TITLFt: On one-Urcui of a Standard Parallel Arithmetic Unit
PERIODICAL- Sb. tr.,Vvchial. teentra. AN UkrSSR. 1958, No. 3, PP. 32-44
TEM, A detailed description is given of logical and structural circuits
of standard parallel arithmetic units. It is presumed that the developed standard
units will be employed extensively in a number of electronic automation systems.
The follovrng requirements had to be considered when designing the standard units:
universal jl,., *,y in performing arithmetic and logical operations, simplicity of the
logical c1rouits, reliability, high-speed action, low costs. The following points
were taken as fundamental parameters and characteristics of arithmetic elements:
binary computing system, fixed point, word length of 16-20 digits, 300 kc
synohroniz:Lng pulse frequency for the tube variant, 300 ke for the junction
transistor variant. The basic element of arithmetic units is the flip-flop
(see figuni), distinguishing itself by the absence of a differentiating circuit

describe the logical circuits of the register and the
adder. A juculiarity of the adder is the addition of numbers in two cycles and the
absence of itemory elements. The authors investigate the general circuit diagrams
of arithmeti-a units and also the structural circuit diagram of one digit of the
aritkunetio init. The suggested circuits ensure the execution of basic dperations
and possess the following special features: a) for multiplication and*division
operations, shift and addition are effected in different registers, which makes

it possible t: combine these actions and to reduce the overall time; b) there
are no shifts in the adder, which ensures an increase in operating frequency;
c) the absen:e of memory elements. An 8-digit model of an arithmetic unit with
an operating !requenvy of 200 ko has been developed, it performs 20,000 multipli-
oation operat:t)ns per second. Static flip-flops with 6H1Tr (6NlP) tubes and Pulse
- potential "tx7" gaten are used in the model. One digit of the unit contains
8 tubes, 40 d:))des and 22 pulse flip-flops. The authors briefly describe the
principles of tionstruotion of a single-program control machine. There are 8

TEXT: The authors describe the automation of the control and regulation
of the Bessemer process achieved after long experimental investigations
which were carried out by the Dneprodzerzhinekiy veoherniy metallurgiche-
skiy institut (Dneprodzerzhinsk Evening Institute of Metallurgy) and
the zavod im. Dzerzhinskogo (Works imeni Dzerzhinekiy). The latter two
establishments investigated the available nonautomatic oontrollingmeth-
,ode of the Bessemer process# and worked out now methods suitable for
automation on the basis of high-speed electron computers. A system hah
to be worked out by which it is possible to interrupt the blowing of

The authors describe the methods of determining this instant used on
the,basis of theoretical and practical investigations. This instant is
predicted on the basis of information received with the use of methods
of mathematical statisticso 'The information received by all methods for
the determination of the instant is taken into account. Work for the
automation of the Bessemer process was performed in two stages: First,,
the information apparatus was designed, mounted, and taken into opera-
tion at the Works imeni Dzerzhinskiyj it was automatically connected
with the transmitters# and automatically started and stoppe41 in the
second stage, a digital control machine was developed. This recording
digital apparatus was worked out by the Vychislitelinyy teentr AN USSR
(computation Center of the AS UkrSSR). It is described, and its mode
of operation is explained. The authors describe the operation condi-
tions of this plant, and its construction and principal elements. It
was installed at the Works imeni Dzershinakiy in March 1960. At present,
the data obtained from this plant are being evaluated mathematically
together with the data of chemical analyses, and a program for the con-
trolling machine is set up. There are 2 figures.

be of the same order ati in the Intei;ration of ordinary differential equations. The authors ex-
press their 1;ratitude to A. N. Shirygev for his formulation of the problem and discussion of
the results. OrIg. art. has: 30 formulas, 3 figures, 'ind I table.

ABUTRICT: The authors investigated several methods which are based
sither on the unsatitrated constitution of the acenaphthyleine
or on its intense yellow coloration without having obtained
satisfactory results. Finally a gr4vimetric method was
found which In characterized by the fact that acenaphthylone
forma a sparingly soluble polymer under the influence of
strong acids (sulfuric said with glacial acetic s.aid). Table 1
presents the determination results for mixtures of
aesnaphthylene and acenaphthens. The results which are not
quite precise can be corrected by means of a calibration
curve when strictly proceeding-according to the analysis
directions. Simpler is the calorimetric method in which the
aoenaphthylene is distilled rapidly in low absolute pressure
(in order to avoid-resinification) and investigated

