ABSTt-.ACT: This Author Certificate presents a transistorized state interrogation
device for an electronic counter which contains a decatron control circuit. To
simplify the device, the cathodes of at least one decatron are connected through
control transistors to the counter digits. The.base of one of'the output transistors
is connected to the emitters of the control transistors and the base of the other
output transistor is connected -through a resistor to the decatron cathodes. To insure
control of an unrestricted number of counter digits with the use of several decatrons,
the zero cathode of the preceding decatron is connected through a resistor to ground
and directly to the control circuit of the following decatron. One of the free
cathodes of the precedir4; decatron,in connected through a capacitor. to the base of the
control transistor whose collector in cormected to the second cathode of the following
decatron. To eliminate digit bypass of the decatron cathodes more than once in the
interval between two counter pulsesq a transistor Js connected in the circuit of the
first cathode of the first decatron, - the circuit of. the first cathode of the following
decatron is disconnected, and a resistor is connected in the circuit of the second
cathode. The emitter of the control transistor id connected to a negative voltap

MT: The authois present the results of the observation of the total
solar eclipse of Februa:rV 15, 1961, on the 3.2-cm wavelength. The'observations
were carried out by an expedition of the Main Astronomical Observatory, AS USSR,
at Rostov..by means Df a mirror radiotelescope (D = 3 m) andusing the scanning
of antenna directivity diagram. Variations in the total-flux of radio emission
were recorded during the course of the eclipse. The results obtained are pre-
sented graphically. Dimensions of radio emitting regions, related *to visible
active regions on the Sun (sunspots at the limb and a flocullus in the disk
center), were determined from the curve of flux variation, as well as their ccn-
tribution to the total radio flux from the Sun. A large .residual flux is noted
at the instant of full phase (4.2% of the total solar flux).

ABSTRACT: It is reported that in March 1965 the sunspot group No. 23 (numbered
according to the bulletin "Solnechnyye dannyye" -"Solar Data") which was under-
going disintegration, suddenly increased six-fold in area between March 18 -and
19. On March 19, 1965 the flux of radio emission from the source associated with
the group and observed simultaneously on two wavelengths, 3. 2 and 4. 5 cm,
through the Great Pulkovo radio telescope (the resolving power of the telesccpe
being vj 21,$ respectively), was also seeif to increase by almost as

much. The dimensions of the source, constan: throughout the entire period of
observation, were V.5 on the 3. 2 - c m wave, and 2,3 on th e 4. 5 - c m wair e.
On March 19. 1965 the brightness temperature. of the source, assuming its
circular outline to be symmetrical was compui ed to be 120, OOOK on the 3. 2-cm
wavelength and 170,0001( on the 4.5-cm wavelk!ngth. The kinetic temperature of
the source, computed ort the basis of these dat x, was 200, OOOK. In comparison
with March 18, on March 19, 1965 the kinetic -,emperature of the source increased
four-fold, and the amount of emission eight-foA., The effective center of the
source's radio emission before and after March 19 was above the photosphere at a
distance of (0. 04 t 0. 01:1 - R,.-) on the 3. 2-cm A avelength and (0. 05 � 0. 01) A(.) on
the 4. 5-cm wavelength. N; close correlation was observed between changes in the'
area of the optical groxqp of sunspots and the fl ix of radiation from a radio source
corresponding to it, which agrees with results obtained earlier by the authors on
the same wavelengths. [Translation of abstra!.Aj ISPI

