A-EZILIRACT: Theoretical and experimental data regarding current amplification an'
input and output impedance of various types of the transistors in the low-temeraturel;l
ranges are considered. An experimental liquid nitrogen refrigeration chamber is de-
scribed; this chamber keeps the temperature of the medium within the low temperature
range., do-,m to -160C, with deviations not exceeding 4- 2C. The aim of the study was
to fill the existing gap in the theoretical and exp4_rimental data on the lo-w-frequen-
cy operation of germanium transistors in the low-temperature range down to -140C.
Graphs and data presented in the original article on temperature dependences of tran-
sistor electric parameters are based on measurement results from 10--40 transistors
of each type tested. Orig. art. has: 14 figures,, 1 table, and 23 formulas. CKPI

ABSTRACT: The instrumeriL Is designed to measure ray velocities and the profile
of the Fice line in the spectrum of any formation on the solar limb during its evolu-
tion. The output of the spectrograph is rigidly fitted with a photomultiplier using
a searching guide. The guide is fixed in such a way that the HY line of the III
order is in the field of the ocular micrometer, when the Ha line of the H order
reaches the photomultiplier. Following a rearrangement of the guide, the instru-
ment may be used to register other lines. The output slot is 511 x 0. 07 A, the
dark current of the photomultiplier is 10-9 at a voltage of 1880 v. Use is made of

TEXT: A Markov type microphotometer was assembled at the Main astronomical observatory of the AS
Ukr SSR. The mechanical part of the instrument was made according to the observatory drawings at the
Physics institute of the AS Ukr SSR. This part and to a considerable extent the optical one were adopted
from the double spectro jector. The photometer is mounted on two plates connected together by four stand.
A screen with an opening on the optical axis of the objectives is fixed to the lower plate. The opening in the-
screen is covered by a disc with a set of circular diaphragms of 19.0-1.7 mm diameters. The (D9Y-22 (FEU-22)
pboto-multiplier is placed under the screen. The stage which is moved by a vernier is placed on the upper
plate. The light ray is collectcd by a condenser and the objective on the photometered area of the plate.
This area is focused by the objective to the screen. A Fabri lens is placed in front of the phOLOMUlEiplier to
focus the image of the objective on its cathode. The recording part of the photometer consists of an illumi-
nator, a 173C-47 (GZS-47) galvanometer and a reading scale. Results of tests on the instrument operation

ABSTRACT: A study is made of the possibility of separating La3+, Pr3+, and
Nd3+, adsorbed on the ammonia form of the cation exchanger KU--Z,
by eluting solutions of complex acids of Mg2+, Zn2+, CdZ+, and
Hg2+ with H4 Ent'a. Experiments showed the pH of these complexes
to provide no accurate and precise answer, for practical purposes,
to the question of the processes whereby cation exchanger KU--2
separates the rare-earth elements. It is established that a solution

Pr and Nd, but less effectively than does a Zn complex. A solution of the Hg

ABSTRACT: Type PR and PRG rubber -insulated cotton-braided conductors are
used for making connections and leads in electric machinery and equipment
with class A insulation. In wiring work, conductor ends are additionally
insulated for fixing the braiding edges and protection of rubber insulation.
Varnished -cambric tape is conventionally used for this purpose with subsequent
application of a parachute thread. At thq KhEMZ factory, it was suggested that
the varnished cambric be replaced by a p9lyvinyl -chloride tape as manufactured
by the Ministry of Chemical Industry from specifications TU 2898-52. The

ABSTILICT: The electric strength of machine insulation is defined as the r.m.s.
sinusoidal voltage which causes breakdown when applied for one minute.
The present article refers only to 6 and 6.6 kV machines with
continuous mica-tape compound-impregnated insulation. The mean
breakdown voltage of coils has been given as 30 - 42 kV (the lower
value relating to insulation of reduced thickness) and the minimum
voltage to 22 - 23 U. The great difference between the maximx-
and mini-inn values should be noted. Curves of the distribution of
breakdown voltages of coil insulation are given in Fig.l. The
scatter of results, though wide, is normally distributed and depends
on the non-uniformity of the insulating material and its method of
application. As usual in cases of this kind, the breakdown voltage
depends on the size of the electrodes. Curves of the probability of
breakdown of compound-impregnated mica-tape insulation of 6 - 6.6 kV
Card stator windings are given in Fig.2. The dotted curves relate to
1/3 values re-ealculated to a constant electrode area by a formula which

is given. Because of the electrode area effect, the breakdown
voltage for windings as a whole will be lower than that of individual
coils; curves displaying this effect are given in Fig.3. The results
confirm that the test voltages in the standard rOCT-183-55 for the
insulation of 6-6.6 W are correctly chosen and correspond to the
actual insulation level. The disadvantages of using higher test voltages
during manufacture are explained: machines made to the present test
voltage level have proved reliable. The use of voltage tests for
maintenance purposes is then discussed at length. The level of test
voltage that can be considerednon-destructive to the insulation is
considered. Data about the probability of breakdown of new mica-tape,
compound-impregnated insulation which has not been subjected to
preliminary high-voltage testing are given in Fig.4. These curves
are derived from tests on 160 coils made with reduced insulation in
order to get a reasonable number of breakdowns. The results show that
when the breakdown voltage level is high, compared with the value of
the frequently applied test voltage, the latter makes little difference
to the probability of breakdown. However, when the test voltage is
nearer to the breakdown voltage there is a considerable increase in
frequency of breakdown. These results show that frequent application
for one minute of voltages of 13.2 and 21 kV would cause deterioration

the test voltage. In general, application of a voltage much over
1.5 times the rated voltage will cause damage. This argument
is developed at length and it is claimed that still lower
maintenance test voltages, not greater than 1.2 - 1.4 rated
voltage,- should be used if insulation has been in sery-ice for
a long time or is in bad condition. There are 4 figures,
4 literature references (all Russian).

water absorbed on exDosure was determined and -(the results
are given in Fig. 2. It will be seen that the moisture
absorption was much greater when the insulation was finished
with an external covering of cotton tape, which, indeedq
absorbed most of the moisture. The total quantity of moisture
absorbed, the a.-ii-ount absorbed by the surface tape and the
ai-11ount absorbed by the mica insulation are shown in Fig, 3~ It
will be seen that what little moisture is absorbed by the
micafoil is -raostly held in the outside layers. There
is at present no satisfactory method of assessing the

unsatisfactory. In deciding whether a machine can be
connected-up without drying, the important factor is the
characteristics of the insulation of joints and wirding

of this insulation. This cuestion was studied by making
surface-resistance an6 flashover tests on wet micafoil
compounded 6-kV insulation treated with grey enamel. The
tests were made on sections that had been in water for
2 and 25 days. The results are given in Table 3 and the
results are discussed. It is concluded that there is no

is used (Fig 1) which automatically cuts off the pyrometer-

TEXT: The Nizhne-Tagillskiy metallurgicheskiy kombinat (Nizhne-
Tagillsk Metallurgical Combine) has developed an automatic program
control of furnace temperature, based on graphs of the regimes of
heat treatment. The workers of KIP and automation designed special
pneumatic transducers to operate in combination with standard blocs
of a unified aggregate system (AUS). The pneumatic regulates the
pressure at the outlet by a adjustable lever and in relation to the-
setting of the throttling device. The control system contains an
electronic potentiometer, with a programming arrangement, The regu-
lating bloc is a pressure booster. The bloc of remote control and
the switch relay allow a transition from automatic to distance and
manual operation..The temperature of the furnace is indicated by
