were made with Fe-, Co-, and Fermalloy powders, as well as
with mixtures of these substances. Figure 2 indicatesthat the
non-magnetio inclusions have an effect upon both coefficients
of the law (1). The effect of the non-magnetic inclusions
upon the variation of the coefficients A and B depends on
the type of ferromagnetism and the size of the powder parti-
cles. The author thanks V. V. Parfenov for his assistance.

TEXT. The aim of the investigations was to find methods of
heat treatment which ensure high magnetic properties in hot rolled
sheets of iron alloyed with 16% Al. The alloy~O 16 (Yu16),d
corresponding to the American "alphenol", was produced in an open
100 kg capacity induction furnace using as charge materials pure
iron and refined grades of Al. Prior to alloying with Al, the
melt was treated with a vacuum of 10 to 15 mm Hg col,, for the
purpose of decarburization and deoxidation. The metal was poured
into metallic moulds and heated to 5000C. To eliminate thermal
stresses and cracks, the ingots were cooled from 8000C with a speed
of 80 to 90OC/hour. The specimens had the following composition
in percent.- C 0.009, Si 0.38, Mn 0.03, S 0.002, P 0.004, Cr traces,
Ni 0.04, Cu 0.02, Al 15.7. The hot rolling was by means of a 2-high
mill in packets consisting of sheets of dynamo steel and of the

alloy Yul6. Discs of 30 and 20 mm diameter were stamped from hot
rolled 0.35 x 600 x 1200 mm pickled sheets. The specimens,
consisting of 20 sheets, were air annealed in a silite furnace
in the temperature range 800 to 1200*C, followed by cooling at a
rate of 1000C to the quenching temperature, held.at that temperature
for 30 min and then quenched in a 20% NaOH solution, water or
transformer oil. The magnetic properties were measured ballistically,
the electric properties were measured by means of resistance bridges.
For determining the influence of the annealing temperature on the
magnetic properties, the specimens were cooled at the rate of 1000C/hr
and then quenched in the alkali from 600*C. An increase in the
annealing temperature from 850 to 1050*C brings about art improvement
of the magnetic properties. On increasing this temperature further,
the magnetic properties will become somewhat poorer. An increase
in the annealing temperature leads to some burning off of the Al.
The quenching medium and the quenching temperature have a consider-
able influence on the permeability and on the coercive force; the
highest ji0 values were obtained after oil quenching from 650*C

(annealing at 9500C) and 7000C (annealing at 10500C). An increase
in the annealing temperature shifts towards higher temperatures
the optimum quenching temperature from the point of view of 40.
The initial permeability is considerably lower for specimens
quenched in alkali and water. For obtaining high maximum permeabili-
ties it is necessary to quench the alloy from 6500C (after annealing
at 9500C) and 6oo*c (after annealing at 10500C). An increase in
the annealing temperature and the quenching speed leads to a decrease
in the optimum quenching temperature. In the case of oil quenching,
the coercive force decreases with temperature up to 650-700*C. It
was found that an increase in the quenching temperature and the
cooling speed leads to an increase in the electric resistance and,
consequently, to a decrease in the degree of ordering. An increase
in the soaking time from 15 min to 3 hours during annealing and also
of the cooling rate from 50 to 200*C/hr does not affect greatly the
magnetic properties. The results show that with this alloy magnetic
properties can be obtained which compare favourably with those
obtained for an iron alloy with a 50% Ni content. Acknowledgments

temperature and the appropriate curves show a pronounced
maximum (or0minimum). The residual induction has a maximum
at 20 - 40 C and shows little dependence on the heat-
treatment conditions. At low quenching temperatures (400 -
500 OC) and high cooling speeds, the magnitude and the
temperature stability of the magnetic properties are low.
The highest initial and maximum permeabilities were obtained
in tests at 100-120 and 40-60 0C after annealing followed
by oil-quenching. Artificial ageing at 50 - 100 0C resulted
in an improvement in the magnetic properties by 5-20%. The
results have shown that heat-treatment, which leads to
improved magnetic properties of the alloy, brings about a
decrease in the temperature stability of these properties.
An increase in the cooling speed during quenchin� narrows
the range of operating teifipetatures; at 15&180 C an
irreversible deterioration in th8 magnetic properties will occur.,
Artificial ageing at 50 And 100 C improves, and artificial
ageing at 200-250 0C reduces the magnetic properties of the
investigated alloy. Natural ageing for periods of four and

