ABSTRACT: By means of a cloud chamber with seven lead plates the authori
investigated the nuclear interactions which are caused bY the
particles of wide atmospheric showers. In this context a part-
icle is defined as nuclear-active if it Is creates in the lea!
plates of the cloud chamber a shower satisfying certain con-
ditions specified here. At the beginnine-, the spatial distri-
bution of the nuclear-active particles is investigatad. The
authors determined the current density Yruclear-active
of the nuclear-active particles in a wide, nucle-r-active
shower in different center distances by Using a well-known
formula. A diagram shows the results for wide showers vith

statistical errors it is impossible to describe the exact
form of the spatial distribution of the :auclear-active part-
icles. But the distribution received here is not contradictory
to a distribution of the typ r-n, with the value of n close
to 1. Two main groups of nuclear electron showers can be dis-
tinguished: showers with narrow electron cascades, and those
with no electron cascades of high energy., A characteristic
feature of the first group of showers is the narrow angular
distribution of the particles and the high energy of the neu-
tral Pions which form the beginning of the electron-photon
cascades. The showers of the second group have a wide angular
distribution of the particles and a comparatively low energy
of the neutral pionso Besides these two main groups of
nuclear electron showers two small groupti were found. The
next passage deals with the determination of the energy of
nuolear-active particles by means of the different methods
suited to each of these groups. About one half of the
nuolear-active particles are charged, the rest is neutral.
He can be concluded from this that the nuclear-active com-

beating and containment of the plasma depend strongly on the distribution of the mag-

TITLE: Sound-scattering layers as indicators of internal waves in the ocean
SOURCE: Okeanologiya, v- 59 no. 6, 1965, 1038-lQ42
TOPIC TAGS: acoustic echo, ocean acoustics, biologic ecology, acoustic scattering,
oceanography, sonar, oceanographic expedition
ABSTRACT: During the voyages of,the in the winter-spring seasons
-of 1962-1964 the depth of the-ocean.floor,was measured by an echo sounder; it also
was possible to obtain records of sound-scattering layers. This paper discusses
the.collected data on these layers to determine their relation3hip to internal waves.
..The observations were made in the open ocean, and therefore th,q results differ from
earlier studies made in coastaland shallow waters; the variations of the sound-
scattering layers have greater amplitudes and the layers are at greater depths. It
is shown that data on the distribution of these layers can yield important infonrvA-
tion on the amplitudes of the internal waves and the depths to which they penetrate.
In addition, the results give additional information on the ecology of pelagic
animals populating the ocean. A table gives data on the location, time, amplitudes,
wave lengths and depths of sound-scattering layers whose distribution is related
to internal waves. Orig.,art. has:. 2 figures and 1 table. [JPRS3

ABSTRACT: The author makes use of Grammel's indispensable conditions for the
stability of the permanent rotations of a ponderable solid body having
one fixed point foi the purpose of investigating the st4bility of such
rotations in the specific case when the center of gravity of the body is
located on a principal axis of inertia. For the general case the
sufficient conditions of stability of permanent rotations of a ponderable
solid body were previously given by V. V. Rumya-,.,itsev (RZhMekh,
1956, abstract 8040).

the behavior of two anti-poles using the results of the prededing
paperp and formulates the following theorem: If a heavy rigid body
moves about a stationary point 09 and circular crose-sections of
its central ellipsoid of inertia are not orthogonal with respect to

TEXT: Signorini's concept of the reciprocal pole is verified from
first principles and applied to a system of points having a center
,of gravity G and an instantaneous axis of rotation a., which does
not pass through G. Parameters are establIshed for the relative'po-
sitions of ao, G, and a point A which is the reciprocal pole of ao
the central ellipse of inertia of the system. These parameters
are used to investigate a solid body having a fixed point 0 on its
instantaneous axis of rotati6n. The system of displacement v6ctors
and kinetic moments resolves into the general form of a spiralp the
axJs of which passes through the reciprocal pole of ao relative to
the central ellipse of inertia of the body. In the particular case*

thr-ough the center of gravity G, the vector system becomes a couple

author concludes at all known cases of motion of a so-lid body around'
a static point can be divided into three classes in xvbich the dis-
placement vectors can be resolved into (1) a resultant, (2) a cou-
ple or (3) a spiral. Cases of Lagrange complete kindtic symmetry,
permanent rotation of Vaodziyevskiy-Staude, Hess and of StekJov-
Bobylev belong to thin 1st class, Euler's case to the 2nd clads, and
all others to the 3rd class. There are 2 figures.

