Morsed ir. molten germanlum, then gradually pulled out of it (at a pulling rate of 60
nm/hr). Thanks to surface tension forces, a thin-walled tube builds up behind the
seed. The temperature conditions are chosen such that the crystallization front is
located slightly (1 mm) above the upper end of the rod. Thus, during V(e pulling,
crystallization begins under conditions where thin-walled tubes about 11 an in diameti
can be grown onto the seed. In the cross section, one single-crystal ain frequent:
predominates over other single-crystal grains by displacing them during growth. In
good specimens, the thickness of the tubes was 0.20*6.3 mm. The length k90-100 mm)

;TRA1NSLATION: The substance of a method for producing art1cles directly from the melt
las proposed by the LSI@Ei@.@]@edagStgjSjal Institute in Gertsen and students of the auth-
or, is presented. This technique was tested under laboratory conditions on materials
,with different thermoi)hysical and mechanical propertieslyn the -solid and liquid state,
h'c*l-r -@'IYC@7S. -hers.
on Al, Cu and t i cast iron and ot. Acco Sing to the proposed technique
it is possible to organize the production of Al and Al alloy parts in the same distinct,
,steps. This technique necessitates extensive changes in the,5ptal processing plant.
iThus, for example, it is advisable to produce parts from Allan'd its alloys at a plant
Iwhich produces Al. It was noted that the above method for producing parts is still in
@the development stage. N. Yudina.

/ABSTRACT: Thermal conditions and process parameters for the continuous casting of
thin-walled products from a melt are given. rour cooling methods are described: 1)
drawing from a melt with the crystal front sliding across water-cooled metal shoes;
:,J' convective cooling in a liquid; 3) convective cooling in a liquid without a buffer
zone; 4) by air-blast or water spraying. For method (1) so much friction results fro@
the ingot-wall interface that wall thicknesses must be maintained above 5 mm. Heat
conduction coefficients varied from 1000 kcal/m2-deg-hr for (1) to 2000-10,000 kcal/
/M2-deg-hr for (4). The temperature was--given as a function. of X--the Vertioal 00OZ-.

TOPIC TAGS: thermal neutron, neutron diffusion, neutron absorption, neutron diatribu-
tion, relaxation process
ABSTRACT: 7his is a surmry of paper No. 105/3727, submitted to the editor and filed
but not published in full. The article deals with diffusion of thermal neutrons from
a stationary source in a medium in which the degree of absorption of neutrons varies
from point to point in accordance with a randoirk law., with a constant diffusion coeffi-
cient. An approxitrAtion using -the second moments of the distribution of the neutrons
i:@ employed. Cases of isotropic (on -the average) and strongly anisotropic media are
considered. An expression is obtained for the rela)-.ation constant of the neutron den-
sity in the medium, in which the homogeneity is violated by meana of localized inclu-
sions.

determined yield of the rare earth fragments was found to be 60 %. The time
required for the radiochemical separation of the rare earth fragments Athout
a carrier was 2.51 hours. The addition of Fe(III) before the precipitation of
Ce(103) reduced the losses. The possibility of using the extraction of iron
diethylcarbamate into ether from 0.1 n HC1 for removal of the iron in thelast
stages was investigated and vras found to be unsuitable, since products of the
thermal decomposition of diethy1dithiocarbamate remained behind. The electro-
phoretic separation of the rare earth sum fragments and the appa-];atus used for
the procedure shown in Figure 1 are described. The apparatus is being recon-
structed at present in order to decrease the time of the separation of the sum

(26o-28o v (20-30 v/cm) is switched on. After
2-5 aiinute3 the concentvation gradient is established,
and aftev 2-3 minutes the elements are separated and
concentrated. Position of the zones Is found by
direct measurement of radioactivity of the paper
strip or by autoradiographic method (autoradiographs
are given). Identification of the elements is done
by measuring the maximum R -radiation or according
to the half life periods . Conditions of the experi
ments and the results are shown in Tables 1 and 2.
The following conclusions were made: MiXtUVeS
Sr 90 + Ygo ; Sr go + Y90 + Ce 1411 ; and Ce 144 + La 14o
can be separated by the above inethodusing
complexon III or citric acid, in 5 minutes. The

