REACTION GOES AWRY

 

Maynard Venema has again rc-
vcalcd those hitherto unsoundco
depths of technique which won for
him the unanimous election to the
exalted ranks of Schmier—Chcmiker
last week.

While it is dvscouraging to view
this concentration of talent in one
individual, a man who can repeat
that which others can hope to do only
once, his cloud is one which has a
silver lining. If any doubt existed
about Venema’s eligibility for last
week’s award, the sulfonation affair
of last Monday has removed any fore-
loadings.

Speaking of clouds, however, at
once brings memories of the Indus-
trial Lab ceiling. Painting a cloud
is “' of an. " ‘ ‘
for even the most skillful artist;
painting a cloud on a ceiling must be
harder yet. Venema. claims that it
takes practically no time and very
little effort. Anybody who can point
to his achievement with justifiable
pride the way he can, is entitled to
speak with authority, for his is truly
the work of a master.

Of course, this sort of thing can
be overdone, especially in view of
the high costs of interior decoration,
since chemicals, unlike oil paints,
have the unhappy faculty of chang—
ing color with time. For this, and
other reasons, the appearance etymor‘e
and bigger clouds on laboratory ceil—
ings may be frowned upon by the
custodian of the bankroll.

On this account we suggest that
future aspirants to the exalted
brotherhood refrain from such violent
and colorful demonstrations to prove
their worth.

After all, a cloud of smoke or a.
minor blaze is just as full of. possi-
bilities for excitement and under the
right conditions, easier on the sur-
roundngs.

Rather, who also won the cherished
honor last week, seems to be highly
exhausted from his efforts and is at
present recovering from that tired
feeling by seizing judicious and very
beneficial naps in Professor Carpen—
ter’s metallurg‘ class.

 

 

Professor Bible is
Rapidly Recovering

 

Professor Bibb, of the mathemate
ics department, underwent a thyroid
gland operation on Monday, October
26.

He has been absent from school
because of illness since the begin-

rapid recovery after the operation.
Anyone who wishes to see him and
cheer him up will find him convales-
eing at the Woodlawn Hospital,
Sixty—first Street and Drexel Boule-
val-(l.

It is hoped that he will recover
sufficiently to return to school and
resume his teaching some time be—
fore Christmas.

 

Belt Representative

To Speak More Friday .

Through the courtesy of the Illi-
nois Bell Telephone company, a rep
resentative of the American Tele-
phone and Telegraph company has
been obtained to speak at the meet—
ing of the Armour branch of the

 

 

A. I. E. E. to be held Friday at
10:20 in D-Mission.

The intricacies of the telephoto
system will be explained in the talk.
The name telephoto applies to the
transmission of photographs by
wire, and the service includes also
the sending and receiving of fac-
similies of such things as important
documents, checks, fingerprints, and
photographs.

Chemicals Visit
New Coke Plant

An inspection trip to the Coke plant
of the Youngstown Sheet and Tube
Company at East Chicago, Indiana,
occupied the afternoon for the senior
chemicals last Tuesday, October 27.

In the process of obtaining coke
from coal, numerous other industrial
products are obtained, such as coal
gas, ammonia, benzol, toluol, creosote,
and pitch. The coke is manufactured
for use in the main plant where iron
is obtained from its ores.

The most impressive sight on the
trip was the large and powerful ele-
vator, which lifts a car containing
100 tons of coal every three and one»
half minutes and dumps the coal into
large bins.

This coal is taken to the distilleries
where all volatile matter is removed.
The four fractions obtained from the
first distillation are coke, coal tar,
coal gas, and ammonia liquor.

The latter three fractions are brok-
en up into the constituent chemicals.
Creosote and pitch are obtained from
the coal tar, phenol and ammonia
from the ammonia liquor, and phenol
and toluol from the coal gas. The
waste heat from the ovens is used in
the " "‘ " of the coal tar.

A new plant has been installed re-
cently to recover the chemicals pres-
ent in the ammonia liquor.

 

Ogden Avenue Bridge
inspected by Civils

 

The Ogden Avenue Improvement
was the scene of an inspection trip
by the Senior, Junior and Sopho-
more Civil students lasts Friday.

