ABSTRACT, An approach, based on the general theory of detection, to the problem of
the synthesis of equipment for the space-time detection of signals is presented. A
solution is found for the problem of synthesizing an optimum distributed (diversity)
signal detection system, designed to operate against the background of a random inter-
ference field. The general correlations obtained in the paper may be used when
analyzing the quality of detection of signals of finite length by two-point receiving
equipment with an infinite time base. Using this type of detection system and a
four-dimensional space-cime continuum (the direct product of infinite three-dimension-
al space and an infin-.te tima interval), the authors show that the method of space-
time signal selection makes possible a substantial improvement in the quality of
signal detection. This finding is in agreement vith previously published results

ABSTIUCTs A receiving system is considered,in which the information -about the-
transmitted signal Is derived from the field values meammed in a delimited sp6ce.'1-,-,`--
Noise sources are distributed along the t no noise sourc'e-:
ransmitter-receiver line;
is assumed in the delimited space; conventional frequency filtration of signals is'
assumed in the receiver. An integral equation of the received signal (with a limite&
dispersion of noise field intensity) is set up and transformed into a first-kind
Fredholm-type equation having a Caueby kernel. By construct;ng a sequence of linear.@
functionals with a contiTmou weight function, it is proven that the distributed
reception system-ensures an almost regular channel of communication. The near_
regularity characteristic is inherent to a wide alass of distributed.channels with
additive noise which can bedescribed by an operator with a nondegenerate kernel.

PERIODICAL: Radio, 1957, p.63 (USSR)
ABSTRACT: Tubular.ceramic bodies of KBGI condensers can be used as
forms for high-frequency coils. For that purpdse it is
necessary to unsolder both metal sidepleces from the
ceramic body,, remove all content from the tube and clean
it thoroughly. Then the sidepieces should be remotmted
on the body with one end of the winding wire fastened to
one of them. After winding the required number of turns
the other end:6f the wire should be affixed-to the second
sidepiece. The coil is then glued to the ceramic body.@
Inductance adjustment of the coil is achieved by unwind-
ing the superfluous turns.

ABSTRACT: At t0he Ural Aluminium Works, the crushing of bauxite for
producing alumina by the Bayer method is done in jaw and
cone crushers and fine grinding in wet ball mills. A
group at the works proposed the automation of the wet-
grinding department (Figure 1). Here, the crushed bauxite
has up to 5% lime added, the mixture being discharged from
the bunker by a plate feeder and conveyed to the ball mill
to wh-ich return solution and fresh alkali are added. The
pulp goes to a classifier, where return solut-ion is added,
and then to a hydrocyclone. The pulp from the hydro-
cyclone goes via mixer tanks to the leaching sector. The
objects of the automation work were to concentrate control
of the main equipment at the central control point and to
make the operation of the main units automatic under
conditions set centrally by the controller. The following
operations have been automated. The addition of return

also the distribution of the solution between mills and
classifiers and solution feed i@rom the collector tank to
the distributing device (Figuye 3). Bauxite feed to the
ball mills with the aid of a belt weigher on the feed
conveyor whose signal regulates the plate feeder via a
suitable control system (Figure 4).

feed, which is effected in the same way as for return-
solution feed. After describing the automation of the
above operations, the.authors outline the instrumentation
and the system of interlinking and overall process control
in the wet-grinding department. An alarm system indicates
the failure of a unit. The switching on and off of the
bauxite-bunker vibrators is to be automatic. The
standard electromechanical regulator made by the
"Il'marine" Works and modified for operation at a higher
pressure is used. All the equipment has been in

ABSTRACT: This article is a theoretical study of dividing Prequency by means of a,

self-ose t;*ocked in with harmonics. The analysis is conducted by
the so-called phase-pulse method, which consists in studying the phase
plane of changes in the voltage in the oscillating circuit of an
oscillator in the presence of current pulses. The author discusses the
diagram of an ordinary LC oscillator connected in the anode circuit. It
is assumed that in addition to the voltage induced by the circuit
U = Uocoscj t, an external emf e = eocos [co t i- p j (where w pz ntoo)
Aso acts on ?he grid of the tube. In order to simplify.the analysis,
the sinusoidal external emf is replaced by the corresponding sequence of
pulses with the amplitude eo. The author sets up a differential equation
describing the phase change and calculates the conditions of steady-state

It Is shown that In order to widen the division band, it is necessary to reduce the co-
efficient of division increase the transconductance of the characteristics of the plate
current of the oscillator tube, and increase the characteristic Impedance of the circuit
as well as the magnitude of the feedback coefficient. The author discusses the effect
that the amplitude and waveform of the lock-in emf, have on the magnitude of the division

out in the phase plane for the case of a small out-off angle of anode current..
The law of the error accumulation in a chain of multipliers is considered. Phase