PERIODICAL:Tsvetnyye metally, 1960, Nr 6, PP 10-13 (USSR)
ABSTRACTI The process of benefIciation of sillimanite ores from
the above deposits with simultaneous isolation of rutile
was investigated. The beneficiation was carried out
according to two schemes: a) separation of rutile from
the ore in centrifugal separators at the beginning of
the process and b) the separation of rutile during the
process of beneficiation of sillimanite by gravitational
methods using jigs and concentration of the classified
material on tables. The experimental results obtained by
both methods are given in the Table. The scheme (a) was
found to be more suitable. The finally proposed scheme
for preliminary separation of coarse rutile concentrates
and their subsequent treatment (using concentration,
flotation of sulphides, electric and magnetic separation)
are shown in Fig 1 and 2 respectively. Pesulting

ores. The experiments were made with ore containing 0.065% Mo sulfide and
0.016% Mo oxide. Molybdenite was the basic mineral. It was established that
Mp losses during the process of basic flotation occurred mainly because of the
incomplete disclosure of MoS~ grains-in the coarse class (+2 mm) whose yield by
crushing is -,1,20%. The authors show the main possibility of increasing Mo ex-.
traction by 2 - 3% on account of additional flotation.concentration of refined
products-in a separate cycle with separation of 10 - 15% Mo products, suitable

TEXT: To concentrate Cu-Mo ore of the Kiyalykh-Uzen' deposit, a collective
system is used with subsequent Cu- and Mo-selection. To obtain conditional Mo-
concentrates, experiments were carried out with a Mo-product from the factory.
A system is proposed taking into account the mineralogical peculiarities (the
size of free MoS2 is 0.03 - 0.05 mm and of MoS2 in concretion with SiO2 is 0.01 -
0.03 mm), the operational parameters of different minerals, and conditions of
their discovery and separation. The conditions and system developed made it pos-
sible to obtain conditional Cu and Mo concentrates at 90 - 9.2% Cu and 56 - 57%
Mo extraction from their content in the collective concentrate.

TEXT: The author considers the vibration of a liquid w1thin-a cylindric
vessel, which moves horizontally with a constant acceleration., The problem is
solved in linear formulation. Some simplifying assumption's are made: the motion
is considered as two-dimensional, the vertical acceleration of the liquid is
neglected, etc. In this case, the problem is reduced to an equation of the
hyperbolic type with respect to the horizontal shifts of particles of the liquid,
which.are at the free surface. The general solution of this equation is derived.
Reviewer's note: In the introduction, the author considers in detail the COMDlica-
tion of this problem and assumes that his work presents the first step in the
investigation of the simultaneous motion of a body and a liquid. Actually how-

case when the average level of the liquid varies in time. The author considers
only that case, when the average depth depends on the time linearly.

TEXT: The author considers a cylinder with a horizontal axist fil-
ied with a viscous incompressible fluid with a free surfacep and it
is assumed that the center of gravity of the cylinder moves hori-
zontally with a constant acceleration a. Making a series of simpli-
fying assumptions, the author solves the equations of motiol~ of the
system and obtains the expression for the free ourface of the fluid
which is more general than the one obtained by P.I. Gror'kov (Ref.

