ABSTRACT: For calculation of the springs used in injection nozzles the
author uses the theory of a longitudinal shock wave traveling
along an elastic rod: the SDring is replaced by an equivalent
straight bar, the mass and deflection - per -iinit-I oad of which
are equal to the corresponding parameters of the spring.
Formulae are evolved for determining the strain rate and the
time required for a deformation wave to complete a single for-
ward and return trip over the length of the rod. A determina-
tion is made of th6stresses in different sections of the spring.
The discrepancy between the calculated stresses and those
determined experimentally is of the order of 5-656.

ABSTRACT: Studies of the function of external respiration during alpine acclimatiza-
-tion in the mountains of the central Tien-Shan range, and of gas metabolism
in pressure chamber atmospheres equivalent to altitudes of 6000 to 9000 m,
,are reported together.
Gas metabolism was studied in 35 accomplished alpinists climbing Ehan-
Tengri Peak (6995m), and*' in 22 'members of a scientifi-c
expedition to Tuya-Ashu Pass (~300 m).
Pulmonary ventilati= and vital capacity were recorded and basal me-
tabolism during dosed exercise (bicycle ergonieter and ascent up the moun-
tain side) was studied in selected individuals.

ACC NR:
Pressure chamber studies included determination of the 02 and C02
content of alveolar air.
During 40 days in the mountains (elevaiion 4200 m): a) vital capaciti.
was constant during the stay at the base camp and during ascent of the moun-
tain; b) respiration frequency increased to 19 respirations /min during the
-first days in.the mountains (3000 m); respiration frequency declined some-
what during acclimatization 66'16' or' 17'per minute resting up to 7000m;
C) depth of respiration was about 700 mg during the entire stay in the moun-
.tains; d) resting minute volume increased by about one-third on arrival in
jhe mountains (from 9 liters/min to 12 liters/min), remaining at that level
;during the whole period of acclimatization; e) the time the breath could be
held, after exhalation and especially afier inhalation, was less than at sea
.level; f) immediately after descent from the -mountains, basal metabolism and
external respiratory functions returned to initial values.
Observations of gas metabolism during dosed physical e:~ercise at. -
3300 m showed that the 02 requirpment of alpine natives is different from
that of visiting plains dwellers. On the.�icycle ergometer (1000 kgm/min),

ACC NRt AT6036546
plains dwellers performed a greater quantity of work but had a higher
oxygen requiroment (2604 mllmin against 2080 ml/~in for'mountaineers).
In a timed climb up the mountainside, the mountaineers climbed 4/3 times as
fast on less oxygen (1243 ml/min against 1894 ml/min for the-plains
dwellers). It was concluded that mountaineers utilize oxygen more econorni-
cally during alpine exercise.
Studies of tolerance to pressure chamber altitudes before and after al-
pine acclimatization showed that: a) respiration frequency changes little
during "elevation" to high altitudes; b) changes in vital capacity were ir-
regular; c) the length of time the.breath could be held atan altitude of
7500 rn by persons fairly well acclimatized was half the sea level value;
d) alveolar P02 and PC02 decreases as elevation increases, and also during
continuous exposure to one elevation; at 7500 to 9000 m, alveolar pO?, fell
below 30 mrn Hg and PC02 content to 12 to 14 mra Hg; e) due to greater
alveolar ventilation, blood oxygen saturation fell off during elevation to high
altitudes considerably more slowly after alpine acclimatization than before-

PERIODICALs Radio, 1958, Nr 4, PP 34-37 (UBSR)
ABSTRACTs Two superheterodyne receivers which are built around a mini-
ature triode-heptode tube are described. In this tube the
grids have no internal connection and the two parts of the
tube can therefore function quite independently. The first
receiver i8.a heterodyne with mixed antenna coupling for use
on medium and long waves. The heptode is used as a frequency
convertor and the resultant IF signal, after detect-Jon by a
diode transistor, is,fed back to the heptodets grid, which
then acts as an AF amplifier. Finally the AF signal is fed
into the triode output section and goes from there to the
loudspeaker. The set is powered from the mains via a diode
rectifier. The construction details are given and coil and
transformer winding data, together with tuning techniquej
supplied. The second receiver is a 2-tube heterodyne, this
time with a powerful pentode output stage, which makes it
suitable for use as a phonograph amplifier, Capacitance

