Technical data on new
synthetic insulated cables for
engineering students . . .
Our research and engineering departments have
prepared and published many technical papers
liscussing these developments and improvements.
To mention a few of these papers:
Okolite-Okoprene - neoprene-protected cables
Hazakroine Handbook - on thermoplastic
   building wires
 Okoseal thermoplastic insulation
 Neoprene Jacketed Wires and Cables
                              We will be glad
                              to mail a copy of
                              all of these papers

                (continued from page 31)
entered the Signal Corps of the United States Army in
April, 1918. While in the Signal Corps Private Glenn
Koehler was stationed at Camp Vail, New Jersey, and
carried on work in radio research and development, and
became Sergeant Koehler! Discharged (honorably) in
March, 1919, he was then employed by the Western
Union Telegraph Co. in research and development work
as a facilities engineer until February, 1920, when he
began his instructional duties as a member of the Electri-
cal Engineering Department of the University of Wis-
  Aside from his regular duties as a staff member Mr.
Koehler has spent his summers in a variety of positions
and pursuits, any one of which is calculated to keep a
person from becoming afflicted with the typical summer
do-nothing disease. For instance, during the summers of
1920-21 he was engaged in work on inductive interference
for the Wisconsin Telephone Co. as a facilities engineer.
The summers of 1922, '23, '26, '27, and '28 found Mr.
Koehler calibrating electrical instruments for the utilities
of the State of Wisconsin at the Standards Laboratory.
Subsequently during the warm months of 1929, '30, '31,
'32, and '36 Radio State WHA used his services as an
engineer and in the development of their new transmitter.
More recently (summers of 1934-37) Mr. Koehler has
been connected with Radio Station WLBL as an engineer.
We might also mention (and in fact we will!) that during
the summer of 1924 the engineering department of the
R.R. Commission of Wisconsin had a capable engi-
neer, or that research work on audio transformers was
carried on during the summer of 1927 by at least one
engineer-and so on!
  As busy as he was during these years, Mr. Koehler
found time to be married, June 15, 1922, and to raise four
children (with a little help from Mrs. Koehler, he admits).
One 18-year-old daughter is now attending the Univer-
sity of Wisconsin, while another, aged 17, is in a Madison
high school. The oldest son, 19, is enrolled in a radio
technicians' school at Naperville, Illinois, while the young-
est son, aged 6, is engaged in making home life interesting
for the Koehlers (in a hectic sort of way) as six-year-olds
are apt to do.
  Mr. Koehler has written technical articles on a variety
of subjects including the following topics: the design of
transformers for audio frequency amplifiers, audio ampli-
fiers, synchronous commutators for oscilliographs, and
field intensity meters. He is also one of the authors of
the text, Ultra High Frequency Techniques, which was
published in 1942.
  As far as his present work is concerned, Mr. Koehler
might be called the man of the hour as he is the single
teacher of six electronics courses which are designed to
give E.E. graduates 18 credits in electronics. When it is
understood that these 18 credits are the ones of most
concern to the Army and Navy, the Man Of The Hour
title is well justified, you will agree!