TITLE: Novel method for the making of parts (sheets, rods, tubes of various
profiles) directly from a melt.
SOURCE: Avtomatizatsiya protessov mashinostroyeniya. t. 2: Goryachaya
obrabotka metallov. Moscow, Izd-vo AN SSSR, 1962, 26-29.
TEXT: The paper provides details on a fundamentally novel method for the
making of parts out of metals, alloys, intermetallic compounds, semiconductors,
salts, organic compounds, plastics, etc., which the author and his associates had
initiated in 1938 and first disclosed in ZhTF, v. 229, 1959, 381 and 394; Vestnik
mashinostroyeniya, no. 11, 1959; and Akad. n. SSSR, Izv., Otd. tekhn. nauk. Metallur-
giya i toplivo, no. 5, 1959. The participation of V. N. Dyn'kov, A. L. Shakh-Bydagov,
B. M. Golltsman, and A. V. Donskoy, in various stages of this work is. acknowledged.
The novel principle of shaping material consists in establishing the required form,
or its basic element, in the liquid state by capillary, kinetic, or other effects.
"Freezing" of the shape thus established creates the desired solid object in speci-
fied conditions of crystallization. The shaping device consists of a "float" that is
set up on the horizontal surface of the molten metal. The float is a horizontal plate
-oninteracting material with a suitably shaped vertical slot, surmounted by a

cooling installation. A "primer" or "catcher" is lowered through the slot into the
liquid metal and is then lifted, drawing liquid metal with it through capillary and
me tallos tatic -pre s sure action. The metal reaches a zone of low temperatures and
congeals into the given shape (sheet, rod, tube) establisheo by the shape of the slot,
the rate of pulling, the cooling history, etc. Thicknesses from tenths of mm to tens
of cm can be drawn, with preference for thinner shapes; thicker shapes require
lower pulling rates. NOTE: The slot shape alone does not determine the final
dimensions of the shape of the product; the slot is not a die I The crystallization
takes place at the top of a shallow liquid column that is held together by capillary
forces and, hence, is thinner than the slot. Parts with a*longitudinally varying
section and curvilinear parts can be made. The crystalline structure is controllable.
The rate of pulling is essentially a function of the heat-transfer process. Equip-
ment required: (1) Continuous smelting furnace; (2) continuous drawing mechanism;
(3) shaping equipment, consisting of float, cooler, and moving equipment;
(4) product- removing mechanism; and (5) inspection and control instruments. The
last-cited reference describes the author's and B. M. Golltsman's lab setup (at the
Leningrad State Pedagogic Institute - LGPI) for the making of "endless" strip of Al
and Al alloys, up to 120 mm wide and 0.5 to 3 mm thick. The pulling rate with air
cooling attained 25 m1sec. The strip has a high-grade surface, and its-mechanical
properties are equivalent to those of rolled and annealed Al strip. A cross-section
shows the graphite -crucible smelting furnace, the slotted "float" plate, and the

'IMTI-LIXT: In this article, the author discusses the calculation
of uncut beams in an elastic-plastic stage with a
constant load. The aim of the calculation is the ob-
taining of an elastic-plastic epure of the bending
moments. The solution is obtained by the method of
consecutive approximation with the aid of the grapho-
analytic method Z"-Ref. 1_7 by which the compiling and
the solution of the system of equations becomes super-
fluous. It is to be noted, that the solution of this
problem according to a method of strain equalization

elastic-plastic epure permits control of the degree
of approximation, as well as the use of various methods
of speeding up the convergence and the intuition of
the calculator. The presented formulae make the pro-
cess of integration during the computation unnecessary
in all possible instances. The method described may be
extended to the calculation of uncut beams in the case
of material with reinforcement as well as in the case
of a movable loading. There are 4 diagrams (epures),