TITLE: An Unusual Motor (Neobychnyy dvigatelf)
PERIODICAL: Tekhnika molodezhij 1958, Nr 9, PP 37 - 37 (USSR)
A13STRACT: In the course of their studies at the Leningradakiy
elektrotekhnicheskiy institut imeni V.I.Ullyaneva (Lenina)
(Leningrad Institute of Electrical Engineering imeni
V.I.Ullyanov (Lenin)) the authors of this paper invented
an electrical motor which they called "dielectric
motor". This is a description of its principle of operation.
This motor has neither a conventional steel stator with
a copper winding nor a massive rotor. It operates by
using the principles of static electricity - the interaction
of stationary electric charges. The disk does 6000 revs/min.
Attempts were made to increase the speed of the motor
by producing the rotor from different materials. The best
results were obtained with plexiglass. The speed can also
be increased by placing the rotor in a vacuum, thus
Card 1/3 reducing air friction. The power of the motor can be increased by
An, Unusual Motor SOV/29-58-9-26/3o
placing it in a high-pressure chamber . In a fluid di-
electric the nominal voltage is reduced almost by a factor
of 10. As a compensation the speed is considerably reduced
owing to the increased friction of the rotor in the fluid.
The dieelartric motor is still anything but perfect. Never-
theless it is capable of being used in practical work.
If a vane is attached to it it may serve as a ventilator.
If the shaft of the rotor is arrested by a spring this
motor is transformed into an instrument measuring high
d.c.tension. The angle of deflection of the rotor will be
proportional to the potential applied to the electrodes.
The high speed of such motors and the lackine of a
commutator recommends such motors for use in gyroscopes.
Although at present it may sound phantastically, there is
no denying that in princ4ple such a motor could be used
in connection with a radioactive electrostatic generator.

the presence of sulfur quenched it. The cathodoluminencence of all the specimens ex-
hibited a characteristic band peaking at 380-400 r4A. Blectroluminescence was excited
by fields of the order of 10 4 V/cm in a cell equipped with brass and conducting glass
electrodes. No luminescence appeared when the field was first applied, but if the
glass electrode was negative and the polarity was suddenly reversed there appeared a
flash with a duration of no longer than 1 see. The flushes produced by subsequent
field reversals decreased in intensity, and no electroluminescence was observed in
alternating fields with frequencies of 20 liz or higher. The brightest electrolumi-
nescence was obtained with an AIN:Eu:Zn:S specimen; its spectrum exhibited the two
bands characteristic of the photoluminescence of AlN:Eu (narrow bands at 380 W and
357 qL) and a broad band in the 270-300 mp region. After a brief discussion of the
possible mechanisms giving rise to the electrolumineseence it is concluded that

plasticizer must swell to the maximum for PVC foam pastes. Dry C02 and

ABSTRACT: In modern theories of electric breakdown of solid dielectrics
it is supposed in accordance with experiments that the break-
down is conditioned by the behaviour of the conduction
electrons in the crystal lattice under the influence of a
strong electric field,, New dielectrics were recently syn--

connection, the temperature dependence of Ebr was investigated

and a temperature dependence of 6 , being represented by
titanates of zinc ZnO TiO (F -30), of calcium CaTiO, (EE -130),
of barium BaTiO (r- .10005 and by SBT (E .8oo).(The V"alue of

The maximal errors in the determination did not exceed 12%.
Mean and maximum values for Zn, Ca and Ba titanates and for
SBT are given on a table. The dielectric strength of the
investigated polycrystalline dielectrics does not change with
the duration of voltage application at room temperature
(figure 2). A certain correlation exists between the
temperature dependence of C- and the breakdown voltage (figures
3 and 1). A higher breakdown voltage corresponds to smaller
values of,E , although the temperature minimum of E, and the
maximum of 6 do not coincide. R 0:C

(figure 4). The examinations of the theory of electric
breakdown in solid dielectrios proceed from the conception
of impact ionization by electrons in a mediuin electric fi-ld.
The disturbance of electron distribution is a consequence of
the avalanche-like accumulation of conduction electrons in
the crystal lattice. The interrelation between electric dis-
ruption and the polarization effect (frequency, effective
ionic charge) can be caused by energetical losses of the
conduction electrons on lattice vibrations. The effects of
polarization on the magnitude of dielectric strength of the
dielectric must be caused by the energetical losses of the
electrons on the vibrations of the basic lattice ions (atoms)
as well as of the ions causing a polarization accompanied by
an high dielectric, permeability., Moreover a strongly effective
field is in a position to modify the frequency of the basia
ions into either direction, which will show in the energy
losses of the conduction electrons,, From this viewpoint it
proves to be extremely difficult to obtain an analytical
representation of the dependence of dielectric strength on
Card 3/4 dielectric permeability and makes necessary special investigations.
On the Temperature Dependence of the Pulsed Dialectri(., 48-22-4-11/24
Strength of Some Polycrystalline Dielectrics
The representation of the interrelations between dielectrio
strength and dielectric permeability must be examined and
proved with pure monocrystals, The authors performed
experiments with polycrystalline samples- For this reason
the here investigated dependence is rendered more complicated
by secondary effects, as caused by macroscopic heterogeneity
of the substance (crystallites', vitreous layers, pores etc.)~
A final answer as to the nature of the temperature dependence
of dielectrio strength on dielectric permeability can
presumably be achieved by means of experiments with mono-
crystals. There are 6 figures, 1 table, and 11 references,

