Thefriation coefficient.of.caprone depends on load and speed# as
indicated by graphs. It is highest at low loads. The wear ot capro-
ne inserts increases with the hardness of shaft. Cast iron shaft
exhibits a smaller friction which is apparently due to greater po-
rosity of former and also on account of lubricating properties of
its graphite. The friction in caprone is lower when AK-10 oil is
used than when lubricating with "IndusTrial 20". The minimum fric-
tion and wear take place during work of caprone with grease. The

ABSTRACT: Methods are proposed for increasing the wear resistance of the upper piston
rings in tractor engines by carburizing the chrome-plated surface. The surfaces of th
rings and cylinder were knurled before chrome plating. The knurl depressions were
tetrahedral pyramids with a base of 0.5xO.5 mm located 2 mm apart with a depth of 0.1&
-0.25 mm. After chrome plating, the rings were chemically heat treated in a solid car.
burizer of the following composition: carbon--50%, Na2C03-20%, Fe (filings)-309:
The heat treatment was continued for 5 hours at 9500C. X-ray structural analysis
showed a gray layer of chromium coxbide on the metal surface. This layer was 60-80 P
thick and was not etched by a 3-4% solution of.HNO3 or a 15-20% solution of HC1. The
carbide layer is heat- and acid-resistant with a hardness of 1400-1600 kg/cm2. It was
found that carburization increases~the service life of chrome-plated piston rings by a
factor of 1.3-2.2. The article was presented for publication by A. I. Pogorelov, Lec-

ABSTRACT: Earlier the first author investigated double chlorides
(Ref 1) and nitrites (together with G. V. Medoks, Ref 2)
of' the elements of the group in question with the corresponding
tetraphenyl-phosphonium. (Refs 3-5). Later Medoks (Ref 6)
icolated double nitrates of lanthanum, praseodymium, and
neodymium with triphenyl benzyl phosphonium. In continuation
of the above mentioned papers the authors included the
methylamine-dimethylamine- and trimethylamine chlorides
in their investigations. They intended to.clear up the
nature of the complex formation of the chlorides of rare
earths with the corresponding salts of the amides in
question in the presence of water and in nonaqueous media
according to their degree of substitution. As an introduction

in the presence of 96~6-ethyl alcohol, the formation of
which is dependent upon the relative amounts of the
substancesentering interactionand upon the crystallization
conditions. As a result of the conducted work double
chlorides of rare earths with trimethylamine in the presence
967o-ethanol were produced. They correspond to the general

TEXT: A study was made as to the possibility of obtaining water-aol4ble
Te from anodic copper electrolytic slimes by producing a definite'comp6sitiort of

lixiviation of the clinker if remains 0 in ihe cake. Calcination of'the ollnke-r
in a stream of C02 or N2 at 700 - 750 C affords the possibility of transforming
70% and = of the Te into the tetra-valent, soluble variety. The reduction of
Te to Te by carbon monoxide occurs at lower+Wperatures. In the laboratory
investigations the transformation of Te into Te oonstituted 80 - 90%.

TITLE: Inveitigation by the Gamma-Locatio.n Method of Some Re-
gularities in the Jigging Process (Issledovaniye nekotorykh
zakonomei-nostey protsessa otsadki metodom gamma-lokatsii)
PERIODICAL: Gornyy Zhurnal, 1958, Nr 1, PP 53-56 (USSR)
ABSTRACT: Numerous versions of the "marked atoms" method employed at
present do not make possible the study of the kinetics of
the spatialmotion of grains in media with different ab-
sorption coefficients. Therefore, the Chair of Concentra-
tion at the Moscow Mining Institute developed a now method,
named "gamma-location", for the continuous study of mineral
grain motion. Tho gamma-location method makes it possible
to record continuoualy the spatial displacements of a part-
icle under investigation into which a radioactive isotope
with hard gamma-radiation is inserted. The block-diagram
of the equipment is shown in Figure 1. The equipment con-
Card 1/3 sists of the following basic parts: 1) an indicator

rtem; 2) an electronic computer; 3) an oscillograph;
4 a high-voltage stabilized amplifier, and 5) a stabi-
lizer of voltage. The essence of the gamma-location method
consists in that the spatial motion of the grains is brokon-
down into 3 coordinates, by means of special systems of in-
dicators. The motion of the grain along each coorainate is
continuously recorded as a function of time. The indicator
systems consist of standard discharge counters situated
according to a definite system, called "carpets". The
electronic computer converts the pulses into direct current
proportional to their frequency. It consists of several
similar channels corresponding to the number of coordinates
being measured simultaneously. The results permit the dis-
covery of basic laws of grain motion in Jigging machines.
For instance, the graph of the motion of a heavy grain re-
presents a monotonous function (shown in Figure 2) which
indicates that the grain continuously oinks to the bottom
layer. The motion of light grains has a "Jump-like" cha-
racter ahown in Figure 3. Analysis of the results shows

