ABSTRACT: A study has been made of structure formation of carbon-blackpdispersions
in xylene- and- in raw- rubber -soluti(ma _- systems which simulate f illel rabbers.
The exorim~nts were conducted with unmodified and modified common carbon blacks.
The structure formation processes were determined from measurements cf electrical
conductivity and ultimate shearing stress. It was shown that carbon-black disper-
sions~form quasi-equilibrium coagulation systems with thixotropic properties. The
addition of small amounts of rubber to carbon-black dispersions sharply increased
the strength of the structures. The strengthenirg of the nystems was attrfbuted
not only to adsorption of the polymers onto the black, but also to the formation
of macromolecular structures which are oriented along the carbon-black chains to

form a supramolecular network. Chemical or physical modification of the carbon-
black surface changed the surface energy and sharply affected the struCture of tae
dispersions and their mechanical properties. Orig. art. has: 5 figures and 1

laxing elements with short relaxation times of the extended systems indicates the pre-
sence of carbon black - polymer bonds, comparable in strength to intermolecular bonds,
since the carbon black surface has an assortment of adsorption centers with various
energies (more or less weakor than the energy of intermolecular interaction). The re-
inforced structure of the polymer is created in the presence of strong adsorption cen-
ters. The data obtained confirm the concepts advanced in the literatures according to
MAch the reinforced filler - polymer coagulation structures are mosaic in character.
Indeed, the most active from the standpoint of reinforcing effect is carbon black
characterized by the presence of a small number of highly active adsorption centers on
a background of relatively low activity. It is concluded that in an extended rubber
the polymer is present in the form of two structures, one unchanged and the other re-
inforced,, and that there is no distinct boundary between them. Orig. art. hasi 2

ABSTRACT.* The-oxidative annealing of manganese-vanadium spinel was
investigated from 0 to 1000C, using thermographic analysis simul-
taneously with x-ray, cEXstallooptic and chemical methods./ The
first stage of the oxidation is the chemis-o-r-pE-lon of' oxygen on the
surface of the spinel grains and the formation of a solid solution.

ABSTRACT: Bose was born on November 30,1858, at Rarukhal (Dakka)(accord-
ing to other sources he was born at the town of Maymensingh)
in East Bengal. He studied at the English College of Saint
Xavier in Calcutta, and, after having taken the degree of
Bachelor of Arts at the age of 20, he continued his studies
in England at the universities of London and Cambridge. He
studied physiology, embryology, botanic.sq chemistry, and
physics (under Ptaleigh).~'- At the age of 25 he returned to
Calcutta as Bachelor of Sciences and became Professor of
Physics at the Presidency College (1885). The successftil,verifi-
cation of the Kaxwell theory of electrodynamics by Hertz
(Gerts) also gave rise to Bose's first publications and lectures.
Among others, he delivered a lecture, which attracted much
Card 1/2 attention, on the properties of electromagnetic waves (Liver-

Hu~dre~th Birthday Aimiverisary CC Djagadis Chandra Bose) SOV/53-67-1-9/12
pool, 1896). He investigated the properties of individual
parts of the electromagnetic spectrum, especially the millimeter
range (absorption, reflection, refraction,propagation). About
1900 Bose worked in the field of plant physiology, and at the
Congress of Physicists held -,t Paris he spoke about the mole-
cular phenomena caused by electric stimulants in inorganic and
living matter. Since that time, Bose remained faithful to plant
physiology until he died (23/11/1937), in which field he %as
prominent. As delegate for India he attended numerous congresses
in Europa and in Anerica. On flovember 30p 1917, the present Bose
Research Institute was inaugurated at Calcutta, of which the
physicist D. M. Bose had been the director since 1947. In
connection with Bose's research work the Russian scientists
A. S. Popovv P. ff. Lebedev, P. P. Lazarev, K. A. Timiryazey,
A. F. Samoylov and M. V. Lomonosov are mentioned. There are

herefore investigation of the modifi
of the phase angle of the electric mains circuit on the occasion of perturbations
forms the core of the Investigation of those conditions on which "inverse
operation" can be eliminated in an amplitude-phase-detector. At first the case
in which only single impulse Perturbations are active is investigated. The
spectrum of the impulse perturbation within the domain of the transmission band
of the receiver is assumed to be uniform. The bell-shaped impulse perturbation
product of the velocity of its modification at the moment when perturbation
occurs and the duration of the perturbation is assumed to be the approximated
value of the modification of the phase angle. Next, the velocity of the modifi-
cation of the phase angle of the voltage in the electric mains circuit is de-
termined, after which the conditions for the complete elimination of "inverse
operation" are examined. For this purpose it is necessary that the transmission
band of the electric mains circuit of the amplitude-phase detector be at least
from 7 to 9 times smaller than that of the receiver.
In the course of a further investigation of the effect caused by group-impulse
perturbations, it waa found that in order to reduce the probability of the oc-
currence of "inverse operation" considerably, it is necessary, by all means
available, to decrease the transmission band of the electric mains circuit of
the detector with respect to that of the receiver.