latter on equating the coefficient of viscosity to zero. There are

TEXT: The author proposes using tensor calculus and lists all the
algebraic and analytical operations used in this worko Then, using
the above relations, she derives general equations of motion of a
rigid body with fluid-filled cavities about a fixed -:)oint without 4_
restricting the shape of the inner cavities and the extent to whichi
they.are filled with fluid. The method of derivation is based on
ihe general theorems of the dynamics of material point systems.
This is followed by the case of abody with cavities completely fil-
led with a viscous fluid; additional boundary conditions are deri-
ved which, together with the Navier-Stokes and continuity equations

energy of the system lead to a simplerp and at the same time more
general expression for N.Ye. Zhukovskiy's theorem on the change in
kinetic energy of the whole mechanical system during 'Lts motion.
The limiting moTiong defined as the motion during which the kinetic:
energy T = const, is considered and the conditions necessary for
this motion to take place are derived. In conclusion, the author

TITLEt Production of Calibrated Ball Bearing Steel
PERIODICAL: Metallurg, 1961, No. 4, pp. 23 - 26
TEXT: At the Zlatoust Metallurgical Plant calibrated. ball bearing WX 9
(ShKh9), UJ X 15 (ShKh15) and WX15cr (ShKhl5SG) steels of 10 - 53 mm size are
produced. For 48 mm shapes, 85 mm square blanks are employed, and 120 mm squares
for shapes of over 48 mm. Prior to rolling the blanks are etched, cleaned with
abrasive disks, and preheated in continuous furnaces up to 1,0800C. During the
rolling process the quality of the rolled stock surface is kaspected. Cooling of
the rods after rolling, down to 900 - 7000C eliminates overannealing of the car-
bide network. Black annealing of ball-bearing steel is made in chamber type fur-
naces with extensible floors and in furnaces with external aechanizatIon. The
sprayers areane-side arranged; pressure and temperature arc-, automatically con-
trolled. Conditions of black annealing in furnaces with extensible floors are:
heating to holding temperature at a rate of 100 per minute; holding at 7600C for
I hour; at 7700C for 2 hours; at 7800C for 4 hours and at 790OC: 4 hours for

ShKhg steel; 6 hours for ShXh15 and 8 hours for SM15BG steel. Stepped anneal-
ing, aseures satisfactory and uniform heating of the metal and good operation 0of
the sprayers. The metal ii cooled at a rate of 400 per hour down to 700-72D C
with Isothermal holding and subsequent cooling to 600-5500C (Figure 1). Prior to
drawing the metal is immersed to remove the sodle from the surface. The remain-
ing scale is eliminated in rotating drums and by etching. The rods ar6 then
coated with a sodium nitrite aqueous solution heated to 60 - 700C for 15 - 20
minutes. Cold drawing is made with I - 2 mm reduction depending on the diameter
of the initial blank. Savings in metaland higher efficiency are obtained by
mechanical pressing of the rods into draw plates (Figure 2). The rod is clamped
in a carriage, whose reciprocating motion is produced by levers which are driven
by a crosshead and pull rods. The use of this device yields savings of metal at-
taining 60 - 70 mm per length of eaah rod. Bright annealing Is made in rectangular
electric cupola furnaces of the OKC-426 (OM426) type using commercial nitrogen
as shielding atmosphere. The furnace operation was unsatisfactory although some
improvements were tried. Therefore it has been decided to replace these fur-
naces by induction furnaces. Actually, bright annealing of calibrated steel is
performed in pipes at 7200C for 12 hours, and with air cooling. About 1 ton of
calibrated rods are placed in the pipes which are sealed at one end. The shielding

atmosphere inside the pipe is produced ' witha mixture of fresh cast-iron chips and
charcoal. After the rods have been placed in the pipes the open ends are.sealed
too. The quality of annealed metal is checked. Exceedingly decarbonized metal is
subjected to repeated oxidizing annealingg at 750 - 7700C with air excess In the
furnace at the expense of negative pressure and by opening tho air slit of the
sprayers. This heat treatment assures the correction of 97% of metal rejected due.
to unsatisfactory decarbonization. The technology described in producing ball
bearing steel yields 92.3% ShXh9 and ShKh15, and 91.3% ShKhl5SG steel out of the
given amount of rolled stock.

