Abstract ; The author describes the design and operation of a new
semi-automatic radial machine for making molds of sand
and resin for casting contour forms. The machine is
designed by the Scientific Research Institute of Found-
ing Machines of the Ministry of the Machine-Tool and
Instrument Industry (NIILITMASh), and is used for mass
production in foundry practice of ferrous and non-feZTOUB
metals. Three drawings, 1 cyclogram, I table and I graph.

TITLE: Identification of exchanged components from selsmograms of distant earthquakesi
SOURCE: AN SSSR. Izvestlya. Fizika Zemli, no. 99 1966# 67-92
TOPIC TAGS: seismic wave, seismography, earth crust, longitudinal wave., transverse
wave, stratigraphy
ABSTRAM" The identification of exchanged waves on the basis of amplitude to time ra-
tios of the wave components is discussed. The factoring, proposed in this paper, eli-
minates the background of longitudinal waves# thus widening the range of utilization
of the earthquake seismognams for the study of the lower earth crust. Because of the
low velocities of those walres, the seismograms have to be enlarged and redrawn. This
adds to the errors in interpretation. The resolution is limited by the periods of the
recorded oscillations and it in still necessary to identify the entry of each wave in-
to a new stratum. To identify the stratigraphic boundaries, the average velocities

TITLE: The Electrostatic Field of a Split Phase (Bundle Conductor)
(Elektroijtaticheskoye pole 'rasshcheplennoy fazy)
PERIODICAL: Elektrichestvo, 1958, Nr 9, pp 16 - 19 (USSR)
ABSTRACT: In investigating the electric properties of transmission
lines with split phases (bundle conductors), the author,
using bipolar coordinates, solves Laplace's equation
for plarte pwallol fields produced by one of the following
arrangements: 1 ) Two equally charged cylinders, 2) two
conduct.'Lng cylinderst 3) two equally charged cylinders
at the 'tips of an equilateral triangle, and an axis.
In 2), -the influence of the neighbor phases can be
taken into account, and in 3) the influence of the ground
(the mirror images of the conductors being assumed as axes).

ABSTRACT: The polymorphous lizard mentioned in the title is, in the
Xavkazskiy (Caucasian) part of its distribution area, divided
into 13 well characterized subdpecies, 6 of which occur in the
Armyanskaya SSR (Refs 1,2). In 1936 the researchers' attention
(Ref 3) was attracted by the paradoxical fact that one species,
L. 3axicola armeniaca Meh6ly which is widely distributed in
Armeniya (Armenia), has no males at all. The authorsconcerning
explained this by a biological anomaly, since in the other
subspecies of Kavkaz males occur frequently also. Besides the
"uvve mentioned subspecies, rostembekowi and dahli (Ref 2)
also have no males. The author collected these lizards during
an entire summer in order to explain this phenomenon, and he
Card 1/3 found only femules (Table 1). This was also the case with

Natural Parthenogenesis in Certain Subspecies of SOV/20-122-4-54/57
Rock Lizards, Lacerta Saxicola Everamann
lizards which natched from eggs in the laboratory (Table 2).
11o sperms could be found in the genital tracts of the mature
females of the three subspecies mentioned (swabs were
carried out by V. N. Kulikova, Institut tsitologii All SSR
Institute of Cytology AS UjSR). To check this three other
Armenian females subspecies were dissected, and normal
living sperms were found (Table 3). On the basis of this, the
author would like to consider as proven, that males are
lacking in the 3 Armenian subspecies of rock lizards mentioned
above. This was confirmed by obtaining progeny from known
unfertilized females. The paper is continued together with
V. N. Kulikova (see above). There are 3 tables and 3 references,
2 of which are Soviet.

young male, 448-mm-long, arrow-snake Psammophis lineolatus

The animal was found 600 km away from its nearest natural
habitat and under quite different conditions than this
snake usually has in Central Asia. The snake was given to

ABSTRACT*- The heat resistance of tissue in cold-blooded animals of

at five different temperatures from 44 to 49? Average results
are given in figure 1. This shows that the muscular tissuesof
each of the mentioned species are of a different resistance.
The whole curve characterizing Er. strauchilla resistancep

truth of the differences in the mentioned period shows that
heat resistance is higher in Er. pleakei than in Er. strauchii.
This difference corresponds to the temperature of the habitat
of these two speoieso Although they live in the same area,
their activity develops at different hours of the day. Figure
2 shows the number of lizards of the two species which mere
found at different times of the day. In spring (April to June)

the ground has been warmed thoroughly by the sun. When the

Er. pleakei not only likes heat better than Er. strauchii,
but also has a hig4er resistance to it. The differenoesin

ABSTRACT: The stability is investigated theoretically and
experimentally of a cylindrical shell of "medium" length
with non-deforming edges subjected simultaneously to
torques and normal pressure. In the theoretical
formulation it is assumed that the edges of a free thin
cylindrical shell are joined with absolutely rigid elements,
for instance, rings and it is assumed that there is no
displacement at one edge of the shell. The loading is
assumed to consist of a torque applied to the rigid elements
az)d a normal, internal or external, pressure equally
distributed along the entire shell. The stability problem

in practice the basic form is identical with td6 form of

It is assumed that the shell under consideration satisfies
the conditions expressed by Eq.(1.1.1)1 p.138. Experiments
show that the loss of stability in the elastic range with
the load under consideration is accompanied by the formation
of a largernumber of waves and this permits using

results were obtained by P. G. Burdin (see his

ABSTRACTs The present @aper solves the problem of the above mentioned
stability in the case of torBion. with sufficient internal
pressure. This shell is assumed to have an "average" lengthq
which term is defined. The edges of the shell are assumed to be
fastened in a hinge-like manner or to be embedded. The here
discussed results are a generalization of the corresponding
results derived in a previous paper by V. M. Darevskiy (Refs 1v2)
for an isotropic shell. As initial equations# the equations for
the equilibrium of the shell in consideration of their
deformation and the usual relations between the internal force
factors (silovoy faktor) and the deformations expressed by the
Card 1/3 displacements are used. If axial- , radial- f and shear stress

param6ter Ais defined by: 1) either the number n, a few times larger than the

the number of waves in'the peripheral direction, /J.2 - 14-1 - 2 Jr mR/l, m - 1, 2,
3) or the number n, equal to zero or 1. It is assumed that the shell edges are
hinged or stiffly restrained. Based on the conventional assumptions of the
elasticity theory, a system of linearized equations of the equilibrium of the
orthotrople cylindric shell is obtained; the equations are simplified further
on the assumption that the shell represents a membrane. This system is reduced
to one linear differential equation with partial derivatives of the eighth 4ynder
