K. LaMer of the Columbia Univer
sity Department of Chemistry ad
dressed the A. & M. Section of the
American Chemical Society Sat
urday night.
Illustrating his talk with dem
onstrations, he discussed the Tyn
dall effect as a means for rapid
determination of particle size in
smokes and colloids.
Dr. LaMer has been connected
with Columbia University since
1919 in the Department of Chem
istry and has been a visiting pro
fessor at Northwestern University,
Stanford University, and Pennsy
lvania State Colleg.

called “secret files” (“They are
not particularly secret/’ Walton
remarked) the former president
quoted Dean Potter as recommend
ing “Unless you have a million
dollars, don’t spend more than
$25,000 on a wind-tunnel. All you
can build is a toy, and you’ll be
wasting the taxpayers money.”
Hardeman charged that this rec
ommendation was hidden at a time
that it should have been brought
out; namely, when the legislature
was considering the bill by which
it appropriated $60,000 of the
$100,000 cost. The tunnel has nev
er been completed.
★
F. C. Bolton, dean of the college,
gave the committee figures show
ing that a disproportionate num
ber of cadet freshmen had left
school last year, and then stated
that in 75 cases hazing had been
blamed, directly or indirectly. The
investigating committee asked for
names so that some of the departed
fish might be asked to testify.
Answering inquiries about the
chemical science course and the
Veterinary Medicine school, Dean
Bolton stated that the chemistry
course had been dropped from the
approved list because the faculty
was not doing enough research to
satisfy the one-man inspecting
party. No loss of quality in gen
eral chemical instruction was indi
cated, Bolton said, and there is no
reason to believe that A. & M. is
greatly different in this respect
from many other schools.
As for the Veterinary Medicine
school, Bolton pointed out that it
is still on the approved list.
Asked about the faculty panel
trial proposed for Clyde Cecil, on
grounds of presiding at an unap
proved meeting, (the senior class
meeting which voted “no confi
dence” in Ed Brandt and Jack Nel
son) Bolton stated that the case
had been dropped and there was no
indication of the charge on Cecil’s
records.
Bolton presented to the commit
tee photostatic copies of the schol
astic records of all officers of the
Veteran Students Association,
showing that only Sam S. Wil
liams had ever been up for discip
linary action (hazing, in 1941).
Holzmann’s Figures
W. H. Holzmann, comptroller of
the college, introduced figures
showing that the cost to the tax
payers of the Dean of Men’s of
fice and commandant’s office com
bined was about $35,000 a year,
rather than the $100,000 allegedly
alleged. That figure would be
$23,000 more than for the com
mandant alone.

night at 7 p.m. in the northeast
corner room of the Animal. Hus
bandry pavilion.
Final plans for the annual bar
becue will be made at the meeting.
The barbecue will take place at
the Hensel Park Saturday after
noon, April 19, at 5 p.m. The
park is located just north of the
landscape nursery past the circle
on the road to Bryan.
Anyone planning to attend the
barbecue who cannot be present at
the meeting should contact the sec
retary in the Horticulture office by
Wednesday in order that an ac

A&M Model Aviation
Club to Reorganize
Aggie model airplane enthusi
asts will re-organize the A. & M.
College Model Aviation Club at
7 p.m. Wednesday, April 16, in
Room 108, Mechanical Engineering
Shops building.
Older modelers will remember
the pre-war club as primarily a
group of free-flight model enthu
siasts; however, it is expected that
all phases of the hobby will be in
corporated in the new organization.
Regular “flying sessions” club con
tests, and a number of technical!
and scientific discussions are sched
uled for the spring agenda.
Rogers L. Barton, faculty ad
visor, has indicated that the spon
soring Industrial Education De
partment will cooperate to develop
this club into the most active or
ganization of its type in this area.
All model enthusiasts, regardless
of whether they have models at the
present time, are invited to be pres
ent Wednesday evening.
Need for Workers
With Merit System
The need for qualified workers
in the state agencies served by the
Merit System Council continues to
exist. Through the medium of mer
it examinations administered by
the Merit System, returning vete
rans, along with others who may
be seeking employment, are offer
ed an opportunity to secure em
ployment in state service.
Dr. A. A. Jakkula and W. L. Pen-
berthy, who had certified, under
notary seal, that 179 signatures
were on the original petition held
in Jakkula’s office, from among
the 440 members of the faculty.
About two dozen signatures were
on another petition, from which
one paragraph has been removed.

Research Problems in the Manufacture of Nylon
WANTED: Large completely equipped
house trailer. Late model. 607 Fairview,
South Gate or write Box 4347.
Last month in this space the develop
ment of nylon was traced from a funda
mental research study on linear polymers
to the first synthetic organic fibers, the
superpolyamides. This installment deals
with the complex manufacturing re
search problems that followed.
From the start there were obstacles
to the production on a commercial scale
of the ”66” polymer—so named because
the adipic acid aiad hexamethylenedia-
mine from which it is made have six
carbon atoms each.
Although adipic acid was being pro
duced in Germany, it was necessary to
develop a new process to meet conditions
at Du Font’s Belle,W.Va., plant, where,
because of the catalytic technique in
volved, it was decided to make this
intermediate. Hexamethylenediamine
was only a laboratory curiosity, and a
process for its commercial production
had likewise to be worked out. Fortu
nately it was found that the diamine
could be made from adipic acid by new
catalytic processes. The results of these
investigations may be summarized as
follows:

A Nylon Polymer
The synthesis of intermediates was
only part of the problem. Nylon poly
mer was an entirely new material with
properties different from any previous
synthetic product. It provided the first
example of spinning fiber from a molten
polymer (m.p.263°C) and required en
tirely different techniques from rayon
spinning. Information was acquired
only by painstaking experimentation at
each step.
Manufacturing Process Outlined
The process as finally developed for the
manufacture of nylon and its fabrica
tion into yarn may be briefly outlined
as follows:
Nylon salt is heated in an autoclave
with addition of stabilizers to control

molecular weight and viscosity. A lonj
chain linear polymer is formed with
molecular weight of 10,000 or higher.
The melt is converted to solid chi;
that are later re-melted and extrude
through a spinneret to form filamen
at a speed of 2,500 feet a minute. T1
filaments are then drawn out to aboi
four times their original length in ord<
to develop the desired textile qualitk
characteristic of nylon.
These operations sound simp]
enough, but some of the problems ei
countered were extraordinarily difficul
For example, a specially designed gri
for melting the polymer was necessai
because of the poor thermal conducts
ity of the polymer; pumps had to ope:
ate at 285°C with only polymer as
lubricant; special abrasion-resistar
steels that did not soften or warp g
285°C were necessary; the spinning a <
sembling required radically new eng
neering developments to produce th
necessary fiber qualities.
All of these chemical, physical an
mechanical engineering problems ha
to be solved and dove-tailed into a un
fied process before manufacture of nj
Ion could be undertaken. In all, abou
230 technical men and eight manufac
turing and staff departments share th
credit for making nylon the importan
part of American life it is today.
