various diagrams expressing the effect of the Initial
height of the catalyst layer and of the apparatus
diameter on the heat transfer process, the effect of
Re = w*d on the heat exchange process, and the effect
Fr on the heat exchange process. The last diagram
also gave numerical values of Fr which made possible
the determination of the optima velocities of the
air for the investigated catalyst in laminar and
turbulent flow; the respective equations are (5) and

TITLE., Study of the ammonia synthesis in a suspended catalyst
layer
PERIODICAL: Zhurnal prikladnoy khimii, v, 35, no. 1, 1962, 37-42
TEXT: The authors studied NH 3 synthesis using a suspended layer
of activated Fe catalyst (type PK-/I(GK-1)) with an average par-
ticle diameter of 0.18 mm. The temperature dependence of the reac-
tion rate was found to conform to the Arrhenius equation and the
activation energy of the catalyst was calculated to be 41,000 kcal/
kg-mole., which is in agreement with results obtained by other wor-
kers. At pressures of 100, 200 and 300 atm., and over the tempera-
ture range studied (400 - 5600C) the reaction rate depended consi-
derably on the grain size of the catalyst. The linear rate of gas
flow also affected the degree of uniformity of mixing the gaseous
and fluidized catalyst phases and, ac-cordingly, the reaction rates.

reduces the required effort by three times. Strip 393 mm wide is fed into
tile guides (17) (see Fig. 1) to the limit edges on the linings (3) spaced
11 mm. from the center line of the first row of punches and in line with
the rear side of the knives (Fig. 3). The first press stroke punches two
hole: rows A and A, (13-75*mm apart), and the knives trim, the strip produc-
ing 5.5 mm wide protruding edges on both sides. When the punches rise, the
strip moves on again to the limit edges (i.e., 5.5 mm) and thrusts against
them. The second stroke punches the hole rows Eand 61, the third makes
the ro-as B and Bl, then rFl,.4 ~'4 1, EEl and so on. The die is produced by
the following procedure. A preliminary machined bed die blank is hardened
and tempered to a hardness of RC 60-62, then annealed, then fini3h-planed,
Preliminarily ground, drilled, re'-,med and mLLchined to fin,il dimensions with
an allowance left for final grinding. Th~--n follows the final heat treat-
ment --nd final plane grinding. The finished bed die must be used as jig
for drillin6r and re-amin,~~ tirie punch hcldt!r and the stripper, for this is
the only way to make the holes and punches m'itch accurately. The high
productivity of these dies and high accuracy of work pay off the production
costs in a short time. They are recommended for maos-production. There
are 3 figures.

A13STRACT: . Alpha- aminobu tyryl ohol ine (ABC) exerts a eentral
action differing according to the site of application; It com-
binea competitively with cholinergic receptors of neurons. In
trophotropic structures where the cholinergic neurons are usu-
-ally excited by aerotonin, ABC blocks the cholinergic receptors
and thus produces an anticholinergic and antiserotonin action.
-In orgotrople atruotures, its action resembles that of acetyl-
choline in high concentrations. [Orig. art. in Eng.) [JPRS1

PERIODICAL: Dopovidi Akademii nauk Ukrains1koi RSR, 1958, Nr 8, pp 900-902
(USSR)
ABSTRACT: Thirty-eight helminthological examinations were carried out
on sheep carcasses in the highlands of the Crimea. All
animals proved to be infected by helminths. The lambs were
more intensely infected by helminths than the adult sheep.
On comparing the data obtained from helminth fauna in sheep
of the Crimea and the Ukrainian SSR Poleslye, the conclusion
was drawn that sheep in the Crimea are more intensely in-
fected by Trichostrongylus vitrinus, Trichocephalus ovis and
Dicrocoelium lanceatum, and less intensely by species of
the genera Haemonchus Ostertagia. In addition, Marshallagia
marshalli and Nematodirus oiratianus are found in the Crimea,
These are "southern" forms which are not encountered in the
Poleslye of the Ukrainian SSR. A particular menace for sheep
raised in the Crimean highlands Is presented by Dicrocela,
Nemnatodirus and pulmonary forms of Strongilata.

ABSTRACT: The article covers the result of investigations con-
ducted in order to illustrate the species and the pe-
culiarities of fauna formation of the cattle strongy-
lates in the forest-steppe area of the Ukrainskaya
SSR. For this purpose, 143 helminthologic incisions
on cattle and calves were made, and 70 complexes of
gastro-intestinal tracts were investigated. In con-
sequence of this investigation, a 100%,infection of
the cattle with helminths was stated. A particularly-
strong distribution and a large number of sixii cattle
strongylates as Ostertagia ostertagi, Trichostrongylus
axei, Cooperia oncophora, Cooperia punctata, NeraLo-
Card 1/3 dirus helvetianus and Haemonchus contoi-tus was noted.

