that the electron ion currents emerging from the plasma are equal to the current en-
tering the plasma. The observation of outflowing currents has shown that for suffi-
ciently long plasma-beam interaction length, the current from the end of the plasma
consisted solely of ions. The investigation of the frequency distribution of the ex-
cited oscillations shows that the ion current arises in situations favoring the produe-
tion of instabilities. The most favorable conditions for generating beams of ions
with energies up to 1 kev are given, The study of excitation frequency change with
,electron temperature and type of gas used shows that the low frequency oscillations
generated in the experiment were near the ion-acoustic frequencies. Further study of
the generation of low frequencies is needed. Orig. art. has: 6 figures, 1 table.

TITLE: Reaction of free radicals with unsymmetric organic mercury
compounds
PERIODICAL: Akademiya nauk SSSR. Izvestiya. Otdeleniye khimicheskikh
nauk, no. 9y 1961, 1582-1589
TEXT: The authors studied the interaction of free radicals with a
number of asymmetric saturated organo-mercury compounds with a view to
elucidating the order in which radicals are split off by a radical reagent
and establishing a sequence of radicals. The benzoyl peroxide initiated
reaction of carbon tetrachloride with saturated organo-mercury COMDOunds.
discovered by A. Ye. "Rorisov (Ref. 8; Izv. AN SSSR. Otd. khim. no 1951,
524) was used as example for this study. The mercury compounds used were
of the type RHgR' listed in the table. They were prepared either
(compounds 11, 12, 13, and 14) by the method developed by R. Kh.
Freydlina, K. A. Kocheshkov, and A. No Nesmeyanov (Ref. 9: Zh. obahch.

khimii, 5., 1171 (1935)) or by means of the Grignard reaction. It was
observed that in the reaction RHgRt + CC1 4---iPRHgCl + RICCl 3 the free
radical CCl* always combines in higher yield with a radical further left
3
in the following sequence than with one further right:
2,4,6-(CH 3 )3C6H21 a-C 10H 7' p-CH 3C6 H4' o-CH 3C6H4' m-CH3C6H4' C6H5' C2 H5'
C4H91 C 6 H5CH2' C011. If the radicals are further apart in this sequence,
the reaction is frequently nearly quantitative. For a chain reaction with
radical mechanism the order found shows a certain similarity to the
sequence set up by M. S. Kharasch (J. Amer. Chem. Soc., -~-8, 3130 (1926);
ibid., 5A, 674 (1932)) for the heterolytic reaction. The course of the
chain reaction may be represented as follows:
(C6 H5COO)2 --->C6H; + C6H5COO* + C02
C 6H; + Ccl 4 ---~ C6H 5Cl + CCI;
CCIj + RHgR' ---> RHg' + R10013
RHg* + CU 4 -,>RHgCl + CC1 etc.

The course of the reaction is therefore determined by

since in the further course of the reaction the RHg radical only
participates the regeneration of the chloromethyl radical. The sequence
established on the basis of decreasing proton affinity of the radicals
corresponds to one based on decreasing affinity of the radicals towards
the free radical CCI 3* There are 1 table and 14 references: 5 Soviet-

TEM The investigation started in Ref. 1 (Zh. obshch. khimii ~2 (in print)
(1962)) was continued as follows: ~-methyl tetramethylene diboric acid was
synthesized on the base of diborane and isoprene. All the reactions were
performed in pure nitrogen atmosphere. Diborane and isoprene readily react
in tetrahydrofuran at room temperature. The product is bis-1,4-0-boro-2-
methyl cyclopentyl)-2-methyl butane C 15H3OB2 (1) (boiling point 880C
(0.2 mm, Hg); yield 64.7%). By heating (I) with boro trichloride (2000C,
20 hr) and by distillation, 1,4-bis-(dichloro boro)-2-methyl butane
C5H10B2Cl4 (11) was obtained (boiling point 360C (0-7 mm Hg); yield 80%).
The hydrolysis of (II) yielded ~-methyl tetramethylene diboric acid

TITLE: Method of determining the strength properties of metals at
high temperatures
PERIODICAL: Zavodskaya laboratoriya, v. 27, no. 8- 1961. 1018 - 1021
TEXT: The authors developed methods of testing the elongation of metal
specimens (tungsten) at high temperatures and deformation rates When the
deformation was accelerated from 555 to 3500 %/sec, the plastic strain of
tungsten specimens was found to remain constant for the same temperature
and degree of deformation. Besides, the plastic strain of specimens heated
to 1500 0C was shown to rise by 25 - 30 % at a rate of 3500 %/see.. as
compared with 555 %/sec. The effect of the deformation rate on the deform-
ation resistance is not yet known for many alloys and metals, including
tungsten. Tungsten differs from most metals and alloys by its friability.
Its initial structure, grains with equally long axes, changes in defortration
since the grains are lengthened. The resulting texture leads to higher
plasticity and strength. This texture disappears, however. on heating

