to include tanks of both spherical and conical shapes.
Natural frequencies and damping coefficients were determined
from the fomulae:

for cones, where r 0 is the radius of the free surface and
r0 is the radius of spheres. The dependence of C I and C 2
in spheres, on relative depth is shcwn in Figs. 14 and 15-
For cones the variation of C 1 and C 2 with inclination
angle a is shown in Figs. 16 and 17~ The cone formulae
were obtained for fluid depths h > r 0 and for amplitudes of up

ABSTRACT: In the process oX hydraulic breaking up of an oil bearing
stratum sand penetrates into the cracks which form in the
rocks and the peaetrated sand prevents the closing
together of these rocks when the liquid pressure is
reduced. Until the sand reaches the crack it has to
travel a considerable distance along the vertical tube.
Therefore, for selecting a rational technology of the
process of breal:ing up a stratum it is important to know
the hydro-mechanical picture of motion of a mixture of
liquid with sand, both along the crack and in the verti~zal
tube. Special experiments were carried out to verify
Cardl/2 whether available relations are applicable for such

in the Crack During Hydraulic Fracture of an Oil Bearing Stratum
coarsely disperse suspensions as mixtures of liquid and
sand; the experimental set-up is shown diagrammatically
in the sketch, Fig.l. The basic liquid used in the
experiments was glycerine and for obtaining various
viscosities the 151yeerine was diluted with water;
furthermore, sulphite-alcohol distillery refuse was used,
which is frequently applied in the oil industry as a
liquid for breaking up strata. As sand, quartz sand
with the fractions 0.6-0.85 mm was used and in some of
the experiments sand of other fractions was used.
Curves calculated on the basis of the relations expressed
by Eqs.(2.1), (2.8) and (2.11) are plotted in the graph,
Fig.6; in the same graph the values determined in the
here described experiments are also plotted.
There are 6 figures and 1 Soviet reference.

adopted. The DDA-100!,' sprinkler (designed by the
VTITIGiT4) had given -~,cd tervice on the "'Pakhta-Aral"

Plant for producing defective and poor-quality sprtnk-
lers and other meliorative macninery. To help exiend
the use of watering equipment Dn cottcn farms intensi-
fied research on such equipment is required. The Uzbek-
skaya akademiya.sellskokhozyay~Btvennykh nauk (Uzbek
Academy of Agricultural Scienc-9s) should encourage
and equip the Uzbekskaya dozhd.?val'naya stantsiya
(Tjzbek Sprinkling Station) and organize a chain of sup-
porting centers to introduce watering equipment in the
Golodnaya 9tep' and Fhorezm region. A supporting cen-

The Session felt that the Tashi-rmash Plant should in-
crease its output of PT-O le-teling machines to co-
ver the needs of the cotton-growing regions, since
leveling greatly increaseethe officacy of sprinkling.
The Session also advises resea:?ch and practical work

ABSTRACT: Assume that three pairs of parallel electrodes of the same length are sym-
metrically die-posed between two parallel lines (screens) of arbitrary length. On the
screens and on the adjacent electrodes the given potential is ual, on the other elec-
trodes uuO. 17he problem of potential fieldi ktermin tion mathematically xeduces to
the solution of the taplace equation lb2u/axz 4 ;:/ay2 =0 (1) in the.unlimited
region, problem (1) is solved by the method of G.M. Polozhiy by reduction to an inter-
nal problem of Dirichlet in a rectangle, for the Poisson equation. Methodology for the
solution of (1) on the Ural-I computer is described. A ccmparatively simple formula
of summary representations for field calculations is given; an algorithm for the solu-
tion of the emerging system of algebraic equations is constructed. Numeric results of

ABSTRACT: The authors consider an electron-optical system consisting of three pairs
of parallel electrodes, A potential U - 1 is applied to two pairs of electrodes of
equal length, and U - 0 on the third. The calculation of the field of such a system
reduces to the Dirichlet problem for the Poisson equation,&U - q(Xi, Y) in a rectangl
under the condition that U = 1 on the boundary of the rectangle, and q'(x, y) = 0
everywhere inside the rectangle, with the exception of the electrodes, on which
U(x) y) = u(x) y) is specified. Computation formulas are given to determine the
potential field and an algorithm is presented for the computer calculiLtion of the
coefficients of the system of algebraic equations. It is indicated that by using
the Adams-Stoermer extrapolation formula, and by assuming the potential field that
results ftom the calculation, it is possible to determine the flight -trajectory of
the electrons from the system of ordinary differential equations of -the form

71EXT: The author considers the prob
lems of quality of extra-
pcolation of a discrete function by discrete extrapolators with
the storage of the preceding values of both Input and ou,-tput
quantities and with linear extrapolation from the two preceding
values of these quantities. The analysis of the.extrapolation
quality is made on the basis of the formula for the output de-'
rived earlier by the author (W. 5: Voprosy aviatsionnoy avto-
Matixi I vychislitelnoy tekhniki, no. 2, KI GVFj 1962) and is
dependent on coefficients -r and p in this expression. The
coefficient Y determines the extent of the effect on the output
