needed.

Experiment Station . . . 

( C'(iiitinuccl fidiii I'agc iS) 

Although the central office of the 
Station is located in Civil Eiigineeiiii}; 
Hall, the experimental wnik is carried 
on wherever equipmenr and facilities 
are available. 

Regular equipment of the I ni\ersit\ 
is used first for instruction puiposes. 
This equipment is generally a\ailable 
for experimental use when not being 
used for class and laboratory. Ho\\e\er, 
in many cases additional equipment is 
required for special projects. Where co- 
operation with industry is involved, some 
of the equipment and materials and 
other facilities are SLipplied by the coop- 
erating agency. For example, in car 
wheel tests, the manufactiu'ers supply 
the wheels ; in locomotive performance 
tests, the carriers come from rolling 
stock. 

It is sometimes appropriate antl e\en 
necessary to use eqiupment of other 
agencies of the State, facilities of Fed- 
eral Bureaus, and plants of private 
enterprise. The State Geological Survey 
anil the State Water Siu'vey are both 
located on the campus, making coopera- 
tion con\enient. federal Hiueaus include 
the L. S. Bureau of Mines and the 
Bureau of Standards. Railroad lines and 
steel mills are also used. 

From the beginning, it has been the 



policy of the Station to provide sub- 
stantial, high grade, thoroughly \inhiased 
information. 

The Station endea\ors to establish 
fundamental principles which can be 
applied to the solution of engineering 
pioblems, not primarih- to carr\' on com- 
mercial tests, and never to collect data 
for propaganda piu'poses. The results 
ha\e been reliable, trustwortin', and 
woithwhile contributions to the science 
of engineering. 

Each engineering department is con- 
ducting research in its various fields. 
These investigations may have had a 
particular appeal to staff members be- 
cau.se of their knowledge and interest 
in the particular subject. The work is 
stimulating to engineering instructors, 
and is generalh' valuable to the engi- 
neering profession and to industry. 
Many stLidies have had a large influ- 
ence on the development of engineering 
science and practice. 

Puhluatirins 

Accounts of inxestigations are pub- 
lished as soon as the information is avail- 
able so that, at the earliest possible date, 
those interested may benefit from the 
experiments and conclusions reached. 
One advantage of University investiga- 
tion is the freedom with which the Uni- 
\ersity can distribute unrestricted re- 
ports of findings. 

Most results are published in the form 



of bidletins, of which .5iS5 have been 
issued since the Station began. These 
bulletins contain the results of investi- 
gations by the Station .staff. Sixty circu- 
lars and 45 reprints have also been pub- 
lished. Circulars present information of 
impoitance compiled in part from Sta- 
tion studies and in part from outside 
sources. Reprints make available to the 
Station's mailing list important articles 
by staff members which first appeared 
in Technical journals, proceedings, and 
transactions. 

Traininij of Men for Research 

An advantage of an experiment sta- 
tion at the University, rather than an 
independent research organization, is the 
training of men in the methods of scien- 
tific research. Thus, the University at- 
tracts many who desire to do graduate 
study and prepare for scientific work. 

The University maintains re.search 
graduate assistantships in the Engineer- 
ing Experiment Station. Other assistant- 
ships are maintained by industrial or- 
ganizations. The assistantships are avail- 
able to graduates of approved technical 
schools and universities who are prepared 
to take graduate study in engineering, 
physics, or applied chemistry. No more 
than half of the time of these assistants, 
during 10 months of the year, is re- 
quired in connection with the work of 
the department to which they are as-

from around the world. Electron mi- 
croscopes peer deep into the world of 
the infinitesimal. 

These, and other "leaves" on our new 
tree of knowledge are rooted in creative 
research — as carried out at RCA Labora- 
tories in Princeton, N. J. Here, scientists 
seek new scientific principles, improve 
old ones, put them to new uses. 

Already on their achievement list are hun- 
dreds of basic developments in electronics, 
television, radio, electron tubes, radar, and 
recorded music. RCA research works con- 
tinually to give you better products.

Cooperation between the Engineering 
Experiment Station and individuals, 
firms, corporations, or associations in the 
conduct of engineering research brings 
up investigation of large and important 
problems. In many cases these involve 
expenditures much too large for the Uni- 
versity to provide. 

One project is to determine tlie oper- 
ating characteristics of the radiant base- 
board type of heating. Another concerns 
heating of a prefabricated basementless 
house. In the mechanical engineering lab- 
oratory a project is to determine the bal- 
ance of a forced warm air heating sys- 
tem when the total quantity of air flow- 
ing is reduced. 

The Department of Theoretical and 
Applied Mechanics is making a study of 
cable sheathing. A cooperative project 
between Civil Engineering and TAM 
is a study of highway bridges. A great 
deal of work is being done on railroad 
rails and joint bars. 

The Station is investigating improved 



methods of highway and airport drain- 
age, including some that will apply par- 
ticularly to high-speed superhighways. 
Station engineers are studying storm 
outlets, gutter forms, and the design of 
collecting systems and trunk .sewers. 

The research being carried on in the 
Department of Electrical Engineering 
concerns stLidies of electron tubes, radio 
direction finding systems, antenna char- 
acteristics, and electrical measurements, 
supersonics and infra-red investigations, 
and a survey of electrical insulation 
practice. In conjunction with the Physics 
and Ceramics departments, solid state 
studies are being made. 

A project of vital concern to thou- 
sands is the study of the production of 
drinking water by the use of diatomite 
filters. 

A stud\' of the cooling power of 
quenching media for steel and recrystal- 
lization studies are being made in metal- 
lurgical research. 

In aviation research, a project is the 
development of theory for analyzing and 
designing supersom'c propellors. As air- 
plane flight speeds approach the speed 
of sound, a portion of the propellor 
blade must operate above the speed of 
soimd. This produces shock waves and 
a consequent reduction in the efficiencN' 
of conventional propellors. 

The Department of Ceramic Engi- 



neering is progressing in the develop- 
ment of a porcelain vacuum tube for the 
betatron and development of special 
ceramic coatings for aircraft exhausts. 
Refractories for smelting low-tempera- 
ture enamels, and standard tests and 
evaluations of kitchen wares are being 
studied. 

These gi\e a brief view of the wide 
\ariety of the approximateh' 60 proj- 
ects now in progress. Through coopera- 
tion and support of various agencies and 
Illinois citizens, the Engineering Experi- 
ment Station is helping to improve a 
multitude of materials, products, and 
processes, and in this way it is benefiting 
all our citizens.

EXCITING NEWS ABOUT 

Du Font's Newest Fiber 

Hundreds of smaller businesses will join with Du Pont 
in bringing benefits of Orion''' acrylic fiber to you 



Strong sunlight will damage most 
fibers — but not "Orion" acrylic fiber, 
the latest synthetic yarn to come 
from the Du Pont laboratories. This 
remarkable fiber, which took eight 
yeairs of intensive research to de- 
velop, has a lasting resistance to sun- 
fight, mildew, high temperatures and 
even sulfuric acid. Experts say that 
it is the best fiber yet found for out- 
door use. 

In 1940, Du Pont scientists began 
work on a new fiber that seemed to 



have unusual properties. Develop- 
ment continued during the war when, 
under the name "Fiber A," the out- 
put went for military use in the hot, 
humid South Pacific. Recently the 
Du Pont Company decided to build 
a plant at Camden, South Carofina, 
for full-scale production. This new 
plant will cost about twenty-two 
million dollars. 

While samples of "Orion" fiber are 
now in the hands of knitters, weavers 
and finishers for experimental pur-

poses, it will probably be late 1950 
before articles made of it will be gen- 
erally available. Then you can expect 
to see it in awnings, convertible auto- 
mobile tops, golf bags, sails, electrical 
insulation, as well as certain articles 
of clothing. 

In developing the uses of "Orion," 
Du Pont will work with hundreds 
of smaller businesses — a "partner- 
ship" that will bring Americans not 
only new and better products, but 
more jobs, more business activity and 
another contribution to better Living.

picture story of one company's 
contributions to America. For 
your free copy, write to the 
Du Pont Company, 2503 Ne- 
mours Building, Wilmington, 
Delaware. 




OUTDOOR uses of "Orion" will include furniture fabric, golf bags, sweaters and swimming suits. 
New fiber stands up extremely well under sun and rain.

tormerly called cheatiiiK is also very 
helpful. This usage is merely the smug- 
gling of useful bits of information into 
an examination. This is accomplished in 
a multitude of ingenious ways and some 
of the best minds on campus are invent- 
ing i\ew and more foolproof methods at 
this very time. 

Probably one of the best and most 
seemingly apparent methods is the writ- 
ing of pertinent formulas on your slide- 
rule with black India ink. If done care- 
fully it blends with the rest of the gib- 
berish on the calculating timber and will 
pass unnoticed. If, however, an emer- 
gency arises the evidence may be suffi- 
ciently obliterated wirii a ipiick swipe of 
a sweaty palm. 

Another method which I learneil 
straight from an instructor is the use of 
the fingernails as a place to copy infor- 
mation. They are easily hidden and rlie 
e\idence is also easily removed in a 
pinch. 

()ther parts of the anatomy are simi- 
huly incorporated. An engineer of the 
opposite sex was showing me some of her 
more easily revealed finagle factors but 
when I suggested a more thorough 
search she politely refused. As you can 
see, research on this subject can be ex- 
tremely interesting. 



But now let's turn to a use of our 
faithful finagle factor, or adjustment 
coefficient, as it is sometimes lo\ingly 
called, that is not directly connected to 
a numerical or formula answer. I can 
best explain by using an illustration 
gleaned from the experiences enjoyed 
(luring those golden da\s at the (lales- 
burg Division. 

It was always best to be comparati\ el\ 
busy while in chem lab. That ma\ f.r/iiii(l 
eas.\, but is far from it when the experi- 
ments have all been dry-labbed previ- 
ously. This particular fellow escaped the 
issue successfully b\ always starting 
some water to boil at the beginning of 
the period. 

If the instructor came around .ind 
asked him what he was doing he could 
alwa\s answer truthfully, "I'm boiling 
water." This would satisfy the old 
snoop and he would charge off to find 
someone (an extremeU simple task, in 
keeping with his mentality) who didn't 
know what, if anything, he was doing. 

Reflect on your own labs and I'm 
sure you'll think of many ways in which 
this method will apply and be very use- 
ful. Remember that it is the obvious 
that is overlooked. 

No, the finagle factor is not some- 
thing that you can work out on the in- 
verted P or frustrated Z scales. It is an 
extremeh \ariable variable and since it 
has such a wide range of applications it

In connection with this he has already 
helped design an oscillator for the cyclo- 
tron. 

Professor (herald F. Tape, born in 
Ann Arbor, Michigan, received his R.S. 
degree from Michigan State Normal at 
Ypsilanti in 1933. It was there that he 
decided between mathematics, chemis- 
try, or physics for his chosen career. As 
a junior, he taught a freshman lab sec- 
tion in physics. 

After receiving his M.S. at the L iii- 
versity of Michigan, in 1936, he con- 
tinued there to get his Ph.D. in 1940. 

In 1939, Tape was at Cornell in- 
structing a physics cyclotron group on 
nuclear physics. The year 1942 took 
him to the M.I.T. radiation lab to 
work on micro-wave radar. Here he 
completed four projects; helping to de- 
velop an airborne radar system; research 
on a radar relay system (the basis for 
the T. V. relay stations) ; work on de- 
vices for training radar men ; and work 
in field service developing uses for radar. 
In 1946, Mr. Tape became an assist- 
ant professor in physics at the Univer- 
sity of Illinois. In 1949 he was awarded 
an associate professorship. 

Besides his contributions on the cyclo- 
tron, he finds time to belong to several 
honoraries: Sigma Xi (research). Phi 
Beta Kappa, Phi Kappa Phi ( Engineer- 
ing), Kappa Delta Pi (Education). 
He also has written several articles (a 
recent one in The Physical Ri'vinc. is 
entitled "Radar Relay") and is cur- 
rently serving on the following commit- 
tees in the Engineering College: policy 
and development committee, committee 
on review of student records, and the 
committee on review of freshman cur- 
riculum, of which he is chairman.

PROBLEM — Every so often, as the commutator segments 
of large motors wear down, the mica between them must 
be cut down. Your problem is to work out a tool which 
permits the undercutting to be done without removing the 
armatures from the motors. 

THE SIMPLE ANSWER— An S.S.White power drive fJexi- 
ble shaft hooked up to an electric motor gives you the basis 
of a portable power unit for driving small rotary saws. A 
handpiece designed for mounting the saws finishes the tool. 
The illustration below shows such a unit made by the Martin- 
dale Electric Co., of Cleveland, Ohio. 

The time and labor-saving advantages of having an 
easily manipulated power tool which can be brought to 
the work, can be readily appreciated. S.S.White flexible

head of the IX-p.-irtment of Theoretical 
,ind Applied Mechanics here. 'Jhe pre- 
sentation was made at the a n n u a 1 
ASME banquet held at the Statler 
hotel in New York City. 

The award, which was endowed in 
1020 in the will of W. R. Warner, 
widely known mechanical engineer and 
-ASME member for 49 years, is gi\en 
for an outstanding contribution to per- 
manent engineering literature. 

Profe.s.sor Seely has been a staff mem- 
ber here since 1909 and has been head 
of his department since 1934. In addi- 
tion to teaching, he has conducted ic- 
search in the properties of materials and 
in hydraulics; be has written numerous 
articles and three books. 

The books he has authored are: And- 
lytical IMech/iniis for Engineers (co- 
author with N. E. Ensign), 1021 ; Re- 
sistanec of Mntcrinh. 1025; and Ad- 
vance Meehanirs of Mater'uds, 1032. 
Thes? books, the society said, "by their 
completeness, clarity of presentation, and 
extensive use have helped to set a pat- 
tern of thought and teaching in the 
fields of mechanics and strength of 
ni.'iterials." 

After his graduation from Worcester 
Polytechnic Institute, Prof. Seely spent 
two years working in industry. He then 
came to the University as an instructor 



and was appointed a full professor in 
1021. 

Over and above his man\ duties in 
the University, Prof. Seely has served 
as an Alderman in the Urbana City 
Council, as vice president of the Savings 
and Loan Association, and as vice presi- 
dent of the local council of the Boy 
Scouts. He also holds membership in 
\arious honorary scholastic societies in- 
cluding Tau Beta Pi, Sigma Xi, and 
Phi Kappa Phi. He is a member of the 
Champaign-Urbana Kiwanis Club and 
of the Engineers Club of Chicago. 

Hats off to Prof Seely from the 
Illinois engineers!

How to help a coal loader 
throw its weight around! 

The constant pushing, swinging, scooping action 
of a mechanical coal loader places heavy shock 
loads on the bearings. To carry these tough loads, 
engineers for leading mining equipment manufac- 
turers specify Timken- tapered roller bearings. 



Why TIMKEN' bearings can 
take the tough loads 

Due to their tapered design, Timken bearings take 
radial and thrust loads in any combination. Made of 
Timken fine alloy steel, rolls and races are case- 
carburized to give a hard, wear-resistant surface 
with a tough inner core to withstand shock. Because 
the load is carried on a line of contact between rolls 
and races, instead of being concentrated at a single 
point, stress is minimized.

cig.ir-shaped aliunimun fixture, with its 
two eight-foot fluoresci-nt lam|is, was 
the result of the quest. 

And it seems to be the answer, for it 
should be far less glaring than other 
street lights, with particularly good visi- 
bility on wet and icy pavements. Pedes- 
trians should welcome it, too, for its 
added convenience and protection. 

Although this new (i-E street light 
represents what has been called a "sig- 
nificant advance in the quest of more 
comfortable seeing," there are still some 
problems left to be solved — almost all 
of an economic nature. 

In that this new fi.xture is much 
larger than those of conventional design, 
initial cost, mounting, and maintenance 
may have a tendency to discourage its 
early use on a large scale. 



Thermoset Varnish— 
—Corrosion Inhibitor 

A new thermoset \arnish, iircjduced 
by Westinghouse, was intendeil origin- 
ally as an electrical insulation. Hut it 
has found many u.seful applications as 
physical insulation, particularly for pre- 
venting corrosion of steel exposed to salt 
air or water. 

It has been used as protective coating 
on powei-center control cabinets, push- 
button stations, ducts, and pipes that are 
subject to corrosive atmospheres or 
chemicals. 

To the list — which inckules a curious 
assortment of devices from torpedoes to 
automobile exhaust pipes — a new one is 
added: railroad spikes on electrified rail- 
ways.

How America's ^'Underground'' works for you 




THERE areenoughmilesof oil and nat- 
ural gas pipe lines in the U. S. A. to 
circle the world at the equator 16 times! 

This vast, 402,000-mile network is 
made up of crude oil lines, oil products 
pipe lines and natural gas lines. This 
network has helped to make the benefits 
of gasoline, fuel oil and oil products 
readily available to ever\'body ... it has 
helped to bring gas heating to many 
parts of the countrj'. 

But this constantly-expanding under- 



ground network is far from complete. 
It will require thousands more miles of 
pipe in the near future. To help meet 
this demand. United States Steel will 
put two more large-diameter pipe mills 
into operation in the next few months. 

The steel industry is a growing indus- 
try, not only in terms of physical plants 
and facilities, but in terms of personnel, 
too. At the present time, the number of 
United States Steel employees partici- 
pating in educational programs is ex- 



ceeded in size only by the student bodies 
of a few of our largest universities. 

The fundamental objectives of these 
programs are to assure employees maxi- 
mum opportunity for personal develop- 
ment and to provide them with a sound 
foundation for advancement within the 
organization. 

The training programs in United 
States Steel have become the "pipe line" 
to successful careers for hundreds of 
capable young men.

Glass that picks fire out of a light beam 



The electric lamps you see between the boxes 
on the table are exactly alike — they generate 
both powerful light and intense heat. 

Ifyou should concentrate the beam of one 
of them with a reflector and plug it into an 
ordinary socket, you'd be practically blinded 
by its glare and your clothes scorched by 
the heat — unless you turned away fast ! 

But look what happens when you put them 
into the fixtures in the foreground, so their 
beams are covered by two different kinds of 
Coming glass. 

The beam from the bulb on the left is 
cooled down so sharply that you can hold a 
wisp of newspaper in it for hours without 
its catching fire. Yet the light is almost as 
dazzling as ever. 

Notice now that no light apparently shines 
from the bulb in the fixture on the right. But 
if you hold a piece of newspaper over it — 



in a matter of seconds you have fire in your 

hands! 

The explanation is : One of the glass plates 

transmits the comparatively cool, visible rays 

generated by the bulb, blocking off most of 

the invisible heat rays. The other allows only 

the invisible heat rays to pass. 

These pieces of glass are only two of the 
dozens of ray-transmitting or ray-blocking 
glasses that Corning makes — glasses that 
can pick out any segment of the light spec- 
trum and put it where it's needed. 

For example, a lamp shielded with a Com- 
ing glass which transmits only near ultravio- 
let rays lights automobile instrument panels 
without glare. Another kind of Corning glass 
transmits only invisible infrared rays and 
is used in electronically controlled burglar 
alarm systems. 

Throughout industry, Corning means re- 



search inglass — and these ray-blocking, ray- 
transmitting glasses represent only one of a 
multitude of outstanding developments that 
have earned Coming this reputation. 

We hope you'll keep in mind that Coming 
research and technical skill have made glass 
one of the most versatile engineering mate- 
rials there is. 

For when you're out of school and are 
concerned with product and process plan- 
ning, you'll find it to your advantage to call 
on Coming before your plans reach the blue- 
print stage. Corning Glass Works, Corning, 
New York.

Banox— Rust Inhibitor 

A new salt pnxlutt w liich will rend ti) 
pre\eiit rustinj; ot car tcmleis and un- 
ilfrbodies when used to de-ice streets 
and highwavs has been announced by 
officials of the Carey Salt Co. 

Included in its manufacture is a rust- 
inhibitinij chemical, "Banox," a product 
(if Calf^on, Inc., vv'hich forms a colorless, 
in\isible, yet protective film on metal 
surfaces when street slush is splashed 
aj;ainst fenders and auto underbodies. 

Salt is widely used by American cities 
for clearing streets for traffic and pedes- 
trians because it promotes rapid melting 
of snow and ice, does not clog gutters 
or storm sew-ers, and is easy and econ- 
omical to use. Carey officials announced 
the production of this product which 
may be used when municipal engineers, 
service directors, truck, and bus fleet 
operators, and motorists fear the corro- 
si\e effects of the brine that results 
when salt is combined with melting snow 
or ice. 

Twin-Bonanza 

The new Beechcraft Twin-Bonanza, 
Model 50, is a completely new post-war 
design of an all metal, six-place, medium 
priced, twin-engine airplane. Built into 
tile Twin-Bonanza are all of the flight 



ad\antages of the smaller single-engine 
Beechcraft Bonanza and the large twin- 
engine Beechcraft Model 18 seven-to- 
mrie place Executive Transport, accord- 
ing to Walter H. Beech, president of 
Beech Aircraft Corporation. 

This first Model 50 is powered b\ 
two 2b()-hf> Lycoming engines. With a 
cruising speed estimated at over ISl) 
////>/; and a range of about 1000 miles. 
the manufacturer stated the Twin-Bon- 
anza will have a good single-engine ceil- 
ing under full gross weight conditions. 

Designed primarily as a super room\ 
five-place airplane, this newest Beech- 
craft can legally accomodate six people 
for shorter ranges. The manufacturer's 
present estimates indicate the price of 
this new Beechcraft will be approxi- 
mately ,^30,00(1. 

Pro|ection Welder 

A riiiinipson projection welder, with 
Westmghouse three-phase, low-frequen- 
cy converter, is being used by the Com- 
mercial Filters Corporation of Boston, 
manufacturers of Fulflo filters. 

The welding control contains six igni- 
tron rectifiers that convert the three- 
phase, 60-cycle input into a single-phase 
12-cycle output. Its principal advant- 
ages are distribution of the power re- 




quirements among three phases (there- 
by reducing the peak demand), and high 
power factor (about SO per cent). Fur- 
thermore, an improvement in the prod- 
uct is gained because of the slower rate 
of rise of the low-frequenc\ welding 
current. 




Newest look in the Beechcraft series is seen in this sleek Twin-Bonanza, 
Model 50, designed for a cross-country ranging of 1000 miles. (Photo

Flame-Seal 

Even the hot scorching flame of a 
blow torch cannot ignite a sheet of 
inflammable newsprint if it has been 
coated with a new fire retardant and 
non-toxic paint now being introduced 
for the first time in Illinois and Indiana. 

The Flame - Seal Corporation an- 
nounces the availability of the new 
paint which "at no time «'ill support 
combustion." 

The new fire retardant coating has 
already been approved and listed by 
L nderwriters' Laboratories, Inc. 

When typical fast-burning lumber or 
highly combustible partition board is 
coated with Flame-Seal, the protected 
surface can withstand the direct attack 
of an intense flame for hours without 
igniting or showing any sign of flame 
spread. 

When the new paint fights fire it 
undergoes a complete physical transfor- 
mation and forms a crust-like fire-re- 
tardant wall at least eight times the 
thickness of the original coating. 

Flame-Seal is unique because it gives 
off no toxic gases while being applied 
or when exposed to fire. 

The new fire retardant coating comes 
ready to use, requires no mixing of 
special chemicals, and can be applied 
directly from its original container by 
brush or pressure spray gun. Not af- 
fected by humidity, it may be applied 
during any weather conditions and dur- 
ing any season of the year.

Rddtir Traffic (Wtp 
\ In- Illinois Division of Highways 
has loaned the I'niversity traffic engi- 
neers at) Electro-Matic Speed Meter for 
traffic speed studies. Recordings are be- 
ing made of the average speeds of autos 
on Springfield, Prospect, Green and 
other main traveled streets in Cham- 
paign and L rbana. 

This bane to speedsters is a very accu- 
rate radar device that can measure a 
car's speed to within 2 ntph within a 
range of 150 feet. It consists essentialh 
of three parts: antenna unit, indicator 
unit, power unit. The antenna unit is 
beamed at oncoming or receding traffic 
and ma\ be set up near the roadway or 
in a parked car. The indicator unit and 
the power unit may be placed where\er 
convenient. 

It may be operated from a 6-\'olt auto- 
mobile battery or from a 120 volt 50-60 
cycle AC supply (50 watt rating). 



A graphic recorder may be connected 
with the speed meter if a permanent 
record of speed readings is desired. 

It is not known whether or not this 
$900 radar cop will be given regular 
duty on Illinois highways but some of 
the other states are finding it very effec- 
tive. According to C. C. Wiley, profes- 
sor of highway engineering, this instru- 
ment is being used in this area merely to 
determine the actual speed situation and 
not to apprehend speedsters at the pres- 



" Airmen of I ision" 

Alartin Warko and Bob Johnson, 
aeronautical engineers, pooled their de- 
signing talents and received second prize 
in a recent Air Trails' airplane design 
contest. 

Their creation, a flying wing attack 
fighter, is powered by two turbojet en- 
gines of 5,000 lbs thrust each, has a 



wingspan of 50 feet and can carry 3,000 
Ihs of bombs. It is designed for a speed 

of 650 mph. 





As displayed here with the modern aluminum case in which it travels, 
the Electro-Matic Speed Meter will be one of the many I SEE exhibits 
next March 10-11.

An encouraging note comes from a 
survey made by Harvey H. Jordan, as- 
sociate dean of engineering. His survey 
shows that of the 1,179 engineers who 
graduated in 1949, only 3.1 per cent are 
still unemployed. 

Of the 962 engineers who got R.S. 
degrees, 122 are continuing their studies 
as master degree candidates in the grad- 
uate colleges. A few of the graduates 
who are employed are doing work which 
isn't exactly engineering and are seeking 
re-employment in fields more suited to 
their training. 

The survey also indicated that there 
are not too many graduates in any of 
the divisions of engineering.

By Hvnry Kahn. I'h.E. 'HO anil Mtan Kvi'liu €'h.ii. '."iO 



Cr/fiss is such a coniinun iiititerial that ii'e seldom a/>/>r(iifi/r its I'tiried proper- 
lies. Xot only is it useful in everydeiy applications, hut it is also an important 
engineering material. 

This nrtielc presents sonu of the hnekground of the i/luss hloiving ernft 
and tells of the important jobs <lont hy i/lass hloiccrs on eiii/ipus. 



There are tnur labs on campus that 
are probably the least known but yet 
among the most important places at the 
University. (One of the labs is in Xoyes 
Laborator\' ; another in the Physics Lab- 
oratory; another in the old Electrical 
Engineering Building; and the fouth in 
the Betatron Building. They are the 
glass labs where technicians carry on a 
skill that goes back thousands of \ears. 

7 he Beginning of (iltiss 
The most common natural glass is 
obsidian which has a volcanic origin. It 
sometimes occurs as transparent blocks 
but it is usualh' black; specimens ha\e 
been found that were green, red, and 
brown. This glass has been traced back 
to the Bronze Age when it became an 
article of commerce. It remained as such 
for thousands of years. 

Just where and when glass manufac- 
ture started has remained a myster\' to 



this day. It is not difficult to imagine 
the glass-making obstacles encountered 
thousands of years ago. For one, a tre- 
mendous amount of heat is needed. 

The tools used by glass-blowers of oin- 
day are, in themselves, witnesses to the 
long history of glassblowing. Nothing 
the blower uses is complicated: a long, 
narrow, hollow tube, a flat board, a 
solid bar of metal several feet long, and 
variously shaped pinchers. These same 
tools have been used in making glass- 
ware since the first glass goblet was 
fashioned. 

The oldest known pure glass is a 
moulded amulet of deep lapis lazuli color 
which is thought to date back to 7000 
B.C. At that time and for many hun- 
dreds of years thereafter, glass trinkets 
were used for personal adornment. 

It is interesting to note that glass 
"jewels" were placed in a gold crown

of an Egyptian pharoah along with the 
usual cluster of gems. Egypt, as a matter 
of fact, was the chief headquarters of 
the glass makers for 1 ?00 years before

The first blowpipe is generally 
thought to have been made between 300 
and 20 B.C. by Phoenician glassworkers. 
That pipe was much the same as any 
used today: 4 to .^ feet long with a 
knob at one end and a mouthpiece at 
the other. 

The manufacture of window glass 
appears to be one of the last develop- 
ments in glass making. The first panes 
have been traced back to the Third 
Century which would put it o\er .i()(l 
\ears after the blow-pipe. 

Off-llnnd Class Blouing 
The term "off-hand" indicates that a 
glass piece is made without the use of 
molds. .Most of the good table-ware is 
made by this method. 

In order to m.ike a wine goblet, for 
instance, the blower first dips the knob 
end of the blow-pipe into the vat of 
molten glass and collects what is called 
a "gather." Then, by blowing through 
the pipe, he forms a bulb which is tear- 
drop in shape. By rotating the pipe and 
swinging it, he is able to get the desired 
thickness. 

Another blower has meanwhile col- 
lected another gather which remains as 
a molten mass and is not blown. The

Illinois Student 



TIME: March 10, 1950. 2:00-10:00 p. m. 

March 11, 1950. 9:00 a. m.-6:00 p. m. 

PLACE: University of Illinois, Champaign-Urbana, Illinois 

SETTING: Engineering campus 

SCENE: The big engineering parade has just finished. 
Still laughing about the humorous floats, people 
are pouring through the open doors of engi- 
neering buildings. 
Tin can motors, black light, jet engines, wind tunnel 
experiments, world's first betatron, induction hardening, 
Geiger counters, 3-million pounds stretching a thick steel 
plate till it snaps like a 
rubber band! 

This I SEE at the lllirois 
Student Engineering Exhibit. 
Complete displays are rep- 
resenting all fields of engi- 
neering, their industrial ap- 
plications, and their training 
facilities at the University of 
Illinois. 

I'm having loads of fun 
and a real opportunity to 
learn about this interesting 
engineering world. What's 
more, it's all free for the 
looking! 

In world-famous Talbot 
materials testing laboratory 
I SEE one of the world's 
most powerful testing ma- 
chines. It easily pulls apart 
steel members or exerts 3 
million pounds force com- 
pressing concrete columns 
until they explode and shat- 
ter. These demonstrations of 
brute force are really im- 
pressive. 

In the beautiful new 
Electrical Engineering Build- 
ing I SEE some thrilling elec- 
tronics and lighting exhibits. 
Words, phrases, and even 
my own name are written 
by electrons on the face of 
an oscilloscope by a ghost writer. A suspended tin can 
rotates dizzily, but without any visible mechanism. I'm 
told it is an exciting example of the action of three phase 
rotating fields. 

I SEE a display of weird and thrilling lamps used 
during the past half century. An important engineering 
application of polarized light demonstrates be ;utiful 
color lines that determine stresses in plastic models of 
gears and I-beams. I'm shown how gears lose their only 
set of teeth! 

I SEE a bright and shiny 1941 Oldsmobile chassis 
showing the relation between valve and spark timing. 
In addition, I SEE gasoline tested for octane rating and 
I'm told how compression ratio affects operation of auto- 




mobile engines. Gee, this new Mechanical Engineering 
Building is a beautiful and efficient place! 

The heat treatment lab is operating at full capacity 
to show me how induction, gas, and electric heating are 
used to make better products for everyday use. 

I SEE the Mechanical Engineering Laboratory where 
furnaces are tested; steam engines are operating, and 
air conditioning apparatus is being demonstrated. I sure 
didn't know that air could be dried by spraying water 
through it! I SEE the human environment lab where 
engineers study people as well as machines. 

In the Ceramics Building I learn all about the increas- 
ingly important ceramics industry. I SEE brick machines 
being used, and enameling operations that may mean 
better jet and rocket engines in the near future. 

The traffic engineers show me the latest in traffic 
cops— a radar speed meter. Just set it up on the corner, 
point it at an approaching cor, and read its speed on 
the meter! It does everything except catching the culprit 
and writing the ticket. I SEE how traffic counts of origin 
and destination are used for designing routes and inter- 
sections. 

I SEE a beautiful exhibit about architectural engi- 
neering. Models of buildings and landscapes and student 
designs demonstrate the important work of making 
structures efficient, lasting, and beautiful. 

The world's first betatron, invented and built by 
Professor D. W. Kerst of the Physics Department, is being 
demonstrated. That 2-million volt electron beam pocks 
plenty of atomic punch. But I'm told that a 300-million 
volt betatron is now being built on campus. 

And speaking of atomic psysics— I SEE Geiger count- 
ers detecting radioactivity all over the place. I'm lousing 
up the works, though, with a vial of radium in my hip 
pocket. 

I SEE agricultural engineers exhibiting a panorama 
of agricultural equipment; they show the difference

the volt, ohm and amp bugs .... 



between a farm that is planned and a farm that just 
happens. Rural electrification and soil conservation 
methods are explained. 

In the chemical engineering building I SEE how 
distillation towers function — how one compound goes 
up while another comes down. 

Metollurgical engineers prove to me that even the 
smoothest metal surfaces are composed of crystals. I SEE 
how invisible cracks inside a bar of metal can be dis- 
covered magnetically. I give one of the engineers my 
only bright shiny penny and he mounts it beautifully in 
lucite for me. 

After stepping into the foundry room, I SEE the big 
cupola pouring forth its mass of molten metal. I pick 
up a hot souvenir, flip it in the air till it cools off, then 
stuff it into the radium pocket to get "hot" again. 

Civil engineers present a display of old surveying 
equipment and models of various types of structures, 
construction jobs, equipment, and materials. Gee, it 
must be interesting work! 

A model shows how reservoirs get filled with silt 
because of density gradients. I SEE the right and wrong 
of plumbing installations and what happens when "live" 
sewage goes the wrong way. 

Mining engineers show me a complete process— 
from original ore extraction through purification meth- 
ods to the pure mineral. 

Aeronautical engineers don't "Blow the Man Down," 
but there is plenty of breeze in the wind tunnel. I SEE 
model airplanes being used for authentic experiments- 
determination of airfoil characteristics and other flying 
factors. In addition I SEE how jet engines get their 
thrust; a small ramjet and a demonstration model turbo- 
jet are operating. 

Freshman engineers have worked together to bring 
me an exhibit of General Engineering Drawing. It helps 
me to understand what the freshman year of engineer- 
ing must be like. 

I SEE all this and more. Lots morel It's all so fascinat- 
ing and I'm learning so much! 

I SEE crowds of people, all kinds of people— engi- 
neers, high school students, industrialists, students from 



other colleges, even economics professors. I'd like to 
know how many are here and what they all are. 

But I do know why they're here! Some have come 
to be entertained and are. Some have come to learn 
more about engineering endeavor, and they'll go home 
with a better understanding and appreciation. 

High school students came by bus-loads from all 
parts of the state. Some came in a group with physics 
and industrial arts instructors; some came individually 
and are staying overnight at the houses of buddies in 
school here. Most of this high school gang have come 
earnestly hoping to learn what engineering is; and each 
is comparing the various fields in an effort to determine 
his particular line of study and work. 

I couldn't help from laughing just a minute ago— 
a kid asked his science teacher how the dynajet engine 
worked. You should have seen the embarrassed prof 
refer the question to one of the aero engineering stu- 
dents at the exhibit! But that's his purpose: answer the 
queries of all who ask. 

After seeing the results of this engineering open 
house, I marvel at the work and enthusiasm of the engi- 
neering students at Illinois. There must have been coop- 
eration from all 3,500 engineers on the campus to work 
up a project like this. And with St. Pat's Ball as the 
climax, it must be quite an Engineers' Weekend. 

I'm certainly glad I come, for now I SEE.

Here at the L'niversit\ of Illinois tlie 
Engineering Experiment Station is cer- 
tainly iloing its part. Our highways, our 
homes, our automobiles, railroad cars. 
and planes, our college education — all 
have benefited from l'n!\ersity studies 
and itnestigations. 

