TITIE: Various aspects of investigation of the nature of hypersensitivity of the
delayed type and of phenomena related to it
SOURCE: Uspekhi sovremennoy biologii, v- 59, no. 2, 1965, 257-283
TOPIC TAGS: immunity, antibody antigen, enzyme, immunization
ABSTRACT: The phenomenon of hypersensitivitylof the delayed type (11DT) and
-its significance In tae formation of immunity4are discussed on the bisis of
!extensive published data oa the subject and of the nuthor0s own work. It is
tbrought out that the process of formation of immunity consists of two stagest
developmcmt of cell antibodies, I.e., of a specific complementary configura-
tion on the surfaco of mature small lymphocytes, and development of humoral
~anitbodies* Some immune lymphocytes deteriorate upon reacting with the anti-,
gen, with the result that Intracellular proteolytic enzymes are released
,which are responsible for HM reactions against transplantates, and other
.phenomena of tissue Immunity. ilie second stage of Immunization develops as
.a result of a transformation by interaction with the antigen of other Immune
lymphocytes into cells capable of developing humoral antibodies (possibly
plasma cells). By administering'only a small amount of antigen, irradiating
,experimental animals w1th_X-rays, and applying some other methods, the second

ACC NR: AP6017418
of immunizatlon~ that of formation of humoral antibodies, can be
delayed and the first stage (as Indicated by formation of HDT) produced
in,Its pure form. On administration of a large amount of antigen, the
.Second stage develops rapidly and the first Stage Call Usually not be
Aifferentiated from it. The first stage (that of formation of immune lympho-'
cytes) presumably forms the basis for lasting imiranolocgical tolerance by
;ensuri-i- persistence of the antigen in an organism that is tolerant to it.
'Although it is.generally assumed that cell antibodies cannot be separated
from dhe cells* the argumentsadvanced to this effect are not entirely
valid. JPRS)

TITLE: The Creators of Hydrocopying Semi-Automatic Machines
PERIODICAL: Mashinostroitel9, 1959, Nr 8, pp 38-40 (USSR)
ABSTRACT: The designers of the Moskovskiy stankostroitellnyy zavod
imeni Ordzhonikidze (Moscow Machine Tool Plant imeni
Ordzhonikidze), Ya.P. Mezivetskiy, B.L. Korobochkin,
I.A. Rostovtsev,Ye.F. Sokolov and the former Chief
Engineer of the plant M.M. Berman, were awarded the 1959
Lenin prize for the creation of hydrocopying semi-
automatic machine tools. The new hydraulic co-ordinate
follow-up system (Figure 1) permits the copying of parts
of any configuration within 180 limits. The plant is
producing a series of hydrocopying semi-autbmatic machines.
The three main models are: 111732" (Figure 2), "172211 (Fi-
gure 3) and "1?12" (Figure 4), designed mainly for the
machining of multistage parts with conical,, cylindrical

and shaped journals of 15 to 320 mm in diameter and 150-
1,600 mm long. At the zavod imeni Likhacheva(Plant
imeni Likhachev) it takes only 15-20 minutes to reset
such a machine for installation in automatic lines. The
automatic line containing two hydrocopying machines,
which received the Grand Prix at Brussels, will soon be
available to the machine building industry. At present,
the designers are completing a hydrocopying machine with
program control. Ivan Alexandrovich Rostovtsev, Chief
Designer of the plant, has received many letters of
praise from the Nizhnetagillskiy "Uralvagonzavod" (Nizhniy

TITLE: A simplified approach to automobile radio interference level testing
SOURCE: Avtomobillnaya promyshlennost', no. 8, 1965, 34-35
TOPIC TAGS: radio transmission, automobile, interference measurement
ABSTRACT: The All-Union standards for tolerable industrially-produced radio interference
levels also apply to automobiles. The present article describes a small-scale test stand to
ipeasure radio Interference levels of automobiles simply and inexpensively. The stand Is
rpade of two mutually insulated plates the size and location of which are selected so as to
achieve a sufficiently large capacitance between the upper plate and the car body (reasonable
coupling) while maintaining a low capacitance between the two plates. This capacitance
determines the magnitude of the*HF resistance which Is used to measure the voltage generated
b~ the interference current between the automobile and the lower plate (ground). The article
also gives all the pertinent formulas for the calculation of the interference level and gives
some reBV1t0 obtained with GAZ-6 3 and ZIL- 130 automobiles. Orig. art. has: 8 formulas,
2 figures, and 2 tables.

