TITLE: Self oscillations in a natural circulation loop during boiling
SOURCE: Moscow. Tnzhenerno-fizicheskiy institut. leniye yadernymi energeti-

ABSTRACT: The ax)thors present the result& of an investigation of the stability of a
circulation loop by studying the self oscillations produced in two-phase systems unde:
natural circulation, at pressures from atmospheric to ten atmospheres, and heat loads
UP to 80o x 10 knaV(m2hr). Principal attention was paid to the influence of the
underheiLting of t-be water below saturation at the output in the heated section and of
the pressure in the loop on the self oscillations, on their amplitude, on their fre-
quency, and on the stability. The experiments were carried out in an experimental
stand designed to investigate the hy o4ynamics~of two-phase streams iii,channels of
various configurations. The tests consisted essentially of fiUing the~._Ptand with
feed water and heating it electrically at different rates and under various pressures
to disclose the conditions under which self oscillations in the liquid -ciirculation

set in. At constant heating, self oscillations set in at a temperature differerrtiaLj
(below saturation) of 4 - 5C., but at 10 atm the differential rose to 23 - 25C., so t
the pressure exerts a stabilizing influence. No oscillations were produced at heat
fluxes in excess of 5-50 X 1013 kcal/(m2hr) (at 2.9 atm). Conclusive results on the
stability could be obtained only at law pressures, but even these results display the
most important factors that.influence the occurrence of self oscillations in a loop
with natural circulation.* and are useful from the point of view of reactor safety.

ABSTRACT The works published on this problem offer no possibility of classi-
fying the non-linearity of the passage of the whole radio-relay
line by means of a measurement of the fading of non-linearity with
harmonice.Here non-linear distortions caused by the discrepancy of
the feeder are investigated.The author'assumes that the feeder is
homogeneous in all its length,that the reflection of energy' takes
place only from the ends of the fe6eder in conseqaence of the dis-
crepancy with the load,that the reflection coefficients are small,
and that the oscillations reflected more than once from each end of
the feeder line can be neglected.The author shows that if the condi-
tion fe is fulfilled the problem of determining the
A fm 2 cross-noises,developing in consequence of
the discrepancy of the feeder in frequency-
modulation radio-relay linea of communicatior in reduced to '.he

DISTRIBUTION CURVES
"Distribution of
Selective System
ElektrosvyazI, No
the Envelope of the Amplitudes at the Output of
Under Accidental Frequency Deviations", by A.V.
1, January 1958, pp, 9-14.
A method is given for determining the distribution curves for the en-
velope of the amplitudes at the output of selective systems owing to ac-
cidental swings of the voltage frequency. The distribution curves are
obtained for the output of resonant systems consisting of n identical
networks and n pafre of coupLed networks, under the candttion that the
modulating valte4e-has a nor=' distributicML and that the soeaUea
q~iasi-stationary solution is usecl for the output oscillations. Simple
formulas are obtained for the distribution runction of a quantity that
is the reciprocal of the voltage amplitude, and on the basis of these
formulas it is possible to calculate the probability that the envelope
will exceed a previously- specified value. The probabilities are plot-
ted for various values of both the parameters of the selective systems
and of the parameters of the messages, so as to make possible an esti-
mate of the requirements that mast be satisfied by the amplitude limi-
ters.

ABSTRACT: Based on the correlation theory of stationary random
processes, a method was developed for calculating
the power of cross noises, existing in multichannel
radio relay communication lines with frequency modula-
tion and frequency condensation. These noises are cau-
sed by the multi-beam propagation of radio waves or
by mismatching and discontinuities of transmission
lines. The formulas obtained are correct for a) two-
beam propagation - with different ratios between
amplitudes of direct and reverse waves (first casej;
b) for multi-beam propagation - if the intensity of
the reflected beams is weak compared to the intensity
Card 1/511 of the basic beam (second case). The formulas may be

used to determine cross noise caused by reflection
-within feeders. Existing papers dealing with this sub-
ject are reviewed briefly; for example that of V.A.
Smirnov Z71ef g. S.V. Borodich's formula ZR-ef 47 is
used for determining the psophometric power of cross
noises in telephone channels. The following conclusions
are presented: 1. Antennas having a high directivity
should be used in frequency-modulated radio relay com-
munication lines using the tropospheric long-distance
propagation of ultrashort waves. In this way, the de-
lay time of single beams is decreased. Further, the
probability is reduced that two powerful fields will
exist simultaneously in the region of the effective
scattering volume, whose presence is most dangerous
from the viewpoint of cross noise. 2. In conventional
radio releylines neighboring stations operate within
the limits of direct visibility. To reduce the cross
'lard noises, the communication system should be designed
Jr

Propagation
in such a manner that the intensity of each reflected
beam is low compared to the intensity of the basic
beam. 3) The relative importance of energy reflecti-
ons by the transmission line terminals and by inter-
nal nonuniformities depends chiefly on the number of
sections (number of internal nonuniformities) which
compose the line. As a rule, in practice, the coeffi-
cients of reflection from the feeder ends are greater
than the coefficients of reflection from internal non-
uniformities. For short lines only cross noise should
be taken into account produced by reflections of ener-
gy from the feeder terminals. For longer feeders, how-
ever, it is necessary to consider various other cau-
ses having an influence on the cross noise value.
These causes are reflections within the feeder, re-
flections from the feeder terminals and internal line
discontinuities, and the interaction of reflected
Card 3 beams with different delay times. The power of cross

noises caused by these factors is commensurable with
the power of noises caused by terminal reflections
with feeders of medium length; it is considerably hi-
gher with great feeder length. 4) To reduce the power
of cross noises, caused by mismatching or line dis-
continuities, first, the coefficients of reflection
of feeder terminals and of internal discontinuities
should be reduced to a minimum, then, the length of
the sections should be increased out of which the fee-
der is composed. In addition, sections of different
lengths or sections with a random spread of lengths
should be used for reducing cross noise. There are 4
references, 2 of which are Russian, 1 American and
1 English.