Their number mostly did not exceed 200, with the ex-
ception of one species, the invasion int.-ensity of -.,,;hich
reached in one instance 500 specimen.. Other species
of stronCylates were seldom encountered. The exten-
sity of invasion, and the number of population, c.,ere to
a considerable extent dependent on the natu.-al condi-
tions of the region, and particularly on the condi-
tions of cattle feeding. It has also been stated that
strongylates settle in certain parts of the organs..
The seasonal changes in the population number of va-
rious strongylate species were not the same. According
to this, they may be divided into three separate groups.
The strongylate species and the intensity of infection

PERIODIUAL: Stal', 1957, No. 9, pp. 7r/2 - '/?8 (USSR).
ABSTRACT: The influence of top pressure v*riation from 0.6 to 1.1 atm.
on the operation of a iarge (1 386 m') blast furnace was investi-
gated. The profile of the furnace is shown in Fig.l. Character-
istics of burden materials and coke during the individual test
periods are given in Tables 1 and 2. OperatinE~ factors are given
in Table 3. Changes in the distribution of C02 along the throat
radios in Fig.2, the composition and temperatures of the rwi-
pheral and top gas in Fig.3, the pressure drop with the height
of the furnace in Fig.4, changes in the gas pressure along the
furnace throat radius in Irig.5. Changes in the length of tap
hole and furnace-operating indices during various testing periods
are given in Tables 4 and 5, respectively. On the basis of
experience gained, the following conclusions are drawn: an
increase of top pressure from 0.6 to 1.1 atm., contributes to
the development of the peripheral flow of gases. In such case,
Card 1/3a decrease on the coke charge or an increase in the proportion

Operation of a Blast Furnace with 1.1 atm. Top Pressure.
of direct (ore first) charges (with simultaneous dropping of the
whole charge) leads to an increase in amount of ore charged to
the periphery with a subsequent decrease in the peripheral flow.
Static pressure along the furnace height changes lineary. On
increasing pressure of gas in the throat fr5m 0.11 atm. to 0.46
atm. and blast volume from 1 400 to 3 400 m /min, the blast
pressure increased more than that of top gas, while the uniform
Irop of pressure along the heigfit of the furnace was preserved.
On increasing mean gas pressure in the furnace by an appropriate
increase in driving rate, the blast pressure increases to the
same extent as the pressure of gas in the throat. With a constant
blast volume, the pressure of gas in the stack increases to a
lesser degree than that in the throat. On transfer to a higher
top pressurB (1.1 atm.) the blast temperature can be increased
by 20 - 50 C and the driving rate increased by 2-6% (in comparison
with operating conditions of a top pressure 0.6 - 0.8 atm). The
operation of the furnace becomes smooth, but on decreasing top
pressure back to 0.6 - 0.8 atm., the smoothness of the operation
deteriorates. On increasing top pressure from 0.8 to 1.1 atm.,
the output of the furnace increased by 8.3% and the coke rate
decreased by ?.9%. On decreasing pressure from 1.1 atm. to
uard2/30.6 - 0.8 atm., the output of the furnace decreased by 5.0 - 9.3%

ABSTRACT: The steel was melted in a 40-kg induction furnace. Race earth
imetals (PM) (98% pure) were introduced in a 0.01-0.15% quantity 3 minutes
before tapping. Their reeidual contents, independent of the calculated
addition) amounted to 0-00)-0-010%- The combined or individual intro-
.duction of boron and REM into lKhl3M2BF Z-sic_7 steel increases its ductility
and crack resistant;a. Up to 0.004% boron increases these characteristics, i
but if it is more than 0-004% it decreases them. The addition of REM permits
the preservation of these high indicators of ductility in steel containing
:up to 0.010% B. The introduction of REM into stool without boron offers the
same effect as the best addition of boron. The high indicators of ductility
and crack resistance in this.case are obtained in the entire range of cal-
culated and residual concentrati6ns of REM iiivestigated. The individual
.effect of cerium, lanthanum, or yttrium on ductility was.not obseryedo.[JMSI-~'J

