TEXT: The authors study small deviations of a stellar system from the
steady state. For this purpose, the authors assume some law of distribution of
additional density (without explaining its selection); this law contains unluioi.-n
parameters which are selected in such a way that Boltzman's equation should be
satisfied as precise as possible. (The paper contains errors: some tercis are
omitted In the linearization of Boltzmanis equations; parameters k, m and 1 are
assumed now constant, now dependent on coordinates; the real part in formula 7
is separated in a wrong way; addition of forces of gravitation and light pressirp,
introduced by T. A. Agekyan for certain conditions, P. -0.7, cannot be applied to
"he entire Galaxy. Reviewer). There are 6 references.

i TOPIC TAGS: line broadening, forbidden transition, electron spin resonance,

ABSTRACT: The authors investigate quantitatively the change in forbidden-resonance
line shape brouE;ht about by exchange interaction between electron spins. The calcu-
lations involve a determination of the absorption energy from the imaginary part of
the complex susceptibility, and account is taken of the fact that the Hamiltonian I
assumes different values for isotropic and tensor interactions between the electrons
an! the nuclear spins. The second and fourth moments, are calculated. 7he calcu-
lations show that when the interaction is isotropic, there is ne dynamic polarization
of the nuclei, but the Overhauser effect can result when the exchange interaction is
saturated. When the interaction has a tensor character, as is the case at low temper-~
aturcs, there ir, dynamic polarization, but no Overhauser effect. This agrees vith
recenti, experimental data. Orig. art. has: 9 formulas,

TITLE: Determining the irregularities in the efficiency of ferromagnetic
carriers for phototelegram reproduction.
PERIODICAL: Elektrosvyazl, no. 5, 1961, 58
TEXT: The serial production of magnetically rerecorded phototelegram repro-
ducers using the standard 6.25 mm tape Is being prepared this year in the USSR. As
amplitude modulation is used, the elimination of irregularities in the efficiency
of the tapes becomes an important problem. Distortions are caused above all by
parasitic amplitude modulation connected with the presence of defects in the ferro-
magnetic coating of the tapes. In the present article, the authors examine these
defects and describe a device allowing to count the exact number of defects in the
tape. For the examination of the defects, the authors divide the defects into
two groups according to the nature of the distortion they cause in the recorded
signal. To the first group belong the defects connected with the non-uniformity
of the magnetic characteristics of elementary sections of the magnetic carriers.
To the second group belong the defects the consequence of which Is an interrupted

contact between the tape and the recording head. The appearance of a gap betweeL
the tape and the head brings about a considerable fluctuation of the sigrall level,
especially when short wavelengths are recorded. Therefore, when defects of Uv"'
second group are present, the depth of the dip in the reproduced signal depends
on the recorded wavelength. The geometricdl dimensions of the defects of the
first group in the direction of scanning ( Allongit.) are given by the relation;
A llongi. = vt (1)
v being the velocity of the tape and t the duration of the decrease of the repro-
duced signal level. If the depth of the dip in the reproduced signal is determined
by the geometrical dimension in the direction perpendicular to scanning, this
dimension is given by: A c c (1 10'. -b/20) (2)
where C Is the width of the path of the record, and b is the depth of the dip in rc-
production. The determination of the geometrical dimensions of the defects of ti,r;
second group is much more difficult. The real geometrical dimension of the defe.-t
1) is, however, much smaller than the section of the band ( 41equiv.) aiong