TEXT: In this purely mathematical work the author gives approximate for-
mulas, arrived at by using the variation method, for the calculation of high
beams on a normal load distributed alcng the upper and lower edges with the lat-
eral edges being free from load. These formulas (1, 2, 3) are said to be ade-
quate for calculating isotropic high beams having a rectangular cross section.
They do not allow for volumetric forces. They are based an equations of the t1L_
ory of elasticity for plane problems. Coefficients are calculated by formulas
(4, 5, 6, 7). Two examples of how to use the formulas are given. T'he solutions
satisfy the equations of equilibrium and the boundary exactly, and the condition
of conjointness of strains approximately. The solution indicates the relative
minimum of the potential energy of the beam's deformation. The formulas aresaid

are stated to show that the process will be convergent for any number of
knots. Method of simulating boundtry conditions is described. The si-
mulating lattice has been tested at the Computer Center of AS UkrSSR.

ABSTRACT: The authors describe in detail the new Tu-114 four-
turboprop passenger monoplane constructed under the supervision
of Academician Andrey Nikolayevich Tupolev. The Tu-114 represents
the result of a prolonged effort to design and construct a plane
capable of carrying 170-180 passengers almost as economically as
a railroad train. A mock-up was discussed and revised by
specialists from many fields,in--luding doctors. Each of the 4
turboprop engine 's has almost twice the power of any non-Soviet
turboprop engine. They were built b7 a group led by N.D. Kuznetsov,
Hero of Socialist Labor. The Tu-114 is manned by a crew of five.
The test flight was made by Aleksey Petrovich Yakimov, his
assistant Yuriy Timofeyevich Alasheydv; flight engineer Leonid
Alekseyevich Zaboluyev, air navigator Konstantin Ivanovich
Malkhasyan, and Nikolay Fedorovilch Mayorov. There are 21

TEXT-t,Y The fluctuations observed in the braking of the Soviet satel-
lite by the upper layers of the earth's atmosphere have led scientists to
conclude that this braking depends directly on thdilgolar activity. The
F-y and month to
density of the atmosphere was found to vary from day to a
month by 1.5 times at a height of 200-250 km and by 3 times at 700 km. In
addition to these irregularities, the atmosphere undergoes a periodic change
in atmospheric density (28-day cycle). This is attributed to a solar ori-
gin, since the sun rotates roughly every 28 days. Streams of charged par-
ticles issue from the sun, and the earth passes through these at intervals
of 27-28 days. Collision with the corpuscles affects the thermodynamic
parameters ef the earth's atmospheric envelope. V111,

PERIODICAL: Kryllya rodiny, 1960, No. 9, P. 17
TEXT: This is a reply to a reader on the difference between a turboventi-
lyatornyy dvigatell (turboprop engine), such as used on Ty -114 (Tu-114), WA -18
(il-i8), AH -io (An-10) airplanes and the Mvi -6 (Mi-6) helicopter. The turbo-
ventilator engine is a turbo-air feed jet engine, also often referred to as a
dvukhkonturnyy dvigatel' (double-contour engine). Thus far, it has not been pos-
sible to design an air-screw of normal type whose efficiency would not drop at
flight speeds of 800 km/h and more, because of the appearance of the wave drag
on the air-screw tips. Conversely, it was found that an engine incorporating a
gas turbine, a compressor and a small multiblade air-screw (called ventilator)
encased in a jacket, is much more efficient at the above-mentioned speeds. The
ventilator is driven by a part of the turbine power, compresses the air within
a sealed jacket around the engine and throws it out through an annular gap beet.-
ween the nozzle and the jacket, thus producing a forward thrust. This engine is