The students met at Division and
Halsted streets at 1:00 P. M. Pro-
fessors Wells, Ensz, Grafton, and
Jacobson» were the, faculty members
that were present.

The Improvement is being con-
structed by the Ogden Avenue Con-
struction Company. Mr. Langdon
C. Hardwicke, who is Superintendent
of Construction, graduated in the
Civil Department of Armour in
1924.

The portion of the Ogden Avenue
Improvement now being constructed
forms the last link in the improve-
ment and connects up the two com-
pleted portions which extend from
Lincoln Park at Clark and Center
Streets to Division and Halstcd
Streets and from Randolph Street
to Chicago Avenue. This portion is
two-thirds of a mile in length and
extends from the right<ol'-way line
of the Chicago and North Western
R. R. to the west street line of Rees
Street. It will eliminate two street
car crossings, the grade crossing of
thirteen railroad tracks; separate
the traffic on Ogden Avenue from
that on North Halsted Street and
through-routing Ogden Avenue
through one of the busiest industrial
sections of the city.

The improvement crosses the
North Branch of the Chicago River
by means of a two-leaf trunnion
bascule bridge. In designing this
bridge it was necessary to use three
railing height trusses in each leaf,
thereby permitting a reduction in the
depth of the floor beams. This re-
duction was necessary in order to

Professor Spears
Lectures to W'. S. E.

A meeting of the Western Society
of Engineers was held last Friday
at 10:30 a. m., in B. Mission.

Professor Spears delivered the
lecture. His topic concerned the
building of a hunger for the “Ak»
ron,” the navy’s newest and largest
dirigible.

Because of the great size of the
dirigible, some interesting problems
in the design and construction of
the hanger were encountered. The
hangar is built up of parabolic
arches. In the preliminary con»
struction the three—hinged arch is
employed but it is finally built up
into an arch of two hinges by the
introduction of permanent upper
and lower chord members at the top
hinge.

 

 

 

Armour Institute of Technology, Chicago, Illinois

Processor season 1 Warther Display

MAKES TESTS 0N
NEW lNS’l‘lilllWhN’i‘

A new device for determining the.
completeness of combution in gas
engines is now on exhibition in the
Automotive Laboratory and is being
tried by Professor Roesch and his
senior mechanicals This indicator,
developed in the last two years, is
called the Casam~instrument. It has
already been put to good use by
Captain Hawks in some of his rca‘
cent record-breaking flights. Its
merit lies in its permitting the most.
economical setting of the carburetor
by observing when the combustion
etficiency approaches 100 per cent.

Briefly, this efficiency is deter»
mined by passing a sample of the ex.-
haust gases, mixed with a consid-
erable amount of air, over the two
arms of a Wheatstone Bridge. One
of these arms is arranged to act as a
catalyst to cause the unburnt gases
to burn at a lower temperature. The
additional heat produced renders an
unbalanced circuit in the Wheatstone
Bridge thereby deflecting a galvan-
ometer. ,

When there is no combustible mav-
terial in the exhaust gases, the two
arms of the bridge are equally heated
and the scale of the galvanometer is
marked 100 per cent. Most gas on-
gincs, however, show some unburnt
or partially burnt gases in the ex~
haust such as CO, CH‘, and other:
hydrocarbons unless mixtures are so
loan that starting is difficult. ‘

Practical ratings for automobile
engines are 85 per cent combustion
efficiency as indicated by this irr—
strument. Captain l-Iawks was
able to adjust the carburetor from
the pilot seat and so maintain the
heat mileage or maximum power
from the gasolene.

 

  

See Water Softening
and Treating Plant

 

As one of a series of inspection
trips planned by Protessor Bentley,
the junior chemicals visited the I'Iins-
dale Water Softening Plant last
Thursday, October 22, from 2:00 to
4:00 P. M.

This plant, which is one of the most
up to date water treating plants in
the United States, was finished in
1925. It was completed in a year
and one half at a cost of 175,000 dolv
lars.

The region including and surround-
ing i'linsdalc abounds in limestone
deposits, and hence the well water
is very hard. This water caused
trouble in steam generating plants,
such as are in most homes, by the
precipitation of various dissolved
chemicals which clogged up pipes and
reduced the efficiency of boilers.
These troubles are eliminated by the
present water softening plant.

