YRRIODICAL: Vestnik mashinostroyeniyas no. 3, 1962, 45 -.48
TEXT: A new method of force fitting by means of deep freezing of
assembly details, is described. Basically the method consists in
cooling a part in liquid nitrogen before assembling. Several experi-
ments carried out by the author are described in detail. There were
fitting of bronze and long steel bushes) and fitting of small and
iarL-,e cast iron pinions..This method considerably reduces -the Dro-
duction costs, increases operating efficiency and eliminates hard
.manual work. Apart from that,-strength of coupling is increased, de-
formation of details reduoed, and general quality of assembly im-
-proved. There are 7 figures and 1 table.

TEXT: In order to obtain the comparative values for the strength
of deeD-freeze fits a number of tests was made with the experimental
sets e~cl~ consis'ting of a plug and a ring: 1) Assembled with'the
aid of hydraul'ic press, lubricated, 2'~ assembled, without protective
coating, with cooling ii. liquid nitrogen at - 1960C, 3) assembled
with cooling in liquid nitrogen at - 1960C with protective coating
of the ring fitting surface: a) nickelp b) zinc. The results of the
tests, showing the changes in the pressing-out efforts at various
relative positions of the plug and the ring for different methods of
assemblingy were recorded in form of tables and graphs, analyzed and
the following conclusions reached: The strength of the deep-freeze
fits with-Drotective electroplating is much higher than the strength
of ordinary press fits, and the contacting surf a(~677wemain clean and

ABSTRACT: Stationary measuring servo systems, used for dete;rmining
coordinates and parameters of moving objects, generate an estimator that
approaches the input function. , To improve the approaching process, the use of a'i
digital computer in the predictive measuring system is suggested. Syntheolzing
mean-square -error -optimized predictive measuring systems containing a digital
computer is considered. It is fountl ihat the inclusion of digital computers may
substantially improve the smoothness' of the measuring system. As compared to'i

TITLE: The effeot of initial pressure on static characteris-
tics of electio-hydraulio drive
PERIODICAL: Izvestiya vysshikh uchebnykh zavedeniy. Mashino-
stroyeniyet no. 9# 1960t 95 - lo3
TEXT: The electro-hydraulic drive is a power amplifier without
feedback. However, the relationship between the input of servome-
chanism and the load forms an.equivalence to a negative feedback.
The unit (Fig. 1) consists of a two-chamber gear pump 1, electric
motor 2p control by a polarized relay 31 and valve and working memX
ber - Bervomot6r 4. The piston of the latter is actuated by the
difference in pressure determined by the position of valve spools
10 and llp controlled by relay tie rod 15 and the rocker. The pro-
portionality between the input signals of the polarized relay and
the position of its armature is ensured by spring 20. 'When no con-
trol signal is present, opposite currents flow in the coils of the

relay, and the armature will.occupy a middle position, with spools
opening equal orificesp and thus no drop of pressure is produced.
The author quotes analytical work for calculating the static cha-
racteristics of the drive, where he ties the displacement of spool
h, with the speed of its travel. The torque is given by

where Re is the radius of the,crankl P is the piston areav and a Vi/
is a parameter which takes into consideration the load effect on
pump delivery. In the case of small displacements h, the torque
characterietic is lineart whereas in the working range this is
achieved b3r an increase of the initial pressure, p or the cross
section of piston F. The latter arrangement reduceS the speed of
power of piston. The static speed characteristic is then conside-
riad. Its slope is proportional to the output of pump and inversely
proportional to the cross section of the piston. An equation is
deduced for spool displacement at the start of motion h. , in rela-

tion to tho initial and starting pressures. In order to determine
the effect of the initial pressure, experiments were carried out
whose results are plotted. These allow the following conclusions to
be made. The speed of the output ahaft u) as a function of the sig-
nal current is independent of the initial pressure. The maximum
speed corresponds to full closure of valve orifice connected with
working-chamber of cylinder, and completely open exhaust. The star-
ting current decreases with the rise of po. The speed of return
stroke drops when initial pressure goes up, The slope of speed cha-
racteristic is constant for all load torques. The increase of p0
causes a straightening of the torque characteristic, whose slope
is maximum at p0 = 0. This curve exhibits saturation for certain VA"',
values of signal current. There are 8 figures.