TEXT., The article deals with engineering, biological and psycholo-
gical problems which must be solved to secure safety in manned space
flights. First of all, scientists will have to create conditions
during the launching of a space vehicle which would keep the g-load
and its duration within tolerable limits. It has been experimentally
proved that man can best withstand g-loads when placed flat (face
upward or downward) and perpendicularly to the g-forces in order to
effect the least strain on the entire circulatory.system. When the
required velocity is attained, the effect of the g-forces is dis-
continued and replaced by complete weightlessness. The astronaut
can easily learn to move inside the cabin by using grips fitted to
the cabin walls or other devices. Also.) artificial gravity can be

produced by using boots with magnetic soles, or by rotating the
cabin or the entire vehicle around its longitudinal axis. The
composition of the atmosphere inside the cabin can be maintained
constant by highly active chemical compounds releasing oxygen and
absorbing carbon dioxide and excess vapors. An effective protection
of the astronaut against cosmic radiation is one of the most impor-
tant problems to be solved. While this radiation can be avoided on
comparatively short space flights, such as to the moon, it will
inevitably be encountered during journeys to other planets. Another
complicated and not yet satisfactorily solved problem is that of
reent-ry. The task is to gradually decelerate the space vehicle by
retroengines, or a series of short "dips" into the atmosphere, or
by -some other methods. Prolonged weightlessness,*unusual environs
without the accustomed night-and-day cycle, increase not only the
physical but also the psychological strain on man. The opinion was
voiced abroad that man may lose his mind under such conditions.
However, the example of four Soviet soldiers who spent 49 days on
the Pacific ocean under extreme nervous strain without any con-

sequences to their mental condition shows that there are many
individuals in the USSR who will qualify for space travel. A pros-
pective astronaut must be an energetic individual with well-develop-
ed physical and mental capabilities, able to operate the complex
board controls and instruments, and capable of quick reactions even
in the most unexpected situations which may occur during space
travel. There is 1 figure.

TITLE: The Redox Potentials of Xanthogenates (Okislitellno-vosetano-

PERIODICAL: Nauchnyye doklady vysshey shkoly. Khimiya i khimicheskaya
tekhnologiya, 1959, Ur 2, PP 277-279 (USSR)
ABSTRACT: In the present investigation the same method was used that
the authors employed for determining the redox potentials
of dithiopho3phates (Ref 1). The calculation of the potentials
of the reaction (1) 2 ROCSS' - 2e = (ROCSS)2 was carried out
According to the graphical method described in reference 1.
The redox potentials of methyl-, ethyl-, n-propyl-, n-butyl-,
n-amyl-, n-hexyl-, n--heptyl-., n-octyl--, n-nonyl- and n-decyl
xanthogenate are shown by figure 1 and listed in table 1.
The potential increases as a result of -the decreasing solu-
bility of dixanthogenide with growing carbon chain. The sec-
ond author found in an earlier investigation (Ref 10) that
the solubility of the members of a homologous chain is reduced
by 1/4.25 in the case of an elongation of the chain by a
Card 1/2 CH 2-member. This corresponds to 1/(4.25)2 = 1/18 in the case

The Redox Potentials of Xanthogenates SOV/156-59-2-14/48
of the disulphide with 2 radicals. This is in agreement with
the increase of the potentials for the higher xanthogenates
(over C.), while in the case of the low ones the values of
measurement are too low by 5 -- 15 mv as compared to calculation.
This may be explained by the partial irreversibility of the
reaction (1) with low xanthogenates on the platinum electrode.
The reversibility of reaction (1) is to be investigated in
a later paper. There are 1 figure, 1 table, and 10 references,
5 of which are Soviet, and 1 Rumanian.

ABSTRACT: Organic sulph.-hydryl reagents@ such as xanihogenates, di-
thiophosphates, mercaptanes, dithiocarbamatbsq etc., are used
to an ever-increasing extent in industry for flotations,
in hydrometallurgy, in analytical chemistry, etc@ For thermo--
dynamic balance calculations in connection with ihe above
reagents, it is necessary to know tha redox potsntial (RP)
of these compcunds@ but ihe publications hardly contain any
of the desired data. The present paper is; for this reason
devoted to the study of the (RP) of the ions of dialkyldi-
thiophosphates. The firmness of the chemical bond between the
two disulphide molecules is determined by the density of
the electron cloud between themv i.e. the character of the
central core of the group and the struotUre of the apolar
part. The synthesis of dithiophosphoric acids was carried
Card 1/3 out by means of the reaction of alcohols with phosphorus