The efficiency of the plant is un—
questionably high in the matter of
removing undesirable chemicals.

It is properly spoken of through-
out the country as the “one man
plant.” W. P. Case is in charge of
all operations, his official titles be-
ing Foreman, Chemist, Head of
Maintenance Department, etc.

The only operation in the treat-

Christmas Concert
Program Planned

At the last meeting of the Glee
Club the newly elected officers as—
sumed their duties in full force.

As an inspiration to the more or
less irregular members, the fact
might be mentioned that the direc-
tor, Dr. Protheroe, has been late for
rehearsal only once in his six or soy--
on years of service. This note-
worthy event occurred last week,
when he was five minutes late for
rehearsal.

The probable date of the winter
concert is set for about December
17th. Among the numbers sung at
this time will be: “The Song of the
Jolly Roger”, “A Song of Ships",
“Jolly Fellows”, and “A Little Close
Harmony”.

 

oi Models Here

Dean John C. Penn has recom-
mended seeing the Warthcr Coller
tion that is now on exhibition at the
Sherman Hotel. The collection con-
sists of every model of locomotive
from the very first to the latest type
of heavy mountain design. Ebony,
ivory, and abalone shell were used
in the carving of these unusual
models.

Ernest Warther, an American of
Swiss descent, made the locomotives
from sketches and blueprints that he
was able to procure.

Many of the models that are us-
ually seen at exhibits of this nature
are merely models from the stand-
point of appearance. Those in this
collection however, are true in every
detail, even down to the tiny bolts
and nuts which have actual threads
and screwdriver slo‘s.

All movable parts on the originals
have been made movable in the mod-
els. This results in giving the cxm
hibits a very finished and realistic
appearance. Since the parts were
made to specifications taken from
scale drawings, all proportions have
been preserved to a scale of one half
inch for one foot.

The range of locomotive models
includes about twenty—five units and
is in itself an eloquent history of the
progress in mechanical engineering
which has given us a great modern
convenience.

While the early types were built
chiefly to satisfy given load condi~
. us without breaking down in serv-
ice, the most recent developments in
engineering have made it possible to
get other desirable features. Among
these are the high efficiency and
speeds characterizing the passenger
trains operating on through schedules
between distant cities.

To read a history lif‘tn'oi’lroadi‘ng‘
from the very beginning would take
considerable time, more time, per-
haps, then we can very well spare.
However, the subject is too inter~
esting to pass by and the opportun—
ity offered is one that may not be
repeated in the near future.

A. l. Ch. E. Will Hold
Meeting This Friday

Students in the department of
chemical engineering will hear a
lecture on the crushing- and sampling
of ores, at a regular meeting of the
A. I. Ch. E. to be held this Friday,
November 6, at 10:30 in the Physics
Lecture Room.

The lecture promises to be an in~
tel-eating one and is to be given by
a representative of the Raymond
Brothers Impact Pulvei'izing Com-
pany.

Speakers for meetings, which are
held every two weeks, are obtained
by correspondence with many in-
dustrial organizations. At present
an attempt is being made to secure
R. B. Harper of the Peoples Gas
Light and Coke Company to lecture
on the World’s Fair Exposition to be
held at Chicago in 1933.

Students in other branches of
engineering are invited to attend the
various meetings.

Annual Banquet

’lhc annual banquet ol, the Hanoi
"A’ Society will he held December
I, after the Varsity-Alumni basket~
ball game. This was decided at a
meeting held last Friday, but the
place has not been chosen definitely,
except that it will be held at one of
the campus fraternity houses.

An election of a secretary was held
and of the two candidates, E. Sade-
man and It. Carlsti-om, the latter was
elected.

Bids to membership are being ex-
tended to a number of upperclassmen
who have been active in sports.

H. C. Rossing is president of the
society, and I“. A. Ustryski is vice
president.

society Founded in 1914

The Honor “A" Society was found~
ed in the spring of 1914 and is one
of the oldest existing organizations
at Armour. It was organized origi—
nally as the governing body of ath—
letics at Armour, being supplanted in
that capacity by the Armour Tech
Athletic Association. It now exists
as a society to promote athletics and
to bind the letter men together. As
a mark of disinction on the campus
the members wear small gold “A"
charms, a star being engraved for
each sport award.