which the contact between the tape and the recording head is interrupted. Since
the duration of the dip in the reproduction is determined by 4,leauiv., it is
appropriate to evaluate defects, not by 4 1, but by a 1 (which Is much easier)
and to resort to the following relations, analogous to'~Yj'and (2):
Alequiv. ~ vt b/20
'dCequ = C (l - 10- (3)
Ass*jm-ing that the tape is sufficiently efvaitic and that its contact with the re-
cording head is perfect in the absence of defects, it is possible to show that,
for toroidal heads, the length of the tape section corresponding to the broken
conta;3t is: 41 2 h are co R
equiv. - R + h (4)
where R is the radius of curvature of the head, and h is the height of the defect.
In spite of the steps taken with a view to improving the quality of magnetic tape4
the tapes produced in the USSR at present still possess numerous defects. An ex-
perimental check of the quality of the tapes is therefore necessary. The magnetic
recordi-r.g laboratory of the Moskovskiy elektrotekhnichesk.'y institut svyazi (M("~_
now Electrotechnical Institute of Communications) has devoloped a special elec-
Uromic device allowing to count the exact number of defects in the tape &nd

In the presence of defects producing distortion of more than a hundred picture-
elements, an indicator operates in conjunction with a counter of slow dips. The
counting device, as a whole, operates as follows: The signal from the reproduc-
tion amplifier is applied to the input of the device, If the reduced signal-level
is below the limiting threshold determined by the formation block, this block will
form a pulse the duration of which will be equal to the duration of the dip. The
leading edge of this pulse triggers the kipp-relays which determine the duration
of the reproduction dips that get into the corresponding channel. The pulses from
Card 5/7

2057 s1 106/61/000/005/00 51~YA
Determining the irregulabities A055/A133
the kipp-telays are delayed (by a delay-unit) for 20 microseconds, i.e. for the
time necessary for the operation of the"mismatch circuits". These pulses, together
with the pulse formed by the formation block, reach then the mismatch circuits
of the corresponding channels. In the channels where the duration of the kipp-re-
lay pulse is greater than the duration of the dip, pulses the duration of which is
equal to the delay time will appear it the output of the mismatch circuit, The
duration of the dip determines thus the presence or the absence of the signal
at the output of the mismatch circuit of individual channels. These signals are
applied to a decoder which decodesthe received combination and triggers the termfn-
al kipp-relay of the channel in the working range of which is situated the duration
of the dip. The load of this kipp-relay is a CG-1 M/100 ("SE~-1M/100") type counter.
Two operating conditions of the counting device are possible: the "counting" con-
dition and the "stop" condition. With the "counting" -condition, selection and
counting of the defects in the tape take place. With the "stop" condition, the
tape-driving mechanism is stopped at the moment of the appearance of the defect,
and the existence of this defect is thus revealed. Experiments have shown that the
most frequent defects are those with small equivalent dimensions (Small6lequil,).
It was also found that the majority of defects cause a decrease not exceeding 3 db

83. Investiption of the Effect of Atropine and ThiosTanalas on the Nervow
System
"Effect of Atropine and Thiospasmine on the Figher Nervous
Functions of Rats," by M. Vanechek and Z. Vatova with tbe Tech-
nical Cooperation of Z. Kvetoneva, Pharmaceutical and biochemical
Research Institute, Prague, Physiologia Bohemoslovenica, Vol 5,
No 4, 1956, pp 46o-467
Report the results of experiments which were conducted to determine
the dosages of atropine and thlospasmine which affect the central nervous
system, and the manner in which these drugs act. Thiospasmine is the
sulfonium analogue of Trasentine H, and was developed by Protiva and
others in 1953. Tests conducted by Votava and Shramkova in 1954 indicated
that thiospasmine has an inhibiting effect on intestinal motility. Chem-
ically thiospasmine is the iodide of 2-phenylcyclohexylacetoxyethyl
d1methyloulfoolum.