ABSTRACT: On 18-19 March 1965, the size of the group of sunspots No. 23
[according to the numeration used in the bulletin "Solnechnyye dannyye' ' (Solar
data)], which was in a stagies of decay, suddenly increased sixfold. On 19 March,
the flux density from EL source connected with this group increased by approximately
as many times. The source was observed with the large Pulkovo 'radio telescope in
.j7* -
the 3. 2- and 4. 5-cm wavelengthe (telescope resolving power of ~1. and 1,.3
respectively). Source dimensions, which were constant during the entire period
of, the observation, were at the 3. 2-cm wavelength and 0,3~ -at the 4. 5-cm

wavelength. On 19 March 1965 the brightness temperature of the source calcul.-Aed,
assuming its circular symmetry was 120, OOOK at the 3. 2-cm wavelength and
170, OOOK at 4. 5-cm wavelength. The kinetic temperature, calculated on the basid;
of these data, was 200, 000K. On 19 Marc~, the optical thickness of the radiating
region was 0. 9 at the 3. 2-cm wavelength and 1. 8 at the 4. 5-cm wavelength. The
emission measure was 'I ffidi-0,5'. i0m.. . On 19 March 1965 as compared Nvith
18 March, the kinetic temperature of the source increased fourfold, and the ernis--
sion measure increased eightfold. Before and after 19 March, the effective center
of source radiation was above the photosphere at a'distance of '(0.0ftb-01) RE) at
the 3. 2-cm wavelength, anti ~(kos**V RO at the 4. 5-cm wavelength. No
close connection was observed between the variation in the area of the optical
sunspot group and the flux radiation from the corresponding radio source; this
to in accord with results obtained earlier by the authors for the same wavelengths,.

It was estabUshed that the depp and narrow "anomalous minim" of the
resistance p3Dtted against the -0 of r'otation ( q~l-_00 and 900)
correspond to -xima of the Ban field; a qualititive explanation for
this variation is given: a sharp reduction in the effective mass should
occur in directions perpendicular to the planes of the pplybedron bound-
ing the first Brillouin zone, provided these planes intersect the Ferzi
surface; in the presence of several groups of electrons and,holes, the
positions of the extrems, becme shifted and may depend on H.

followed by slow cooling to 500 C. The resistance
results 'at zero field) are compared with theory and
the results of others; certain discrepancies are
revealed, but the discussion of these does not, horever,
form an important part of the paper, most of Tifiich is
devoted to the magneto-resistance and Hall effect
results given in Figs. 2-4. The various groups of

PP. 1971 - 1980 (USSR)
ABSTRACT: The inlrestigation of two problems is the subject of this
paper: The magnitude of surface strength of isolators in
vacuo and the breakdown between metallic electrodes in
vacuo. As the work reported in this paper was concluded in
1954, no use could be made of the information found in
references 4 and 5. The vacuum plant was equipped with a
hydrogen condensation pump, which operates on the following
principle: The gases are liqi2efied at the surface of liquid
hydrogen and then are drawn off. This pump was described
in reference 6. This is a description of the plant USE.d in
the breakdown experiments. The following experimental evidence
is presented: 1) When the vacuum surface strength of Insulators
is investigated , it appears that the breakdown procee-Js

insulatora do not exhibit a greater strength. Plexiglass and
vinyplast were found to have the higheat strength among
the insulators investigated, 2) As regards the second problem
it was foiind that long before the actual breakdown between
metallic electrodes in vacuum a current between the electrodes
is generated. It is mainly an electron current which causes
the destruction of the anode. 3)The electric strength is
not increased b,, a better de-jassing o~.4he elCetrodes. 4)
Also, varying the pressure 1.n the ranEp 10 to jo- H9-
has no effect either
on the breF~.kdown along insulators or on the breakdown between
metallic electrodes. There are 7 figures, 4 tables, and 10

PERIODICALt Atomnaya energiya, 1959, Vol 7, Nr 2, pp 117 - 121 (USSR)
ABSTRACT: Most di' -awbacks of the.pump described in referelice 1 are elim:i-
nated in the newly developed pump by the fact.,6hat the hydrogen
is liqlaified directly in the pump. Two sectional views show
the components and the construction of the pump as well as give,
to a certain extent, description of.the.components and their
functions. The liquifier is in,connection with the compreascr
(10 m-'/h), but can also be attached to a 17 m3/h compressor be-
cause it has sufficient cooling surface. The operational capacity
of the pump was tested with an iron container of/V 1.5 m3 c()n-.
tent. As the container had a number of flanges and threaded pipe
connections, special inside cleaning was impossible and due to
this fact a: va-caam of mm gg'was achieved. The suction
rate of the pump was experimentally determined to be 37.1o3 1/sec

