ABSTRACT:
Card 1/1
Deviating from the study of the pressure pulsation at a given
point (ref. RzhMekh 1957, Nr 1, 480), the present paper refers
to an investigation of the pressure pulsation on an isolated wall
area. The investigations were performed on a modelof the filling
conduit of a navigation lock. The construction of the model per-
mitted a certain freedom of vertical and horizontal displacement
in order to facilitate the measurement of the pressure acting on
the wall area under examination. The tests revealed that the
maximum pulsation pressures are proportional to the square of
the discharge.

'ABSTRACT:- Description of tests for the study of the hydrodynamic pre s-
sure pulsations occurring on gratings mounted at shield-type
valve gates of the filling conduits of navigation locks. The model
of the grating had a certain-freedom of displacement on its four
support points'under the action of the pulsational oscillations.
The tests revealed that the maximum impulse-of the pulsation was
proportional to the square of the discharge rate. The test results
are illustrated by graphs of the pulsations of the hydrodynamic
pressure on.the gratings plotted against the discharge rate;
the oscillograph tracings are also reproduced.

PERIODICAL% Stanki i instrument$ no. 7, 1961P 4-7
TEUs The discussed pneumatic automatic control systems have been built and
tested ai the ENIIAS pneumatics,labbrato.,,y. -The article presents a detailed
discussion of-general design principles of these systems, which are ouitable
-for use in machines, ma6hine'tbols, or,automatic transfer lines. They have
been described previously (Shcherbakovq V.I., and Yuaitskiy, S.A., "Stanki i
instrument", no. 10, 1960). A pneumatic memory unit -_ giving a command for
actuating the -work element of the machine after it has received a given num-
ber of pressure pultes - is'inciuaea into the-cohtrol system if the work ele-
ment has to function periodically after a certain number of cycles. The
interaction principle of count-ing-memory system elements is shown in a block
diagram (Fig. 1) where the channels memoriiing action pulses are marked 1

top system in (Fig. 1) is symmetric, with only one channel for each received
pulse,(both action and return), and the bottom one is asymmetric and memori-
zes action -oulses only. The "memorizing valves" are four-way air-distribu-
tion valves. Pulse amblifibirs (.Wu9-'3) in the form of three-way valves may
be used in the units for compensating pressure drop in the air lines. A
-weak pulse acts on the membrane (1), the membrane pushes the pusher (2), and
-the valve (3) opens wider and passes a high-pressure pulse trom the line.
The duct from the amplifier to the "memorizing valvell is connected to the
atmosphere when the amplifier is in the zero position. The article includes
descriptions of high-order units built up from simple counting-membry unite
meansof addition and multiplication operations, and calculations for
determining the necessary number of valves for aifferent arrangements. Two
practical examples are given - a*simple binary unit controlling the switch
of a conveyer transporting partst &nd a'unit in a storage hopper in an auto-
matic transfer machine giving'control commands after the passage of every
sixth part. There are 10 figures and 1 Soviet-bloc reference.

ABSTRACT:,' The author describes the detign of two types of sequential control Systems
for-,pneumatic drives. In its basic version such- drives consist of an air cylinder in
which the piston can assume ors of two stable positions. The displacement.of the pis-
ton is controlled by an air-distributing valve In response to external and feedback com-
mands. rigurie 1 shows the block diagram of a pneumatic prime mover (0) and the aaso-
la" ciated control'system (A). The prime mover includen logic converters (B) and a binary
delay block (0). The sequential control system (A) is.described by the equation sys-*

]where 4 and P are logic cperations, and the remainder of A
the symbols is obvious from the block diagran. It is always
assumed that the design of. the delay block (C) is given,
wbile block (B) may, or may not be specified. The perform-
ance of the control system is described by its transfer func-
A
tions,,i. e., the relation.of the output to a given input R.
With a. -fixed 'input R -the. control system is sequential- and -
Cyclic, that-is a certain sequence of outputs is repeated
in predetermined intervals. Two approaches to the desigm
of the sequential control.unit are possible: the first bas-
ed on all known required.transfer functions; the second bas-
le.d.cn auniversal command unit, incorporating a clock, and fig. 1.
capable of:generating the desiredtransfer'functions. The
structure of the latter unit is determined only by the length of the cycle. In the
-first system a filter is.incorporated wbich rejects signals from the control unit that
would cause unstable conditions. This filter may be a separate entity, or a part of
the logic unit (B). In the second system a clock determines the timing of the sequen-
tial operation.. The delays between the individual steps in the sequence can be either
fixed by-.Tbe contmi system, or'natural, due to the re5-ponse of the total system. The
advantages of the second system are in its venatility,,relfable and stable openition,
ease of uaintenance, and simplicity of synthesis. Orig. art. has: 8 figures, 7 tables.

