ABSTRACT: The archeological expeditions of the Uzbek ~;tnte University
discovered many coves, among them the Amnn-Kutnn Cave at
1,200 - 1,800 m above sea level, where many excsvstions were
made between 1953 and 1955. The animal bones and other re-
lics found under travertine layers point to the fact that
early men had lived in this cave. Judging from the stone re-
lics, the period this cave was used by man must be dated back
to the Miousterian. Among the recovered items, arms made of
quartz with attachments for wooden handles at the edges, are
of special interest. The animnl relics can be dated back to
the '~'uaternary fauna. The discoveries show thnt there was
a stable climate ir, te wAhem MOUntain- regions of Uz~,ekintnn.

TITLE: New transducer designs for measuring pressure in an
oil layer of a fluid friction bearing
PERIODICAL: Vestnik mashinostroyenlyat no. 12, 1961, 22 - 26
TEXT: The authors describe new pressure transducers used during
investigation of heavy loaded bearings, where the oil film was
only 2 - 3 p thick. The following prerequisites were found indis-
pensable to ensure the accuracy of readings: The assembly of the
transducer should not interfere with the friction surface, or re-
duce the rigidity of the shaft, it must also be simple and easy to
replace. The measuring area must be small-1, but the sensitivity
high. It must have linear characteristics (together with its ampli-
fier and oscillograph). The calibration of the system should ap-
proach actual working conditions, and hold it during the process
of mze~_surement. Application of electric erosion permits the

tion of diaphragns with the required thickness -.n .he surface or
the heat treated shaft, and with a diameter of 5 - 8 mm. The niezu-
electric transducer uses a spring loaded ceramic olement of mi_.tarl-
iobate of barium or lead, whereas the strain L!-aui-e employs a t.-i-rea-
ded probe made of 60 C['A (60 SGA) steel. The first transducer has
a greater sensitivity and stiffness, but is somewhat more Involved.
The diaphragm is supported by the transducer and thus deCreases
errors of readings, because the deformation depends upon the rigi-
dity of the transducer, diaphragm and the joints. The small size of
contact area allows 0.08 - 0.16 of the distributed load to be con-
sidered as a concentrated force acting on -the diaphragm. The re-
sults of experimental measurements of deformation of the ~,enter in
the latter are plotted. In the case of 8 mm diameter diaphragm,
1.5 mm thick and supported by the traneduceri this deflection was
below 1 - 2 la with a distributed load of 500 kg/CM2. There is, how-
ever, a shift in the surface layers of the shaft due to the dist.r.-
buted pressure of oil film in the bearing. In practice they are
compensated by the displacement of the diaphragm center. The thin
diaphraGms are not expedient, The grea-u sensitivity o.'IC piezo mate-

rials balances the losses due to thick diaphragms. The available
data recommend a thickness of 0.8 - 1.5 mm for diameters of 5 - 8
mm. Recently, use has been made of such materials as stannates, ti-
tanates and niobates of lead and barium which possess stable cha-
racteristics within a wide range of temperature. The piezo effect
is determined by the piezo-modulus d33. Tests were carried out to
establish these properties. The experiments proved that the piezo-
electric constant of solid solution of metaniobate of barium in
metaniobate of lead does not vary between 20 and 1200C, and is 40
times higher than the constant of quartz. The high piezo-effect of
this material, its mechanical strength and large modulus of elas-
ticity permit the construction of highly sensitive pressure trans-
ducerB. The calibration jig consisted of an oil pump, manometer
and a clampp fixed on the shaft opposite to the transducer. As the
Curie temperature point of the above piezo material is about 3500C,
it is ponsible to consider a higher operating temperature for test-
ing fluid friction bearings. A description is given of the test
stand and oscillograms are quoted indicating the results 0. inves-
tigationa. The latter confirmed the adequacy of the proposed arran-

PERIODICAL: V sb.: Elektr. i ul'trazvuk. metody obrabotki materialov, Leningrad,

ABSTRACT: The author points out that electric pulse generators applied for electric
spark treatment are divided into relaxation and independent ones. When
the generators are operating under rough conditions, a net of micro-
fissures is formed on the treated hard alloy. Besides, relaxation generators
are uneconomic. The electric spark laboratory of the Lenkarz plant con-
structed a high-power generator of 10 microsecond pulses, which makes it
possible to Increase considerably the efficiency in treating hard alloys.
The block diagram of the installation is given as well as data on the
selection of its parameters. When testing a circuit based on the LKZ-184
Cax,d 1/2 electric spark machine a frequency of 1,000 to 1,700 cycles was obtained,

while the output at the 6th class of surface finishing amounted to 1 g/min. Moreover
a two-cycle circUlt has been developed which makes it possible almost to double the
efficiency at the same class of finish. It can be assumed that the application of
3 - 6-phase circuits will increase the efficiency up to 2.5 - 5 9/min of hard alloy.

