ABSTRACT: To obtain an Fe-Cr-Ni-Mn steel with a yield strength higher
than 80 Yg/R=2 by heat treatment without strain hardening, the effect
of C~I.N*"'and V`6n thO strength. ductility, and notcb toughness of
Istalmless Kbi-7002541ase steels, has been Investigated. The steel a Ini
ivestigated containeA 16.50-IT.90% Cr. 3.82-4.6o% vi, 14-T0-16-17%
Mn, 0.02-0.43% C, 0.015-0-45% V. and 0.1-3-12% V. The beat treat-
ment consisted of quenching from a temperature in the 1150-1200C
irange and subsequent aging. It was found that, as auntenite-forming j
:elements, C and I affect the steel structure in approximately the same

degree. Steple without V are austenitic with the C or N content
higher than 0.91%, but this amount should be Increased to 0.27 and
0.37%, respectively, to preserve the austenitic structure In steels
with 1-2% V, Alloying with V promotes, formation of a fine-grained
etructure and a more uniform distribution of carbide and carbonltrlde~
phases. It slightly increases the strength characteristics of the I
steel and sharply increases the strengthening effectiveness of agi "51
The maximum strength with aging was achieved in a steel with 0.40 to
2% V. In the steel quenched from 1150C, 10-hr aging at TOOC increased
the tensile strength from 85 to 98 kg/mm2 and the yield strength frool
55 to 73 Waal but decreased ongation from 25 to 12% and the notchl
toughness from 965 to 7.0 kgn/:212. The best combination of strength
ductility, and notch toughness Is achieved by combined alloying of
steel vith C, N, and V; moreover, substitution of N for C improves
the anticorrosion properties of the steel. The steel strengthening

Periodical s Radiotekhnika 9, 21-30, Mar/Apr, 1954
Abstract : Considers calculations of signal pulse form distortions during
transmission through a minimum-phase linear system If only the
frequency characteristic is known. The distortion factor of signal
form as a whole and the time lag of the signal are used as quantitative
measurements of distortion. Also shows that spreading the character-
istics of the standard frequency response passband causes an automatic
improvement of the form of its phase response. Six references: 6 USSR.

Abstract : In connection with the importance of pulse-code modulation to multi-
channel radio relay lines used for communications, television, navi-
gation, and remote control, the authors examine the character of
the spectrum of signal harmonics and combination frequencies de-

ABSTRACT: The input signal is mixed with a local oscillation
whose frequency may be controlled by a voltage. The output
of the mixer is fed via a tuned amDlifier to a discriminator,
the cross-over frequency of the diieriminator and the centre
frequency of the amplifier being the same. The voltage
pulses out of the discriminator are amplified and fed to the
diode-phantastron circuit. In the absence of discriminator
output, the phantastron produces "a saw-tooth voltage waveform,
causing the local ossillator to search" over the frequensy
scale. The grid of the phantastron is returned to earth via
the diode, connected as a d.e. restorer. Discriminator nulses
appearing across the diode produce a negative voltage which
stops the aear2h. The anode voltage of the phantastron is now
dependent on the voltage at its grid and behaves like an
ordinary "integrator". The following assumptions are made in

the analysis of the circuit:- within the working limits, the
discriminator characteristic, the control characteristic of
the local os:.--4llator and the anode-grid relation of the phant-
astron valve when used as an amplifier are all linear; the
pulses are rectangular; distortion suffered in transit through
the narrow-band and video amplifiers are neglected; the diode
charac,teriati: is piecewise linear. Since the relations in
the rest of the loop are independent of time, interest is
eentred on the behaviour of the control circuit. Analysis Of
the circuit of Figure 4 yields equations (9) and (10) which
des-Iribe the way in which the &rid voltage of the bantastron
varies in the iaterval between pulses. Eqs.(13), M) and (15)
give the deviation of local oscillator frequency from nominal
value and the time-rate of change. Because of the periodic
nature of the signal the local oscillator frequency will also
have a saw-tooth variation. The tuning error is defined as
the peak deviation of local oscillator frequency from the
cross-over point of the discriminator and is given by Eq.(20~
This error will be the less, the higher the video gain and