Estahlishiiicnt of the Station 

The need for an experiment station in 
the College of Engineering was recog- 
nized long before its actual establish- 
ment 46 years ago. Investigation and 
studies of engineering, manufacturing, 
railways, mining, and other items of 
industrial interest were badly needed. 

Such a station could also improve 
teaching processes and develop new ma- 
terial for classroom and laboratory. This 
would help to keep the University work 
in step with progress in engineering and 
industry. It could also provide a means 
for educating and training graduate stu- 
dents in methods of conducting research. 

Much of the credit for the conception 
of the idea and the establishment of the 
station belongs to Professor L. P. Breck- 
inridge, at that time the head of the 
Department of Mechanical Engineering. 
For several years he had been making

He recently attended the

this honor through his

an effort to secure federal action to 
establish engineering experiment stations 
similar to the agricultural experiment 
stations already in existence. Failing in 
this, he proposed that the University 
establish an Engineering Experiment 
Station with State funds. 

In December, 1902, the Board of 
Trustees of the University of Illinois 
included in their list for legislative ap- 
proval a separate bill requesting funds 
to expand the activities of the College 
of Engineering. Faculty, alumni, and 
manufacturing and construction inter- 
ests joined in the support of the bill. 

In Alay of the following year, the 
(jeneral Assembly passed a general bill 
providing $1 S(),000 for the College of 
Engineering. Of the total, ¥;4.i,00() was 
allotted for the purchase of land and

the erection of two buildings, the me-

rlic iiurchase of additional equipment; 
and the remaining $77,000 was set aside 
to purcha.se apparatus to be used for 
engineering research to be carried out 
by the regular departments. 

Thus, by an act of the Board of 
I'lustees of the University of Illinois, 
the Engineering Experiment Station 
c.ime into existence on December 8, 
1')(13. This station was the first of its 
kind to be established in an educational 
institution in the United States and has 
served as a pattern for many similar sta- 
tions.

Before any attempt is made to deter- 
mine the time required in engineering 
school, it wouKi be well to investigate 
the things that must be accomplished b\ 
the student in that time. An evaluation 
of engineering education as a whole will 
point out those minimum educational at- 
tainments which the candidate for the 
U.S. degree in engineering must have 
mastered before he is prepared for grad- 
uation. 

An engineer is a human being and a 
citizen before he is an engineer. As such, 
there are certain fundamental studies 
which he must master. 

(^f these studies, the one that fills the 
most basic need is the study of commu- 
nications. The engineer, as well as the 
rest of men, must be proficient at read- 
ing, speaking, writing, and equally im- 
portant, listening. This is true not onh' 
j for his own progress and well being, but 
for that of his fellow men, country, and 
world. Before any problem, within or 
without engineering, can be solved or 
even grasped, it must be put into some 
mutually understood language. For the 
above reasons then, it is necessary that 
the student be thoroughly trained in the 
transmission and reception of written 
and verbal information. 



It has been the custom for the 
TECH to publish the first-place 
essay of the Tau Beta Pi pledge 
competition. Writing a nontechni- 
cal, etlitorial-type paper is one of 
the initiation requirements of this 
all-engineering honorary. 

Vinee McDonald's winning essay 
asks a question of considerable 
engineering interest, but it makes 
no attempt at a specific answer. 
Instead, a general explanation of 
the important factors of engineer- 
ing education is presented. Need 
of four or more years is depend- 
ent not only on the school but on 
the man. 



One section of his education should 
impart a woiking knowledge of things 
historical. Not only national and world 
history, but also the historical landmarks 
of philosophy, literature, music, and art 
should be known and appreciated. 

Although clear logical thinking is de-

sired for everyone, it is essential in engi- 
neering. The engineer must be able to 
think, and he must be trained to think 
efficiently. Undoubtedly, this is the most 
important phase of his technical training. 
The successful analysis and evaluation 
of data cannot be handled by many for- 
nudae and a group of pre-set circum- 
stances; they depend on agility, flexibil- 
ity, and logic in thinking processes. 

For an aid to thinking the engineer 
must be equipped with a sufficient 
background in mathematics. Mathemat- 
ics will not only reduce the labor of his 
thinking, but it will provide an acces- 
sory to thinking, and by means of its 
symbolism, open a new language more 
precise, clearer, and more logical than 
English. 

Further, the engineer must be trained 
efficiently to gather and record data. 
He must ha\e a thorough grounding in 
the fundamentals of all engineering with 
,111 emphasis on his selected field, finally, 
he must have a real and deep interest in 
engineering. 

Thus, the important qu.'ilifications 
have been listed. The more thoroughh 
these qualifications are filled the better, 
but some degree of mastcr\ of them is 
essential before the student is ready for 
his degree. 

So, then, to the question, "Should 
engineering be a five year curriculum?" 
we must answer, "Yes, if it takes that 
long — longer if necessary!" 

However, the student entering an 
engineering school as a freshman shouhl 
already have much of the ground wcuk. 
Actually, education, or engineering edu- 
cation in this case, is started at home, 
begins to be formally directed in grade 
school, and expands in high school. 

Thus, it could be said that "engineer- 



ing school" also encompasses the previ- 
ous twelve years of more or less formal 
education. Certainly, it may be said that 
"engineering tr.-iining" d o e s include 
them. 

If the grade and high schools effici- 
ently perform their work, the task 
awaiting the college is mereh' a further 
enlargement of previous work, and the 
necessary and desired status could be 
attained in a relatively short period of 
time. But, if previous schooling has been 
weak, or has failed almost completeU, 
the college must then fill in the voids 
to bring the student u|i to the desired 
level. 

The methods and the precise number 
of hours this process will require must 
be determined b\- the properly trained 
educators. As has been indicated, this 
time will decrease as the effectiveness of 
earlier education increases. Howexer, 
the previously mentioned minimum 
standards must be met, regardless of 
the time involved, if the graduate is to 
be considered an engineer in the full 
sense of the word. 



X-Ray Microscope 

An X-ray microscope, which makes 
visible the internal details of materials 
through which light cannot pass, has 
been developed by the (leneral Electric 
ComiKiny. 

Future refinements of the X-ray mic- 
roscope, which is at present in the lab- 
oratory stage of development, may re- 
sult in much sharper images and higher 
magnifications than are possible using 
visible light. 

Electron microscoiies are the most 
powerful magnifiers in use at the pres- 
ent time. They use a beam of electrons 
rather than light to form an image of 
materials under study. 

The X-ray microscope does not re- 
quire that samples under stud\ be in a 
high vacuum, as does the electron micro- 
scope. Because of this advantage, "it 
ma\ 'be possible to examine living mater- 
ials at much higher magnifications than 
ever before." 

Clear, sharp X-ray images, magnified 
10 times have been produced in the lab- 
oratory, and these images have been 
magnified 10 times further by photo- 
graphic enlargement without serious loss 
of detail.

Dan Keete and Carl Jacobs of the 
physical iniprovenient coiiimittee have 
already chalked up accomplishments. 
There were no bicycle parkinj; racks 
near the new M.E.H. Hikes aiul motor- 
cycles were being leaned into and over 
the struggling young hedges. A word 
from the boys and a result — temporar\- 
bike stands that will suffice till funds are 
a\ailable for permanent installations. 

Keefe and Jacobs are also plainiing to 
pro\ide some suggestion boxes around 
north campus. They would provide a 
direct means of communication with the 
Council. 

Kl) Note: Until tlmi yon oin hriny 
your ffripes to the 'J'k liiioi/rtil-li office. 
11 ere used to it! 

The Engineering Council is going all- 
out for an instruction improvement and 
faculty rating program. A thorough 
study is being made and all possibilities 
will be considered before any action is 
taken. The Council fully realizes the 
severe results of a poor rating program. 
Working on this committee are Vince 
McDonald, Jim Bienias, Jim (iarman, 
Dick Myers, and Don Savage. 

Council definitely plans to present an- 
other Engineering Convention this 
spring. Dick Myers and Wolfgang 
Junkel, co-chairmen, promise to make it 
a bigger success than the starter last 
year. 

What is possibly this year's most am- 
bitious project, I SEE, is taking definite 
form. The last engineering open house 
was held nine years ago, so only a few 
long-lived engineers know the back- 
ground of such an event. Up till that 
time, the traditional engineering show 
supplied considerable enthusiasm and 
spirit to the weekend. Now, however, 
the enthusiasm for preliminary work 
must be .self-excited to insure success. 

Besides the chairmen for each society 
(listed in the December Tech), there is 
an ambitious gang working on the cen- 
tral committees. The following are ef- 
fecti\ely planning solutions for general 
problems: program. Art Dreshfield; 
physical arrangements, Maurice Cobb ; 
promotion, Tom Brown; and parade, 
Connie Miiinich. 

Hob Wiley, an M.E. and former 
member of the Council, has been ap- 



pointed chairman for St. Pat's Hall. lli> 
committee is going strong making plans 
for this climax of the great engineering 
weekend. Connie Minnich is pushing 
publicit\ ; Al Makulec, tickets; Dick 
Swanborg, decorations; Jack Huiidles- 
ton, bids; and Ronald Hoefle, physical 
arrangements. 

]?y popular demand, Dick Cisne, the 
St. Pat's Ball dance master of the past 
two years, will once again ring out with 
"St. Patrick Was an Engineer." 

The time: Saturdav exening, March 
11. 

The place: Huff gym. 

SYNTON 

The December 8 meeting of Synton, 
also known as the Ham Club, featured 
an interesting discussion by Allen Wil- 
son, of the University's electron tube re- 
search lab. He showed some experimen- 
tal tubes and described the method of 
design and construction. 

The code practice machines ha\-e been 
set up in a new location, 41 E.E.B. 
Code practice sessions are still held on 
Tuesdays and Thursdays, and the ma- 
chines are seeing a lot of use. 

A. S. C. E. 

The best laid plans of mice and men 
often go astra\- (translated from the 
Scottish ) . This wise statement was 
clearly brought out at the December 6 
joint dinner meeting of the central Illi- 
nois section and the University student 
branch of the American Society of Civil 
Euguieers. 

The speaker for the e\ening was A. 
P. Geuss, chief design engineer for the 
Harza Electric Company. He was to 
speak on the "Petenwell Hydroelectric 
Project." However, shortly after begin- 
ning his talk he was taken ill. Fortu- 
nately, E. Montsford Fucik, consultant 
for the same company, was present and 
able to take over in place of Cieuss. 

Continuing on the same subject, 
Fucik, who was here for the Career 
Conference, made use of slide illustra- 
tions of the technical aspects of the 
$9,400,000 private undertaking. 

"The Wisconsin river, on which the 
Petenwell dam is located," he said, "is 
about the hardest working river in the 
country." Petenwell is located north of 
Wisconsin Dells and should be com- 
pleted very soon. 



PI TAU SI(]MA 

Formal initiation of pledges to Pi Tau 
Sigma, honorary mechanical engineering 
fraternity, took place in the University 
YMCA on the evening of December 8, 
194*^'. Fifty-eight pledges and three 
honorarv members were initiated at that 
time. 

Following tlie cereiiujiiy the uufiation 
banquet \xas held in Latzer Hall with 
Jerome Jacobson presiding as toastmas- 
ter and Dr. R. I. Mehr of the College 
of Commerce as the guest speaker. Dr. 
Mehr spoke on "Economic Illiteracy." 

Professor J. C. ]VIiles, faculty adviser, 
presented the retiring officers with keys, 
tokens of "jobs well done." After this 
an election of officers for the spring se- 
mester was held. The following men 
were elected to various positions : 

President — George Johns 

Vice president — William Eiszner 

Corresponding secretary — Wolfgang 
Junkel 

Recording secretary — Richard Jeffer- 
son 

No election was held for the office of 
Treasurer, held by Joe Ream. 

KERAMOS 

Formal initiation to Keramos, honor- 
ary and professional fraternity for cer- 
amic engineering, was held on the eve- 
ning of December 19 in the faculty 
lounge, mini Union. 

The new initiates, all of whom are 
outstanding stLidents in ceramic engi- 
neering, are Maynard P. Baideke, Don- 
ald Houltbee, Dudley Johnson, Robert 
Rosendale, Er\in Schuetze, and Stephen 
Stoddard. 

A. F. S. 

The American Foundrymen's Society 
spent the evening of December 1 profit- 
ably touring the General Motors foun- 
dry in Danville, Illinois. A welcoming 
reception was given to the group by Mr. 
Braun, plant manager, and his adminis- 
trative staff, who acted as guides during 
the trip through the plant. 

After going through the testing and 
control laboratory, where various testing 
machines and supplementary apparatus 
were shown, the group went into the

So complex are present scientific 
studies — such as in atomic research 
—that working out the "arithmetic" 
could take all of our scientists' time. 

Short cut through this drudgery is 
found in huge electronic computers, able 
to add or multiply numbers as large as a 
thousand billion in millionths of a second. 
But such speed is valueless unless— with 
comparable speed — the results of count- 
less computations can be kept "on file" 
and taken out again. 

Such a "file" now exists in a "memory" 
tube, developed at RCA Laboratories. It re- 
tains figures fed into calculating machines, 
stores them, memorizes new ones — speeds 
solutions through mazes of mathematics. 



Uses of RCA's "memory" tube are many. 
It will help atomic scientists acquire new 
knowledge . . . pro\'ide new information 
on supersonic flight . . . even help make 
rapid weather predictions! It is an in- 
valuable instrument in the scientist's cam- 
paign to penetrate the unknown. 

For your benefit: Development of the 
"memory" tube is another basic ad\ance 
pioneered at RCA Laboratories. Contin- 
ued leadership in science and engineering 
adds value beyond priec to any product 
or service of RCA and RCA Victor.

GENE HANKINS 

Donald Gene Hankins, senior in civil 
engineering, is the ASCE choice tor "In- 
troducing." 

Gene, a native of Effingham, gradu- 
ated from Altamont High School in 
1043. From high school he went to 
Eastern Illinois State Teachers College. 
In his sophomore year he was elected 
vice president of his class and was men- 
tioned in iriio's [f ho in J/iur'utin (Jol- 
lee/es and I ^iiivrrsitics. 

In December, 1944, (lene started an- 
other chapter in his life history by join- 
ing the Xa\y as a radio technician. June, 
1945, found Gene studying electrical 
engineering at Princeton under the 
XROTC plan, but in Jime of '46 the 
\a\y gave him an honorable discharge. 

.After leaving the Navy, the new Mr. 
Donald (i. Hankins worked for Oil Ex- 
ploration Incorporated where he did 
seismic exploration over a period of two 
years. He also spent one simimer as a 
"rough-neck," or derrick-hand for a 
wildcat oil-man. 

In the fall of 1948 Gene entered the 
I'niversity of Illinois as an embryo ci\il 
engineer. He chose this field because he 
had seen many opportunities during the 
past. His present University grade av- 
erages over 4.5. 

Gene plans to work for the Bureau of 
Reclamation after graduation so he can 
gain valuable experience. He is work- 
ing toward a commercial pilot's license 
in the Institute of Aviation because he 




hclicxcs that ll\iiig will be useful in his 
future. 

(jcne Hankins is a member of Chi 
Epsilon, Tau Beta Pi, and Sigma Tau 
honorary fraternities. He has also spent 
two semesters on the Engineering Coun- 
cil as a representative of the ASCE.

himself clearly and concisely in intelli- 
gent engineering reports," said Professor

PROF. RALPH L. COOK 

Ralph L. Cook, when asked what he 
considered the prime requisite of a good 
engineer. 

This advice might well be heeded by 
future engineers, for it comes from one 
who is well qualified to make such a 
statement. Professor Cook, who holds 
a Ph.D. in engineering, has received a 
liberal education from the school of ex- 
perience. 

Professor Cook, born in Erie, Pa., in 
1912, accomplished his first goal towards 
becoming an engineer when he graduated 
from Wesleyville High School in 1930. 
He then enrolled in the School of Engi- 
neering at the L niversity of Pittsburgh, 
which he attended for one year. 

Thence to the University of Alabama, 
where he received his B.S. degree in 
1934 from the School of Chemistry, 
Metallurgy, and Ceramics. 

Attesting to his scholastic achieve- 
mnnt was the fact that he received hon- 
ors three vears. 



Mr. Cook was soon employed at the 
General Electric Erie Works Labora- 
tory. His work pertained to the devel- 
opment of porcelain enamel used on re- 
frigerators. 

In the fall of 1938 he joined the staff 
of the University of Illinois as an in- 
structor and enrolled as a graduate stu- 
dent. In 1940 he received his M.S. 
degree in ceramics engineering and his 
Ph.D. in engineering. 

In the summer of 1945 he was a 
member of a group of scientists sent by 
Wright Field on a special mission to 
Germany. The purpose of this mission 
was to aid in the evaluation of technical 
documents formerly owned by the Ger- 
mans. 

After completing this mission, Mr. 
Cook returned to the U. of I. where, in 
1947, he received his full professorship. 
Besides teaching courses in porcelain 
enamels and bodies and glazes, Professor 
Cook also has done research on porcelain 
enamels and whiteware — bodies and 
glazes. 

Proof of the fact that Professor Cook 
"practices what he preaches" is illustrat- 
ed by his several outstanding articles 
published in the Journul of Aiiur'uaii 
(ceramics. 

Professor Cook is technically well- 
suited to his position. This, coupled 
with a warm, magnetic personality and 
a desire to constantly forge ahead into 
new developments, well qualifies him for 
the title of one of the most effective in- 
structors of the year.

THE TECHNOGRAPH 




Fingers ofjlame that pierce solid rock 



Yes. through a dramatic new process known as jet-piercing 
. . . holes can now be burned straight and true tlirough 
solid rock ! The harder the rock the more efficient the oper- 
ation! A special combination of oxygen, fuel, and water 
does the job . . . and in a fraction of tlie time required by 
the old drill attack. 

This process is of particular significance to the steel in- 
dustry today. W hy? Because goyernment surveys show that 
Americas reserves of top-grade iron ore— source of steel- 
are fast being reduced. But there remain almost inexhaust- 
ible beds of the once scorned low-grade iron ore called 
/aconite. 

The extremely hard and dense nature of taconite makes 
usual mining methods too costly and impractical. But the 
jet-piercing process— 7<';7A 1 ^10 the equipment and at a 
reasonable co^/— will burn holes straight into the solid taco- 
nite so that it can be blasted into lumps of usable size. 

Also, destructive abrasion from the sharp-edged rock on 
loading and crushing erjuipment is being better controlled 



by machine parts made from extra-hard alloy steels. And 
to concentrate the iron content of the ore, new chemical 
processes can flush away much of the "waste" matter— thus 
leaving an ore 30% richer, for more efficient smelting. 

The people of Linion Carbide created the jet-piercing 
flame process as well as many of the alloys, chemicals, and 
other materials essential to today's mining efficiency. And 
I CC stands ready to help solve problems in other fields of 
American enterprise . . . wherever better basic materials 
and better processes are needed.

The IAS at O'Hare 

Ronald Sak, Aero. Enq., '53 

( )m N(]\cnibi'r 2.\ I94Q, a group of 
IAS mfiiibeis attt'iuled a tour of O'Hare 
I'icid locatt'd at Mannheim Road and 
I )c\ on Street. .Most of the field is under 
the supervision of the I'.S. -Air Forces, 
tlie remainder is supervised b\- the Ci\ii 
.Aeronautics authoritx. 

Sergeant I^evries of the reguhu' Air 
Forces conducted the group to all the 
high-lights of the base. 

The first section \isited was the mu- 
seum of the field. Here many world- 
famous aircraft are awaiting shipment 
to the Smithsonian Institute. Each has 
achieved distinction from other aircraft 
by completing its ser\ice in an outstand- 
ing manner. 

In the American section were the fol- 
lowing: one of an early series of B-17's 
( this particular one was used to evacu- 
ate officials from the Philippines), an 
early F-51, Bill Odum's Beechcraft 



Monanza, .Mi.\-.Master nulitary gliders, 
and a few small liaison ciaft. 

In the Japanese group were the Zckc. 
Tony, Zero, Kate, liaka (the suicide 
craft), anil a modern version of the 

'I he (jerman section consisted of the 
first ram-jet flving wing, funker 117, 
Hcinkle 111, Folkc- Wolf '290, and a 
Messerschmidt 109. Planes like these 
are accredited, to a certain extent, for 
their help in making history. 

Outside on one of the landing strips 
the group was shown the /^-29 that 
dropped the first atom bomb over Japan 
— the Enola Gay! 

The members who brought their cam- 
eras with them, were permitted to take 
as many photographs as they pleased — 
pro\iding the\' were taken outside the 
hangars. With this consent, Wayne 
Jackson, one of the members, started 
shooting some angle shots of the aircraft. 
One photo included Mr. Zanotti, the 
group's sponsor, and members. Further

W'hile this was going on, Ray Kramer 
climbed into the cockpit of an AT-O. 
which was also present in the area. After 
making himself comfortable he acquaint- 
ed himself with the controls and the wa\' 
they would respond. His career was cut 
short when he noticed the group walking 
toward another building. 

Together once again, the group pre- 
pared to learn as much as possible about 
the brains of all air traffic. All con- 
trolling is done from the base operations 
building. In order to avoid confusion, 
two departments are utilized. The first 
one to be considered is the chart room.

and other information concerning other 
parts of the country are available for im- 
mediate or future reference work. 

The second department has the job of 
checking on all flights listed. The fol- 
lowing example illustrates the import- 
ance of this department. 

A pilot takes off at 8:4.^ a. m. and is 
expected to reach his destination at 
12:15 p. m. of the same day, but when 
12:15 comes around, he doesn't arrive. 
The take-off and destination airfields 
work together as they start the search. 
The flight route is the first to be consid- 
ered ; if it is all right, it serves as a sig- 
nal to check with all the small airfields 
and stations the pilot might come in con- 
tact with. Locating the last one they 
begin the air search from that point to- 
ward the next station. Within a few 
short hours the victim of an\' unusual 
circumstance is found. 

Later the group was conducted to a 
large hangar where several (j-46's were 
undergoing repair work and major over- 
hauling. Everyone entered, at one time 
or another, one of these craft and was 
allowed to handle the controls. The in- 
terior has plent\ of cargo room, but in 
the cockpit all available space is used for 
instruments. It was surprising to find 
out how high the cockpit is from the 
ground. 

Farther down the assembly line stood 

a powerful light bomber — an A-26. The 

inspection of this aircraft went so far as 

to have some members climbing on the

THE TECHNOGRAPH 




The world is tuned to pipes like these 



Petroleum, as a fuel and as a lubricant, 
has become the basic material of progress 
— and petroleum products could not be 
made available in great quantities at low 
cost if it were not for pipelines. 

Oil transporters pioneered low-cost, 
long-haul methods of handling liquids in 
large quantities. Today the users of oil 
(which includes just about everybody), 
and of many other products as well, live 
better because petroleum research men and 
engineers found ways to get the job done. 

Here at Standard Oil we are developing 
new methods to increase the efficiency and 
economy of pipelines. Externally, our 



lines now have cathodic protection; an 
electric current is imposed on the line to 
prevent dissolving the metal of the pipe 
at points where it is in direct contact with 
soil. Internally, corrosion is inhibited by 
the injection of sodium chromate solutions 
that form a protective film. Both meth- 
ods minimize costly shutdowns of our 
pipelines. Even more improved methods 
are now being sought. 

From their work with pipelines, as from 
their work with all other phases of our 
business. Standard Oil scientists can feel 
the satisfaction of accomplishment and 
the chaUenge of all that remains to be done.

lower row of fiiiislics arc known as tin- 
ailiiiiiK brushes. 

Kach of these rows of brushes is elec- 
trically connected to a row of plug hubs 
or openings on the plugboard, a switch- 
board-like arrangement on the machine. 
On this same plugboard there are also 
plug hubs with electrical connections to 
the counters or adding mechanisms of 
the machine. By means of remoxablc 
wires with plugs on either end, any 
brush or group of brushes ma\- be readily 
connected with any counter or group of 
adding mechanisms. 

Cards are fed into the machine \erti- 
cally with the bottom or the "nine" 
position first. As they move through the 
machine, they pass between these rows 
of brushes and opposing brass contact 
rollers. When a hole appears in the card 
at any position, the brushes pass through 
the card, touch the brass contact roller, 
and complete an electric circuit. If the 
appropriate brushes are connected to a 
counter by means of the plugboard, an 
impulse will be given to the comiter 
causing the machine to add the amount 
indicated on the card. 

(jountcrs 

This adding operation is accompanied 
by means of a series of counter wheels 
mounted on a constantly running shaft 
to which they are connected by means 
of a clutch. The counter wheel is nor- 
mally motionless. When a punched hole 
is reached at any position on the card in

tact between the adding brush and the

contact roller causes the clutch to be- 
come engaged, and the counter wheel 
re\-olves. The clutch remains in the en- 
gaged position until the zero position on 
the card is reached when it is auto- 
matically disengaged. This is diagram- 
matically indicated in Figure .\ 

A card punched in the number four 
position is shown passing between the 
brush and the roller. Since the card is 
punched in the number four position, 
the clutch will not be engaged until 
flu- mimber four hole reaches the brush. 
WHien the clutch is now engaged, the 
wheel will revolve until the zero posi- 
tion on the card is reached. As the revo- 
lution is in proportion to the number 
of positions passed between the punched 
position on the card and the zero posi- 
tion, the wheel will move four vmits. 

If successive additions cause the coiui- 
ter «'heel to pass the number nine posi- 
tion, in other words, if the total is ten 
or greater, an electric carry-over causes 
the next counter wheel to move the nec- 
essary one unit. 

Counters are permanently attached to 
groups of type bars (print blanks) which 
automatically print the accumulated 
totals when the last card of a given 
group passes through the machine. By 
means of a somewhat intricate system 
which will not be discussed here, the 
machine is also able to print alphabetic 
characters. Through the use of these 
mechanisms, the statements and docu- 
ments previously' mentioned c an be

greatly simplified the process of regis- 
tration. 

At registration each student is gi\en 
a stack of IHM canis. This stack con- 
sists of: \o. I. authorization card; Xo. 

2, dean's program card ; Xo. ?>. record- 
er's information card ; possihly No. 4, a 
veteran's status card ; and se\ eral Xo. 5 
cards, class cards. 

The Xo. 1 card li.is hi-i'n piexiouslv 
punched and contains such \ital infor- 
mation as name. II) number, hours 
earned, hours carried, home town, 
father's occupation, date of birth, church 
preference, college, curriculum, class, 
whether the student is new or has been 
in the I ni\ersit\- before, the high school 
percentage rank, \eteran status, sex, and 
a .sequence number for purposes of alpha- 
betic listing. 

The Xo. 2 card contains the student's 
program for the semester. Xo. 3 contains 
the same information as the Xo. 1 card 
but in a written rather than punched 
form. It is on tiiis card tiiat the stu- 
dent notes an\ ch.inLic in the infoinia- 
riori gi\en on tlie Xo. I caid. 

Cards Xos. 6 and 7 also are used. 
I liese cards also li,i\e been been pre\ i- 
ousiy punched and are gi\'en to the stu- 
dent just prior to the completion of 



registration. Xo. f> is the fees card and 
contains all of the information required 
b\ the bursar's office. Xo. 7 is the II) 
card. 

I pon completion of registration, the 
student s stack of cards is sent to a con- 
trol clerk. The control clerk checks all 
of the cards to insure that none are 
missing, checks the II) number on each 
card with the ID number on the Xo. 1 
card to insure that no card is in the 
wrong deck, and checks each class card 
with the program card to insure that a 
class card is present for each class listed. 

The deck is then "gang punched. ' 
That is, the information 0[i the .Xo. 1 
card is punched on the whole deck. This 
is accomplished at the rate of 100 per 
minute. 

The cards are then sorted into their 
\arious types and counted. This is done 
b\ the sorting machine previously de- 
scribed. To the sorter is attached a 
counting mechanism which counts each 
group as it falls into its respective bin. 
This machine is capable of handling 450 
cards a minute. 

Class cards are next ^ent to an inter- 
pieter, which prints the punched infor- 
mation on the top of each card. The 
cards are next .sent to a sorter where 
they are sorted according to college and 
class. This is done daily during registra- 
tion. 



Before class cards are .sent to the in- 
structors they are duplicated. The dupli- 
cates are combined with the other cards 
\\hich also have been duplicated and all 
of the cards are combined into one deck 
which is identical with the deck which 
was originally received by the tabula- 
ting office. The.se decks are then placed 
on file at the tabulating office for future 
reference. 

The dean's program card is then sent 
to the interpreter which prints the in- 
formation on the card in the same man- 
ner as it was printed on the class cards. 
These cards are then filed and held un- 
til the end of registration at which time 
they are sent to the deans of the re- 
specti\e colleges. 

Xext, the recorder's information card 
is put into the interpreter. After the in- 
formation has been printed upon it, the 
card is put on file at the tabulating of- 
fice. This file gives a permanent address 
file from which both local and home ad- 
dresses can be obtained. 

At some point in the operation, the 
cards pass through a tabidator which 
prints all of the information about the 
student, including his program, on slips 
of paper which are called coupons. This 
machine prints six coupons at a time and 
is capable of printing 12 to 15 programs

THE TECHNOGRAPH 




Plastics where plastics belong 

for high dielectric and structural strength, 
light weight and ease of machining 



In the RCA television camera, for example, Synthane was 
selected for coil forms, tubes, flanges and other components 
because of its electrical insulating properties, especially at high 
frequencies and high voltages. Its ease of machining, light 
weight and structural strength were other factors that led 
RCA's design engineers to select Synthane as the best possible 
material for this job. 

Synthane, laminated phenolic plastic, is at its best in appli- 
cations requiring unusual combinations of characteristics. Its 
excellent electrical insulating ability, combined with ease of 
machining, light weight, rigidity and many other properties, 
such as moisture and corrosion resistance, make Synthane a 
valuable material for many industries.

pd together in one long strip, they must 
be torn apart. This is accomplished by 
means of a mechanical "bursting" ma- 
chine which separates the copies and 
stacks them. These copies are then dis- 
tributed in the same manner as the old 
study lists were. 

Thus a great deal (it tlie ie|ietiri\e 
writing which the student u'as forced to 
do has been eliminated. Now, instead of 
filling out eight or ten study lists, the 
student needs only to write this infor- 
mation on two or three cards and copy 
his ID number on the rest. Also, this 
new system facilitates the preparation of 
many reports which previously would 
ha\e been too laborious and complicated.

A third blower has in the meantime 
made the flat base which is securel\

very hot and so pliable that it can be 
cut with shears like a piece of paper. 

After being cut to the right size, the 
bulb is shaped and finished. The last 
step consists of a sharp blow which sev-

The Biggest Job 

The 20()-inch disk for the Palomar 
Observatory has been called the greatest 
single undertaking in glass manufacture. 
The disk is actually 201 in in diameter, 
is 26 in thick, and weighs 20 tons. The 
glass was of the borosilicate type and 
was poured into a large oven containing 
the molds. The grid structure of the 
disk allows multiple support which is 
very necessary since no deflection caused 



by the weight of the minor can be tol- 
erated. 

Two disks were made, but the first 
fell victim to an accident in casting. The 
second was perfectly cast and the cooling 
process took 12 months.

1 he most familiar and commonly seen 
type of glass-workers are those in carni- 
vals and such. These people start with 
ready-made glass tubing and cane and 
end up with almost anything imaginable. 
They do their work by heating the 
glass with a small burner on a table as 
is done in Noyes Laboratory where 40

The glass lab in Xoyes is run by Mr. 
Leon F. Goodyear, who came to Illinois 
in 1947. He will make about anything 
that can be made from glass but restricts 
his work to chemical equipment. The 
lab itself is reputedly the best equipped 
in the Big Ten. The largest piece of 
equipment on hand is a Hoskins electric 
annealing furnace which has a maximum 
temperature of 2000° C The only other 
large piece of eqiu'pment is a lathe which 
is designed to hold large pieces which 
can not be hand-worked easily.

• There is more than mere identification value in the 
ridge you see on Okonite wires and cables. The ridge is 
proof that the insulation has been folded around the con- 
ductor by the well-known Okonite strip insulating process. 
This method permits inspection at all times during the 
application operation. It assures the perfect centering of 
conductors so important to the avoidance of electrical 
failures. 

The ridge is a permanent mark of an Okonite cable. It is 
still prominent after the final vulcanization in a metal mold 
that insures equal transfer of the heat throughout every 
portion of the insulation. The Okonite Company, Passaic,

more and better food on the Ameri- 
can table. At the same time, in many 
other fields, Du Pont is helping to 
raise the American standard of living 
with continuous research aimed at 
developing new products and improv- 
ing present ones. 



"MARLATE" 50 kills flies and many olhcr 
insects attacking livestock, vegetables, fruits 
and forage crops. 



BAD MEDICINE for flies 

Research that produced an insecticide safe to spray 
on cows may save millions for American agriculture 



Armed with only a fly-swatter, the 
farmer would get nowhere in ridding 
his dairy barn of disease-carrying in- 
sect pests. But he has to be careful 
in using insecticides around cows. A 
toxic spray may be absorbed through 
the animal's skin and show up in 
meat, milk and butter. 

Next fly-season farmers and 
ranchers will be able to buy a fly- 
kiUer that is both powerful and safe. 
In Du Pont Marlate* 50';, techni- 
cal methoxychlor insecticide they will 
get this combination of properties 
that no single insecticide has ever 
offered before. 

Methoxychlor is a recent Du Pont 
development. Du Pont scientists 
worked for eight years in the labora- 
tory and in the field to develop its 
applications in agriculture. 

A safer insecticide 

"Marlate" 50 is a residual insecti- 
cide and remains an effective killer 
of flies, mosquitoes, fleas and lice for 
several weeks after application .When 
used as directed, this insecticide is 
exceptionally safe to human beings, 
livestock, pets and crops. This has 
led federal experts to recommend it 
not only for spraying in barns, milk 
houses and milk plants, but also on 
the animals themselves. 

Besides its use on hvestock, meth- 
oxychlor kills many insects that at- 
tack vegetables, fruits and forage 
crops. It is offered to flower growers 
as an ingredient in Du Pont Floral 
Dust. It is used in moth-proofing 
compounds so that dry cleaners can 
easily moth-proof woolens while 
cleaning them. Many stores carry 
aerosol bombs containing methoxy- 
chlor for household use. It can be 
used with safety in flour mills, freez- 
ing and canning plants, grain stor-

age elevators, cereal manufacturing 
plants — wherever food is processed. 
This development of research can 
bring immediate cash savings of mil- 
hons of dollars to American agricul- 
ture, industry and homes. 

The long fight 

Exciting as the future of "Marlate" 
50 appears, this does not mean that 
the use of other insecticides will not 
continue. Each has its special char- 
acteristics, and each has special uses 
for which it is outstanding. There 
are at least 10,000 kinds of insect 
pests, of more or less importance, in 
North America, and there can be no 
let-up in the scientific fight being 
waged against them. 

Du Pont alone now makes over 
fifty different insecticides.Theknowl- 
ed ge gained in making each one speeds 
the development of the next. By

assembly. 

E. E. Class Lah 

The electrical engineering glass lab 
is a fundamental part of the E. E. Re- 
search Laboratory since the various spe- 
cial research tubes are made there. 

The glass lab consists of five rooms. 
Ont is used exclusively for chemical 



cleaning of all parts and a second room 
contains a hydrogen atmosphere furnace 
to process and clean metal parts. Since 
absolute cleanliness is necessary for the 
research tubes, the a.ssembled tubes are 
evacuated to 10 "■ ////// llg. This high 
vacuum is achieved by connecting a 
vacuum diffusion pump in series with a 
regular high vacuum pump. 

Though much of the glass blowing 
has to be done manually, some machines 
are now being used. The lab boasts hori- 
zontal and vertical gla.ss lathes, a glass 
saw, and a vertical tube sealer. A radio 
induction coil welds glass to metal and 
spot or butt welders unite metal poits. 
Stresses are spotted by a polariscope and 
eliminated by an electric .•innealing fur- 
nace. 