The experiments were conducted on white rats. The method of food and
defense conditioned reflexes was used in the experiments. The results
of the experiments were as follows: atropine administered subcutaneously
in doses of 5 milligrams per kilogram of body weight and in doses of 50
milligrams per kilogram of body weight administered orally intensified
the inhibition process in animals with food conditioned reflexes; in
dozes of 25 milligrams per kilogram body weight administered subcutaneously
and 300 milligrams per kilogram body weight administered by mouth it in-
tensified the inhibition process in animals with defense conditioned re-
flexes; atropine in small doses did not produce any excitation symptoms;
th'iospasmine acted on the central nervous system only when administered
In doses ton times those-of atropine; like atropine it produced side re-
sults. (U)

Abstract: A health study of the molding of bakelite articles has
shown that the causes for the appearance of dermatosis
in the workers are nonobservance of safety regulations
(working without gloves, or without shirts) and bad
ventilation (increased formaldehyde content in the at-
mosphere in the work areas), The examination of skin
specimens has shown that urotopine ZT-11: hexamethyl-

effect on the skin, followed by formaldehyde and phenol.

face quality of ingots cast in r-netal molds. Microparosity was not identified, the
structure was fine-grained and ne-ither skm.,; nor inclusinns were observed.
The solubility of Mischmetal in Mg was only 0. 5 to l'i,) , as the Al and Z-n contents
was increased, the solubility of Mischmetal was enhanced. The temperature of
the beginning of crystallization was not affected by Mischmetal additions. At
200C the mutual solubility of Al and Zn fell off whenever either Al or Zn was pre-
ponderant. Specimens with a high Zn content tended to display EL higher maximum
aolubility of the Al and Zn components while Mischmetal had no effect on the
maximum solubility of Al-rich alloys. It follows that the additions of Mischmetal
increase the difference in the concentration of a solid solution at high and low

ABSTRACT: The reaction of RbCl with calcium-silicon containing 67% GaSi? can be
expressed in tho form of a final reaction: 2iVoCl + CaS12 = CaC12 4 21.1a (I'). 2b was
-:'bcrated in --e-mm In the form of vapors. The process of this reaction was st-udied
by (1) continuous regiskrc.-.:z- of the decrease in the charge weight at constant tempo.-
ature, and (2) electrochemically by determining tho polarization of the ca'.'ci= siliccn
electrode in RbCl (polarization current curves vs the value of polarization). The 2 g
briquets (15 mm in diameter and 4.5 mm in thickness), which were made by compression
at 1000-7500 kg/=2 of the mixtures of calcium silicon and RbCl, were used in the
first method, and in the second method liquid calcium silicon was charged into a por-
celain tube containing RbCl. The kinetic curves were plotted (degree of reduction v
time) to characterize the reduction of RbCl (1) at 7000 in vacuum (2-3 x 10-2 =m iig3

various residual pressures of Ar (1, 5, and 10 mm ffg,). The changes of t1r, CaS~ Rbol
ratio within a wide range had little effect on the reduction of RbCl. 7nereffo 0 all
subsequent experiments were made at GaSi2 : RoCl = 3. The changes in pressure duar.1.11-17
briquotting also did not change the reaction parametars. Tho separate plac=-ent of a.
layer of RbCl under a layer of calcium silicon resulted In a noticeablo decroaso in
the rate of reduction. It was thus concluded that the reduction of i~bCl occu--red Most-
ly by the reaction of calcium silicon with liquid RbCl. The optimal sonaitions were
achieved during the two-stage reduction: (1) reduction at 7500V in Ar at=o-phere unde.-
an Ar pressure of 5 mm Hg, and (2) creation of a vacuun in the system and ifuz*ther :-e-
duction at 900C. About 70% Rb was reduced during the two-stage process. 7he abC1 which~
evaporated during reduction concentrated separately from the metal and was recirc,_1-
ated. The two-stage reduction occurred practically without permanent losses of :~601.
The second set of expariments (electrochemical) suggested that the reaction on the
1 2+
boundary of calcium silicon and RbGl occurred in two stages: CaSi.2----rGa * 2Si + 2a and
2rlb,~ + 2e4M. The reaction (1) can therefore be considered as the result of the works.

reduction o Rb occurred in this cell. The calculation of apparent enerV of activation'
made from polarization curves yielded a value (E = 19,200 cal/molo) nearly similar -to
that of the apparent energy of activation obtained from the kinetic data of the Afirsto
set of experiments. Orig. art* has: 3 fig. and 2 tables.

that jiradiation increases the metabolic rate which is measured by increased oxygen consumption The author
concludes that the neurogenic mechanism plays a major tole in this increase whereas the ditect effect of
radiation on CNS is less important.

