ABSTBACT: One method of increasing the output of hydraulic -presses
is to replace manual by semi-automatic control'. The
bydraulic circuit of a 100 ton press.-provided with semi-
automatic control is illustrated in Fij.1 which also
gives a table of valve positions at different times in
the operating cycle. Pig'.2 illustrates the construction
of a valve the operation of which is based on that of the
so-called floating valve. The principles of operation of
the valve are described. The operation of the automatic
circuit is also described. A special procedure is adopted
to slow down the press just before it closes on the tool.
The electrical circuit of the equipment is given in Fig.3.
With semi-automatic 'control of the press only two push-
Card buttons are required. All the remaining switching is
1/2 carried out automatically. The circuit provides reliable

TITLE: Service Reliability of TV Sets (Ob ekspluatatsionnoy nadezhnosti
televizorov)
PERIODICAL: Radio, 1957, Nr 4, p 49 (USSR)
ABSTRACT: New models of TV sets are coming on the market; however, their ser-
vice reliability receives very little attention. When checked while still in the
store, the TV sets showed various defects, the elimination of which would re-
quire a laboratory check and alignment. The defects are: sweep non-linearity,
twitching of the picture, absence of smooth control of the-contrast, presence of
white strips dragging behind the dark spots in the picture, multiple outlines,
disturbance of the interlaced scanning, diversification of tuning, and ac hum in
the sound system. Many TV sets have microphonic effect and sound-signal
penetration into the video channel. All such defects should have been eliminated
at the factory. Manufacturing plants give a six-months' guarantee on TV sets.
This guarantee does not mean faultless operation for six months but, rather, a
free repair service for that period. The TV repair shops are inadequate and do
not have enough parts in stock. Repairmen rendering home servicing of TV

mechanical sweep of the n -shaped ulse is analyzedp and these two methods for the
..error elimination are sug Generation of a nonuniform sequence of filling

scale pulses by-an LO-oscillator; (2) Same., by an RC-oscillator. In the first method,
the Boale-pulse frequency is calculated by a variable.capaoitor whose plates are
shaped to compensate for the nonlinearity of the sweep. In the second case, the same
results are achieved by calculating a luminous flux falling on a photoresistor orby

PERIODICAL: Vestnik Vysshey Shkoly, 1957, # 10, pp 27-32 (USSR)
ABSTRACT: The author states that the study of the Party history in
seminars and discussions must be conducted in such a manner
that the students will not only be able to understand
historical events but also to evaluate actual facts. The
teacher must encourage the students to ask questions on the
causes, the social importance and the trends of certain
events. He then gives examples of methods of treating such
events as the Kronstadt Revolt in 1921, or the events in
Hungary in 1956, such policies as peaceful co-existence,
workers' council growth (as in Yugoslavia, Hungary, Poland),
the recent Malenkov, Kaganovich, Molotov apostasy, etc.
He concludes that it is difficult for the students to
select the actual facts on the subject; that this is the
task of the teacher. He then suggests establishing a list
of complementary literature.

The absorption spectrum (at 2930K) of noncolored single crystals
NO~aAg (0.02 mol%) reveals bands at 220, 230 and 245 mil. irradiation by
C-0 gam -rays creates weak bands at 290 an~ 44b mp and an intensive,
Y~band at 565 W. An additive coloring in K vapors at a temperature not
-over 5000C creates intensive bands at 290 qa. The crystal gets yellow.,
and under further irradiation, violet. Bands at 44o and 465 W the author
identifies as K-band of KCI. The relative intensity of F- and K- bands
depends on the method of coloring, and therefore, the K-band cannot occur
by electron transit to F-centers in higber excited states. The author
attributes it to alkali metal particles in the lattice o' 1X1. Th(- crYs-
tals M01-Ag reveal some distortions of the lattice. The position of the
K-band does not depend on temperature. (U)

ABSTRACT Lecture delivered at the All Union Confer-*nce for Semiconductors in No-
vember 1955 at Leningrad. The most intense stripes of additional absorp-
tion have their maxima st wavelengths of 45o and 29o m. The first absorp-
tion strips has its maximum at waiel*igths of 44o or 465 m. This is connee-
t*d with superposition by absorption curves of the new stripes and the F_
strips. The strips of additonal absorptiom has its maximum at a wavelength
of 465 m. If the F-stripe in lacking the maximum is at 44om. Between the
F-stripe and the short-wave side an absorption with a maximum at 465 zm was
observed if an F-stripe existed and at 44orm if the F-stripe was lacking.
The author identifies the absorption stripe in the case of a wavelength of
44o nm with that of K in colored KC1 crystals. If yellow orystals are ir-
radiated with X-rays a strong F-atripe appears, and with it the stripe
grows considerably with the maximum at a wavelength of 44o rm. On this oc-
casiox the crystal turns violet. It was found m a result o f these exper-
iments that on the shortwave side a considerable stripe is obtained with
respect to the F-stripe (K-stripe) alsoin El crystals without &a admix-
ture of Ag. This is the easp if the KC1 6rystals are electrolytically co-
lored at 5ooo C and if, at the same time, they are illuminated with Vi31b-
Card 1/2 le light. The K-stripe then has its maximum at the wavelength of 465 xm.