The fabrication supervisor is Robert 
Wagner. Mr. Wagner grew up in 
Champaign and attended the University 
(if Illinois. In 1Q,^9 he started as a glass 
blower in the E. E. lab, and when the 
laboratory was recently e.xpanded he 
was promoted to fabrication supervisor.

worked in the E. E. lab for 13 months. 
He has been in the physics lab for the

Introducing . . . 

[ (^unlniin/i from fitit/c 14) 
Detroit, wlu-rc he split his time between 
the school aiul the Ford Motor Com- 
pany, he worked for four years as a 
commercial fisherman on Lake Superior. 
Then he attended Michigan College of 
Mines and Technology, where he re- 
ceived his H.S. in \9^7'. 

After leaving school Mr. Eckel went 
to work for the Chrysler Motor Com- 
pany in powdered metallurgy. After 
two \ears at Chrysler, he spent six 
months at Carnegie-Illinois Steel. 

In U'.iO he came to the I . ot I. as 
an instructor of metallurg}'. He made 
use of his spare time here by working on 
his M.S., which he received in 194^. In 
1944 Mr. Eckel became E. J. Eckel, as- 
sistant professor of metallurgical engi- 
neering and in 1947 he became associate 
professor. 

At the present, I'mf. Eckel teaches 
advanced physical metallurgy, ferrous 
and non-ferrous metallography, and a 
course in powdered metallurgy. He has 
been given the responsibility for organ- 
izing this last coiMse. 

His magazine articles include the fol- 
lowing: "Method for Measuring Au- 
stenitic (iirain Size of Steel" and "A 
New Hardibility Test for Shallow- 
Hardening Steel." He has also written 
a University of Illinois bulletin on 



"E\aIuation of Quenching Media." 

Mr. Eckel somehow finds time to 
work in bis garden. Last year he filled 
12 ( 1/ jl of locker space with his home- 
grown fruit. He has been married since 
1942 and has one son four years old. 
His home and garden are on Hcale\ 
Street in Champaign, just in b.ick of 
Steak and Shake. 

Professor Eckel is a member of T.iu 
Heta I'i, Sigma Xi, Alpha Sigma .Mu, 
.ind the .'\merican Society for Metals. 

He attributes his selection as a most 
effective instructor to the fact that he 
teaches "not bow to act when you are 
settled in a job, but how to get and hold 
the first job."

with his camera, snapped Kramer climb- 
ing out of the cockpit. 

Next in the tour came the machine 
shop. Here, .is the guide explained, 
many modifications and improvements 
are improvised. It is necessary for these 
parts to be made with the same degree 
of accuracy as is required by the manu- 
facturer. 

Some of the men saw the control room 
in the control tower. They were shown 
the method used to direct air traffic and 
avoid confusion. The photogs who went 



up noticed the good view of the whole 
airfield; the result was a \ery good set 
of pictures because of the unusual wa\ 
they were taken. 

When Mr. Zanotti called for Kramer 
and an answer rang back, he knew the 
whole group was present, and it was .-dl 
right to continue to the next point nl 
interest: the F-H4. Jackson, still handx 
with his camera, took two \ery impres- 
sive \iews. 

The feature attractions of the craft 
are the dorsal fins protruding from each 
wing tank. This enables the ship to 
perform at its best during high-speed 
tlights. Another addition was the pilot 
ejector, a safety measure for the pilot. 
A warning had been posted on side 
which stated : "Do Xot Operate Con- 
trols . . . Explosive . . . Detonator on. ' 

Another aircraft inspected was the 
Douglas C-47. It is a compact ship an<l 
is capable of carrying a large amount of 
cargo. It is said to be the transport 
with the most flying time ; thus the name 
given to it was the "Work-Horse of the 
Air Forces." 

This toin- helps one to understand and 
realize that an aircraft is a single 
mechanized unit designed for one pur- 
pose. The successful program achieved 
by earlier aeronautical engineers is great- 
ly appreciated by the up-and-coming en- 
gineers of tomorrow.

PROBLEM — You are designing a circular saw. The blade 
must have horizontal, vertical, and angular adjustments. 
Your problem is to work out a drive for the blade that 
permits this three-way adjustment. How would you do it? 

THE SIMPLE ANSWER — Use an S.S.White flexible shaft 
to bring power from the counter-shaft or motor to the blade. 
There is no simpler mechanical means than a flexible shaft 
for driving parts which must be adjustable. And simplicity 
In design means economy in production.

This is just one of hundreds of remote control and power 
drive problems to which S.S.White flexible shafts provide

is spent filling ( leiger counter tubes with 
the appropriate atmospheres. Most of 
the jobs he gets arc for laboratory ap- 
paratus, but he has a greater variety of 
equipment to make than the other cam- 
pus labs. 

There is no annealing furnace here 
at the present time but one has been 



ordered. A large lathe is in the lab for 
handling cumbersome pieces. This lathe 
is used a great deal for ring seals where 
concentricity is an important factor. The 
lab is also equipped with a diamond 
tipped saw that is used to cut glass. 
Polishing and grinding equipment is also 
on hand. A drill press that can be used 
to bore any size hole is used ; the abras- 
ive used with the drill is a mixture of 
water and carborundum. 

The apparatus used to evacuate Geig- 
er counter tubes was made by Mr. 
Walker. With the pump on hand he is 
able to get down to around KM ,//; 



vacuum. A new pump that has been 
ordered will enable him to reach l(h' 
cm or greater. Leaks in the system are 
tested by using a small generator which 
discharges at a pin-point. The point is 
touched to the tubing and the color ob- 
served is an indication of the pressure. 
Small leaks, with which Mr. Walker 
is troubled, cannot be detected with the 
instrument. 

The glass lab at the Betatron build- 
ing was not visited but the labs in gen- 
eral are very much the same. They re- 
ceive little if any notice but it would be

How to help a bread slicer 
carve a name for itself 

Designers of a new, 75-loaves-a-minute bread slicer 
were looking for a way to insure long-term accuracy 
and minimum maintenance. They found the answer 
in Timken" tapered roller bearings. 

Timken bearings keep the knife drum shafts in 
rigid alignment, maintain precision movement of 
parts. They require minimum attention, normally 
last the life of the machine. And they permit tighter 
closures that keep the lubricant on the bearings 
. . . off the bread. 



Why they all look alike 
to a TIMKEN bearing 

Loads from any direction — radial, thrust or combi- 
nations of both — are carried by Timken bearings, 
thanks to their tapered design. Timken tapered 
roller bearings make auxiliary thrust bearings and 
thrust plates unnecessary . . . simplify design, save 
space, cut costs.

What was the key to 
Ben FrankUn's success? 




It wasn't the one on the end of this kite string, you can be sm-e. The key 

to Frankhn's basic contributions to the progress of science and engineering 
in America was his solid gi'ounding in technical fundamentals. In America, 
the finest textbooks ai-e available to everyone. They provide the 
indispensable background in technology that has made and keeps America great. 

Many of the books in wliich you are now studying the fundamentals 

of your specialty beai- the McGraw-Hill imprint. McGraw-Hill is the world's 
largest publisher of books for technical reference and instruction, 
as well as advanced research and study. 

Today's discoveries are tomorrow's fundamentals. 
When you finish college, you will want to keep 
up with the latest advances in your field. TJien, 
McGraw-Hill magazines and books for the practicing 
engineer will report to you on aU that is new, 
necessary and important. And you'll depend on 
the advertising pages of McGraw-Hill publications 
to tell you where the latest equipment is available. 

Today in college, and tomorrow in industry, yom- 

progress depends on how well you keep up 

with yovir field. McGraw-HiU will continue to

How to make 31,000 people happy 




ONE of the biggest single housing de- 
velopments ever undertaken has 
taken its place in the panorama of New 
York City's lower East Side. It is the 
result of cooperation between private 
enterprise, the State, and the City. 

The rise of Peter Cooper Village and 
adjacent Stuyvesant Town has changed 
the face of this 80-acre section of Man- 
hattan . . . has transformed a slum area 
of tenements and factories into modern. 



roomy living quarters for 31,000 people. 

Many similar projects . . . some per- 
haps not so large, some even larger . . . 
must take form before America licks its 
housing problem. And they'll all require 
vast quantities of steel, for steel is the 
backbone of modern construction. 

Today the steel industry is looking 
ahead toward tomorrow's big projects. 
At United States Steel, a vast training 
program is going forward continually, 



preparing men to handle the many 
highly-technical jobs that modern steel- 
making involves. Many of these jobs are 
far removed physicilly from the roaring 
blast furnaces and glowing open hearths 
—at the same time, thev are absolutely es- 
sential to today's precision steelmaking. 
Through its training program. United 
States Steel is laying the foundations for 
promising futures for young men who 
meet its qualifications.

How to 
Keep a Name 

STRONG 



Names in business can lose strength 
and vigor, even as you and I. Yes . . . 
a business can die, just like people. 
Here are ways business insures 
against this end: 

Research for product improve- 
ment and new development . . . plant 
improvement for more efficient, 
lo\Ner cost operation . . . quality 
control to maintain standards ot 
production . . . student and employee 
training to energize and revitalize 
the mental reservoir. Here's an ex- 
ample of how Research helps keep 
a business vigorous: 

Grand Coulee and other mam- 
mouth hydro projects generating 
tremendous new pools of electrical 
energy, have created new problems 



in transmission. Through the great 
resources of its research depart- 
ment Westinghouse developed a 
new one-piece, oil circuit breaker 
to handle these immense capacities. 

To test it, the U. S. Bureau of 
Reclamation routed the short-cir- 
cuit output of the six, 108,000-kva 
generators at Grand Coulee Dam 
together with the back feed over 
six, 230-kv transmission lines from 
the Bonneville Power Administra- 
tion system and the Northwest 
Power Pool for a tremendous short- 
circuit test. 

The result: interrupting-capacity 
ceiling raised from 3'/^ million to 
7'/2 million kva. 

Research, plant improvement for 



efficient production and quality 
control are all dependent on another 
basic element . . . training. 

Let's look more closely at that 
element ... as it is handled by 
Westinghouse. Engineering Gradu- 
ates who join us first receive some 
months of basic training ... an 
orientation period with initial work 
assignments and product confer- 
ences. Then further training with 
specialization in engineering, manu- 
facturing, sales or other activities. 
Finally, placement. 

That is one of the ways an or- 
ganization is kept strong. It re- 
quires strength to protect a name 
whose reputation is staked on the 
commitment . . .

IMuji-in connections to the buss pro- 
\iiles a greater degree of safety as well 
as simplifying installation and removal 
of the starter unit. ( niides for the indi- 
\idual starter luiit assure that plug-in 
stabs are aligned with buss connections. 
The starter luiit can also be disconnect- 
ed from the buss without removing it 
from the structure simply by tilting it 
foi'ward in place. This enables the stab- 
in s\stcm to be used as a disconnect 
swircli when desirable. 




The new Westinghouse motor-con- 
trol center has complete baffling 
and plug-in connections to busses. 
(Courtesy of Westinghouse) 

Starter units are baffled on all tour 
sides, but wiring is not complicated. The 
right side of the baffling slides out of 
the starter assembly to facilitate work on 
the wiring runway. Tests recently con- 
ducted indicate that bafHling is an essen- 
tial feature if faults are to be confined 
to the point of origin without bvnning 
out the entire structure o) tlie motor- 
contnil mechanism. 

Fast Photo Flash 

It is possible to photograph missiles 
moving many times faster than sound 
and even to make pictures of sound 
waves themselves. 

Such pictvires are proving imalualile 
in research into the behavior of missiles 
in flight and wind-tunnel models of 
faster-than-sound aircraft. 



The fastest camera shutters can onl\' 
cut exposure time down to one-thous- 
andth of a second, which is enough time 
for a ritle bullet to travel almost two 
feet. Hence, e\|iosures in the nullionth- 
of-a-second range must be made with 
quick flashes of light rather than b\ 
means of fast shutters. 

A special photolight developed bv 
(leneral Electric gives a brilliant flash 
of light lasting only two-millionths of a 
seconil. Pictures of bullets and shells in 
flight are taken with an ordinarv' camera 
and the high-speed photolight. 

Photographing sound waves, which 
move at about 760 miles per hour, re- 
quires a high-speed flash and a special 
optical system, which can cast into shaip 
relief varying densities of air. This 
method is known as "Schlieren tech- 
nique," and iiroduces photographic im- 
ages of sound waves, which are areas of 
high compression in air. 

High-Speed Microtome 

.\ ( ieneral Klectric scientist has nuule 
wli.it is believed to be the thinnest slice 
ever made by man. 

The slice, a piece of metal less than 
two-millionths of an inch thick, was 
cut by a shock-wave which formed in 
the sample ahead of a knife-blade mov- 
ing with the speed of sound. Shock 
waves are areas of extremely high com- 
pression which build Lip in air or solids 
ill front of objects moving at high speeil. 




The slicing device, called "high-speeil 
microtome," was developed by Dr. i;. 
F. Fullaiii of the company's researth 
laboratory. To be examined under the 
electron microscope, a magnifying instru- 
iiieiit roughlv 1(10 times more powerful 
than the best light microscope, samples 
must be sliced with the .abov e-n.imed 
thickness. 

Using a shock-wave instead of .-i cut- 
ting edge to do this slicing, l)i. Fiil- 
lani has been able to make ultra-thin 
specimens of everything from delicate 
animal and plant tissues to teeth and 
metal.

Called an X-ray spectrogoniometer, 
the instrument makes its analyses by

Think of coiicreti- and alniosr inmu'- 
diately there hops into mind that all- 
embracing definition of Portland Ce- 
ment, "... a mixture of argillaceous 
and calcareous materials . . ." from the 
ASTM specifications. Since the writ- 
ing of this classic sentence, experimental 
studies have produced new trends in 
concrete construction and manufacture 
that definitely mark the beginning of 
a new building era at the turn of this 
half-century. 

One of the biggest phases of this de- 
velopment has been the increasing use 
of concrete as a decorative as well as 
a structural building material. Serving 
in this capacit}', it is technically known 
as architectural concrete; contrary to 
public opinion, such decorative design 



is no longer specif icalh' designated as 
part of the architect's work. 

The general trend of building engi- 
neering has been back toward one of its 
major origins — the days when bLiilding 
was looked upon as a craft and ci\il 
engineering and architecture had not 
yet gone their ways into different de- 
grees of specialization. Portland Cement 
Association has aptly referred to engi- 
neering as the seienee of building and to 
architecture ;is the art of building. It 
has been onl\ within the past 15 years 
that the two professions have again be- 
gun coordinating their creative work 
to produce structurally sound as well as 
artisticalh' pleasing designs. 

The metamorphosis of the master de- 
signer will not be |iossible foi' years yet 




An example of what is being done to house important municipal functions 
in attractive buildings, this waterw^orks was designed by William Dechant 
& Sons, architects and engineers of Reading, Pa., for Denver, Pa. (Cour- 
tesy of the Portland Cement Association) 



to come, since educational gears have 
not yet been shifted to give the civil 
engineers certain visual arts training, 
and there is little literature a\ailable 
on such architectural design. A gradual 
transition is being effected, however, as 
nian\ municipal and state governments 
are organizing building committees that 
are empowered to approve av reject a 
structure on the merits of its appear- 
ance alone. 

Modirn tinishing Touehes 

Despite the fact that the present-ila\

by a basic knowledge of certain pro- 
cedures required to attain such aesthetic

For a building to follow some excep- 
tionalK' decorative scheme, the oxerall 
design must be coordinated and roughed 
out by an architect. The modernistic 
approach of the painting and sculptur- 
ing of the concrete within such a build- 
ing comes Linder the interior decorating 
profession. Howe\er, it is necessar\' for 
the engineer to be familiar with the

the event. According to the general 
version, a series of explosions today 
shattered the quiet of the campus (save 
lor the shuffling feet of registering grad- 
uate students) at 4:00 p. m., C. S. T. 
Coming out of their respective buildings 
onto Burrill Avenue, spectators next 
heard an ominous rumbling emanate 
from the Boneyard Creek between Tal- 
bot Laboratory and the Electrical En- 
gineering Building. Suddenly there ap- 
peared from the Boneyard bed, between 
the pedestrian bridge and the truck 
service bridge into the E. E. Building, 
a tall geyser of spray and water that 
shot 20 feet into the air. 

The geyser, from all accounts, was 
a bright kelly green color that dyed the 
Boneyard as it fell back to the stream 
bed. 

(For the benefit of the uninitiated, 
the Boneyard is a small stream that 



wends its way through the heart of the 
Engineering College at the University, 
and continues down through the city of 
Urbana in an easterly direction until 
it meets the Vermilion and Wabash 
rivers a number of miles away. Ac- 
cording to recently established bacterio- 
logical and chemical analyses, the Bone- 
yard is reported to be contaminated. 
Steps towards its purification have been 
taken by a joint committee of the towns 
of Urbana and Champaign in hiring en- 
gineering firms to make an estimate and 
survey of the work necessary for com- 
plete sanitation of the creek bed. Lat- 
est reports indicate that engineering 
and construction action will very soon 
give the Boneyard a "New Smell.") 

During the ensuing commotion caused 
by the initial explosions, a large crowd 
of faculty and students gathered on the 
Burrill Avenue bridge for a closer 
glimpse of the unknown phenomena. 
Borrowing hip boots from the E. E. 
Building storeroom, two electrical engi- 
neering graduate students. Bob Bruce 
and Dick Campbell, heroically slid down 
the embankment to investigate the cause 
of the geyser, which, by the time of their 
arrival, had abated to a thin trickle. 



Probing on the creek bottom, they soon 
uncovered and lifted up for the crowd's 
inspection a medium-sized stone with 
an inscription in heiroglyphic letters. 

Dr. W. L. Everitt, Dean of the College 
of Engineering, received the stone after 
their return climb. Closely examining 
the stone, his face registered various 
expressions of increduality, amazement 
and happiness; then he made the start- 
ling announcement that this stone dug 
from the bottom of the Boneyard, was 
none other than the genuine Blarney 
Stone of the good St. Patrick, patron 
saint of all engineers! 

This deduction, he explained, he had 
made from an interpretation of the 
ciphers on the rock face, which were 
of a lost Gaelic tongue characteristic 
of the era 700 to 800 A. D., the approxi- 
mate time of the life of St. Pat. 

An acknowledged authority of ancient 
languages, Dean Everitt translated the 
first part of the inscription, "Erin Go 
Bragh," as "St. Pat was the first engi- 
neer." The second phrase, he explained,

how I was such a good engineei- (as 
well as th' first), the\- should adopt 
me f'r th'r patron saint.

thrown in jail, and just about kicked 
out o' school. Thus began th' first cele-

li\ed seven years as a swineherd.

hfi Li/nn Itvlt'tnul. 1'hvni. *.#.7 



Since the ilisc(>\ci\ (it rinoii, iiulusti\ 
li;is been working to tiiui newer and 
better synthetic textile fibers. The new- 
est major ciiscovers of the s\nthetic tibei 
iiulustvy ami p(is>ibiy the most important 
\et is Orhm. 

In l'54.i the employes of the I)u Pont 
C'ompan\- acetate yain plant at Waynes- 
boro. West Virginia, began hearing 
rumors of a strajige new product being 
stiuiied in the laboratories there. As the 
I'esearch team grew, word got around 



Orion lias the public anxiously 
awaiting its entrance into the 
world of fabrics. A synthetic fiber, 
(his polyacrylonitrile will help to 
replace the out-dated rayon. Not 
only are its wearing qualities 
among the best, but also industry 
will find many other uses for this 
extremely resistant fabric. 

This article tells of the develop- 
ment and possible uses of Orion in 
a very casy-to-read manner and 
explains some of the technical 
characteristics of the strong fibers. 



that the product w.as .1 new wondei- 
s\ritlu'tic; it was mysterio\isly referred 
to as "fiber A." Six years after the re- 
search at Waynesboro had started, the 
stage of development was sufficient that 
the new material could be annoimced 
as a textile yarn and named "orlon." 

Du Pont is now building an orlon 
plant at Camden, South Carolina, that 
is schedviled to begin commercial jiro- 
duction late this year. When full-scale 
production is under way, it is estimated, 
the cost of orlon will fall somewhere 
between that of r;i\'on and that of nylon. 
If it lives uji to its laborator\" tests, the 
new fabric will fill the immense price- 
performance gap between rayon and 
n\ Ion. 

This .should do a much-needed service 
to the American public, for rayon, while 
hiw in price, is also low in performance; 
n\lon, high in quality, is also high in 
price. It is understood, howe\Tr, tli.it 
(jilon will not t.alcf the pl.ice of n\lon 
,ind r.i\<in. but will onl\ supplement 
them. 

Fritiii lh( Cidiiiiil III tin Xiitllc 

Orion is made of the raw materials 
of nylon — coal, air, and water — plus two 
(ithers, natural gas and limestone. The 



I'nd product, orlon, is a polsnier of 
■ icrylonitrile, the main ingredient of 
Huna-N synthetic rubber. Since great 
quantities of acrylonitrile will be pro- 
duced in the manufacture of orlon, the 
price of acrylonitrile will drop; thus the 
manufacture of orlon may have a good 
effect on the synthetic rubber industr\'. 
A po.ssible process for the mamifac- 
ture of acr\ lonitrile in\ol\es the follow- 
ing steps : 

( 1 ) Limestone is he.ated in a kiln to 
\u-l(l Inne: 

CiCO., -^ CaO -\- CO.: 

(2) Lime and coal are heated red-hot 
in a stream of nitrogen from the air: 

CnO + iC + N., -^ 
CalCN)., + CO: 

(3) The calcium c\anide is hydrohzed 
to produce lime, which can be re-used, 
and hydrocyanic acid: 

Cn(CN)., + II..0 -> 
CaO^mCN; 

(4) Hydrocyanic acid and oxygen (from 
air) react with ethylene (from natural 
gas) to form acrylonitrile: 

IICN + CJI, -f O.. -^ 

if,o + CI I, cues. 

The acrylonitrile is then pohnierized. 
Poh'merization is a process in which the 
molecules of a substance are joined to- 
gether (end to end in the orlon process) 
to form large molecules having new 
chemical and physical properties. The 
polyacrylonitrile must be di.s.solved in a 
special solvent (such as a nitrophenol) 
to make a liquid mass. This mass is then 
extruded through spinnerets and is 
drawn as a filament through a solidify- 
ing bath. This smooth thread may be 
used to make a cloth resembling nylon, 
silk, or rayon. 

Another form of orlon, say Du Pont 
scientists, is indistinguishable from the 
finest wool in appearance anil feel. 1 his 
t\pe is produced b\- running the smooth 
orlon thread through a machine which 
puts a series of kinks in it. The thread 
is then cut into one and one-half inch 
lengths. This form, called "staple," can 
be processed h\ st.andard textile fiin'sh- 
ing methods. 

It's Toiif/h 

( )f the m.an\ superior qualities of or- 
lon, perhaps the most important is its 
strength. The tenacity of dr\- orlon is 
4.0 to 4.8 grams per denier. (A denier 
is an expression of the fineness of a fiber 



in terms of grams per nine thousand 
meters length). When wet, orlon de- 
creases in tenacity about (1.4 grams per 
denier. 

The orlon fiber has high strength at 
high temperatmes. Taking the tenacity 
ot orlon at 2S C; as a basis, Du Pont 
testers found that the ten;icit\ retained 

at a temperature of Kl (^ is 1,?7.5 per 

cent; at 73"6', 83.5 per cent; at 10(1 Y,', 
7.'i.,'i per cent; at \25°(J. 67.(1 per cent; 
and at 1 SO'^";, Sl.O per cent. 

When oilon is dr\ it will elongate 
from U) to 21 per cent under pressure; 
when wet, from 1 T to 20 per cent. 

Orion h,is not only a high stretch 
resistance but also a good elastic recov- 
ery It will recover 100 per cent from 
a two per cent stretch ; OS per cent from 
•a four per cent stretch. 

Closely related to strength are abra- 
sion resistance and flex life. Du Pont 
has conducted research to determine, in 
these aspects, the rating of orlon as com- 
|iared with other textile fibers. Fabrics 
of three and one-half ounces weight 
were tested for abrasion resistance. It 
was found that orlon, while not so re- 
sistant as nylon, is more resistant than 
any other fiber. Nylon and orlon are 
in a class by themselves when flex life 
is under consideration. According to Du 
Pont research, orlon will fail after 
.116,000 flexes; nvlon, after 380,000; 
wool, after 44,000; silk, after 5,000; 
\icose rayon, after 2,500; and acetate 
ra>on, after 200. With these data undei 
consideration, it seems probable that an 
orlon fabric will last, under normal 
wear, about se\en times as long as a 
comparable wool fabric. 

Dcfiiint to Che mil tils 
Exceptionally inert chemically, orlon 
resists degradation by many of the worst 
enemies of fabrics. No known fabric has 
absolute resistance to the action of ultra- 
violet light, a major component of sun- 
light. However, orlon has proved itself 
far superior to any other fabric in re- 
sisting outdoor exposure. 

In a test at Wilmington. Delaware, 
samples of several fabrics were subject- 
ed to constant outdoor exposure for two 
years. At the end of this period orlon 
h.ad lost only 35 per cent of its original 
strength. In comparison, the fiber most 
nearh approaching orlon lost all its 
strength in one and one-half \ears. 

Chemicals of most sorts are remark- 
ably ineffective against orlon. Orion dis- 
plays complete resistance to greases, oils, 
neutral salts, common solvents, and some 
acid salts. Its resistance to mineral acids 
is excellent; to weak alkalis, good. For 
example, .at room temperature hydro- 
chloric acid of 20 per cent concentration 
produces no detectable deterioration of 
orlon for 4*) da\s; 37 per cent concen- 
tration, for 9 (lays. Nitric acid of 20 
|ier cent concentration will start to at-

the Til liiiof/raflh was a big help, but in 
addition, Dick acquired a thorough re-

"All the world is a showroom; and 
all the people in it, salesmen." This was 
the theme of a speech to the student 
chapter by C. L Schneider, sales mana- 
ger of the Electro Manufacturing Cor- 
poration of Chicago. 

One of the points that he emphasized 
was that sales and engineering are one 
and the same. He said, "We need sales- 
wise engineers as well as laboratory-wise 
engineers. " 

Many top ideas and systems used in 
industries today, he said, were conceived 
in the minds of salesmen. The day is 
past when sales jobs were given to men 
who coulii do nothing else. Mr. Schneid- 
er recalled that Napoleon said, "There's 
a major's baton in every private's knap- 
sack," and adapted this to the present 
day with "There's an executive's job in 
every salesman's brief case." 

The out-dated definition of the sales- 
man, one who persuades you to buy 
something you don't want at a price 
too high, he said, has given way to the 
new version of one who provides prod- 
ucts that won't come back from custom- 
ers that will.

The cold barren third floor of the 
Agricultural Engineering Building was 
transformed into a modern display room 
for Farm and Home Week last month. 
Several of the ambitious ag engineers 
sacrificed part of the semester vacation 
to make the lunch stand a big success. 

In the spare corners of the third floor, 
studv rooms for graduate students are 
being built. If fellow engineers could 
see these rooms our graduate school 
might be overcrowtled. 

The ASAE members are working 
hard on the yearbook because it may 
bring the FEI award for the student

He patienth waited while one per- 
son made a phone call and another 
swept trash off a nearby desk and two 
chairs. Seated at last for his interview, 
he quietly answered rapid-fire questions 
about his life, profession, and interests. 

Horn February 15, 1921, in Buda- 
pest, Hiuigary, Professor Baron attend- 
ed the Verboczy Ciymnasium until his 
departure for America in 1939. When 
the time came for a decision about his 
future profession, he felt that chemical 
engineering was one of the least special- 
ized fields in which sciences of every 
nature coidd be applied. P^om that 
time, Professor Baron began his climb 
into a thus-far remarkable career of sci- 
entific research and teaching. 

His first step in this direction was 
enrollment at DePaul University, and 
he later switched to the University of 
Illinois, (jraduation with a B.S. in 
chemical engineering in 1943 was fol-

like countless other engineers who trad- 
eil their slide rules for guns for the 
duration of the war, he ser\ed in the 
Chemical Warfare I)i\ision as an in- 
structor in the weapon section. 

Returning to the I'niversitN' for grad- 
uate study in 1946, Professor Baron 
obtained his Ph.D. in two years of heav- 
ily concentrated study. During this 
time, he also held a research assistant- 
ship with the I niversity Experiment

Station, a teaching assistantship, and a 
Standard Oil fellowship. He received 
his assistant professorship in September, 
1949, and is at present teaching stoi- 
chiometry, unit operations, and chemical 
engineering calculations. 

In the short time that he has been on 
the teaching staff, Professor Baron's 
quiet, kind manner, his ready assistance 
to individual students, and his remark- 
able teaching methods have won him 
respect and admiration from his stu- 
dents, which they expressed b\' voting 
him the best chemical engineering in- 
structor in the f^ffectixe Teaching Con- 
test held last April. 

The heaviest part of Dr. Baron's 
present job is the research he is direct- 
ing which, as he explains it, involves 
the study of the "aspects of fluid me- 
chanics which affect the transfer of heat, 
mass, and momentum in turbulent 
fields." Investigation of the behavior of 
jets and the flow of two-phase liquids 
are tvpical of the projects now under- 
wa\'. 

Although Dr. Baron's picifessional 
and scientific research have brought him 
membership in Sigma Xi, Tau Beta Pi, 
Phi Lambda U p s i 1 o n, and AIChE, 
his outside interests run to the cultural 
channels of literature, music, and paint- 
ing, and in his luidergraduate days.

HOWARD F. BURNETT 

From Springfield, Illinois, comes 
Howard F. Burnett, an actixe senior 
aeronautical engineer. Howard came to 
the University as a transfer student from 
Western State Teachers College in 
1947, and has since participated in num- 
erous activities. These include the Uni- 
versity of Illinois (ilider Club — of 
which he had the distinction of being 
the first president — and the Institute of 
Aeronautical Sciences. He is also presi- 
dent of Oamma Alpha Rho, an aero- 
nautical honorary societ\. 

Howard's route through college li.is 
been rather devious, however. .Aftei' 
graduation from Waverly High School, 
he attended Western for one semester; 
but he interrupted his college career in 
1043 to serve as a naval fighter pilot. 
Upon his discharge in 1946, he returned 



to Western for one \ear before trans- 
ferring to the University in 1947. 

Howard is putting to good vise the 
experience gained while he was a fighter 
pilot, and is now a part-time flight in- 
structor here at the Uni\ersit\. Looking 
toward his future, he ha^ aLo .ipplicd

Yet how many of us are actively contributing 
to the constructive programs of these organi-

meetings is lax. After officers of one of our

plies to our educational experience as well as 
many other facets of life. Let's be alive! Let's 
dare to do — and let's do it with a fervent 
spirit! Every production of genius must be 
the product of enthusiasm. 

If we want our dreams to come true, 
we've got to wake up with a determined 
enthusiasm. Rupert Hughes said, "A deter- 
mined soul will do more with a rusty monkey-

Have we not each a hill to climb?

difference? 

$2,500,000 a year! 

Both hands liokl terminations used in tele- 
phone dial switcliing equipment. They look 
pretty much alike — but let's see about that ! 

The termination at left is made by the old 
method. Insulation is stripped off the wire. 
The wire is twisted around the brass terminal, 
then fastened to it with a soldering iron. That 
had to he done on millions and millions of 
connections each year. 

The termination at right is made by a new- 
machine process developed by engineers at 
Western Electric— manufacturing iniit of the

the brass connectors from a "strip" and accu- 
rately positions each on an insulator to which 
groups of 10 are fastened by eyeleting. An- 
other machine places 2(1 wires in the proper 
position on two sets of ID connectors, drives 
two small pyramidal shaped points through 
the insulation into the wire and crimps the 
brass around the wire, making a good, solid 
electrical connection. The whole job now is 
done in one-tenth the time. 

This improvement will add s2. 5(11), (Mill a

.Another new important development 
in architectural concrete is the design 
of the formwork. which has become a 
precise phase of construction detailing. 
The pressure for which the form is de- 
signed is influenced by three principal 
factors: method of placing (hand, vibra- 
tion, etc.); rate of filling forms; and 
temperature of concrete. For general 
use, Douglas fir and longleaf Southern 
yellow pine have been found to be rlic 
best all-around lumber. 

The wood, as it comes to the con- 
tractor, is first graded for form lumber. 
For the especialh' smooth surfaces, four- 
inch tongue-anil-groo\e boards are used. 
For the more orilinar>' surfaces, five- 
inch boards are used ; and where a 
heavy wood imprijit is desired, ten-inch 



boards make joint lines and impressions 
very pronounced by their "cuj'ping 
tendenc\ when they warp. To obtain 
the smoothest surface possible, the in- 
sides of the forms are lined with pl\- 
wood or tempered Presd«'ood nailed in 
place with \er\' fine tacks. Ivlaboratc 
ornamentation in concrete is obtained 
b\ preparing special molds from the 
architect's special wood-trim details. 
These special molds may be of plaster, 
metal, or wood, depending upon the de- 
tail of the ornamentation ;md the locil 
cost.

Since the success or failure of this con-

CONCRETE . . .

into coininon practice that an- well 
adapted to all types of concrete. 

Pitstrcsscd (Jon net I' 
(^ne of these new practices is tin- 
niuch-talked-ahoiit prestressed concrete. 
It is hard to judge the merits of this 
new type of reinforcing, but experts 
seem to think its potentialities are un- 
limited. I'restressing was incorporated 
in a concrete girder bridge that is now 
under con.struction in Fairmount I'ark 
in Philadelphia, Pa. On this one bridge, 
whose final cost will be >S'1 10,01 HI, a 
saving of ;?3U0,000 was made through 
the use of the prestressed design. Origi- 
nal plans had called for a stone-faced 
arch bridge, the only type of design 
well-adapted to that particular location. 
Calculations on the Philadelphia 
biidge ( the first prestressed bridge in 
the I nited States) indicated that a 
prestressed beam is about four times as 
strong as a regular beam of the same 
size. In the normal reinforced concrete 
beam, horizontal and \ertical shear 
sticsses create diagonal tension that 
must be resisted by shear reinforcing. 
In prestressed reinforced concrete beams, 
the wire reinforcing has been pre\iousl\ 
drawn to a desired stress, so that the 
entire cross-section is in a state of com- 
pression, with all the shear reinforcing 



eliminated. Creilit for this type of de- 
sign is gi\en to Professor (iusta\e .\Iag- 
nel of the I'niversity of (ihent, Hel- 
gium, who mapped the fundamental 
design for the Philadelphia bridge, and 
to the 1' rencll enguieer, I'.ugcnc l're\s- 
sinet. 

Tiu' principal niethml used to pre- 
stress these beams is base<l on the use 
of a thermoplastic material which coats 
and adheres to the reinforcing rods with 
the strength of concrete itself. In the 
first steps, this reinforcing is set and 
placed in the forms and the concrete 
is poured. Before the initial set, the 
rods are heated by passing an electric 
current through them, the bonding ma- 
terial melts, and the rods extend of their 
own accord through expansion. These 
rods arc then anchored and drawn so 
that after the final set, the thermo- 
plastic material has cooled and reestab- 
lished a firm unbreakable bond. 



fact that after a certain amount of ^t, 
excess water that is not needed tnr 
h\(lration is drawn off from the con- 
crete and squeezed out by suction. Bene- 
fits from the use of this method are 
noticeable almost immediateh : the 
three-da\' strength is increased almost 
100^, the fi\e-da\ strength is equi\a- 
lent to that ot normal concrete at 2S 
days, hardi)' ain- shrinkage occurs, and 
the resistance to freezing and thawing 
is increased several times. 

Concrete has thus turned from a 
rather cumbersome construction item 
into a vital, all-purpose building mate- 
rial. In having its plastic qualities so 
highly exploited, it may be possible and 
probable in the near futuie to pour ;i 
bridge out of a bottle. 



