Large CroWd Attends
Goodman Concert

Morethan mappreciative friends ’

of Armour Tech heard the inspiring
program rendered by the musical
clubs at their second annual Goodman
Theater Concert last Thursday night};
This large audience received more do—
light in the way of musical entertain—
ment in the three hours’ duration of
the concert than hadlvbeen es' atbd
or expected beforehand by a

All critics and reviewers 59
agreed that this performance sur‘»
passes by far that of last year, and
that allv credit for the splendid mus-
ical performance goes to the Musical
Clubs’ most able director and guide,
Mr. 0. Gordon Erickson.

New Soloistu Heard

Both the Orchestra and Glee Club
have improved greatly since last year,
having added a great many favorite
selections to their rcpertoires. The
incoming talent is also increasing
rapidly. Among the new soloists who
performed at the concert are the fol-
lowing: W. Mashinter brought from
his violin the glorious tones of
"Meditation" from Thais; M. Nys—
trom, tenor, sang “Trees” with or-
chestral accompaniment, followed by
an encore, “One Alone"; P. Woods,
oboe, played the introduction to
“Katinka” by Friml; A. Allegretti,
violinist, surprised the audience by
rising to sing the mournful interlude
of the “Song of the Bayou." .

Lighting Effects Prominent

Soloists of last year who have re—
turned to give their well-liked selec~
tions are B. Heine, accordionist, and
F. Hrachovsky, Czechoslovakian ten-
or, who sang several native folk songs.

Negro spirituals by the Glee Club
included the snappy “Ezekiel Sow dc
Wheel" and the softer, more gentle
“Goin’ Home.” During the latter

Prof. Spengl'A-Plans To
Display Models at
Columbia

 

 

As a result of the recent showing
of his models at the Palmer House
as a part of the mathematics exhibit
of the National Council of Mathe—
matics Teachers, Professor W. A.
Spencer was invited to display them
at a mathematics exhibition which is
to be held at Columbia. University
soon.

Professor Spencer’s models have
been the subject of much favorable
comment in the past, the latest of
which has arisen from his exhibition
of some sixty charts and fifteen solid
analytic geometry models.

Praised by Mathematicians

The charts showed a large number
of geometrical constructions as well
as the graphical representation of
many curves and equations. The solid
analytic models, familiar to most Ar-
mour students, consisted mostly of
hyperboloids, ellipsoids, paraboloids,
many surfaces of revolution, and
various self-explanatory string and
sphere constructions.

Shows Slight Gain

Enrollment figures for the current
semester issued by the registrar's of-
fice show the largest registration in
Armour’s history. Day school enroll»
merit now totals 846 students, as com-
paved to last semester‘s total of 825.

The freshman class, as usual, has
the greatest enrollment with a total
of 283, while the sophomore class is
second with 176. Leading all depart-
ments, the mechanicals have 151 in
their ranks while the chemicals follow
with 139. In comparison with last
year’s figures, all departments, with
the exception of engineering science
and fire protection, showed slight in-
creases, the largest being in civil en—
ginecring.

The number of sophomore coopera-
tive students in mechanical engineer-
ing is 38 while the total number of
freshman co—ops is 52.

Construction Discussed

A lecture on the construction of the
models and graphs was delivered to
the convention by Professor Spencer
in which discussion he told of his own
contributions to the methods of mak-
ing models. The processes of con»
struction and the details of workman-
ship were part of the work which
was considered the most impdi‘tant.

l

Professor Spencer‘s models are dis—
tinctive in that they are made of
bright material as compared with the
ldrab materials formerly employed.

Experimenting With Materials

Not content with his products, he is
experimenting with many new ma.
terials. Cellulose acetate of many

Solids are now being made of
plastics which may be moulded before
hardening. Previously it was the cus-
tom to use any available spherical
bodies. The flimsy cords formerly used
in modeling have now been replaced
by the stronger, more durable fishing
cords? l’rofessor Spencer has con"

Discuss Production l
Savings at A.S.M.E.'