TITLE: The gas exchange in rats following intrapcritoneal administration of cystine and cystamine
PERIODICAL: Meditsinskaya radiologiya, v. 7, no. 7, 1962, 57-62
TEXT: The mechanism of the radiation-protective effect of cystcine and eystamine has never been clear.
Experiments were carried out on 110 female rats weighing about 200 g. The gas cxchan3e was recorded
automatically and continuously for 60 min. Cysteine hydrochloride (50-1000 mg/kg b.w.) and cystamine
(50-200 mglkg b.w.) in physiological solution were used as protective agents. The pH was adjusted to 7.0
with 10 % NaCl. Cysteine, at a dose of 200 mg/kg, turned out to be toxic (30 */' . deaths within 24 hours). Both
substances affected the gas-exchange only during the first 10 minutes after adminiitration, thus indicating
their effect upon cellular metabolic processes. Cysteine and cystamine did not alter significantly tile oxygen
uptake in rats nor the C02 output 10 min after their administration. The RQ of the rats increased after a
50 mg/kg of cysteine and decrea5cd after a dose of 100-1000 mg/kg. Cystamine brought about a 20%
increase in the oxygen uptake after doses or so, 100, and 150 mg/kg. A dose of 200 mg/kg did not affect the 02
uptake. The C02 Output was somewhat increased depending oil file dose. The protective cffc,.t of these subs-
tances cannot be explained by the decreased oxygen tension in tissues, but primarily by their clRet oil the
general metabolic processes. There are 3 figures.

ABSTRACT: Since 1956, work has been carried out at the ITEIS (Moscovi
Electrotechnical Communications Institute) on the appli-
cation of ferrography to the recording of photo-telegrams.
The article contains a short description of the basic
elementsof the process involved and of some of the items
of equipment. The processes of optical -and magnetic
recording
, are compared in Figures 1 and 2, respectively.
It will be seen that the magnetic method is the simpler
since the "negative" stage is eliminated. rigure 3 shows
the principle of the recording method. The medium used
is in the form of a drum rather than a tape since it is
not inclined to warp or stretch. Tile gap width in the
recording head is between 10 and 15 11, which guarantees
the recording of the entire spectrum of the photo-
telegrqhic signal (1 300 + 550 cls when n = 60 rpm).
The drum diameter is 9 cm7 The other dimension of the gap
is such as to give 5 lines/mm, in the image. Figure 4

perature to prevent condensation of methanol on the windows which
can cause a high background. The operation of the chamber is con-
trolled by automatically varying the liquid nitrogen flow rate,
the methanol temperature, and the temperature of the upper flange
of the lower cylinder. The chamber was tested with an air and me-
thanol filling at 1 and 3.5 at. It could be opera-,,ed at a bottom
temperature of -45 to -700C and a methanol temperature of 10 to
300C, however, the most satisfactory temperatures were found to
be -50 and 200C respectively, giving a temperature gradient in
the working space of 7 deg/cm. At an alcohol temperature above Moc
tbe droplet background was high; when the temperature fell to 0
to 100C the vapor flow was insufficient for satisfactory operation
of the chamber. The authors have given in this paper a good des-
cription and diagrams of the supporting equipment for pumping the
liquid nitrogen and feeding methanol to the dlffU3ion chamber.
The authors state that they are preparing at tne moment a larger
chamber with a diameter of 30 cm and a working pressure of 30 at~