(thickness,and degree of loosening) is a criterion of the
Jigging process which determines the specific weight of
separation and the quality of concentration products. The
intermediate layers serve as a filter which paoseB down
only grains of a definite specific gravity. The filtering
properties of the intermediate layer depend upon many fac-
tors: specific gravity and size of the grains, the magni-
tude of hydrodynamic forces, and mechanical interaction
forces between the grains. The establishment of the effects
of these factors calls for extensive investigations.

ABSTRACT: Experiments were performed in order to investigate the
possibilities of producing single crystals with uniform longi-
tudinal and cross-sectional distribution of impurities by means
of pulling at a controlled rate as well as by pulling accompanied
by constant feeding.of pure Ge into the melt. The raw poly-
crystalline, material with a F of 5-20 ohm/cm was purified by
means of zonal recrystallization under a vacuum of 10-4 mm
Hg, or in a stream of HZ, until it exhibited a ? of 50-.60
Card 1/ 3, ohm/cm. A high-frequency heating apparatus with three

induction units moving back and forth was employed. It was found that single
Ge crystals, grown by the Chokhralskiy method from purified material with
a q of 50-60 ohm/cm in conjunction with mixing of the melt by rotating the
crucible and the growing crystal, can achieve ? and -Cvalues of 60 ohm/cm
and 1000 ~t sec, respectively; if the rotation is omitted from the growth pro-
cess, the ? and the -C amount to 25-50 ohm/cm and 200-250 ,a sec, respect-
ively. The UVM-2 apparatus, employed in the process of pulling the crystal
under vacuum (10-4 mm Hg) in accordance with scheduled variations of the
rate of pulling, utilizes a hydraulic raising mechanism which provides a
smooth variation of the elevation rate from 0.05 to 8 mm/min in conjunction
with the rotation of the crucible and the growing crystal. The 9 value of
grown crystals 50 mm in diameter and 180 mm long deviated from the mean
value of rU 40-60 ohm/cm, at a length of 100- 150 mm, by 8.9-9.35o and was
within the limits of error of rneasuiement. It is pointed out that because of
variations in conditions of crystallization only macrouniformity in the distri-
bution of impurities can be achieved by this method. The variations were
eliminated in another device which was designed for a process in which the
pulling is accompanied by feeding of pure Ge into'the melt. Prior to im-
mersion into the melt, the feed ingot passes through a heating unit (composed
-of a quartz tube wound with W wire), while the ingot being pulled passes
Card 2/3

137-58-6-12122
Progress of Work on the Refining of Germanium (cont.)
through a water-cooled unit made of stainless steel. The process of pulling
was carried out in an Ar atmosphere. The fact that the feed ingot and the
growing crystal, which may rotate, were placed excentrically with respect
to the axis of rotation of the crucible, contributed to a better mixing of the
melt contained in the crucible. It was found that the longitudinal q fluctua-
tions in single crystals obtained by this method did not exceed t5lo,
whereas in the case of a crystal produced in this apparatus without the em-
ployment of pure Ge the scatter amounted to � Z4%. Studies of crystals
with a diameter of 50 mm have revealed that the ? was sufficiently uniform
throughout the cross section of the crystal and that the diffusion-path length
of minority current carriers did not deviate by more than 10-1516. The
authors express the opinion that intensive cooling of the growing crystal,
which results in the achievement of a plane crystallization front, contributes
to uniform distribution of electrical properties throughout the cross section
of the crystal. Grown single crystals which exhibited nonuniform cross-
sectional distribution of were subjected to heat treatment in order to bring
about a redistribution of values; in the process the mean value of resistiv-
ity remained unaltered, while the diffusion-path length of the minority cur-
rent carriers increased somewhat. I. Germaniurn--Proc es sing 2. Germanium--Crystalli-

