TEXT: A study has been made of new types of chromium aluminum magnesium
silicate catalysts (Cat) in the rolvmori7.qtinr of ethylene to polyethylene,
and of the activity of Cat as degdnaent upon tne method of their introduc-
tion into the chromium oxide.. The activity of Cat has been shown essen-
tially to depend on the method of synthesis, the chemical composition of
the carriers having no appreciable effect upon such activity. The optimum
ratio of Cr 6-t and Cr 5+ oxides in the chromium metasilicate catalysts
concerned has been found to be 40-55 :45-60; the maximum polymer yield per

g of Cat has been 92 and 114 g, respectively. No relationship has been
observed between the catalytic activity of Cat and their thermograms, their
porosity, snecific pore volume, and apparent density. All the polymers
obtained have been found to have a highly crystalline strlcture. Th'.
authors assumed the active part of chromium natalysts to cons,-st saltq
of chromous arid or acid salts of chromic acid. [Abstracter's note:

TITLE: Individual Tone Am lifier (ITU) (Individuallnyy tonall-
nyy usilitelf (ITU~)
PERIODICAL: Vestnik svyazi, 1959, Nr 2, pp 10-ler, (USSR)
ABSTRACT: The article discusses the technical specifications of
the amplifier as a whole, and describes its seFarate
component parts. The ITU amplifier is designed to
complement the SUTU type amplifier, already in use, and
the two types are basically similar in respect to oper-
ating frequency range, amplifying capabilities, and
possibilities for equalizing arrangements in operation,
in corresponding types of circuits, although the ITU
contains but one equalizer, which is changeable, The
ITU is intended for use in a variety of operating con-
ditions, and is therefore to be produced in several
models: for 4-conductor cable circuits the ITU-1 (way
Card 1/4 stations) and !TU-4 (terminal stations); for connection

into steel and copper air circuits, the ITU-'; for use
in bi-metallic circuits and with PRVPM cable with con-
ductors 1.2 mm in diameter, the ITU-3; for organiza-
tion of auxiliary communications-along cable ci-rcuits,
the ITU-5 and ITU-6. The ITU contains equipment for
induction, and tone calling. On 4-conductor circuits
the tone call equipment can be used for sending dis-
tance-dialing pulses. The author describes the system
provided for correction of amplitude-frequency distor-
tion., accomplished by four different equalizing cir-
cuits in the amplifier. The amplifier element is a
three-stage transistor unit, using PlV triodes in the
first two stages, with grounded emitters, which cir-
cuit gives the greatest power amplification, The
final stage uses a P'rl with grounded base, to decrease
non-linear distortion and stabilize output resistance,,
The author notes that the triode types Pi, Ve-, and P3
are soon to be replated with a sealed triode unit.
Maximum output power of the amplifier is 70 mw, with
Card 2/4 less than 3% distortion at 420 cps. The YTU consumes

Individual Tone Amplifier
240 mw of power, 15-16 times less than the tube-oper-
ated SUTU. Amplifier stabilization is discussed. The
receiving unit for tone dialing and calling uses a 3-
stage amplifier, a resonant system, and rectifying
bridges. First and second stages of the-amplifier use
Pl triodes, and the third a M, guaranteeing suffic-
ient powei-for relay operation. All 17, stages have
grounded emitters. Switching to any of the three
calling frequencies of 2100, 1900 or 1600 cps is prov-
ided, Relay operation band-width on any one frequency
is 200 cps., The tone dial and calling circuit is des-
igned around the Pl triode, and also provides for fre-
quency switching. The transmission and reception of
calling signals is diagrammed, There are C'_- circuit
diagrams and I block-diagram.

means of a method by D. Ivanenko and A. Sokolov
(Klassicheskaya teoriya polya, Aoskau-Leningrad, 1951,
p. 273). The character of this method consists in the
fact that the solution of the generalized Legendre dif-
ferential equation is set up in form of a product of two
arbitrary functions. In the equation thus obtained the
author neglects quantity which at increasing 1 rapidly
tends towards zero. This makes an accurate determination

ABSTRACT: In mathematical physics, special functions which are exact solutions
of differential equations are often approximated by simpler func-
tions. The authors mention*the method by Liouville-Steklov (Ref 11
for differential equations of second order, and then explain the
method of approximation suggested by Wentsel, Kramers and Brillouin
(Ref 3) (WKB method) for the solution of the wave equation. In this
method, already the first approximation gives good results. In the
present paper, this method Is put forward in a generalized form.
Besideaq better approximated solutions are derived for a number of
cases by finding the solution of a differential equation "neigh-
boring" the original differential equation. In the first principal
part of the present paper, the solutions (2,11) and (2,12) are
obtained by the WKB method starting from the linear differential
Card 1/3 equation of second order u" + f(x)u w 0 (2,2). The first solution