ABSTRACT: This is a description of a control system for a 300 Mw unit using an infQrm
computer which performs the functions of digital registration of parameters,
signalization of deviations, computation of technico-economic indices and checking
of parametern upon operator demands The computer, with 500 points of control,
performs interrogation of transducers to seek deviations of pdrameters no less often
than each 10 seconds. Each instrument on the control panel can carry the indications
of up to 40 transducers, greatly reducing the amount and. difficulty of reading the
control panel. When a signal light lighte'up to indicate deviation-of a constantly
monitored parwneter,, the light flashes and a sound signal ic heard. to attract the
attention of the operator. A block diagram of the computer is presented. The
computer uses a single-address instruction system. with 30 instructions in its
repertoire. Input rate for information is 200 numbers per secondl printout rate is
10 digits per second.. Orig. art. has: 2 figures and 2 tables. LJPRS1

TITLEs Study of oxygen depolarization of porous cathodes made from
metals of the chromium group
PERIODICAM Zhurnal fizicheakoy khimii, V. 35, no. 19 1961, 102-111
TEYTs The development of powder metallurgy made it possible to manufacture
sintered porous electrodes with a surface much larger than that of smooth
electrodes. Following a aeries of articles by X. W. Voronin (Refs. 13-16),
the author studied the behavior of sintered Cr, Mo, and W electrodes for
the purpose of a) accelerating the reduction of 02 at high current
densities; b) studying the cathodic process of 0 depolarization; c) study-

ing the possibility of obtaining H202' The experiments were made with the
apparatus shown in Fig. 1. The electrode to be tested (2) was placed in
electrolyzer (1). inlet tube (3) served for connecting reference elec-
trode (12) which was composed of HgO + 1 N NaOH for tests with alkaline

solutions, and of lie2so4 + 1 N H2so4 for teats with acid solutions. Inlet
tube (4) contained a thermometer. (5) is a tap for emptying the electro-
lyzeri ~6) is a platinum electrode 30 mm in diameter; (7) is a pressure
gauge; (6) is an outlet for air or 0 2; (9) is a regulating tap; (10) is an
inlet for air or 02; and (11) is a pressure gauge. The cithode space was
cooled with running water. Experiments were carried out in 1 11 NaOH or
H2SO4 at 170C. The electrodes were made from metal powder (grain size
5-60,%) and pressed onto a substrate of iron powder. 10-15~1o' of a 5%
gasoline solution of rubber was added as a binder. Porosity was increased
by adding (NH 4)2CO3* Optimum conditions were: pressure of 1200 kg/cm2,
sintering temperature of 8000C, and a duration of 4 hr (for Cr electrode);
2000 kg/cm2, 10000C, 4 hr (Mo electrode); and 3000 kg/cM2, 13000C, 7 hr
(W electrode). The diffusion coefficient D*, the coefficient me of
permeability to gas, and the porosity Vo were determined according to
V. A. Royter and G. P. Korneychuk. From this, the mean pore diameter dp
the number N of pores, and their length 1 were calculated. Table I gives

During the electrolysis, the electrode was oxidized and covered with
hydratesq which resulted in a decrease of the pore diameter. The number of
"blind passages" increased due to corrosion. In the case of Cr, the
reduction rate of 0 2 was 250-280 ma/cm2. In the case of Mo, there was no
liberation of hydrogen even at 400 ma/ cm . At commercial current densities
70-80 ma/cm 2), the cathode potential was lowered by 0.885 v (Cr), 1.04 v
110)1 and 0.87 v (W). Small amounts of H 202 were formed on Cr and Wt

0.03 g1l on the Cr electrode when blowing air through the electrolyte
(current output, 2%), and 0.44 9/1 in alkaline solution. Blowing 0 2 through
alkaline solution increased the H 202 concentration to 1 j;/1 (current out-
put, 12%). No H 202 was formed on Mo. Commercial production of H 2 02is
thus impossible. However, drinking water can be purified with these small
amounts of H2 02' Fig. 6 shows the reduction rate of 0 2 as a function of
the NaOH concentration, and Pig. 7 shows dto. as a function of temperature.
Table 2 illustrates the influence of the partial pressure of 0 2' Depolari-
zation is improved by increasing the temperature, partial pressure, and
flow of the depolarizer. The differences in the course of 0 2 reduction on
the three electrodes studied is explained. On Cr and W, molecular 0 2 is
ionized at low current density. Electron addition to 0 2 leads to the
formation of H2 02' On 14o, this reaction is immediately followed by the
splitting of 02 into an 0- ion and an 0 atom. At high current density,