TITLE: Noise-suppression characteristics in various types of

PERIODICAL: 11ElektrosvVaz111 (Telecommunications), 1957, No.4, April,
pp.40 - 47 (U.S.S.R.)
ABSTRACT: Interference problems in radiotelegraphy reception
havebeen investigated earlier in (1-3). In (1)
amplitude and phase transmission were compared assurLg
similar methods of'detection; in (2) no adequate
theoretical assumptions were made and in (3) signal-to-
noise characteristics of amplitude and frequency-modulated
, signals were discussed very cursorily only. It is
proposed, therefore, to investigate the problem more
thoroughly for various methods of transmission, to compare
SIN ratios for the same interference powers and to
evaluate the gain in power for various types of trans-
mission. As in (1-3) the author uses the method given
by V. S. Melnikov (ref-5: Melnikov, V.S., Engineering
methods of the development of radiotelegraphy communication
systems' Compendium, 1160 years of Radio", Svyazlizdat, -
M., 1955, p.182). In this method, the final information
relating to the transmitted signal is obtained by means
of analysis of the receiver detector output voltage at
Tbr 6aide- 9-3_gn_`d1-I-eV--eY -and pas s_-::UaHd_s_f _orAM and FM-,----Yh-e.
signal-to-interference ratio at the output of FM detector
should be 1,5 times that of the AM detector output. In
phase-shift transmission, the noise produces distortion
of the transmitted information when the phase of the

ph"-~-discriminator input signal is shifted by an angle

as shown in (9,10). The final expression for the
distortion probability of phase-modulated signals is
derived as: I
2 1 1 (N
of the same form as that derived by G. F. Montgomery (3),
where 4P(N) is the probability integral for
N = Es E. being the amplitude of the "on"
~r2_,
or "off signals. The author concludes the article by a
discussion of the advantages of the phase-shift trans-
mission and states that the above analysis can be
successfully applied to other types of binary-coded
transmissions. 4 graphs illustrating the equations
derived are given. There are 11 references,*of which 9
are Russian.

ABSTRACT: The author investigates the construction of optimum
filters for rectangular, trapezoidal and triangular
signal pulse sequences and white noise. The optimum
filtering effect is expressed as a criterion of a
Fourier transformation Llqf 27. The author presents
the sDectrums of rectangular and trapezoidal pulse
sequences. He shows block diagrams for filters of
rectangular, trapezoidal and triangular pulse sequen-
ces. The calculation of the signal-to-noise ratio
at the outlet of the individual filter elements, which
were built in accordance with the author's work, are
beyond the purpose of this paper and will be the sub-

ABSTRACT: The squareof the,signal's peak ralue, the noise capacity and
their ratio at the output of the optimum filter's various elements,
were computed. The coefficient of the signal transmission, the
noise and the signal-to-noise ratio were determined by -these
.elements. It is proven that at a sufficiently wide input spectrum,
the increase in the signal-to-noise ratio by 'the optimum filter, is
equal to twice the product of the input spectrum width by the
duration of the pulse. This increase occurs as a result of a
maximum match of the characteristics of the optimum filter elements.
A diminution of the noise by the optimum filter is accomplished by

ABSTRACT: Duplex phase telegraphy (dvukratnaya fazovaya tele-
grafiya - DFT) was suggested by A.A, Pistollkors
more than 25 years ago. There is a growing interest
in phase radio telegraphy and in its practical reali-
zation in the "Kineplex" system ~Ref g. The author
therefore presents a calculation of the information
distortion probability for the DFT, since such cal-
culations were not included in the papers published
on this subject. He demonstrates the signal and
noise interaction in the DFT by a diagram, shown in
figure 1. He determines the average information

are the probabilities for coincidence of the sum
vector ends in sectors AOB, BOC and COD, shown in
figure 1. The author com ares the DFT with the
simplex phase telegraphy Mnokratnaya fazovaya
telegrafiya - OFT) and other telegraphy systems.
He emphasizes the advantages of the DFT over the
OFT and the other systems, especially in case of a
small signal-to-noise ratio. The author expresses
his gratitude to Candidates of Technical Sciences
N.T. Petrovich and N.P. Bobrov for their interest
in his work. There are 1 diagram, 1 graph, and 6
references, 1 of which is English and 5 Soviet.

TEXT: ' Probabilities are determined of correct re,-,eption of false
signalling of a periodical sequence of pulse signals with gaussian
background noise, using an incoherent build-up arrangement with an
exponential weighting function. The build-up arrangement consists
of an incoherent amplitude detector and of an adding circuit with
feedback. The feedback circuit has a delay-line of time T (the
quasi-period of the pulse repetition frequency) and a transfer coe-
fficient m < 1. At the output of the storing arrangement the volt-
age is

The determination of the exact law of distribution 3P (ZR) U(t) is
complicated. The approximate solutions may be obtained by the cumu-
lants of the n-th order of the input voltage. If the latter are
known - the cumulants of the output voltage may be determined with
the required accuracy of distribution law of the output voltage.
The distribution law UM is presented either as the Edgeworth or
Lagnerre function expansion. With square law detection the differ-
ence of U(t) expansion, compared with normal distribution is so
great that the Edgeworth series converges slowly. The Lagnerre
series permits m . 0.9 to limit the analysis to the first term only.
In this case the integral distribution law U(t) is represented by
%2 distribution, which makes it possible to determine the probabi-
lity D of correct reception and F of the false signalling. With
linear storage with m - 0.8 - 0.95 the U(t) is distributed nearly

of the Edgeworth series I-Las to be taken into account. For a suffi-
ciently high number of pulses N > 50 the threshold signals in the
square-laxwr and linear detection are practically identical. Z-Ab-

TEXTs The object of this article is to find the laws for the
distribution of the output voltages ofa non-coherent accumulator
with an exponential weighting function when the input consists of
pulse trains accompanied by noise. The apparatus (Fig.1) consists
of a non-coherent (amplitude) detector followed by the accumulator.
The accigmulator is an iritegrating device with a feedback loop
consiNfing of a delay line (with a delay T approximately equal
to t-tA tquasi-period of the expected pulsed signal) and a circuit
with a transfer coefficient of m, the value of which is constant
and less than unity. The latter prevents self-oscillation. The
pulse transfer function of the accumulator is an exponentially-
decaying train of unit pulses, repeating over the time T
