ABSTRACT: The results of investigations by Leningrad rneiallurgists in
the theory of crystalli7ation and the mechanism of the origin of
various types of inhomogeneities in steel ingots are set forth;
new types of ingots for forging and rolling, designed on the
basis thereof, are described. Data on the employment of spec-
ialized forging ingots with smaller shrinkage heads,without
shrinkage head, and with greater taper (10-12%), and on the
use of hollow ingots, are presented.

ABSTRACT: X-ray investigation of the zones of accommodation
shows a lattice orientation which is different to that in-
neighbouring parts of the crystal and shows a fine structure
in the zones. This result confirms earlier conclusions on
the structure of the accomm-odat-_*Dn- region based on indirect
measurements by means of profilometer and interferometer. A
boundary layer with a strongly dist-orted structure has been
found between the main crystal and the zone of accommodation.
Annealing leads to the disappearance of both twinned layer and
disturbed boundary layer but the zone of accommodation itself
does not vanish showing that it has greater thermal stability.,
X-ray diffraction pictures were taken using a wide-angle X-ray
tube and provided a sophisticated method of measuring the angles
between regions slightly inclined to each other. Angles of
about 301 had to be *measured.

TEXT: The study of twinned layers with dimensions 5 to 20 It in
single crystals of antimony has shown that annealing at 600 C
(for less than 5 hours) leads to the establishment of mono-
crystallinity in the specimen. The twin boundaries and the glide
steps are the.place where the most intense thermal etching occurs.
edge dislocations have been discovered both in the parent crystal
and in the twinned part. The dislocation lines lie in the 11I
plane. The Ill planes in antimony are the directions of the
principal cleavage. The crystals of antimony were obtained, after
preliminary zone refining, by the Shubnikov-Obreimov method.
Specimens were in the form of plates 2-3 mm thick and 10-12'mm
in diameter. They were prepared by cleaving the crystal which had
been grown. The defdrmation produced in this process gave rise
to the twinned layers mentioned. The examination was carried out

TEXT: It is found that in calcite a twin boundary not
.containing dislocations is made visible by selective etching
although the intensity of etching is significantly less than the
intensity of etching at dislocations. The existence of incoherent
twin boundaries containing dislocations has been experimentally
shown. In the crystal in the twinning process complete
dislocations are formed. The twins were produced by Garber's
method (Ref.5). Twin layers were studied on the face of the
crystal not forming steps on twinning, i.e. 100 or 010. The twin
plane could be indexed as 110 with the boundaries of the twinned
layers parallel to

]ABSTRACT: The autbors-hav studied the interaction of dislocations in zinc a
calcite crystals. A high density qf twinning dislocations and their paired correla~
Jtives,4m the neighboring edges of fine twin layers in calcite have been detected ?
It has been found that the stress necessary to shift the edge of all
ithin twin layer (less then ljj.) is much greater than that necessary to move the
itrdn edge of a thicker layer. Different kinds of pile-ups of twinning dislocations
.!were observed experimentally at the edges of twin layers. It has been shovm that
ithe distribution pattern of dislocations in these pile-ups is determined by the typ,
of_deposit. Experiments have also proved that the reglion of acconrmdation is'
repelled from the twin bDundary in .zinc crystals (because of the interaction 'of
1tvvinning and unit dislocations. It has been shorm that the lack of agreement be-

transformer. The thermocouple 3 is connected over the terminals 4 and 5
with aJlATP-1 (LATR-1) transformer. The hot junction of thermocouple 3 is
in'troduced in the notches of needle 1. Th:~ temperature of the needle and
of the thermocouple wires should be slightly higher than the melting tem-
perature of caprone. Spring 6 serves for tightening the thermocouple
wiree during adjusting and heating. After heating the needle and wires,
the bearing 7P to which the thermocouple is to be attached, is approached
to the hot junction. Under the action of its own weight, the bearing 7
shifts downward until touching the stage 8. The hot junction of the
thermocoupl-, is adjusted to the required depth of the bearing. The heating
of the needle and of the thermooouple is interrupted, and the wires are

removed from the terminals. The needle is heated and removed from the
bearing 7. The depth of adjustment depends on the table height which is
controlled by means of the nuts 9. The device described was used for
attaching a copper-constantan thermocouple to slide bearings of 48 mm
diameter, 3 mm wall thickness, and 40 mm width. The distance between the
depth of adjustment and the sliding surface was 0.1 mm. At sliding veloc-
ities up to 2 m/sec, caprone starts melting at ^025 - 1300C. At a sliding
velocity of >2 m/sec and a load of >75 kg/cm2, a jumplike increase of the
bearing temperature was observed as from 100 - 1050C, and the bearings
became useless. Maximum working temperature of caprone bearings is 100
1100C. There is I figure.

TITLE: Effect of meteor streams on the electrical field of the a!Mqjphere
SOURCE: AN SS3R. Izvestiya. Fizika atmosfery i okeana, v. 2, no. 3, 1966, 316-319
TOPIC TAGS: meteor, atmospheric electricity, electric field
ABSTRACT: Data on measurements of the electrical field of the atmosphere enabled thoautl=4
to study the effect of meteor streams on this field. The results of measurements of nine geo-
physical stations were used. The data on the electrical field of the atmosphere were analyzed i
by calculating the mean diurnal and mean monthly values of the field from the data of each geo-!!
physical station. These values were averaged for the three years of observations 0957-1959).
Then the variations of the field, i.e., the differences between the mean diurnal and mean months
ly values, were calculated. The calculated values and the change in the number of meteors for
all three streams (Perseid, Geminid, and Quadrantid) were compared. The comparison readi-
ly showed that the Perseid meteors did not affect the electrical field of the atmosphere. An

increase of the field during the passage of meteors was noted only for the more powerful
streams, such as Geminid and Quadrantid. However, the dispersion of the data did not permit
considering this conclusion sufficiently reliable. Therefore the correlation method of analyz-
ing the experimental data was used to elicit the assumed relation between the changes of the
electrical field and the number of meteors. The confidence interval was also calculated for
each stream. The correlation coefficient-stream intensity curve, for which the 10-Min value
of the number of meteors was taken, showed that for the most powerful streams the correla-
tion coefficients had essentially positive value. Thus, statistical analysis of the results of
the measurements showed with sufficient reliability that powerful meteor streams affect the
electrical field of the atmosphere at the level of the earth. A detailed study of the relation-
ship between these two phenomena and an explanation of the mechanism of this relation is
needed for the final solution of this problem. Orig. art. has: I table and 3 figures.

device is actually a capacitance bridge which compares the under-test
capacitor in one arm with a staadard capacitor in the other. A phase-sereitive
