ABSTRACT: In this paper, the author discusses the connection be-
tween the space change in the velocity of propagation
of elastic 1.-iaves and the geological structure of the
Forecarpathian Sag. He bases his statements on the
data of a seismic sounding conducted in 45 boreholes
during 1948-1958 by the Western Ukrainian Geophysical
Office. The study of all seismic sounding material
and the use of all data of laboratory measurings of
the velocities of elastic waves and of the porosity
on rock samples permitted a more grounded study of the
analysis of the space change of velocities and the
Card 1/3 establishment of the geological nature of these changes.

On Certain Regularities in Var'-ation of the Velocity of Propagation
of Elastic Waves in the Forecarpathian Sag
It has been found out that the velocity depends chiefly
on the degree of densification of the rocks, which is
controlled by the porosity in its widest meaning. As
shown by graph Nr 1, the velocity in younger deposits
increases with depth more than in the older ones,
which also makes apparent that the porosity of these
younger deposits is relatively larger. Thus, the
change in velocity along the vertical is connected with
the effect of the static loading, the change along the
horizontal - with tangential forces. The paper also
presents a scheme (see drawing Nr 3) for the chan-e in
average velocity at a depth of 1,000 meters, which
shows the connection of'v with the basic tectonic ele-
ments and individual structures of the sag. Conse-
quently, it has been established that the general na-
ture of the space change in the velocity of elastic
waves was formed under the effect of the same factors
Card 2/3 which caused the formation of the present tectonics

,Abstract; The varieties of silex were studied and compared with silex
from Belgian Congo. A.,, far as the wear due to attrition is
concerned, nearly all the varieties of silex are not worse
than that from Congo, whinh makes it possible to use them in
millz, as well as abrasives. Blocks of large dimensions and
without fissures can bp used for making rollers and mill bot-
toms in view of their great strength.

Abstract The milling of anthracite culm requires about 30 per
cent of all power supplied for the needs of the plant.
The article describes tests made with venting light
particles of pulverized culm returned from the separa-
tor and milled In ball mills. A detailed description
of the venting installation tested is given, and all
additional devices and Improvements are enumerated. The
design of the separators was improved after these tests
and the production Increased 20%, while the needed amount
of electric power decreased 15.5%. Two tables and 4
diagrams are Included.

TITLE: The permissible residue on an 88 micron sieve for anthracite dust.
(0 dopustimom ostatke R88 dlya antratsitovoy pyli)
PMIODICAL: Teploenergetika, 1958, No.3. pp. 29-33 (USSR)
ABSTRACT: A disc type separator, illustrated in rig.1, which intended to winncw
the fine dust from the material returned from the main separator, was
tested in 1955-56 on the drum-type ball mill 287/470 of it Igiar'kov
Power Station. The material returned from the main separator(type
OKK 6) 3.3 metres diameter, and passes on to the rotating disc from
which it is thrown by centrifugal force when the smaller particles
are picked up by a flow of air and the larger particles are trapped.
In testing the separator about 100 tasts were made. The variables
were: flows of material and hot air, and disc speed. With dust of
the required fineness IR88 - 7%) the output of the separator was
varied from 1.0 - 3.5 tons/hour whilst the :low of material ranged
from 6.5 - 18 t-is/hour. A formula is given to define the coefficient
of disperseness of the dust which is determined from the total residue
on two sieves, usually 88 and 200 microns. Differentiation of the
equation for the granular characteristics gives a new functional
Card 1/3 relationship of the percentage distribution of dust particles of
different sizes. In a drum type ball mill the finished dust is

usually of low quality with considerable over-willing which is one of
the main causes of low milling efficiency in these mills. The
quality of the dust can be Improved by using better designs of main
separators and by using secondary separators. The quality of the
dust winnowed in disc sepa.ators is characterised by the figures
given in Table 1. The authracite dust is of high quality and leaves
very small residuca on the course sieves. By using these separators
in the system of a drum type ball mill it is possible to improve the
separation effe-et, to improve the quality of the dust and to
increase the output of the mill. Total mechanical zion-combustion of
the fuel can be calculated by eummating mechanical non-combustion
for fractions of different grain size according to formula 7 of the
paper. For the case when the particle grain size of/50.5 microns
is completely burned, liable 2 gives the remults of calculations of
mechanical non-combustion of fuel by the procedure described in the
article and for the same case Fig.3. gives curves of fractional
mechanical non-comLastion. Vilion the quality of the dust is improved
the proportion of large particles in it is decreased. It may,
therefore, be possible to increase the average coarseness of the dust
burned, which will give a general increase in the mill output.
However, theoretical calculations show that in anthracite dust most
of the mechanical non-combustion occurs not on the coarse fraction
Card 2/3 but on the medium sized ones, the absolute content of which in the