ABSTRACT: 'In an extension of the authors' previous work, the influence of
F-centers on plasticity and the influence of reactor radiation on plasticity
and thermal conductivity were examined in Kel crystals. 1he influence of
reactor radiation on plasticity was also examined in LiF crystals. F-centers
were produced by x-raying in a RUP-200-20-4 unit and an IRT-200 reactor was
used for neutron and gamma radiations. Hardness was measured by the scratching
and the pendulum swing damping methods. -Optical absorption spectra were measur-

ed with an SF-4 spectrophotometer and an assembly, based on the principles of
A.V. Ioffe and A.F. loffe and constructed in the authors' laboratory, was used
for the determination of thermal conductivity. This method was applicable at
close-to-room temperatures and, in a 5 minute procedure, produced results with
an accuracy of 3-5 per cent. At least one hundred samples were examined.
Curves for the dependence of hardness on the duration of x-raying and the con-
centration of F-centers showed a steady growth of plasticity of KCI crystals
for the duration of x-raying, accompanied by the accumulation of F-centers.
Under the influence of reactor radiation KC1 crystals showed an initial growth
of microhardness, which ceases when a dose of.,4~ 1016 neutron/cm2 is reached.
In contrast, the resistance to plastic deformation and mechanical strength
continued to grow in LiF crystals. The thermal conductivity of KCI crystals
under reactor radiation followed acomplex pattern, showing an initial decrease,
followed by an increase aa radiation continued. Orig. art. has: 11 figures.

COVMGE: This Is a collection of papers presented at the
Moscow Conference on the Kffect of Nuclear Radiation on
Materials, held December 6-lo, 1960. The material reflects
certain trends In the work being conducted in the Soviet
scientific research orginization. Some of the papers are
devoted to the experimental study of the effect of neutron
irradiation on reactor materials (steel, ferrous alloys,
molybdenum, avialgraphite, and n1ohromea). Others deal
with the theory of neutron irradiation effects (physico-
chemical transformations, relaxation of Internal stresses)
internal friction) and changes in tfie structure and proper-o
ties of various crystals. Special attention is given to
the effect of Intense- V-radiation on the electrical,
magnetic, and optical-properties of metals, dielectrics,
and semiconducto".

ABSTRACT: An investigation was made of the relationship between the change in micro-
structure and the optical properties of coloration centers in potassium-chloride
.crystals irradiated in a reactor. Such investigations are important since F-center-
trpe point defects exert a strong,effect on fundamental properties such as stability$
t'iermal conductivity, etc. Coloration cent6rs are also used in studying the inter-
..atztion of electron, hole, ion,.and dislocation processes due to neutron irradiation
Ii solid bodies such as alkali halide crystals, An attempt was thus made to show
tiat dhanges in microstructure determine thegeneration. and interaction of local
electron and hole centers in irradiated alkali-halide crystals. Specimens 13 x 10
x 1-1. 5 mm, unannealed and "polished# were simultaneously irradiated in an atomic,
tor with neutron fluxes from 1,8 x 1015 to 3.6 X 1017 n/cmz under identical t

conditions. New "270 mp" and "310 mp" bands, previously unknown for cry
erved in the absorption spectra. Absorption bands
.,,.irradiated with x-rays, were obs
associated with aggregate coloration centers (RI, R2, M, and N) possessed higher
thermal stability in, comparison with crystals irradiated with x-rays. This was
attributed to the appearance of inner emitters,.upon which the effect of seli-
coloration depends. 'The halfwidth of the separated F-band in all crystals irradiated
in the reactor, indapendently of irradiation dose, exceeded the halfwidth of the
~,,F-band in crystals irradiated with x-rays- A self-coloration F-band appeared in
crystals irradiated
-in,the reactor and then discolored either optically or thermally,
The halfwidth of this band
-coincided with the halfwidth of the F-band before dis-
coloration. A dependence of the halfwidth ofthe F-band on the integrated neutron
flux and a correlation:between the change of' the halfwidth and the change of dis-
location density.and stability characteristics was observed. The widening effect of
the F-band and th~"dq.se dependence of the hstlfwidthwere attributed to-radiative
'damage of the crystal lattice. Orig., art. - bAd:

the Hm, Hs, and HP of KC1 crystals. Prolonged irradiation may result in increased Hp.