TITLEt An Investigation of Silicate Glasses with Electronic

PERIODICALt Zhurnal Tekhnicheskoy Fiziki, 1957, Vol- 27, Nr 12, pp. 2702
-2703 (USSR)
ABSTRACTs In the investigations of alkali-free silicate glass
conducted here special regard was given to the anomalously
high electric conductivity of glass with iron oxydes. The
electric conductivity of such glass proved to be higher
than that of analoguous glass, which contained a
corresponding amount of sodium oxyde instead of iron oxyde.
The measurements were conducted with graphite electrodes
according to the usual method (reference 7). The character
of the conductivity was determined accordini-- to the "Tuband-
method". Three glass samples, anode, a medium (control) and
cathode samples were carefully ground to fit together and
mounted between metal disks. A constant volta.-e was applied
Card 113 to the disks. A measured amount of current was passed through

the samples (at about 6000 C), which beforehE.nd were weighed.
A judgement can be given on the character of the conductivity
by means of the change in weight. The results showed, that
in the glass under investigation a practically pure electronic
conductivity (experimental error I * 2 ~) is met with, the
magnitude of which is strongly dependent on the Fe 203 content
and on the composition of the glass. It is shown, that
although the glass sample no. 2 contained only 5A of Fe2o 3
it displayed a pure electron conductivity. From this it
appears, that the lattice of amorphous boron-aluminium
silicate remsents no insurmountable obstacle for the
electrons. Glass sample number 2s 45 molar percent of SiO.,
10 molar percent B 20 39 10 molar percent of A120 3P 30 molar
percent of CaO, 5 molar percent of Fe2o 3). It is conjectured,
that probably, a partial or total electron conductivity is
also characteristic for many silicate and borate glass types
free from alkaline contents with a high resistance. There
are 1 figure, 2 tables, and 12 references, 7 of which are

TITLE: The Influence of Alka;i-metal Oxide Additions on the
Electrical Properties of Alkali-free Glasses
PERIODICAL: Izvestiya vysshikh uchebnykh zavedeniy, Fizika,
1960, No 3, pp 43 - 51 (USSR)
ABSTRACT: This Is a continuation of earlier work (Ref 1) - a study
of alkali-free glasses - in which the effect of aluminium
oxide on the electrical properties was investigated. It
is important to know the effect of alkali-metal
impurities in these glasses to estimate the required
purity of the raw materials and the possibility of
deliberate inclusions of alkali-metal oxide in the
recipe to reduce the smelting temperature of the glass
and improve its properties (mechanical, thermal, etc)..
A study of the literature (Refs 1-10) gives a basis for
assuming a special form of interaction of lead silicates
with alkali oxides leading to an increased electrical
resistance.
Electrical resistance of the glasses studied was meai-ured
Cardl/2 by the method described in an earlier paper (Ref 11).

S/139/60/000/03/007/045
The Influence of Alkali-mqtal Oxide AWWOZA35on the Electrical
Properties of Alkali-free Glasses
It was found that borate glasses always have higher
resistance than silicate, while borosilicates are
intermediate, Introduction of aluminium into alkali-
free glasses increases their resistance but the opposite
effect occurs with borate glasses. A calcium-borate
glass had the highest resistance, appreciably exceeding
that of fused quartz. Up to about 5-8 mol.% the
addition of alkali-metal oxides has practically no effect
on the resistance, after which the resistance drops
rapidly. It is assumed that at low concentrations the
conduction mechanism remains that of alkali-free glass,
while above the critical concentration the conduction
mechanism is that of alkali-glass. There are 3 figures,
I table and 20 references, 15 of which are Soviet and

TEXT: The system HgSe - HgTe, which has very interesting thermoelectris
properties, has so far been investigated very insufficiently, and the pub-
lished data are contradictory because the system probably contained al3o

properties of very carefully prepared samples which contained no unreazted
Hg any longer. Hg of the type P-I (R-1) with a purity of 99-9990/o', Se witti a

acy. A study of the deviation of the curvea. f(log n) from the theozetv;al
one shows that there exists a partial degeneracy. Tak1r.I,, the :utter int-i
account, the authors calculated the carrier concentration (n) from thq Hall

carrier mobility (u) on the composition. u had been calculated from R and:,.
Whereas n is almost equal for both pure HgSa and pure UgTe, u la 20,000 for
pure HgSeI and 22,900 cm2/v-sec for pure HgTe. The absence of a A-poInt is
indicative of the absence of a hyperstructure. Many specImenn which had