above recrystallization temperature, and the metal becomes friable again.
The authors describe their quick tensile tests of tungsten specimens (also
applicable to other metals) at over 10000C. Such tests Lire rendered
difficult by the necessity of holders resisting such temperatures. If the
holders are to be kept distant from the heating zone, long specimens would
be required. 71ater-cooled holders create a high 'Llemperature gradient along
the specimen. In the authors' methods. the maximum test temperature is not
limited by the resistance of holderslutlythe furnace construction The
protective gas produced by heating prevents oxidation of specimens, Tests
were made on a chain draw bench with four slide speeds to simulate real
conditions as closely as possible (deformation rate of tungsten in rolling
is 500 - 1500 %/sec). The authors used 0.222 and 1-4 m/sec, At a
calculated specimen length of 40 mm, this corresponds to deformution rtiteB
of 555 and 3500 ~~/sec. Specimens were produced from rods by rotary
forging at 1400 - 110000, and contained 0.001 ~, Ni; 0.01 % SiO2; 0.005 % CaQ.
and 0.029~c Mo; the rest was W. The holders were made of hardened Y707)
steel. Fig. 2 shows a diagram of the apparatus. The specimen 1 in a quartz
tube 2 was heated in an electric circular furnace 3 witil a silicon carbide

heating. The Projection 4 prevented the specimen from gliding in the tube.
The platinum - platinum - rhodium thermocouple 5 indicated the specimen
temperature. After reaching the temperature requi.red, the quartz tube in
the furnace was turned through 1800, arid the specimen dropped from the tube
through the funnel 6 into holder 7. The slide 8 was quickly coupled to the
moving chain 9, and the specimen was ruptured. The specimen temperature was
recorded during its stay in the holders on an Oscilloscope by i,Deans of the
optical head 10 (consisting of focusing lens and photoresistor with small
time constant). The optical head was calibrated before the test, and a
calibration diagram plotted in the coordinates "deviation cf the ray in
mm - temperature in 0V. The sine curve of thea-c vol taire of a 3P- IO(ZG-10)
sound generator was simultaneously recorded on the ci.art The stress was
recorded by the measuring box 11 fed from an 9T-4(ET-4') fuuz-channel
amplifier. The measuring box was calibrated an the ben,~h by means of a
spring dynamometer with pointer. The oscillogramB were evaluated as fol-
lows: 1) The point corresponding to the beginning plastic deformation was
determined on the oscillograms considering the known slide spoed and the
sine curve recorded (see above). 2) The specimen diameter was measured
after rupture in the area of steady necking. The specimen volu:11e was
divided by the area corresponding to the diameter measured.. Thus, the

authors determined the length of the calculated part at. rhe moment of
maximum uniform deformation. 3) From the beginning of pl.ast--ic deformation,
the authors calculated, from the number of periods, the Lime during which
the absolute elongation of the specimen proceeded which corresponded to
maximum uniform deformation of the specimen, The stresse3 in this section
were calculated by dividing the load at the given instant by the area of
the specimen cross section at the same instant (thi.9 area -was de,.-armined
from the condition of constancy of the specimen volume during dc"ormation).
4) In the section corresponding to localized deformation, the cross-section-
al area was determined graphically. The authors explain their results,
mentioned at the beginning, as followsi At 12000C and 1350'.1 C, no effect of
the deformation rate on the plastic strain was found. At these temperatums,
the rate of recrystallization of specimens with the corresronding content
of admixtures is much lower than the deformation rate.. Therefore, the
strength is not changed by recrystallization on transition from one rate to
another. At 15000C, however, recrystallization becomes much more intensive.
Since recrystallization reduces the plastic strain, the oharacter of the
curve deDends on the interrelation between the deformation rate creating
a strengtb-inereasing tungsten texture and the recrystallization rate at

ABSTRACT: An investigation of vibraiion in pipelines containing a flowing ideal fluid4i
is described. The damping effect of the Coriolis forces produced during pipeline --I
vibration is discussed. The friction forces within the fluid as well as friction of
the fluid against the pipe's walls were not considered in the investigation. rhe
following conclusions were reached: 2) A pipeline with angle bracle'ets containing a
flowing fluid is a dissipating system. In relation to vibration disturbances, it is
more stable than a pipeline with both ends attached. b) The vibration damping is
caused by the effect of Coriolis forces. When the fluid flow is increased, the
damping increases to such an extent that the natural vibrations of the system become
impossible, and the system is only capable of aperiodic motion. c) The logorithmic i_

TOPIC TAGS: plate, antsotropic plate, uniform load, sandwich plate, plate oscillation,
movable load, continuously distributed load, elastic body, orthotropic plate
ABSTRACT: The problem of the oscillations of elastic bodies as a mass flow moves
over their surface Is encountered in the study of various radiator,, systems and also when
considering' the oscillations of certain other bodies having a cooling liquid between the
walls. In the present article, the author has investigated the free oscillations of ortho-
tropic plates supporting a mass flow, uniformly distributed over the surface. Frictional
forces between 'the flow and the plate are assumed to be absent. The flow trajectory re-
peats the fie2donal form of the plate oscillations. Des.0-wise, this arrangement may be
realized by passing a flow or stream of liquid between the layers of a sandwich plate with a
corrugated fillor. In a certain frequency range, the sandwich plate may be replaced by a

