ABSTRACT: This Author Certificate presents an apparatus for controlling the thick-
ness of a metallized coating (such as that on a condenser paper) according to the
magnitude of its ohmic resistance. The apparatus contains a contacting mechanism
connected to the measuring block. To automate the controlling of the metallic coat-
ing thickness on the condenser paper in the course of cutting such paper, the con-
tacting mechanism is made in the form of two rollers between which the paper is
pulled. The measuring block is connected through a timing device to a cutoff mech-
anism (see Fig. 1). An air auction arrangement, placed between the contacting mech-
anism and the cutoff mechanism,, serves to remove the cull portions of the condenser

TITLE: Special-purpose lathes made by the Ryazanskiy stankostroitellnyy
zavod (Ryazan' Machine-Tool Plant)
ftRIODICAL: Byulletent tekhniko-ekonomicheskoy informatsii, no. 4, 1961, 27 - 31
TEXT: . . The author gives a description of four new special-purpose lathes
manufactured and designed at the Ryazan' Machine-Tool Plant. .. 1) PT -74C M -74S)
screw-cutting lathe is intended for the machining of large-size parts of ferrous
and non-ferroua metals. The bed-consists of three sections reinforced by -shaped
ribs which ensures a high rigidity of the bed structure. The bed has three pris-
mati o bedways. The carriage travels on the front and rear bedways while the tail
stock is displaced on the center bedway. The spindle is driven by-an electromotor
via a V-belt drive. The high-speed gears are ground while the others are shaved.
The apron is fitted with four bleatromagnatic clutoheq. Owing to a free-whe
clutch mounted in the apron housing the rapid motion can be switched on during
the working feed. The gear case is of the closed type. To cut high-precision
thread the lead screw can be coupled directly to the receiving shaft of the gear

case by a clutch. The lathe is fitted with seven steadies. A flanged electric
pump of 45 I/min capacity iv intended for the coolant supply to the cutting tools,
The possibility of high-speid machining considerably increases the efficiency of
the RT-74s lathe. 2) Pr -1:0 (RT-130) special purpose copying lathe for the
finish machining of compressor parts. The lathe Is also fitted with a mechanical
carriage for rough machining. The bed, head stock, gear case and other parts do
not.differ in their design from.the corresponding parts of the RT-743 lathe. The
hydraulic copying slide for the finish machining of parts can travel in the longi-
tudinal direction together with the carriage, and in the transverse direction to-
gether with the cross slides on the carriage bedways; besides It can be displac,:?d
at an angle of 600 to the lathe center axis on the bedways of the swivel carriage.
The swivel part on the carriage cross slides can be turmed through any angle and
clamped in any required position. All bedways of the hydraulic carriage are of
dovetail shape. 3) PT -136 (RT-136) special-purpose copying lathe Is intended
for the machining of shafts, stepped shafts, and various complex shapes and coni-
cal surfaces. The lathe is fitted with a four-position templet rule of the copy-
ing carriage. The lathe Is set on the required dimensions by the first part. The
accurate setting and fixing of the templet rule ensures the machining accuracy be-
ing maintained for all following operations, taking into accolzit also the tool

wear. 4)PT -146 (Hr-146),opecial-purpose lathe Is an automatic for the machining
of automobile rear axle crankcase flanges. The automatic cycle Includes: clamp-
ing of parts, tool advance, machining of parts simultaneously by four slides, re-
turn of tools to the initial position, and unclamping of parts. The reducer for
the automatic spindle displacement Is positioned on the rear face end of the head
stock in such a way that the loadIng and unloading of parts can be effected In a
convenient manner. The lathe has two carriages mounted on the bed, and fittpd
with two hydraulic slides each.(longitudinal and transverse). The tail stock Is
hydraulically operated. The front part of the tail spindle carries a devi,~e fcr
the gripping and centering of the component mandrel. If the pressure in the h-y-
draulic tightening system of the tail stock spindle drops or fails the lathe
stops automatically. The*parameters of the automatic cycle are set by electric
terminal switches and catches. A control panel is mounted on each carriage which
considerably facilitates the setting of the lathe. While a Bacon (Bekon) lathe
takes 18 minutes to machine these parts the new FT-146 lathe needs only 2.5 - 3
minutes. The table shows the t ,echnical data of the four lathes described. There
are 3 figures and I table.