TITLE: Determination of the Diffusion Coefficient According to the
Method of Residual Gamma Aotivity
PERIODICAL: Zavodskaya laboratoriya, 1959o Vol 25P Nr 9, pp 1072-1074 (USSR)
ABSTRACT: The simplified method (Ref 3) of the removal of thin layers for
the determination of diffusion in solid bodies based upon a
measurement of the difference of radioactivity in a certain
layer depth, contain a large determination error. It was found
that, if the diffusion coefficient (3)) is not determined
according to the gamma activity, but according to the absolute
values, the determination accuracy may be increased, For this
purpose the relationship between the value of-the integral g a
activity of the sample, from which a layer of the thickness h
was taken', and the value (D) must be determined. A diagram of

TEXT: The paper describes experimental work done to clarify the dependence
of the volu*metric self-diffusion (SD) parameters of Mo on two factors: (1) the
amount of alloying Zr present; (2) the antecedent cold-working of Mo alloys. The
work is intended as a contribution to correlations between the rate of self-diffusion
and creep, such as those which 0. D. Sherby, R. L. Orr, et al. have tried to estab.-
lish causally (J. of Metals, v. 6, no. 1, Sect. 1, 1954, 71-79; Tr ans. ASM, V. 46, 1954,
113-128). Test material and methodology: Large-grain specimens were used to
reduce the W-hare-o-f-b-ou-n-aary d7iffusion in tfie total diffusional flux. The Mo and its
Zr alloys were vacuum arc-smelted, rolled into an 18-mm diam rod, and high-T
annealed at above 1700OC; the alloys ranged from 0.00516 Zr to 0.54% Zr. Right-
cylindrical plane-parallel specimens 14-mm diam., 4-mm high, were'cut oui of the
rods and were subjected to a 10-15-hr stabilizing anneal at 1,950-2,0000C in a
10- 3_ 10-4torr vacuum, whereupon the grain size in all specimens attained 1-2 mm.

Part of the specimens were upset on a press at 200 (height reduction 255o) to investi-
gate the effect of cold working on the SD of the Mo. The specimens were electrically
polished, whereupon one of their faces was activated with radioactive Mo99 in a
galvanic bath. Diffusion anneal was then performed in a special vacuum furnace
(exploded view shown) at 10-3_10-4 torr and 1,7ZO-Z,0000G. The SD coefficient was
measured by the two senior authors' method (Zavodskaya laboratoriya, no.7, 1960,
828-830) based on the shift in the activity curve (summarized). Test results: The
self-diffusion parameters measured (and tabulated) indicate an apprec-la-ble augmen-
tation effect of even small additions of Zr on both the self-diffusion activation energy
of the Mo and the factor before the exponential term. Thus, at T above 2,0000C the
SD coefficient of Mo does not depend on the alloying, but at T below 1,7000, in which
the value of the activation energy is decisive, the SD rate decreases with increasing
Zr content (numerical values tabulated). Even though antecedent cold-working de-
presses the SD activation energy of the Mo in Mo-Zr alloys, the activation energy
of upset specimen increases with increasing Zr content. Inasmuch as the diffusion
anneal of the deformed alloys was performed at a T substantially above their recrys-
tallization T, the latter was complet6d in but a fraction of the anneal time, and the
diffusion in the grain volume continued through an extended time in the absence of
any structural transformation, so that any observed lowering of the SD activation
energy of the Mo is regarded as a result of irreversible structural changes attribu-

table to the cold-working of the alloy. The increase in activation energy during the
anneal is attributed to a healing of c rys talline -lattice defects which previously had
served as "short-cut paths" for the diffusion; cold-working appears to firm up the
defects, thereby inhibiting the healing effect of the anneal. The relationship between
the SD coefficient and the activation energy is further examined and, in agreement
with G. J. Dienes (J. Appl. Phys., v.Zl, no.11, 1950,1189) and 3 Soviet authors, is
found to be exponential. The results of this investigation agree with existing
knowledge on the favorable effect of relatively small additions to Mo on its recrys-
tallization T, its hardness (ref. Pipitz, E., Kieffer, R. , Za. f. Metallkunde, v. 46,
no. 3, 1955, 187-194), and its high-T stress-rupture strength (Northcoitt, L.

