TITLE: Device for the Control 6f Deep Holes in Internal Grinding
PERIODICAL: Stanki i Instrument, 1960, No. 12, pp. 216-28
TEXT: The authors describe a device for automatic control of deep holes
270 - 290 mm in diameter and up to 1,400 mm deep during grinding in cylinder-type
parts. The device is to be fitted to the model A'W-83 (KhSh-8.3) internal grinding
machine and consists of split collar-type clarnp 2, fistened on the spindle of the
grinding stock,- a rocket joined with the clamp, pneumatic cylinder 3, damping
spring 4 and interchangeable measuring heads 1. The main unit of the device is
the three-contact head for measuring the h6le diameter. The devicelis equipped
with four interchangeable measuring heads, each of which fitted with a AW-15
(DI-15) induction pickup. The measuring heads are set beforehand on the*fixed
diameter of the hole being checked with the aid of two gaging rings, which deter-
mine the graduation and setting of the device. The measuring heads differ from
each other only by their measuring endpieces, the length of which is determined
as the difference in radius between the hole being measured and the standard

ABSTRACT: Comparative analysis of the materials obtained from the
electro-prospecting carried out in the Central Ural
resultea in some important -:conclusions. One of them is
that owing to the varying thIckness of deposits, the
compensation method cannot -Practically define a uniform
field. The complex character of the field obtained did
not allow tracing the origin of the irregularities in the
ore distribution, even in the shallow deposits in such
localities as Yurlyev Slonov, Shaytan. Alsodue to the
complexity of the fieid it vras difficult to establish the
right spread of the cabie, therefore', often some parts

observed that the various factors, other than those for
the ores, were alfecting the measurements carried out by
the compensation method, over the metamorphic rocks and
slates. In addition, due to the small distance between
the electrodes, it was difficult to determine the area
of increasing or decreasing e-lectro-conductivity, even
for shallow layers of less than 50 m. Therefore, if an
indirect relation between the ore layers to the shallow
deposits is required,, the method of compensation and
its varition,the method of vertical field, cannot be
employed even if the irregularities of conductivity are
checked by means of the isolines (Figs.1 and 2) through
holes drilled deep into the ore layers (Pianko-Lomov
and Teplov), In the case of the disturbed field where
the layers of metamorphic rocks and slates aff-act the
electro-oonductivity, it is impossible to determine the
irregularities of small intensity (range of 10016) related
to the ore layers below 50-100 m. It can be said then
that the limitations o' f the compensation method in search-

ABSTRACT: The mixed phosphor-6-molybdenum-6-tungE;ten heteropoly acid
was investigated. The roentgenograms of' the non-mixed and the
mixed heteropoly acid were compared and it was found that the
intensity of the lines of the mixed heteropoly acid is weaker
than that of the liaes of the non-mixed acid. The structure
of the anions in the mixed heteropoly acid is analogous to
I n-
the structure of the anions of the non-mixed acid. The '.
tensity of the lines of the mixed heteropoly acid found by
calculation corresponds to that found by experiments. The
geometrical position of the atoms of molybdenum and tungsten

ABSTRACT: The authors consider the effect which the anisotropic deformational and
strength properties of fiberglass-reinforced plastics have on the strength and rigidit)
of components made from these materials, and also study effectiye methods for control-
ling the anisotropy of this type of plastic during the stq~~process. The effect
of mold design on filler orientation is discussed. Fiber orientation may be selected
to suit the conditions under which the component is designed to operate. It is shown
that the structural anisotropy of fiberglass-reinforced plastic may be used to advan-
tage in making components from this material when the system of external forces acting
on the component is known. The nature of the initial material must be taken into con-
sideration together with the method used for preparation of this material and-the
stamping conditions in order to select optimum fiber orientation. An example is given

action of alcoholate in a practically anhydrous medium, but
that it is subjected to that of phenolate in aqueous alkali

ABSTRACT: The substitution of the aromatically bound halogen atom by
other substituents encounters much more difficulties than
similar reactions in the aliphatic series. Only the activating
influence from behalf of the electrophile substituent as well
as the catalytic effect of copper and its compounds make it
possible to carry out the substitution reactions at temper-
atures below 2000. With re-ard to -the theoretical importance

the preparative possibilities of the reactions mentioned in

of the azo dyes formed were of interest to the aiithors,
especially since this problem has been touched only in patent
literature hitberto. 2-chlorobenzeneazo-21-n--phthene, i.e.,
the azo dye of 2-chloroaniline and 2-naphthene was used as
initial substance. The substitution of the chlorine atom by
the alkoxy groups with the methyl-, ethyl-, n-butyl-, isoamyl-,
n-hexyl, n-octyl- and n-octadecyl radicals was obtained by the
conversion of the sodium alcoholates with this dye. It was
shown that the substitution in the given o-haloGen-ol-oxyazo
dye in the presence of copper salt takes place on mild con-
ditions. Some of the synthesized dyes may be used in the dyeing
of acetate- and polyamide fibers accordinE to the suspension
method. There are 17 references, 11 of which are Soviet.