B014/B005
holds for f(x)>O, the second one for f(z)4.0. The authors point
out that many problems of quantum mechanics can be solved by the
method put forward here. This method gives no result near the point
X a X0 where f(z 0) - 0. Here, the required function is not approxi-
mated by harmonic functions as in the first case nor by exponential
functions as in the second case, but by Bessel functions. In the
second principal part, asjuptotic formulas for regular hypergeometric
functions are derived. The spherical functions are dealt with first.
The authors proceed from the Legendre functions (30) and (3.2), and
write down the four solutions (3,3) and (3,4). From the latter, the
known asymptotic formulas for the Legendre functions (3,20) and
(3,21) are derived by the above-mentioned method. The application
of these functions is shown by a treatment of the elastic scattering
of particles in a Yukawa potential. Further, the approximate
formulas for the Jacobi functions of first and second type, and for
the Gegenbauer functions are derived. There are 1 figure and 16
references, 10 of which are Soviet.

ABSTRACT: In the present paper the authors calculate the phase shifts
of the elastic scattering of Dirac (Dirak) particles in
second approximation with respect to the interaction poten-
tial. An expression is given for the general solution of the
free Dirac equation of this problem. This solution is not
limited by a condition of finiteness in the origin of coordi-
nates. This solution of the free equation is also an asympto-
tic expression for the Dirac equation if there exists a
spherically symmetric short-range force center. The next
part of the paper gives an approximate solution of the Dir'ic
equation for the case of a central field. An integrJ equation
Card 113 equivalent to the Dirac equation is given for the case in

which there is no vector potential and the scalar potential
is spherically symmetric. The interaction energy is considered
as a perttfmtion and the calculations are carried out in
second approximation; the wave function corresponding to
this approximation is given explicitly. The calculations
are discussed step by step and the expressions found for
the phase shifts are given explicitly. Neglecting the terms
which are square with respect to V(r), one obtairs the
same results as in the theory of damping for the scatterinE
of Dirac particles. For snall values of the scattering phases,
the results of the first Bor*pproximation are obtained. The
results of this paper may be used also for the inveQti~.~atior
of the scattering by a Coulomb (Kulon) center,(V(r)=-ze2/r).
The integral values of the phase shifts diverge in this case,
but correct results are nevertheless found. Finally, ex-
pressions are given for the scattering amplitudes (in second
approximation) and for the differential cross section. There
are 4 references, 2 of which are Soviet,

TEXT: Proceeding from the values of the phases in first approximation, the
factor DUS) is calculated for a certain spherically symmetric potential in this
paper. According to Uott and Massey (Ref 1), the exact formula for the angular
distribution of a partly polarized beam of Dirac particles contains a factor of
the form W) - i[,-(~)g%~,) By means of the theory of damping by
A. A. Sokolov it was possible to generalize the results obtained by Mott to
scattering by a center of force (which has not only an electric charge but also
a magnetic moment), and to investigate also the case of a random potential. In
first Born approximation, fM and g(-.4) are known to be real, and D(%%) - 0
holds, which means that scattering has no azimuthal asymmetry. In order to deter-
mine the complex scattering amplitudes, it is necessary to take also the
quadratic terms into account in the exact formulas when developing the exponents:

The value of the phases need, however, not be taken into account in second
approximation, and consideration of the first approximation will be sufficient.

explicitly written down. In the case of an arbitrary spherically symmetric
scatterer, D(%%) - 2[f Re (4)91M(~) - fI,(,~)gRe(,")] holds. In order to determine
D(4') in the second highest approximation, it is necessary to know the phases in
second approximationo The difficulties arising in summation are, however, not
yet overcome. The results obtained by the present paper may also be applied to
the Coulomb field, but first a screened Coulomb field must be investigated

In the expression for the Yukawa amplitudes, the passage to the limit may then
be made to the pure Coulomb field; 7(r) Ze2 , V(t) - -Ze 26(t) . By the

In conclusion, several sums are calculated. The author thanks A. A. Sokolov for
his interest in the present paper. There are 6 references, 5 of which are Soviet.