ABSTRACT: Single-anode valves are particularly subject to extinction
of the excitation-are when grid control is used. The stability
of alternating-current excitationis reduced by the ionic current-
that flows to the excitation anode at high loads. B.A. Klyar-
felld, in his works notes the influence of the excitation anode
configuration and also of lowering the vapour-pressure on the
are stability at low loads. Other investigators have suggested
-other causes but so far extinction-of the excitation are has not
been completely prevented. Since this kind of extinction is one
of - the main def ects of -the valves j special - investigations were
conducted at the All-Union Electrotechnical Institute, with
close attention to the influence of the processes of current
commutation of the main anode on extinction of the excitation.
A sDecial equivalent circuit illustrated in Fig.1 was used to
In-yestigate the influence of commutation of the main current and
Cardl/5

The St ability of Merejary Valve Excitation Systems 110-4-13/25
reproduced the most sevemoperating conditions of the valve.
The apparatus imposes on the anode circuit of%the valve
periodically-r6peated current impulses having amplitudes of up
to 1 200 A and withrates of change.of current of the order of
107 - 108 A/see. Immediately after the current impulse has
passed, a negative voltage of the order of several kv is applied
to the,an de. The main circuit components are described. The
operation of the circuit during tests on a' large high-voltage
valve is illustrated by the oscillogram in Fig.2. The influence
of the main current circuit on the excitation system of the
valve is illustrated by theoscillogram in Fig-3, taken whilst
the excitation was working on a.e. This oscillogram shows that
are extinction occurs at the instant when the main anode ceases
to pass current. The method that is described can be used to
cause artificial extinction of the excitation are under
influence of processes in the main circuit. Hence, it can be
used to determine how changes in construction or in the circuit
influence the stability of the excitation arc.
An investigation was then made of the effect of structural
teatures of the valve on extinction of the excitation. It was

stability.. The influence of se.reening,the excitation anode
examined. As earlier work had shown that the are was more
stable if the mercury vapour pressure was raised, shields were
used to raise the pressure of mercury vapour near the anode,
but this measure had no important effect. jNor did changes in
the location of the anode relative to the-centre of the cathode
appreciably influence the stability of the excitation are.
However it was established that when the resistance in the
excitation anode circuit and the voltage-applied to the are
-were increased the-mean time of burning of the are was.extended.
It was also extended by increasing the inductance. Raising the
excitation current from 8 to 10 A greatly improved the stability
of burning.
An investigation was made of the influence of the excitat4on
current and of the amplitude of the impulse anode current on
the are stability, using an experimental mercury-are rectifier,
type PMMI 200 x 6 connected as shown in Pig.4. A constant
current was maintained in the excitation anode circuit and
current impulses were applied to the main anode. For ach value
of excitation cur-rent.-,the relationship between the time of
burning of the are-and the amplitude of the current impulse was
Card3/5 determined for two values of excitation current; the results

The Stability of Mercury Valve Excitation 6ystems 110-4-13/25
are graphed in Fig.5. This graph indicates that when the anode
current impulse ranges.from 500 to 700 A, increased excitation
causes the curves to be displaced in the direction of higher
current impulses on the main anode. In other words, the time
of burning is longer when the current is greater.
The effect of extinct-ion of the excitation are when the main
current ceases to flow (which is the main cause of unstable
operation of the excitation in single anode valves) was observed
for the first time in this work. The reasons for this are dis-
cussed in relation to the theory of Prof. L.A. Sen and the
work of A.V. Rubchinskiy. The excitation are was certainly not
extinguished every time the cathode spot disappeared. The
effect of repeated ignition of the cathode spot results from
the statistical nature of the relationship between extinction
of excitation and the discharge parameters of the main circuit.
In considering the stability of-the excitation are, it is
necessary to distinguish between the factors that reduce the
stability at low and at high loads on the main anode.
Stability of the excitation system can be increased by raising
the mean excitation current, but this is expensive. It is,
therefore, better to use other means such as a series forcing

in the excitation circuit by the forcing-transfornier and this
reduces the short-term excitation current almost to zero. When
the,main anode current falls., the excitation current increases
and reaches a peak value of almost double the main current.
When the main current has died down, the series transformer acts
as a choke in the excitation circuit so that the excitation
current slowly falls to its mean value. Forcing of the
excitation is also applicable when a.c. excitation is used.

