1. The Hungarian national factory 'RSntgen is Orvosi Keszalikek Oysra"
(X-Ray Apparatus and Medical Lquipasnt Factory) manufactures various
kinds of X-ray apparatus which are exported in large quantity to
Turkey and the fear Bast. orders frequently can be filled only after
tong delays, because factory production is hssipered by shortages of
.raw,materials. Since metals for X-ray apparatus no longer can be
procured abroad, the factory has been obliged since the spring of 1953
to make the casing of the 2-6 KV X-ray tube itself, from domestic raw
materials. Consipuentc of -ray apparatus?parte amounting in value
to over b million forint;;have been required. The tteppage of deliveries
from abroad has caused a great deal of trouble.
2. ' +turther difficulties in the :-=facture of tebting apparatus arise
because not enough ball bearin{;e can be had. In order to carry on
production of the various -;'ay apparatus ist'lbw circumstances, it has
been necesaHry for son.: month:; to use ~ubstitultes which have not been tried

Much more important than the trade in medical X-ray apparatus however
13 the exportation of portable X-ray apparatus for testing the structure
of metals in heavy industry and war materials production. The factory
makes several kinds of such testing apparatus. In Hungary the "Mobil M'
apparatus is used not only in the metallurgical industries, but also In
the ceramic industry for testing the big insulators for high-voltage current,
for safety fuses and cables.
5. Thts testing equipment is manufactured in four models: M2, M3, M4 and
M4 Special. All four are exported.
6. The "Mobil M2" apparatus consists of three units. It is a single tank-
half wave apparatus. The power output of the ''M2" and "M3` apparatus
amounts to 15 mA with a maxvnma ,a, of 250 kV, or as the case may be,
30 mA with 100 kV; between 130 and 170 kV, 20 W. The 1im++-? of thickness
of materials for attainable reception Si 7 are also the same with both models:
for copper, 70 mm; iron, 100 mm; aluminum, 4vu mm. the dccua.l praceical
limits of the apparatus naturally depend also on other factors, such as
the alloying of the metal.
7. The three units of the "Mobil M2" are the common grounded single-tank body
for high voltage transformer ai.d X-ray tube, the switchboard, and the cooling
pump. Accessory items are the flexible armored tube and cooling-oil pipes.
8. The shaft journal of the tank is attached with ball bearings to the
supporting post of the truck, which is provided with spiral steel springs.
The arrangement of the steering-wheel-like worm gear makes it possible for
the tank to be rotated through the longitudinal-running vertical plane.
The high voltage transformer is in the lower and larger part of the tank, which
also contains the filament transformer for actuating the hot cathode of
the X-ray tube. The upper and smaller part of the tank contains the X-ray
tube. The sensitive tube is enclosed in a metal cylinder open at both
ends with a 6 sum, lA" thick le,. lining, the so-called potential cylinder.
There are cooling coils in both impartments, supplying cooling oil to the
X-ray tube.
9. Exhausted tubes are easily and quickly changed. The rollable switchboard
is a metal covered, iron bound box. The controls for the entire apparatus
are located on the cover plift6 the measuring instruments, the setting
devices and the operating switch. The synchronous motor-time switch for
setting the time of exposure works automatically. The operating switch
starts the cooling motor;' the various circuits are all controlled by a
single switch. The voltage of the X-ray tube can be adjusted continuously
from about 80 to 260 W. The apparatus is protected from dust and dirt
10. The jackoted radiator coil is a modern technical device. The tubkgerun
into the lower, cylindrical-shaped oil tank of the cooling motor. The
warmed oil runs back into the tank through the inner tube while the coefl ng
water circulates through the outer tube. The right oil level is high
enough so that the:rooIJng pipes are covered.
11. The "Mobil k3" apparatus consists!'of six units and s a more modern type
than the M2. The switchboard and oil ouirp are the saolr: as in the X2. The
outstanding difference is that in the 103 the X-ray tube is mounted in an
independent hood and carried on a separate support. The transforr,.or is in
two halves and therefore more easily transportable. The connection between the
 Approved For Release 2006/09/28: CIA-RDP80-00809AO00500810339-3
two poles and the anode and cathode-side transformers is bj means of
flexible, voltage-fuse-protected rubber cables. The 1!3 a;rperatus is
,.more mobile and more easily transportable than the 1l2. The oil chamber
of the.anode transformer contains a high voltage condenser, a valve tube
and a protective resistance bleeder for the X-ray tube. Ve various
parts can be changed quickly and easily.
12: The two.apparatus.are quite'different in outward'appearanoe. The X-ray
tube support of the M3 is movable. The protective cover can be slid in
various directions.. 14m cover is protected, against radiation and contact.
It is connected'with the two transformers by a high voltage rubber cable
and.with the.cooler'by oil, fpes. The time of exposure is specified by
diagrams. F

13. The '.'M3.. :and "M4 Speoda}";models are"for testing cylindrically-shaped
material. -These lodels -are still more,,mnobile. Both are of-single
transformer construction. The X-ray tubes are tnipolar. 'They'are'
inexpensive. They can also be used for such materials as are not accessible
to.bipaler.tubes on account-of their shape. The second pole is grounded.
2 The ~h* Special" radiates circularly and is only suitable for rapid
testing :or cylindrical-specimens. The all-around picture coverage
exposes material defects it all points'of the sample being tested.
14. The '"Mobil M4" has a lateral-radiating unipo,ar tube and allows the
testing,by transillunination'of special-shaped pieces.