ABSTRACT% Transmission distortlons in vhf -tropospheric propagation
are investigated using several theories of scatter of
ultra-short waves by turbulent irregularities in the
troposphere. The basic reason for such distortions is
that due to scattering the electromagnetic field at the
receiver consists of a multitude of waves, the
propagation times of-which differ due to differences in
the lengths of the propagation paths. From simple
geometrical considerations (Ref 1), the delay time of
the separate rays in determined by Eq (1) and (2).
(The symbols used in this article are as defined in the
author's previous work, Ref 1.) With pulse transmission
some "erosion" of the leading and trall�ng edges occurs
CRef 2 and 3). A similar picture occurs with transmission

the signal like a four-terminal, band-pass filter which
has the same frequency pass-band and the same transitory
(transient) characteristics as the troposphere. From the
theories of Villars, Weisskopf and Norton, an expression
(Eq 4) is deduced for the transitory characteristic of
the troposphere (EI/Em) vhon non-directional antennae
are used. E. 1B the maximum amplitude of the tropospheric
wave for the steady-state scatter regime. Similarly~
from the theory of Steras and Booker and Gordon (Ref 7),
the transitory characteristic of the troposphere is
determined by Eq (5). Functions (4) and (5) are shown
in Fig I (curves I and 2). For comparison the
transitory characteristic from Ref 8 is drawn in the
same figure (curve 3). The shapes of curves 1, 2 and 3
do not differ significantly. On the basis of the
theories of Villars-Weinakopf and of Machmoreq the
transitory characteristics of the troposphere are derived
for the following casest
1. Rectangular directional characteristics and the
Card 2/5 antennae axes forming an angle 0.5 a0 with the

sov/lo6-59-5-4/13

hori.;ontal (Eq 8 and Fig 2).
2. Rectangular directional characteristics and the
antennae axes horizontal (Eq 9 and Fig 3).
3. Actual directional characteristic and the antennae
axes forming an angle 0.5 ao with the horizontal
(Eq 12 and Fig 4).
4. Actual directional characteristic and the antennae
axes horizontal (Eq 14 and Fig 5-71).
From analysis of -the expressions and the graphop the
following conclusions are made,~
1. The transitory (transient) characteristics of the
troposphere constructed on the basis of the different
theories of scatter approximate each other, especially
in the region of small values of the paramiter "o
I.e. for highl-y directional antennae. To
Curves construf-,ted an the basis of Tro�tsklyls theory
give a somewhat different fall in the characteristic.
2. To reduce the duration of the transitory processes
it is desirable to increase the directivity of the
Card 3/5 transmitter and the receiver antennae in the vertical

sov/lo6-59-5--4/13
Transmission Distortions in Scatter Propagation of Ultra-Short Waves
plane. To reduce distortions and to increase the powerg
antennae with high directivity in the vertical plane
and low directivity in the horizontal plane should be
used. The fundamental reason for analysis of -the
transitory processes is to determine the "establishing"
time ty and the delay time to by which is meant the time
between the step voltage at the input and the instant
that the output voltage reaches the half-voltage point.
The values of t y and to are obtained from the transitory
characteristics for the cases given earlier. From these
values the pass-band of the equivalent four-terminal
filter and its transfer coefficient are determined.
Finally, on the basis of expression for the psophometric
noise power due to non-linearity in the phase
characteristic of a four-terminal network in a telephone
channel as developed in Ref (17), an equation is
obtained (Eq 34) for the cross-talk power arising in

TITLE- Dependence of the Dispersion Power on the Statistical Charac-

PERIODICAL: Elektrosvyazl, 1960, No. 12, pp. 3-10
TEM Several theories exist to-day explaining the scattering of ra-
dio-waves by turbulent non-homogenelties of the troposphere in particular
cases. In the present article, the author develops a generalized method
taking into account all these theories and allowing to calculate the disper-
sion power in the cases cf the anisotropic and isotropic turbulence. This
generalized theory enables him to examine the dependence of the stray field
(at the locus of reception) upon the correlation function of turbulent non-
homogeneities, upon the width of their energy spectrum and upon the law go-
verning the decrease in their intensities with altitude. In the development
of Ms generalized theory, the author uses the formula giving the ratio of
the dissipated power to the power in free space, and the generalized corre-
lation function deduced by him in previous articles ("Radiotekhnika i Elek-

above enumerated parameters is less pronounced, and vice versa. 2) The cha-
racter of the 7ariations of the stray field (at the locus of reception) also
depends on the variation of the fluctliation-intensity of the permittivity of
the troposphere with altitude. The more rapid the drop of this intensity-,
the more rapid will be the decrease of the dispersion power with distance.
3) Under conditions of anisatropic turbulence, the dependence of the dis-
persion power on the various parameters does not change. 4) The magnitude
of the losses in antenna amplification is affected by the form of the corre-
lation function of the permittivity of air, by the width of its energy spec-
trum, and also by the character of the variations of (aQz with altitude and
by the degree of anisotropy of the turbulent non-homogeneities. Formulae
