ABSTRACT: The paper presents a system of control of various synchrocyclotron operat-
ling conditions. A phototransducer, having an optico-mechanical connection with a high
ifrequency generator furnishes square pul;es of positive polarity. These pulses are us-
ied for the regulation of the generator and for synchronizing the operating auxiliary
apparatus with the accelerator. A flow chart of this operation is shown. In the can-
tinuous mode of operation, the capture and acceleration of the particles occurs in eacl
~period of modulation. The synchronization pulses, coincident with the front of the
I
lphototransducer pulses, are directed into two channels. In the first of these, the ac-
ituating pulses are formed; these pulses move into the exit tube with or without time
delay and then into the operator of the high frequency generator. In the second chan-

nel, the cut-off pulses are formed; these pulses move into the operator with a time de
lay, approximately equal to half the period of modulation. In the single mode, accele
ration of the particles occurs with the frequency of the starting pulses. The synchro
nization pulse, before entering the actuating pulse channel, must go through a coinci-
dence circuit. After leaving the coincidence circuit the pulse returns the trigger
to the initial condition. Other modes of operation of this system include the single
mode with damping, accumulation, increase of pulse width of beam, and operation of an
ionic source with the pulse method. Lost time due to shutdown using this control
scheme did.not exceed 0.1% of the operating time of the accelerator. The authors

struction of the apparatus. Orig. art. hasi 3 figures.

ABSTRACT: A description is given of the effects of an electrostatic field in the
central region in the synch rocyclotron of the Joint Institute of Nuclear Research
upon the accelerated proton current. As a result of theoretical and experimental
research, the chosen aperture of the focusing electrode is equal to the aperture of
the dee. In view of the need for a stable installation for long periods of work,
30-mm gaps were established between the screens and the electrodes and a 170-mm

distance was established between the dee and the electrodes. In such conditions the
maximum current magnitude attained is Ub = 13 kilovolts. As a result of the
increase of focusing forces in the central region of the accelerator, the beam curred
on the finite radius increased from 1. 1-1. 2 to 2. 1-2. 3 , #A In conclusion, the
authors thank senior technicians V_ L Ivanov and Yu. V. Maksimo for the produc-
tion of the 30-kv rectifier; designer 1. Kb. Nozdrin and K. A. Baycher, director
of the machine shops of the Laboratory of Nuclear Problems, for their efforts in the

ABSTRACT: A study was made of the critical time in loading a closed cylindrical
shell by aiial compression combined with external pressure, utilizing linear Initial
physical relationships between elongation and displacement and the components of the
hereditary, forces with one creep center. The above deformations were expressed
nonlinearly in terms of the initial deviation from the regular shape in the normal
direction and in the d1rection of the displacement of the mean point of the surface
in axial and radial directions, with retention of second-order terms. A solution

was obtained bi an approximation method based on the Hamilton-Ostrogradskiy
variation principle. Buckling in a short, thin, conical shell under axial com-
pression was studied by an analogous method, using the corresponding equations
which determine the stress functions in the preceding problem. M, I. Rozovskiy

authors set forth in the article the observations they have
made and submit suggestions tending to improve the present
order of enrollment.
They emphasize that among the students there are persons
who have no particular likine, or are not qualified for the
speciality chosen. The first author, therefore, suggests
that discussions be arranged with the prospective students
in a-4er to find out the views of each one on his chosen
speciality.
He is satisfied that the enrollment regulations of 1957

TITLE: Experimental Determination of the Yielding in the
Compression of Flanges Under the Action of Bolt Tightening
Forces
PERIODICAL: Vestnik mashinostroyeniya, 1959, Nr 6, pp 25-27 (USSR)
ABSTRACT: Tests were carried out with specimens simulating flanges
bolted together made of transparent plastic (TUNKKhP
530-42). M18 size bolts were used in the tests. The
characteristic quantity was considered to be the ratio
of bolt diameter to the combined thickness of the speci-
mens. The thicknesses tested range between I and 6
diameters. The outside diameters of the specimens varied
between 32 and 100 mm. A progressively increasing
compression load up to 2 500 kg was applied, the material
remaining in the elastic range. The modulus of el asticity
of the plastic was found to be about 24 000 kg/cm .
Curves of compression against outside flange diameter are
shown (Figure 1). In all cases, the compression diminishes
rapidly and stabilises beyond a certain diameter. This
Cardl/2 final compression occurs beyond about 40 mm dia.meter at a

thickness of I bolt diameter and be,ond about 70 mm
diameter at a thickness of 4 bolt d:ameters. The maximum
compression is plotted against the 'hickness/dianieter
ratio and flattens out after about - diameters. The shape
of the curve agrees closely with th analytical formula
obtained as a solution of the probl -m of pressing a round
punch into an elastic seml-space. .. practical formula is
suggested for engineering materials relating the com-
pression as a percentage of its valte at infinite thick-
ness to the thickness/diameter rati ). These recommendations
are at variance with existing formtLae.
There are 3 figures, 1 table and 3 ioviet references.