Abstract By means of a graphical investigation of amplification region of a
traveling wave tube and a double-beam cathode-ray tube over a wide
range of parameters it is demonstrated that for low frequencies and
high currents in the traveling wave tube there is a new solution
stipulated by the interaction of waves or the field and the space
charge traveling in the negative direction. Graphs of phase velo-
city relationships under different conditions are given. The
graphical method used allows investigation of algebraic dispersion

ABSTRACT: The conference took place during September 23 - 29, 1957,
at Saratovqkiy gosudarstvennyy universitet imeni
N.G. Chernyshevskogo (Saratov State University imeni
N.G. Chernyshevskiy). Apart from the universities, the
conference was attended by the representatives of some
scientific research institutes of the Soviet and
Ukrainian Academies of Science, various industrial
establishments and the interested ministries. This
arrangement stimulated the discussion and evaluation of
the papers presented and permitted the determinatiom of
plans for the future research to be carried out by the
universities in the field of radioelectronies.
In view of a large number of papers and communications
(over 15;0), the majority of these were read in various
sections (electrodynamic8, electronics, radiowave

conductors and their application in radio equipment).
During the plenary session on September 23, two papers
wDre read: "Development Trends of W7,Zlectronics ia tne
Boviet Unioh" by N.D. Devyatkov and "Electromagnetic
Waves in the System of Vari-directional Electron Beams"
by V.M. Lopukhin. N.D. Devyatkov presented numerous-
factual data illustrating the rapid development of the
U.H.F. electronics in the Soviet Union and the vast
contribution of the Soviet scientists to the theoretical
foumdations of this science; he also discussed the
development trends of U.H.F. electronics in the immediate
future. The paper described a number of original Soviet
U.H.F. devices. The work of V.M. Lopukhin was concerned
with the theoretical investigation of the phenomena taking
place in multi-ray devices whose electron beams have
different directions. The author showed that the presence
of the electron beam which are perpendicular to the axis
x facilitates the appearancQ of the solutions which are

appearance of exponentially increasing solutions in the
presence of one beam in the above direction. The Electronics
Section comprised 50 papers; more than one-third of these
wex,e concerned with the theoretical and experimental inveBti-
gation of wide-band electronic davices for U.H.F. The
lecture by V.N. Shevchik, L.Ya. Mayofis and L.D.Pokrovskiy
dealt with the extension of the known theories of travelling-
wave tubes and backward-wave tubes to the practically
import-ant cases when the delay structure necessitated the
taking into account of the discrete character of the
interaction of the electron beam with the high-frequency
field. The lecture by V.C. Stallmakhov, V.N. Shevchik
and Yu.D. Zharkov was devoted to the simplified analysis
of the operation of a backward-wave tube by employing the
cosinnsoidal approximattion of the given field. The papers
by V.B. Braginskiy, A.S. Gorshkov, A.I. Kostiyenko,
G.P. Lyabimov, I.T. Trofimenko and V.V. Anisimov were
concerned with the detailed experimental and theoretical
investigation of the Dossibility (first indicated by
V.N. Shevchik in 1954) of expanding the bandwidth of

operation of reflex klystrons with multi-circuit resonant
systems was also investigated. The results of experimental
and theoretical investigation of two-ray amplifying and
multiplying tubes were given in the communication by
L.Z. Aitova, V.M. Lopuk-hin L.A. Shkudova and in the
communication'~-o~_. ~.a~Evets. Some of the papers in the
Blectronies Section dealt with the investigations which
were concerned with the development of novel U.H.F. devices,
suitable for the generation and amplification of the wave-
forms in the millimetre and sub-millimetre ranges. The
papers of great interest were: "Experimental Investigations

the thermal fluctuations at the signal source (related to
the origin of the interaction space). Vie tube is illustrat-