Tl=: A unit for the hot drawing of hard-to-deform steels
PERIODICAL: Metallurg, no. 2, 1962, 33 - 35
TEM At the Zlatoust Metallurgical Plant a unit for the hot drawing of
hard-to-deform steels was developed and put..into operation. It consists of a
drawing mill, type I/750M, a tubular furnace to preheat the w1re and a device for
measuring the wire temperature during drawing. The wire is preheated in the
tubular furnace by passage through molten lead and a charcoal layer. The capaqity
of the furnace is 75 kw, feed voltage 380 v, and the amount of lead 2,000 kg. The
lead level remained almost unchanged after the calibration of over 100 tons high-
speed steel; the wear of the draw plates is about 0.01 mm per I ton of wire.
The wire temperature when leaving the'draw plate is controlled by an infrared
photo-electric pyrometer developed by NIIM, being able to measure temperatures
within a range of 200 - 5000C. The pyrometer is combined with an electronic pq-
tentiometer 31111 -120 (EPP-12). The le"t wire diameter during the measurement

is 2 mm. The distance from the sensitive head to the wire surface is 5 - 10 mm.
The device is power-supplied from a 220 V 50 cycle circuit through a ferro-reso-
nance voltage stabilizer. The device operates on the principle of measuring the
intensity of infrared radiation of the. heated metal. Its blDck-ciroult is given.
The draw plate temperature is controlled and regulated by an induction power-fre-
quency heater'which is mounted on the draw-plate holder, in whose body a mano-
metric thermometer.is mounted. The.introduction of the hot drawing method at the
Zlatoust Plant yielded the following resultst,, reduction of heat treatment and
preparatory operations by a factor of 3 -4; reduction of technological produc-
tion time; increase of the drawing-drum efficiency; reduction of,annealing time
by about 35.5 hours per one ton of steel; reliable operation of the unit and the
possibility of using it in other plants. There are 3 figures.

In the cold drawing process of P 18 (R18), P 9 (R9) and 9 X 18
to
(9Kh18) high-alloy, low-ductility grades the wire rods have to be subjected
ntermittent heat treatment.. To eliminate this cumberzome procedure, the Zla-
toustovskiy metallurgicheskiy zavod (Zlatoust Metallurgical Plant) draws these
steels in heated condition. (since 1952). The first method of'heating (by elec-
tric contact) produced sometimes local overheating of the wire, which resulted
in raptures. Therefore, another method was established by which the metal is
heated prior to drawing in a lead bath (5,860 mm long, containing 2 t molt3n
th me
lead, heated by a 75 kw current). The bath temperature is 350 - 370 C, e t-
al is heated to 290 -.33eC, while just before the calibration its temperature
is 300'C. The RIB wire rods are drawn by 34, 62, 76-5 and 81.5%, the 9Kh18 ones
by 66.5% in total. The optimum drawing rates ensuring the required heating of

the metal are given. Prior to the intercalated lead-bath Mating process, the
wire rods are subjected to the conventional heat treatment. The wires produced i
by hot drawing have a bright surface, the same microstructu,.7e as cold-drawn
ones, the aquadag coat applied to the metal surface before It is passed through
the lead bath prevents it from being decarburized and oxidized. The mechanical
characteristics of the hot-drawn steel wires are satisfacto:.y, both grades 6sin-
tain their ductility even at high deformation rates. The new method raised the
output of tlie-drawing equipment by a factor of 2; 'the elimination of intermedi-
kwh/t, while the primary costs for drawing 1
ate annealing processes saves 315
ton of steei'deareased by 177-63 rubles. Accordingto an Editorial Note the
drawback of this method is that it requires much lead and a very good ventila-
tidn to remove the noxious lead vapors. It seems to be preTerable to heat the
wire rods by induction, as introduced in the Zavod Proletariskiy Trup (Proletari-
an W6rk Plant) and.now under investigation at the 'I=. The lead-bath method was
developed in cooperation with S.F. Fetukhov (Deceased), R.I.. Valentova, O.G.
