TITLE: Zone of Oxidation of the Pervomayskoye Molybdenum Deposit

TEXT: The papers by M. M. Besova (Ref. 1), N,. A. Smollyaninov (Refs. 8,9),
and M. M. Povilaytis conoerning the Dzhidinskoye ore fiold hardly deal at
all with the distribution of the minerals in the oxidat:LOD zone and its
morphology. The author studied these problems in 1956-1957 and now gives
his results. Almost all the modern research methods were applied in these
studies. The X-ray pictures were taken at the Irkutskiy institut redkikh
metallov (Irkutsk Institute of Rare Metals) by A. V. Sharonova, while the
chemical analyses were made by V, M. Shcherbakova and L, R, Milf .. CC*9^,rker.--
of the same Institute. In the Pervomayskoye molybdenum deposit in the
Dzhidinskoye ore field the ore mineralization is connecled with the apex
of the stock of granite-porphyries of the Cimmerian intrusive cycle and is

traced back to the Cambrian by way of the biotite-amphibol-le slates and
hornstones containing the said stock. The molybdenum m-fnexalization of th-,s-
deposit is represented by stockwork types, disseminated and vein types.
The main hypogene minerals of these ores, upon which th~- formation of
secondary products in the zone of oxidation was based, are pyrite,
mclybdenite, cha2copyrite, galenite, htibnerite, rhodoch.rositc.,, fluorite,
and feldspars (microlite and albite). The most important and most widely
spread hypergene minczal is jarosite, and less widely spread are feri,ic
hydroxides, and, still less, ferrimolybdite and powellite~ Summ,'.ng -up:
!) Under relatively stable geochemical conditions one may write 'he
following succession in the formation of hypergene minerals in 'the
oxidation zone of the Pervomayskoye molybdenum deposit: molybdenite
powellite, ferrimol.ybdite, molybdenum-containing limonite, limonite;
galenite - anglesite, cerusaite, wulfenitel -.halcopyrite - bornite,
chalcosine, covellite, azurite, malachitel pyrite - jarosite, limonlte;
rhodochrosite - manganite, psilomelane, pyrolusite, 2) As to oxidation
intensity, three molybdenum ore types can b-~? singled out here: a su2fidJ-,,,.
one, with a relative MoO3 content of 0-20A, a s,.i!fJdo,ox4-dt.-,ed onc vvith

a MoO3 content of 20-30',o, and an oxidized ore type with a MoO3content of
over 30% of the total molybdenum conten-- The first and, in part, the
aecond ore type are so far important industrially. 3k) Th? spreading of the
three types in horizontal and vertical direction is irrej,;Ular-~ At the
same time, the intensity of ore oxidation decreases with depth until, at
a depth of 50 M, the ore is almost not oxidized at all, The zone of
oxidation of the Pervomayskoye deposit has formed beginn:-ng from the
Mesozoic to the present time. Papers by N. A, Smolyaninov and Ye~ N.
Isakov (Ref 9), V. A. Obruchev (Ref. 6). and reports by Ye, N. Smolyansk~y

ABSTRACT: Joining of conveyor belts (overlapping Joints) by
vulcanisation according to adopted practice (shown in
Fig 1) required 8-10 hours and therefore u-as seldom used.
In 1956 a new method of joining not by overlap ing but
by interlocking of the individual belt layers Gig 2)
was developed. The ends of the belts to lie joined are
out at 900 and heated by vulcanisation plates to
100-1100c. At this temperature the separation of layers
is easy, but it also can be carried Out OrL cold using a
special tool shown in Figs 3 and 4. The length of the
interlocking joint is 600-700 mm as against 2100 mm of

ABSTRACT: This study involved the improv,%~?nt of physical and mechanical propVties.,
and the weatherproofing of: 1) polyami e~films of uniaxial elongation PK-4* L~;
2) polyv~Wl films with a corplex plasticizer; 3) polyethylenaterephthalic film
PETF-20. Protective varniad"or metallic coating was employed. Two-component poky-
urethanallake, consisting ok polyisocyanate and polyhydroxy compounds, was used-Es-
_:i_ ~nishlcoating; aluminum applied by vacuum spraying was tested as metallic protec-
tive coating. Rigidity,.tonsile strength, elongation at breaking point, and elas-
ticity modulus of treated and untreated films (before and after aging) are compared.
It is concluded that rigidity and tensile strength of treated, films before and after
aging are considerab3,v improved. Elastic properties of the treated films are not
ff ated. Orig. art. has: 3 figures and 1 table.

ideformation of the optical Indicatrix modulates the beam at the ap-
1 plied frequency and the rotation of the indicatrix modulates the beam
at twice this frequency. When the Nicols are set at 450 the si-tuation
is reversed: rotation of the optical indicatrix modulates the light
beam at ike applied frequency and deformation modulates it at the se-
cond hamonic. With the proposed method, therefore, it is possible
accurately and separately to determine the effects of rotation and
deformation of the optical indicatrix. The proposed method was em-
ployed to investigate the electro-optical effect in R)chelle salt.