TEXT: The author presents the description and results from an experimental
determination of the magnitude of axial strain of the compressed components in a
stressed bolted joint (determination of ., the yielding magnitude of these compo-
nents). Parts of different thicknesses were made of organic glass (the polymer of
methyl ether of methacrylic acid, ultimate compression strength about 1,000 kg/cm2,
modulus of elasticity 19,000 - 28,000 kg/cm2, Brinell 0hardness 14-1u, Poisson ratio
about 0.3), The experiments were conducted at 2G + ' C. The joint was made with
bolts M 18. It is pointed out that the thesis on the determination of the volume
of the parts jointed from the"cones of effect" was not substantiated by the tests.
A formula of yielding is proposed which was obtained on the basis of the investi-

TITLII: Bridge phase-shifter with a shift up to 1800
PERIODICAL: Radiotekhnika, v. 18, no. 1, 1963, 72-77
TOM The authors describe a bridge phase-shifter which
makes it possible to vary continuously the phase of its output volt-
age from 0 to 1800. The bridge consists of two fixed impedances and
of two reactances shunted by a potentiometer the slider of which,
connected to the junction of the two reactances, forms the hot term-
inal of the output, so that each reactance may be alternately reduced
to zero. The design formulas and the circuit diagram of a practical
phase shifter with two pentodes and one double-triode is given. With
suitable components the device has a linear phase characteristic and
an accuracy of about 176. A special compensating device is introduced
in order to improve the stability of the modulus of the transfer
coefficient to within approx. 0.15 dB. There are 7 figures.

ABSTRACT: A study is made of several methods for the solution of the problem
of the simultaneous management of several petroliferous contours in a
homogeneous horizontal layer with ~onstarit capa,,itv. It is assumed
that a certain number of finite, singly connected sectors exists in the
layer, each of which is saturated with a liquid ha~)ng a viscosity PH
(petroleum), while outside of these sectors the layer is saturated with
another liquid (water) having a viscosity )AB . Under the action of a
number of injection and operating wells, located on the layer according
to a certain pattern, the contour of each sector is displaced. It is
Card I Z necessary to find the debits (withdrawal rates) of the operating wells

Orig:Lnal P,~!r~-odical: Izv. Kievsk. politekhn. in-ta., 1955, 18, 31-41
Abstract: The temperature dependence of the thermal emf of a thermocouple consisting
of a def ormed and annealed specimen of the same metal was investigated. Specimens of
copper, alumirum, ircm, and steel, were studied. The singular points on the clwve cf
emf vs temperatu--e were Dbserved. The temperature at which the maxinnim value of the
thermal emf was observed is the crystallization temperature. The latter depends an
the degree of relative defcrmation, and also on the value of the applied load. For
copper at relative deformations of 41, 54, 60 and 80%, the recrystallization tempera-
ture is 300p 275, 265~ and 2000 respectively. For the same relative deformation, the
external load raises the thermal emf and reduces the recrystallization temperature.
The micro-hardmess and the coefficient of thermal emf were studied for copper and

Abstract: iron specimens. A linear relationship was established between these
quantities. Conclusions: (1) hardening of plastically-deformed metals is due to
the distortion of the lattice and to the change in the energy spectrum of the col-
lectivized electrons; (2) the coefficient of thermal emf can serve as a character-
iBtic of the harcleningj (3) the recrystallizatiam temperature of hardened metals

ABSTRACT: V. S. Ivanova (3) established by high speed filming
that the plastic deformation at the flow surface
develops suddenly and that thereby each deformed
element of the volume has a I-sidual deformation
equalling the critical ont. L, an earlier paper (4)
the author showed that haidening and the coefficient
of thermo e.m.f. are linearly inter-related and that
the softening, being the inverse process, can be
determined from the change in the e.m.f. value.
Experimental investigation of the softening of
plastically deformed metal by measuring the thermo
e.m.f. and the microhardness was effected on low
carbon steel (0-03 C), pure aluminium and pure copper
specimens made of annealed metallic wire. Fig.1
shows the dependence of the thermo e.m.f. coefficient
on the annealing time of steel previously deformed by
68%; Fig.2 shows the respective dependence for copper
annealed at 200 C in the case of reductions of 61.8
and 74.5% respectively; Fig-3 shows the respective