The anomalous course of curves 2 and 5 can be ascribed either to a nearly

TITLE: Mechanism of carrier scattering in germanium telluride
SOURCE: Fizika tverdogo tela, v. 8, no. 4, 1966, 1212-1216

ABSTRACT: Continuing their earlier work on this subject (FTT v. 7, 223,
:L965 and v. 6, 7o6, 1964), the authors discuss the experimentally ob-
served anomalous dependence of the carrier mobility in germanium tellur-
ide on the temperature and on the density, and conclude that although
the mobilities of the light and heavy holes have the same temperature
varia.tion ( - T-3/5' the difference In the effective rrasoes of the two
types of holes (by approximately one order of magnitude) gives rise to
different temperature dependences of the mobilities and differences In
the dependence of the mobility on the true carrier density. The anoma-
lies are caused by the facts that at different densities the relative

shears of the heavy and light- holes *,ary. The comparison of the experi-i
mental data with -the authors' theory, which allows for two types of
holes, is made under the as3umption that there is no Inteftand scattering
The observed dependence of #the absolute mobility on the concentration ofi
defects in the crystoal Is related to additional ocattering by the screen-,
ed lattice defects, which does not depend on the temperature. It Is
concluded as a result that in germanium telluride there are two simul-
taneously acting acattering mechanisms, by the acoustic lattice vibra-
tions and by the screened defects. The observed anomalies in the be-
bavior of the mobility are due, as in other materials, to the complicated
structure of the energy spectrum of the carriers. Orig. art. has: 2

ABSTRACT: The purpose of the paper in to clarify the influence of thc prerence of
two types of current carrier of the same polarity on the Hall coefficlent when account
is taken of the variation of the energy gap AE with temperature, and to compare the
calculated data with the experimental ones for p~-type PbTe and for GeTc. The change in'
the Rall coefficient with decreasing fraction n 2 of the hewiier carriers (holes), due
to the change in the temperature and simultaneous decrease in the gap AE between the
sub-bands is calculate for several carrier mobility ratios (5, 10, 20). The calcu-
latilon shows that the Hall coefficient 11 ohould go through a maxitaum at a definite
1 ratio n A., amounting to 0.95 and 0.92 for GeTe and PbTe respectively. R increases

with increasing temperaturs (corresponding to an increase in n 2 /nl), in agreement with
the experimental data, but at temperatures above 570K for GeTe and 400-450K for PbTe

its experimental values begin to decrease, &IthouG'Ii thcorctic&lly it should reach a
maximum at higher temperatures. The discrepancy in attributed to the appearance of I
I carriers of opposite polarity, to a change in the overall carrier density due to the
change in solubility of the doping mctali and to inaccuracies in the determination of
the band parameters. Orij;. art. hasi 2 figuren and 5 rormulua,

of curves. On the basis of the data, Une following conclusions were drawn., 1) based
on measurements of the density of samples of known composition, it was found possible
to determine directly the nuz&b r of i vacancies and to determine the true
. .3erman um
concentration of current carrill it was established that in very dilute solutions
k-he solution of impurities takes place only in the vacancies of the cation lattice;
3)'Av~e solubility of impurities in the vacancies is limited, and 13 always less than
the concentration of vacancies; 4) in the presence of-free vacancies, there is the
:possibility oZ solution of Cu, Sb, and Bi impurities in considerable anounta, by the
displacement of germanium in the occupied places in the lattice; 4) the effect of
;'ir,vurities on the thorm4l resistance of the lattice can be explained from the point of
view of the existence of a limited solubility of the impurities in the vacancies, and
by the formation of new dissemination centers which subsequently replace the germanium.'

ABSTRACT: The accuracy in finding a ship's position with radar depends on the
errors in direction-finding and in measuring distances. If the mean square error
in direction-finding Mn exceeds the mean square error in measuring distances ?t,
(Mn > Md, the second method Is more precise, and vice versa. The selection of
optimum methods is illustrated by monograms for particular observed cases at given
mean square errors Mn - tl.O* and Md - t0.25 cable lengths [1 cable length - 608 feet
The monograms are platted from formulas based on equating the mean square errors in
measuring distances to two orienting points and in direction-finding. The case of
three orienting points is discussed. The proposed methods proved their high effectiv