TITLE: Broad-Band Amplifiers With Distributed Amplification
(Shirokopolosnyye polosovyye usiliteli s raspredelbnnym
usileniyem).
PERIODICAL: Radiotekhnika, 1957, Vol. 12, Nr 12, pp. 73-80 (USSR)
ABSTRACT: The character of the frequency characteristics of amplifiers
with distributed amplification (ADA) are essentially determined
by the type of artificial lines used. It is therefore possible,
if the artificial lines are composed of band filters, to
obtain an ADA. The amplification coefficient of the ADA

the slope of characteristics, and the input voltage of the
anode line C - 'n S Zinput' It in shown that the frequency
characteristic is a curve with 2 humps. In principle it is
possible to produce band ADA by means of artificial lines
from any band filters which are connructed with one another
according to the adaptation principle. From the point of view
of construction the artificial lines must be extremely
simple. The best success will be obtained with artificial

Broad-Band Amplifiers With Distributed Amplification 108-12-10/10
which are special cases of a band filter of the type M
with 6 elements and 2 coefficients. The method of
calculating such amplifiers is described. Next, schemes of
ADA with triodes are shown. The scheme with "Cascade with
cathode load - cascade with earthed grid" is very stable in
operation as the anode- and the cathode circuits are nearly
perfectly separated from each other. It is very useful to use
double triodes. At the end, experimental results are dealt
with. An experimentally recorded frequency characteristic is
shown. A phase characteristic was not recorded.

voltage whose amplitude is proportional to the input voltage, with subsequent regu~-
lated amplification and synchronous'detection. The difference between this axpli-
fier and those now in general use is the uti3isation of the storage principle in the
input circuit, thus causing a sharp increase in resistance to high-frequency inter-
ference. The equivalent circuit of the amplifier can be in the form of two separate
integrating circuits -- input and output., having practically identical time con-
stants. Fig. 2 is a circuit diagram of an amplifier employing the storage affect in
the input circuit. The process of signal conversion is %treated mathematical]4- in con-
siderable detail; an expression is derived for use in determining the width of the
passband for such an amplifier. There are 5 figures.

by a magnetic current ring, of a metal cylinder of infinit6 length
coated with a dielectric layer. It is shown that this gives rise
to a surface plane wave propagated along the cylinder, and to a
spherical radiation wave. The excitation efficiency of a plane wave
is determined (energy ratio between surface and space waves). The
radiation resistance of the system is deduced. This problem is
closely connected with papers on excitation of a metal cylinder and

TFM-. The problem of lumped excitation of an infinite
impedance plane by a magnetic current filament is considered.
The plane has an Isotropic Impedance and-represents the simplest
delay system. The impedance plane, whose surface coincides
with the coordinate plane y, z (see Fig. 11, is excited by an
infinitely long magnetic current filament j , which is
parallel to the axis y , which is situated at a distance x
0
from the impedance plane; thus:
im = 3:mb(x - x0 )OW

where x m x. and z 0 are the coordinates of the source, and
IM is the amplitude of the source.
Under these excitation conditions only the three field components
are produced, namely - 1%C' RZ and H y . The component H y
can be found by solving the Maxwell equations, while the other
field components can be exprAssed in terms of H The
boundary condition at the impedance surface is:
RZ = Z Hy/x=o
where Z is the surface impedance. It is shown that the
surface-wave component of the magnetic field is given by:

concluded that a plane electromagnetic wave impinging on an

On'the other hand, -when the surface waves are excited by a
lumped.source, the efficiency of exzitation depends on the
delay coefficient h /k and the distafice of the source
