TEXT: An engine oil for two-stroke gasoline engines, which is introduced
into the engine mixed with the gasoline, is produced from the aromatic
extract from selective-refined mineral oils by using propane extraction to
remove the polycyclic compounds from the extract, adsorption refining,
H2so 4 refining or hydrofining. The polycyclic compounds can be removed
from the extract in a mixture with a hydrocarbon solvent such as white
spirit, diesel fuel or used ;ngine oil. The refined mixture obtained in
this way is used as the engine'oil. For example a medium extract
(viscosity 360 cat/500C) was dissolved in white spirit to a viscosity of
75 cat/500C and then refined with 3 - 4 ~- H2 so 41 lixiviatedt washed with
water and driedl a refined product was obtained consisting of 75 % oil and

TITLE: Etching Patterns of Elastic Calcite Twins
PERIODICAL: Doklady Akademii nauk SSSR, 1959, Vol 128, Nr 3, FP 4?,--.Ol
(USSR)
ABSTRACT: It appeared to be of some interest to investigate the lv.,-
patterns of the crystal during the formation of elastic ir.s,
which differ from twin intermediate layers by their wedg-
shaped appearance. Besides, the original position of the
crystal planes is not yet found when investigating the elastic
tidn formation in the mother cryatal. Strong def ormati ons irE
thus caused in the neighborhood of the elastic twin. The
latter have already been described by R. I. Garber (Ref 4)
(see also G. B, Rays, Refs 1, 2). An elastic twin of th~
dinary shape was completely contained within the sample a:,.
did not cause any particularities on its surface which occur
on etching. It was particularly interesting that the twin left
the crystal for the shear plane. The performance of these
experiments is briefly described. Etching traces in the form
of small slits occurred on the face along the line of inter-
Card 1/3 section of the elastic twins and the surface crystal face.

~'tching Patterns of Slastic Calcite Twins SOV/20-128-3-18/58
The etching patterns of the elasiic twins are illustrated in
a figure. They expand with decreasing thickness of the twin,
Narrow lines occur on the etching of deformed crystals. The
former are probably special deformation lines, which have
not yet been found in calcite. By changing the distance from
the point of contact of the wedge with the crystal up to the
polished face, and also by changing the strain, it is possible
to obtain various cross sections of the elastic twin with
polished surface and, consequently, with different length of
the etching trace, provided the twin length is given. Another
figure shows the formation of a parallelogram on the etching
pattern near the vertex of the elestic twin. This parallelo-
gram forms the base of a roof-ohaped cavity which is formed
at the sharp edge of the elitatio tni.n or. etching. The fourth
figure illustrates the arrangeman'. c'L the traces of the clpava6e

PERIODICAL: Fizika tverdogo tela, v. 3, no. 12, 1961, 514-519
TEXT: 1ri order to investigate plastic deformations in twinning it is
necessary to study structure and properties of the boundary layer in a
twin crystal rind parent crystal. It has already been investigated for
several times experimentally by using etch patterns and theoretically
by assuming that the boundary has a dislocation characteristic. In a
previous paper tiie author has already reported on investigations, which
lie had done on a wedge-shaped twin. This paper reports on stuL_es which
have been cone to clear the nature of defects appearing at the boundaries
of twin and parent crystals. The inve8tigations have been done on calcite
crystals which had been deformed by shearing and had also been etched
with a weak etching solution of type C_"4 (SR-4). Etch patterns have
been producea titid observe,l under various conditions. Under a NO times

openings which are arra_,~,gea in rows. These results and those of the
previous paper fDAN SSSRj 126,no.3,495-0959) make it possible to draw
conclusions on the mechanism for defects to occur at boundary of twins.
Similar assumption3 are used with respect to the position of cleavage
faces of a wed&e-shaped tw4tri, as used by K, V. Vladimirskiy. It has been
found that etch patterns at the twin boundary would occur due to the
presence of finest layers of untwinned material at these boundaries;the
edges of' these `a,~,ers are bounded by twinning dislocations. During
the fusion of the boundaries in a reciprocal twinning or in a twinning
of a sem-, synthetic twin small islands of untwinnea material with twinning
dislocations at their edges will occur in the sample. At these places
there are etce patterns wh_,cr, are similar tc those observed at the
boundary of twin layers. Clogeed islands with disloptions can be re-
moved by suffiziently high shear stresses (100C g/mm ) with corresponding
signs~ 'here are 5 figures zind 9 references: 7 5oviet-bloc and 2 non-

TITLEs Mechanism of mixing of dislocations during elastic twinning
PERIODICALs Fizika tverdogo tela, v. 5, no. 1, 1963, 211 219
TE.~T: Formation and variation of elastic twins in calcite crystals was in-
vestigated by photographing and photometrizing the transmission interference
patterns. The elastic twins were created by pressing a steel ball against
a crystal face. Lenrth and thickness of the wedge~-shaped twine were pro-
portionnl to the load. The creation of the twin and its growth depended
greatly on the stress distribution inside the crystal, i. e. not only on
the load but also on the ball radius. Balis of different dimensions but
impressed with equal loads yielded twins of different length and thickness;
the greater the ball diameter the shorter the twin; twins of equal length
were thinner when produced by a larger ball. When changing from loading
to unloading, or vice versa, the twinning process shows a hysteresis effect
with respect to the twin length. This effect is due to the change in sign
of the dislocation friction forces (Peierls forces) when changing from
Card 112

S/161/63/005/001/052/064
Mechanism of mixing of ... B1021B186
loadin,~- to unloading. The kind qf hysteresis depends on the ratio between
Peierls forces and surface tension. In calcite the Feierls forces are
rather weak. The length of the hysteresis reizion decreases with the twin
length and it vanishes at 0.1-0.2 mm twin length. The rules governing .
shape and growth of elastic twins depend.uniquely on the dislocation dis-
tribution along the twin and this distribution is determined by the crystal
defects and the Peierls forces. There are 7 figures.