(J OIK I 



.Another construction procedure that 
has been used successfully in conjunc- 
tion with this prestressing method is 
the use of vacuum concrete. Advantages 
of this material, as explained by the ad- 
vertisers, are a high initial strength in 
compression, a high degree of imperme- 
ability, and an extremely smooth finish.

How to help a gearmotor 
take care of its teeth 

To minimize wear on the teeth and to insure 
smooth, quiet operation, reduction gears in motors 
like this must be held in perfect mesh, no matter 
what the load. That's one reason why engineers 
mount the gear shafts on Timken' tapered roller 
bearings. Timken bearings hold the shafts in accu- 
rate alignment. Gears are kept perfectly positioned, 
with each tooth meshing smoothly and carrying 
its full share of the load. 



Gears mesh smoothly, 

wear longer, with shafts 

on TIMKEN bearings 

Here is a typical gear-case countershaft showing 
a common method of mounting Timken bearings. 
Due to the line contact between the rolls and races, 
Timken bearings give the shaft maximum support. 
There's less chance of deflection under load. The 
tapered bearing design takes both radial and thrust 
loads in any combination. End-movement of the 
shaft is kept to a minimum. Gears wear longer- 
work better.

tack orlon after 56 days; 411 pci icjit 
concentration, after 49 days. 

Hi}ih temperatures must act for uii- 
usualK long periods of time to produce 
any degradation of orlon. Samples of 
orlon were exposed to hot air of various 
temperatures for definite periods of time. 
The tenacities hefore and after exposure 
were recorded. After exposure at lOO"^^ 
and at 123 Y> the tenacities had actually 
been improved. At 150°6' the first de- 
terioration was noticed after four days. 
I)u Pont says that the deterioration 
would be e\en less in a gas more inert 
tli.in air.

Many properties of orlon will ,ip|ical 
to rlie domestic consimier. ProbabK the 
most welconie of these properties will be 
its non-wrinkle tendencies. Besides being 
naturally wrinkle-resistant, orlon can be 
heat-set to gi\e it a crease and more 
wrinkle resistance. Prospective users of 
orlon will be glad to learn that it has 
absolute resistance to insects such as 
moths and to microorganisms such as 
mildew-producing fungi. Allergic indi- 
viduals should have no trouble with 
orlon, for exhaListive investigations have 
proven that neither orlon nor the poly- 



acrylonitrile from which it is made cause 
dermatitic or toxicological effects. 
Ji'dtir-IIatir 
( )ne property of orlon, its ludropho- 
bic tendency, is both desirable and 
troublesome. When orlon is u ater- 
■ibsorption soaked, its moisture pickup 
is onl\ twr) to three per cent. This ipiai- 
ity is favorable in preventing shrinkage 
and dirt pickup. In a water bath at 
100 (^, orlon has a shrinkage of from 
zero to two and one-half per cent. The 
low moisture-absorptiveness prevents 
moist\ire-laden dirt from becoming im- 
bedded in the openings of the fabric. 
This property makes orlon resistant to 
many stains as well as to smoke, soot, 
and dust. Orion's hydrophobic qualitv 
also presents a difficulty — dyeing. Orion 
will not "take" most of the dyes used 
toi' coloring ordinarv' hvclrophilic fibers. 
1 )u Pont reports that standard dyeing 
techniques with some acetate and basic 
colors yield pastel hues having excellent 
wash-fastness and average light-fastness. 
When used with a carrier (dyeing cata- 
lyst, c. tj., mcta-cresol at two per cent 
bath concentration) these dyes may pro- 
duce medium shades. Heavy shades can 
be obtained by dyeing orlon under fif- 
teen to twenty pounds steam pressure. 
Lnder this pressure certain other d\es 
may be used for surface coloring with 
special techniques. 



Printed orlon can be produced by the 
use of basic, acetate, and certain \,it 
colors with ordinarv processes ;ind 
steam-pressure aging. 

Research is constantl) uiuler wa\ ; 
(111 Punt chemists and engineers expect 
to ha\c perfected more satisfactory dye-

Electronics 



GLAMOUR GIRL -OR 
PRODUCTION WORKER? 



bv H. A. BARTLING 

Miinager, Electronics Section 
General Machinery Division 

ALLIS-CHALMERS MANUFACTURINti rOMrANV 

(Graduate Training Course 1927) 




SO MANY near-miracles, actual, experi- 
mental or imaginary, are being at- 
tributed to electronics that it's quite the 
glamour girl of the electrical industr). 
, Working closely with 

«this infant prodigy, we 
^i^<^_ find it is indeed fascinat- 

ing and astonishingly 
versatile. We find, too, 
that it is a terrific work- 
er. Applying electronic 
principles to tough, 
matter-of-fact indus- 
trial jobs is the work of 
H. A. BARTLING this scction. 

It rewards us with some really amazing 
success stories, and with abundant oppor- 
tunity. The field has hardly been touched. 

New Field 
This field of industrial electronics was 
completely unknown, of course, when I 
received my degree in Electrical Engi- 
neering from Illinois and entered the 
Graduate Training Course at AUis- 
Chalmers in 1925. During the 2-year 
course I stuck pretty close to electrical 
work — and at its completion, I was on the 
electrical test floor helping run tests on 
some of the first big blooming mill motors 
the company ever built. 

Next, I worked in the Basic Industries 





Hardening 2200 trimmer blades per hour, this Allis-Chalmers Induction Heater 
is stepping up production lor a Southern manufacturer of textile machinery. 



Department on electric mine hoists. In 
1931, I moved back to the Electrical De- 
partment, doing sales application work 
for the Motor and Generator Section. I 
worked, successively, on unit sub-stations, 
had charge of the Mixed Apparatus Sec- 
tion, was in Industrial Sales, handled 
contract negotiations and sales liaison 
work during the war, and in 1947 took 
charge of the company's growing Elec- 
tronics Section. 

Here we develop and apply four main 
classes of industrial electronic equipment : 
Rectifiers, Induction Heaters, Dielectric 
Heaters and Metal Detectors. With the 
exception of Rectifiers, this equipment is 
relatively new to industry. We're turning 
up new uses and applications every day. 
It's an absorbing line of work, and pio- 
neers an entirely new frontier of indus- 
trial methods. 

Wide Choice of Interests 

I've traced this brief personal history to 
illustrate the widely varied opportunities 
a young engineer finds at Allis-Chalmers 
even within a single field such as electricity. 
I never got far from the Electrical De- 
partment, because I found what I wanted 
right there. But I wouldn't be giving a 
true picture of Allis-Chalmers if I didn't 



touch on the other great departments, 
covering just about every major industry. 

Many GTC students find their greatest 
interest and opportunity in the Basic In- 
dustries Department. There they design, 
build and install the machinery for min- 
ing, smelting, cement making, flour mill- 
ing, oil extraction, food and chemical 
processing. Others become interested in 
hydraulic or steam turbines, the com- 
plexities of centrifugal pumps and the 
engineering problems of small motors or 
V-belt drives. 

Some fit into engineering and design. 
Some find themselves most interested in 
manufacturing or in field work such as 
service and erection. Many like selling, 
and find their engineering training pays 
off" best in a District Sales Office. 

Whatever a man may eventually find 
most to his liking and advantage, the 
Allis-Chalmers GraduateTraining Course 
is a wonderful vantage point from which 
to start. It offers contact with all major 
industries, and a chance at many types of 
work : design, manufacture, research, test- 
ing, installation, selling, advertising, ex- 
port. There is no other organization that 
can offer a graduate engineer such a wide 
ranize of activities.

(.'lu'mical liicitiu'ss orloii inaki-s good 
filter cloths. Orion nets for dyeing ny- 
lon hose are already in experimental 
use. Since the orlon is resistant to the 
d\fs used fur nylon, tlu'sc h.igs .ihsorh 
little of the d\c intended tor tile n\ - 
Ion. 

Orion's great strengtii :nul it^ ni(jil- 
crate price will fit it for such ruggeil 
ii.ses as marine cordage, tarpaulins, and 
conveyor belts. The power of orlon to 
resist penetrating dust makes it an ex- 
cellent fabric for dust filter bags. For 
products requiring over-all resistance. 
materials such as electrical insulation, 
orlon should be ideal. 

In the 1 1 (inn 

.Mthougli the uulustrial uses of orlon 
will be most important at first, much 
of the fiber will be used directh in 
consumers' goods. The first \ear's pro- 
duction of orlon will go into the manu- 
facture of drapes and curtains — drapes 
which will not fade or deteriorate in 
sunlight; easily-washable curtains which 
need neither stretching nor ironing. He- 
cause of orlon's wrinkle-resistant, heat- 
setting qualities these curtains and 
drapes can be set permanently to an\ 
crease desireil. Orion's resistance to 
chemicals and heat enables these cur- 



tains and drapes to be washed in hot 
water with any reasonable detergent or 
.soap. Yet there will be few occasions 
for washing these articles because of 
their resistance to dirt, smoke, and soot. 
Orion's strength and its resistance to 
outdoor exposure, ultraviolet light, 
.•ici<ls. heat, ami nu'cro-organisms sug- 
gest use in such articles as sails, long- 
lite awnings, convertible tops which do 
not deteriorate, and fabrics for tropical 
climates. 

I'lrs'iniil I 'SI'S 

When orlon has proved itself to con- 
sumers, it will move into the clothing 
industry. It is likely to find extensive 
use in water-repellent clothing and 
bathing suits. I)u Pont has sent experi- 
mental orlon overalls to its various 
plants. The overalls are excellent be- 
cause of their resistance to the usual 
industrial plant hazards: acids, alkalis, 
lieat, wear, odor-absorption, and stains. 
N\lon shirts which need no ironing are 
being .sold today, but the price is high. 
In a few years men will have orlon 
shirts which will be considerably cheaper 
and somewhat better. 

The advent of orlon carries with it 
a promise of men's suits that are mod- 
erately priced, moth- and mildew- 
resistant, wrinkle-proof, stain-resistant, 
dirt-resistant, washable, and quick-dry- 
ing. Like the shirts, these suits should 



lujld a perfect crease with no pressing. 
These is another interesting possibilitx 
for orlon in men's clothing: orlon ma\ 
replace the rayon being used for pin- 
stripes in wool suits. While the rayon 
shows dirt easily and wears out faster 
than wool, orlon is dirt-resistant and 
xxould outwear the rest of the suit. 
Women \\ t\\ tmd oilon not only in 
dresses and suits, but also m sheei' ;uui

These are just a few of the man\ 
applications which the versatile orlon 
fiber will find m industrial and private

'@ DO THEY MAKB SHIPS, PAP? 



"Almost no limit, son, as long as the men who design and build them continue to take 
advantage of scientific progress in all the things that make ships strong, fast and safe. 




"Things like the ship's steel plates. 
They must be just right. Tliat's why 
the powerful rolls that form them in 
steel mills are kept smooth and true 
with big Norton roll grinders and fast- 
cutting Norton grinding wheels. 




"So, you see, Bruce, in these ways and 
many more Norton has a hand in mak- 
ing modern ships bigger and better... 
another proof that I'm not boasting 
when I say 'Norton makes better prod- 
ucts to make other products better'." 





"To give today's floating cities extra 
speed and smoother sailing, propellers 
must have perfect surfaces . . . the kind 
that come from rough-grinding with 
Norton cup-shaped wheels and finish- 
ing with Behr-Manning abrasive discs. 



"Yes, and attention to fine details is the 
sign of the wise ship designer. That's 
why the terrazzo floors in galleys of 
ships like the 'Queen Mary' get lasting, 
non-slip safety from a Norton product 
called Alundum aggregate."

Coming cleaner 



SrCH QUICK EASY CLEANING . . . [jiautically no scrubljing 
... no fading of colors ... no irritation for tender skins- 
sounds like a new and better soap, doesn't it? But it isn't 
soap at all! 

Now vou can have a modern cleaner that reninses dirt 
with unbelievable speed, yet is completely mild to the skin 
and to the sheerest fabrics. Modern cleaners carry the dirt 
away with them, and form no ring in the dishpan or tub. 

These new cleaners are made from organic chemicals. 
They are scientificallv prepared to work equally well in 
soft, hard, even salt w^ter. 

For washing dishes or clothes, for housecleaning, for in- 
dustrial uses, better clpaners are here right now— and they 
are improving every dav. 

Today's modern synthetic detergents are not soaps . . . 



they are entirely different chemically, and work in a dif- 
ferent manner. 

The peoj)le of L nion Carbide ha\e a iiiuid iji making 
many of the organic chemicals that go into these modern, 
efficient cleaners. Producing better materials for science and 
industrx— tn aid in meeting the demand for better things 
and better pcrlnrnuince— is the work of Union Carbide.

Science Makes a Belter Mop 

Cleaning tasks lightened by ne^ 
Du Pont cellulose sponge yarn 




An ordinary mop has a bad habit of 
unraveling. It often leaves a trail of 
lint. And it wears out fast. A man 
who .sold yarn to mop manufacturers 
decided to do something about these 
nuisances. Perhaps some reinforcing 
material might be combined with the 
yarn. He did some experimental work 
of his own but more and more he 
wondered if it might be possible to 
use a cellulose .sponge coating. 

THREE YEARS OF RESEARCH 

So the man called on Du Pont, the 
company that had introduced the 
cellulose sponge to America in 1936. 
The suggestion of a sponge yarn pre- 
Gented a challenging problem. 

Some way would have to be found 
to extrude a tightly fitting cellulose 
sponge jacket around each strand of 



the yarn. The whole sponge process 
would have to be adjusted for use 
in an especially designed machine. 
Du Pont chemists and engineers 
tackled these problems. 

Even the very first cellulose sponge 
yarn produced experimentally made 
mops that were strong, absorbent 
and durable. But the process had to 
be changed and improved time and 
time again. Then the mops were 
tested in places where they would 
get the hardest usage — railroad sta- 
tions, for example. 

The mops performed so v/ell that 
Du Pont built a pilot plant near 
Buffalo and, under a license from 
the man who had the original idea, 
manufactured the yarn on a small 
.scale. Only after three years of study 
and testing was Du Pont able to

in commercial quantities. 

FASTER AND CLEANER 

Mops made with cellulose sponge 
yarn pick up and retain so much 
water they need wringing less often. 
You can mop a floor with them in 
far less time than it formerly took. 
They dry quickly, leave no lint. They 
outwear other mops three to five 
times. Best of all, perhaps, they stay 
dirt-free longer than ordinary mops. 
Here is something women will ap- 
preciate — a clean mop! 

The introduction of these new 
cleaning tools is another example of 
how business firms of all sizes depend 
on each other. The Du Pont Com- 
pany had facilities for specialized re- 
search on cellulose sponge. Because 
Du Pont could supply sponge yarn 
economically , some twenty mop man- 
ufacturers today have a better prod- 
uct that saves maintenance people 
and the American housewife time, 
labor and money.

The Harmoniker 

ro'uliai lien ing-hdiK- markings, visi- 
ble on television receivers and often 
blamed on nearby amateur radio sta- 
tions, may now be eliminated in most 
cases with a new device called the "har- 
moniker." This was developed by tlie 
television division of the General l.lec- 
tric Research Laboratory. 

rhoiigh amateur radio communication 
is only one of many causes of television 
interference, the result can be especially 
.innoying and completely ruin the view- 
er's eniovinent of a program. 

Interference results not from the main 
signal sent out from the amateur station, 
but from its harmonics. Flashing neon 
signs are another source of interference. 

The harmoniker is an arrangement of 
four coils, with a.s.sociated condensers 
;iiid wiring. These are enclo.sed in a 
metal bo.x, which need be no larger than 
3x4.x5 inches in most applications. It is

It is the latest in a group of starch 
products with unusual properties de- 
veloped ill the National Starch Prod- 
ucts, Inc., laboratories. 

Called Dry-Flo, it is a finely divided 
powder with a silky texture, free-flow- 
ing to the extent that in many ways it 
behaves like a liquid. Because each 
starch granule is united with water- 
repelling hydrocarbon radicals, the prod- 
uct is not wetted by water and cannot 
be gelatinized by beating in water. It 
floats on the surface of water without 
clumping. 

If added to water-immiscible solvents, 
Dry-Flo will remain wetted by the sol- 
vent even after agitation in the presence 
of water. When moistened -with alcohol 



Reflected Radio Waves 

While ciigiiu-crs still haven't fouiiil 
a convenient way to move mountains, 
they claim they've done the next best 
thing. A. A. John.son, of the Westing- 
house Electric Corporation, reports that 
radio weaves are being "bounced" around 
a mountain in Pennsylvania. 

A microwave communication system 
recently installed between a sub-station 
and generating plant of the Pennsyl- 
vania Electric Company at Johnstown 
has shown the reflection principle to be 
both efficient and economical. The sub- 
station and generating plant are 12 
miles apart and the expense of installing 
and maintaining multiple telephone lines 
for control purposes would have been 
considerable. 

Microwaves seemed to offer a solu- 
tion. However, as in television, these 
waves travel only in a straight line ; and

PROBLEM — Your company manufactures gas 
burners of varying number and spacing of gas 
ports. You v/ant to develop a drilling machine 
v/hich can be changed over v/ith a minimum of 
time and effort to drill the holes in the different 
burner castings. How would you do it? 

THE SIMPLE ANSWER— The illustration shows 
how one manufacturer solved this problem by 
using S.S.White flexible shafts as spindles. 
This arrangement makes possible quick changes 
of spindle groupings to meet different require- 
ments. As here, S.S.White flexible shafts make 
ideal power drives for almost any machine part 
which must be adjustable. 



This is just one of the 
hundreds of remote

Some journals are technical publications. 
Some journals are the parts of rotating shafts 
that turn in bearings. 

For both kinds of journals, there's good news 
in Standard Oil's performance testing program. 
One result is a new testing device for mill and 
locomotive driving-journal grease that enables 
us to tell more accurately than ever before what 
our greases will do under actual conditions of 
use. That, in turn, enables us to proceed more 
directly with the job of making our greases 
still better. 

Standard Oil took the lead in performance 
testing, and is a leader today. During the war 



our tests furnished information that enabled 
the Army to procure certain products with 
greatly increased reliability of performance. 
Some of our tests have become a part of govern- 
ment specifications. Many users of our prod- 
ucts are benefiting, both from better products 
and from more accurate information. 

As time goes on, we are doing more and more 
performance testing. In some cases, we have to 
develop not only the tests but also the testing 
equipment. But to Standard Oil researchers 
and engineers, any effort is worth while if it 
will help make better, more useful petroleum 
products.

of major industries from coast to coast. At Dow, this com- 
plex distribution problem is solved by strategically locating 
plants, branch offices, and warehouses near the nation's 
production centers. In many instances, the much-needed 
material can be shipped overnight from Dow to processing 
plants in the vicinity. 



This close relationship to industry results from Dow's 
progress througlioul the years in production, sales and 
distribution of chemicals "indispensable to industry and 
agriculture".

Cylinder Blocks Blasted 

rhrougli tlu- application of a .special 
process for the internal cleaning of en- 
gine blocks, Ford Motor company has 
practically ruled out the possibility of 
engine trouble due to inadecpiatc block 
cleaning. 

The process employs a new shot blast 
cleaning machine that is the first of its 
kind in the automotive industry. It 
guarantees additional protection against 
core sand remaining in the internal 
c\linder block water passages. 

The new pressure blast machine sup- 
plements conventional equipment to re- 
move burnt core and molding sand and 
scale from the interior and exterior sur- 
faces of the motor block casting. 

Possibility of obstructions developing 
in water circulation, thereby creating 
faultv or broken cylinder blocks in 
cars is muiimi/ed. 

The new blasting technique w<irks 
this way: Motor blocks are brought 
b\' conveyor one at a time into the blast 
cabinet. Two work positioning arms, 
one foi' each side of the casting, register 
the block in correct position for apply- 
ing the blast of shot. The blast is blown 
through 16 no//.les under air pressure of 
S^ psi. 

The air-driven shot strikes hidden 



sand or scale, freeing it trom the metal's 
surface. The loosened material then can 
be removed from the block's interior. 

Surfaces of the water jacket, crevices 
and thin sectional openings are blasted 
clean — exposing bright virgin metal to 
the cooling water circulated fioni the 
radiator. 

The material used in the blast proc- 
ess consists of iron or steel shot and 
grit. The air blast eiiuipment operates 
automaticalh', with the blast period con- 
trolled by an automatic timer. 

Gold Container 

I'he "new look " in gold shipments is 
a sturdy, tamper-proof container made 
of transparent Lucite acrylic resin. Util- 
izing the strength and water-clear trans- 
parency of this versatile plastic, the 
new containers are designed to provide 
deliveries which are above question. The 
contents are clearly visible at all times, 
and the enclosed assayer's certificate and 
affidavits may be read directly through 
the plastic. 

The containers are sealeil by means 
of a wire, which passes through the 
sides of the cylinder and through a 
groove in the remo\able top. 1 he base 
is similarly constructed, assuring a tight, 
fool-proof enclosure. Upon deli\cr\, the 



recipietit needs only to note the en- 
closed certificates through the trans- 
parent walls of the container. This elim- 
inates time-consuming inspections. 

Atomic Timepiece 

J he first at(inuc clock, accuiate re- 
gardless of age, temper.-iture and pres- 
sure, and independent of the eaith's mo- 
rion for its method of time-keeping, has 
been developed by the National Hvn'eau 
ot Standards at Washington. 

A ,?()-foot copper tube, filled with 
ammonia gas, is wound around a special 
50-cycle electric clock. The three hydin- 
gen atoms in a molecule of ammoni.i 
form a triangular plane through the 
center of which the nitrogen atom 
swings back and forth. A very-high- 
frequency microwave signal is tuned b\ 
automatic radio devices of extreme sen- 
sitivity to the constant frequency of this 
vibration. The equipment includes a 
quartz-crystal oscillator for generating 
a driving signal at low frequency, a fre- 
quency multiplier which transforms this 
to the microwave signal, a frequency 
discriminator, and a frequency divider. 
The radio waves are shot through the 
copper tube in the proper frequency to 
match the inversion of the nitrogen atom 
in the ammonia. 

( Ciiiifnued on page 2(1) 




This new standard of accuracy in 
timekeeping is controlled by com- 
paring the driving frequency with 
a vibration frequency in the am- 
monia molecule. (Courtesy of Frick 
Company).

poivirfiil iitoiii siiuislur in the liorld — the 300-iiiillion-i'olt betatron. 

Ihii 4(>(>-ton pieic of iiuuhiiiery is expected to open the doors of one of thi 
latest phases of naelear research — investii/atioii of the meson, or liits of "atomic 
(line" as it is commonly called. 

This article explains a fere of the more f iindamental principles of the hetatron 
and the leork of its inventor. I'rof. Donald //". Kerst of the ['. of I. Physics 
Department. 



There was an almost mandible liLim- 
niing of unseen machinery as a large 
group of spectators waited for the man 
at the control panel to push the but- 
tons. They were waiting to see the evi- 
dence of the creation of cosmic ra>s 
14-billion times more concentrated than 
those showered on the earth from the 
outer universe. 

The day was February 28, 195(t; and 
the place, the Betatron Laborator\ out 
h\ Memorial Stadium. A notable gath- 
ering of L niversity officials and news- 
papermen were present to witness an- 
other great advance into the field of 
atomic science — the brand-new 300- 
million \oIt betatron. The man at the 
control panel was Prof. Donald W. 
Kerst, a member of the Physics De- 
partment and inventor of this world- 
famous atom smasher. 

The field of nuclear research now 
has three powerful methods for piercing 
the secrets of atomic structure. One of 
these, the betatron, as distinguished from 
tile other two, the synchrotron and cy- 
clotron, creates energy by the accelera- 
tion of electrons through the use of 
magnetic flux furnished by a giant mag- 
net. The c\clotron causes proton accel- 
eration with less precise control of iiii 
Iiarted energy than the betatron, but it 
does produce a greater volume of accel- 
erated particles. The synchrotron also 
causes electron acceleration ; but it ac- 
complishes this through a radio-frequen- 
c\ s\stem, rather than the flux magnet 
ot the betatron.

joined the University faculty. This first 
machine, no larger than an overnight 
suitcase, is still kept on display at the 
Hetatron building.

edition that was converted into a com- 
mercial machine for arsenals and indus- 
trial use by the combined engineering 
designs of the Universit\- and Allis- 
Chalmers of Milwaukee. 

An SO-million volt pilot model, con- 
structed in 1945-46, was the forerunner 
of the present betatron. The third and 
fourth machines were built on funds 
from the $1,S()(I,1)()0 appropriation that 
the Illinois legislature granted the Ini- 
versity for a nuclear research laborators 
and equipment in 1945.

being an interesting coordination of go\- 
ernmental and local economics to pro- 
vide the life-supply of water to fertile 
regions that once ran the gamut of 
alternate floods and droughts. 

We have all heard of the Tennessee 
Valley Authority and the Columbia Val- 
ley systems; but .still fairly unknown in 
its infancy stage is the St. F'rancis 
Ri\er Basin Project. 

Conditions Before Construction 
The origin of the St. Francis is the 
rugged hill section of Southeastern Mis- 
souri in St. Francois county. The river 
flows in a lazy southerly direction 473 
miles to its junction with the Missis- 
sippi river about 8 miles upstream from 
Helena, Arkansas. Its preseiit total 
drainage area is about S,350 square 
miles. In the hill section north of Wap- 
papello, the runoff is rapid and tin- 



stream is quite flashy. Since the estab- 
lishment of a water gage at Wappapel- 
lo in 1020, the following data extremes 
have been gathered : 

Lowest mean monthh flow — 70 cfs 
(August, 1936). 

Maximum flow stage under natLiral 
conditions — 30.7 feet (Ma\, 1033). 

(This corresponds to a discharge of 
about 82,500 cfs from a drainage area 
of 1,310 square miles.) 

Peak discharge— 85,000 cfs (August, 
1015, and March, 1035). 

Maximum recorded discharges — 30,- 
000 to 60,000 cfs. 

In the past the principal overflow 
damage has been to crops, farm im- 
provements, railroads, highways, and 
public utilities. Prior to the construction 
of the present St. Francis Basin Proj- 
ect, the average annual flood loss was 
about $1,400,000 in the St. F'rancis

PART I 

1. A tunnel is to be constructeil, the cross-section of 
uhich is to be in the form of a rectangle surmounted by 
a semi-circle as shown in Fig. 1-2. In order to make the 
most effective use of the available lining material, the in- 
side perimeter of the cross-section must be kept at 60 // 
Determine the radius r and the height /; which will gi\e the 
greatest area of cross-section for the given perimeter. 

2. Two towns A and B (Fig. 1-3) are both located on 
the west side of a river from which it is proposed that each 
secure a water supply. Town A is 8 miles from the bank 
while town 5 is 1 5 miles from the bank and 12 miles up- 
stream with respect to town A . The ri\er is straight between 
the towns. It is proposed that a single pumping station 
ser\e both towns. Determine: 

(a) The position of the pumping station on the bank 
that will make the total length of siipph pipe the 
least. 

(h) The total length of supply pipe. 

?i. Compute the currents at i, . i... and ;, of Fig. 1-3. 

4. A train traveling at 75 mph recei\es a warning that it 
is approaching a "slow signal" and the engineer immediatelv 
reduces speed at a uniform rate of 1.8 ft. /see.-, so that his 
speed is 15 mph as he reaches the slow signal. The slow 
order covers a stretch of 5 miles of track being reconstructed 
and as soon as he reaches the end of the slow order, the en- 
gineer increases his speed at such a uniform rate that the 
train is tra\eling 85 mph 90 seconds thereafter. 

(a) What length of time elapsed between the warning 
and the beginning of the slow order stretch and what 
distance did the train travel during that time? 



(b) What distance ilul the train tra\el from the end 
of the slow order stretch in attaining its speed of 85 mph.' 

(c) How long will the train have to travel at 85 mph in 
order to make up for the time lost by not running 
continuously at 75 mph? 

5. Fig. 1-9 shows diagrammaticall.\ a pneumatic buffer 
on a lift bridge. As the bridge starts to lower, the buffer 
liiston is in the position .shown and the air in the cyclinder 
is at atmospheric pressure and temperature (60° /•"). Neg-

AL MAKULEC 

Every month an outstanding; student 
is chosen from his fellow engineers, 
grilled to a deep brown and then sand- 
wiched between an outstanding profes- 
sor and a fellow outstanding student 
on these pages. 

Seriously though, a great deal of 
thought is given to the selection each 
month of the men considered to be out- 
standing in their fields. This month 
Alfred Makulcc has been chosen b\- the 
lES. As Professor Kraehcnbuel ex- 
pressed it. "There .ire nian\ outstand- 
ing individuals among this semester's 
illunu'nating engineering students, hut 
-Mr. .Makulec is a great activit) man 
.is well as a good student." 

Al admits that he enjoys his extra- 
curricular activities as well as his 




ALFRED MAKULEC 

studies. His favorite is the Illini Foren- 
sic Association — a debating group. Al 
has been president of the association 
since .May of 1940. 

Al likes to know what people think 
about his debating, so he recently turned 
inventor. He has designed what he 
terms an audience analyzer for the 
.Speech Department which is in the em 
byro stages of construction at the pres 
ent time. It consists of 12 spotter sta- 
tions at strategic points in the audience 
where the spotter can indicate his im- 
pression of the speaker and his delivery 
by turning a calibrated knob to any 



position from (I to 1 1). Zero indicates 
a poor impression and 10 an excellent 
one. The 12 station impressions are all 
averaged together and the result is reg- 
istered on a dial visible to the speakers. 
Al Makulec is a member of the na- 
tion.il debate honorary, Delta Sigma 
Rho, and Phi Eta Sigma honorary. His 
engineering activities include Engineer- 
ing council and St. Pat's Ball ticket 
sales. 

CHESTER GAWLIK 

One of the most prominent mechani- 
cal engineering students on the campus 
is Chester Gawlik. "Chet," as he is 
known to most of the engineers, is re- 
cording secretary of the SAE. 

Chet was born in Chicago, where 
he spent most of his life except for the 
two and a half years he was in the 
Co.ist (ruard. He saw duty in the Euro- 
pean Theater of Operations as a ma- 
chinist mate aboard a destroyer escort. 
I pon his discharge Chet returned to 
Schurz High school to complete his 
high school education. 

In September, I94fi. Chet einoUed 
in the mechanical engineering curricu- 
lum here at the University of Illinois. 
During his first year he became an ac- 
tive member of the Kappa Delta Rho 
fraternitv and in his last vcar he was 




elected ,is a member of Pi Tau Sigma, 
honcirarv fr;iternir_v of the niechanic'd 
enguieers. 

In Se|itember, l')4X, juvt before re- 
turning to school, Chet ilecideil that 
he wasn't going to remain a bachelor 
— and so he got married. He and his 
liivciv wife, Loiiisc, and their 7-months- 
old son have made a comfortable home 
iji the Illini Village. Although Chet is 
working while attending school, he still 
finds time to work at his hobbies.

When agriculturists want to learn 
what nourishment a plant is getting, 
they inject radioactive materials into 
the soil and trace their absorption 
with sensitive instruments. Industry 
and medicine also use this ingenious 
technique to gain needed knowledge. 

Until recently, scientists literally heard 
what was happening, for they followed 
the passage of atomic materials through 
plants or machines, or even the human 
body, with a clicking Geiger counter. 
Now a more sensiti\e instrument — a ncio 
scintillation counter made possible by a 



development of RCA Laboratories — can 
do the jol) more efficiently. 

Heart of this counter is a new multiplier 
phototube, so sensitive tiiat it can react to 
the light of a firefly 250 feet away! In the 
scintillation counter, tiny flashes, set off^ by 
the impact of atomic particles on a fluores- 
cent crystal, are converled into pulses of 
electrical current and multiplied as much as 
a million times by this tube.

"Doggondest c o n g 1 o in e r at i o n 
of things not to do that you ever saw," 
is Prof. C. C. Wiley's short comment 
about the University-owned and -con- 
tmlled light traffic signals at the cor- 
ners of (jreen and Mathews and Green 
and Wright streets. 

He referred particularly to the mas- 
ter control panel which is located in 
the subterranean depths of Civil Engi- 
neering Hall. This impressive array of 
flashing bulbs and ticking meters is 
the site of daily pilgrimages of many of 
his traffic engineering cla.s.ses. 

As seen in the accompanyijig picture, 
each set of lights has a separate control 
and a reserve control f(n' mishaps. The 
s\ iichroni/.ation comes from the master 
controller located m the centei' of the 
|ianel board. 

Professor Wiley feels that a purchase 
of a modern control luiit by the Uni- 
versit\' would not oid\' give greater re- 



liabilit\, hut would take much less main- 
tenance. However, to the imlearned eyes 
of his students, the panel board is an 
awe-inspiring symbol of their future 
\xork.

located on the front wall, controls the 
row of lights nearest the windows. 
W'hen the light switch is turned on, the

Today^s News — Today! 



The amazing speed and accuracy with which news comes 
to us are genuine trilmtes to the great newspapers, and the 
news services, to radio and television— and the people who 
staff them. 

Its a story of ronmuiiiieations. Radio flashes words— by 
voice or teletype— across continents and seas with lightning 
speed. Pictures move as fast. And today television and pho- 
tography are used in a jiiethod to transmit instantaneoush 
and reproduce full pages of printed, written, or illustrated 
matter in the on'iiinnl form! 

Electronics is the basis of such speed. Special metals are 
required for the tube electrodes. Plastic insulations keep 
high frequency current in right circuits, ("arlions uni(pic 



electrical and mechanical value is used to control power. 

In supplying these materials, and many needed chemi-

Some fast work by Council nicmbcis, 
Hob Baird, Krrol ' Rodda, ami Cail 
l\idewell, produced a list of \\ortb\ 
candidates for a new eiigineerinj; honor, 
Tlie Knights of St. Patrick. This order 
was formed to honor those senior engi- 
eers who have been particuhirl> out- 
standing in activities. 

After receiving nominations from tlie 
committee, Engine Council voted for 
the 12 most deser\ing candidates. A 4.0 
average and attendance at the knight- 
ing ceremony at St. Pat's Ball were con- 
sidered requirements for the honor. Ln- 
graved shamrock keys were given to the 
Knights after being dubbed b\ our pa- 
tron saint. 

The Engineering Convocation will 
not include an effective instructor con- 
test this year. Council felt that the 
complications of repetitive w i n n e r s 
would be unfavorable and that this fea- 
ture of the Convocation should be bi- 
ennial. 

The constitution committee has been 
working like mad making revisions for 
a more workable organization. The re- 
sults of their efforts will be presented 
soon for the engineering societies to 
vote upon. Don Savage, SAE, is chair- 
man of this important committee. He is 
being ablv supported by Rav Brown, 
SBACS, and (lerald Slusser, AIChE. 

One change in organization has al- 
ready been made; the job of secretary 
has been split into two parts. Carl Pude- 
well, lES, has been named recording 
secretary, and Jim Bienias, AS ME, is 
corresponding secretary, publicity chair- 
man, and chief coordinator. 

AIEE-IRE 
The electrical engineers are making 
effective use of their student lounge 
in E.E.B. The E.E. honorary, Eta 
Kappa Nu, and AIEE- 
IRE have jointly spon- 
Miied coffee hours that 
were both enjoyable anil 
educational. 

At one of these, Prof. 
Ross Stanger of the Psychology Depart- 
ment spoke on the engineer's adjust- 
ment in industry. At another, Paul N. 
Landis, Professor of English, discussed 
the value of literature to the engineer. 
Culture with the coffee sounds like 
a good idea! 





ASAI' 
Not to be frustrated by the co.il crisis, 
the AS.AE held its first meeting this 
semester at the residence of President 
Harold Brandenburg. 

The co-editors, I ),ive 
Ca-h and John lluher, 
(jt the ASAE annual ha\e 
received plenty of co- 
operation so that it is be- 
conu'ng a reality. The annual is known 
as 'J'lir Illinois Ai/riculitiral Engineer 
,ind will be in circulation soon. 