electron gun, 2) an input resonator, 3) an output resonator,
4) a collector, and 5) the interaction space. Evaluation of
E. and Eit is carried out under the assumption that the
charge density in both the beams is identical and that the
amplification takes place past the modulating grids. It is
further assumed (Ref.2) that the alternating components of
the velocity and the current density in the beams can be
written in the forms of Eqs.(2), where k is the beam wave
number, n is the number of the beam (n = 1 or 2) , e/m

amplitude of the kth wave, w is the angular frequency,

ABSTRACT: The aim of the present note Is to study electromagnetic
waves in a system of electron currents having different
directions. A solution of one of the special cases of
this problem was given earlier in the work of J.R. Pierce
and L.R. Walker (Ref 1). In the present note the problem
is solved with the aid of a more general method based on
the simultaneous solution of the linearized kinetic

quation which are given by Eqs (1) and (2), where
e and m are the electronic charge and mass, respectively.

TZXTs The object of this article is to obtain the characteristic
equation (for V ) for & stream of electrons, velocity and current-
density modulated at a frequency w , further velocity and
current-density modulated at the double-frequency 2w, taking
into account the electron-velocity spread7. It is assumed that
the modulation at the double frequency is large compared to the
signal-frequoncy modulation. The roots of the dispersion
equation are obtained'on the assumption of Poisson distribution of
electron-velocities. The initial starting equations are the
equations of motion obtained by Louisell and Quate (Ref.2)

TITLE: The Linear Theory of Double-Beam 6ackward-Wave Tube
and Travelling-Wave Tube Amplifiers
PERIODICAL: Radiotelchnika i elektronika, 1960, Vol-5, No.11,
pp.1837-1847
TEXT: A theoretical investigation of the double-beam travelling-
wave tube and backward-wave tube is given. In these tubes the
interaction of the beams on each other is superimposed on their
interaction with the delay line. The tubes thus represent a
combination of an electron-wave tube and a travelling-wave tube
and an electron-wave tube and a bacl.:ward-wave tube respectively.
Since the bunching mechanism in the t.w.t. and electron-wave tube
is similar, when the average velocities of the beams are
sufficiently close the second beam would be expected to introduce
travelling-wave interaction. In the limiting case of equal beam
velocities, a t.w.t results. With increase in the difference in
the beam velocities the bunching mechanism begins to differ from
that in the backward-wave tube and the amplification ducreases.
In the d ble beam backward-wave tube the situation is more complex

since the beams and energy travel in opposite directions and the
bunching mechanism in the backward-wave and electron-wave tube are
different. For small electron densities, the electron wave
interaction might possibly be small and the process may simply be
a superposition of backward wave interactions. In deriving the
dispersion equations the notation in Pierce's book is adhered to.
Assuming the conditions of small signal theory and using the
result of Johnson's paper Otef.4) for a double-beam backward wave
tube the propagation constant r will satisfy the dispersion

where-the symbols have their usual meaning, The roots of the
two dispersion equations were calculated on a computer considering
amplification conditions only and not oscillation. Investigation
of the roots of Eq.(8) and (13) enables the following conclusions
to be drawn. In both tubes there are five waves, one having
constant amplitude. The others may have constant amplitude or
may be amplified or attenuated within certain limits depending on
the parameters. The phase velocitit-s of two of these waves are
close to the average velocity of one beam and the phase velocities
of the other two are close to that of the second beam. In the
degenerate case (a = I or C2 = 0) there are three waves, one of
constant amplitude and two increasing or attenuated waves trith
velocities close to that of the first beam. The roots Ok in
this case agree with those obtained for the ordinary backward wave
tube. The increase or decrease of the waves is determined by the
corresponding root Re6k since the amplification factor is
proportional to ClNRebk- The beams also affect each other very

strongly when their average velocities differ slightly, but in this
case an ordinary t.w.t. or b.w.t. is obtained, The relation of
the roots to the different tube parameters is shown in Fig.2 for the
b.w.t. and in Fig.3 and 4 for the t.w.t. Expressions for the field

on the parameter Cl, C2, a and QCI. For certain values 25 dB
