ABSTRACT: Since about 50% of the coal requirRd by the.economic
districts of the Ural, including the Sverdlovsk,
Perm' and Chelyabinsk Oblast', are mined in Karagan-
da, Kuznetsk, Ekibastuz, Cher6mkhovo and Khakasiya,
the authors recommend exploiting the local peat
deposits as a boiler fuel. In the past, many methods
for using peat as a boiler
fuel have been tried, but.
e
these experiments failed, since an economic and
stable firing of,peat could not be achieved. Only
the pneumatic stokers of TsKTI, which were based on:
Card 1/6 the whirl principle of A.A. Shershnev, had some

success and to-ether with the shaft-mill method, they
found the most wide-spread application. The cyclone
stokers, suggested by Professor G.F. Knorre, are the
latest development in.this field. The shaft-mill
msthod has a heat liberation value of 150-103 kcal/
M3 hy while that of the TsKTI stoker is 120-10 kcal/
m h, which is relatively low and therefore large
stoker volumes are required. -In addition, soot traps
must be installed, since about 85% of the peat ash.
are carried out of the smokestacks with the first
method and almost 100% with the TsKTI-stoker. The
large stoker volumes and the soot traps of the pre-
sently used methods are not suitable for a large-
scale conversion of boiler stokers to use peat as
fuel. Therefore, only 2.09 million tons of peat
were mined in the Sverdlovsk Oblast', in 1957, while'
the annual output could be around 40-50 million
tons annually, since the peat deposits in this area
Card 2/6 alone are estimated at 4.5 billion tons. The Ural

peat is composed of small particles those having a
size of 3-4 mm amount to only 10-15 and its ash
content is 8.9-9%. The melting point of the ash
varies between 1050 and 1170 C. The moisture con-
tent changes annually; in 1956 it was 46.3%, while
it decreased in 1957 to 42%., Mining oAe ton of peat
costs presently 16-18 rubles, but this cost could be
reduced with large-scale'mining methods. For using
peat as boiler fuel on a large scale, the authors
recommend a cyclone stoker with liquid slag removal.
However, there are no publications available on data
for firing peat in cylone stokers. According to
data furnished by M.A. Nadzharov ~R`ef 57 for coal-
fueled cyclone stokers, the slag viscosity must not
exceed 250 poise at 14000C. Calculations showed
that with a 50% moisture content of the Deat, temper-
atures of only 1400-15000C could be obtatined at the 0
outlet of the cyclone stoker,,even if ho~ air of'400
Card 3/6 C was blown in, while theoretically 1640 0 were re-

quired. The authors had the opinion that such a
temperature would not provide a stable and continous
removal of the liquid slag. When burning peat in a
cyclone stoker with liquid slag removal, the main
problem is to provide a temperature in the combustion
chamber which exceeds the melting temperature of the
slag to a considerable degree. The authors perform-
ed the same calculations for peat with a moisture
content of 32-35% which showed that a-tempe .rature
of 1706-1733 C could be achieved when blowing in
air at 350-400 00. Figfire 1 shows the-graphical pre-
sentation of the calculation results. A footnote
says that the slag viscosities of various fuels are
under investigation at UP! - Urallskiy politekhni-
cheskiy institut imeni S.M. Kirova (Ural Pollytech-
nical Institute imeni S.M. Kirov). Based on the
theoretical calculations an experimental cyclone
stoker was built at UPI, as shown by figure 2. A
Card 4/6 fan was used, powered by a 5-0 Inv asynchronous motor,

which produced a pressure of 2,000 mm water column
at 3,000 m3/h air consumption. 0The air heater pro-*
vided temperatures of up to 500 C. The combustion
chamber of the cyclone stoker is shown by figure 3.
The peat used for the experiments was preliminarily
dried and had a moisture content of 15-20%, its ash
content was 11%,with 62-69% volatilematter. -Its
heat value was 3900-4100 kcal/kg. The peat was fed
into tfie cyclone-stokeE at a rate of 450 kg/h.at an
air temperature of ~50 C, whereby heat liberat' n

the cyclone stoker were 1500-1600 C while the surface,
temperature of the liquid slag flowing out of the
0
tap hole was 1380-1440 C. Pyrometer errors must be
taken into consideration, thus the actual temperatures
were somewhat higher. Based-on the positive results

approximating circuit is a L- circuit followed by a delay line and mixer combination to
simulate the multiple signal reflections which arise in such paths. A combination of these
circuits was used to construct a path simulation system. INTeasurements of the response of
this system using simple signals (t), u(t) cos v-10t, u(t) sin k-j and S (t) u (t)
sin as well as arbitrary pulses, showed a deviation of 5% or less from true values.
It was.concluded that the initial pulse form (at the antenna) is very imporLant and that small
changes in the iniUal pulse form can influence the final response very significantly. For
this reason, the transient characteristics of the antenna must be considered in detail when
computing the transient response of the ground wave propagation path. Orig. art. has;

pulses over a two-layer structure, considerable distortions were

ABSTRACT: The authors discuss experiments designed to determine the effects of
psychological factors such as the degree of signal significance on information processing i
by man in choice-making situations. The authors cite experiments conducted at the
Department of Psychilogy, MGU (Otdeleniye psikhologii MGU) under the supervision of
Prof. A. N. Leontlyev. The results of these experiments were published ("Voprosy
psikhologill.1 1962, No 6). Leontlyev studied the effect of the degree of signal significance
on reaction tixne as a function of the quantity of average information. Similar experiments'
were conducted in which selection reaction time as a function of the quantity of average

the mixture (II) was heated in vacuo to 5600C, it'formed 100-110 cm3
gaseous products per g of mikture ard about 6V smoke which burned in the air
on ignition. A liquid phase formed at the surfaces of the two mixtures
studied. The surface temperature was approximately 6400C in mixture II.