ABSTRACT: The division of frequency is normally done by means of
relaxat.-'Lon dividers, LC-type dividers or by means of
combined r@ir,:@uits. The article deals with the theory of
an LC--type divider and that of a zombined divider. The
diagram of a simple LC divider is shown in Figure 1; ,
11-bis consists of a resonant circuit and a feed-back circuit
and compr1ses a source of the synchronising.voltage. The
amplitude and phase of 'he system are governed by the
foJilowing simplified equations:

n times smaller than the frequency of the external electro-

These equatioas can be used to analyse the LC divider shown
in Figure "-/:. In this, the righthand-side tube converts a
sinussidal voltage into re-,tangular phase-inverted pulses

re-tang-alar pulses; this is also fed to the grid of the
ieithand--3-ide tube. Consequently, the tube is conducting
when bcth the voltages at the grid are equal to zero and
it is closed when one of the voltages is negative. The
envelge of the anode current pulses can be expressed by
Eq (it"), where i. is expressed by Eq (18), where Ri is
the internal resistance of the lefthand-side tube. The
parameters JCa and J. 0 ian, therefore, be written
in the form of Eqs (19) and (20). The steady-state
amplitule U . and steady-state phase shift (pCT can
be w-ritten as Bqs (28) and (29). The synchronisation

If -14-he synrhronising pulses are in the form of a sinusoidal
signal, the parameters J0m and J.0 are expressed by
Eqs (:8) and (39), respectively; in this case, it is found
that 'rhe eyne.'IlirorrLisation bandwidth is about W6 lower than
in the presence of rectangular synchronising pulses. Large
,%7r,cb-'ronising bandwidths can be obtained if a combined

TEXT: The phase-shift frequency meter is based on the use of
a four-pole with linear phase characteristic in the operating
range of frequencies, and the measurement of the phase-shift of the
unknown signal after passage through the four-pole. The authors'
previous work (Ref.l: A.I. Danilenko, Radiotekhnikag 1957, Vol.12,

three basic sources of error: instability of the four-pole
frequency-phase characteristic; instability of the group delay of
the four-pole; phase meter error. Departure from nonlinearity of
the four-pole characteristics is neglected in this analysis since
it can be taken into account in the initial calibration.
Assuming independence of the three sources of error they can be
added in quadrature. A qualitative idea of the error behaviour is

which parameters of specific four-poles can be substituted.
Examples are given for phase meters using single-tuned and double-
tuned resonant filters as the phase-Sihift network.

ABSTRACT: A further development of the phase-pulse method applicablet to
systems with arbitrary active and reactive nonlinearities., where oscillations
differ greatiy from the sinusoidal, is reported. The essence of the method was
reported in earlier articles by this author (Radiotekhnika, 1959, 4, no. 1, 43,
and 1958, 1, no. 3, 362). The case of an oscillatory circuit with a nonlinear

ABSTRACT: The problem of frequency division by 2 by means of a nonlinear capacitance
is considered. Excitation conditions and resonance curves with and without an
inertial nonlinear negative resistance are determined from differential equations
and a phase portrait. WIth ratios 3, 4 and higher, the reciprocal nonlinear capaci-
tance is approximated by a trinomi.al. The second and third harmonies of current are
taken into account. The cases with and without periodic solutions and their
stability are considered. A study of the phase-plane topology shows that, with a
certain amplitude of the external force., a stable singular point exists and,
therefore, the division is possible. However, initial conditi6ns are necessary
which would keep the operation near the singular point. Thus,.with a sufficient
amplitude of synchronizing curiefit'And with'a sufficient capacitance nonlinearity,
a hard excitation results; the system should be somehow excited in order to perform

division. On an oscillation collapse, the division is not restored by itself.
Stable division can be obtained by connecting an inertial negative resistance
(tunnel diode, dynatron oscillator, etc.) to the circuit. In this case, the
division band is widened. The nature of oscillation limiting plays an important
part in the above phenomena. Experimental studies with a dynatron.osciUator
corroborated some theoretical claims, specificaIlys the presence of hysteresis
in the system. With the negative resistance'# the division by 3, 4,-and 5 was observed.
Without the negative resistance, only division by 2 was observed. With certain
external-current amplitudes, the division by 3 persisted also without the nega@ive
resistance, but did not reestablish itself on oscillation collapm Eleven figureV*