This publication has not only given 
the ag engineers some literary experi- 
ence, but it will serve to inform many 
people of this important field of engi- 
neering. Some copies will be sent to 
high schools and others will be sold on 
campus. 

The annual will include articles on 
new developments and research, the 
Agricultural Engineering Department, 
Ilm'.mnI and faculty, and other items 
of interest. 

Bob Camp, the business manager, re- 
ports advertising sales have progressed 
satisfactorily. The staff numbers about 
sixteen members and they have received 
much cooperation from the faculty and 
extension staffs in this first journalistic 
effort since 19J57.

tured speaker at the February 22 meet- 
ing of AES. His subject was "Ferrous 




Meltnig I'urnaces." Mr. ( iregg opened 
his talk with a brief outline of the t\'pes 
of furnaces used b\- different kinds of 
foundries. Slides enabled him to describe 
the operation of equipment useil through- 
out the foundry industr>-. 

An explanation of the constructioji 
anil operation of the cupola was fol- 
lowed by a description of the air-blast 
control equipment. Several different 
types of mechanical charging machines 
were shown and Mr. (iregg illustrated 
the labor sa\ing economics of each. 
Slides explained the various kinds of 
dust collectors, and the electric, open 
hearth, converter, malleable, and induc- 
tion air furnaces. 

The business meeting consisted of 
naming committees to develop I SEE 
projects, and an explanation of the fi- 
nancial arrangements of the St. Pat's 
Ball.

Among the activities of the AIEE 
during the fall was a trip to the NBC 
television and FM transmitter studios. 
Another interesting trip was one 
through the gigantic Fisk Generating 
station, the first steam turbine station 
built in the I nited States. The elec- 
tricals also sponsored an inspection trip 
to Illinois Bell's new long-distance toll 
building. 

Foremost of this semester's plans was 
an exhibit of electronic phenomena, 
"Words over Waves." It was conducted 
by Illinois Bell Telephone company in 
the Navy Pier auditorium Tuesday, 
March 21. 

One new activity participated in by 
the AIEE at the Pier is the sponsor- 
ship, in cooperation with the Chem 
club and the Pre-Meds, was an inter- 
esting and informative lecture, "How 
the Brain Works," delivered by Dr. 
McCulloch before a capacity audience. 
A similar affair is planned this semester 
featuring a talk on the betatron. 

The members who attended the first 
business meeting, held on Tuesday, Feb- 
ruary 28, heard an interesting talk by 
Professor Klapperich on "Electronics."

1. To briiif; about closer relationship and 
cooperation among the various profes- 
sional societies. 
_'. 'I'o stimulate the interest of the engi- 
neering student in all engineering ac- 
tivities on campus. 
.V To be responsible for tiie planning and 
carrying out of combined activities of 
the engineering societies; e.g. St. 
Patrick's Hall and the Engineering 
Show." 
This is Article 1, "Puipose anil Aims," of 
the Engineering Council constitution. It sets 
forth very clearly why the Council was 
formed and what its function should be. 

To what extent is Council effective in 
carrying out its objectives? Is it really carry- 
ing the ball and leading our engineering 
societies and our engineers to greater accomp- 
lishments? 

As far as point .>, coordination of combined 
activities, is concerned, Council has been tops. 
Last year's St. Pat's Ball and the Engineer- 
ing Convocation and this year's ball and 
1 SEE were, without a doubt, great successes 
and credits to the organization, its methods, 
ajul its members. 

Hut points 1 and 1 ha\c been somewhat 
neglected in the past years. The activities 
of Council have indirectly promoted co- 
operation among the societies and stinudated 
interest in engineering activity, but there 
hasn't been any definite concerted action to 
accomplish these specific objectives. 

There are several ways in which Council 
could be of valuable assistance to the pro- 
fessional societies and even, unofficially, the 
honoraries. Activities that will help each so- 
ciety individually will help the College, the 
Council, and the student to feel and be a 
part of the cst"it dr corps that is building up 
on campus. 

Most of our societies elect officers for one- 
semester terms. This rapid turn-over of man- 
power often causes a certain amount of con- 
fusion and lack of clear, definite plans. Prob- 



ably the biggest detriment is the last-minute 
planning of inexperiencetl officers. 

To help provide the wheels of our organi- 
zations with a clearer picture of their obliga- 
tions as officers and the potential accomplish- 
ments which they could easily attain, Council 
coidd and should do something in the way of 
leadership training. At the beginning of every 
semester there should be a get-together of 
all society officers, old and new, to really 
hash over the problems of organization and 
methods. This should be done with the dis- 
cussion guided by someone with plenty of 
experience working with engineers and their 
professional societies. 

To really do the job uji brown, an Illinois 
Engineering Societies Manual could be com- 
piled and made available to all officers and 
staff advisers. Several of the national societies 
have .some kind of informative guidance manu- 
al for use by student chapters. These could 
be effectively combined with local experience 
into a \aluable reference that would pertain 
specifically to engineering societies at Illinois. 

To stinudate the interest of students in 
engineering activities. Council must make use 
of more effective promotion methods. At this 
point, especially, the Ticlinoyral>h can work 
hand-in-hand with Engine Council. Neither 
organization can do the complete task alone. 

The Tech plans to hold a publicity clinic 
for all engineering societies and honoraries 
early next fall. A complete review of effective 
promotion methods will be presented so that 
each meeting may be well publicized through- 
out engineering campus. 

In addition, Tech will make axailable a 
complete report on the what, who, and wh\ 
of our engineering societies and honoraries 
for Council to distribute at registration next 
fall. Cooperation will be necessary for this, 
howexer, so that the information can he com- 
piled. 

There are many more activities of im- 
portance to each engineering society that 
Council can promote. A little more emphasis 
along this line will insure more life and ac- 
tivitv on engineering campus. — R. L. H.

THE TECHNOGRAPH 




Varnish paints a grim picture inside an engine. 
Oxidation of motor oil under operating condi- 
tions is largely responsible for varnish accumu- 
lations which result in sticking rings and valves, 
sluggish pistons, loss of power. 

The varnish problem, however, has been all 
but conquered by Standard Oil lubricants. To- 
day our heavy-duty and premium-type oOs 
contain additives — oxidation inhibitors plus 
detergents that keep engines cleaner, keep them 
running longer and enable them to deliver 
more power. 

We learn about these additives and what they 
will do by subjecting our oils to a variety of 



tests. For example, we devised the Indiana 
Stirring Oxidation Test (wliich is performed on 
the machine in the picture) to provide data 
that would help solve the varnish problem. It 
is helping solve that problem. Other tests are 
leading to other improvements. 

Behind all the tests are the men of Standard 
Oil. It is their obligation never to be satisfied 
— to believe that improvements are not only 
possible but necessary. Thus they maintain 
this company's leadership in research, and help 
provide our customers with products that stead- 
ily increase in quality and usefulness.

He uses % of the earth's elements in his cooking 



If you've always thought of glass simply as a 
substance made of sand, soda, and lime, 
we believe this will surprise you: 

Corning scientists, such as the one you 
see here cooking up a batch of experimental 
glass, have actually made glass using 84 of 
the earth's presently known 96 elements. 

Nearly 3000 of these experimental glass 
compositions are turned out every year, as 
Corning scientists search for new and use- 
ful ways to combine nature's elements. 

Already Corning has developed more 
than 50.000 formulas for glass. Just as al- 
loys make metals more useful, these 50,000 



formulas make glass more useful — enlarg- 
ing its applications in untold and sometimes 
surprising ways. 

Corning makes glass so strong that it can 
be used as piping in a steel mill. Corning 
makes glass so soft that it can be melted 
with a match — and glass so resistant to 
thermal shock that it can be heated to a 
cherry red, then plunged into ice water with- 
out its breaking. 

Today, throughout industry, Corning 
means research in glass — research which, 
along with a multitude of other develop- 
ments, has made glass one of today's most 



versatile engineering materials. 

Corning is constantly turning up new kinds 
of glass, new uses for existing ones. So when 
you're out of college, and concerned with 
product or process improvement, it will pay 
you to call on Corning before your plan- 
ning reaches the blueprint stage. Corning

Some of the fibers produced are so 
fine that more than 10 miles of them 
could be wound on an ordinary-si/e 
spool that hohls onl\' 2^0 \ards of com- 
mon cotton thread. 

.Almost irnisible to the naked eye ami 
looking like the threads of a superfine 
spider web, the fibers are drawn from 
slender rods of quartz heated to \er\ 
hiijh temperatures. The delicate threads 
are drawn from the molten ends ot 
the rods and are attached to a revoi\- 
ing wheel, which winds a continuous 
fiber. 

Quart/ fibers produced in the labo- 
ratory are employed in making sensitise 
balances for use in microcheniistry, in 
which minute weight differences must 
be measured. These micro-balances are 
sensitive enough to show weight differ- 
ences less than 1 30,000,()0() of an 
oimce, yet strong enough to hold weights 
a million times greater. The fibers are 
an ideal material for u.se in measuring 
instruments because they are not affect- 
ed by temperature changes and do not 



lose elasticity even when under con- 
tinued strain. 

Operators nuist wear dark glasses 
when fusing ai\<i drawing the fibers,

For Flat Spots 

.Accordnig to the winter issue of "hd- 
ucational Kocus," H;iusch and Loiiib 



has brought the interferometer into 
the worksho|i. The paraplane gages 
can measure the flatness of mechanical 
parts to two millionths of an inch with- 
out special laboratory facilities. 

The optical flat was used for this 
purpose before the n e w paraplane 
gages became available. Optical flats 
are easily scratched, however, and can- 
not be used in recessed surfaces. Para- 
plane gages, so simple that anyone can 
operate them after slight training, both 
replace and extend its function. 




The Paraplane Gage will measure 
flatness to two millionths of an 
inch. (Courtesy of Bausch Lomb).

THE TECHNOGRAPH 



Betatron . . . 

( L'cintinui'il troni page 7) 
w ;l^ M-rifu'il by delicate instruments two 
\cars later, and synthetic particles of 
the supposed "glue" were produced a 
tew years ago by a ciiclotron here in 
the United States. 

The new betatron has fulfilled high 
expectations in its manufacture of large 
quantities of mesons. In the future, 
mesonic study will comprise the greater 
portion of research done by this niacliine. 

//; So/iltiry Co/if i/u iiinil 

The I S months that went into the 
construction of this giant betatron ha\e 
produced a monstrous machine that, of 
gieat necessity, is housed in its own 
little room. This room is a 60-by-65-foot 
space, three stories high, that is par- 
titioned off from the rest of the Physics 
Research Lab by 20-foot deep compacted 
earth and brick walls. The betatron 
itself is about 12 // high, 23 // long, and 
6 ft wide and weighs 400 tons. 

A resume of statistics in comparing 
the present machine with the original 
bab\- "beta" shows the following: 



Exentually, the speeil of the electrons 
approaches that of light, and at a point 
very near this stage, they are diiected 
,iway from the circular path toward a 
tungsten plate. This plate emits a 
stream of X-rays under the constant 
bombardment of the electrons. It is this 
X-ray stream that is the final force 
evolved by the betatron to he directed 
against the desirt'd target. 

.1 f^p/iinti'/iis for Mtsoin 

In the case of mesonic study, the .\- 
i-,iys hit a graphite bar target placed 
between two lead blocks which are in 
turn placed between groups of photo- 
graphic plates. The high-velocity X-rays 
knock apart carbon atoms, whose lib- 
erated mesons then wander through the 
lead and leave a photographic impression 
on the plates. The high speed imparted 
to the mesons enable them to disrupt 
the structures of other atoms in their 
way. These collisions are also recorded 
on the plates. 

What new facts will the present beta- 
tron uncover in nuclear science? That's 
■a h.-ird question to answer; but Profes-

PROBLEM — You ore designing an electric clock for auto- 
mobiles. The clock itself is completed. To set the clock, 
the spindle which turns the hands must be pushed in against 
a spring pressure and then turned — and, of course, when 
the clock is installed, this spindle is bock under the dash- 
board. You want to provide a means for pushing and 
turning the spindle from a point that is easy to get at. 
How would you do it' 

THE SIMPLE ANSWER— Use an S.S.White flexible shaft. 
The illustrations show how one manufacturer does It. Re- 
gardless of where the clock is mounted, the flexible shaft, 
available in any length, makes it possible to put the hand- 
set knob in the most convenient spots. 



This IS |ust one of hun- 
dreds of power drive 
and remote control 
problems to which S.S. 
White flexible shafts 
are the simple answer. 
That's why every engi- 
neer should be familiar 
with the range and 
scope of these "Metal 
Muscles'" for mechani- 
cal bodies.

For many years, ADVERTISEMENTS SUCH AS 
THIS ONE have appeared regularly in leading 
business magazines. Their primary purpose is 
fo build acceptance for Square D Field Engineers, 
practically all of whom come to us from 
leading engineering schools such as yours. 







A sample from every industry served by Square D 
Field Engineers would make quite a load, indeed. 
For these men serve as liaison between Square D 
and every segment of industrial America. Their 
full-time job is working with industries of every 
kind an d size — helping find that "better woy 
to do it." 

Through these Field Engineers, located in more 
than 50 offices in the United States, Canada and 
Mexico, Square D does its three-fold job: Designs 
and builds electrical distribution and control equip- 
ment in pace with present needs — provides sound 
counsel in the selection of the right equipment for 
any given application — anticipates trends and new 
methods and speeds their development. 

If you have a problem in electrical distribution 
or control, call in the nearby Field Engineer. He'll

LOOK FOR THIS RIDGE 




AND 

YOU FIND A REASON 

L 

• There is more than mere identification value in the 
ridge you see on Okonite wires and cables. The ridge is 
proof that the insulation has been folded around the con- 
ductor by the well-known Okonite strip insulating process. 
This method permits inspection at all times during the 
application operation. It assures the perfect centering of 
conductors so important to the avoidance of electrical 
failures. 

The ridge is a permanent mark of an Okonite cable. It is 
still prominent after the final vulcanization in a metal mold 
that insures equal transfer of the heat throughout every 
portion of the insulation. The Okonite Company, Passaic,

Crankshafts stay rigid 
• • . foods stay frigid 

Designers of a compressor for refrigeration plants 
were looking for a way to insure smooth, depend- 
able crankshaft operation. They couldn't risk the 
chance of breakdowns — and the food spoilage that 
might result. 

They stopped possible trouble at the design stage 
— by mounting the crankshafts on Timken" tapered 
roller bearings. Timken bearings take the heavy 
radial, thrust and combination loads, prevent shaft 
wobble, insure trouble-free service with minimum 
maintenance. 



Q: Short on space? 
A: TIMKEN bearings! 

Because Timken bearings have a tapered design, 
they carry loads from all directions. No separate 
thrust devices needed. Also, Timken bearings have 
line contact between rolls and races. This gives 
them greater load capacity, permits use of smaller 
bearings. The space-saving feature is another reason 
why 9 out of 10 bearing applications can be handled 
more efficiently by Timken bearings.

of about _',70() ft., is 77 ft. above the 
general \alle\' floor, and 109 ft. abo\e 
the stream bed. The crest, at ele\ ation 
420 mean (lulf level, is ,i(l ft. wide and 
contains a roadway 22 ft. wide. Ihc 
base width at elevation .i46 mean Ciulf 
level is about 76S ft. The side slopes 
of the dam very from 1 :2.5 to 1 :8. It 



is constructed entirely of impervious 
earth fill, with the e.xception of riprap 
protection stone on the slopes, and is 
also provided with an adequate toe 
drainage system. It is a homogeneous 
structure containing 2, .?()(), 000 cubic 
>ards of earth fill. The VVappapello dam 
was designed h\ the I nited States Kji- 
gineer department and constructeil In 
contract under the direction of the di^- 
trie engineer, .Memphis, Tennessee, ami 
under the supervision of the president, 
.Mississippi River commission and the 
chief of engineers. Total estiniate<l cost 
of the dam and reservoir rims in tlie 
neighborhood of ^^6,775, 000, ot uhicli 
approximately 5";.?, ^27,000 is for the dam 
and appurtenances and approximateh' 
,<•!, 248,000 for the purchase of lands, 
easements, rights-of-way, clearing res- 
er\()ir area and adjustments to roads 
and gas pipe line affected by the con- 
struction of the Wappapello dam. 

The outlet works are located about 
400 ft. from the dam and consist of 
an approach concrete weir, over which 
the waters from the reservoir pass into 
an open paved transition section and 
thence through a concrete D-shaped tun- 
nel conduit about 22 ft. in diameter that 
contains three control gates. After leav- 
ing the control gates, the discharge 
passes into a 724-ft. outlet structure con- 



sisting of a stilling basin and a discharge 
channel. A spillway is available and is 
designed to discharge 227,000 ifs when 
the pool level is 6 ft. below the top of 
the dam. The spillway is provided pure- 
ly for emergency use as the dam was 
o\eitopped after building ami a pmtion 
was washed out.

Six million electric ranges. 
37 million radios. 29 million 
electric clocks. 27 million 
electric refrigerators. 17mil- 
lion electric coffee makers. 
23 million toasters... Thirty 
years ago, they were just a 
sparkle in someone's eye. 
Facts like that should hearten you, when you wonder 
about your future in American industry. The oppor- 
tunity's there — as it was there for Alcoa in the early 
days of electrical transmission. 

Today, nearly half the high-tension lines that feed those 
appliances are made of Alcoa Aluminum. Nearly two 
million miles of ACSR (aluminum cable steel reinforced). 
Although it was light, and corrosion resistant, and con- 



ductive, nobody wanted to make aluminum into cable, 
at the beginning. All right, we said — we'd do it. We 
launched a long research project to produce purer metal, 
and made the basic changes in our reduction processes 
that the research finally indicated. We built a cable- 
testing laboratory long enough to mount whole spans of 
cable, and vibrate them as the wind does, to check 
fatigue strength. This was hard, discouraging work, and 
it took most of the lifetimes of a good many Alcoa people. 
But today aluminum high-lines cross the Great Bear in 
Canada, and funnel Grand Coulee's power into millions 
of homes and factories. We think they stand as a pretty 
good monument to this country's way of doing things, 
through research perseverance, stockholders' courage, 
and employees' hard work. Aluminum Company of 
America, 742D Gulf Building, Pittsburgh 19, Penna.

plus all iu'Cessar\- equipment such as

These footings are reinforced concrete 
set in a compacted earth fill. The siphon 
proper is composed of three electrical h- 
welded steel tubes, each 9 ft. in diam- 
eter :\nd 228 ft. in length with exp.inded 
inlet and outlet transition bells. These 
9-ft. sections are built of .? S in. steel 
and the inlet .ind outlet bells are of 
I 2 in. steel. 

luisiii Disif/ii l^iliiils 

Both the inlet and outlet basins are 
so designed as to utili/e the sheet piling 
cofferdams required in the construction 
of these basins as permanent cells for 
confining the underlying sand founda- 
tion. This feature of design eliminates 
the necessity' for bearing piles in the 
foundation. The inlet basin, immersed at 
.ill times, is not designed to withstand 
uplift: but the masonry is so propor- 
tioned and so reinforced as to be capable 



of suspension without rupture. This sus- 
pension is accomplislu'd b\ fastening the 
masonry to the sheet piluig with dowels. 

'l"he b.i>iii and inlet bells ,ire de- 
signed to eluiini.ate \orte\ action and to 
reduce entrance velocities to a minimum. 
The outlet basin is designed to with- 
stand uplift and is provi\ed with six 
()-in. relief pipes as an .additional safety 
factor. The basin and outlet bells .ire 
so ;nr;uiged to gi\e ,i submerged li\- 
diaulic jump in the basin and to de- 
velop an average velocity of ,>.,'l tt. per 
sec. o\er the sill, thereby pre\i'iiting 
scouring of the outlet channel which 
is riprapped fiu ^(1 ft. 

The siphon is designed for lifts ot 
trom IS to 2<S tt. and for ,a normal 
design flow, using all three pipes, of 
2,6(.)0 rfs with the intake pool at ele\a- 
tion 21,?. 6 (mean (Julf level) and the

(lOO to 1,,S()(I r/,(. for a single pipe and 
from l.SIII) to S, 2(1(1 ,fs. for all three 
pipes. 

In operation the siphon is exhausted 
by the h-in. vacuum pump, and the 
prime may be broken by bleeding air 
into the exhaust line or by opening one 
of the <S-in. breaker valves. In most in- 
stances it is unnecessarv to use the pump 



tor completelv exhausting the siphon 
since the |iipcs become self-priming at 
higher velocities. This action becomes 
effective with the pipe flowing less than 
I .? tiill and with .i difference of onlv 
S or ft. between head and t.iil v.ater 
elevations. Tests conducted up to this 
time indicate that the siphon is oper.at- 
ing in a most efficient manner.

THE DU PONT 

DIGEST 



With the development of Neoprene Type W 

Science Igaiii Outpoints latnre 




Motor mountings, 
among possible usi 



and cable, sponge, gaskets, swim caps are 
Du Font's new Neoprene Type W. 



NEOPRENE — the chloroprene rub- 
ber produced by Du Pont research- 
has long outpointed natural rubber 
on many counts. Because of its greater 
resistance to chemicals, flame, heat, 
sunlight, weathering, oxidation, oils, 
grease and abrasion, it is widely used 
in such products as industrial hose, 
conveyor and transmission belts, in- 
sulated wire and cable, hospital sheet- 
ing, gloves and automotive parts. 

Until recently, however, certain 
natural rubber compositions couldn't 
be beaten when it came to "perma- 
nent set" characteristics. Released 
from the pressure of prolonged de- 
formation, they returned more nearly 
to their original shape. 

This recovery factor is important 
to some manufacturers, particularly 
the people who make gaskets, seals, 



diaphragms, sheet packing, soft rolls 
and vibration-dampening devices. 

NEW PRODUCT NEEDED 

Much as they wanted to use neo- 
prene because of its other superiori- 
ties, they often needed more resist- 
ance to permanent deformation than 
it afforded. So they used natural rub- 
ber, but were never quite satisfied 
with the way it resisted deteriora- 
tion in severe service. 

Du Pont scientists went to work 
to solve the problem. Skilled research 
chemists, physicists, engineers and 
others pooled their efforts. The re- 
sult was a new polymer named Neo- 
prene Type W. 

NEOPRENE TYPE W INTRODUCED 

Chemically, the new neoprene is 
quite similar to previous types. But 






jUyi.

Jackson Laboratory, Deepwater, N. J., one of 
Du Font's laboratories which participated in Ihs 
development of Neoprene Type W. 



its molecular structure has been 
changed so that the mechanical prop- 
erties of its compositions are more 
nearly like those of rubber. With 
Neoprene Type W, it is possible to 
producevibration-dampeningdevices 
that are not only highly resistant to 
oils, heat, grease and sunlight, but 
recover better than rubber from pro- 
longed pressure. 

Neoprene Type W also provides 
the basis for compositions that have 
a low modulus of elasticity — are easy 
to stretch. More attractive colors are 
possible. Soon it may appear in such 
articles as swim caps, where bright 
colors and head comfort are impor- 
tant. The brighter-colored composi- 
tions should also appeal to makers 
of appliance cords, coasters, sink 
mats, stove mats and toys. 

In developing the uses of Neoprene 
Type W, Du Pont is working with 
hundreds of manufacturers and dis- 
tributors. Once again a "partner- 
ship" of big and small businesses will 
cooperate to give Americans the 
benefits of an advance in science.

TWENTY- FIVE CENTS 



6/250,000 in 1949 — another new record 




« 



' I ''HE automobile industry smashed 
records again in 1949 as it produced 
6,250,000 new passenger cars and trucks 
— more than in any other year in history. 
This terrific output of the finest cars ever 
made climaxed a phenomenal rise in 
production that began at the war's end. 
These new cars by the millions are a 
tribute to the American way of life. 
Their production is the result of the de- 
mands of people working under the 
American system of free enterprise, 
which has produced the highest living 
Standard the world has ever known. 



Millions of tons of steel of almost 
every type and form helped America's 
auto makers boost their production so 
amazingly high . . . helped the quality of 
today's automobiles keep pace with the 
quantity. In fact, many new steels have 
been developed just to meet the exacting 
requirements of present-day production. 

In spite of record-breaking production, 
the automobile industry's job is far from 
finished— the average age of the cars on 
America's highways today is 8.4 years. 

Continuing demands for vast quanti- 
ties of steel from the automobile indus- 



try and from countless other sources 
mean a big job for the steel industry in 
coming years . . . mean a promising 
future for men who make steel their 
career. To assure itself management men 
of the highest caliber. United States 
Steel maintains a continuous training 
program that prepares young men with 
suitable backgrounds for places in this 
great industry. 

College engineering courses lay the 
foundation . . . L'nitcd States Steel builds 
a practical knowledge of steelmaking on 
this foundation.

Gas Turbine Locomotive 

Thf nation's tirst gas tuibiiu--electric 
locomotive made its public debut re- 
cently before rail executives assembled 
at the General Electric's Erie, I'a., 
works. _ ,, 

(I. W. Wilson, manager ot ( M. s 
locomotive and car eiiuipment dniMons, 
said the prime objectives of the gas tur- 
bine-electric locomotive designers were 
to develop a prime mover that would : 

1. Hurn low grade fuels, especialK 
coal, economically. 

2. Give higher horsepower output per 
pound and per cubic foot. 

.1. Have greater reliability and lower 
maintenance cost. 

The developmental unit exerts about 
twice as much horse-power at the rails 
as a diesel-electric locomotive of com- 
parable size. It burns low grade bunker 
"C" oil, but Alco-(j.E. spokesmen ex- 
pressed the hope that research may lead 
to a successful means for buriu'ng coal. 

In fuel consumption, the present 
power plant is "much less efficient than 
the diesel engine." 

"Improvement in design and the use 
of better alloys, however, can and will 
increase this basic efficiency." 

Knowledge gained from Cieneral Elec- 
tric's wide experience in the aircraft gas 
turbine field was utilized in the design 
of the power plant. However, the loco- 
motive gas turbine differs from the air- 
craft jet engine in that the gases it pro- 
duces are harnessed within the power 
plant and the resultant power is trans- 
mitted electrically to drive the wheels, 
whereas the aircraft engine provides for- 
ward thrust from the reaction of its 
exhaust stream. 

The locomotive is of single cab con- 
struction with B-B-B-B running gear 



•■Mul an operating station in each end. It 
de\ elops X? horsepower per f o o t of 
length, weighs SOO.OOO pounds and has 
a continuous tractive effort of 68,^00 
pounds at 20^ miles per hour. It is 
S.^ feet, 7j/2 inches long inside of knuck- 
les, 14 feet ZYi inches high over roof 
sheet and 10 feet 7 inches wide over 
hand rails. Geared for 79 in ph. the loco- 
motive carries enough fuel for 12 hours 
of operation at 4,500 horsepower. 

Self-Lubricating Ski 

-Micarta, the same tough plastic used 
in Army helmet liners during the war, 
1U1W promises to enable American *V\ 
champions to set new speed records. 

The Bancroft Racket company is 
making a new self-lubricating ski with 
bottoms made of Micarta — a laminated 
plastic developed and produced by the 
Westinghouse Electric corporation. 

Micarta is as strong as structural 
steel for equal weights of cross-section 
and will add greater strength to the 
natural hickor\ to which it is bonded. 
The plastic is lighter than aluminum 
for equal strength. 

It was the use of Micarta for ship 
propeller shaft bearings that brought 
the ski application to light. Made of 
layers of cloth saturated with a syn- 
thetic resin and pressed under heat, the 
plastic is lubricated by water — which 
means a ski in constant contact with 
snow and moisture becomes self-lubricat- 
ing- 

This means not only more speed, but 
also no necessity for waxing, except m 
very wet snow conditions where snow 
clings. The Micarta-bottomed skis, be- 
cause of their toughness, need not be 
sanded, regrooved, refinished or re- 
lacquered over years of normal service.

Electronic Torch 

.An "elc-ctrumc torch" has been de- 
veloped by scientists of the General 
Electric Company's research laboratory, 
which is hot enough to cut holes in fire- 
brick and to melt tungsten. 

Dr. J. I). Cobine told the Conlerence 
on Gaseous Electronics of combining 
high-frequency radio signals and certain 
gases to produce temperatures consider- 
ably higher than the melting point ot 
tungsten, which is .^.?70 degrees Centi- 
gra.le. 

He emphasized that the electronic 
torch is still at the laboratory stage, and 
that its commercial possibilities have yet 
to be explored. 

Heart of the toich is a tube known a.- 
a "magnetron," which produces radio 
wa\es with the extremely high frequen- 
cy of one billion cycles per second. Lead- 
ing from the tube is an antenna made of 
two short metal cylinders, one within 
the other. If certain gases, among them 
nitrogen and carbon dioxide, are fed 
past the high frequency arc, which forms 
at the end of this antenna the electronic 
jet torch results. 

The molecules of certain gases are 
broken up into atoms by the high-fre- 
quency arc. As these atoms reform into 
molecides on the surfaces placed in the 
torch large amounts of heat are gener- 
ated. The jet itself is not necessarily hot. 

Tracer Photographs 

Scientists stud\ing growth autl deter- 
ioration of body tissue may now locate 
single cells by a process called autora- 
diography. The achievement is expected 
to widen the scope of radioactive tracer 
research in biology and medicine. Ra- 
dioactive tracers enable scientists to 
learn more about the processes of the 
human body. Formerly, however, medi- 
cal researchers were unable to pin down 
tracers to a single cell in a tissue section. 

In an experiment conducted at the 
University of Rochester, a microscopic 
slice from the liver of a rat which had 
been given radioactive carbon was placed 
directly on a photographic plate. Beta 
particles emitted from atoms in the liver 
cells boiuided into the emulsion, de- 
veloped by Kodak Research Labora- 
tories, and exposed tracks of silver bro- 
mide grains. After the plate was de- 
veloped in the usual manner, a pattern 
of black silver grains showed the tracks 
of the beta particles through the emul- 
sion. By examining this pattern under 
a high-power microscope and tracing it 
back to the tissue, it was possible to de- 
termine the cells from which the elec- 
trons started. 

Biologists and medical scientists hope 
to use the new technique to learn the 
effects of organic and inorganic sub- 
stances on individuals to which radio- 
active tracers have been given.

Eiioiiieeriiii! Parade and I M 



The iidwils were niillliif; aiouiid the 
lioiu'vaiil campus — altciriatch looking: 
iioithward aloiij; Huirill A\eiiiic, tlien 
down at till- Hoiieyai'd. The campus 
police were patrolling the area to keep 
the over-anxious out of the street and 
out ot the slimy waters wlicre rile 
much-publicized appearance ot St. Pat- 
rick was to take place. 

Most of the concentrated MttentiOii 
was directed toward the nipple of pipe 
that protruded above the surface of the 
Hone\ard just west of Burrill Avenue 
and behind the Klectrical Engineering 
Building. From this spot the (Jeyser of 
St. Patrick had gushed hourh- up until 
the fateful hour when the HIarne\' Stone 
was stolen from the engineers. Hut now 
the Stone was back in the hands of its 
rightful owners, anil St. Pat was eagerh' 
awaited, since he had promised to be 
among the celebrants on this weekend 
of March 31-April 1. 

The crowds perked up to the sound 
of drums to the north by Illinois Field, 
and in a minute the second regimental 
band, directed by L\man A. Starr, 
turned onto Hurrill Avenue. P'vervone 



took a second look to see that cameras 
were adjusted and then turned again 
toward the oncoming parade. 

A sudden explosion in the Honeyard 
attracted all attention toward the E. E. 
Research Lab. In rapid succession, two 
more explosions followed ; ;uid to the 
west, the green ( ii-\ser of St. I'.itrick 
gushed once more. 

just as the band passed o\er the 
Hone\'ard bridge, another scries of fast 
explosions was heard from the stream 
bed, and a dense cloud of smoke arose. 
When the smoke cleared aw'ay, the 
thousands of celebrants cheered the dra- 
matic appearance of the genial old gent, 
St. Patrick. 

In knee boots and carr\ing a spade 
o\er his shoulder, St. Pat strode up the 
stream and waved to his man\' adnur- 
ers. Dean W. L. E\eritt approached the 
nuirky waters and helped the old gentle- 
man up the bank and then over to St. 
Pat's waiting chariot. 

His chariot was quite appropriate. 
Sitting conspicuously atop the shiny new 
convertible was the beloved Blarne> 
Stone. (In the foin^ fenders rode the

nulit.irx guaid, which was assigned to 
guard the valuable momento. And in 
the driver's .seat was Dick Stone, the 
electrical engineer who, with Jim Wins- 
ton, had heroically recovered the Hlar- 
ne\' Stone from the journalism students. 

St. Pat was dressed as an Irish coun- 
rr\ gentleman (of course!) with a black 
silk hat, black suit, and a brilliant red 
beard and wig. 

After St. Pat fondly cuddled his be- 
loved token, the parade accelerated from 
its /,ero velocity and took a tour toward 
south campus. While cameras clicked 
and the co-eds cooed, the typically en- 
gineering floats displayed the subtle 
humor and ingenuity of the "Boneyard 
bo\s." 

The parade returned to Green Street 
and passed the reviewing stand in front 
of Civil Engineering Hall. There St. 
Pat alighted and admired the work of 
his inspired engineers as the rest of the 
floats passed by. 

On the reviewing stand were the 
official parade judges: Bob F'itzgibbon, 
editor of the Il/ini; Larry Siegel, editor 
of Shaft: and Chuck Flynn, publicity 
supervisor of the Athletic As.sociation. 

Their decision regarding the floats 
entered b\' members of Engineering 
Council listed the following as the top 
three : 

IAS presented the most beautiful 
float — partly because of the beautiful 
blonde "test model" that rode atop the 
mock-up wind tunnel. Lacking an aero 
engineer with sufficient wind, they had 
a hand bellows supplying the breeze. 
The pilot in a miniature airplane at the 
rear of the float tossed paper airplanes 
and flying saucers to the crowds. Work- 
ing under Cliff Felt, Byron Gabbert 
was in charge of this masterpiece. 

The chem engineers put a bit of their 
new building on wheels and presented 
the U. of 1. chenu'cal plant — replete 
with smoke, slime, ,ind sm . . . per- 
fLime. 

With four ag engineers as the team 
of horses, AS.AE presented a contrast of 
fariuing methods before and after the 
imasion of engineering into the realm 
of agriculture. 

Tops among the floats in the "non- 
member of Engineering Council " com- 
petition were the engineering physics 
students, !VIu-San, and Chi Epsilon.

Story of the Blarney Stone 



With a bit in(iic taiitarc than Moses 
l\.i(l, I was (lisi()\ iTfil among the sliiiu 
nislics of tlu' l?<)nc\aiil at 4 p. m. Feb- 
ruary 10, l''^0. This ;;lori()iis bejiiii- 
ning of ni\ well publici/ed career was 
described in the March 'I'kIi. 

For about a month after m\ crashing; 
tlie news I was placed in solitary con- 
tinement — not for misbehavior, but for 
my own securit>. The cold walls of 
the safe in C. K. H. seemed to feel sorr\ 
for me — such a prodigy without aii\ 
recognition — but their compassion \\as 
little comfort to my heav\- heart. 

Finally on March 13 I was given my 
rightful recognition by my protectors 
and my public. Along with some pic- 
tures of my discovery and a bit of blar- 
ney about coming events, I was placed 
on a beautiful kelly green ( I love that 
color!) pillow in the Illini Union Hook- 
store window. There I winked at all the 
pas.sersby and reminded them of the 
green gevser that sprinkled iiourly from 
what had been m\ resting place for cen- 
turies. 