ABSTRACT: An examination is made of the eqdipment and the results. ob-
tained in growing single crystals of Ge by the Chokhral'skiy
,method and by drawing with feeding of additional substance.
Drawing was performed by means of an apparatus consisting of
3 parts. At the bottom there was mounted a vacuum circulation
chamber, connected with a system for evacuation. Water-cooled
electrodes, to which were mounted a graphite slit heater and
screens, were introduced into the chamber. Into the chamber
from beneath there was introduced a motor-rotated rod carrying
a crucible base, A quartz beaker with a viewing tap was placed
atop the circulation chamber on rubber gaskets. The beaker was
Ca rd 1/2 closed at the top by a water-cooled cover, to which was mounted

Equipment and Methods of Growing Single Crystals of Semiconductors
a mechanism for raising and rotating the seed - crysta 1- carrying finger passing
through the cover into the chamber. The apparatus provided a vacuum of NIO-4
mrn Hg. The cover and lower charnber were connected by bolts for operation
in a gas atmosphere. It is noted that in order for a single crystal to be grown
the ternperature of the melt should increase from its center toward the bottom
and the walls of the crucible; some degree of overheating of the melt tends to
increase the reliability of single crystal formation. To produce a single cry-
stal, the seed crystal has to be fused along the entire interface between seed
crystal and melt. Rotation of the crucible and the growing crystal is conducive
to symmetrical growth of the crystal, but when the rate of crystal rotation is
N350 rpm, formation of a screw-shaped crystal is observed. There is a brief,
examination of the distribution of impurities in the drawing process. Ghanges
in the apparatus to permit feeding of additional substance are described. The
crystal being fed is passed through the heater, while the cryst3l being drawn
passes through a cooler. This apparatus made it possible to obtain uniform
longitudinal distribution of Inl I'f along the single crystal drawn when a melt
of pure Ge was fed in. This was verified by autoradiograph photometry and by
resistance measurement (resistance variations of :L 5%). The importance of
good mixing of the melt on drawing with feeding of additional substance is
noted. 1. Single crys-tals--Growth 2. Germanium crystals--Growth Yu.Sh.

ABSTRACT: Germanium with eloctroii-type conductioii and a specific
resistance 25 to 30 ohm/cm was used together with zone
refined antimony and indium. Crystals were pulled from
tile melt. Results nre given in Table 1. All tho samples
had electron-type conductivity and samples with high InSb
content had a higher concentration of electrons than those
with low'InSb content. The number of current carriers
varied from 1.2 x 1018 to 1.9 x lol9/cl,13. The value for
fully compensated additions is 2.5 x 1013/cm3. Thus there
wasan excess of Sb atoms. Experiments were carried out
using the same Gc:Sb ratio and increasing tho In content.
Results are given in Table 2. With a ratio of In:Sb of
2.5 there is still electronic conduction very near to the
compensated alloy. With In,.Sb = 4.11 there is hole-type
Card 1/2 conduction. Microstructures were examined along the

length of the crystal pulled from a melt. A second
phase appears (see Fig) which from microhardness,tests
corresponds to InSb. It does.not appear, however, at
temperatures greater than 650 C - the temperature of
dissociation of InSb. The authors conclude that because
of dissociation of InSb in fused germanium, the system does
not possess the properties of a quasi-binary system.

TITLE: On the electric activity qf tin in germanium

ABSTRACT: In view of the contradictory data on this subject,'the
authors attempt to ascertain the electric activity of tin in ger-
manium by employing a theory of 11. Reiss (J. Chem. Phys., v. 21,
1209, 1953), from which it follows that when the ionizaLion.condi-
tions of the doping atoms change, an accompanying change takes
place in the distribution coefficients of these elements between
the liquid and solid phase.. Thus, iftin is a donor, then its addi-

tion to germanium doped with an acceptor element should cause an
increase in,tbe distribution coefficient of both the tin and of
the acceptat element. The acceptor element employed was gallium.
The germanium single crystals were grown by a procedure described
in detail elsewhere (FTT, v. 5, 1601 and 1100, 1963). The gallium
concentration was determined by llall-effect,measurements. ~he ob-
data on the concentration of gallium and tin in the solid
phase were used to calculate the distribution coefficients and to
.plot the dependence of the distribution coefficients of gallium
and tin on the ratio of these elements in the liquid phase. The
results can be interpreted 6nly by assuming that tin is not elec-
trically neutral and that its donor nature is due to the unusual,
dependence of the distribution coefficient of gallium on its con-
centration in the melt. This explains also the disparity between
the theoretically, calculated and experimentally measured distribu-
tion coefficients of gallium, for the calculations were based on
the assumption that the tin is electrically neutral. It is there-