ABSTRACT: Steel-clad mercury are rectifiers with pumps are becoming
increasingly used but are omly economic in large sizes.
A three-anode pumpless rectifier with grid control type
PM-200 which has been developed by the author in the All-
Union Electrotechnical Institute and successfully produced
in the Zaporozhe Electrical Apparatus Works affords the
possibility of controlling a drive in which the speed
varies from zero to the rated value * When dynamic braking
of the motor is used t -he grid controlled rectifier can
operate as an invertor. The main t 'echnical characteris-
tics of the rectifier are tabulated. It is int6nded for
a rectified voltage ~, of,600.N and a* current of 200 amps.
The design is described'4n some detail and illustrMted
with a sketchf. The rectifier was first tested under con-
Card ditions applying to lift drive. The tests were made on a

rectifier installation was mounted in a steel ;~;ioarzd
of 680 x 680- x 1650 nm'. Ignitiom tests were carried out
with the rectiffter both cold and hot. Load oscillograms
are given in Fig.4'. The-tests show that the voltage could
be controlled smootbly from zero to rated value both at
zero and fall load, Oscillograms taken with the grid
control in operation are shown 'in Fig'-5''Load tests and
overload tests were carried out. The rectifier type
PM,200 was also tried out in the driving circuit of a
motor in the flzvestial printing works'. Before the recti-
fier was installed in the-prinIzing woeks it was given ex-
tensive short-circuit tests in the All-Union Electrotech-
zical I=titute. The rectifier was used in the supply
circuit of one section of a rotary printing press from
August to October, 1953~'. S.L.Ettinger and F.M.Gutkin of
the Elektroprivod works developed the supply circuit.

diodes for the power supply of the asynchronous motors and conUdnlng a
converter. of three-phase voltage Into Binglem-phase, as well as a phase-splitter. ror the
purpose of ensuring flexibility in control with high efficiency and power Coefficients, the
three-phase-to-slngle-phase voltage converter (with the single-phase voltage of higher
frequency) is designed according to a 12-valve circuit with an implicitly expressed d-c
element and feeds a 12-valve phase-Bplitter. The latter consists of three single-phase
bridges with eqnalizing reactors in the diagonals, between the midpoints of'which are con-
nected the windings Of the motors. Continuous adjustment of the rate of revolution of the
motors is accomplished by employing a unit for changing the frequency of the single-phase
voltzge provided by the 3-tD-1 voltage phase converter. For step-by-step adjustment, on

of replacing. Me six IVS-50072 type sealed.nercury-are rectifiers with
Stacks of VK-200/4A type silicon rectifier cells (average curre ,at 200 ampi
operating peak inverse voltage [PIV) 400 -Y.; rated FIV-600 v) in the recti-
fier substations that, supply 825 volts d-c for subway traction. The com-
Tuted six-pbase rectifier unit ban six parallel branches per phase, with
six seriod-connected. cells por, branch, The awaber of parallel branches

ABSTRACT: Four independently pperating Geiger and scintillation counters were used
on Cosmos-17 to record charged-parcicle Ifluxes in the Earth's radiation belts at
altitudes of 260-780 km from 22 to 30 May 1963. The counters differed only in theirl
shielding and radiation detectors. Simultaneous measurements of the counting rates,
made it possible not only to determine the level of the fluxes but also to reach
certain conclusions on the.composition of the.trapped radiation and to establish the
hardness of the energy spectrum of the penetrating articles. Based on the composi-i
tion of particle* penetrating a shielding of I g/rmt, it was found that the inner
radiation belt can be divided into two resioni. At L = 1.15-1.6, the inain portion
of the fluxes is produced by electrons from nuclear explosions, at L 1.6-2d5. it

Increased since 1958. A third narrow,region was detected betwee4 the inner and
outer.radiation belts in which electrons with energies of 0.1-1~'5 Mev were recorde
Below the lower boundary of the inner belt,stable streams of soft corpuscules,
I.e-0, electrons with energies between 50 and ICYO kev, were dete ted. Orig. art.

a period of two hours, A dilatometric investigation of the -spe
cimens was conducted in the ZO-5000 ' range. The primary
factor in the stability of the gamma-phase at sub-zero tempera-
tures is the chemical composition of the alloy; in this respect
Ni appears more effective than Co. The conditions of heat
treatment and the extent of workhardening have only a slight
effect on the stability of the gamma phase. The existence of
areas with an insignificant degree of decomposition of gamma
phase in the liquation zones, is pointed out.