.insignificantly. LiF crystals irradiated by neutron flux were colored more strongly
,,than KCI crystals. Both LiF and KC1 crystals vere strengthened, although strengthen-
ing of the LiF crystals was greater than that of the K.Cl crystals. The~;ztrengthenl%
,:effects were apparently not associated directly 'with the coloration of the crystals.
The effects of neutron flux irradiat3.,on of KC1 crystals varied according to the type
;of hardness. At small irradiation doses H and H decreased sharply. At doses up to
9 x 1015 8
n/cM2' H vas .30% lower than in nonirradYated specimens and H p 20% lower.
.After reaching a,minimum, H and.Hp began to increase and at -16 x lois n/cm2 they
reached their initial values. In the beginning Hm increased and then reached satura-
tion. The removal of thermal neutrons from the flux by means of cadmium filters had
virtually no effect on the dose dependence of the types of M crystal hardness
studied. Changes.in the irradiation temperature changed the behavior of the hardness.~
For instance, Hs of KC1 crystals decreased when irradiated with doses up to 9 x 10 15
I/cm2' while at low temperature irradiation increased. Hp behaved similarly. Orig.

ABSTRACT: In view of
neutrons in irradiated3'glkali-halidep~'Jingle crystals, the authors
irradiated KBr and NaCl single crystals with gamma rays from the In-Ga
radiation loop in the reactor of the Georgian Academy Physics Institute,
The dose rate was 0.8 x 106 r/hr, Before irradiation the crystal
was cooled and placed in the path of a monochromated beam of neutrons.
The resolution was 25% in terms of the wavelength Iwhich ranged from
I to 12 The maximum background i-,7as 0.08 neut/cm2. The sample

the transmission was 0.6-0.9 in the indicated wavelength interval.
~To suppress the inelastic scattering of neutrons by thermal lattice
vibrations, the experiment was carried out at liquid-air temperature.
The intensity of the neutron beam passing through the irradiated
crystal was compared with the intensity through the same crystal
prior to irradiation Neutron scattering maximum was observed at wave-
lengths between 5 and 8 A. The height of the maximum increased in
to'the irradiation time. A similar curve was obtained also
proportion
for 20 hours' exposure, but the measurement error was quite large.
The scattering of neutrons by defects in irradiated crystals is even
more strongly pronounced in NaCl crystals. The preliminary experi-
ments have shown that at wavelengths correspondinj; to the maximum on
the curve, the intensity of the neutrons scattered at an angle increasen
somewhat. To check whether the observed effect is connected with the
occurrence of color centers in the irradiated single crystals of the
alkali-halide salts, the concentration of F and M centers was measured
in the wavelength.interval 220-1000 nm. It was found that the maximum
concentration of F-centers is 7 x L017 cm-3, and the number of H centers
is much lower. Such small concentrations cannot explain the observed
change in ndutron transmission. The authors thank Professor Yu. M.

citical absorWon were found to agree in slope with the maximum occur-
ring at 15,10 5 neutron/CM2. The maximum is due to the dissolution of
dislocations accompanied by an injection of vacancies into the crystal
and the capture of electrons by injected anion vacancies. The observed
EPR spectrum consists or two superimposed lines: a wide line determinedl
by F-centers distributed evenly within the crystal, and a narrow one
with the concentration of F-centers near the dislocations. Thus, the
width of the total EPR spectrum depends on the concentration of F-
centers and on the density of dislocations, In irradiating samples with

IThe effect of annealing on dislocation density is described. The dependence of dislo-.
cation density in LiF crystals on the temperature during irradiation confirms the con-!
Idensation theory of dislocation generation. Selective etching of the tesT samples
,revealed the nature and distribution of point defects. Microphotographs of crystals
etched after irradiation show extensive pitting, which increases with higher dosages.
lEffects of irradiation and subsequent annealing on the density and nature of pitting
land the mechanical properties of the crystals are described. From the experimental
!'data it is concluded that irradiation causes point defects to merge. These defects
have greater dynamic resistance to the motion of dislocations than do individual va-
icancies, interstitial atoms, and individual impurity atoms. Annealing causes the
point defects to unite into plane cavities. The annealing time and temperature and
the rete of cooling all affect the mechanical properties of the irvadiated crystals.

Afte-r irradiation, peak 1 vanished, whereas peak 2 grew sharply. The tes-cs were re-
pea7zed after 3 days, during which the crystals were maintained at room tenparature.
.Peal: 1 reappeared and peak 2 decreased somewhat. Upon reexposure to x-rays, peak 1 de-
creased, but not as much as the first time. The crystals were subjected 'ro 19. deforma-1,
tion, which was found to have an effect opposite to that of x-irradiation: peak I
grel 1. whereas peak 2 fell. After 3 days at room temperature, the peaks returned to
:theJ.r initial state. The rise and fall of the peaks i-s explained as due to the Schul-
man-Compton mechanism, in which vacancies are generated by the irradiation, coupled
~with Varley's multiple ionization and Seitz's dislocation mechanisms. The excitons
foivied by the x-rays decay and the halogen ion localized at the line of dislocation
'ionizes. -the resulting atom departs, leaving a vacancy. The decay of another neigh- ;i
boring exciton causes one of the halogen ions of the normal lattice to fill the vacan-
cy, leaving a free halogen vacancy. This mechanism results in a drift of the disloca-
.tions. The effect of deformation on the behavior of the peaks is explained. Peak 1
,is associated with "dislocation" type internal friction; peak 2 with "vacancy" type in-~
!ternal friction. However, the latter conclusion is not clear-cut. Orig. art. has: 6
