rectifier plant was separa a rom the
electric works a sma er p an , ch actuall was the
rectifier plant9 employed 154~.workers9, of which ~4~ were forced
labor, 30~ women, 1?~ unskilled lab?r, 10~ semis-skilled laborm
and 10~ skilled labor. fJnly single anode rectifiers assembled in
blocks of six were manufactured there, copied f r+~m _ ~nericar~ -
models, These rectifiers were used for railroad installat~.ons
and electrolytic systems especially for aluminum electrolysis,
and did not represent anything new in known technicalrfieids.,
With the exception of modern grid control mechanisms which were
developed by Dr Ernst Ludwig on the basis of Siemens diagrams9 no
new production was undertakenp
2. The general condition of the factory gave an impression of ca-~
tast~ophea Installations to insure the proper assembly of
rectifiers were not available, and were manufactured in part
at the beginning of my activities there. There- was an acute
shortage of the most necessary tools, such as hammers9 pliers;
files, vises, etcs The few workers who had- their awn tools had`?
to guard .them carefully, and sometimes even carried tkaem with
them9 attached on strings, G_enerallyA wrendhes or stones were
used in place of ha~un,ers a
The general production procedure was dictated. completely by a
plan9 which had to be approved in-every detail. by Moscow,, .Since
material could be procured only after the plan had been approved9
actual-manufacture was begun weeks or months late and e
hastily serf?rmed in order to meet deadlines.