Incidentally, 1 don't believe everyone 
understood the purpose of St. Pat's (ley- 
ser. Being the first engineer upon this 
earth, St. I'at had an interest in sani- 
tary engineering as well as some of the 
more prominent fields. My inscription, 
"Flush Ye Honevard," attested to this 



acti\ify of St. Patrick. 'Fwchc cen- 
turies ago he started tlu- campaign to 
clean up the Honevard. As nothing ha<l 
been done about the bilge and the local 
citizens were against a recent proposal 
to clean it up, St. Pat himself brought 
forth his geyser of disinfectant that not 
ordy turned the nuirky mess into an 
enier.ald green, hut piiritied the putrid 
waters as well. 

When l''rid,-i\, March 17, came 
around 1 was particui.arly happ\ , as this 
was the birthdav of the one responsible 
for m\ inception. I didn't ha\e the 
opportunity to celebrate like the rest 
who worship my patron saint, hut I 
ne\ertheless revelled in the ghiry of 
da\s gone by anil those to come. 

About 7 o'clock that e\ening 1 was 
rudel\ shaken from my dreams b\ 
two rough hands th.at lifted me from 
my comfortable resting place. 'Fhe\ 
smoothed out my pillow to leave it 
looking pretty, but I was treated like 
an ordinary rock from the L'niversit\ 
rock gardens on .south campus. These 
two unfamiliar faces that disturbed my 
placid thoughts were brutal and utter- 
ly disrespectful of m\ age and impor- 
tance. 

The next Tuesday morning, :ifter en- 
gineers had been worrying about ni\ 
whereabouts (and rightly they should 



h;i\e) there .appeared in '/'//( Diiily 
llliiii a stor\ about my sad e\perience 
as a displaced person. 

File mini authorit\. ;i|iparentl\ 
knowing more than I did about the 
awful act said that "the kidnaping of 
the stone was accomplished in full \iew 
of hundreds of pas.sersby. The prank- 
sters, or thie\es, persuaded the janitor 
to remove the 'bit of auld Erin' from 
the window of the bookstore by repre- 
senting themselves as engineers sent to 
get it for a St. Pat's partN." 

Fhe authority went on to sa\ that 
some persons were accusing law students 
or high school students here for the bas- 
ketball tournament that weekend. He 
also inferred that engineers might ha\c 
stolen it themselves in an effort to 
arouse a bit of interest and publicitv. 
True, I am happy in the arms of an 
engineer, but there is no engineer alive 
who would use a sacred token like me 
for such a base purpose as mere pub- 
licity. 

Just before Engineering Council 
meeting, Thursday, March 23, Dick 
M\ers, Council president, received a 
scroll from his patron saint and my god- 
father. The browned and worn parch- 
ment contained this ominous warning 
from St. Pat:

I SEE activities. Right: The A.S.A.E. won third place with their float displaying modern and ancient

THE TECHNOGRAPH 




One of the shamrocks that so 
mysteriously appeared on four of 
the engineering buildings one 
bright Saturday morning. (Photo 
by John Huber.) 

"Know \f, () i'rt-M'dcnt Myers and ye 
Council 

That I be displeased \vi' ye 

I'"r allowiii' th' stealin' o' me belo\e<l 
Hhirney Stone! 

V'r thi> act, I \va\e me shillelaf^h slide

An' hereby decree that th' (ieyser 

Will appear unto \e no more 

I ntil me stone be brought back. 

Know ye that th' stealers o' me stone 

He certain ones among th' law or jour- 
nalism students. 

If ye recover me Blarney Stone, 

1 will appear before ye 

1 ri a right ni\sterious cloud o' smoke. 

An' if ye do not recover it. 

Woe betide th' College o' Engineering, 

I'"r me wrath will know no bounds! 

An' I will haunt this campus wi' me 
Shamrocks 

liitil \e do get me stone back! 

-Mark ye well my words! 

Signed: St. I'at." 

The world was soon to learn, that 
as well as having infinite mercy, m\ in- 
ceptor can .show infinite wrath. 

St. Pat just barely began his haunt 
of the campus with a Shamrock Scare, 
when those responsible for my displace- 
ment came forth with an admission of 
guilt. The four maiji engineering build- 
ings along Green Street blossomed 
forth with beautiful green 8-foot sham- 
rocks on the Saturday morning of 
March 25. They caused considerable ex- 
citement among engineering and south- 
camp\is students, as well as most of the 



l'ni\ersity police force and the Physi- 
cal plant. (The latter group, which 
supplies the University with power and 
v.ii-lds plenty itself, had the shamrocks 
removed that afternoon.) 

Hut the big accomplishment of the 
Shamrocks was to scare the officers of 
Sigma Delta Chi. "professional" jour- 
nalistic fraternit\', into admitting their 
possession of the beloved token of St. 
Pat. However, in a guilty attempt at 
reconciliation and "to show that jour- 
nalists are tolerant of the bigoted atti- 
tudes of other groups on campus . . . " 
SDX offered to return me to my right- 
ful owners at St. Pat's Ball if certain 
humiliating concessions were made. 

The following Monday evening at a 
group meeting of all engineers working 
on 1 SEE and St. Pat's Hall commit- 
tees, the chairman of the former com- 
mittee proposed a compromise to SDX 
in order to regain my presence for the 
St. Pat's parade the following after- 
noon. Arrangements w-ere made for a 
tug-of-war between 20 journalists and 
2<l engineers with me in the middle — 
the dividing line and finish line for the 
tussle. The winning team (and there's 
no doubt who that would have been ) 
was to carr\ me off triumphanth to 
their halls of learning on north cam- 
pus. 

Thursda\-, the da\- when the tug-of- 
war was to be pulled off, the /////;/ 
Iirinted the following admission: "Hob 
Roderick, president of Sigma Delta Chi, 
professional journalism fraternity, ad- 
mitted that the stone is no longer in 
SDX's po.sse.ssion. A member of SDX, 



Hill .Muster, had been carrying the 
stone in the luggage compartment of his 
car. Hut it wasn't there when he looked 
yesterday afternoon. " 

The journalists were even a bit more 
lax in guarding me than were the en- 
gineers. Two engineers (and Il/ini pho- 
tographers), Dick Stone and Jim Wins- 
ton, drove to Chicago Tuesday after- 
noon, March 28, to get me from Mrs. 
Hill Muster who, they thought, had me 
in a bureau drawer. 

After Mrs. Muster said that Hill had 
me confined to a grip in the luggage 
compartment of his car, Dick and Jim 
sped back to Chambana to rescue me 
from my claustrophobia. They picked up 
Muster's car keys while he dreamed lui- 
suspectingly, slipped me out of his car, 
and retiu'ned the ke\s to his bedchani- 
ber. 

After a rousing phone call to Dean 
W. L. Everitt, my heroes drove over to 
his Pennsylvania Avenue residence to 
present him with me. The Dean was as 
happy as I was, so we four got a pic- 
ture taken in front of the grandfather's 
clock at 3 :08 a. m. 

Dean Everitt, Dick Stone, Jim Wins- 
ton, and I then returned to what was 
left of a happ\' night of slumber — a*ter 
I was carefully placed in the house 
safe. And happih there I remained un- 
til that glorious Friday afternoon pa- 
rade and then the Saturday evening 
when I was carried to my pinnacle at 
St. Pat's Ball to bask in the radiation 
of the green spotlights and enjoy the 
fond admiration and awe of ni\ lo\al 
dancing audience. 




Dean Everitt happily accepts the Blarney Stone from Jim Winston and 
Dick Stone who liberated it after its capture by south campus individuals.

ST. PAT'S BALL 



Alrci' tlncc siiincH'riK'kini: \vcfk> ol

the ni^lu i)t April 1. 

F()lli)U'iiig wfU - cooidiiiati'il plans, 
(luois closcil on a successful I SEI" at 
():()() p. ni. and dc-slidcrulcd engineers 
and their tlates took off for the annual 
St. Pat's Hall that was held that night 
in Muff ('ivnuiasiuui from ''lOO to 
1J:(M) p. ni. 

Hud Roilerick and orchestra set the 
pace with aniazinglv' fine dance music 
and plenty of Irish waltzes thrown in 
for good measure. Vocalist Jene Fer- 
rell, who made her singing debut with 
Roderick on this night gave song ren- 
ditions that soothed the jangled nerves 
and aching backs of many an engineer 
who had ilriven nails and hauled ma- 
chinery during the last few frantic days 
of prepararion foi- the Kxhibit. 

The legendary Hlarney Stone that 
had set the ke\'note for the spirit of the 
entire weekend, reposed on green velvet 
on a large platform in the middle of 
the dance floor. Behind the bandstand 
at the south end of the gyni, a 25-foot 
shamrock adorned with a large slide 
rule hung against a white back-drop. 
The ceiling of Huff Gym was "low- 
ered" an impressionable 30 feet by a 
false ceiling of green and white crepe 
paper. Finishing touches were seven 
sni;illcr S-foot shamrocks hung from the 
halconv. 

These balcony shamrocks were the 
center of some speculation during the 
e\ening. A general (though unspoken) 
consensus of opinion was that these were 
the famed shamrocks that had made 
mysterious appearances on the fronts of 
the four main engineering buildings 
along Green Street the pre\inus Satur- 
day moriu'ng during the Shamrock 
Scare. 

Couples who tire<l of d.ancing dining 
the evening were interested spectators 
of some of the 1 SFF. displays that had 
been brought down to the (]\ni after 
6:00 p. m. One of the most popular 
participation exhibits was the K. E.s' 
"Kiss-o-meter," that gave shcnt but brit- 
tle ratings of an individual's mastery of 
the art of kissing, with such comments 
as "cold," "luke-warm," and "red-hot." 
For the thirsty, the "Coke-tail" bar op- 



t-raffd full bla^t in the lower regions ol 
the g\ni. 

Internussion at 10:30 p. m. began 
with a short introductioji of Hill Hier- 
b:uim, ( b\ Hill Hierbaum), who car- 
lied the ball as .Master of Ceremonies. 
Hill, now well-known for his M. C. 
wink :it three successive St. Pat's Halls, 
next brought forth the Theta Chi octet 
tor harmoiu/ing on a few Irish bal- 
lads. 

Hill then turned :ittention toward the 
]51arney Stone where St. Pat, the lo\al 
patron saint of the engineers, now ap- 
peared to dub his faithful eleven as 
Knights of the Order of St. Patrick. 
( Rumor has it in higher engineering 
circles that the patron saint was en- 
acted b\- Prof. John S. Crandell of the 
Ci\il Engineering Department.) 

The Knights were outstanding sen- 
iors who had been selected by Engineer- 
ing Council from 200 nominations on 
a basis of scholarship and outstanding 
work in engineering activities. Those 
receiving this honor were Hank Kahn, 
Hruce Everitt, Al Benson, Gene Han- 
kins, Errol Rodda, Dick Myers, Ra\ 
Hauser, Betty Lou Bailey, Maurice 
Cobb, (lerald Marks, ;uhI Keith Good- 
win. 

As his (or her) name was called off, 
each prospecti\e Knight came forward, 
kneeled before St. Pat, was knighted, 
kissed the Blarne\ Stone as a proof of 
lasting devotion, and was then gi\en 
a small gold shamrock charm engraved 
with the words, "Knight of St. Pat, 



I'JSO." (Juite a lew grimaces were seen 
on the faces of the Kiu'ghts as the\' 
kissed the Stone, lor rumor declared 
that shreds of slime aiul filth still coat- 
ed the Stone, that had not been washed 
since its removal from the bed of the 
Boneyard. St. Pat pronounced any idea 
of washing the Blarney Stone a sac- 
rilege, since the slime on the Stone's 
surface only enhanced the Stone's al- 
read\' savor\' glory. 

Dick Myers, president of Engineer- 
ing Council next presented the aw^ards 
to the I SEE Exhibit and Parade win- 
ners. Copping honors for their very 
well-planned illumination show, lES 
took the 1 SEE Exhibit trophy. IAS won 
the P:nade trophy for the best float en- 
tered b\- an Engineering Council mem- 
ber societ), and the Physics Depart- 
ment won in the non-Engineering Coun- 
cil competition. The Parade awards 
were especially-designed engineering tro- 
phies planned and executed under the 
direction of (jeorge Vriend. 

Dean W. L. Everitt woiuid up the 
intermission with a short speech of 
thanks to the committee of I SEE and 
to Dick Stone and Jim Winston, res- 
cuers of the Blarney Stone after its 
theft b\ the journ:dists. 

So another St. Pat's Ball came to a 
close. C^nly one sad note marred the 
evening. The unguarded Blarney Stone 
again disappeared — only this time, it 
will be for safe-keeping until another 
St. Pat's celebration rolls around in 
1951.

.Mr. Ogg, the educational director of 
the Diesel Engines Manufacturing As- 
sociation, spoke on "How Patents Af- 
fect the Engineer" at the April 18 meet- 
ing of the SAE. He stated that the aim 
ol the original patent law was to fur- 
nish an incentive and reward to in- 
\entors by giving them a 17-year mo- 
nopoly on their invention. Mr. Ogg told 
how modern industry handles patents 
by drawing up a patent contract. He 
pointeii out that this philosophy is di- 
rectly opposite to that of the original 
patent law. In explaining the actual 
procedure of obtaining a patent, he told 
of the \alue of a consulting attorne\ 
and of constantl\ keeping your applica- 
tions on file.

To improve the accuracy of testing 
Bell telephone switching equipment and 
to speed up tests during manufacture, 
Western Electric engineers designed 
and built a unique test set — known as 
the Tape-O-Matic — which has a paper 
tape "brain." 

Controlled by a narrow paper tape, 
punched with coded information, the 
machine aiitoiiiatically performs compli- 
cated series of tests. If there is a fault in 
the equipment under test, the Tape-O-

Matic stops, rings a bell and indicates 
the source of trouble on a lighted panel. 

Some 1200 different tapes, varying in 
length from one to thirty feet, are used 
for testing various assemblies. Formerly 
an operator, in testing an average size 
assembly, had to make 41 individual 
connections. With the Tape-O-Matic, 
one multiple plug connection does the 
job. And 2S preliminary tests, 81 lamp 
observations and 71 key operations are 
replaced by one tape insertion and the 
push of a button. 

The Tape-O-Matic can cut testing 
time as much as SO "o — practically elimi- 
nates the possibility of human error — 
and helps to assure equipment of highest 
quality. It is a good example of the 
ingenuity, skill and thor-

Two types of courses are offered b\ the 
Agriculture Engineering Department: 
service courses are offered as practical 
training for agriculture .students, and 
technical courses are offered for engi-

gineer for the University of Illinois for 
thirteen years, he has an intimate knowl- 
edge of nearly every soil conservation 
and drainage project in the state. His 
classes are greatly enhanced by his abil-

In January of l^Sl, Professor Hay

For years, working toward the ulti- 
mate in sound reproduction, scientists 
ha\e sought for living presence — the 
illusion that a musician or speaker is 
talking, singing, playing in your home. 
Now, with RCA's Duo-Cone loud- 
speaker, the goal is achicxcd. Two sound- 
cones in acoustical alignment reproduce 
sound without distortion, and gi\e you 
every tonal %alue from a frequency of 30 
on to 15,000 cycles. It is in the area above 
a frequency of 4,000— seldom touched 
by conventional speakers— that most of 



the all-important "overtones" lie. RCA's 
Duo-Cone loudspeaker reproduces e\'ery 
o\ertone — to the very peak of a violin's 
range— and faithfully gives you the deep 
low notes of a bass drum! 

In addition, ihe RCA Duo-Cone loud- 
speaker's wide angle of sound pervades every 
comer of a room without sharply directed 
blast or blare. Its response to tones of every 
frequency is smooth, flowing, and even.

and Richard Hofmeisfer, M.E. '53 

Due to the loi'ation ot the X.i\ \ I'ici

section ot the Middle West, students 
attciulinp; the Pier lia\e the opportunity 
to observe every t\|ie nt iiidustr\ in op- 
eration ranjiinj; troni t()un<lncs to as- 
senibh plants, troni start to tinisii. 

In tile time it would taice to luar a 
lecture, students can visit a factor) and 
observe the actual methods, and .see the 
work being turned out. These opportu- 
nities have not been wasted by the Pier 
engineers. They have taken advantage 
ot these opportunities and e.xplored them 
to the fullest extent. Classes in materials 
casting have visited pattern shops and 
foundry suppliers to see I'.ow the work 
is done, giving them a clear pictme of 
engineering "know-how." Dining the 
Christmas vacation and between semes- 
ters, the student chapter of the Ameri- 
can Society of Mechanical Engineers 
at Navy Pier spnnsoi'ed a series of eight 
toin's of [ilants including foundries, a 



steel mill, an assemhl\ plant, machine 
shops, and a gas pLant. 

.A txpieal plant of those visited is the 
Pettibone Midliken Corporation. This 
iirgani/ation falls \\\ the medium si/e 
classification ot industry, having a par- 
ent companv' and several subsidiaries. 
Here the entire process of manufacture 
can be viewed at a glance. The ilesign- 
ing, fabrication, machining, assembK, 
and testing are completeh' handled by 
this one comp,ui\. A brief description 
of the tour through the plant will illus- 
trate this principle. 

The trip through the Pettibone Mul- 
liken Corporation included the Petti- 
bone Mulliken plant, the Beardsley and 
Piper Division plant, which is a sub- 
sidiary of Pettibone Mulliken, ami the 
engineering building. After a brief 
breakfast, the tourists, lumibering about 
T.i engineers from the Pier and from 
the L'rbana campus and eight instruc- 
tors v.ere divided into five groups. Each 
group, consisting of about ten students 
and several instructors, were provided 
with a guide who was a member of the 
management. 

Heginning in the forge shop, the 




group obseived one ot the important 
mctho<ls of fabrication. The huge drop 
hammers provided an unusual and awe- 
some sight for the xisitois. From here, 
the to\ir moved to the foundiv where 
the casting pioeess was reviewed. .Mold- 
ing, core-making, melting in electric 
lurnaces, shakeout, and cleaning were 
seen in operation. One of the most in- 
teresting and unusual machines was the 
sandslinger which was developed and is 
manufactured by Heardsley and Piper. 
This machine slings sand into ;i mold 
at the rate of 1600 pounds per minute, 
giving a firmlv rammed mold in one 
operation. 

The machine shop was next in line to 
be visited. Here the m.ichiiiing of m.iii-

ducer, was seen. (Jang drills in opera- 
tion sparked the interest of the engi- 
neers, as did the grinding of manganese 
steel frogs. Each rail frog is constructed 
to different specifications and therefore 
requires a different pattern. As most of 
these frogs are about fourteen feet in 
length, each job requires a great deal of 
pattern work. 

At noon, the visitors were treated to 
a lunch by the management. Following 
the meal, photographs of the various 
groups were taken by the editor of 5(7- 
/('/■ Methods, a company magazine 
which is widelv' distributed throughout 
the foundrv industry. 

During the afternoon the groups 
toured the Heardsley and Piper Divi- 
sion of the corporation, makers of foun- 
dry equipment such as the Spcedmidlor, 
Sandslinger, and Screenarator. Opera- 
tions in the machining, a.ssembly, and 
painting of these devices were watched 
at this plant. For the benefit of the 
visitors, much of this equipment was 
explained and demonstrated. It could 
be seen that many variations in the 
sizes and tv|ies of a particular device 
are made to suit all possible needs. An 
example of this is the midler which 
ranges from a small wheelbarrow v a- 
iiet\ called the Miilbaro to the large 
Speedmuller which is several feet in 
diameter. 

Following the completion of the tour, 
a question and answer session was held.

Woyne King, "The Walti King", is ont' of America's 
most popular entertainers. His weekly Standard Oil 



television show is a ildij^ht to see and hear — and it 
makes him one of Standard Oil's best salesmen. 



More than sweet music 

comes from this horn 



Let's assume that Standard Oil researchers and 
engineers have fully developed and tested a new, 
outstandingly improved petroleum product. Let's 
assume that the product has been made and dis- 
tributed to Standard Oil dealer stations. 

What happens then? 

That's where Wayne King and all our other sales- 
men take over. They inform the public about this 
new product. And when the public buys, there's 
work for people to do all down the line: work for the 
service station man, for the refiner, the pipeline 
man, the driller. The more we sell, the more people 



we need to make new products. Our present em- 
ployees become more secure in their jobs, and new 
jobs open up. 

Good salesmanship, you see, is vital to all of us. 
But good salesmen must have good products to sell 
— and that is why research and product engineer- 
ing, as carried on at Standard Oil and other pro- 
gressive companies, is also vital. 

Good products plus good salesmanship are an 
unbeatable combination that helps make our coun- 
try great and the American standard of living the

While liberal arts students now out- 
number engineering students at Illinois, 
this is one of the few schools where the 
engineers got there first, ami the liberal 
artists came in later. 

When the I . of I. i;ot its start in 
liSbiS, it uas know II as llluiois Industrial 
University, and existed ,solely for the 
purpose of producing educated engineers 
and farmers. As such, it was one of the 
first engineering colleges in the country 
and was looked upon with suspicion b\ 
the traditional classical educators. 

That these classical scholars ha<l their 
fingers in Illinois Industrial University 
is shown b\' the entrance requirements 
for 1S68-1869: the stLident had to know 
natural philo.sophy, algebra, geometr\, 
Latin grammar, Caesar, Cicero, X'^irgil's 
(leorgics and the Aeneid. 

Life for the student was rough in 
those days. L'ni\ersity housing consisted 
of a dormitory which also contained all 
of the school's laboratoi ies. A ten-b\ 
fourteen-foot double room in the dorm 
cost only foui- dollars a semester, but 
\ou didn't get much for your four bucks. 
The rooms were unfurnished, and the 
occupants had to provide their own 
stove and beds. The 1868-1869 cata- 
logue stated, "It is recommended for 
health's sake that the occupants sleep in 
separate beds. " 

The student was required to work at 
least an hour a day, usually on the Uni- 
versity buildings that were under con- 
struction. For this work he was paid 
the princeh' sum of eight cents an hour. 

The mechamcal engineers really had 
a rough obi time of it in the beginning. 
When the students of Mechanical 
Science and Art in the Polytechnic De- 
partment (as thc\ were then called) 
went to their first classes, thev disco\- 
ered that the\ weie pioxided with a 
lathe — but the power to run the lathe 
was in the form of a set of castings for 
a lO-hp steam engine. So as a shop pro- 
ject they turned out the castings, ro- 
tating the lathe by hand. 

For man)' years a thesis was required 
of cver\ engineering graduate. In addi- 



tion, the engineers weie reipiired to 
write \acation journals e\ery summer. 
These were supposed to include de- 
scription, with dimensioned drawings, of 
(■\er\' interesting machine the engineer 
s.iw. So \ou think \()u'\e got troubles?

In the days when the U. S. Navy con- 
sisted of a frigate and two flat-bottomed 
rowboats, our naval uniforms were 
amazingly ornate things, with gold 
piping on the trousers, gold epaulettes, 
and plumed hats. So it wasn't surprising 
that a British diplomat at a parr\ 
should mistake an Amcrical naval 
officer for a doorman and say to him, 
"Call me a cab." The seaman smiled at 
the I'nglishman and said, "^ ou're a

Perha|)s you are curious about \v hat 
goes on at those ph\sics colloquiums 
with the incomprehensible titles. A re- 
port<'r for this column was, and satisfied 
his curiosity by attending one entitled, 
"Angular Correlation in Successi\-e Nu- 
clear Radiations." It turned out to be a 
pleasant, informal affair. 

Festivities began at 4:13 in room 21 J 
in the Ph\sics building. People were met 
at the door by a charming lady plusicist 



who served coffee and cakes. Almost 
e\er\ member of the physics staff and 
most of the graduate students were 
there, standing in little groups and 
talking. (loing from group to group 
our reporter heard conversations about 
university housing, flushing the Bone- 
yard, California politics, and women. 

Later, after everyone had gone down 
to room 100, the full professors sat in 
the front row, associate professors were 
mosth' in the second row, and ,so on. All 
conversation stopped as if a vahe had 
been turned when Dr. (ioldhaber of 
the Physics department got up and stood 
in front of the room. 

Dr. (loldhaber introduced the speak- 
er. Professor D. L. Falkoff of Notre 
Dame. Mr. Falkoff began his talk by 
sa\ing, "I will spend the first half hour 
proving why angular correlation should 
not exist." And this he proceeded to 
do, speaking rapidly and with decision. 
When he had finished his proof, he said, 
"Since angular correlation does exist, 
there is apparently a paradox." He wait- 
ed a moment, and added "But let me 
break the suspense." So he explained the 
paradox — to those who could under- 
stand him. 

During the explanation he had some 
slides to show. The room was darkened 
and an a.ssistant showed the first slide. 
It was upside-down. The assistant took 
it out, fiddled with it, and put it in 
again. It appeared upside-down and 
backwards. The assistant looked be- 
wildered. Dr. Loomis, head of the 
physics department, strode up to the 
projector and in quick motion took the 
slidi- from the assistant and shoved it 
into the machine. It appeared on the 
screen in perfect order. Dr. Loomis 
smiled modestly as everybody applauded. 

After Dr. Falkoff had finished his 
talk, he stood up against a barrage of 
questions. When everyone's curiosity 
was satisfied, Dr. Goldhaber suggested 
that everybody go upstairs for more 
coffee. His suggestion was followed 
with glee.

means more passengers for the railroads so that they can keep fares down and still add more comfort to long trips." 





"Railroad comfort comes from many 
things, son. Smooth-fitting parts are 
important. Parts like Diesel engine 
crankshafts, pistons and wheels. That's 
why so many railroad shops use 
Norton grinders and Ahniduni grind- 
ing wheels to make parts smooth. 






"Take those side rods on steam loco- 
motives. They get farther over on the 
smooth side thanks to Norton internal 
grinding wheels. And parts arc fin- 
ished so accurately with Norton 
quality controlled wheels that they 
last for thousands of miles, Paul. 




"Getting back to comfort . . . modern 
trains travel over 60 miles an hour. 
So, they need smooth rail joints. 
Those joints are welded for safety. 
Then, they're ground smooth and 
slotted with Norton grinding and cut- 




" Hundreds of other parts 
of modern railroad trains and tracks 
also get a lift from the sure touch of 
Norton Products. So does just about 
any other product you can name. 
That's why I'm not boasting when 1 
say that Norton makes better products 
to make other products better."

Came OuUa l/fo44A. SUelL ! 



In a spcfcli class iccriitly. two assignnu-iits 
well' presented by two engineering stiuieiits. 
\\\ coincidence, the speeches took opposite 
\ lews on an unspoken but well-practiced code 
i)t the campus this side of (ireen street. 

One of these had as its general topic, "Win 
engineering students are entitled to remain 
.iloof from outside activities." The author's 
explanations centered aroimd the old assump- 
tion that engineering, as one of the more 
difficult college courses, required a great 
deal moie stud\ and preparation than other 
curricula. 

The other speech set forth reasons why en- 
gineers, in particular, should be active in cam- 
pus affairs. The author of this contention 
was not only an honor student in engineer- 
ing, but was aLso one of the top campus lead- 
ers in extra-curricular activities. 

Isn't it about time that we engineers stop 
hiding behind the college's skirts with the 
lame excuse: "Engineering is too hard; we 
don't have time for anything else"? No en- 
gineering curriculum is so hard that it pro- 
hibits participation i[i activities. 

Isn't if about time that we admit the truth 
i[i recent Dai/y Illini editorials and columns 
criticizing engineers for lack of interest in 
campus affairs outsi<le the classroom? 

"Lack of interest " is an ugh little phrase, 
and one to which we of the dignified engi- 
neering profession are loathe to admit our 
guilt. 

One of the very truthful but painful facts 
that recently stood in the way of obtaining 
Kngineering Council representation in the 
Student Senate w-as the rotten example of 
this "lack of interest" in which a requested 



voting booth was installed on engineering 
campus during campus election da\' last >ear. 
Oi about 3,000 engineering students that 
passed b\ its location on BurriU A\enue, 
only 60 bothered to cast a ballot! This is one 
incident that can't be passed off with the 
"gotta study" routine, since it requires only 
two minutes to \ ote. 

However, the picture is not so murky as 
the first part of this editorial might have it 
seem. Engineering students can and have daiir 
excellent jobs in combining heavy academic 
studies and outside activities. One shining ex- 
ample of this was the recent I SEE and En- 
gineering Weekend. A conservative estimate 
was made that at least 500 engineers devoted 
time to their individual society displays, floats 
for the parade, or general committee work 
iluring this period. We not only surprised 
ourselves and the faculty with the interest 
■ind hard work put into this project, but we 
also proved that only engineering ingenuitv" 
could have produced the fanfare and "Blar- 
ney" that certainh' woke up the campus to 
the fact that "St Pat was an Engineer." 

Of what good are such campus activities? 
Their actual value to the individual far ex- 
ceeds the one purpose of showing a live en- 
gineering interest in campus activities ; the 
reward will lie in the friendships, technical 
contacts, and associations with fellow engi- 
neers that will be worth more than gold in 
the years to come. 

What we do here in college will be the 
beginning of our professional society activi- 
ties which manv' of us will carry on through- 
out our lives. What we do here in college 
will also be the beginning of a broad outlook 
on the greatest of all professions — the P'ngi- 
necring of Life. — C. W, M.

Electricity is so much a part of our lives today 
that a new, lower-cost way of carrying it is 
important to everyone. 

Alcoa E.G.* Aluminum conductor for insu- 
lated electric wire and cable is revising old 
ideas of cable costs. In large size cables, alumi- 
num conductors weigh only one-half as much as 
copper of equivalent current carrying capacity, 
are therefore lower in cost and easier to handle. 
Cost and weight savings are worthwhile in all 
sizes down to No. 6.

Leading manufacturers of insulated wire and 
cable are making their products available now 
with conductors of Alcoa E.G. Aluminum. Sup-

The TiJi's business maiiat;ei for the 
next year will be Hill Anderson who, 
ironically enough, joined the staff three 
\cars ago because of his interest in en- 
gineering writing. He was assigned to 
the business staff because, as Bill puts 
it, "they had enough peasants on the 
editorial staff." His first year was spent 
performing general duties, but the next 
year found him promoted to the depart- 
ment of national advertising. This 
past ve.ar Bill has been assistant busi- 
ne>s manager in ch.arge of national ad- 
\ertising. 

If we delve into Hill's personal his- 
tory we find that he and a twin-sister 
were born in Jersey City, New Jersey; 
hut he has spent most of his life in 
Neu Rochelle, New York. He graduat- 
ed hnin New Rochelle High School 
ill lime, 1940, with a major in business. 
Five of the next eight years found 
him working in the field of heating, 
\entilating, and air-conditioning as a 
sheet metal mechanic. During the other 
three years he was superintendent of an 
aircraft sheet metal department at a 
sub-depot of the U. S. Army Air Force 
overseas. 




WILLIAM A. ANDERSON 

liill then enrolled in the Iniveisity

His mam interest lies in the perfection 
lit air conditioning systems for small 
homes. After graduation in '^1 he plans 
to become established with a corpora- 
tion concerned with heating, ventilating, 
and air conditioning as engineer and 
manager. His operating territory will 
he Westchester County, New York.

PROBLEM — You are designing a machine which 
includes a number of electrical accessories any one 
of which can be turned on by means of a rotary 
switch. For reasons of assembly and wiring this 
switch has to be centrally located inside the machine. 
Your problem is to provide a means of operating the 
switch from a convenient outside point. How would 
you do it? 

THE SIMPLE ANSWER — Use an S.S.White re- 
mote control type flexible shaft to connect the switch 
to its control knob. This arrangement gives you com- 
plete freedom in placing both the switch and the 
control knob anywhere you want them. That's the 
way one manufacturer does it in the view below of 
part of the equipnic;.? whh ccv>3r removed. 




This is just one of hundreds of remote control and power 
drive problems to which S.S.White flexible shafts provide 
a simple answer. That's why every engineer should be 
familiar with these "Metal Muscles'" for mechanical bodies.

Du Pont scientists pursue their studies 
from Buffalo, N. Y., to Orange, Texas 




THE DU PONT COMPANY is a large 
company. Its many manufactur- 
ing plants are now located from 
Maine to California. Likewise, the 
Company's research activities arc 
spread over a wide area. From the 
Founder's informal scientific experi- 
ments on the Brandywine have 
sprung 42 research and development 
laboratories in ten states. 

Each manufacturing department* 
has its own research director and 
maintains facilities for studies in its 
h'pecialized fields. Thus, research hav- 
ing to do with dyes, neoprene and 
fine chemicals is centered at Deep- 
water, N. J.; research on cellophane 
and other transparent wrapping films 
at Buffalo, N. Y.; research on viscose 
rayon at Richmond, Va.; and re- 
search on coated and impregnated 
fabrics at Newburgh, N. Y. These 



are only a few of the places where 
Du Pont scientists are now at work. 
Each manufacturing department 
does fundamental research as well as 
applied research on new processes 
and products. 

Many types of training 

At any one time, many hundreds of 
different projects are under way in 
these laboratories. Though a rela- 
tively large number of Du Pont tech- 
nical people are chemists and chem- 
ical engineers, other fields of training 
are strongly repre-sented. 

Among the scientists working with 
Du Pont are mechanical, electrical, 
civi], industrial, niining, petroleum, 
textile, architectural and safety en- 
gineers, physicists, metallurgists, bi- 
ologists and mathematicians. About 
30 '^c of these men and women who

are engaged in technical activities 
at Du Pont hold doctor's degrees. 

Interchange of thinking 

All manufacturing departments may 
draw on the services of the chem- 
ical, engineering and toxicological 
laboratories of the company in Wil- 
mington. In addition, the Chemical 
Department's library at the Wil- 
mington Experimental Station cir- 
culates reference material, conducts 
literature and patent searches and 
issues a weekly abstract of pertinent 
articles found in the important chem- 
ical journals of the world. This sup- 
plements normal work of this kind 
done by the various manufacturing 
departments. 

No matter where a Du Pont re- 
search man may work, he has every 
opportunity to use his best talents, 
to advance as his abilities develop, 
and to profit by interchange of think- 
ing with scientists whose minds com- 
plement liis own.

How to keep a rock crusher 
from minding the grind 

In a hammermill rock crusher, every revolution of 
the rotor shaft puts a heavy shock load on its bear- 
ings. Engineers have solved this problem by using 
Timken " tapered roller bearings. Timken bearings 
take the heaviest loads— both radial and thrust. 
They require a minimum of maintenance and 
normallv last the life of the crusher. 



Why TIMKEN bearings can 
take the tough loads 



In Timken bearings, the load is carried on a line

SPRINGBOARD 



TO A CAREER IN 
ENGINEERING 



by J. F. ROBERTS 

Manager, Hydraulic Deparlment 

General Machinery Division 

ALLIS-CHALMERS MANL FACTl'RIXG COMPANY 

(Cradiiale Training Coarse 1919) 




YOU HAVE to Start somewhere— and as 
far as 1 know, flagpole painting is the 
only job w here ) ou start at the top. Next 
best thing is to get in where there arc 
many opportunities, 
and many interesting, 
worthwhile paths to fol- 
low — particularly ifyou 
are not entirely sure 
just what type of work 
you want to do. You 
then ha\e a chance to 
try more than one field, 
and eventually find the 
J. F. ROBERTS ^vork that will gi\e you 
the most in satisfaction and success. 

Growth of Hydraulics 

The field I'm best qualified to discuss is 
hydraulic engineering. Crude waterw heels 
were man's first mechanical source of 
power. Today, in highly perfected modern 
form, they're still a major source of abun- 
dant, low-cost electric power. The field is 
constantly expanding and holds a world 
of opportunity. H) draulic power becomes 
increasingly important to the nation as 
the need for low-cost power steadily in- 
creases. Moreo\'er, a hydraulic plant once 
installed produces energy with a mini- 
mum of manpower. There's no fuel to 
mine, prepare, ship, unload and burn — 
small operating personnel is required. 