that this rate -as independent of the pressure. A separate
test established that the pump functions even if there is a
considerable formation of gas in the vessel to be evacuated and
if there is a considerable amount of dirt on the cooling surface,
By inserting a water cooled shutter between the recipient anei
the pumip the auction rate was decreased to 17-103 I/sec and even
under these conditions-gt the evaporation of iron for examples
a vacuum of I - 1-5-10 mm Hg was achieved. There are diagrams
showing the dependency of hydrogen consumption in case of strong
secondary gas formation and the dependency of the liquifier's
capacity on the pressure and the thermal stress respectively.
The maximum capacity of the liquifier is rJ 4 1 of liquid
hydrogen/h at 60 atm. Calculating this data for a jo m3/h-
compressor, it means 2-5 lit/h. The maximum evaporation of the
whole installation is A12i/h. The aggregates of the pump consume
4 13 kw at a pumping efficiency of 37.103 l/sec, including the
electric energy needed for liquifying the nitrogen in the liqui-
fier. When the energy consumed for producing the nitrogen :.rieeded
for cooling the main cock is also considered, the total con-
sumption is ev 17 kw. An oil diffusion pump of the same capacity
Card 2/3 has a higher energy consumption. B. P. Batrakov and V. 1. Sharonov

TITLE: Investigation of Galvanomagnetic Phenomena in Chromium at

PERIODICAL; Zhurnal eksperimentallnoy i teoreticheskoy fiziki, 1959,
Vol 36, Vr 6, pp 1650 - 1655 (USSR)
ABSTRACT. Galvanomagnetio phenomena in transition metals have hitherto
not been investigated to any considerable extent within the
range of strong fields, i.e. in the case of a cosiderable in-
crease of resistance in the magnetic field. The variation of
resistance in molybdenum and tungsten (Refs 1,2) as well as
in platinum, and the Hall effect in platinum (Ref 3) has already
been investigated. In the present paper the authors deal with
investigations of the Hall effect and the variation of resistance
in chromium in magnetio fields of up to 27000 Oe within -the
temperature range of from 4-2 _ 780K, as well as with some
earlie.-r investigations of zirconium. The shmples were obtained
by means of vacuum distillation and were needle-shaped ~diameter
0.35 ffm, length 8 mm). Measurements of the temperature dependence

of the resistance of these samples (without field) are given
by table 1. In the course of investigations of galvanometx-!.o
properties, the direction of current coincided with the lon.-
gitudinal axis of the sample, and the magnetic field was pox-
pendicular to it. The anisotropy of resistance variation in the
magnetic field amounted to 4% as a maximum. The diagram in
figure 1 showe the course of the resistance variation in the
magnetic field; at helium temperatures the resistance shovis a
practically linear increase with growing field strength. Within
,--thO,-AB!Ug,P of 10 to 27 kOe the resistance increasei3 to about
three times its amount. Figure 2 shows the dependence of the
Hall constant R on R at 780 (very slight, practically linear
decrease with increasing H) and at 4.9-0 (exponential decrease
to about 5 kOe, and then linear decrease to 27 kOe). The ji,early
field-ind.ependent value at nitrogen temperature (R- 3-4-io-305U)
differs only little from the value at room temnerature (3.6).
In the following the results obtained are discussed and partly
compared with those obtained for platinum. For the purpose

ABSTRACT: The present paper is concerned with the determination
of the uLtimate vacuum of a hydrogen condensation pump
and the possibility of using liquid helium to improve
this ultinate vacuum. Since it was expected that in
order to achieve the ultimate vacuum it is essential
to exclude the penetration into the vacuum chamber of
the oil diffusion pump vapour, a special apparatus was
built in which all possible steps were taken to minimise
this effeot. A schematic drawing of the apparatus
employed is shown in Figure 1. The apparatus was placed
in a 40-litre vessel 1 . The vessel was evacuated by
the oil diffusion pump 2 The system was isolated
from the oil-diffusion pump by the liquid nitrogen cooled
vapour trap 3 . On the low vacuum side, the oil-
difrusiOrL pump was evacuated by a two-stage mercury-
Cardl/4 diffusion pump incorporating a liquid nitrogen trap.