PERIODICAL: Radio, 19619 No. 3, pp. 21 - 24
TEXT*. The normal amplifiers based on electron tubes or
semiconductor devices are not particularly suitable for the
detection of very weak signals due to the comparatively great
internal noise. In recent years, this disadvantage has been
partially overcome by the use of so-called parametric ampli-
fiers. These are in the form of oscillatory systems in which
one or some reactive elements (L or C) change periodically
with time. In general, it is comparatively simple to change
periodically or modulate the apacitance C of such a system,
The energy from the source; known as the pumping source,
which modulates the capacitance is converted intothe signal
energy by the reactive element. Such an amplifierconsisting

of an oscillatory circuit with a variable parameter and a
pumping source, behaves. in fact, as if the pumping source
introduces a negative resistance -z- into the signal
circuit. This resistance reduces t-jile ohmic losses in the
circuit and increases its quality factor Q . However, apart
from supplying a sufficient oscillation amplitude for modu-
lating the capacitance, it is also necessary to secure the
coincidence of the phases of the pumping and signal sources;
further, the pumping frequency should be twice the signal
frequency. A semiconductor diode whose capacitance is
dependent on voltage can be used as the modulating reactance
for a parametric amplifier, The magnitude of the negative
resistance introduced into the circuit by such a diode is
determined by -r = +m/2wC , where C is the average value
of the capacitance, w is the signal frequen--y and m is
the modulation coefficient which i-4 defined by

From these formulae it is seen that the negative resistance

semiconductor diode can be represented by a variable capaci-

operating up to 50 MC/S , Cv = 10-15 PF ~nd Rs = 15 - 20 ohm;
with the diodes opwating up to 500 Mc/s , the capacitances

possible to employ the capacitance of the collector-base
junctior in transistors as the reactive element in parametric
amplifiers since its akpacitance is voltage-dependent.

From the available technical literature,, it in known that the
effective noise figure for a receiver provided with a semi-
conductor parametric amplifier is of the order of 0.3 to I
(from -5 to 0 db). Thus, for a bandwidth of 1010 kc/s and
an input resistance of 75 ohm it is possible to receive signals
whose magnitude is about 0.2 to 0.3 '~LV. However, the reduction
in the noise of the input stage can result in the increase
of the overall sensitivity of a receiver only in that case when
the input stage has a sufficiently high gain. In practice,
this gain should be of the order of 15 - 20 db and this can
easily be realised. There are 6 figures and I table,

TITLE: Parametric Amplifiers. Principal Types of a
Parametric Amplifier (PA) Based on Semiconductor
Diodes
PERIODICAL: Radio, 1961, No. 5, pp. 17 - 20 and 25
TEXT: Parametric amplifiers based on semiconductor diodes
can be divided into three basic groups: single-circuit
regenerative PA; double-circuit PA (regenerative, non-
regenerative amplifier-converters and regenerative amplifier-
converters) and non-regenerative travelling-wave amplifiers.
The operation of these devices and their characteristics are
discussed in some detail. The basic.c1rcuit of a single
tuned amplifier (taken from available literature) is given
in Fig. la. The regenerative amplification in this circuit
is achieved by varying the capacitance C v periodically at
the pump-frequency f H ' which is twice as high as the signal

frequency f. 0 The circuit shown operates at fc = 30 Mc/s,
the input signal being applied to the terminals 1 - 3. The
output signal is taken from the terminals 2 - 3 and the pump
signal is injected into the terminals 4 - 5. The coil LI of
the amplifier contains 12 turns wound on a former of 16 mm
diameter. The nonlinear capacitor C . can be in the form
of a semiconductor diode or varicap (CO = 15 - 40 pF);
alternatively, the collector-base junction of a transistor such as
11-LO-3 (P-4D3)can be used'for this purpose-, this is shown in
Fig. Iro. The negative bias voltage of -5 V is applied to
the nonlinear capacitor by means of the resistor R I
from the potentiometer R2 * The pump signal is fed through
the capacitor C 'and the choke)from the coil L. , which is

wound together with L 3 on the same ferrite core. When
operating under regenerative conditions, the amplifier of