TITLE: Nsw Phototelegraphic Communications Equipment (Iqovaya

PERIODICAL; Elektrosvyazlg 1958, Nr 97 pp 36 - 43 (USSR)
ABSTRACT: The use of phototelegraphy for purposes other than sending
news-pictures by wire or radio has been hindered by a
number of reasons: 1, the low channel cal~~Lcity of
facsimile equipment compared with strictly telegraphic
inethods5 2, the complication and expense of facsimile
equipment caused by the cost of materials and processes;
3, the cost of the ~eTminal equipment itself; 4, the
difficulty of relaying telegrams at transfer points. In
recent years apparatus has been developed in the Soviet
Union which finds wide application and to some extent
overcomes the above objections. First considered are the
F TAM and FTAYL-2 equipments intended for high transmi ssior.
speed and high reproductlon quality. Until now speeds
have been limited to 1.20 lines/minute with a line length
of 210 mm. The main cause of speed limitation was phase
Card 1/6 distortion. This has now been corrected by the intro-
duction of a 300 - 3400 cls phase corrector of standard

SOV/106-53-9-6/17
New Phototelegraphic Communications Equipment
type as described by Davydov in Ref 1. The use of this
corrector5 together with single-side band transmission,
has enabled speeds to be increased by two and sometimes
three times. The FTAM set works at 360 lines/minute and
has been described in more detail in Ref 2. The F TAYL-2
set is more up-to-date and is easier to make and exploit.
It works at 250 lines/minute with 5 lines/mm. The
characteristics of the special transmission line filter'
with which it works are shown in Fig 1. The trans-
mitting and receiving portions of the set are housed in
separate bench mounting units. The sending portion is
shown in Fig 2. Half-tone control is provided in the
recording equipment and operates both.in the dark and
light areas of the image. Fig 3 shows a typical charac-
teristic of received vs. transmitted optical densities
when using standard production paper YHlb POM -3 with a
sensitivity of 12 GOCT units. Phasing is carried out
semi-automatically with the-aid of a small cathode-ray

recent years there has been an increasing tendency to
;3end by wire plain text, drawings, synoptic charts and so
on. This material is well adapted to reproduction on
moist electrochemical paper such as EXb -3, capable of
6 gradations of density. The FTAP equipment makes
use of this paper in a system intended for use in inter-:
urban and cross-town con, mnications where there is a larie
daily volume of telegraph traffic. Figs 4 and 5 show the
transmitting and receiving parts. Half-tone images may
also be sent where the standard of reproduction needs to
be "artistic". Figs 6 and 7 compare the same image
recorded on photographic and electro-chemical paper
respectively. When the turminal equipments are fed from

the remote supervision of the transmitter. Leading
particulars of the FTA P set are: The image is produced
flat on a continuous roll of paper 220 mm wide from a
mechanism involving an oscillating mirror driven by a
cam; spGad, 120 linos/minute; scan step, 0 2 mm; inter-
action modulus$ 3.1/~O; carrier frequency, 1906 als; length
of paper in the roll, 30 m; supply 50 cls at 127 or
220 volts.. The development of methods of "open" recor-
ding has also led to the introduction of much simplified
apparatus for sending simple diaerammatic material. The
cost of such apparatus compares favourably with that for
ordinary start-stop tape equipment. Moreover there is no
need for highly trained personnel to operate it. Fig 8
shows the recently developed "Rekord" set -%-.,hich may be
used either as sender or Teceiver. It is intended for
cross-town or internal system worldng and uses ordinary
telephone connections. Autoiaatic gain ~-oatrol takes caTe

The recording means is electromechanical using Coloured
telegraph paste on ordinary paper. The leading particu-
lars of the "Rekord" set are., drum diameter, 70 um,
drum length,-150 mq speed, 120 r.p.m; scan pitch, 0.2
mm; interaction modulus, _150; carrier frequency. 1900
C/S; supply, 50 cls mains at 127 or 220 volts. When
sending single-spaced typescript the effective sending
rate is 1+00 symbols/minute. Fig 9 is an example of a
drawing sent by the system. At transit points in a
communication system the problem of multiple reception