The polished copper screen 5 , which was in the form
of a cylinder and surrounded the working region, was
also ndtrogen-cooled with the aid of the dewar 6 .
In addition, there was a liquid nitrogen cooled venetian-
blind type trap 7 - Inside the s,croen 5 there was a
polished cylindrical screen 8 , made of copper with a
liquid-hydrogen filled sphere 9 attached to it. The
screen 8 and the sphere 9 form a fast condensation
pump. Tho space inside the screen 8 was thus
surrounded by walls cooled down to liquid-hydrogen
temperatures and the rate of pumping for nitrogen within
this space was 30 000 litres/sec. The sphere 10 inside
the screen had a diameter of 155 m and could be filled
with liquid hydrogen or liquid helium. The calculated
pumping speed for nitrogen by the sphere 10 was
8 000 litres/see. The space inside the screen 8 was
thus isolated from the remaining part of the apparatVLS
except for apertiLres whose total areas was about

apertures was less than 100 litres/sec and hence the
region inside the screen 8 could be looked upon as
corresponding-to the ultimate vacuum of the condensation
pumps, provided the pressure outside this region was
about 10-8 mm Hg. Two manometers were employed, namely
12 anel 13. . In order to reduce the evaporation of
helium between the manometer 13 and the sphere 10
provision vras made for a narrow copper screen 14 . The
low pr4msures were measured with standard ionization
manometers, type LM2. These manometers can measure
pressures down to 5 x 10- 9 mm Hg. An Alpert gauge (Ref

that a VaCUUM Of 10-10 mm Hg could be obtained in all

pp 828 - 831 (USSR)
ABSTRACT: In an earlier paper (Ref 1) the authors described the
results of investigations of the temperature dependence
of the susceptibility of barium ferrite in weak fields
below the Curie point. A feature of the dependence
I = f(T) for barium ferrite is the absence of' an increase
in the initial susceptibility on approaching the Cxu-ie
point (Hopkinson effect). Therefore, the authors consider
it -of interest to elucidate whether this feature is
restricted to barium ferrite or 'whether it is also a
property of other rigid ferrites. Furthermore, the
investigations on barium ferrite were continued in weaker
fields than was done in the earlier work (Ref 1).
The magnet-isation of the specimen wan measured
by mean-a of a ballistic method in the same way as in the
Cardl/3 earlier work. The temperature dependence of the magneti-
sation was studied in ferrites of barium, strontium and

lead. Ex,-~ept for some changes in the temperature regime
for the lead and strontium ferrites, the specimens wexe
produced by the same methods which were used earlier,, The
measu.red results show that -the investigated ferrites do
not possess any Hopkinson effect. In addition to the
ordinary Hopkinson effect, maximum susceptibility wa~,
observed for cobalt in the range in which there is a
change in the sign of the anisotropy constant. It Is
pointed out that this character of the changes in IJK
values for barium ferrite is caused not so much by the
th
changes in ?K = f(T) curve but by the fact that the
satuiration magnetisation decreases to a considerable
extent even at temperatures differing greatly from that
of the Curie point. In the case of soft (cubic) ferrites,
which show a Hopkinson effect, a rapid drop in the
saturation magnetisation begins at relatively higher
temperatures than it does for barium ferrites.

