is We of the largest firms in Czechoslovakia. It produces a11-
types of low-voltage equipment, radio sets, radio tubestand
electric bulbs. The main offices are in the former Phillips
buiLding on Karlovo namesti, Prague (051/L 78 L88).
Adroinistratively the firm is divided into two main departments,
Production and Development.
2, 'Me Production Department is divided into branches each of
'which is headed by a branch manager who controls the planning
and selling phases of his branch. Production at Tesla is part
of the Five-Year Plant and according to published reports has
reached 100 percent of its target. The quality of the finished
products, however, is not good.
Shortages of materials are creating bottlenecks in production.
There is a great shortage in colored metals, but the greatest
lack is in special high quality alloys used in making transformer
sheets, and circular cores for coils. German msteriall left
over from the reserves of the Siemens company, is still being
used but will soon be exhausted. Permalloy is in short supply,
but the Czechoslovak Metallurgical Works are experimenting to
see whether it can be produced in Czechoslovakia. So far the
results have been negative. England is the main source of
permalloy and if she discontinued exporting this alloy to
Czechoslovakia it is doubtful that production of transformer
sheets and coils could be continued.
4. The Development Department, with central offices in the
Mikrofona buildings at Prague-Strasnice? is. the technical
brains of the corporation. Laboratories are located in the

constructed, and tested* A large staff of engineers and
technicians have at their disposal a vast library culled
from western sources % and the research files of the former
Siemens company* The Siemens archives contain data for the
production and design of transmitters* transformers, coils,
measuring instruments;and transmitter stations* As a result
of this body of technical information available to the Tegla
company, Tesla production is based mainly on Siemens products*
The Development Department consists of five divisions:
Physical research division, which works on theoretical
mathematical and Physical problems*
Receivers division, where receivers, especially for
aircraft, are constructed
Transmitter division, where research on theoretical
and practical problems of ultra-short waves is done*

devices already developed by the Tesla Development Department:
A device has been develbped to tap telephone calls and: -
to transcribe the conversations on records* As many as
20 calls at a time can be recorded on two discs. This
machine is an exact copy of one developed by Siemens*
b. Communication by means of a coaxial cable is being studied*
A plan has been conceived to construct a magistral across
all of Czechoslovakia, but the research on this project
has just begun. 1i-top-LIP tRepeitemer stations will have
to be built along the route*
A network making use of a carrier system (Standard type
SOJ 12, Siemens MG 15 and BOA 12) is to be built in
Bohemia and Moravia with connections leading into all
of the town networks* Dialing of long-distance telephone
calls will be possible*
At Pardubice, Tesla engineers :are trying to improve the
French-type ultra-short wave equipment* Test equipment
is being Used between the Sending .station on the Petrih
hill in Prague and a receiving station on the Snezka
mountain (P50/N 26) in the Krkonose Mountains* The
telephone. systems of Prague and Trutnov (051/G 74) have
been connected to this netiand dialing is automatic
between these two points, It is planned to extend this
net into Poland.;

25X1X is working on aircraft landing equip-
ment-, but his progress has been so slow that production
will not be started until 1951.
f. Work is going forward on a sending and receiving set for
communication betWeen aircraft. The set is called
"skrivanek" (nightingale).