Fig. la can give a stable gain up to 30 db. Alternatively,
the system can be operated as a super-regenerator, in which
ease the pump source is modulated by an auxiliary signal.
In this case, the amplification can reach 50 db. Two-circuit
parametric amplifiers consist of two tuned circuits coupled
by means of the nonlinear capacitance, which changes at
frequency f H under the influence of the pump signal. One of
the circuits is tuned to the signal frequency f c , while the
second (auxiliary) circuit is tuned to the difference
(f H - fc) or sum (fH + fc) frequency. These frequencies
are produced as a result of the interaction of the pump and
signal voltages at the nonlinear element in the same manner as
in the ordinary frequency changen There are three types of
double-circuit parametric amplifiers; these are shown in
Figso 3a One of the main advantages of the double-tuned PA
is the possibility of using the pump frequency which is "t
exactly twice the signal frequency. Secondly, the deviations
of the pump frequency and the deviations between the signal

and pump phases do not affect the operation of the amplifier.
The first circuit of Fig.3 is a regenerative PA. The signal
to the nonlinear capacitor Cv is applied from the tuned
circuit L IC, , the pump voltage being applied directly to the
capacitor. The difference frequency signal is produced in the
second tuned circuit L 2C2 - A practical. amplifier circuit,
operating at-144 Mc/s is described; this is taken from the
American journal IIQST" of August, 1959. The second circuit
of Fig. 3 is a nonregenerative amplifier--converter, which is
essentially similar to the first amplifier, except that its
auxiliary circuit is tuned to the frequency f = f H + fc
The last circuit of Fig- 3 is a regenerative parametric
amplifier-converter and it differs from the non-regenerative
amplifier in that its auxiliary circuit is tuned to the
difference frequency. However, this amplifier is based on
two effects,- the regenerative effect due to the fact that the
auxiliary circuit is tuned to the difference frequency and

the non-regenerative amplification effect produced as a
result of frequency-changing in the nonlinear reactance
element since the load is connected to the auxiliary tuned
circuit. The travelling wave PA'akb usually in the " '
form of a section of a long line with a number of parametric e
d1odes; a syst-am of this type is shown in Fig. 9.- It is
pointed out that the special measures adopted in some k to
reduce noise are not considered and that it is possible to
construct PA on the basis of forromagnetic or cathode-ray
elements. It is also mentioned that the.parametric ampli-
fication effect was'discovered by the school of the Soviet
scientists L.A. Mandellshtam and N.D. Papaleksi, who investi-
gated this phenomenon between 1920 and 1940. A large
contribution to the investigation of PA,is due to thi following
Soviet scientists: Rytov., Tychinskiy, Etkin, Skvortsova,
Gertsenshteyn and others, whoso work was published In the'
journals: Radiotekhnika, Radiotekhnika i elektronika and

ABSTRACT: When movements of the earth's surface occur because of
underground workings, a trough is formed. The dis-
placements are differentiated by the author into central
and m~Arginal. A. solution of the problem concerning
distribution of displacements and stresses at the
boundary of a 3emi-plane having a groove in it in the
form of a horizontal slit, based on the theory of
elasticity for isotropic media, gives a qualitative

affected by mining operations. From the derived formulas for the
horizontal ani vertical components oP movement and for tiie stresses,
it follows that 1) the value of the elastic displaceme nt of points
on the surface depends on the physical and mechanical properties of
the roof rocks, and Is inversely proportionb.1 to the sheLir modulus
for the given rock; 2) the amount of displacement is directly
proportional to the square of half the widtL of the workings; 3)
the amount of displ,cement does not depend an the depth of the
workings; 4) the length of the margin of the trough Is directly
proportional to the depth of the workings; b) from the independence
of amount of displacement of surface points on depth and from the
dependence of the margin of the trough on depth, it follows that
a decrease in angle of displacement with increase In depth is
determined by the critical settling of the points, and Ln increase
in the angle of displacement is determined by the critical values of
slope and change of slope on the curves of settling; 6) the slope of
the curve of settling changes in inverse proportion to the depth,
but the cha e in slope is inversely proportional to tLe square of
the depth; 7~ a relationship is recognized between the vertical and

zontal displacement,'rl is the a0unt of vertical displacement, x is
the depth to a given layer of rock, and H is the depth to the
workings; 8) the curve of vertical displacement hLs an inflexion
(discontinuity) at x = 0.474 H; 9) the curve of horizontal dis-
placement has a maxImum. at x = 0.578 H, which corresponds with the
point of change of sign in The stresses; 10) the ratio of maximum
horizontal displacement to vertical is equal to 0.32; 11) the value
of the stresses, forming at the surface during development of the
trough, is directly proportional to the specific gravity of the
rocks and to the square of half the width of the workings and
in.versely proportional to the depth of the workings, 12) a relation-
ship is established between the stresses and the horizontal dis-
placements; 13) the amount of displacements of points on the surface,
determined by elastic theory in the marginal part of the trough, is
less than the actual, but the difference in most cases is not large.

