Orig Pub Paliva, 1958) 38, No 2, 44-46.
Abstract In connection with the catalytic conversion (in an Ni-
catalyzer) of natural Gas in Bratislavia and Brno, the
necessity was revealed for drawinj; off from this Gas
the methyl- or ethy1mercaptan (M) ueed for bdorization
of gas iji the quantity 15-20 mg/nm3, inasmuch as M can
counteract the catalyzer. Isotherms of adsorption of,
M were found with activated carbon "Denzorbon" and by

Experimental studies showed that chlorpromazine and promethazine, administered
i. p. in dosages of20mg. per kg., afforded protection to rats irradiated with an LD
of X-rays.. The dose of X-rays used was 1,000 r. (162 kv.. 4 ma.. distance GO cm.,
exposure 87 min. ). The total number of rats was 72, including 32 controls, 32 re-
ceiving chlorpromazine and 8 receiving promethazine. Under these conditions, the
2 substances reduced mortality (evaluated 35 days after irradiation) from 89% to
50%. (XIV, 2)

TITLE: On the question of mechanisation of fuel supply and ash
removal in low power boilers. (K voprosu mekhanizatsii
toplivopodachi i shlalcoudaleniya kotlov maloy moshchnosti).
PERIODICAL: "Teploenergetikall (Thermal Power), Vol.4, No-5, May, 1957,
pp. 59-61 (U.S.S.R.)
ABSTRACT: The supply of fuel to small boiler houses can be
mechanised by the use of a vertical horizontal skip and
self-unloading bucket with a small crusher. This
system has been used for boiler houses with an output
of 6-12 tons of steam per hour. The fuel is delivered
'from the store to the boiler house by a mobile loader
type M4000. This loader consists of special automobile
on the back of which is mounted a lifting device with
a capacity of about 2.4 tons lifted to a height of 9 m.
On its way from the store to the boiler house the
loader passes onto a weigh-bridge to determine the weight
of fuel. A sectoral shutter is installed under the
crusher and it opens automatically as the bucket comes
underneath it. The loaded bucket then passes to the fuel
bunkers above the furnaces where it is tipped. When the
steam output is less than 6 tons per hour the auto-
loader can be fitted with a grab which takes fuel from
the store and lifts it directly to the bunker gallery
unloading it into the crusher bunker from which it goes
by gravity to a furnace. The loadercan deliver coal

On the question of mechanisation of fuel supply and ash
removal in low power boilers. (Cont.)
at the rate of 4.5 tons per hour from a store 150 m away.
This method of fuel delivery is very simple and cheap.
Simple ash removal systems are described. In the
first of these a channel filled with water is provided
directly under the furnaces forming a water shutter. The
ash is removed from this channel by dragging a scraper
along it with a winch and rope, the ash being deposited
in a small collecting sump. If it is necessary to repair
the scraper, screens can be fitted under the outlet
apertures of the furnace slag bunkers. In another
~installation a scraper type conveyor is installed.in the.,
water channel. A further arrangement employing low head
hydraulic ash washing is also briefly described. This
last method is different from the previous two in that
there are no wearing parts, it is simple to service and
the initial cost is low. 5 figures, no literature
references.

ABSTRACT: A survey of theory and experiments~related to ultra-sonic
cavitation. The following are covered: The theoxi3tical
strength of liquids and the hypothesis of stable nuclei. The
mechanism of transition from liquid to gaseous states due to
"critical nuclei" has been described by Frenkel
1) and
,
Zeldovich, 2); the behaviour of stable nuclei in an acoustical
field; the experimentally observed strength of the liquid under
the influence of an,ultra-,sonic field and, finally, the cavi-..,
. tation noise.
In conclusion, it is established that: the strength of the
liquid is determined mainly by stable gaseous nuclei; there
is no evidence as to the causes of their formation, though it
is thought that they are stabilised by organic skins; their
content in the liquid may be reduced by gas absorption,
increased pressure or decrease in temperature; their size
distribution in the liquid is not known; clearly, the probab-,
Card 1/2 ility of occurrence of a large, i.e. of a "weak" nucleus in the
regions of increased acoustical pressure, increases with the
volume increase of this region; it may also be due to the

