TITLE: The heating of overhead lines by solar radiation
PERIODICALs Izvestiya vysshikh uchebnykh zavedeniy. Energetika,
no. 7, 1962, 31 - 33
TEXT: A simple and fairly precise relationship is obtained
for the temperature rise due to solar radiation on a current-carrying
conductor. Curves describing the permissible loading on a conductor
heated also by solar radiation, expressed as perceyitages of -the per-
missible loadings without solar heating, demonstrate that when tempera-
ture rise due to solar radiations is 50C the continuous permissible
loading must be reduced by 5 - 7 %, when it is 100C by 11 - 15 %, when
it is 150C by 17 - 24 % and when it is 200C by 23 - 33 %; the first
figures refer to an air temperature 2000 and the.second to 350C. Final
temperatures calculated for different air speeds and temperatures indi-
cate that the conductor temperature rise due to solar heating is approx-

in calculating the final temperature are within 2 - 3 %. There is 1

"Mutual Synchronization o' R=,Plex

Trofimenko, Radiotelthnika i Elektronika, 'No 8, August 1957, PP. 1046-1D52.
The purpose of this e*xperimental investigation was to obtain a wide band of
electronic frequency retuning. The authors have establLshed the region of the
values of fundamental parameters, in which klystrons operate in synchronism
without discontinuities in amplitude and frequency of.thezgenerated oscillations.
The resultant range over which electronic frequency detuning to possible Is three
times greater than obtained vith a single klystron. Although the simultaneous
operation of Klystrons was already considered previously by Abdel Dayen (~-)'ynehro-
nization of Reflex Oscillators, Zhurich, 195,"), the mutual synchronization studiled
there was under identical transit angles, and the purpose of that iln7estiga-tion
vas an incraase in the general output power in the center of the oscillation
reglon. The problem of extending the fange of electronic returning of the
generated of the generated frequency was not touched upon there at all.

ABSTRACT: A travelling wave tube (TWT) connected across an ex-
ternal feedback circuit may be used as a i~enerat'or of
u.h.f. vibratiDns (Refs.1 vid 2). The frequency of the
vibrations is determined by a resonator in the feedback
circuit. Such a generator has been used by the authors
in the 3 Cm region in. the observation of electron para-
inve~. ti -ation
niagnetic resonance. The specimen under I I ~
(dinhenylpicry1hydrazyl) was placed directly in the gen-
erator circuit and in the electromagnet gap. The uniform-
ity of ~he external magnetic field vras sufficiently high and
had no effect on the form of absorT)tiOn lines., The absorp-
t-ion signal w%,as detected by a crystal detector 'placed in the
feedbac.k. channel. As the feedback is reduced and the oscill-

TITLE-,, Frequency-division at Ultrahigh Frequencies by Means
of Travelling-wave Tubes
PERIODICAL: Izvestiya vysshikh uchebnykh zavedeniy,
Radiofizika, 1961, Vol. 4, No. 2, Pp. 309 - 318
TEXT. The problem of developing efficient and reliable
frequency-dividers for the UHF range is still considered to
be unsolved, in spite of the need for such devices. Frequency-
dividers for these frequencies can be based on the same
principle as those employed at radio frequencies. In general,
it is required to develop dividers having comparatively large
operating bandwidths. The authors are of the opinion that a
a travelling-wave tube (TWT) with separate helices (see Fig. 1)
can be used as a frequency-divider for UHF. In this device the
electron beam passes through a number of helices which are
used for wide-band amplification of different frequencies; the
potential of each helix is chosen so as to obtain optimum
interaction between the beam and the helix. The tube of Fig. 1
Card 1/8

s/14i/6l./oo4/oo2/oil/0l7
Frequency-division E192/E382
consists of; I - electron gun; 2 - electron beam; 3, 4, 5
and 6 -- delay helices and 7 - collector. The signals to be
amplified can be applied t6 the inputs of various helices;
in the same way, it is possible to effect mixing or multi-
plication. The separateportions of the tube can be bridged-over
with external feedback circuits~ The preceding "stages" can
be used for :injecting the signals which interact with the
oscillattons of the system. It is possible to eliminate almost
completely the effect of the oscillations on the signal. A
TWT with separate helices should, therefore, result in a
flexible device permitting an efficient mixing of signals
and it should have some advantages as compared with
klystrons (Ref. I - Ye.N. Bazarov. M-Ye. Zhabotinskiy,
Radiotekhnika i elektronika. 1956, 1, 680; Ref. 2 - H. Lyons
J, Appl. Phys,,, 21, 59~ 1950). A regenerative frequency-
divider and a resonance frequency-divider based on this type
of tube were investigated experimentally. The regenerative
fz,equency...divider or, mixer gave a division ratio of 3:4, the
input frequency being 4 200 Mc/s. this tube was in the form of