of the saturating vapoTs was here applied. This method consisted in the
followings The gas under investigation is condensed in a high vacuum on a

that the hydrogen.final vacuum may be increased in a helium condensation

TITLEs Automated Hydrogen Liquefaction Cycle Without Ga.s-Holder
PERIODICALs Khiinichei3koye Masilinestroyeniye, 1961, No. 1, pp. 1-2
TEXT& The incr,sased use of liquid hydrogen and other liquid gaseis
for cooling large machinery (Refs 1-4) is discussed. In order to simpli.-
fy the complicated maintenance of gas-holders, a closed cycle liquefac-
tion device without gas-holder and with automatic pressure adjustment of'
the circulating gas was developed (Fig 1). The cycle was used to supply
the hydrogen liquefi3r of a condensation pump at a rate of 4*lo4 1/890
(Ref 2). The limit amount of liquid hydrogen is determined by the posi-.
tion of the hydrogen oatlet tube in,the liquefier collector. Liquid
hydrogen collects up to a certain level, above which it is carried away
by the outgoing gaa. Finally, the entire amount of gas can be pumped in-
to cylinders through a filter (7) and a valve (8). Both automatic valves
(6) and (11) are pneumatic; their performance is based on the deflectioiL.

of valve (11) is insured by gas contained in the ballast container (9)
and of the valve (6) by atmospheric pressure. Fig 2 shows the design
of the ultimate p.-Cessirre valve; its body consists of two parts (1) and
(5) divided by a :20 mm diameter rubber membrane (2). The valve ensures
the upper prossure limit to an accuracy of 1 atm at a 200-atm maximum
pressure. Rubber membranes of 1 mm thickness withstand pressure drops of
300 atm. Fig 3 shows the design of the automatic gas supply valve con-
sisting of a short a linder (1), the ends of which are covered by two
rubber diaphragms (2~- The operating diameter of the diaphragms is 105 mm
and the valve maintains a constant pressure to an accuracy of 0,002 atm,
High accuracy is essential in order to prevent air intake through the
pumping line of the compressor. A two-stage R9,a(KVD) air compressor of
lo m3/h capacity per operating pressure of 60 atm was used. High compres-
siorL in the cylinder leads to intensified decomposition of lubricants,
which necessitates careful purification of high-pressure hydrogem before
entering the liquefier. Purification with the help of an adsorption fil-
ter and a freezer ensures continuous operation of the liquefier for six

months. Analysis of the. operating gas after six months showed that the
content of oxygen does not exceed 0,05qo, which freezes quickly. The
freezer is a counter-flow heat exchanger with its lower part immersed in
liquid nitrogen. The consumption of nitrogen for one compressor is 0-5
0.8 liter per minute. One compressor is sufficient in continuous opera-
tion, whereas two must lie switched on prior to attaining the normal. opera-
tion rate. During opere.tion with two KVD compressors liquid hydrogen be-
gins collecting after tvio hours. In steady conditions the throttle valve
re4uired no regulation. The liquefaction cycle of the installation con-.
sists of: two KVD compressors, two 40-liter containers, one of them fill.-
ed with hydrogen; a BIA-2 (VN-2) forepump for pumping out nitrogen; and
purification devices as described above. The installation requires a
working area of 1.5 2 m2. There are 3 figures and 4 references:.2

convection, the critical thermal stresses and the corresponding maximum
field strengths are essentially lower. Thus, in coil CII a delay time
of 1 sec corresponds to a field strength of 31,000 oersteds, and
Ir 10 sec corresponds to 26,000 oersteds. In the hydrogen flow the
thermal loads are independent of distribution which is not the case for
natural convection. The main results of the experiments are shown in
Table 2; they correspond to a pressure gradient of from 0.4 to 0.5
atmospheres. The thermal stresses in natural convection are about twice
as low as in hydrogen Tlows under pressure. In all coils the critical
thermal loads.wexe coneiderably lower than in the preliminary experiments
withone single slit. Besides, the values of q are gradually reduced
when instead of coil CJ, coils CII and CIII are used. The Reynolds
numbers for CI, CII9 CIIT are 3500, 1000, and 500, respectively~ These
diverging experimental results are probably not due to the different
construction of the coils but to the different conditions of circulation
of hydrogen. With high-purity commercial aluminum, field strengths of up
to 100,000 oersteds can be attained with coils of - 1 M. 'The liquid
hydrogen necessary for such a solenoid cannot be provided for even by
the most up-to-date methods of liquefaction.