Die permissible residue on an 88 micron sieve for anthracite dust. 96-3-8/26
dust is increased. Therefore, on improving the structural
composition of 'he dust (makilig it more uniform), the sieve residue
should be reduced, particularly Aen the initial mechanical ui.n-
combustion is high. If the quality of the dust is improved the
residue on an b8 micron sieve can only be _`ncreased if the mechanical
non-combustion is very 5mall. In this connection, Fig.4. (rives
graphs of the relationship between mechanical ron-combustion and
particle size for grains of anthracite dust of different sizes that
are fully consumed in the furnace and Fig.5. gives the relationship
betreen mechanical non-combustion of the fuel, and the fincrics.3 (4

TEXT: The aim of this 4ork-was to investigate whether it
would be possible to correct the radial variation in the magnetic
field by placing current-carrying conductors directly on the pole
faces. Detailed experimental studies have shown that if t1he
distance between the turns of the pole-face~coils is made varlia .ble
and the current through the coils is made-to increase linearly
at given radial distances, then it is possible (a) to incrensv
the intensity of the focusing magnetic field by about 20%
(typically from 9-10 kOe to 12-13 kOe) and (b) to correct the
nonlintar saturation effects. In the particular case irjvesti~ated
it was desired to produce a design field of the form

ABSTRACT: The new mechanized production line consists of an 80 m hy-
draulic conveyor, an lnclinqd worm conveyor for discharging
beets into the washing trough and 2 conveyors (1 horizontal
and I inclined) transmitting the beets to the boiling in-
stallation. The capacity of this outfit Is 80 tons of beets
per day. For the sake of fodder this plent processes and dis-
tills daily a mixture of 45 tons of beet, 24 tons of grain and
11 tons of molasses. The plant has processed up to the pre-
sent 4,000 tons of beet and it was found that beet which was
harvested 3 months prior to procossing requires no cutting up.
Simultaneous processing of beet and grain needs no overdosing
of malt, which remains to be 14% of the weight of starch. The
ready mash passes through the host exchanger to the fermenter.

TITLEt The 3ensitivity of hypovatalaBe guinea pigs to radiation
FEIRJODICAL; liatiobiologiya, v. 19 no. 4~ 1961, 555-558
TEXT! A stmej was made of the signifieftuce of the catalase reaction
and the significance of water-soluble peroxides in the pathogenesis of
acute radiation sickness. The study -was made possible by the fact that
Ra4Vq (Ref. 4~ Izv. in-tn. aravn. patol. zhivotnykb, 4, 1359 1958) dis-
covered guinea pigs whose blood catalase activity was approximately 30
times lower than normal. The tissues of these animals were also poor in
catalase, The aim of the experiment was to determine whether hypo-
eatalase guinea pigs were more sensitive to radioactivity then are normal
guinea pigri. The animals were exposed to X-ray irradiation in a dose
of 500 r at an intensity of 68.3 r/min. Clinical and biochemical exami-
nation showed that the course of radiation sickness in the hypocatalase
guin"a pigs was no graver than in normal animals. This showed that the

extent of catalan-4 activity has no effect on the course of acute radia-
tion sickness. These findings contradict those of P. Bonnot-Warry and
W. Frilley (Ref. 7r C. r. Acad. acl., 24009 1944) who found that intra,
abdovinal Injection of cattlase preparations lengt-bened the life of
irradiated animals. At the same timeg the first stage of sent* radia-
tion sickness was milder in the "catalass anisnals than In the normai
ones. This may be due to the formation of lesser quantities of lipo-
soluble peroxides in the hypocatalase guinea pigs immediately after
irradiation. The fivpocatalase guinea pigs differed constitutionally
from normal animals in that their tissues have greater dehydraso activity
and stronger glycolytic powers. The authors attribut& the milder course
of acute radiation sickness to these features of tissue respiration.
These features. howe-ver, did not prevent the death of the hypoestalase
animals on the Oth day after irradiation. In addition to ono of the
primary reactions, connected with the accumulation of lipo-soluble
peroxides, some other reaction must develop after irradiation in both
groups of animals, leading to their almost simultaneous death. The
authors have no data on this reaction. There are 2 figures, I table