TITLEt Increasing the efficiency of multichannel systems with time division
of channels
PERIODICAL: Blaktroavyazl, no, 5, 196o, 10-16
TEXT: Statistical measurements In multichannel systems with time division
of channels revealed that a telephone channel is really active only for about 15
minutes per hour at maximum load. The probability law proves that during 99% of
the total time the number of active channels does not exceed a value n < N
(N being the total number of channels). The present article shows how it is
possible to increase the efficiency of these multichannel systems by a proper
use of inactive intervals and channels. It also shows that this efficiency can
be increased by a more complete utilization of the statistics of the Instantaneous
values of the transmitted signals: by varying the duration of the channel inter-
vals in accordance with the instantaneous value of the transmitted signal, it is
possible to Increase the number of channels. To enhance this efficiency, it is
necessary to abandon the channel Interval of constant duration. Inasmuch as

the time Interval between pulses of the preceding and following channels is used
as carrier of useful Information, the method described by the authors Is a
variety of pulse-time modulation and can therefore be named "Interval pulae-time
modulation" or IPTM. There are many possible variants of this new type of
modulation system, but all these variants can be divided Into defknite categories
according to: 1) the method used for transmitting the number (n-)-of the channel
2) the method allowing to take into account the sign of the modulating signal.
Let us assume that the voice signal((t) is a stationary random process with
~2
probability density w (x), with zero mean value and with dispersion 6t. Let us
analyze e srstems where the information Interval is modulated by the absolute
valu ir(t) of the signal in a given channel, and where the sign of the signal
Is coded by an additional pulse. If tV Is the random duration of the Information
interval of the I -th channel, the probability density of tV Is:
W (X) . 2 w (x X> 0 W
h D'
where h is the proportionality coeffinient(which will be assumed equal to one).

In the case of IPTM where information Intervals are modulated by the sum of the
instantaneous values of the signal and by its envelope E (t), the mean value of
tv is: M, ttvj - (t)~ + M, JE (t)~. (4)
and the dispersion -
.2 ts .I ' M2 (t) i + M2 [E (t) (5)
To compare the efficiency of several variants of the system using IPIM, the gain
procured by any one of these variants (as regards the number of channels and the
frequency-band) In respect of the usual pulse-phase modulation systems Is to
be calculated. In the usual N-channel pulse-phase modulation, Interval To Is the
sum of N + 1 channel-intervals (account taken of the synchronization channel)
The duration of one channel-interval Is the sum of pulse 'Z, of the proteetiv;
time 3 T and of the duration of the Information interval 2 cz, 6. The magnitude

of the peak factor c61 is derived from the condition that the absolute values do
not exceed (with a given probability p ) at e Thus:
To= (N+ 1) (41C +12*cf, 16). (7)
Let us now analyze the time Ti occupied in one period by N, channels of the I"I
system (Abstracter's note: Subscript I stands for any one of the compared
variants of the system.]. If BIT- is the duration of the code combination of
pulses per channel, T1 is the sum of the time (BiSI + 2)j; occupied by code
combinations and marker pulse, and of the total Information time equal to the sum
of n independent, similarly distributed, random magnitudes. Si is here equal
to tL number ni of active channels In the case of a special coding of the numbsr
(no) of the channel, and to the total number Ni of channels in the case of a
simple reading of channels. If the number of active channels is, with a proba-
bility near one, not Inferior to ten, the total information time can be considered
as distributed according le
~Oh t,,jormal law(VT the mean and the dispersion

At the end of the article, the authors, using the above set of formulae, compare
the efficiency of the different variants (1) of the IPTM system. They find that
the least efficiency corresponds to the coding of the number (no) of channels by
a uniform binary code. With a non-uniform binary code, the minimum efficiency
(1.75-times increase of the number of channels) is yielded by the system with the
additional, sign indicating, signal, and the maximum efficiency (1.91-times In-
crease of the number of channels) is yielded by the transmission of the sum
(signal + its envelope). The greatest efficiency (4.15-times Increase of the
number of channels) is obtained with the simple reading of channeli and the
transmission of the sum (signal + its envelope); this method ensures also the
maximum narrowing of the band for the same number of channels. There are 5

however, require knowledge of an &-priori probability p (I); this limitatiun is
very important in a communication system. Detectors with an extremal search
system of threshold control permit determining the optimal threshold in the cases
when error-detecting codes are used and when p (1) is unknown. The time of
determining the optimal threshold is longer (because of the time lose for
searching) than in other types of detectors. Besides, the searching may cause
errors in the setting of the threshold level, the errors increasing with the signal-
to-noise ratio; in this case, the radius of curvature of the control -performance
function increases, and with the increasing signal-to-noise ratio, no Proportional