Right now at Allis-Chalmers we're de- 
signing and building turbines for vast new 
hydro-power projects, not only for the 
U.S.A. and Canada, but also for Mexico, 
South America, Norway, New Zealand

and the Philippine Islands. We're also 
restoring many veteran turbines to bet- 
ter-than-original efficiency and capacity 
after long years of faithful performance. 
Hydraulics was a field that 1 hadn't 
seriously considered as an undergraduate 
at the OniNcrsity of Wisconsin. I gradu- 
ated as a Mechanical Engineer in 1918, 
and entered the Allis-Chalmers Graduate 
Training Course in January 1919. It was 
there that I got interested in the big 
waterwheels. 

My first assignment was in steam tur- 
bine erection. "Then I mo\ed o\er on the 
In draulic turbine test floor. In May 1919 
1 was sent to North Carolina on the ac- 
ceptance tests of a big hydro-electric 
power installation. I continued with hy- 
draulic field work such as tests and trouble 
shooting until 1925, when I went into the 
sales end of the work. Two years later 1 
left the manufacturing side and became 
H)draulic Engineer for the Power Cor- 
poration of Canada, supervising the de- 
sign and installation of some 15 plants. 

In 1936 I became Hydraulic Engineer 
for the U. S. Go\ernment TV.A, inxohing 
12 projects and 30 large units. I returned 
to Allis-Chalmers in 1942 as Manager of 



the Hydraulic Department— and had the 
unique experience of building some of 
the same turbines that 1 had purchased 
for TVA. 

Vantage Point for All Industries 

These personal notes serve to illustrate 
two interesting facts about the Allis- 
Chalmers Graduate Training Course. 
First, it's tailor-made for each student. 
Since 1904, graduate students here have 
been helping plan their own courses — 
making changes as they went along and 
new interests developed. They've had an 
opportunity to divide their time between 
shop and oflnce — follow important 
projects through from drafting board to 
installation. 

Second, the organization is in close 
contact with virtually all phases of indus- 
try: hydraulic or steam electric power 
plants and utilities; mining, smelting and 
rock products: public works; steel and 
metal working: textiles; food processing; 
flour milling. Allis-Chalmers builds basic 
machinery for all these industries and 
many more. Its engineers, executives, 
salesmen and production experts have a 
ringside seat for industry in action.

THE STORY OF OIL 



COLONEL Edwin Drake's oil well, drilled in 1859, 
produced only 20 barrels daily . . . 

But it gave people a taste of the benefits of petro- 
leum—and a great industry was off to a flying start! 

The first drilling rigs— first refining equipment- 
were adequate for that early demand. 

But invention of the automobile, airplane, Diesel 
engine and other great machines in turn demanded 
gi'eat invention in oil— and old-fashioned equipment 
gave way to scientific research laboratories, modern 
refineries, pipehnes, tankers and tank cars. 



Eacli year demand made them biRRer and better! 

Today, thousands of oil companies with oil fields, 
refineries, bulk plants, ser\ice stations and cost- 
cutting transportation systems— deliver over 1,840,- 
000,000 barrels of petroleum yearly— meet U.S.A. 's 
demands for value in oil. 

And, today, the responsibilities of Soeony-Vacuum, 
one of the oldest companies in the industry, are con- 
stantly mounting . . . 

Unprecedented demand for petroleum products 
calls for expansion in every phase of our efficient, 
coordinated operation . . .

BECAUSE Du Pont is a chemical 
company, you might expect most 
of its technical men to be chemists. 

Actually, there are more engineers 
than chemists at Du Pont. In each of 
the ten manufacturing departments 
there is important work for men 
trained in chemical, mechanical, 
electrical, metallurgical and other 
branches of engineering. 

These departments operate much 
as independent units with their own 
research, development, production 
and sales staffs. In their respective 
fields, they do fundamental and ap- 
plied research on both processes and 
products. Sometimes engineers par- 
ticipate in the early stages of a proj- 
ect. More often, however, they enter 
the picture when the project has 
moved to the point where commer- 
cial production is considered. They 
see it through the pilot plant and 
semi-works stages and assemble data 



necessary for the full-scale plant. 

Even after manufacturing has be- 
gun, development work is continued 
to standardize and improve the proc- 
ess. Normally, engineers whose main 
interest is production and plant op- 
eration take over when the works 
stage is reached. 

Engineers on the technical sales 
staffs help maintain contact between 
Du Pont and its customers. They 
present data on new products and 
guide customers in process develop- 
ment and similar problems. They 
also use their technical knowledge in 
making surveys of possible markets 
for the Company's products. 

In addition to the manufacturing 
groups, the Du Pont Engineering 
Department — a central staff organi- 
zation — requires engineers with many 
types of training. This Department 
carries on its own program of funda- 
mental and applied research. It also 



makes site investigations, lays out 
and designs new plants and labora- 
tories for the manufacturing depart- 
ments. It serves tliem in research on 
process development, on materials 
cf construction and on methods of 
insasurement and control. 

Yes, engineers figure importantly 
r.t Du Pont. Through their teamwork 
vvith chemists, physicists and other 
trained personnel, the Du Pont Com- 
pany produces its "Better Things for 
Better Living. ..through Chemistry."

London with liea\ \ payloads has heeii 
developed li\ (IK. 

I'njiineers described the conipaiativeh 
small but powerful turbo — designated 
the CH9 — as a "significant .-'(Kance in 
our long histor\ of turbosupercharger 
development." 

Turbosuperchargers, \\i<lel\ used h\ 
America's fighting planes in Woild 
War II, are the devices which enable 
airplane piston engines to "breathe" in 
the rarefied air of high altitudes. Spun 
by the engine's exhaust, they compress 
the rarefied air to sea level pressures 
before it enters the c\'linders. 

The new turbosupercharger entiieh 
eliminates the conventional geared supei- 
charger, or the impeller, operating off 
the engine shaft. There are no me- 
chanical connections between engine and 
turbo. Development of a direct cylinder 
fuel injection system for the R-43f)() 
eliminated the major need for a geared 
supercharger which is used to insure 
uniform fuel distribution to the cylin- 
ders. Engineers said elimination of the 
geared supercharger not onh' saves up 
to 500 hp, previoush' drawn from the 
piston engine, but also makes possible 
a more efficient method of cooling the 
combustion air going to the cylinders. 

Airliners cipupix-d with >uch power- 



pl.uifs could fl\ n(in-sto|i fruui Chicago 
to London, .'i distance of 4(H)(I miles, 
carr\ing nearh half as many passengers 
as are now loaded for Chicago to New- 
York flights. Commerical transports are 
unable to make SLich flights at present, 
nor can they fly non-stop from New 
York to London with profitable pay- 
loads. The new powerplants non-stop 
trans-Atlantic flights can be made at 
faster speeds and with heavier payloads 
than is now possible by airliners making 
two stops enroute. 

"skylike" illumination 

Silvrav "Sk>like," a new concept of 
electric lighting with all of the advan- 
tage of incandescent plus the modern 
appearance of fluorescent, has been an- 
nounced. 

An adaptation of silvered-bowl in- 
candescent lighting, Skylike is designed 
for commercial use, and the Silvray 
company pointed out that in addition 
to its appeal because of its dramatically 
different and better illumination, it has 
the advantages of simple wiring, light 
weight, fast installation, freedom from 
service call-backs, and lower cost. 

Skylike's high light output includes 
the utmost utilization of reflected light 
■.\nd an even distribution of comfortable 
fedl-spectrum light. There are no sharp 
shadows, the 90-degree shielding pre- 
vents both direct and reflected glare, 
;uid there is a complete absence of flick- 



ering, blinking, and hum. The output 
can be varied from 2,500 to nearh 10,- 
000 lumens per unit by use of ISO-, 
200- or .?0()-watt lamps; the silvered 
reflector is permanently sealed, ami 
there is no light loss from depreciated 
ceilings, because Skylight carries its own 
S7 per cent reflection f.ictor teiling.

geodetic control 



bif Warren Ml. Uriindt. C.E. '.'i.'t 



Contrasted with p 1 .1 11 c siii\e\ injj, 
"geodetic" sLiiveyiiig is that branch 
where the shape of the earth is taken in- 
to account in the mathematical adjust- 
ment of the field-measured distances and 
angles. 

The primar\' purposes of geodetic sur- 
veying operations are the establishment 
of fixed monuments or stations, as the\ 
are called, on the ground at some dis- 
tance from one another; whose geo- 
graphic coordinates — latitude and longi- 
tude and elevations — have been deter- 
mined precisely. This data provides ac- 
curate control for topographic maps and 
tor plane surveying operations which 
will be mentioned later. 

I'l uinyiildliun 

By way of explanation, to determine 
trigonometrically the length ot one side 
of a triangle, it is necessary to know 
only two angles and the length of 
one side. In a triangulation tlie length 
of the known side must he measured 
very accuratelv. This side is designated 
the base-line. From it the lengths of all 
other sides in the triangulation system 
are computed. The picture shows a field 
party of the United States Coast and 
(jeodetic Survey measuring the length 
of a base-line in Massachusetts. The 
tape they used is made of an alloy called 
in\ar, ha\ing a low coefficient of ex- 
pansion. 

Instruments for reading angles called 
theodolites, similar to a smveyor's tran- 
sit but capable of work of gieater pre- 
cision, are set over the station monu- 
ments at the termini of the base line. 
The angles between interviewing sta- 
tions are read and entered in the com- 
putation, (^ften structures, trees and ob- 
structions prevent the observation from 
the ground so that the instrument and 
observer must be elevated ovci- the sta 
tion mark. This is done with the use 
of towers. It should be emphasized that 
in a tower of the type pictured there is 
no integral connection between the imier 
tower on which the instrument is placed 
and the outer tower which supports the 
observer. This tower, called the Bilb\ 
triangulation tower, and the theodolite 
were designed by members of the Coast 
and (ieodetic Survey staff. 

I he first primary triangulation (pri- 
mary triangulation later officially desig- 
nated first-order triangulation is work

\ide a much needed control for theii' 
charts of the Great Lakes. 

The triangulation net which eventual- 
1\' encompassed Chicago and was ex- 
tended to Lake Erie was commenced in 



ISbl by the accurate measurement of 
a base-line 19,871 feet in length on 
-Minnesota Point, a sand spit in the hai- 
bor of Superior, Wisconsin. 

The original measurement ot the Min- 
nesota Point base was made under the 
supervision of Captain, later General, 
(jeorge C. Meade, the famed Civil W'ar 
hero noted for his victory at ( jcttysburg. 
This base was remeasured in 1870 and 
from it measurements and angles were 
carried through the triangles to Chicago, 
the parties reaching the station at Deer- 
field in August of 1873. 

From the station at Deerfield, lines 
of triangulation were carried around the 
southern end of Lake Michigan in 1874. 

Because of the lack of funds no 
further work was carried on in this 
area until 1877. 

In May of 1877 a site was selected 
between what is now 71st Street and 
Pulaski Road in Chicago and 5Qth 
Street and Archer Avenue in Summit 
for the measurement of a base-line.

Electroenceplialojirapliy is t li e 
study of brain waves, the eyclieally 
varying potentials existing in the 
brain. The existence of these phe- 
nomena was not a recent discov- 
ery: but large strides have been 
made recently in investigation and 
application of results because of 
the advances in electronic tecb- 
n-ques made in the last few years. 

This art'c'e gives a lirief sum- 
mitry of the ph>s;ological phenom- 
en.i and describes the equipment 
anil techniques used in this sci- 
ence. 



The science ot clcctrofiicephalogra|iliy 
(EK(i) is usLiaII\ considered to have 
liad its beginning in the 1 8th centur\ 
with the <h'scover\ of so-callci! "aniniai" 
clectricit\' by (Jalvani. Since that time 
electrical activity of living tissue lias 
been the subject of much experimental 
work. Electrodes ha\e been applied to 
laboratory animals and to all |iarts of 
the human bod\' in the attempt to locate 
new sources of these potentials. 

One of the most easily detected po- 
tentials was found to originate in the 
nuiscles ot the heart. Because of their 
relatively high amplitude and correla- 
tion with the heart beat, these muscle 
\oltages, known as the electrocardio- 
gram when recorded, were the first to 
be studied and applied to medical sci- 
ence. Electrocardiography is n o w a 
standard technique in the diagnosis of 
lu-art disease.

\ears ot careful stud\', he published a 
pa|ier in 1929 announcing his conclu- 
sions that the potentials had their origin 
in the brain. Subsequent reports were 
published onh' to be ignored or dis- 
missed as representing nothing bur 
"stray pickup" noise voltages or muscle 
.urifacts. The first serious recognition 
( lerger received was from Adrian, dis- 
tinguished Xobel Laureate in physiology. 
Since th.it time, the field ol KVA] has 
developed rapidl\, \astl\ improved in-

All living cells exhibit four basic 
forms of activity. They are, to a varv- 
ing degree, mechanical, theiiu;il, chemi- 
cal, and electrical, and none ca i he con- 
sidered independently of the others. A 
single component of activity gives onh' 
an incomplete picture; but, because of 
the limits of human comprehension and 
the inadequacy of instrumentation, it 
may be the only noticeable manifestation 
of the intricate processes going on with- 
in the cell. 

Since living tissue is a complex mat- 
rix composed of individual cells, each 
filled with an electrolytic fluid, it is a 
good electrical conductor. Therefore, it 
is possible to study electrical activity 
through masses of surrounding tissue. 
This consideration, together with the 
very great sensitivity of electrical tech- 
niques, has caused the electrical activity 
to receive the greatest attention. 

The origin of the potentials is ap- 
|iaieiitlv in the neurons of the ccutex 



waves. In general it mav he said that 
the frecpiency is proportional and the 
magnitude inversely proportional to the 
phvsiological activity. For example, the 
cortical potentials of a rabbit increase m 
in frequency and decrease in niagni 
tilde when the ev'c is strongly illumin 
ated. This might be compared to radic

ent areas and lobes of the brain exhibit 
characteristic differences, but there is 
no sharp delineation of this activity. 

The periodic nature of the brain po- 
tentials is their most distinguishing 
characteristic. The frequencies encoun- 
tered r;mge from one cycle per second 
to 60 cycles per second or higher. The 
most striking aspect is the relation be-

is the most satisfactory and is widely 
used. Obviously brain tissue is not di- 
rectly accessible except during a major 
operation, as tor a brain tumor, for 
example. 

There are six standard locations for 
electrodes ordinarily used. T hese art- 
shown in one of the accompanying dia- 
grams. However, when greater localiza- 
tion of certain areas is desired, other 
arrangements are used. 

Of course any potentials must b:- 
measured with reference to some point. 
In the monopolar connection, one lead 
to the amplifier is attached to an in- 
active or neutral area such as the lobe 
of the ear. This is considered inactive 
as it is relatively distant from the brain. 
However, large muscle potentials can 
exist here when, for examph-, the jaws 
are clenched tightly. The other lead to 
th amplifier channel is attached to some 
area on the scalp directly o\er the area 
being studied. 

A second arrangement of input leads 
is called the bipolar connection. In this 
case, both leads are attached to acti\e 
areas. The residting waveform is es- 
sentially the algebraic sum of the po- 
tentials present under each electrode. 

Monopolar leads are used most com- 
monly as the recordings are easier to 
interpret. However, bipolar leads per- 
mit accurate localization of certain dis- 
orders including tumors, abscesses, and 
fractures. All equipment is readily 
operated with either monopolar or bi- 
polar leails.

terminals may damp the movement to 
such a degree that it will not respond 
to the frequencies being studied. 

C^bviously, the many limitations of 
the galvanometer as a recorder led to 
the development of an electronic ampli- 
fying system. Here there was no prob- 
lem of impedance matching; vacinim 
tubes are inherently high impedance de- 
\ices. They are capable of responding 
to all frequencies present in the EEG 
without any of the damping effect en- 
countered in the galvanometer; and, 
with several stages, the desired sensi- 
tivity can be attained. 

However, the practical design of such 
an amplifier posed many problems at 



necessary to use photographic record- 
ing in order to obtain a continuous rec- 
ord. This is a more serious disadvan- 
tage than might be supposed. Aside 
from higher cost, the record is not seen 
until hours after it has been taken, and 
it is therefore difficult to make corre- 
lations between the behavior of the pa- 
tient and the electrical activity of the 
brain. 

Because of these difficulties, the elec- 
trocephalograph remained in the lab- 
oratory and had little clinical use. 

In 1934, Gorceau provided the first 
clinical EEG which was both service- 
able and cheap. It was sensitive to all 
frequencies up to 70 cycles per second

thoven for registering the electrocardio- 
gram. However, the brain potentials 
have an amplitude of approximateh 3U 
micro-volts, or 1-100 of that obtained 
from the heart. The impedence or re- 
sistance of the scalp between electrodes 
is about 10,000 ohms. The low im- 
pedance of the galvanometer seriously 
loads such a high impedance circuit, thus 
further aggravating the sensitivity prob- 
lem. Furthermore, this resistance of the 
scalp shunted across the galvanometer

that time. Because of the extremely 
small magnitude of the volt.ages, an 
amplification of approximately 10 mil- 
lion or 140 decibels is necessary. Com- 
ponents then available such as tubes and 
resistors often produced noise voltages 
over 100 microvolts. The desired signal 
was thus completely masked by noise. 
Amplifier circuits were very unstable 
and had to be continually adjusted 
while in operation. Since a reflecting 
galvanometer was still used, it was 



with a sharp drop in response above that 
point. 

Amplifier Design 
The resistance-capacity coupled, push- 
pull amplifier has been by far the most 
practical EE(j amplifier and is now 
used in all commercial instruments. The 
direct coupled amplifier has been used 
for LL(i but is not ordinarily desirable 
because of the usual instability, drift, 
difficulty of adjustment and complexitj-

AIEE-IRE 
The first official meeting of the 
American Institute of Electrical Engi- 
neers-Institute of Radio Engineers 
served as a general intro- 
duction of the society and 
its activities to new mem- 
bers. The branch counsel-

the show, iiow the \arious efiects are 
produced, and what takes place in the 
fireworks factory. 

The first use of gunpowder was for 
display purposes rather than for war- 
fare. Roman candles, which, b\ the 
way, are of Chinese origin, not Roman, 
were the first form of chemical war- 
fare. Their effect was largely psycho- 
logical, for they are not a very deadly 
weapon. It is conceivable, howc\er, that 
they may have started some small fires. 

Fireworks displays, especially on the 
Fourth of July, are used to imitate the 
noise, smoke, and flame of warfare. 
Their original use in this country was 
to commemorate the Revolutionary War 
with the "rockets' " red glare and the 
bombs bursting in air." Since that time, 
fireworks have improved, their effects, 
however, still based on devices of war. 

Probably the best place to start a 
paper of this sort is with the fireworks 
display itself. For this purpose, the 
writer will attempt to describe in .some 
detail one of the ten shows held at the 
Illinois state fair during 1940, under 
the direction of the Thearle-Duffield 
Fireworks compaiu'. 

As the audience looks from the grand- 
stand to the darkened infield, the show 
begins with a rain of red and green 
fire from the sky. Cluster after cluster 
of flaming balls burst abo\e the heads 
of awestruck spectators. Hetore the 



splendor dies, the ground is illuminated 
by golden showers of sparks, streams of 
which form crosses and geometrical pat- 
terns. The smoke from these pieces is 
lighted with colored lights, transform- 
ing this once objectionable b\-product 
to a thing of beauty. In between the 
poles which support these devices, fiery 
balls of gold and silver sparks are being 
shot twenty to thirty feet in the air. 

Again the sky is split asunder, this 
time with many different types of fire 
and devices. Explosions which rock the 
grandstand are anticipated by brilliant 
flashes of light high in the sky. Whis- 
tling comets soar to the ground, ap- 
parently right over the heads of the 
onlookers. 

Now the ground is alight again, this 
time with brilliant wheels which spin 
around on the top of their supporting 
poles. Following this is a huge pyramid 
or tree of sparks which shower to the 
ground in a gold and siher rain. As the 
tree appears to burn out, the air is split 
with resounding detonations w h i c h 
threaten to break the eardrums of the 
crowd in the grandstand. 

And so the show goes, aerial display 



being intermingled with ground works. 
Small devices which scoot horizontalh' 
over the ground provoke laughter, and 
again the audience is held breathless by 
the white brilliance of a seventy-five- 
foot-long Niagara Falls. 

Flaming portraits of the vice presi- 
dent, the governor, and the majority 
leader bring forth applause from the 
loyal party members in the audience. A 
fift\-by-fifty picture of a field of green 
and \ellow corn changes as it burns to 
a white outline of the state of Illinois. 

"Oh's" and "ah's" of wonder are 
heard as the sky is filled with gold. 
Flowers break in the sky with their 
stems and leaves spreading groundward 
then, at the tip of each stem, a golden 
blossom spreads in a dazzling display of 
beauty. The audience is not given .i 
chance to recover before hell itself 
seems to break loose. 

The show is into the finale. The 
sky is literally filled with red, white, 
and blue flame and resounding salutes. 
On the ground, tremendous explosions 
rend the air and "Old (ilor\ " appears 
in fiery splendor.

the art of sleeping in class 

It is a fairly well .iccepted fact that 
engineers get less sleep than any other 
students. To make up for this lack of 
nocturnal bliss, the student must resort 
to some other means. The most practical 
solution is to sleep in class. This method 
is frequently practiced and has thus be- 
come an art. 

The most practical time to sleep is 
during a lecture. It will frequently be 
found advisable to take a seat near the 
rear of the room where you may black 
out unnoticed by the instructor. ( Some 
inconsiderates have definite ideas as to 
seating arrangement.) 

One problem in this particular case 
is that of keeping the notebook or clip- 
board on the desk. The object may 
easily slide to the floor, thus requiring 
an unnecessary amount of energy to re- 
trieve it at the end of the period. Also, 
certain people receive tremendous pleas- 
ure from accidenth' pushing a clipboard 
to the floor. The clipboard lands with 
a resounding clatter, waking both in- 
structor and students. I have found that 




resting either an arm or the head on 
the memorandum usually will help. 

The position to be assumed for nap- 
ping will vary with the type of seat in 
the classroom. I suspect that many chairs 
were designed for the express purpose 
of keeping the student awake. The backs 
of most chairs are so constructed that 
resting the head on the back (of the 
chair) is the best solution. This, how- 
ever, presents the possibility of snoring. 

Sleeping with the arms supporting the 
head may result in disaster. I nearly lost 
my head once. 

In classes where discussion prevails, 
other problems arise. Instructors in such 
classes may object to this state of activ- 
ity. A friend of mine has solved this 
problem by learning to sleep with his 
eyes open, a process which I have not 
yet mastered. 

It may be embarrassing to come to 
just as the instructor is asking you a 
question. Robert Benchley, in an essay 
on "Dozing" suggested a reply of, 
"Well . . . I . . . don't . . . know." In 
the classroom, however, this may be of 
little or no help. 










?*^ 



The "wide-awake" appearance (left) and the "fixed" look (right) have 
proved, through considerable experimentation, fo be the most restful 
class positions. 



M. E.'s and C. E.'s may finii it 
extremely difficult to sleep in drawing 
rooms. The stools are most uncomfor- 
table. It may even be necessary to sleep 
while standing. A roving instructor will 
not help matteVs any. 

For the novice it may be necessary 
to spend a few nights with less than the 
usual ten hours sleep to get into form. 
Pills guaranteed to keep you awake will 
help to induce sleep. Though the art 
may never be fully perfected, one should 
not become discouraged, for even the 
cruder methods will produce the desired 
results of lengthening one's doze period.

Professor Josef-Marion Gutnayer 

Assi>tanr I'loti'.ssoi- ( riirnaycr is an 
outstanding nifniber ot the faculty of 
the Navy Pier Architcctin'e (ieijartnient. 

He received his training at the Ecole 
Sf>itialc d' Architecture, where the inter- 
nationally known architect, Auguste 
I'erret, teaches. In the followmg years, 
he carried on a practice in Paris where 
he designed and built, in this period, 
buildings considered as pioneers in the 
field of modern architecture. Mr. Gut- 
nayer considers the environment at the 
.irtistic center of Montparnaiisse in Paris, 
with its world-famous architects aiid 
aitists, as the place where he formulated 
his architectural principles in the art of 
building and design. 

In the short period of his work in 
Poland, Prof. Gutnayer was in charge 
of the design of a gigantic nidustrial 
project for the Warsaw Sewage Dis- 
posal plant. The design of this building 
now under construction expresses a 
noble and dignified character of indus- 



trial architectme in line with the great 
principles of the architecture of the past. 

Since coming to this country, Prof. 
Gutnayer has collaborated on the de- 
sign of immense projects such as the Al- 
bany Municipal airport with the engi- 
neering firm of Brinkenhoff, Hogan, 
and Macl^onald. He worked with Skid- 
more. Owings, and Merrill on the Fort 
Hamilton hospital, and he has also de- 
signed school buildings, a home for the 
aged, an extensive housing project, and 
others. 

Since his appointment to the Navy 
Pier branch of the University, he has 
concentrated upon crystallizing his arch- 
itectural principles. His practice and 
teaching is a demonstration of the sensi- 
tivity of the directions toward the de- 
velopment of Contemporary Art and 
Architecture. He believes that "... it 
is mostly by our appreciation ol the arts 
that we differ from the animals."

The officers of the Na\\ Pier stu- 
dent chapter of the AIA for the pres- 
ent semester were announced as fol- 
lows: Ross Parkerson, president; Mai 
Alarkowski, vice president; and Joyce 
Davis, secretary. 

This chapter was the first AIA stu- 
dent chapter in the country. The mem- 
bers have all been invited to attend the 
monthly meetings of the National AIA, 
which are held the first Tuesday of 
every month in the Bismarck hotel. 

The speaker of the October 3, 1950, 
meeting of the parent society was Frank 
Lloyd Wright, who was guest of honor. 

Several Pier students won prizes at 
the National Beaux-Arts Judgment held 
at Navy Pier last June. Francis Piech 
received first prize and David Kurka, 
second prize. Ralph Anderson, Joseph 
Bembenek, Thomas Klausmeyer, and 
(jeorge Watanabe earned first men- 
tions.

The American Society of .Mechanical 
Engineers, Navy Pier chapter, held its 
first meeting in the form of an informal 
discussion. Activities planned iiicliule 
lectures, movies, field trips, and the an-

field trips during the Christmas vaca- 
tion and between semesters, and to in- 
clude fields of interest for both me- 
chanical and general engineering mem- 
bers. 

The new officers for the first semes- 
ter are Richard J. Hofmeister, presi- 
dent; Ken Nerius, vice president; and 
John Grimson, treasurer. 

ASCK 

The first meeting of the N'a\y Pier

1950. 

The speaker at this meeting was Mr. 
A. W. Irvin of the Rail Steel Corpora- 
tion. The topic of Mr. Irwin's talk was, 
"Uses of Rail Steel in Manufactining 
of Reinforcing Bars." 

All student ASCE members of the

... on the face of the universe," was an opt definition once given in an 
English class, concerning this planet. 

The article on electroencephalography in this issue of TECH may be the 
opening to a phase of research for which Man has been seeking for centuries— 
the intangible substance known as "life." Perhaps this probing of the human 
brain and the proving of the theory that every human emotion and thought is an 
electrical impulse, will shortly set down, in one concise mathematical expression, 
the secret of Man's existence. Knowledge of this may lead to the Age of Man 
Creating Man. An even later era may no longer see the "Earth" occupying its 
tiny niche in this corner of the universe. 

We undergraduate engineers lift an eyebrow and grin at such a crackpot 
idea as this. On second thought, though, considering the advancing age in which 
we live, do we any longer have the right to label ANY idea as "crackpot?" 

Engineering principles laid out the design for the electroencphalogrophic 
apparatus. Similarly, engineering devices are laying out for inspection, data 
from the outside universe as well as the secrets of the tiny world of atoms. 

To what objective does this editorial lead? None. 

Except to perhaps stimulate some thought on how the Engineer is molding 
the Future and what his ideologies and philosophy should be with this responsi- 
bility resting on his shoulders. Perhaps through him, this fly-speck need not 
disappear from the heavens.— C.W.M.

How to make 16

at the cost of 1 . . . 



These odd looking little gadgets, called "pawls," 
go into high speed telephone dials used by Bell 
System operators. 

Until recently, pawls (like the black one) were 
made of molded rubber with a steel pin for the shaft. 
They did their job well and lasted a long time. But 
Western Electric engineers decided to try to make 
them at a lower shop cost. 

The engineers came up with an idea — mold the 
pawl, pin and all— in one piece of nylon. They made 
some samples — tested them thoroughly — found the 
nylon pawls would last as long and perhaps even 
longer in service. Bell Telephone Laboratories tested 
them— and approved. So Western Electric engineers 
tackled the production problems — designed new 
machinery for molding pawls in one piece. It wasn't 




easy — because all dimensions had to be controlled 
with extreme accuracy. But today the new nylon 
pawls are being made in quantities— j/.v/ee« of them 
for the cost of one of the old type! 

This story of cost reduction— and there are scores 
of others like it — shows one way that Western 
Electric engineers help to keep down the cost of 
equipment produced for Bell Telephone companies 
and, therefore, the cost of service to telephone users.

The new home of the Westinghouse 
Educational Center where new em- 
ployees from engineering colleges 
receive an orientation and training 
program to help them find the kind I 
of work they like to do and are 
likelv to do best. Hundreds of ex- 
perienced professional people help 
carry out this program. A Graduate 
Study Program is also made avail- 
able through which advance- 
degrees may be obtained. 



A PRICELESS ASSET... 



Building solidly for tomorrow is an important 
phase of modern business . . . building men 
for positions of leadership. 

For more than half a century, Westinghouse 
has placed major emphasis on this activity . . . 
pioneering in student training . . . graduate 
study courses . . . encouragement of scientific 
training through scholarships and fellow- 
ships . . . and in many other ways. 

Now we dedicate an entire new building 
to this purpose — the Westinghouse Educa- 
tional Center— a building devoted to the self- 
improvement of men . . . dedicated to de- 
veloping leadership. 

Here, top students who are recruited at 
leading engineering schools for positions 
in engineering, manufacturing, sales and re- 
search, come for an orientation and training 
course that provides their first intimate view 
of the electrical manufacturing industry . . . 
and the varied opportunities it offers. 

Every facility has been provided to help 
these men get off to a firm, fast start . . . mod- 



ern class rooms equipped for visual education 
... a large auditorium with complete stage 
and projection room facilities . . . and a large, 
comfortable library and study hall. Here an 
intensive course of study is given by engi- 
neers and scientists who are top-ranking men 
in their fields. 

These same facilities are also adequate to 
take care of the needs of post-training-course 
employees who are participating in the 
Graduate Study Program and the many other 
educational activities of Westinghouse. 

For their convenience and comfort, there 
is a cafeteria and generous space for formal 
and informal gatherings. For relaxation and 
recreation, there are hobby, billiard and game 
rooms and outdoor recreation facilities. 

Here, then, is a building dedicated to 
developing leadership . . . that priceless 
asset of a strong organization . . . able 
management and professional leadership 
for tomorrow. Another reason we say with 
confidence . . . G-10116

Aided by the most modern facilities, experienced 
professional people provide a panoramic view 
of the research, engineering and manufacturing 
that go into Westinghouse products and the 
techniques used in marketing them. 



In planning the new Educational Center, careful 
thought was given to recreation. A spacious lounge, 
hobby and game rooms, a billiard room, facilities for 
indoor and outdoor sports along with a convenient 
cafeteria — all contribute to a well-rounded program.

which he serves the 'l'cihni)(/r(iph is that 
of faculty advisor. 

It's a matter of conjecture to some 
who haven't met him before as to 
whether Mr. Foster, who has gained 
in stature, has lost an\ of the campus- 




GEORGE FOSTER 

student traits he possessed tiiat short 
time ago. Those who have made his ac- 
quaintance or who have known him, say 
that he still retains that likable, boyish 
grin he wore during his undergraduate 
days. 

-Mr. Foster was born August 2\ 
1921, in Minneapolis, .Miiuiesota. He 
attended some 12 grade schools — from 
a country school in Wisconsin to a 
similar one in Pennsyh ania. In high 
school he was a member of the Na- 
tional Honor Societ\. 

He spent two antl a half \ears in the 
L . S. Navy, and served as an instructor 
during his last year and a half. After 
the war he taught in the New Milford 
grade school in Illinois. 

Late in 1946, he enrolled at the Uni- 



versity of Illinois and subsequently was 
circulation manager, associate editor and 
editor for the lUiiinis 'rcchnogi iif>h. He 
recciveii his bachelor of science degree 
in electrical engineering in 1948. 

Currently, he is assistant editor at 
the Engineering Experiment Station at 
the University. He is aLso studying for 
his master's degree in electrical engineer- 
ing. 

From l')4S to late this \ear, Mr. Fos- 
ter has been responsible for the editing 
and publishing, and in sonic cases, the 
actual writing of the quarterly or bi- 
monthly progress reports which are re- 
quired under the terms of the various 
.'\rmed Forces contracts for research in 
the electrical engineering department. 

Last year Mr. Foster was responsible 
for writing some of the material and 
publishing the 128-page booklet, "Ca- 
reers in Engineering," which is used 
by the College and University to an- 
swer inquiries from prospective students. 

Since 1948 he has also been teaching 
the senior elective course in Engineer- 
ing Reports, which is handled on a co- 
operatixe basis with Professors Winde- 
sheim and Heater who present the ma- 
terial dealing with oral reports and il- 
lustrations, respectiveh'. 

-Mr. Foster was married June 1, 1947, 
and devotes considerable time to his 
wife, Florence, and their daughter, 
Karen Marie who is two years old. 
Though not a philatelist, he collects 
stamps — any kind, any year. He also 
bowls and plays golf. 

Mr. Foster is deeply interested in 
technical writing and publishing as a 
future profession. It is his belief that 
this field is wide open to engineers who 
are interested in technical writing. It 
usualh' takes five to ten years for a 
non-engineer to acquaint himself with 
the technical field, but an engineer can 
easily fill a position of this type if he 
has an aptitude for writing.

Kansas. After finishing her Ireshman 
year there she attended summer school 
at Colorado University, and then in the 
fall of 1948 came to the University of 
Illinois. Here she switched to electrical 
engineering, taking the illumination op- 
tion. 

During her first year on this campus 
she was appointed office manager of the 
AIEE-IRE Student Branch, and pub- 
licity chairman of the St. Pat's Ball 
committee. Jo accomplished this while 
carrying a twenty-hour academic load 
including calculus and both semesters of 
physics. 

But she was only warming up. Dur- 
ing her junior year she edited the AIEEl- 
IRE newsletter, the What Miiir; acted 
as national AIEE corresponding secre- 
tary; Illuminating Engineering Societ\' 
secretary - treasurer; a n d attendance 
chairman of Block I. In her spare time 
she took fhing lessons at the Uni\ersit\ 
Airport. 

Jo's interest in electrical engineering 
may be attributed to a lifelong exposure 
to her father's profession ; Dr. V. P. 
Hessler is a professor in the E. E. De- 
partment. She has a wide range of

Just as snug harbors ofi'er ships protection from stormy 
seas, there are protective coatings today that guard them 
against sleet, snow, salt spray— and other damaging forces. 

There is a plastic coating for ships' hulls that eases the 
age-old problem of barnacles and rust, ^essels stay in serv- 
ice twice as long between costly lay-ups in drvdock for 
cleaning and painting. Top-side and below, there are long- 
wearing coalings to keep the modern craft ship-shape. 

Tankers at sea— and tanks ashore— get double protection, 
inside and out, from plastic coatings. Contents stay clean 
and pure, never touching the tank wall. The tank itself is 
safe from attack by water, acids, alkalies, or other chemicals. 

These sea-going coatings are made of the same kinds of 
jilastics that serve us so well in industry and in our h<imes. 



In a triumph of synthetic chemistry, these ever-useful basic 
materials are produced for us from organic chemicals. 

The plastics and chemicals for these improved coatings 
are but a few of the hundreds of better materials sujiplied 
by the people of I nion Carbide to serve shipping and many 
other industries.