At the last meeting of the Armour
Branch of the A.S.M.E., Paul Reh,
M.E. ‘37 and special student working
under Prof. H. P. Dutton, head of the
social science department, spoke on
“Time and Motion Study”.

Describes Motion Study

 

Describing time and motion study
as a means of increasing production
without raising production cost, he
pointed out that problems in that
field can be approached in several
ways. The first, and almost obsolete
method, is to check the motions of
the best operators with a stop watch,
noting.r the positions of the hands, ctc.,
and, the time necessary to carry out
a specific operation. Using this data,
a system eliminating the unnecessary
motions is worked out. A more mod~
urn way, which is being introduced, is
to take motion pictures of the more
efficient operators at their work; by
studying the finished picture, frame
by frame, the analyst is enabled to
study split second movements.

Two Methods Used

Itch used a problem solved by both
methods to illu‘ rate his point. The
problem consisted 01' assembling a
common wall plug and a length of
wire. Motion pictures of the origin-
al motions ol‘ assembling previous to
study, and the drawingr of the jig
which speedcd up the assembly were
shown.

At the next meeting V. J. Jandasek,
ME. ’37 and A. M. Meyer, M.E. ’37,
will speak on “Hydraulic Drives” and
“Railroad Signals”, respectively.

Inspection trips for the A. S. M. E.
Conference to be held April 19-20,
will include the Crane Co. April 19,
and the Western Electric Co., Mon-
day, April 20.

Dr. Oldenburg’ar to
Show Curve Analyzer

 

 

Dr. Rufus Oldenburgcr will con~
duct a demonstration of the har—
monic analyzer at the University of
Chicago Thursday evening, March 4,
at 7 o’clock for the benefit of his
evening school class in mathematical
analysis and interested students.

The harmonic analyzer is an in-
strument which finds an equation for
a given drawn curve when the curve
is traced by the instrument. Specifi~
cally the harmonic analyzer gives
the coefficients of a Fourier series.
If the given curve represents a sound
wave, the terms in the Fourier series
correspond to harmonics so that the
sound wave can be broken up into
components. When musical instru—
ments reproduce these components
simultaneously, the sound represent-
ed by the given curve is reproduced.

Armour students not in Dr, Olden-
burger's class, who are interested to
see the analyzer are invited to join
the class for Thursday night. The
class will meet in room 401, Social
Science Research Building, Univer‘
sity of Chicago, where Dr. Olden-
burger will demonstrate the lnstru»
inept.

Car—ops Meet, Discuss

Position as or Class

 

 

 

Questions pertaining to their stand-
ing in school were discussed by sec-
tion ”A" of the co-ops at their meet-
ing in the Mission building on last
Friday. The questions which gained
the most prominence were those rela—
tive to the standing 01' the third
semester comps with respect to the
other classes of the school, class jack-
ets, fratcrn fies, and membership in
the professional societies.

As the present, third semester men
in the co—operative course comprise
the first group of their kind, their

' a position has as yet not been
ascertained. This group of third se—
mester co~ops is scheduled to gradu-
ate with the class of ’40 yet they en-
tered with the class of ’39. In an of-
l‘ort to coordinate the two divisions of
the co—op department, the officers of
group “I3” were invited to the meet—
ing. According to the co—ops, if it is
impossible for them to make up their
minds to which class they wish to be—
long, they can at least organize
among themselves.

 

Seniors interviewed
for Job Placement

 

Realizing that the best engineer-
ing graduates must be spoken for
first, many large concerns are already
interviewing members of the class of
‘37 in co-operation with Armour‘s
personnel director. Mr. W. N. Set-
terberg.

Three General Electric Company
representatives interviewed all of the
electricals and mechanicals of the
senior class on one day and selected
five men to Whom they offered posi-
tions. If these men accept they will
be able to take advantage of a train-
ing schedule which places the men in
each department of the entire shops
for a short time.