TITLE: fGw___fn_au__ct_i_o_n`and Tribo-induction Electrostatic Generators
PERIODICAL: Pribory i tekhnika eksperimenta, 1959, Nr 5,
pp 80 - 85 (USSR)
ABSTRACT: The induction type, which is seen in Figure 1, in
illustrated by Figure 2. The system can provide up to
50 kV at up to 0.1 mA (Figure 3 - the various lines relate
to different speeds of the driving motor; the numbers
on the curves are the voltages Applied to the motor). The
points (brushes) on the collectors C have the function
of transferring the charge to the insulating disc (which
carries no metal strips). The system is very much that of
a sophisticated Wimahurst machine; it works on the
principle of the electrophorus. The polarity of the output
is determined either by charging the disc appropriately at
the start from a low-voltage source or by using frictional
methods (these methods are used to generate the charges in
the second type).
Figure 4 shows a development from the system of Figure 2.

of the load curve at the working voltage has been reduced
from 2 IcV/$LA to 0.8 kV/UA (System III has a single needle
instead of a brush; otherwise, it is the same as System II).
Figure 6 shows the operation of the friction part of the
second type of generator; this systvin is used-only to
provide a high voltage for a machine of induction type,
since the load curves for the two output polarities are
poor (Figure 7). Figure 8 shows a generator of this type
giving outputs of both signs; Figure 9 shows the system
used, with the friction source on the left. Figure 10
resembles Figure 3; this instrument is pressurized (P is
the pressure in atm.)4 This latter design allows of
electronic stabilization since the output voltage can be
coupled to a triode that controls the current to the charging
brushes. Figure 11 shows a system designed to give outputs
of both polarities. There are 11 figures and 23 references
10 of which are Soviet, 7 German, 2 French and 4 English.

Electron multipPer with an axially symmetrical M at
window of 24 cm area
PERIODICAL: Pribory i takhnika eksperimenta, 1961, NO-3,PP.157-158
TEXT: For recording wide beams of recoil nuclei, electron
multipliers are required with an as large as possible area of the
cathode from which the recorded particles eject electrons. Fig.1
shows a sketch of the electron multiplier. In this paper an
electron multiplier is described, the cathode of which is in the
shape of a hemisphere of 60 mm diameter with a central opening of
10 mm diameter. Along the axis a short 6 mm diameter cylinder in
placed which is electrically connected with the first dynode.
In the gap between the cylinder and the edges of the cathode
opening, a ring,with welded on 0.15 mm diameter tungsten wires
which are located along the generating lines of the 8 mm diameter
cylindrical surface inside the cathode cavity, in fixed onto glass
insulators. A potential slightly higher than the cathode

potential in fed to the wire 'Icylinder'l and this produces an
additional field that accelerates the electrons which are released
from the cathode surface by the primary particles so that the
collection of electrons from the peripheral regions of the cathode
into the dynode system is considerably improved. To eliminate
field distortions in the cathode cavity, the inlet window in
covered by a grid to which an independent potential can be fed.
Electrons from the cathode, which come into the near-axial region
of the cathode with only low energies (due to the accelerating
field produced by the wire cylinder), are under the effect of a
strong focusing field of the cylinder of the first dynode which
collects them onto the active part of its surface. Then follown
the ordinary process of multiplication in the dynode system, which
has 17 dynodes instead of the usual 11 in the type IC (18)
multipliers. The cathode and the dynodes; aro made of an Al-Mg
allay with an addition of silicon with thicknesses of 0.2 mm and
0.1 to 0.12 mm, respectively. Activation is by alternating

important advantage of this alloy against other alloys (Ag-Mg,
Cu-Mg, Cu-Al-Mg, Cu-Bo) is its reactivation after standing in air
(heating in vacuo at 340*C for 30-60 min). The operation of an
electron multiplier is as followni onto each section of the
cathode a narrow, 8 mm wide, beam of a-particles is directed and
the number of pulses at the output is recorded. Fig-3 shows the
focusing curves (N - pulses/see) taken on displacing the source
along the cathode diameter. The half-width of the curve equals
55 mm (which coincides with the diameter of the inlet window) but
does not change on ehanging the efficiency of the recording of the
a-particles (curves 1, 2 and 3 were recorded for a-particle
recording efficiencies of 100, 45 and 19%, respectively). The
beat amplitude distribution of the pulses (Fig,4) was obtained
for the following operating conditionst