a two--helix TWT. The first helix of the tube was used for
wideband amplification (bandwidth of 600 mc/9) of signals at
frequencits around 4 000 Mols- while the second helix was
employed for the ampli.fication of signals in the frequency
range .1 500 - 1 000 Mc/s. The signal and the local oscillator
frequencies were applied to a common waveguide which was matched
with the first helix; this helix was terminated with a matched
load, whose function was to eliminate any tendency to self-
excitation. The difference-frequency signal was obtained by
means of a coaxial cable, which was matched with the output of
the second helix. In the design of this frequency-divider or
mixer attention was paid to the investigation of its transfer
coefficient and its operating bandwidth. The experiments showed
that it was possible to obtain operating conditlons under which
considerable gain could be obtained in the process. The trans-
fer coefficient was between 15 - 20 db (and even 30 db) over a
wide range of frequencies (a bandwidth of 4oo Mc/s). The
frequency characteristics of such a mixer are illustrated in
Fig. 2~ This shows the transfer coefficient of the mixer as a

function of the input frequency f signal and the difference
. I
frequen~~--y f2 The local oscillator frequency for the
experiment illustrated in this figure was f !r = 4 225 Me/s:
the collertor current for the Curve(a) was 1.1 mA and for the
other -curve it was 1.8 mA. It was found from the experiments
that the value of the transfer coefficient increased with
increasing collector currents; however, at comparatively large
currents it was possible to observe the regenerative effect.
Optimum conditions with regard to maximum efficiency of the
signal mixing were achieved when the operating voltage of the
first helix was about 30 - 40 V lower than that corresponding
to the maximum of the TWT gain. The overall conversion gain
exceeded the gain of TWT in both the helices by at least 5 db.
auffi as/
It had been shown earlier by one of the or (Ref. 7
Radiotekhn.ika i el,ektronika, 19W 5, 1736) that the parametric
effe::tz- could play a significant paM in the operation of a
TVr mixer, The difference-frequency of the mixer corresponds
to the differen,_--e -frequency of a travelling-wave parametric

amplifier.. In fact, the parametric-amplification conditions
represent an optimum for a TWT- mixer. Consequently, the
magnitude of the mixer transfer coefficient can be estimated
on the basis of the formulae derived for the parametric wave-
guide amplifying systems (Ref . 5 - P,K,, Tien - J. Appl. Phys. ,
29, 19581 1347',, Ref. 6 -W. Loisell. G. Quate - Proc. IRE, 46,
707, 1958, Ref. 8 - W. Loisell - J. Electron. and Control, 6,
1, 1959). However, the overall transfer coefficient in an
acx.ua.L TWT mixer Is determined by the frequency-conversion
proce3s as well as the gain in the first and second helices.
The second divider is based on the resonance of the second kind
and the harmonic locking effect. An experimental tube of this
type was constructed. The first helix of this tube was used
for injecting the signal to be di%rided into the electron beam,
the frequency being 2f = 6 000 Mc/s; the second helix formbd
a delay system with an external feedback and was tuned to the
frequency of f ~ 3 00o Mc/s.. The frequency of the oscillator
wasprimarily determined by the resonance frequency of the
resonance circuit in the f6edback loop: which suppressed the

undesired oscillation modes. Depending on the damping of the
aitenuat.o.-,, whichwas connected in the feedback circuit., the
operating conditions of the Wrcculd be such as to produce
oscillations or potential instability (resonance of the second
kind). This system has two advantages as compared with a
klystron divider. 1) the signal to be divided is introduced
into the electron beam by means of a separate helix and this
results in an effizient interaction between the signal and the
tube and permits a 40-50 db decoupling between the tube and
the signal sources 2) the relative frequency drift of the
divider can be made smaller than In the"~lystron.. In particular.,
thi.5 d-ift can be made as low as 3 X to if the tube is
supplied from a battery and the effective quality factor of its
resonator Is % = 3 x 10' . The above results show that
TWT frequency,dividers with separate helices have considerable
adirantages!. in particular- it is possible to obtain large
operating bandwidths. On the other hand, it should be pointed
out that the harmonic locking effect and the resonance of the

n-th kind is probably of little use in practice since this
type of frequency-division can be efficiently performed by
semiconductor diodes with nonlinear capacitance (Ref. 10 -