TEXT: The authors present some methods of irradiating solids by slow
neutrons from a nuclear reactor with a view to studying the resulting
dielectric properties. In earlier works (Vodoplyanov L. K. and
Skanavi G. I. "Izv, AN SSSR", ser fiz., 24, 253-257, 1960) they had
measured the past-irradiation di.electric properties of titanates of the
second group in the periodic system, add of alkali halides. Platinum
electrodes, applied to the specimens by evaporation coating, proved to be
the most stable. The samples were sealed into aluminum containers and-
placed in special cavities in a heavy-water test reactor. The specimens
in the container must not be allowed to screen one another. The specimens
were 8ubjec-ted chiefly to slow and fast neutrons and to gamma rays.

In ord.er to irradiate the specimens with thermal neutrons with a low
enough percentage of fast neutrons, teat channels in the reflector of the
reactor were used. Cadmium filters were used to absorb the thermal
neutrons, so that the effeat of the fast neutrons and of gamma-background
alone could be'studied. All samples irradiated by thermal neutrons showed
considerable beta and gamma activity. V. S. Vavilov and S. A. Gavrilov
are thanked for discussions and collaboration. There are 2 Soviet

ABSTRACT: An investigation was made of the dependence of electric conductivity on
the temperature and concentration of the impurities introduced into a layer of diamond
doped with lithium and boron by ion bombardment. Diamond doping was carried out in a'
ion-ray installation with a magnetic separation at a focusing angle of 180% Lithiuml
and boron ions with an energy of 40 kev were introduced into the natural face of the
crystal or into the cleavage plane perpendicularly to the crystallographic directionsi
(111) and (100). The activation energy for lithitim was (0.29 1 0.01) ev and for borork I-
(0.25 t 0.01) ev. Lithium-doped diamond has an electron-type conductivity, while ini
boron-alloyed diamond the holes are the major charge carriers. Annealing of specimensi
at 600C for three hours in an argon atmosphere had virtually no effect on the activa-;

tion energy of electric conductivity; the general resistance of the doped layer in-
creased somewhat only in the case of boron. The acceptor and donor levels appearing
in the forbidden band as the result of radiative defects are deep and have only a
slight effect on the activation energy. With an increasing concentration of lithium,
the activation energy decreases in the range of high temperatures as well as in the
range of lower temperatures. These rules apply to the impurity band, in which the
concentration of lithium is about 1020 cm-3. Ion bombardment makes it possible to
obtain semiconducting layers of diamond whose electric conductivity can change by
5 to 10 orders, depending on the extentof doping. The energy level corresponding to
the lithium admixture is separated by 0.29 ev from the bottom of the conductivity
band, while the energy level of boron is 0.25 ev from the top of the valence band.

ABSTRACT: An airborne apparatus and a method for simultaneous measurements of polar
conductivities of both signs under clear weather conditions arc described. The in-
strument is based on Gerdien's principle, employing two identical cylindric capacitorf
as measuring units. The change of the zero point current is analyzed and shown to be
caused by the charge of the metal electrode by coarse aerosols. A procedure for
eliminating this effect is presented. Deviations due to air turbulence are shown to
lower the magnitude of ion concentrations in the capacitors by approximately 8% and
to influence similarly conductivity. Analysis of data obtained over the Ukraine,
Siberia, and the Far East region indicated that the ratio 1+/X- > 1 in the lower
layer of the atmosphere, decreases with an increase in altitude ' and changes to
values below unity at heights depending on conditions. In concLsion, the author

ABSTRACT: An attempt at a qualitative and quantitative comparison between the
intensities of world-wide radioactive fallout over the oceans and continents was
carried out through an estimation of accumulated Sr90 at the same latitudes In aunit area
of the ocean surface snA a unit area of continental surface. The results of direct
measurement of radioactive-fallout intensity on the continents and on the islands and
the data on the cuncentration of radioactive fission products in the air above the sea
surface and above the surface of dry land were also taken into consideration. On the
basis of these data, it is supposed that the intensity of radioactive fallout over the
sea surface is ater than over dry land. Orig. art. has: 5 tables and 4 figures.

