1. The Berliner Gluehlampenwerk (PGW) c9operatpd in technical matters with
a number of East German establishments as indicated in the following paragraphs,
2. .-.The Werk fuer F, e el esen` Ob~er, ,eew_e k (OSW)~?corked closely with BGW, _
espedfally after 0 dcame a`VES establishment. Until the end of 1952,
OSW -produced the tungsten wire for its own output of a variety of types of.radio
-tubes, transmitter tubes for small and Large transmitters, Braun tubes and
television tubes, and infrared image tubes, as well as various instruments for
use In the to:ecommunications and radio industry. However, since 1953,
all tungsten wire production, beginning with,processing of the ore, has been trans
ferred to BGW along with all machinery and dquipment. Under the supervision
of BGW, production at OSW has been increased to 6.6 tons annually. Research
requirements of OSW, as revealed by its-dealings with BGW, are not known. Chips
of calcium of 99.9% purity obtained from Bitterfeld were. ubed by OSW and BGW
for gridding in the tube manufacture process. The total amount used was very small,
and a single delivery of 1/2 kg was noted.
3. EFT Fus>.kwerk, Erfurt received tungsten and other special wires produced by BGW.
~In 19, a group of scientists at RFT Erfurt succee led in producing high purity
iron powder electrolytically. It'was intended originally that this high-purity
iron powder, because of its good magnetic properties, would serve as a substitute
for carbonyl iron powder in the production of Vlipin coil cores. However, its
main use was in the production by powder metallurgy of high-purity iron wires used
in iron-by-hydrogen rgistors.l These wires were drawn at BGW,and the iron-by-
hydrogen resistors were then constructed at RFT Gluehlampenwerk,Oberta'eissbach.
The development of powder metallurgical production of these wires was undertaken
in the BGW metal research department in 1952w The resistance values of pure
iron-by-hydrogen resistors as constructed in Fast Gertnanyywere "9.5 to 9.8.
The insients were used for regulators of all kinfts and for calibrating transmitter
test oscillators. Dr. Gaulrap from Leuna was concerned with their use for'temper-
ature measurements and indicated that this subject was not to be discussed.

Ii.. The Inst tut fuer Werkstoffkunde of 'thL Teehnische Hachschule Dresden conducted
research on the prevention of recrystallization of hig11--purity iron wires.
The work was sup*iised by Prof. Dr. Eisenkolb, director of the Institute,
and Dipl. Ing. Moebius2 em'o'te -s thesis on this subject. Upon completion
of the thesis, it was taken from him and classified "SECRET". .
5.--.The Halbzeugterk Auerhammer in Aue, Ssxony,produced various semi-finished products
for*'use in the radio and vae.Cum.products industry. The quality of the output was
considered to be poor. The decision was made by the East German Government that
the Hal:bzeugwerk Auerhammer should be developed as the main producer of all
semi-finished products for the entire vacuum products and radio industry, following
the example of- iumsclnelme,Hansu. However,, since the factory was badly equtgpbdL,
the pr.erequirites for such an undertaking were lacking. Only one vacuum oven,
one high frequency s tilting oven, and a few antiquated: rolling mill trains were
available, and the labbratories were, in general, primitively furnished. The average
age of employees was between fifty-five and sixty years, since all younger people
had been made available for uranium mining in Aue, Ober- and Niederschlema. The
Mini.try of Machine Construction,3 in conjunction with other govgnlnent agencies,
ha;;4 planned a far-reaching reconstruction program for this instAllstion, tri,.i953
and 1954.