increase of the total volume of the liquid, with a stream in
it. Tearing off of the liquid from the surface of a solid
with bad wetting properties may distort the strength of the.
liquid at that spot. In an acoustical.field, the stable nuclei
may move into regions of higher acoustical pressure or increase
,their volume as a result.of coagulation and,:possibly, of
diffusion of the dissolved gas during the expa3isiba-a. phase. At
higher frequencii~s only small diameter, i.e. more stable nuclei
can undergo cavitation. The above determine the main factors
influencing the experimentally-observed strength of liquids.
These factors are: presence of stable nuclei, volume of the
region of increased pressure, sound frequency and time of
sound irradiation.
In most experiments, the relative influence of one factor,
upon others was not adequately controlled. In the main, only
qudlitative data of influence of various factors-(d.g.,
viscosity, etc.) on the observed strength are known, with the
possible exception of the influence of gas content. Thei-e is:''
enough evidence about the cavitation noise that its level
could serve as means of measuring the intensity of shocks
during the collapse of cavitational strata. Numerical evalu-
ations show that this intensity should increase with decreasing

TITLE: The Electroacoustic Efficiency of Spark Discharges

PERIODICAL: Doklady Akademii Nauk SSSR, 1958, Vol, 118, Nr 4,
pp. 683-686 (USSR)
ABSTRACT: The present paper attempts to determine data on the
electroacoustic efficiency ofa discharge subject to
variousconditions, which are determined by the length of
the discharge gap, the amount of capacity discharged and
the electric potential. The circuit diagram of this device
is illustrated by a figure. This circuit permits a
discharge at one gap (which is described here) and the
simultaneous diac'.,arge at several gaps. The generation of,
the discharge is shortly discussed. A diagram represents
the time.characteristics of the amperage I(t) and of the
potential V(t) during the discharge of a capacity of

(at a potential V 30 kV) across different spark gaps.
These characteristics show the following: The generation
of an auxiliary spark in the air-gap guarantees an
increase of the potential across the spark gap to 30 kV
during fractions of a microsecond. Afterwards the potential
remains almost constant during a few microseconds and a
weak current passes through the spark gap. The duration
of this period varies from experiment to experiment and on
the avarage decreases on a decrease of the spark gap. This
period terminates with a potential jump, which fact speaks
in favour of the breakdown of the spark gap. The shorter
the spark gap, the lower the potential drop. After the
jump.point the potential slowly decreases, the current curve,
however, forms a peak. The acoustic field of the spark was
determined at a distance of R = 100 cm from the center of the
spark gap. Some oscillographs are given here. The electro
acoustic impulse was here defined to be the ratio between
(energy of the pulse with positive pressure / the energy
stored in the condenser). A formula is written down for the.
total energy of the impulse. The efficiency of.the trans-

acoustic energy decreases at a decrease of the spark gap,
that is to say, independent of the fact, whether C and V
remain constant or wether C is increased and V decreased.
The efficiency decreases also, if the length of the spark
gap remains constant, when the supply of electric energy
is increased by an increase of C at constant V. The
transition of energy from its electric to its acous.tic form
in a spark discharge in water is proceeding most efficiently
(with an electroacoustic efficiency of up to 30 %) in
discharges with long sparks.

ABSTRACT: An approximate energy balance per unit length of the channel is written out
for moderate-current discharges, when magnetic forces can be neglected., in the form
ds i d
+ PO N (t),
P, 7t dt
The channel pressure pk entering into this equation can be expressed in terms of the
channel radius R by solving the hydrodynamic problem involving the expansion of,the-
cylinder in the liquid in the acoustic approximation. The net result is a system of
equations describing the expansion of the channel from a known dependence of the ener-
gy release on the time per unit channel length (normalized to unity). By numerically
solving this equation and by regarding the discharge channel as an aggregate of point

sources, an expression is obtained for the energy of the compression pulse. 7he re-
Isults:of the calculations are compared with experimental data obtained by measuring
the discharge current, the electrode-gap voltage, the channel radius, and the pressure
in-the compression pulse. The theoretical results differed noticeably from the experi
mental ones in the case of large chann'el expansion rates. This difference is attri-
buted to nonlinear effects,"which are not taken into account in the equation, and
possible deviations of the channel form from the assumed one in the case of large
expansion rates. The authors thank N. G. Kozhelupova for help with the calculations.