{ I iiiiliniu // jt'iiii [>,ii/, 1 ) 

tor the Lake Sur\c\ by Rcpsold of (Ici- 
niaiiy, consisted ot two parallel metal 
bars of zinc and steel approximately 4 
meters in length and fastened firmly 
together at their centers; the whole as- 
sembly placed in a tube supported abo\e 
the ground by tripods at each end. 

The procedure with this type of ap- 
paratus is to center one end of the tube 
ii\er the station mark at either terminus 
of the base-line, by means ot an intri- 
cate microscopic device. The opposite 
end of the tube is fixed and the micro- 
scope at that end is brought o\er the 
end of the bars, the microscope is 
clamped and the tube is raised off its 
tripod and carried forward to place the 
rear end of the bars under the former 
front microscope. The front end of the 
tube is placed on another tripod on the 
line of the base and the microscope at 
that end is brought over the ends of the 
bars as before. 

Measuring the Chicago base-line in 
both directions with this apparatus re- 
quired S4 days. The average distance 
measured per day was 958 teet, the 
greatest distance measured in one day 
being 1,640 feet. Total length of the 
Chicago base-line was 24,6,^ S feet. A 
base measured near Fond du Lac, Wis- 
consin was used in computing geographic 
positions between it and the Chicago 
base. The length of the Chicago base 
computed through 29 triangles or 150 
miles from the Fond du Lac base was 
found to be ±0.275 feet different from 
the actual measured length ! 

Certain of the stations established b\- 
the Lake Survey in 1874-77 were 
utilized by the Corps of Engineers in 



executing a triangulation along the .Ship 
Canal and Illinois Ri\er in 101(1, 

This triangulation, designated as the 
Illinois River Survey, was under the 
direction of J. F. VVocrman, an engi- 
neer of the Corps, and pro\ ided the 
necessary control for maps for the im- 
pr()\ement of the Illinois waterway 
which has now been completed. 

The stations of the Illinois River Sur- 
vey are in rather close proximity to 
one another, being only 4 or 5 miles

apart to give a close check on the ac- 
curacy of the large scale plans tlrawn 
for the waterway. 

Several stations of the Lake Survey 
which could be recovered, were occu- 



pied by a field party of the U. S. Coast 
and ( "leodetic Survey in 1944 to de- 
termine distances between selected points 
for the U. S. Army Air F'orce. 

A few new stations were established 
at this time and as man\- of the Lake 
Survey monuments as could be found 
70 >ears later were reset with concrete 
posts and tablets explaining the pur- 
poses of the mark. The l.ifest year that 
a triangulation p,irt\' opei.iteil in this 
area was 1944. 

Summarizing, a triangulation pro- 
vides the basic framework for maps of 
even minor accuracy, since its existence 
or the lack of it means the difference 
in maps of great value or worthless for 
engineering applications. The Chicago 
area has been inadequately covered by 
triangulation by reason of the great dis 
tance between the stations. Were it not 
for supplementary stations established 
by other methods of survey, adequate ac- 
curate control of this area would not 
exist.

The first topographic mapping in this 
area was b\- the United States Cieologi- 
cal Survey in 1889, using reconnaissance 
methods based on a \ery few control 
points. The region was also mapped 
geologically at this time and the results 
printed in an interesting report show- 
ing the surficial geology of the region. 

By 1925 the rapid growth of the 
city had made the old 1889 maps obso- 
lete, also the sparsely located control 
monuments made it difficult for local 
surveyors to determine the location or 
elevation in relation to a fixed point. 
Accordingly an agreement was entered 
into by the Illinois State Geological 
Survey and the United States Geologi- 
cal Survey to map Cook County on a

You've read, in both newspapers and 
magazines, about the powerful elec- 
tron microscope. Now this amazing 
"instructor" of scientists, physicians, 
and engineers becomes even more 
useful— in more research fields. 

Through principles uncovered at RCA 
Laboratories, RCA engineers have devel- 
oped a compact "table model" electron 
microscope, at a price which makes it 
practical for use in an increased number 
of universities, industries, hospitals, clin- 
ics. So simplified is the new instrument 



that even a high school student or im- 
skilled laboratoiy technician can quickly 
learn to use it ! 

Magnifications of 6000 times can be ob- 
tained directly in RCA's portable electron mi- 
croscope — four times that of ordinary light 
microscopes — and photography lifts this to 
30,000! A new "instructor," yes — and one 
that gets a very hearty welcome.

GEODETIC CONTROL . . . 

( tdiiliiiiii d jioi.i pdji- _'(!) 

scale ut 1" to 2000 feet ( 1 :24,{)()() ). 

It was ik'termiiieii that the lumiber ot 
control points necessary to furnish ac- 
curacy to the proper degree for the maps 
on the selected scale could onl\ be pro- 
\ided b\ an extended traverse net cov- 
ering; the entire county. 

The methods of runninii a traverse 
are similar to a triangulation with se\- 
eral notable exceptions. A traverse is 
run entirely on the ground with dis- 
tances betv\een stations of only a few 
hundred feet. All distances are mea- 
sured with a steel tape and angles from 
station to station are read with a tran- 
sit. Third-order accuracy in llus work 
is acceptable. 

Checking a traverse pro\ides for 
lines to be run in a grid pattern, each 
line beginning and ending at a point 
whose geographic coordinates have been 
determined. Further checks are made by 
connecting a traverse line to be an exist- 
ing triangulation station. 

In Cook County lines of traverse 
were run on many of the major high- 
ways and the geographic coordinates of 
section corners, road intersections, prom- 
inent landmarks, etc., were determined. 
Railroad trunk lines were also utilized 
for this purpose, the traverses extending 



almost to the doors of the depots in 
downtown Chicago! 

The total length of traverse lines run 
to control the Chicagoland topograjihic 
maps was 493 miles. 

Later plane-table p a r t i e s utilized 
many of the traverse stations as check 
jioints in their field drafting of critical 
portions of the county. Not all ot the 
county had to be mapped by plane-table 
as aerial photography provided tin- re- 
maining cultural information. 

Levi hill/ 

Upon completion of traverse work, 
level parties took to the field, determin- 
ing elevations abo\e mean sea le\el for 
all of the monuments set during the tra- 
\-erse in addition to many supplementary 
points. 

I'Or vertical control of topographic 
maps, third-order accuracy is specified 
by the U. S. Cieological Survey and this 
is accomplished with an engineer's w\e 
level. Elevations are determined to the 
nearest .001 foot. 

Lines of accuracy greater than third- 
order were run by the Corps of Engi- 
neers along the Illinois and Michigan 
Canal in 1903, and by the Coast and 
(Geodetic Survey on the Milwaukee 
Railroad from Savanna to Chicago in 
18iS3. The latter survey also ran a line 
of levels on the Rock Island and New 
York Central Railroads into Indiana 



in 1916. Parties of the Geological Sur- 
vey tied their level circuits into these 
lines of greater accuracy to bring the 
entire survey into the National level net. 

Thus the Geological Survey after run- 
m'ng 464 nu'les of levels adequately con- 
trolled their maps of Chicago and vicin- 
ity. Permanent monuments were set at 
convenient places and their elevations 
were determined to a sufficient accuracy 
to make them useful for future work. 

While not being geodetic in nature, 
permanent monuments set by the Rureau 
of Sewers of the City of Chicago are 
worth\ of notice. These bench marks — 
monuments whose primary purpose is 
to provide elevations rather than geo- 
graphic coordinates — are set by the Bu- 
reau to third-order or greater accuracy. 
The work has been in progress for about 
50 years and the elevations have been 
checked and rechecked with federal 
monuments so that for all purposes it 
may be said that these marks are of geo- 
detic accuracy. 

During the latter period of the na- 
tional depression in 1934 and 1935, the 
federally constituted Civil Works Ad- 
ministration undertook an extension of 
the vertical control lines in Northern Il- 
linois. These level parties were under 
the supervision of personnel of the 
Coast and Geodetic Survev with the 
party being made up of local unem-

THE TECHNOGRAPH 



pliiyi-ci iiu'ii with Mn\ey experieiicf. 

Lines run by the C. W. A. at this 
time included a releveling of the 1883 
Coast and Geodetic Survey line on the 
Milwaukee Railroad from Savanna to 
Chicago. Many of the old monuments 
h.id been destroyed and this survey re- 
placed them. A new second-order line 
trom Chicago to Milwaukee on the 
North Western and Milwaukee Rail- 
roads was also run by this party. Con- 
siderable work was done in the Fox 
River valle\- and westward, bringing 
formerly uncontrolled areas into the na- 
tional level net. 

At the present time the Cook County 
Highway Department is executing a 
precise level survey around the country 
and outside the city of Chicago. This 
work is under the supervision of an em- 
plo\ee of the Highway Department who 
has trained with Coast and (jeodetic 
Survey personnel. The instruments and 
methods used in surveying are compar- 
able to federal first-order work. 

The plans of the Highway Depart- 
ment call for a bench mark each ■/) mile 
on the township lines and additional 
marks on the routes of the projected 
superhighways. About 300 miles of lev- 
els have been run up to this time, some 
with federal assistance. 

The Coast and (leodetic Suivey will 
compute and publish the elevations for 
the monuments set by the Highway De- 
partment insuring geodetic accuracy for 
each mark. 

In summary, extension of the original 
Lake Survey horizontal control was ac- 
complished by traverse primarily intend- 
ed to provide accurate data for the Chi- 
cago topographic map. In addition, 
many miles of levels were run through- 
out the area so that adequate vertical 
control can now be said to exist. 

J />/>/iciilions of Giodctir Data 

As stated previously the primary pur- 
poses of a geodetic survey is to provide 
geographic coordinates and elevations of 
known points for the construction of 
accurate maps and charts. 

How may this data be utilized by the 
engineer who is familiar with plane 
surveying but not so familiar with geo- 
detic operations? 

For one thing, the geographic coordin- 
ates for all triangulation stations have 
,ilso been given in terms of plane co- 
ordinates on a definite state-wide grid 
system. The use of plane coordinates in 
reference property corners is increasing. 
Referencing a piece of property to a 
triangulation station is literally putting 
that piece of property on the map. 

The engineer can run a simple tra- 
verse from the triangulation station to 
the corners of the property in question. 
Then, on forms provided by the Coast 
;uid (Geodetic Survey, he may compute 



the plane coordinates for each corner. 
If desired, the coordinates which are on 
an .V and Y system may be expressed 
in terms of latitude and longitude. 

The uses of bench marks are numer- 
ous. Any work which requires a refer- 
ence to a point of known evaluation 
must have accurate vertical control 
monuments. Such projects as highway 
and railroad construction all involve 
the setting of grades. Often these proj- 
ects are of such magnitude that the 
only method of checking the accuracy 
of the engineer's work is to refer the 
termini of the project to a gcodetically 
determined bench-mark. In fact, all pro- 
files submitted by railroads to the Inter- 
state Commerce Commission in com- 
pliance with the valuation order must 
have a reference to sea level elevation. 

In general, results of geodetic opera- 
tions are published by the department 
that executed the survey. All the engi- 
neer need do is to write the department 
stating the extent of his requirements 
and the full descriptions, geographic co- 
ordinates, or elevations for monuments 
in his vicinity will be furnished him. 

The increasing uses of geodetic sta- 
tions and the accuracy of information 
about them bind the engineer to use 
every care in preserving these moiui- 
ments. They represent not only time and 
effort, but the considerable funds (usual- 
ly taxpayers') spent to establish them. 
Often persons ignorant of the purposes 
of these monuments have destroyed their 
usefulness in the quest of souvenirs, or 
for some other reason. When a survey 
monument is lost the effects are not 
immediately noticed. But when an engi- 
neer comes to use the monument and 
finds it destroyed its value becomes ap- 
parent. 

There is a federal law prescribing 
fines and punishment for persons mali- 
ciously destroying government survey 
monuments; however, it is far better to 
acquaint all persons with the purposes 
of these marks so that their usefulness 
and value may be appreciated.

encouiitiMcd in this type of ciicuit. Al- 
though imperative in some phases of 
bio-electric work, frequency response 
from one cycle per second down to di- 
rect current is of little interest in the 
usual encephalojiram. 

Transformer coupling is feasible but 
design would be difficult because of 
stray magnetic pickup in the low level 
transformers, and core saturation at tin- 
low frequencies. 

The unusually low frequency re- 
sponse required necessitates a time con- 
stant of at least .5 second. The advan- 
tages of using push-pull in early stages 
are : ( 1 ) avoidance of extraneous pick- 
up, (2) freedom from interference be- 
tween channels and. (3) improved 
amplifier stabilitv. 

The operation of the push-pull cir- 
cuit is such that a differential (out of 
phase) signal must be applied to the 
input grids for amplification to occur. 
All voltages applied in phase will pro- 
duce the same change in plate current 
in each tube. If the circuit is balanced 
and the tube characteristics are identi- 
cal, the net change in voltage between 
plates will be zero; and there will be 
no signal output. However, a change 
in grid voltage (ej applied as an in- 
crease to one grid and a decrease to the 
other, will cause a relative plate vol- 
tage proportional to ke^: where k is the 
stage gain. 

Since neither side of the input circuit 
must be grounded in the push-pull cir- 
cuit, most extraneous pick-up will occur 
as in-phase voltage on the input. By 
proper design, balancing can be made 
so nearly perfect that no more than 
1/50,000 part of the unwanted signal 
between ground and the tvA-o grids is 
amplified. The tapped resistor is usual- 
ly provided to obtain optimum balance. 
The use of the dual triode constructed 
with both units around a common cath- 
ode such as the 6SC7 reduces the effect 
of variation of tube characteristics. 

The other important advantage of 
push-pull is that it allows two or more 
channels to be operated independently 
of each other, making it possible to ob- 
serve waveforms from several areas of 
the brain simultaneously with inter- 
reaction. For this reason the use of a 
single ended amplifier design is unde- 
sirable since the coupling occurring by 
virtue of a common ground effectively 
connects half of the electrodes in use 
together. 

Inverse feetlback is used to further 
discriminate against in-phase potentials. 
A simple feedback scheme is to connect 
the input grid return to the common 
cathode resistor in stage two. In-phase 
potentials increase the total current 
flow through the cathode resistor of 
the second stage. The voltage thus gen- 



24 



crated by this increased current flow is 
180° out of phase with the in-phase 
potentials on the input grids. 

Oiill^iit Stage /mil Rerordiiu/ Sysh in 
As the recording system is usually a 
magnetic drive linked to a syphon pen, 
power is required for its operation. The 
triode is more satisfactory as a power 
amiilifier since a lower plate resistance 
simplifies the problem of impedence 
matcliing. It is interesting to note that

design of an output transformer cap- 
able of operating down to one cycle 
per second would be difficult due to core 
saturation at this low frequency. One 
satisfactory recorder was constructed 
using a permanent magnet field yoke, 
a 300 ohm voice coil, a simple lever 
system, and length of hypodermic tub- 
ing for the pen. In this case, the power 
loss due to the miss-match from the 
tubes to the 300 ohm coil was con- 
siderable but was preferred to frequen- 
cy discrimination and distortion had a 
transformer been used. 

The piezoelectric effect was applied 
to the inkwriter problem by Offner in 
1936. Disadvantages of the Rochelle 
salt crystal unit are an increase in sensi- 
tivity with temperature and hysteresis ; 
i.e., a given signal may cause an up- 
ward deflection of "i lum and a down- 
ward deflection of 4' _.//(/;;. 

Construction 

In practice, wire wound resistors 
must be used in low level circuits as 
the carbon type produce too much 
noise. Likewise, oil filled condensers 
are desirable to reduce leakage to a 
minimum. The value of plate resistors 
in the first stage is critical with re- 
spect to noise and should be kept as 
low as feasible. 

Freedom from mechanical vibration 
of the low .stages is essential. This 



may be achieved by shock mounting 
and isolation of the preamplifier unit. 
Due to the very low input level, the 
intensity of ()(l c\cle fields in most 
buildings, and the nearness of 60 cycle 
frequencN to that of brain waxes, com- 
plete shielding is absolutely necessary. 
The patient must be placed in a scieen 
cage carefully bonded together and 
grounded at a single point. Nearby 
motors, power cables, and teliplione 
lines must also be shielded. 

Resonant filter circuits are often 
used to effect a 30 decibels decrease 
in 60 c\cle interference. However, the 
frequenc\- response of the amplifier is 
then flat to only 45 cycles per second 
or lower. 

(jondusioiis 
The waveforms recorded probably 
consist of many separate w aveforms, 
each originating from some particular 
locality in the brain and supermiposed 
upon each other. The difficulty in lo- 
calizing the source of the potentials is 
of course aggravated by the necessity of 
attaching the pickup electrodes extern- 
ally and not to the specific areas of the 
brain being studied. Perhaps it will be 
possible to isolate these poter.tials and 
correlate them with specific actioii or 
thonghts. 

One of the most exciting futme out- 
growths of brain potential study may 
be a means of supplementing or sup- 
planting an impaired or destroyed sense. 
Experiments have been conducted in 
which a deaf person was made to hear 
by direct electrical stimulation of the 
auditory nerves. The author believes 
that similar stimulation of the optic 
nerve may someday be realized, per- 
haps allowing partial restoration of sight 
to the blind by electronic means. 

In the field of electroencephalography, 
there remains much to be accomplished. 
Although the present techniques are 
highly developed and of considerable 
value in medical diagnosis, there remains 
many channels of research with the pos- 
sibility of opening new techniques and 
applications which ma>' yield informa- 
tion on the structure and operation of 
the brain.

Why we knoAV this wax carton will stand up 



Cartons and wrapping papers coated with 
paraffin wax have been used in food packag- 
ing for many years. They must be able to 
withstand rough treatment. Their ability to 
stand up depends largely on the strength and 
sealing qualities of the coating agent. Yet 
until a few months ago, there was no accu- 
rate way to measure these qualities in paraf- 
fin wax. 

Recent experimental work in Standard 
Oil's laboratories has resulted in a new elec- 
trically controlled quantitative test. Ex- 
pressed as Indiana Coating Index, this test 



gives, for the first time, an accurate yard- 
stick of wax qualities which may be corre- 
lated with performance in service. It makes 
possible the production of uniformly high 
quality coating agents. 

The Indiana Coating Index is only one of 
many scientific tests developed in Standard 
Oil laboratories. Standard pioneered in qual- 
ity-testing, as it did in developing many 
petroleum products that have contributed to 
better living. There is no ceiling on what can 
be accomplished by Standard Oil researchers, 
present and future.

{ritiiliiiiitil jriiiii t>aiii 11 ) 

The show is ovit. In tittiTii <ii

has taken to tell, $!,()()() worth of m:i- 
terial and labor have K"!"' "P '" snuike. 
It took eif;ht men all day to prepare 
the show, and now the\ are ready to re- 
peat the job tomorrow. 

All the effects of the show just de- 
scribed were produced by a few basic 
pieces of fireworks material. These basic 
items include shells, rockets, tourbillions, 
lances, Roman candles, <;erbs and as- 
sorted noise-makers, i n c I u d i ng fire- 
crackers three inches in diametei- and 
sticks of dynamite. It is the fireworks 
crew's job to combine these pieces in a 
predetermined arrangement to produce 
the desired spectacle when fired. 

Perhaps a brief explanation of the 
various pieces and their effects is in 
order. Shells and rockets are similar in 
that both are aerial pieces. They are dif- 
ferent, however, in most other respects. 
Although the audience may think they 
are seeing sky-rockets when they see 
aerial displays, they are not unless the 
show is being fired over water or in a 
very barren area. 

The reason is simple. The sk\ -rocket 
consists of a tube of powder called 
"propellent " or "rocket composition." 



When this powder burns, it forces ,i 
si re.im of hot gases out of a small hole 
ill the h.uk of the rocket. This forces 
the rocket in the opposite direction in 
accordance with the law of action and 
reaction. The rocket is being driven 
all the way up to its peak of ascension. 
To balance it in flight, it is pr(j\ided 
with a long stick which exten l^ in hack 
of it. It is because the paper tube con- 
taining the propellent and the stick 
sometimes catch fire that the rocket is 
not used over populated areas. The 
burning stick and tube could easily 
set a fire where they fell. 

In lieu of the rocket, the shell is 
used. The shell does not have the fiery 
tail behind it as a rocket does, but it 
is safer. The safety lies in a different 
means of propulsion. The shell consists 
of two parts, the ca.se containing the 
stars and whatever devices are to be 
released in the air, and another section 
containing the "lifting charge." The 
shell is fired from a mortar or pipe. 
Its principle of propulsion is exactly 
the same as that of a bullet. All the 
force is applied to it while it is in the 
mortar. When the fuse is lit, a time fuse 
to the contents of the case is lighted, 
along with the lifting charge. The time 
fuse is timed so as to release the con- 
tents of the case at about the peak of 
elevation, which mav be anvwhere from 
300 to 1,000 feet in the air. 



•Shells conn- in five standard sizes, 
three, four, fi\e, six, and eight inches 
ill diameter, and cost anvwhere from 
i?l to $75 each. Eight-inch shells, al- 
though not commonly used by smaller 
fireworks companies, can be had from 
most companies by special request. 

Tlif outward .ipiiearance of the shell 
gi\es no indication of the l'iL'aut\' and 
splendor it will release when lighti-d. 
.\lan\' shells are wrapped in dull brow ii 
kraft paper and look like a cylindrical 
object wrapped in a common grocery- 
store sack, the neck of which has been 
tied with a rope. Actually, this "rope" 
is the fuse for the shell. The shell is 
jMit into the gun or mortar, fuse end up. 
When ready to fire, the operator merely 
lights the end of the fuse. 

Closely akin to rockets because of the 
powder used in them are "skimmers," 
"wheel-drivers," and "tourbillions." 
Skimmers are the comical devices which 
skim along parallel to the ground. They 
are fired in pairs, one starting from 
each side of the field. It appears as 
though they will collide in the middle, 
but they never do, and for a very good 
reason. The skimmer is actually a small 
rocket without a stick. It slides across 
the field on a wire. A double-track s\s- 
tem is used, one wire for each direction. 

A wheel-driver is just what its name 
implies. It furnishes the motive force

LOOK FOR THIS RIDGE 




AND 

YOU FIND A REASON 



• There is more than mere identification value in the 
lidge you see on Okonite wires and cables. The ridge is 
proof that the insulation has been folded around the con- 
ductor by the well-known Okonite strip insulating process. 
This method permits inspection at all times during the 
application operation. It assures the perfect centering of 
conductors so important to the avoidance of electrical 
failures. 

The ridge is a permanent mark of an Okonite cable. It is 
still prominent after the final vulcanization in a metal mold 
that insures equal transfer of the heat throughout every 
portion of the insulation. The Okonite Company, Passaic,

PROBLEM — You are designing a telescoping radio antenna 
for automobiles. You want to provide a means for extend- 
ing and retracting the antenna sections from a convenient 
point inside the cor. How would you do it? 

THE SIMPLE ANSWER — The illustrations show how one 
manufacturer did it — with two S.S.WHITE 
FLEXIBLE SHAFTS. One shaft, operated from the 
control knob, turns a reel at the base of the 
antenna. The other, on the reel, pushes up and 
pulls down tho antenna sections as the reel is 
turned. As S.S.WHITE shafts con be supplied In

tor whi'fls. Spectacular in its own 
right, fjiving forth a stream of sparks, 
it is usually conihiiu'il with othiM pieces, 
hright flares, ficrhs, or some otiicr de- 
vice. It, too, is just a rocket without a 
stick. 

The name "tourbiliion" comes from 
tile French. In lull it is tour/iil/ioii /!< 
fell, or whirlwind of fire. The tourbil- 
iion consists of a paper tube approxi- 
matel\ two inches in diameter and 
twelve inches lonfi. The walls of this 
tube are very thick. It is fillcii witli 
rocket composition. A narrow stick is 
nailed to the tube crosswise at the cen- 
ter. In use, the tourbiliion is placed 
on a flat surface, stick down. Once 
lighted, it spins around at Ljreat speed, 
and then rises into the air se\er.il fec't. 

Also similar to a rocket in composi- 
tioti is the device called a "merry-go- 
round" or, briefly, "merry." It is made 
up of two tubes identical to those used 
in the tourbiliion. The fub;-s are both 
glued endwise to ,i wooil rod so that 
the merry is .somewhat over two feet 
long. The wood plug at the center is 
drilled for a nail which will serve as 
■A pi\()t. When lighted, a stream of 
sp.irks and hot gases shoots through 
holes in the sides of the tube at the 
end faithest fi'om the pi\ot, causing the 
tube to spin with great speed. 

Besides the various rocket devices, 
there are a few more basic pieces used 
in the show. One of the most nuportant 
of these is the gerb. A gerb produces 
a shower or fountain of sparks. It, too, 
consists of a pa|ier tube suiul.u' to those 
previously mentioned. 1 hese are filled 
with a powder composition containing a 
high percentage of powdered and flaked 
metal. Whether the gerbs are gold, sil- 
ver, aluminum, or some other color de- 
pends chiefly on the other ingredients 
in the mixture and not the metal used. 
In use, these tubes are fastened to poles 
so that the streams of sparks they pro- 
duce will cross and form patterns. 

When made up on poles like this, the 
whole device is called a totem pole. 
Gerbs also were vised on the tree or 
pyramid described in the first part of 
this article. (lerbs are often used in 
conjunction with merries or wheels, and 
in general, form a very useful part of 
the pyrotechnician's material. 

Similar to the gerb is the cascade 
piece. The nuxture in the cascade piece, 
or shower stick, as it is son-ietimes 
called, is largely magnesium to produce 
the intense white light of Niagara Kails. 
Also, the mixture is not rammed in the 
tube with as great a pressure as that in 
gerbs. This allows the mixture to flow 
toward the ground as it is burning. The 
Niagara piece consists of shower sticks 
strung along a rope, one plactd every 



eighteen to twent\-four inches. The 
rope is then suspended between twu 
poles so that it is twenty-five or thirt\ 
f<et above the ground. When fired, the 
showers of sparks from adjacent cascade 
pieces blend to present an unbroken w all 
of silver\- sparks.

The possibilities of the use of pre-

satisfactory, the Housing Authority 
project will be the first high-rise pie-

age and thorough knowledge of the 
mediums they employ. The observation

VICTOR SWENSON 

Many men have gone into the engi- 
neering field and found that they were 
handicapped by the lack of a proper 
college education. Victor E. Swenson, a 
senior in mechanical engineering, real- 
ized such a handicap while working for 
six years in the engineering field. In 
1947 he decided to enter the University 
of Illinois at xNavy Pier, and in 1949 
he transferred to this campus. 

Vic has been an active member in the 
student branch of ASME for the past 
three years. He was chairman of the 
Chicago Navy Pier branch in 1948 and 
1949. While he was in office, the 
ASME organized t h e Engineering 
Council; sponsored an all-L'niversity 
meeting featuring a specialist on atomic 
energy, and promoted the St. Pat's Ball. 
He was chairman of our local ASME 
exhibit in the engineering open house 
last year; and, this year he is chairman 
of programs. He is also a member of 
Phi Eta Sigma and Sigma Tau. 

Vic was born and reared on a farm 
near Belleville, Kansas. He went to 
high school in Belleville and was active 
in the dramatics club, Hi-Y, F.F.A., 
and 4-H club. He graduated in 1940 
and took an extra \ear as a post grad- 
uate. 

The suiiiuiei ot l''41, he went to 
Kansas State College at .M.uihattan, 
Kansas, to take a defense training course 
and the following fall he was a civilian

Although sunflower seed is consid- 
ered a profitable crop for midwestern 
farmers, high harvesting losses have dis- 
couraged their growth. The new har- 
vester is expected to cut losses in half. 

The machine consists of a standard 
grain combine with a harvesting attach- 
ment of gathering chains and sheet- 
metal snouts similar to those used on 
cornpickers. The chains carry the stalks 
back to a knife where they are cut off 
and dropped on the elevator canvass of 
the threshing machine. The seeds are 
then removed by the ordinary threshing 
machiner\. The snouts are used to lift 
fallen stalks into the chains.

Nathan M. Newmark, research pro- 
fessor of structural engineering, received 
the Moisseiff award from the ASCE 
last year. The award, which is given 
to the most important paper in the 
field of structural design published in 



the Transactions of the Society, was 
made for Mr. Newmark's paper, "De- 
sign of I-Beam Bridges." 

Mr. Newmark, a native of New Jer- 
sey who received his B.S. from Rutgers, 
has been with the department of civil 
engineering since 1930. Dining his grad- 
uate work at the University he served 
as a research assistant. He received his 
master's degree in 19.12, and his doc- 
torate in 1934. Upon graduation from 
the L^niversity, he was appointed to the 
staff of structural engineering. He has 
held the posts of research assistant, re- 
search assistant professor, and research 
professor, the latter advancement com- 
ing in 1943. 

During World War II, Mr. New- 
mark served with the National Defense 
Research committee and the Office of 
Scientific Research and Development. 
For a part of 1944 and 1945 he was 
in Hawaii with an operational research 
group of the OSRD. 

Professor Newmark has been a con- 
sultant on several projects in structural 
engineering and mechanics. He has also 
been associated with various military ac- 
tivities, including consultant to the 
Corps of Engineers and special pro- 
grams of the Air Force and Na\y. In 
1944 he received the James R. Croes 
medal from the ASCE.

While looking through some old is- 
sues of the 7V(7» we came across some 
jokes that caught our attention and 
thought we'd pass them on to you. 

Hack in 1921, an engineer's definition 
of a slide rule went like this: 

"A slide rule is something like- :i 
woman. It is slippery and no one e\er 
learns to manage one. It has a varict\ 
of figures which are n'.ore or le:s true. 
Men are crazy until they get one and, 
after they get it, wish they had saved 
their money. Hut unlike a woman a slide 
rule can be put in a leather case and 
shut up. " 

Fl.rSH Ylt HONEVARD 



Here is an excerpt from a l'*24 edi- 
torial which gi\es an insight nito cam- 
pus morals : 

"This semester there has been a con- 
tinual growth in the numbei of men 
who smoke on the campus. K\idently, 
there is little regard for this one dis- 
tictive tradition of our campus, and un- 
less student spirit changes at once, the 
tradition will be but a memor\. . . ." 

In 1925, this joke had them roiling 
in the aisles: 

"We present the following admoni- 
tion to freshmen; how to chink from 
fountain on third floor: 

A. Place books on floor. 

B. Apph' mouth to orifice. 

C. (Irasp hat with left hand. 

D. Press button with right hand. 

E. Have janitor wipe brains off

Perhaps you remember the poem en- 
titled "Little Ion" which we published 
last spring. Here is another bit of verse 
which, though the author is anonymous, 
appears to come from the same pen.

where cars are king 

Chrome and gadget-conscious though 
Americans may be in selecting their 
new cars, few have followed the tastes 
of .some foreign buyers. 

Autoiiiohilc Fails cited the recent 
visit of the Shah of Iran to the United 
States. Before returning to his native 
lang, he bought a turquoise-blue con- 
vertible coupe complete with radio, 
heater, spotlight, foglights, back-up 
light, license plate frames, gas-tank lock- 
ing cap, and convertible top boot and 
bag. 

By his special orders, the company 
also added an altimeter, cigar lighters 
in front and rear, a clock in the rear, 
a speedometer reading in kilometers and 
an extra set of keys. 

Another common instance occurs in 
the forbidden kingdom of Nepal in the 
heart of the highest mountains of the 
world, the Himalayas. 

The only roads exist in the central 
\alley around the capital city of Kat- 
mandu, and, although new cars are of- 
ten imported by wealthy potentates, 
getting them o\er the steep passes pre- 
sents a major problem. This, however, 
is easily solved in Eastern fashion by 
the labor of 60 to 120 coolies who 
carry a new car — wheels and bumpers 
removed for the journey — on a huge 
framework of poles on their shoulders. 

better tasting water 

An instrument known as a "dew- 
point recorder" is helping give a spring- 
water taste to water from the Schuyl- 
kill river in Philadelphia, Pa., m a new 
purification process that uses no un- 
palatable chemicals. 

Largest water purification installa- 
tion of its kind in the L'liited States, 
the new Welsbach Corporation plant 
here uses ozone, a form of oxygen, to 
kill river bacteria. The Welsbach in- 
stallation is the only one of several puri- 
fication plants here using the new meth- 
od. 

Engineers said that ozone is produced 
in the process in the same way a bolt 
of lightning produces it. The "electrical" 
odor, detectable in the air after a light- 
ning stroke, is actually the odor of 
ozone, they said. 

As the air passes o\er the metal 
plates which cause the electrical dis- 
charge, it must have a very low mois- 
ture content. To assure that the amount 
of moisture in the air remains constant 



during the process, the dewpoint re- 
corder is used. Designed and built by 
engineers of (IE, the instrument gives 
a continuous record of air dryness, ac- 
complishing this by measuring and re- 
cording the temperature at which mois- 
ture in the air condenses on a mirror's 
surface, engineers said. 

The o/.one is bubbled through river 
water from which the sediment has been 
allowed to settle. Being an unstable gas, 
the ozone breaks down again into ordi- 
nary oxygen, and in the proce.ss it kills 
the bacteria in the water. 

Finally the water is filtered and 
pumped into city mains, with only a 
trace of chlorine added to protect its 
purity from the time it leaves the reser- 
\oir, until it reaches the city's water 
faucets. 

servomechanism-kit 

A \u'\\- t\ pe se^\()mecl^anl^nl kit, 
which is capable of soKiiig complex 
automatic control device problems, yet 
can be a.ssembled as easily as a toy erec- 
tor set, has been developed for com- 
mercial use in industrial laboratories as 
well as for demonstration and experi- 
mentation in colleges and universities. 
This high-performance servo "package " 
provides a unique facility for experimen- 
tal work in industry and for the in- 
struction of servo system techniques in 
preparing graduating engineers for ad- 
vanced development work in electronic, 
television and associated industries. 

The Claude Neon servo kit solves 
one of the toughest and most expensive 
problems facing the development labora- 
tory in designing new mechanisms — 
translating the blue-print or schematic 
diagram into a working model. By pro- 
viding a number of basic high-precision 
parts, which can be experimentally as- 
sembled and reassembled where neces- 
sary on a "breadboard," the servomech- 
anism kit helps the engineer interpret 
the "rights ' and "wrongs " in equipment 
design, eliminating the need tor expen- 
sive drafting, machining and assembly 
work. 

The new unit consists of a transmit- 
ter and receiver constructed on separate 
breadboards. The servo may be operated 
as any one of three basic t>pes of servos 
by making only slight electrical changes: 
a two-speed synchro servo; a potentiom- 
eter follow-up servo; and a velocity 
servo (electro-mechanical integrator). 
Both transmitter and receiver ha\c a 
high precision fine and coane dial 
geared 36:1. The transmitting servo has 
a hand input which may be disengaged 
if a motor drive is incorporated. 

All units embody the latest in high 
performance ser\otechniques. Amplifiers 
include integral and derivative stabiliza- 
tion and the servo motor operated di- 
rectly from the plates of the amplifier 
output tubes.

How to help a gearmotor 
take care of its teeth 

To minimize wear on the teeth and to insure 
smooth, quiet operation, reduction gears in motors 
like this must be held in perfect mesh, no matter 
what the load. That's one reason why engineers 
mount the gear shafts on Timken' tapered roller 
bearings. Timken bearings hold the shafts in accu- 
rate alignment. Gears are kept perfectly positioned, 
with each tooth meshing smoothly and carrying 
its full share of the load. 



Gears mesh smoothly, 

wear longer, with shafts 

on TIMKEN' bearings 

Here is a typical gear-case countershaft showing 
a common method of mounting Timken bearings. 
Due to the line contact between the rolls and races, 
Timken bearings give the shaft maximum support. 
There's less chance of deflection under load. The 
tapered bearing design takes both radial and thrust 
loads in any combination. End-movement of the 
shaft is kept to a minimum. Gears wear longer- 
work better.