TITLE: The Oxidation of Acenaphthene to Naphthalic Anhydride
PERIODICAL: Zhurnal prikladnoy khimii, 1959, Vol 32, Nr 5, pp, 1126-1132 (USSR)
ARSTRACT: The vapor-phaso oxidation of acenaphthene to naphthalio anhydride is
studied here. The oxidation was carried out by air at 320 - 4350C
over vanadium catalysts and manganese dioxide. Vanadium pentoxide as
catalyst produces a mixture of acenaphthilene with unreacted ace-
naphthene. At an increased air supply naphthalic anhydride may be
present to the maximum amount of 29%. The addition of potassium sul-
fate to the catalyst raises its activity and with the increase of the
temperature the yield of naphthalic anhydride rises sharply. Naph-
thalic anhydride is the principal product of the reaction, if the air
supply is sufficient. The oxidation of acenaphthene over manganese
peroxide leads to a yield of 28 - 30% acenaphthilene at 3250C. The
highest yield of naphthalic anhydride is obtained with a catalyst of
iron vanadate, with potassium sulfate at 350 - 3700C and a volume ratio
acenstphthene :: air - 1 : 100. The time of contact is 2.9 sea. The
Card 1/2 yield of anhydride Is 75 - 80% of the theoretical.

TEXTs In the present paper the author describe the possibility of an
oxidation by means of sodium bichroaate (at least of certain organic com-
pounds) in a solution of hydrochloric acids without the separation of
chlorine. In this cases tho concentration of hydrochloric acid in a certain
organio compound to be oxidizedv must not exceed a certain degrees and must
lie in a certain ratio to the amount of the biohromate used. This is shown
here for the oxidation of I-nitroacenaphthene. The oxidation of 4-nitro-
aoenaphthene in a modium. of sulfuric acid takes place very slowlyp and
gives rise to a low.yield. In a sodium containing hydrochloride, oxidation
takes place quickly and under easy conditionsp without resinification and
combustion. The yield of 4-nitronaphthalio acid was 80-65%. The amount of
hydroohloric.acid must not exceed 5 moles of hydrogen chloride per I sole
of sodium bichrozatoo while the concentration of hydrochloric acid must

ABSTRACT: Exper@ments were performed in order to investigate the
possibilities of producing single crystals with uniform longi-
tudinal and cross-sectional distribution of impurities by means
of pulling at a controlled rate as well as by pulling accompanied
by constant feeding of pure Ge into the melt. The raw poly-
crystalline material with a ? of 5-20 ohm/cm was purified by
means of zonal recrystallization under a vacuum of 10-4 mm
Hg, or in a stream of HZ, until it exhibited a ? of 50-n6o
Card 1/3 ohm/cm. A high-frequency heating apparatus with three

induction units moving back and forth was employed. It was found that single
Ge crystals, grown by the Chokhralskiy method from purified material with
a ? of 50-60 ohm/cm in conjunction with mixing of the melt by rotating the
crucible and the growing crystal, can achieve? and -rvalues of 60 ohm/cm
and 1000 JA sec, respectively; if the rotation is omitted from the growth pro-
cess, the ? and theC amount to 25-50 ohm/cm and 200-250 p sec, respect-
ively. The UVM-Z apparatus, employed in the process of pulling the crystal
under vacuum (10-4 mm Hg) in accordance with scheduled variations of the
rate of pulling, utilizes a hydraulic raising mechanism which provides a
smooth variation of the elevation rate from 0.05 to 8 mm/min in conjunction
with the rotation of the crucible and the growing crystal. The 9 value of
grown crystals 50 mm in diameter and 180 mm long deviated from the mean
value of rV40-60 ohrri/cm, at a length of 100-150 mm, by 8.9-9.3% and was
within the limits of error of measurement. It is pointed out that because of
variations in conditions of crystallization only macrouniformity in the distri-
bution of impurities can be achieved by this method. The variations were
eliminated in another device which was designed for a process in which the
pulling is accompanied by feeding of pure Ge into the melt. Prior to im-
mersion into the melt, the feed ingot passes through a heating unit (composed
of a quartz tube wound with W wire), while the ingot being pulled passes

through it water-cooled unit made of stainless steel. The process of pulLg
was carried out in an Ar atmosphere. The fact that the feed ingot and the
growing crystal, which may rotate, were placed excentrically with respect
to the axis of rotation of the crucible, contributed to a better mixing of the
melt contained in the crucible. It was found that the lonaitudinal q fluctua-
tions irk single cryfitals obtained by this method did not @xceed t576,
whereas in the case of a crystal produced in this apparatus without the em-
ployment of pure Ge the scatter amounted to � 24%. Studies of crystals
with a diameter of 50 mm have revealed that the ? was sufficiently uniform
throughout the cross Section of the crystal and that the diffusion-path length
of minority current carriers did not deviate by more than 10-15016. The
authors express the opinion that intensive cooling of the growing crystal,
which results in the achievement of a plane crystallization front, contributes
to uniform distribution of electrical properties throughout the cross section
of the crystal. Grown single crystals which exhibited nonuniform cross-
sectional distribution of were subjected to heat treatment in order to bring
about a redistribution of values; in the process the mean value of resistiv-
ity remained unaltered, while the diffus th length of the minority cur-
rent carriers increased somewhat. 1- =ium--Proces sing 2. Germanium--Crysi