ABSTRACT: The vanishing of elastic twins in calcite following a rapid removal
the load was measured by high speed motion picture photography. A diagram of the
equipment is shown in Fig. 1 of the enclosure., and an FP-22 camera was used for
the photography. An additional lens in front of the camera made it possible to
take pictures in natural size on 8 = film at.100,00C frames per sec:ond. The re-.
sults have shown that the speeds of the twins reach tens of meters per secondf
which is much higher than the value obtained ~y F. P. Bowden and R. E. Cooper
(Nature v. 195, 1091., 1962). An analysis of the kinetics of stress removal in a
crystal leads to the assumption that the speed of the twinning disLDcations in

calcite can be not lower than 100. M/sec. The temperature dependence of the pro-
cess was determined by placing heating coils, wound on flat thin mica plates, on
both sides of the crystal. These heaters could raise the sample ter;)erature to
4000. Tests have shown that the speed of the process increases with increasing
temperature. "The authors thank Ye. V. Ku_llh_av and V. A. Arinichg of the Unia-

ABSTRACT: The authors propose a new mechanism for multiplication of tvianing dis-
locations, which may be effective in the case of crystals with a limited number of
sources, The mechanism is similar to that which gives rise to slip dislocations
near inclusions in a perfect crystal at sufficiently low general stress level, as
observed by J. J. Gilman (J, Appl. Phys. v. 30, 1584, 1959), differing from the
latter only in that the elastic field of the twinning dislocations movirg In the
neighboring layer may also participate in the production of the loop ane). may also
be concentrated on the Inclusion, The newly produced loops expand Under the In-
-fluence of applied stresses and give rise to nev loops on concentrator Inclusior-s
which they encounters This possibility of dislocation-loop nucleation on the con-
C,,d 1/2

centratorg in con,,4unction with the low energy,of formation of a tvo-dimension&l
1. nucleus on the boundary between the twin and the Went crystal. may make possible
transverse growth of a twin layer due to the formation of plain nuclei on the
boundary in the presence of random inclusions near the boundary. Such a. mechaniam',
agrees with the features of twinning in'calcite. The concentrators may be of dlf-i:
ferent sizes and may concentrate the stresses in different manners. Tht estimated!
critical dimensions of the created stable--loops, assumingthestress on the bound-i.
ary between the twin and the parent crystal to be In the range from ho tohoo` - j
g/mM2, is from 0.3 x 10-3 to 0.3 x 10-4 cm. It is pointed out in the conclusion
that the described mechanism is suitable for any'crystal, being independent of i
the structure, and does not pertain to twin formation in perfect crystals. "The
authors thank A. M. Kosevich, Is A. Gindin, and V. L. Indedbom for a diacussion of

TITLE: Spatial coherence measurement of gas laser output
SOURCE: Acta physica polonica, v. 29, no. 6, 1966, 753-757
TOPIC TACS: izsnr, gas laser, laser beam, laser emission coherence
ABSTRACT: An investigation was made of the spatial coherence of an lie-lhi laser beazl.
Measurements were made of the output radiation of a cw He-Ne gas laser opez-ating at
6328 A. The laser consisted of a quartz discharge tube 995 mm long filled with -lie
at 0.5 mm lig and Ne at 0.1 mm Hg. The Lube, which was terminated with optical flats
oriented at Brewster's angle, was made of high-optical-quality synthetic fused
silica. The tube was placed between two external confocal spherical refiectors
mounted 111.4 cm apart. The reflectors, which consisted of vapor-deposited dielec-
tric layers, had reflection coefficients of 98.7 and 99.3%. Interference patterns
for pin-holes spaced 1, 2, and 3 imn apart and the intensity distribution of inter-
ference fringes were obtained. Analysis of the interference patterns showed, in
principle, that the degree of coherence of the laser radiation varied in differen--
parts of the laser beam and greatly decreased in the direction opposite to the
geometrical axis of the beam. The degree of coherence of the laser beam depends

greatly on the mode exhibited by the laser. It was concluded that the la5er beam
was 11almost coherent" throughout its entire cross section and that a greater degree
of coherence can be obtained for some modes. Comparison of the flux-density of a
black-body radiation Ws and the flux-density of an "almost coherent" radiation beam
W shows that W - (0.16 A) 2W.. For a laser beam at A - 6328 X the ratio W 1W is
P 0 p p s
more than 101 times greater than for black-body radiation. Orig. art. has:

ABSTRACT: Some theoretical and experimental studies correlate
catalytic properties of semiconductors with their
elec conductivities. In the authors' opinion, it is
more expedient to correlate semiconductor catalytic
activity not with conductivity but with surface
electronic state, characterized by the value of
contact potential, which depends directly on the
surface charge.
In order to study the changes in contact potential
values, the oxidation reaction of CO on the catalyzer
cupric oxide was used. The contact potential