ABSTRACT: The results are summarized of deep seismic sounding conducted in 1960 to
1962 along a 300-km submeridional profile between Stepnoye and Bakuriani and a
700-km sublatitudinal profile extending along the axial part of the Transcaucasian
intermountain region between the Black and Caspian Seas. Continuous, piece wise
continuous and point profiling methods were used. The analysis of data shows that
the Earth's crust, 32-km thick in the region of El'iehotovo, increases to 38-40 km
in the area of Stepnoy-Nizhniy Kurp and to 42-46 km in the southern part of the
profile. The boundary velocity along the Mohorovivic discontinuity determined
in the area of Nabakhtevi is 8.4 km/sec. The depth to the top of the consolidated
crust with a boundary velocity of 6.km/sec varies from 7 km in the Zaterechnaya

Plain to 300-400 m at Rokskiy Pass. Although the interfaces within the crust were
not determined, seismic data appears to indicate a layered structure. The thickness
of the Earth's crust along the sublatitudinal profile varies from 40-41 km at
the western end of the profile and near the city of Kirovabad to 47-49 km under the
Dzirul'skiy. massif and east of Lake Dzhandar. The boundary velocity is 8 km/sec.
The boundary velocity along the top of the consolidated crust is 5.8-6.2 kmfsec.
The depth to the top of the consolidated crust varies from 0 (Dzirul'skiy massif) to
12-15 km in the area of Barda-Agdzhabedi. Two interfaces with boundary velocities
of 6.7-7 and 7.2-7.5 km/sec were established within the crust at a depth of
10-20 and 30 km, respectively. Sharp variations were established in the ratia of
the thickness of granitic to basaltic layers along the sublatitudinal profile. A
downwarping of the Mohorovicic. discontinuity under the mountains along both profiles
is noted. The results obtained are in qualitative agreement with earlier geophysical
investigations. However, deep seismic-sounding data indicate a downwarping of the
Mohorovicic discontinuity under the Dzirul'skiy massif, while gravity data indicate
upwarping. The article contains 7 figures including a map showing the locations of
the profiles, a rough seismic cross section along the submerldional profile, a
seismic cross section along the sublatitudinal profile and three other seismic-
geologic cross sections' of the same general area compiled from seismic and gravity
data by other investigators. Orig. art. hast 7 figures. (VA-7941

ABSTRACT: The correlation method of refracted waves was used in the investigation
of the structure-of the crystalline basement along a 60-km profile running between
Anaklia and Zestafoni along the Rionskaya and Kolkhidskaya lowlands as far west as
the Dzirul'skiy massif. A refracting seismic horizon with a boundary velocity of
5.7-6.3 km/sec was identified as the -surface of the crystalline 'basement. Several*
blocks separated by subcrustal faults are found in the basement along the profile.
Each block is characterized by a boundary velocity and probably by a slightly
different petrographic composition. Although the scope of the investigation did not
include a study of the structure of the subbauement, it was established that *the
Earth's crust along the profile consists of 3 layers with layer velocities of

3-7.2 km/sec. The approximate depths to the interfaces are 3, 6, and 10 km. The
gravity data were used in preparing a cross section showing the depth to the
Mohorovicic discontinuity, which varies between 45 and 46 km along the seismic
line. The article contains 4 more figures including a cross section of apparent
velocities along the seismic profile down to a depth of 27 km. (WA-7941

alloys, the decomposition process also occurs by diffusion; how-
ever, when alloys containing 6 - 10 percent V are cooled at a
rate of 5 - 6 deg/min the process of the T assumes a
non-diffusive martensite character. At identical cooling rates
the W T in a 4 percent V alloy is of intermediate nature,
but ctnges to a martensite nature when the cooling rate is in-
creased. From the results obtained it is concluded that both the
kinetics and the mechanism of T in a super-cooled gamma phase
of the' alloys investigated may be interpreted by means of the
usual theory of decomposition and martensitic transformation.

ABSTRACT: Hardness, microstructure, critical points, and magnetic
properties were investigated in Alloys containing 50 percent Co
and 2 percent V. V substantially affects the critical points of
alloys of the Fe-Co system, by lowering the temperature of the
oZ -'-C- t transformation. The microstructure of slowly cooled
alloys exhibits a characteristic grain lattice, probably due to the
phenomenon of orderly regulation of grains. The hardness of
cold rolled specimens is considerably increased by heating to
400-6000; any further increase in temperature reduces the hard-
ness due to incipient - ' r ecrys tall iza tion. Initial permeability
is strongly affected by the degree of reduction in the process Of
cold deformation. Optimal results are, apparently, obtained at a