TEXTs The problem in growing crystals for sleotrical
purposes is not now just one of purity but of distributing a
controlled impurity in a uniform way. Experimentally this is done
by making the crucible in the form of two communicating vessels
(Fig.1). Generally the inner vessel contains the impurity in the
desired concentration and the outer contains the material, e@zther
pure, or with a selected reduced concentration of impurity. The
connecting aperture is made so small that diffusion of the

impurity from the iniler vessel to the outer can be neglectedi the
flow in of new material thus takes place QLnlY when the crystal is
withdrawn from the mfilto The concentration of the imo.drity in
the inner vessel can thus be kept up by feeding it inio the outer.
Formulae are then derived relating the geometrital dimen3ions of
the inner and outer -ressels and a specimen caltuiat--on is given
for designing a crucible for growing an alloyed single @rry3ta_'.
If the distribution ,,)f impurity in the crystalline rod drawn oull.
of the crucible is to be non-uniform then this can be arranged by
making the tross-sectional area of the outer vessal vary
appropriately with depth,

ABSTMT: In this paper the authors presented the results of an investigation of
the concentration and temperature relationships of the surface tension of indium-
antimony system malts with the congruently malted chemical compound indium antimo-
nide. It was explained thae a correspondence exists' between the spatial points on
the structural diagram of the indium-antimony system and on the diagram surface
tens ion-compos ition. In siddition, experimental data was obtained on the surface
tension of melts.for which the composition does not strongly differ from the
stoichiometric melt of thoj Indium-antimonide compound, A diagram of the instrumaut

for determining the surface tension was presented. Results were presented in graphs.
The temperature relationship of the surface tension was studied as the following;
indium sat a temperature range of 200-8000C), antimony (at a temperature range of
650-800 C) and 26 alloys of the indium-antimony system at a temperature range of
550-700OC'. It was established that throughout the entire investigated temperature
range, antimony is surface active in relation to indium. It was shown that the
existence of an intermetaIlic compound in the indium-antimony system finds repre-
sentation in the isotherms of the surface tension in the malts of this system*

ABSTRACT: A description is presented of a combined setup for growing of single crys-
tals drawn from the melt and measuring the surface tension of the melt. Measurement of
the surface tension of a melt of InSb doped with Ge or Be has shown that the Be is
surface-active (it is adsorbed) while the Ge is surface-inactive (is not adsorbed) as
an additive. Single crystals and dendrites of InSb were drawn from melts doped with
germanium in the range 0.05 - 2.5 at.% and Be Ox24 - 0.25 at.%. With increasing Ge
concentration in the melt, the width of the dendrite ribbons decreased. No noticeable
influence of Ge on the growth of the single crystal was noted. Dendrites with large
Si content. could not be grown., for their growth stopped at 0.25 at.% Be. No morph-
ological differences were noted between single crystals grown from melts alloyed with
Be or Ge. The dependence of the supercooling of the InSb melt on the Ge or Be con-

2. 5 at 16 and with Se In the amount of 0. 0024-0. 25 at %6. An increase in the con-
centration of Ge in the M was accompanied by a decrease in the width of dendrite
strips. No particular effect of Ge on. the growth of C was noted. No success was
achieved In growing dendrites containing large amounts of Se, since at 0. 25 at %
of Se their growth ceases. No morphological differences were noted between C
grown from M and alloyed with Se and K grown from P and alloyed with Ge. It
was shown that within the given range of concentrations, Ge and Se affect the
process of supercooling only slightly. @.G,: Volkov. [Translation of abstract]

I ABSTRACT: In order to dotermine the general applicability of the regularities
characterizing the relationship between surface phenomena and crystallization pro-
c6ssos in indium antimonide mielts, the following phenomena were investigateds surface
tension of melts of the ga1lium-antimony system) influence of zinc and tellurium on-
the surface tension of.gsLUium antimonidep and influence of these admixtures on the
supercooling of Ga-Sb melts and on the growth of oryqtals from the melts. It is
suggested that the behavior of the impurities in the solvent malt can be predicted
from the difference of aturface tensions in the case of type AIIISb antimonides. In-
AIIIBV compounds which orystallize in a zino-blende-type latticep a correlation
exists between the mean sitomic maber of the compound and the surface tension at the

malting pointl the higher-the mean atomic mmber, thJ lower the surface tension of
the compound. Data on the effect of To on the supercooling of indium antimonide in-
dicate that surface-active admixtures increase the probability of formation of a
solid phase nucleus. At:& certain concentration of Tog the growth of lamellar den-
drites of gallium antimoride was hindered# causing distorted dendrites to growg then
was stopped altogether as; the To content increased f@rther. The introduction of zinc
in appreciable amounts did not interfere with the gro6th of lamellar dendrites of
gallium antimonide. The regularities found by studying the role of surface phenomena
in the crystallization of' indium antimonide malts wer,e found to apply to g-1141= ,
antimonide as wellp and are therefor* thought to cover at least all compounds of type
AIIIBV which crystallize in a zinc-blande-type latti;oe. The paper was presented by