Abstract In a crystal specimen of rock salt, approximately 100 mx long,
cut in the L116] direction and twisted about this direction
by 900, there was sent a short b1trasonic pulse of shear wa-
ves at a frequency of 1.67 Mc. The receiver of a Y-section
from the other end of the specimen received the ultrasonic
vibrations passing through the crystal, which after aziplifi-
cation were applied to the plates of an oscillograph. It
was shown that the twisted crystal of rock salt rotates the
plane of oscillations of the particles in the shear wave
(plane of polarization) by an angle that equals approkim-

ABSTPACT: In view of observation of anomalies in elastic properties of strontium
titanate, the authors checken on the possible existence of such anomalies in other
perovskite substances, particularly 1QW?3. The crystals were grown in graphite
crucibles in an argon atmosphere. The temperature'dependence of the elastic wave
velocities were determined by pulsed ultrasonic methods at 30 MHz. The temperature
dependence of thewave velocity de.-.reased with decreasing temperature, first slowly
and then abruptly at 2OOK, with ve:ry strong absorption at 180-190K where measurements
could not be. made. An increase vat, then. observed below 180K. Twinning was, observed
by optical means at 180K. A similmr wave-velocity dependence and absorption anomaly
near 180 - 190K was observed in measurecents with shear waves in the [1007 direction.
The anomaly in the elastic properties of' KMnF3 near the phase transition point (184K)
is similar to that observed in SrT;1Oj,&t 110K, but the region of anomalous behavior
is broader in WnF3p beginiiing at 20 25* before the transition point, probably as

not accomapnied by anomalies of the magnetic or dielectric propertiesp it is proposed
that the anomalies are due primarily to changes In the lattice vibration spectrum.
The spontaneous lattice deformation arising in the low-temperature phase can be in-
terpreted from the point of view of Landau's theory of second-order phase transitions
The anomalies in the velocity and absorption of the elastic wave near the transition
can also have a relwmtion character. Orig, art4 has: 1 figure.

Abstract: Descriptiop of an -ultrasonic instr.1ment for the measu--ement of
the elastic moduls of a crystal, based on the measurement of ve-
lo-ity of propagation of short pulses of longitudinal and trans-
Nez-se t-lastic vibrations in small s-necimens. The unknown velocity
is eleterminea by, superimpo8ing on t~e scr-e~n of a cathode ray os-
cillograph two pulses, one passing through the specimen and one
passing through a liquid whose velocity of sound is known with
sufficient accuracy. The measuring liquid employed is an aqueous
solutiou of ethyl alcohol, which has a low temperature coefficient
of velocity.

constructing wave surfaces that 5 and not 3 different
velocities of wave propagation are possible in certain

of technical qaality glycine, NH 2CH2COOH, Small crystals
were obtained on cooling and two recrystallisations gave
materials sufficiently pure for growing large crystals
which were obtained by 8ooling a saturated solution over
10 hours from 52 to 25 0 at a rate automatic"ally con.-
trolled to give a constant supersaturation. This sufficed
to grow crystils of 360 g weight. The measured density
was 1.68 9/cm'. For physical measurements axes were
designated as follows: the crystals belong to Class 2 with

do not accompany the polarisation. Such a transition, frQm
one enantiomorph to the other, has not been reported before.
The right variant would also have similar transitions.
Both types of transitions are -expected to exist.

TITLE: ~Effect of an Intermediate Layer on the Froquency Character-
istics of Ultrasonic Delay Lines
PERIODICALt Akusticheskiy zhurnal, 1960, Vol. 6, No. 2', pp. 171-179
TEXT: In the present paper, the authors derive general formulas for the
coefficients of piezoelectric conversionPtaking account of the effect
of intermediate fayers for the case of unilateral and symmetric loading
of the converter. Proceeding from the general form of A. A. Kharkevich's
theory of piezoelectric converters (Refs. 1 and 2) the"authors derive
formulas (3) and (4) for.the coefficients of unilateral and symmetric
loading, respectively. The equivalent-circuit diagram of a converter
shown in Fig. 2 in the form of a four-terminal network is used for this
purpose. (4) indicates that the conversion losses at resonance frequency
under symmetric loading are four times higher than under unilateral
loading. An analysis of the formulas derived and calculations of a large

number of frequency characteristics-were carried out by means of
electronic computers for the purpose of deriving a general rule for the
frequency characteristic and the bandwidth of transmission. Next, the
authors state that all combinations of converters, ultrasonic polygons,
and intermediate layers can be reduced to three typical cases. First, A
the authors study intermediate layers of oil, rubber, plastics, and other
materials with low acoustical resistance; secondly, intormediate layers
with an acoustical resistance between that of the sound conductor and
the converter; and thirdly, metallic intermediate layers with higli
acoustical resistance. The method of calculation set up here makes it
possible to explain the shift of the peaks of the frequency character-
istic relative to the resonance frequency of the converter, and to
calculate them for the production of converters and for the technical
planning of delay lines. The authors thank Yu. B. Kobzarev for his help-
ful advice and assistance, as well as T. V. Ryaplova, L. V. Suchkova, and
S. P. Pavchinskaya for their assistance in experiments. There are

Vol. 24, No- 10, PP- 1195-1197
TEXT: The application of the method of nuclear magnetic resonance to the
study of polycrystalline specimens is dealt with. This method served for
examining polycrystalline specimens of Rochelle salt, triglycine sulfate
and potassium ferrocyanide. The tests were conducted within a temperature
range covering the phase transition points of these substances. For an
increase of the signal level, the specimens which had a volume of about
2 cm3, were pressed by applying a pressure of 100 kp/cm-2. The experimen-
tal arrangement is described in Ref. B. The following results were ob-
tained: Rochelle salt - KNaC 4H406*4H2O: at a temperature of +230C
(Fig. 11 1) the second moment exhibits a Jump of 4 oe2. This is in agree-