Placement Files Inspected

The Container Corporation repre—
sentative inspected the placement files
of the class and selected twelve men
for interviews at a. later date.

The Prestolite Company man inter—
viewed fourtecn seniors, and the
Westinghouse Elevator Company in-
teivicwed all the electrical and mech-
anical engineering senior students.
Armour and Company requested ap—
plications from several senior chem-
irals while the Texas Company asked
for seven applications.

The Goodyear Company interview—
ed twenty-five men, and two l‘epre»
sentativ s of United States Steel sub-
sidiaries interviewed about seventy
students.

Other Companies to interview

Several other companies, among
them the Commonwealth Edison Com-
pany, have stated their intention of
sending representatives soon, and
about a half dozen more large com—
panies have been invited to send rep-
resentatives.

 

Class of ’39 Invites
All Professors
As Guests

When the firs strains of music
sound the opening of the Sophomore
Informal in the beautiful Oriental
Room of the Knickerbocker Hotel next
Friday night, one of the largest
crowds to attend an Armour dance is
expected to fall into step. Unique to
this dance is the open invitation to
the faculty members and administra—
tion officers to attend the affair as
guests of the class of ’39.

 

Feature Hollywood Singer

Adding to the cnamourmcnt of the
melodies of Tweet Hogan’s music, on-
tertainment will be provided by
Dorothy Skelly, as featured singer.
Miss Skelly recently arrived in Chi-
cago from Hollywood. She was em-
ployed by M—G-M and same: in several
shorts. Although it isn’t definite, so—
cial chairman B. G. Anderson, says
that perhaps Tweet Hogan will sing
some of his song novelties.

dancers. The balcony which circles
the dance floor has been provided
with chairs, and the cocktail bar at
the end of the balcony will be open,
providing refreshments.

Unique Lighting Effect

The Oriental Room is decorated in
cream color and has a glass dance
floor under which colored lights play.
The effect of the floor lights when
the top lights are dimmed is beauti—
ful.

Bids for the dance may be obtained
from B. G. Anderson and the mem-
bers of his committee: W. A. Stuhr,
I. M. Footlik, E. C. Mitchell, R. R.
Tullgren, R. I. Jaifee, W. E. Kruse,

Faculty Attends
Cornell flanquet

 

Dean llcald in company with eight
members of the Armour faculty paid
respect to Dr. Frederick Gardner
Cottrcll by attending a banquet held
in his honor last Tuesday at the-
I)rake hotel. The annual Washington
Award was presented to Dr. Cottrell
by J. R. Van Pact, president of the
Western Society of Engineers, in ap—
preciation of Dr. Cottrell’s work and
“social vision in dedicating to the
perpetuation of research the rewards
of his achievements in science and
engineering."

Famed by War Research

Dr. Cottrell will long be remem-
bered as an American chemist, met—
allurg‘ist, inventor, founder and head
of Research Associates, Inc. During
the war he was one. of the principal
directors of the research which re-
sulted in perfecting a process to re-
cover helium from oil well gases at a
cost of about ten cents per cubic
foot. Previous to that time, helium
had been a laboratory curiosity cost-
in;r $1,700 a cubic foot.

He is best known as the inventor
of the Cottrell precipitator, which,
by electrostatic attraction, cleans
gases of fine particles of dust and
dirt, saving millions of dollars on»
nually for chemical and metalluign-al
industries. He has also been one of
the chief figures behind the com-
mercial productions of fixed nitrogen
from the air.

Armour Well Represented

Had Dr. (‘ottrell chosen to com~
moi-claize his patents, the precipi—
lator alone would have made him
lwealthy, lustcid he dedicated his
work to the benefit of mankind by or-
ganizing: Research Associates to ac—
quire and administer the profits of
his patents to further scientific re‘
Search.

Armour was represented 51: the
banquet by Dean Heald, a
Dean C. A. Tibbals, and From»
Finnegan. Oldenbui‘g‘er. Penn. Poul—
tcr, Snow. ngtborg, and Zigler.