TITLE.- Parametric amplifier
PERIODICAL: Radio, no. 11 1962, 47-49
TEXT: The authors describe the construction-of a parametric
amplifier which is to be conn-ected to the input circuit of a
television receiver as a means of increasing the signal to
noise ratio for long-distance reception. An approximate ampli-
fication of 8 to 10 dB is claimed over a 1.7 to 2.0 Mc/s band-
width clear images on 300 to 350 lines and clear sound signals,
The circuit is recommended to experienced amateurs despite its
simplicity. This parametric amplifier un-ft consists of the am-
plifier proper and its pumping signal generator which can be
any sine wave generator working in the 200 to 250 Mc/s range
with a smooth output power from 1 to 100 mv. Two alternative

wiring diagrams are presented& 1) The input signal is fed to
the input circuit of the amplifier and the amplified voltage of
the frequency difference is taken from a tapping on the oiit-
put coil with a parasitic condenser in parallel. The pumping
signal is given by a non-linear capacity such. as a p-n juntion
transistor typeIT- 403 (P-403) tuned to the frequency of the
supply signal. The power requirement is then 20 + 30 mv. 2) The
amplification-can be increased by a factor of 1.5 when the
signal. is fed from the generator by mutual inductance, the ge-
nerator coil and output coil being some 3 to 4 mm. apart. The
power required is then up to 200 mv. The unit is built on a
duralumin chassis 95 x 75 z 60 mm. There are two alternatives
for connecting.the amplifier to thejT-T~ (PTK) unit, either by a
coaxial cable from the output of the unit to the tapped cutput
soil of the amplifier, the tapping being found experimentaily
and the screen being earthed close to the earthing point of
the coil, or by connecting the output coil of the amplifier t,)

cable. Detailed information is given for the winding of the
coils, e.g. size of coils, type of wired number of turns. The
p-n junction transistor used as variable capacity should be
chosen so that it has the correct characteristics and, in par-
t1cular, the capacity should not, chanGe by more than a factor
of 2 when the applied voltage varies from 0 to -3 volts. The
average capacity should not exceed 8 to 9 pf. A step by step
description of the tuning of the amplifier is given uadng a
0 to 300 Mc/s signal generator and a dpo. voltineter on the i
volt scale. It is suggested in conclusion that amateurs having
built a parametric amplifier of fixed frequency may wish to
have one tunable over a frequency range of say 47 to 57 Mc/s.

PERIODICAL: Radio, 1957, Nr 4, pp 12-13 (USSR)
ABSTRACT: On the occasion of the 30th anniversary of DOSAAF, the Sverdlovsk
Radio Olub was awarded the "Za aktivnuyu rabotu" (for efficient work) badge.
Membership in the Sverdlovsk radio club is over 450. This is one of the oldest
clubs of the USSR. Many of its members, like Kozlovskiy, Dedyulin, Portnyagin,
Znarnenskiy, Zolotin, and others, took part in the defense of the USSR during
World War II and were distinguished with high .- State - awards. Eight
branch offices of the Sverdlovsk radio club are mentioned in the article. Con-
siderable attention is paid to the training of radio operators and radio techni-
cians. Margarita Karavayeva, who works as a radio operator with the - mer'-
chant fleet, Kamchatka, is an alumr,& of the Sverdlovsk Radio Club.
Old short-wave hams, like Zolotin (UA9DP), Kozlovskiy (UA9CF), and
Blokhintsev (UA9CL), have been on the air since 1927 in Sverdlovsk. During
the thirty years of their activities, they have established tens of thousands of

two-way contacts with all continents and with many countries of the world. Of
thd younger radio hams, Semenov (UA9DN), Os'mushin, Tyshinikyi, Kozlov,
and Pervushin are noted. Women radio hams Peresadina (UA9i5F) and Semenova
(UA9DA) have their own radio stations - The latter won first prize in the 1955
woments contest. A considerable development in ultrashort-wave radio ama-
teurism is noted. There were no ultrashort-wave stations in Sverdlovsk oblast
in 1946. There were fifty-nine individually owned and ten collectively owned
ultrashort-wave stations as of December, 1956. Regular two-way radio com-
munications on 38-40 mc, over distances of 1,500 krn and more, have been es-
tablished with Kaliningrad, Petrozavodsk, L'vov, Stanislav, Shaulyay, Vitebsk,
Tashkent, and other cities in the USSR. There were 204 exhibits built by the
members of the Sverdlovsk club and displayed at the oblast Tadio amateur exhi-
bition in 1956; eighty-two of them were cited and awarded various prizes. Re-
cently, a Bulgarian engineer, Nikolov, asked for a description of the device
built by a Sverdlovsk radio amateur, Kolosov. The device, which helps in the
balancing of rotors for electrical machinery, was actually used by Nikolov in
one of the Bulgarian factories. Other radio amateurs cited in the article are