TITLE: Production of caesium carbonate from pollucite-
concentrate
PERIODICAL: Tsvetnyye metally, 1961, No-5, pp. 55-57
TEXT: A possible source of caesium salts are pollucite-
spodumene concentrates. The object of the present investigation
was to study the possibilities of producing caesium carbonate in
this way with lithium as a by-product. Experiments were first made
in which pollucite, spodumene and their mixtures were treated in a
20-11tre autoclave. For pollucite leaching thebest conditions
were: 3 mols Ca(OH)2 per mol Si02, solid:liquid ratio 1:$,
temperature 220 OC, pressure 20.atm; but the stirring rate of
25 rev/min was insufficient and a horizontal ball-loaded rotating
autoclave would have been preferable.. Spodumene had to be
converted to the beta form by roasting before leaching. Artificial
concentrate was p .roduced by mixing pollucite with alpha-spodumene
(2:1) and calcining at 1000 OC and leaching with a higher stirring

rate of 110 rev/min. From the collective.concentrates containing
13.80% Cs20 and 2*70% Li20 the recovery of lithium and caesium
into the solution was 88.3 and 88.1%, respectively. if
concentrates are not roasted there is selective leaching of
caesium; lithium can then be recovered from the sludge at works
treating spodumene by the lime method Experiments were carried
out on treatment of solutions. After conversion to alums and four
recrystallizations the following degree of contamination of the
caesium was obtained: 9 9. 5% Cs, 0. 2, Rb, 0. 1 Na, 0. 2 K, 0. 0 Li.
To produce one ton of caesium carbonate with the 73% recovery
expected of the method requires 7.4 tons of pollucite concentrate,.
15.6 slaked lime, 6.5 sulphuric acid (monohydrate), 4.6 aluminium
sulphate, 0.5 anhydrous barium hydroxide and 260 m3 of carbon
dioxide. the authors consider that with recovery of caesium from
the mother liquor and a better design of auto'clave, 87% recovery
should be possible. ~The method developed has the advantage Iof not
requiring pure, scarce or expensive material, it yields products
of any purity up to chemicalreagent standard, and can easily be
-switched from the production of-caesium carbonate to yield any
other caesium salts. There is I table.

(USSR)
ABSTRACT: Investigations of the state of stress in damaged parts of in-
dustrial devices for high pressure were carried out by the
tensiometric method.For the determination of deformations on
the inner surfaces it was necessary to seal the transmitters
against the action of water at high pressure (400-900 atm).
The carbinol paste prepared for this purpose at the NIIKhIMMASh
(Ref 1) proved to be inadequate. Various sealing media were
tested (Table) such as bakelite varnish, silicon nitroglyphtal
glue.,192-T, bitumen varnish, nitro lacquer, carbinol paste,
perchlorovinyl paste, technical vaseline-paraffin mixtures,, and,
"Pushsalo"). The sealing qualities were tested by means of the
transmitter of the type ET-1, and it was found that the two
last-mentioned substances effect the best sealing. As the out-
let of the transmitters had to be altered also for tests to be

ABSTRACT; Changes in the technology of smelting 38KhlfYuA steel
since the start of its production in 1952, are outlined.
The main points in the smelting technology used at
present: a) a preliminary deoxidation of the bath with
pig iron after the end of the oxidising period; at the
beginning of refining,the bath is deoxidised with a
mixture of silicomanganese and 75% ferrosilicon in
lumps; b) addition of ferrochromium at the beginning of
refining; c) diffusion deoxidation with coke and
ferrosilicon during 20 minutes; d) shortening ofthe
reducing period to 80 minutes (instead of 120 to 1.50
minutes in the previous technology) metal temperature
before casting 1600 to 16200C in the ladle 1575 to 1590"'C-.
Despite improvements in the smelting technology, the

this type of steel are described: 1) Spot segregation

sulphur and phosphorus; the appearance of the defect is

~appears as lamination in the form of dark thread. No
changes in structure in the zone of the defect was
noticed, non-metallic inclusions are absent. Studies of
longitudinal cross sections of ingots (Fig 2) ind�cated
that the defect is associated with insufficient feeding
of the ingot during its solidification. 3) Cracks
usually situated in the central part of macrotemplets
(Fig 3). The defect was found to be caused by too early
transportation of ingot bogies after teeming (40 minutes).