single-layer orthotropic plate, equivalent to It in the sense of flexional rigidity; however,
the problems involved In a reduction of this sort are not taken up in the present paper.
This article represents an extension of the well-known problem of free oscillations of
pipelines to the oscillations of plates. On the basis of his investigations, the author has
concluded that: 1. The effect of the mass flow on the dimensionless eigenfrequdncles of
the plate is determined by two parameters ii and k. Since k depends on the ratio of the
masses of the liquid and plate (i.e., is an invariable factor for a given structural design),
all further conclusions must pertain only to the variation of the parameter p. 2. The
eigenfrequency of plates which do not have free edges In a direction transverse to the flow
decreases as the parameterju increases. 'With respect to plates with a free edge it
should be noted that experiments studying the free oscillations of pipelines have establish&.
that the eigenfrequenotes of cantilever pipelines do not change (within the accuracy limits
of the experiment) when the velocity of the liquid flowing In them is increased, despite the'
theoretically predicted fall In eigenfrequency. . Thus, for plates also (that is, those
having a free edge), no perceptible change in elgenfrequency as the flow rate is increased
should be expected. In any ev t, the author admits that this conclusion requires experi-
mental confirmation.. 8. 7he mass flow exerts. a damping action on the oscillations of

plates having a free edge in a direction transverse to the flow. The damping value in-
creases with the parameter p. Having attained a certain value of A, the damping increases
to such a degree that free oscillations become impossible (the frequency becomes zero). As.
~
I experiments with cantilever-fixed pipelines have demonstrated, the transition from periodic 1
movement of the tube to aperiodic (movement at zero frequenoy), as the flow rate Is increased
occurs while the eigenfrequency of the system oscillations remains unchanged. The author
notes that an analogous phenomenon occurs in plates. If there is no free edge in the plate,
there is no damping of the oscillations` 4. A constant mass flo-kcan result in a plate
stability loss. Using the terminology of V. V. Bolatin (V. V. Bolotin. Nekonservativny*ye

versitet (Leningrad University), which is an abbreviated and modified
variant of ALGOL-60,,',Is described. -,The laxiguage differs from ALGOL
in~that the program as a whole cohstitutes one block and there are
no"descriptions of types; a separate class of identifiers 'is used
for each class. The operators (particularly the procedure operators):
and the description of the procedures are simplified and standardized.
The input lanq~uage itself and the operating principles of the pro-
graNiming program are described in detail and the algorithm for solv
ing a system of linear algebraic equations of 50th order by the
Gauss method, with choice of the principal element, is used as an
example. Orig. art. has: 28 formulas.

TITLE: The Energy Spectrum of the Fragments of the Photofission of

PERIODICAL: Zhurnal eksperimentallnoy i teoreticheskoy fiziki, 1959,

ABSTRACT: In the present paper the energy spectrum mentioned in the
title is determined at a maximum energy of 12.5 Me-v of the
betatron r-radiation. The apparatus used for measuring the
kinetic energy of the fragments of photofission consisted of
a differential pulse-ionization chamber, an amplifier channel,
and an electron pulse osoillograph with photorecording. The
axis of the ionization chamber in operational position formed
an angle of 150 with the axis of the beam. A diagram shows the
energy spectrum of the fragments of the photofission of
U238 at a maximum energy of 12.5 Mev of betatron bremsstrahlung.
By means of the same apparatus and on the same preparation
also the energy distribution of the fragments of the fission of
Card 1/3

The Energy Spectrum of the Fragments of thq SOV/56-36-1-46/62
Photofission of U238
U235 by slow neutrons was determined. Als-, th.-'Le distribution
is shown by the aforementioned diagram. The spectrum of the
photofission fragments has the most probable energies
55-1 + 1 and (86.9 � 1) Mev for th,~ groupfi of heavy and light
fragm-ents. if th* absorption in the layer of this preparation
is taken into account, these two values inorease by about
5 Mev. Tho two spectra differ mainly by the ratio between the
height of the "trough" between the two maxima and the height
of the peak of-the light fragments. In the spectrum of
phot-ofission it is 0.60, and ir. the spectrum of spontaneous
fission it is 0-3'11. This differencs may be dua to the stronger
excitation of the nucleus J.n pho-~Iofi-ssion and also to the
superposition of fluctuations of th~? compensated
- background. In spite of the considerable excitation energy,
no essential increase of the most probable. energies of fragments
and of the kinetic energy in photofission compared to
spontaneous fission was observed. The peaks of the photofission
spectrum are somewhat more close to one another than the
Card 2/3 corresponding peaks of the spe.-,t--'IM of spontaneous fission.

TEXT; There was worked out a technique for producing thin free con-
taining uranium or thorium by cathode spraying a cellulose nitrate backing with
its subsequent dissolution. More than 20 films were prepared, each w:Lth surface
density 0-.1-0.2 mg/cm2 and working area 60 cm2. The uranium films contained ' '70%
U308, and the thorJum films contained 40% thorium and ThO2. Comparison of 0(_..

that impurities (organic matter and moisture) are distributed throughout. fIlm