City Papers Await
Adorning of Fresh

Interest in freshman hats has
now risen to such a point that be—
fore long actual specimens may be
seen and appreciated on our campus.

The upper classes have been thor-
oughly canvassed and the majority
seem cpthusiae about, the “plan.
The facts at hand indicate that most
of the freshmen are not opposed to
the idea of wearing skull caps. They
realize that such an increase in col‘
legiatc atmosphere would be very de-
sirable. Since skull caps .are so com-
mon at other schools, the adoption
of such a distinguishing mark would
achieve the desired result without
subjecting the freshmen to the ig-
nominy of the more revolutionary
Eugenics.

 

 

Dailies Getting Anxious

This venture is attracting almost
as much interest outside of school
as it is in. Recently a photographer
from the Evening American hurried
to school to take pictures of the hat-
ting event but was disappointed.
Last Wednesday. a Herald and
Examiner representative telephoned
the school officials and asked to be
informed of the developments of the
idea.

The committee, in charge of this
work, consisting of J. R. Jackson,
.lr., J. R. Fernbach, and J. L. Lynch
of the senior, junior and sophomore
classes respectively, is of the opin-
ion that the time honored skull caps
are more appropriate for Armour
than the recent Eugenie style.

 

Freshmen Breaks Arm
In Gymnasium Mishap

Mitchell Dojnick, ’35, fractured
his arm last Monday between 10:30
and 11:30 while participating in a
basketball game in the school gym—
nasium.

Playing the position of forward,
Dojnick dribbled the bull down the
floor with a burst of speed. in some
manner he collided with two other
players and was hurled toward the
wall. In order to check himself, be
extended his right arm. but crashed
with such impact that the arm was
broken.

He was taken to Mercy Hospital
by Dean Penn, where Dr. J. F. Mew
Namnra, the Institute‘s medical ad-
viser, administered first aid, and set
the fractured arm. It is expected
that Dojnick will return to his
classes some time this week.

Jackets on Exhibition
in Trophy Case
Today

PRlCES REDUCED

Four of the senior class com-
mittees have started the work for
which they were formed and will
announce the results of their activ—
ity in the near future.

The jacket committee has visited
seven companies and has finally de‘
cided upon the firm of Rexford and
Keltler. This firm manufactures
senior jackets for Northwestern Uni-
versity, and the Universities of Mich—
igan and Wisconsin. Their price is
more reasonable than that. paid in
former years. Seniors may obtain
jackets this year at $7.50, a saving
of one dollar.

It is planned to have a sample
jacket on exhibition today in the
trophy case, on the first floor of the
main building. In the near future a
man will be sent to the Institute by
the company to measure those who
wish to order jackets.

The following men compose the
committee:

T. A. McGill, chairman.
V. R. Candberg.

L. G. Wilkie.

J. Palma.

R. E. Long.

The photograph committee, work—
ing in conjunction with the Cycle

Uramatic Club Holds
First Meeting Nov. 5

 

There will be a meeting of the
Dramatic Club, which is in the
process of being formed at Armour,
next Friday, Nov. 6, in the Tau
Beta Pi rooms from 5 to 0 o’clock.

The rooms are located on the
third floor, first entrance lof Chopin
Hall. To date about twenty-five
men have signified their intention
of joining the club. The prospec—
tive members are equally propor~
tioned between all the departments
of engineering, and in view of this
fact the drama club should be a
success from the technical stand~
point.

Among the business to be taken.
up will be the choosing of an 31:»
propriate name for the organization.
A mysterious name or one which
must be looked up in the dictionary
for the meaning is wanted. Anyone
with ideas on the subject please ex»
press them to the committee in
charge. There will also be an elec-
tion of officers so as to get the club
organized and in working order as
soon as possible.

The object of the. Dramatic Club
is to furnish entertainment in the
form of one act plays at any of the
various smokers or meetings of the
student body, where such entertain-
ment is needed.