TITLE: A Three-tube Superheterodyne (Tr'e'khlampovyy supergeterodin)
PERIODICAL: Radio, 1958, Hr 9, PP 43 - 44 (USSR)
ABSTRACT: The receiver covers SIV 19-65 m, MY 187-578 m and LW 750-
2,000 m. The IF is 465 kc. The receiver has a rated out-
Put of 0.5 va and sensitivity is around 300/kv in the MV."
and LIV bands and 50OAv in the SW band. There is induct-
ance antenna coupling in the SW bandl for MW and LW re-
ception a magnetic antenna is used with capacitance feed-
back. A push-button unit is used for wave-changing. To
use the set as a grammophone amplifier, the MW and LVI
keys are pressed simultaneously, thus cutting out the in-
put circuits and thereby radio reception. The two sections
of the lst heptode-triode are used respectively as mixer
and heterodyne, those of the 2nd as IF amplifier and 1st
AF amplifier. The detector is a DG-Ts4 transistor diode.
Card 1/2 The final stage is a pentode output amplifier with nega-

tive feedback. The power unit uses junction-type germa-
nium diodes as doublers. Constructional details and coil
winding data are supplied. There are 2 sets of diagrams,
1 table, 1 circuit diagram and 2 figures.

"Estimation of Tolerances for Deviations of Frequency Characteristics of Phase
Delay Time and Attenuation in Communications Channels for Transmission of
Pulse Signals"
Moscow. Elaktroavyazl, No 6, 66, pp 10-19.
ABSTRACT: An analysis of the tolerance for small deviations of frequency cha-
racteristics of attenuation, phase and delay time of communitations channels
on distortion of-signals transmitted through the channels, It Is established
that the tolerances fordeviation of phase and 4clay time characteristics
should be characterized not by the deviation amplitude, but rather by the area
of the figure formed by the modulus of the characteristic and the frequencies
axis within the transmission frequency band. Orig. art. has: 13 figures and
11 formulas. EJPRS: 37A.791

Rodents, those of the Otrbillinae subfamily in particular, cause ex-~
_tensive damage to pastures. They are also carriers of Ixodes ticks which"
..':1ifest farm stock, causing various diseases in the animals. As a result
iDf experiments conducted at the Saratov Institute "Mikrob" of the KWIC-
-try of Health USSR and at the, All-Union Institute for Plant Protection
jt was found that bait poisoned with zinc phosphide and distributed over
ilie fields by plane or by hand was highly effective as a means of control--
ling the pests.
Similar experiments conducted at the Institute of Zoology and Para-
~:._*#ology of the Academy of Sciences Tadzhik SSR by the author in cooper-'
with collaborators M. A. Gulyayeva, S. A. Saidaliyev, and Yu. M.
lov, and I. V. Fadeyev, representative of the Administration for Plant
of the Ministry of Agriculture Tadzhik SSR, confirmed these

The poisoned bait was prepared in the following manner: d
~00 kilograms capacity was filled with 25 kilograms of wheat to which
~0-5 kilogram of cottonseed oil were added as an adhesive. Then 1.5 kilo--!!~
.,Vams of zinc phosphiae were added; the contents of the drum were thor-
'~-.*Ughly mixed, and scattered over the pasture at the rate of one kilogram
of the poisoned wheat to one hectare of pasture land. The poisoned bait,
remained effective for a period of 10 days, killing 72.9 percent of the
f!odents infesting the field. The experiments also established that the
~~'exiation method of distributing the bait was less expensive and more ef-
fective than the method of -placing the bait,d.irectly into the burrows of.

fOSTRACT: The author proposes the following simple method of
establishing the relationship between the phase and group
velocities. Let there be two waves with wavelengths
W "%). '41 which are propagated with velocities Vl > V in
tL"direction 011. It is assumed that the peaks of the
two waves (amplitudes Al and A) coincide? at a certain
time, at a point 0 (Fig 1). The next coincidence of
the peaks will occur at a point 01 (Fig 1) on super-
position of two peaks which are at the moment on the left
of the point 0 at distances Xl and ), from it.
Consequently the velocity of propagation of the "energy
centre" of these waves, i.e. their group Ve'00'tY7 is