Fig.4 shows the dependence of the microhardness of
copper on the annealin6 time at 200 C with a
preliminary reduction of 3a- without load (curve 1)
and with load (curve 2). It can be seen from the
last mentioned curve that the softening of previously
plastically deformed copper is more intensive if
tensile stresses are applied and this con-firms
earlier expressed views on the stimulating effect of
external loads (6-9). 4 figures and 9 Slavic

ABSTRACT: Ductile deformations in metals were the subject of studiesiv
many investigators: Frenkel' /F -ef 17' Vonsovskiy, Lashko -Ref

,,_R
arrived at a conclusion that 'he origination of difIferent tKermc-
electromotive forces, t.e.m.f., for the same metal is due tc
changes in energy spectra of collectivized e-ectrons at differen-
degrees of ductile deformation. To check this hypothesis, the
authors have experimentally investigated the effect of ductile
deformation in bismuth on its Hall constant. The measurements of
the Hall e.m.f. were carried out at a constant intensity of magnetic
field, equal. to 13,000 oersted, in Bi samples which were first
deformed by one-sided pressure from i to i0 tons (these measure-
ments yielded the value of Hall constant for deformed sample, Rd)

to that of an undeformed sam'Dle, Ro). The relationship of the
ratio Ro/Rd on the magnitude of deformation F_ is presented in
Graph 1 and Table I from which is to be seen that this ratio has
a peak value at a relative deformation of 434. This is explained
by the change in the electronic density distribution and in the
energy spectrum of collectivized electrons. A further increase in
this ratio leads to the break of the sample. The results arrived
at can not be generalized to other metals, in view of tne special
position of bismuth, beine a metal of low duc-1.11',ty.

Dislocation observations were made directly on the surface of
polycrystalline silver during thermal etching in air and in vacuum.
99.9% purity silver was used in the experiments since this metal
hardly oxidizes at all at elevated temperatures. After rolling,
grinding and pelishing, the specimens were placed into a metallo-
graphic microscopes individual machining lines could be distingiiished
on the mirror surface. Annealing at relatively elevated temperatures
was by means of an electric current whereby the temperature was
measured by a thermocouple and maintained constant for each of the
specimens, During the process of annealing changes in the
reflecting surface of the silver were observed, At the initial
instant of heating all non-uniformities which arose durin%

Detection of Boundary and Screw Dislocations in Silver
At the initial instant of heating its ref lection is %ini form. After
a certain time, the grain boundaries and the defects start to he
apparent. whereby the grains boundaries and defects show up in the
same way which indicates that they have a similar structure
Figs.1 3 (plate) show photographs of the surface of the silver with
etching dislocation pittings after annealing at 8000C, On one photo
the etching pittings are on the surface of one grain and are
located in parallel rows. However. there are grains in which the
etching pittings are ordered in the centre of the grain and chaotic
at the grain boundary. On the basis of the results 1-t is concluded
that for detecting boundary and screw dislocations no special
reagents are necessary. In the same way as in germanium and
tellurium boundary dislocations may occur as ordered or chaotic
etched pittings, Screw dislocations can be detected during thermal
etching along the growth spiral as well as along the etching spiral

'TEXT: The author considers different theories about recrystalliza-
iion and its centers In the light of experiments. It is not possi-
ble, for example, to explain why there is no recrystallization for
nigh degrees of deformation (a threshold), below which even at ma-
ximum temperatures it is not posoible to show any noticeable recry-
stallization. There is also a supposition that the non-homogeneity
of deformation or difference in energies is necessary for the ap-
pearance of recrystallization. For example, using the iead samples
at temperatures of 1500C in crystals consisting of extende4 and non-
extended particles, the centers of recrystalllzation aiways appear
on the border between such parti-cles. In his experiments, the au-

thor used samples of armco - iron (0.025 % C, 0,09 % Mn, with some
traces of Si) or pure silver (99.9 %) baked after defor:--.at--on in an
electric stove at a temperature of 4500C for two hours. For the
samples with a macro-gradient the recrystallization was intensive;
for the samples with a microgradient it did not start. Only when
the temperature was increased to 6000C did the recrystallization
start in the microgradient samples. It is generally known that the
growth of crystals is connected with screw dislocations. If the
appearance of the new subblock is understood as the formation of
the recrystailization center, then the screw dislocation at high
temperatures may be recrystallization centersq since atomic iaye.-S
grow round them. On the basis of numerous experiments the author
concludes that at low temperatures the mechanism of recrystalliza-
tion is dislocational and at high temperatures dil"fusive. 1"herefore,
he comes to the same conclusion as Ya.Ye. Gegu8in and I.I. Vi8hnev-
