The Koch and Sterzel plant in Dresden,, Germany,, was dismantled and shipped to 22A1

Transformatoren and Roent enwrerk VEB,
The renamed plant in Dresden was primarily
concerned with the production of equipment for reparations payment to the USSR
until 194849? Three types of medical X-ray units were produced for this purposes
a, A small, portable unit (dental type.. without rectifier) with specifications
of 75 kv at 25 ma; annual production was ' approximately. 100,
b, A medium-sized., fixed unit (without rectifier) with 100 kv transformer.
This unit operated at 80 kv and 100 ma maximum. Annual production - approxi-

o, A large-sizedunit with 100 kv transformer. This equipment
had a four-tube cascade rectifier system and operated at
80 kv and 400 ma maximum. Annual production - approximately
100.
All three types of equipment were produced complete with controls
and tables but did not include X-ray tubes. These X-ray bet,
which all had tungsten anodes, were obtained from Phoenix B, Rudol-

In August 1952 we were producing a research type of X-ray apparatus.
This equipment, which was without rectifiers, operated at 60 kv
and. 40 ma maximum; it was the usual research type of apparatus,
similar to Siemer. and Seifert machines. Phoenix molybdenum,

of the medium and smaller units we.
were used in East Germany.
2. Production of the three above-mentioned units was continued at the
plant after reparations production had been satisfied. Annual
production of the small unit increased to above 150; the medium
unit became obsolete and production of it gradually dropped from
200 per year to nearly none; the annual production of the larger
unit was still about 100 at the time of my departure More than
half of these medical X-ray units have gone to the satellite countries

but none to the USSR. China and Poland received mo.s

These two products will have standardized parts which can be
_u..se.d...interchangeably insofar as possible; all of the major
items will be interchangeable.
o. Geiger counter and amplifier
This development was planned as an internal project; three
were to be constructed for use in the X-ray laboratories
as, a protective measure for the personnel employed therein.
It was impossible to obtain Geiger tubes either from the
West or East. F Soviets provide counter
equipment for use in the uranium mining fields but we could
not obtain any of these either,
The Soviets displayed no interest in any of these three developments.,
It is anticipated that the Soviet Zone's satellite export market
will want some of these items when they become available.

theirequipment would not have sold on the Western

copie.d.from'American and German equipment but did not include the
usual complex controls., interlocks. and aq 'ety devices. The equip-

it had been very practicably designed.