conductor is inserted inside it. Superheating of liquid hydrogen
in the chamber is achieved by reducing pressure with sylphon me-
chanism 14, 15. The pressure on the upper sylphon is applied
through the electromagnetic valve 16 and the magnitude of movement
is controlled by means of the regulator 17. A detailed description
of the electromagnetic valve is given. Gaseous hydrogen purified
silica gel and activated charcoal is fed to the chamber through
the precooler 18 and the needle valve 19, and the pressure in the
chamber is measured by the gauge 20. The authors have given a
brief description of bringing the chamber into operation. The cham-
ber was operated over a temperature range of 27 to 300K (corres-
ponding to a vapour pressure of 4.5 to 8 at.) and a working cycle
of 2 seconds. It was found that by constant superheating, the sen-
sitivity of the chamber increased with temperature. The sensitivi-
ty also varied with the amplitude of superheating, and it was pos-
sible to make the chamber insensitive to relativistic particles.
The consumption of liquid hydrogen was 15 1. for cooling and half
a liter for each hour of operation. 60 1. of liquid nitrogen was

lighting the chamber a pulse lamp 27 was used. To give a good illu-
mination of the chamber light passed through a venetian blind 26,
made of 2 mm organic glass, 10,mm wide, glued together to make an
angle of 300 with the window. Abstractor's note: The angle should

TEXT: The authors review the advantages and simple theory of bubbi'l!
chambers and they describe a propane bubble chamber which has a
capacity of 34.0 x 20.4 x 16.0 cm3, and is intended for use in a
magnetic field of 12000 gauss. The chamber has two windows, 37 x
34 x 7 cm-) made of hardened optical glass. Pressure is applied to
the working liquid hydraulically with the help of compressed air.
The pressurizing unit 1 consists of to electromagnetic valves 2, 3,
and the pressure-drop to a preset level is controlled by means of
the regulator 5. The working temperature of the chamber is 640C,
corresponding to a vapor pressure of 24 at. This temperature is

maintained constant by thermostating the chamber, the hydraulic
duct 6# the pressure controller lp and the compressed air reservoir
4. Unlike other bubble chambers this one has a vacuum duct 8,
passing thilough the working liquid, for admixing with the liquid
solid# liquid# or gaseous substances for investigation. Two types
of lighting were tried. One was lighting through a venetian blind
blockt while the other consisted of passing the light through a
polarizer and photographing it through an analyses. The chamber
was assigned for a study of the interaction of electronst y-raysp
and mesons with hydrogen, carbon and other nuclei. Under certain
circumstances the chamber with the vacuum duct can be used for
scattering electrons with electrons. There are 1 Zigure and 8 re-

ABSTRACT: The neutron detector described in references 1 and 2, with its
paraffin and boron carbide shielding is modified (Detailed

enlarged to 30 mm- It is filled with BP 3 (70 % B 0) of a 140 mm
Hg pressure, the operational voltage is 1700 v and the plateau
approximately 300 v. The enlargement of the diameter of the
counter relatively increased the sensitivity of the counter

sensitivity was made in "good geometry". T1,e following neutron
sources were used; Sb-Be, Ra-13e, Na-D~ Na-Be, T(d,n)He4

ivity, wettability, and critical current density) and determina-
tion of Al losses therein result in the conclusion that in terms
of its effect on the physicochernical properties of cryolite

ABSTRACT: This is a continuation of earlier work by one of the authors (Jung,;irth,
with A. B. Mikhaylavskiy, ZhETF v. 50, 1036, 1966), vhcre the feasibility of quasi-
linear wave transformation in a pWma was demonstrated. Inasmuch as the earlier
paper left open the question whether this effect can play an important role in the
presence of nonlinear wave interaction, the authors analyze the kinetic equation foF
such a case and determine the conditions under which a quasilinear transformation can
or cannot occur in the presence of nonlinear interaction. A table is presented list-
ing the quantities characterizing the nonlinear i~iteraction., the time variation of
the energy density, and other processes accompanying the wave interaction and trans-
formation* A detailed corroboration of the present data io to be published in Czech.