investigated and remained in their original lattice positions,
despite substantial changes in the structure of the metal.
The behaviour of carbon atoms was substantially different:
above 7500C carbon passed from the boundaries of deformed grains
to the boundaries of now recrystallized grains. However, in the
initial stages of recrystallization (after 30 to 45 min at
650 to 7500C) carbon atoms remain at the boundaries of thu i ii i ( .,I
grains and boundaries of the new grains remain free from carbou.
The possibility of "heredity", i.e. preservation of the initial
structural and concentration non-uniformities in recrystalli7.ed
metal was demonstrated on a molybdenum alloy (0-540 Zr, O.,~Oj~' --r,
0.0008% Ti and 0.01150' C). A thin layer of tungsten 185 was
electrodeposited on the surface of a flat specimen of the deforwrd
alloy, submitted to a preliminary annealing at 17000C. The
activated specimen was than annealed in vacuo at 17500C for
100 hours. Autoradiographs of an oblique section showed the
presence of an accelerated diffusion not only along the boundaries
of the newly forined grains but also a preferential penetration of

passing before recrystallization. The velocity of diffusion
along the old boundaries was lower than along the new boundaries,
nevertheless it was noticeably faster than-volume diffusion.
The results confirmed that within the grains the process of grain
boundary migration does not produce as high -concentration of
defects as is produced at the,beginning and at the end of the

ABSTRACT: Alloy!k representing solid solutions of rhenium'-In molybdenum are
characterized by unusual plasticity at low temperatures and by a high recrystalli -
zation threshold. However, an Re content of 50% represents the limit of solubilit,
iabove which-precipitation of the sigma phase begins, accompanied by considerable
embrittlement. The processes of solution and precipitation of a phase In a solid
isolution'are-to a great extent determined by the diffuilonal mobility of.the atoms
of the alloy components. For this reason, measurement of diffusion constant's Is
useful for estimation ofthe-temperature- and time-dependent stability of the plas-!_

ABSTRACT: Curves characterizing the temperature dependence of internal friction
in cold-worked metals sometimes show a peak which is reduced after low-temperature
annealing and which disappears after recrystallization, Previous studies with
iron have shown that a significant increase in internal friction can be produced
only by relatively free dislocations existing within the sub-grains, and onf~'in
the presence of dissolved nitrogen and oxygen. In the present study, wire made of
sintered Molybdenum and binary alloys of molybdenum with zirconium (0.13%) and

rhenium (50%) was investigated for internal friction after plastic deformation,
and an attempt was made to correlate the temperature dependence of the maximal
internal friction with the grain size. The wire was subjected to torsional
oscillations (0.35-0.4 cycles/sec.) in a vacuum at 20-1000C, and the total defor-
ration in the elastic range was considered to be the sum of the deformations
arising from displacement of atoms and the bending of dislocation loops in a three-
dimensional lattice. The results are shown in the Enclosure. It can be shown
theoretically that a material containing dislocations has a lower shear modulus
than a ma terial without dislocations, and that plastic deform tion increases the
density of dislocationa.inside the metal grains. In freshly deformed meLals,
there are considerable distortions inside the subgrains. Annealing below the
recrystallization temperature reduces the-inner distortions because of poly-
gonization, and decreases the deficiency of the shear modulus. The present
results indicate that the intensive fixation of dislocations by polygonization,
interactions with point defects and other processes occurs in a temperature range
of 250-600C. The maximal internal friction shifts toward lower temperatures
with increasing plastic deformation, and toward higher temperatures with coarser
grain,structure. The irreversible decrease in internal friction at temperatures

nigner than that corresponding to the maximal internal friction can be explained
not only by an increase in the diffusional mobility of the atoms, but also by a
decrease in the number of relatively free dislocations caused by polygonization
procesoC6, The absence of an interruil friction peak after plaotic deformation of
the Yo450'/.Re alloy leads the authors to the conclusion that, in this alloy,
plastic deformation is not accompanied by creation of a sufficient number of
relatively free dislocations. Orig. art. hast 3 figures and 3 formulas.

annealing. This indicates that even prolonged diffusion annealing
.does not eliminate structural defects in places where the initial
grain boundaries were located. In the molybdenum

,(0.54% zirconium) the phenomenon' was expressed much more sharpl)r than
.in unalloyed molybdenum, owing probably to the presence of very stable
:zirconium compounds (either oxide or carbide type). The diffusion

higher density of defects than is found along the old boundaries. It
.is suggested that-the phenomenon observed can be utilized for improv-
ing the ductility of mol bdenum at room temperature. Under certain
conditions at reerystallrzation it could be expected that the old
boundaries would serve as a kind of trap for the atoms of harmful
.1intetstidals such. as carbon, oxygen, and nitrogen, and would thus reduce
the content of these intaratitials in the now grain boundaries. Orig.