ABSTRACT: The eastern Ciscaucasia represents an alluvial-delta
plain sloping from 300 m down to 26 m from southwest
to northeast. Its western part is covered with
ancient alluvial loess-type loams and clays which
usually contain carbonates. The eastern part is made
up of vriarine deposits. The climate is arid, with an
annua' precipitation of 290 mm in the east and 400 mm

the first half of the summer. The western steppes, covered with
different kinds of grasses and cereals, change in the east either to
steppes bearing cereals or to deserts with wormwood and grasses or
with wormwood'alone. The western dark chestnut soils change corre-
spondingly to chestnut and light chestnut soils in the east, and to
brown soils toward the shores of the Caspian Sea. The soil cover is
characteristically varied (chestnut, solonetz, and solonchak soils).
The author notes that the chestnut soils of the eastern Ciscaucasia
are thicker than similar soils found in the southern and southeastern
USSR. This is due to the less continental climate, to the high
carbonate content at the surface, and to the absence of compacted
layers (except in light chestnut soils with various degrees of sa-
linity). At the present time ground water lowering and biological
desalting are placing the solonchak and solonetz soils of the
eastern Ciscaucasia in the realm of relict features. A bibliography
of 41 titles is included.

TITLE: On the Theory of Vibroprobes with Electrets
PERIODICALt Pribory i tekhnika eksperimenta, 1961, No.2, pp.166-169
TEXTt Electrets are sources of a constant electric field and
can be used in instruments, the operation of which is based on
inducing an a.c. current in the field of the electret. Several
designsof electret vibroprobes are described in literature but,
according to the author, the theory of their operation has not been
evolved. Fig.1 shows a diagrammatic representation of an electret
between two metallic electrodes A and G which are connected
through an external resistance R(Ishort-eircuitedlelectre t). On
the basis of electrostatic formulae, the following relation is
valid
a = (I 0/(g E/L +
where a is the density of the charge induced on the electrodes,
a electret surface charge density, L - "electret thickness'*,
the gap between the electrode A and the surface of the
electret. In the case that the electrode A vibrates relative to

be expressed by the following equation

1) 0
where R is the external resistance of the circuit R - internal
capacitive reactance of the short-circuited electret. 0 Eq.(2) is
the basic equation characterizing the operation of various electret
instruments (microphones, telephones, vibration probes etc.).
Accordingly, the voltage on the input resistance is proportional to
the relative speed of displacement of the electrode A. In order
that the output signal is proportional to the relative electrode
displacement and not to the speed, it is necessary to integrate
Eq.(2) with time. By differentiating Eq.(2) with time we obtain
an output signal that is proportional to the relative acceleration
of the mobile electrode. The sensitivity of the vibroprobe as
regards acceleration can be expressed by

the electret surface, the air gap between the membrane and the
electret surface was 0-015 cm. A thin brass foil was used as a
second electrode. The membrane was connected to the metallic
body A which was grounded; from the second electrode a lead D
to the external circuit was provided. The surface density of the
electret charge equalled 2 x 10-9 Coulomb/cm2. The signal was fed
to the input resistance of a tube voltmeter with R = 2 megohm.
The experimentally determined resonance frequency of the mobile
electrode f equalled 1650 c.p.s. Good agreement between
calculated ana experimental results were obtained. Fig-3 shows
the sensitivity of the vibroprobe with respect to acceleration N
(mV/g) as a function of the vibration frequency (C.P.S.), It is y
pointed out that electret vibroprobes operate without external
supply sources and, in contrast to electromagnetic probes, the
alterndting current is induced by the electric field and not by the
magnetic field. If the system, electret system-mobile electrode,
is considered as a plane condenser, a certain analogy can be
arrived at between electrets and capacitance probes, the main
difference being that capacitance probes require an external field.