TITLE: Baryte processing in Czechoslovakia
PERIODICAL: Przemysk chemiczny, v. 40, no. 6, 19617 311-314
TEXT: Processing of the Slovak sideritic baryte is described.
Of the main Czechoslovakian deposits, the largest are found.at
Rudniany and these have, therefore? received greatest attention.
The Rudniany orelis a mixture of siderite,,baryll-e, tetrahedrite,
chalcopyrite, quartz and.shale. Intergrowth of the various min-
erals excludes the use of gravitational methods of separation-
into concentrates. The ore is of 2 kinds: (a) sideritic ore
containing 30% Fe, 10% BaS04', 10% Si027 0.15% cuy'O 03% Hg and
a graphite shale; and (b) ferrobaryte composed of 16% Fe and
50-70% BaSO The latter is free from graphite and yields a
high co cen rate suitable for bleaching. Refining of the sider-
n
itic ore has been worked out and consists of a magnetic separa-
tion followed by a series~of flotations. Sodium lauryl sulph-
o.nate (Syntopon CP paste)
used in laboratory experiments for-~

ss will come into operation upon
the baryte flotation. The proce
the completion of the newplant at the end ofthe 3rd-5-year plan..
Eventual attainment of 97,% BaS04 in the concentrate is expected.
Ferrobaryte will be refined intermittently as required by the,
same method and at the same plant, yielding a concentrate which
may then be bleached and processed into pigment. To meet critical
demand, flotation of ferrob6ryte was first carried out in 3 copper
refineries in 1956 and was later centralized in a single plant.
Composition of the concentrates obtained is tabulated. Fo-r flo-
tation, the ore must be crushed (70-80% below 200 mesh), suspen-
sion density should be 250-300 g/1, and 0.8 Kg,oleic acid, 1.2
Kg Syntonpon CP and 0.45 Kg water glass must be added per ton of.
ore. Further chemical processing.of the barytic concentrate in
1956 gave rise to a number of problems as the materials could not
be utilized directly due to the unfavorable chemical composition
and fineness; tl~us even direct reduction to BaS proved impossible
because of excessive (> 70.6 %) Fe2+ content. It was found that
at least 90% BaS04 and not more than 1.5% Si02 and 5.3% R20,3 were

needed for successful reduction. A baryte extraction plant was
opened on 1.7.1957 and continues production to the present day.
The chemical treatment processes are then 'described. The pro-
cesses are fairly costly due largely to acid corrosion of the,
equipment. On the chemical side, the yield of baryte concen-
trate is 0.02 - 0.06 t/hr/m3 of extraction vessel and requires
2'3 Kg of 100% H2SO1+ per Kg of Fe dissolved. The losses amount
to 5.4% during removal of siderite and a further 1.6% in fines.
Additiox~al losses include r,,3% during the reduction to BaS, as
dust. It is-estimated that 2000 Kg of pure concentrate .7--.re needed
for 1 t6n of BaS. Some of these losses may be avoided, e.g. by
more efficient dust catching or granulation of the reduction
mixture and general improvements are anticipated.in the future.
Methods of bleaching the flotatiQn concentrate with acidic wastes
from the production of titania white were evolved in 1956-58 for
ores containing no elemental C. Standards for such concentrates
are the same as for the reduction., A continuous bleaching pro.-
cess was devised in 1959 and will be put into operation in 1961,

employing the same equipment for both chemical refining and bleach-
ing. At present BaS production is carried out in the same equip-
ment as used for chemical refining. In the.latter, 1.5 t of
concentrate are treated with lm.3 of waste acid at 900C, for 1-2L
hours. In multistage flotation dark foam collects in the first
few tanks and light in the last.. The product s consist of a light
'suspension (-1800 g/1) and a dark foam containing 1-15% of baryte
concentrate. The suspension is filtered, washed, filtered again
and converted to BaS. The fines yield bleached baryte and pigment.
Concentrate collected by,the foam is reduced to BaS. Refinement
of baryte for the petroleum industry, by the removal of flotation
reagents and finer granulation, is now.being investigated. Large
scale production of baryte concentrates and of a wide range of
Ba. compounds is expected in the near future. There are 1 fiaure
and 2 tables.

TIM.* 100-Channel Amplitude Analyzer
PERIODICAL~ Jadern& energle, 1960. No. 5, P. 167-
=T: The 6s-tav jadern& fysiky (Institute of Nuclear Physics) built a
100-cbannel amplitude analyzer with a nickel-wire magnetostriction memory.* The,
apparatus is of cabinet design with power sources mounted in the lower half and
two vertically mounted drawers of the apparatus.properin the upper half. Radi
ation hitting the detector is converted to electrio pulses, whose amplitude cor-
responds with the energy of the radiation. The-analyzer directs these pulses
Into the individual channels according to their respective amplitudes. The ap-
paratue operates on the principle of amplitude-to-time conversion with pulses
being stored in a magnetostriction memory. The spectrum measured is indicated
on a screen in the binary system in the form of permanent bright spots. Ampli-
fied pulses are fed to the analyzer where they are,furLher amplified and shaped.
Subsequently, they pass through a gate to the comparator cirmit. Here their
amplitude iz compared to a linearly increasing, periodically repeating sawtooth

voltage. The result obtained is a time period defined by the starting point of
a sawtooth and the point of agreement. The pulse obtained is recorded in the
channel corresponding with the established time period. The number of-channels
is variable by a switch in 4 stages.(60. 80, 100, and 120 channels). The memory

rate of I Me. Additional measurements, e.g., with a two-crystal sum spectrome-

tegra.ted spectrum are extracted from -i independent output terminal. The read-

into groups of five, and by a transparent grating with numbers indicating the