ABSTRACT: One of the methods for studying rate of vaporization is continuous weigh~,-
ing of specimens during isothermal holding in a vacuum. When the specimens are
metals which have a strong affinity for oxygen, two characteristic periods may be
distinguished on kinetic curves for weight loss. In the first period, the loss in
weight increases with time, then after reaching a maximum value the loss rer'~ins
constant in the second period (see fig. I of the Enclosure). This increase in the
rate of sublimation at the beginning of isothermal annealing is due to gradual des-
truction of the oxide fi urface of the specimen. Kinetic curves for
weight loss in some a5TO-Yte a similar shape. If the alloy base has a considerab-
ly lower vapor pressure than the dissolved material, there is a third period on
the curve where the rate of sublimation decreases due to a reduction in the concen-:.
of the volatile component on the surface of the sample. Aluminum-zinc and

:t
aluminum-magnesium-alloys are examples of such systems. The authors study the
first stage of the sublimation process. Thermal dissolution of magnesium and alu-
minum oxides is practically impossible at experimental temperatures because of their
thermal stabi-lity. Therefore there should be another mechanism responsible for the
destruction of these films. Nearly all surface films on metals except for aluminum
have various types of microscopic discontinuities. During isothermal annealing in
a vacuum, atoms of the volatile component pass through these defects and leave the
surface of the metal, thus increasing the concentration of vacancies in the defect
zone. Vacancy coagulation takes place due to the interface between the oxide film
-ion of microscopic pores close to this interface,
and the metal. With the formal
the bond between substrate and oxide film is broken and the film is destroyed, in-
creasing the defect area& Thus the minority atoms are more rapidly evaporated,
microscopic pores are formed and the autocatalytic process of film removal is ac-
celerated. A kinetic equation is proposed for the process of sublimation when there
is an oxide.film on the surface of the metal. Theoretical calculations show ex-
cellent agreement with experimental results. Orig. art, has: 3 figures, 14 formu-*

ABSTRACT: Theoretical and experimental studies have been madf&of the sublimation'
and mechanism of.the breakdown in the presence of an oxidized~hurface layer of
VM65-1 magnesium-baBe alloy (5-62 Zn, 0.3-0.9% Zr) and V05 luminum-base alloy

W2.5% Mg and 6Z Zn) In a vacuum of 10 peratull of 200-380C. it
was found that i2ii Iloy vM asurface oxide film sublimated slowly at 200 or
250C for the first 12-15 hr; then the sublimation rate increased sharply. Speci-
mens which were vacuum annealed at 300C for 4 hr prior to testing sublimated at a
high rate from the very beginning of the test (see Fig. 1). The weight of surface-
oxidized V95 alloy specimens does not change at 300C for 4 hr. However, at 350C
rapid sublimation begins after 10-15'min. Annealing at 340C removes the oxide
film, eliminates the inoculation period, and induces rapid sublimation (as in the

TEXT*. A number of arrestor designs have been published in
which the arc quenching in by means of the magnetic field, The
arc quenching ability of spark gaps, which are similar to arrestors,
is determined in the first instance by the behaviour of a short
electric arc in a magnetic field. This behaviour is also important
in various other electrical apparatus. On the basis of published
data, the author reviews the behaviour of an electric arc between
electrodes of non-magnetic materials generally, mentioning briefly
the results of G. A, Kukekov (Ref.1), N. A. Babakov (Ref.2),
0. B. Bron (Ref.3), V. V. Shmatovich (Ref.4) as well as American
and British results (Refs-5-16). Furthermore, he analyzes
published results on the speed of movement of the arc in the
various zones of the gap an functions of the field strnngth and the
current intensity and also the behaviour of the arc at reduced
atmospheric pressure and in various gases, including the anomalous
foreverse" movement of the are. In the latter part of the article

Movement of a Short Electric Arc in a Magnetic Field
a similar analysis is given of published results on short electric
area between ;electrodes made of ferromagnetic. material, paying
particular attention to d.c. arcs. The following conclusions are
arrived att
1) The movement of a short electric arc in a magnetic field depends
on the current intensity, the field potential, the inter-electrode
gap, the material and the state of the surface of the electrodes.
With increasing current intensity and magnetic field potential, the
speed of are movement increases in all cases.
2) In the case of gaps between non-magnetic electrodes in excess of
1.3 to 3 mm, the speed of movement of arcs depends little on the
material of the electrodes or the state of their lsutfac'es~ ~ -,* -
With decreasing distance between the electrodes the speed increases,
reaching tens of metres per second. The speed drops by a factor
of 2 to 3 in the case of field potentials below the critical one,
which is estimated at tens of oersted.
3) In the case of smaller gaps between non-magnetic electrodes, the
speed of movement of the arc depends to a considerable extent on the
state of the electrode surfacesQ It reaches tens of metres per
