reviewed 12/1956
The element X of the semi-group a be potentially invertible in 01 if there
exists a super semi-group ~fyn OL such that X possesses an inverse element in
4 . The principal result of the paper consists in the following very simple
assertion: In order that the element X of the semi-group CL is potentially
invertible it is necessary and sufficient that for every A E(31 each of the
equations
XS - A. SIX - A
possesses not more than one solution with respect to the unknowns S --_GL and
S,eoL .
The obtained results are illustuated by aid 6f some infinite matrices.

TITLE: The Modification of the PropertieE of Synthetic Rubbers, Containing
Active Functional Groups, Using Resorcin-Formaldehydo, Resin in the
Latex Stage
PERIODICAL: Kauchuk i Rezina, 1960, No. 8, pp. 13 - 18
TEXT: The strengthening effect of resorein-formaldehyde resin in synthetic
rubbers was studied using the usual processing methods, such as coagulation, rol-
ling and mixing, etc. It has been previously shown that in filling b~atadiene-
-styrene rubbers in the latex stage using resorcin-formaldehyde resin-, the rubber
mixtures produced are satisfactorily processed and the vuleanizatues have suffilciffnr
ly high physico-mechanical properties (Ref. 4). The properties of the filled rub-
bers depend to a great extent on tne amount of resin. the molar ratio of reser-cin
and formaldehyde and on several colloidal-chemical factors. The rubbers InvW11-
gated were regulated carboxyl-containing (KC -30-1 (SKS-'~O-1) b-utadiene-styrenr-
rubbers with 1.2% metbacrylic acid, and 2-methyl-5-vinyl-oyridine CKM1311-15 (Sylirvp-

ABSTRACTS In order to br d n the sourceorrawmaterials for to rubber industryp an ex-
tract named "azaroplast' 3=rbaydzhan aromatic pj:asticizer),P obtained from the furfur-

plast was tested in comparlpon with other common.1y used sof?ners in standard mixes
based on NK natural rubber 'and butadione-styrend-5SKS-IOARKlr6ubber and in a tread mix
consisting of 70% SKS-3 and 30%__11K.The tests showei-azaroplast to surpass the
other softeners in plasticizing effect. The vulcanization rate of mixes containing
azaroplast was practically the same as that of mixes with the other softeners. Vulcan-
izates of standard mixes based on NK and SKS-30ARK and containing azaroplast had in-
creased strength characteristics. Replacement of mazut with azaroplast in tread mixes
Will permit a considerable increase in the extrusion rate and produce higher strength

TITLE: Separation of cerium from other rare-earth elements using the method
of oxidation with oxygen under pressure
PERIODICAL: Izvestiya vysshikh uchebnykh zavedenly, Tsvetnaya metallurgiya,
no. 1, 19052j 115 - 120
TEXT: The authors studied the possibility of accelerating oxidation of
Ce3+ in aqueous pulp of rare earth element hydroxides by pressure as developed
in Oranienbaum (Germany). The acceleration can be achievad by the use of oxygen,
and by raising the temperature and pressure. Experimental investigations were
made on a I-liter-autoclave with a Vishnevskiy electromagnetic mixer at 2,600
rpm. The solid-liquid ratio in the pulp was 1 : 5. The necessary alkalinity
of the pulp was obtained by the addition of a 40% NaOH solution. To produce a
neutral or weakly acid medium the pulp was neutralized with nitric acid. The pff
value was determined with a JM-5 (LP-5) potentiometer with a glass electrode.
The effect of the oxidation medium, the temperature ~-md the method of preparing
the hydroxide, on cerium oxidation in the pulp was investigated. Studying

the effect of alkalinity, partial oxygen pressure and temperature on the rate
and completeness of cerium oxidation, the following optimum conditions were
found: pH = 10, oxygen pressure 5 - 10 atm; temperature 1300C. Under these
conditionz full Ce oxidation is obtained within 30 minutes. The rate of Ce3+
oxidation depends on the method of preparing the hydroxides; oxidation in a
mixture of hydroxides precipitated from chloride solutions with ammonla, pro-
ceeds incompletely. In a mixture of hydroxides, obtained by the decomposition
of bisulfates, or precipitated with caustic soda, cerium oxidation proceeds r-a-
pidly, Cerium concentrates with up to 95% Ce02 content can be obtained, This
article was recommended by the Kafedra metallurgii redkikh metallov (Department
of Metallurgy of Rare Metals) at the Krasnoyarksiy institut tsvetnykh metallov

TLXT: The authors investigated the possibility of

temper~atures k25-200 OC) and partial pressu'res (3-15 atm), using
in the 6xperiments a mixture of alkali earth hydroxides obtained
from a melt of chlorides containing, 29.55 rare earth ciements
(of which 50.9 waz CeO,)) 7-01 CaO; 2.37 SrO; 0. 5 1 NnO;
0.23 Fc2U3; 0.43 ThO2. After solution of the chlorides in a
2';o hydrochloric acid and purification from thorium and partially
from iron and manganese, the rare earth elements were precipitated
as acid sulphates and the latter decomposed with sodium hydroxide
(in some cases directly precipitated with sodium hydroxide or with

ammonia). oxidation was carried out in an autoclave fitted with an
electromiagnetic stirrer. The solid to liquid ratio in the pulp was
1:5. Results: it is possible to accelerate the oxidation of
hydroxides of rare earth elements in an aqueous pulp with oxygen
under pressure. ()ptimum conditions- pH = 10, oxygen pressure
10 atm, temperature 130 OC. Under these conditions complete
oxidation of cerium is achieved in 3() minutes. The velocity of
oxidation of Ce--*)+ depends on the method of preparation of the
hydroxides. oxidation in the mixture of hydroxides, precipitated
.L
from a solution of chlorides with azatzionia, is incomplete; Ce
oxidises rapidly in a mixture of hydroxides produced by decom-
position of acid sulphates, or precipitated with sodiurn hydro-."'ide.
After the oxidation, cerium was separated from other rare earth
elements by treatineat with a 101"i) nitric acid. Concentrates
containing up to 95c/o of CeO,, can be obtained.

TEXT: Generation of high-power bursts of ultrashort-wave
frequencies is of importance in linear accelerators of heavy
particles. A pulsed oscillator based on the triode, type
rvj-L,.A (GI-4A), was therefore developed. Constructionally, tho
oscillator is based on coaxial tuned circuits, in which the
tube operates as a grounded-grid system (Ref. 1 - M.S. Neyman
Triode and tetrode generators for UHF (Triodnyye i tetrodnyye
Seneratory SVCh), Sovetskoye radio, 1950). The anode-grid
resonant circuit is in the form of a quarter-wave line,
terminated with the interelectrode capacitance Cag (Fig. 1).
Since the external diameter D = 33 cm, internal diameter
d = 14 cm and Cag = 35 PF, the resonance frequency is 142 Mc/s
and the length h of the anode grid-tuned circuit is 19 cm;

these calculated data -were verified experimentlly. The
cathode-grid circuit is in the form of a short-circuited
polycylindrical coaxial soction of a half-wave line; this is
terminated with the capacitance Cag . The feedback is providod
by three non-adjustable loops positioned at angles of 120 0
-vith resnect to each other, in such a manner that the loops pass
through the common wall of the resonators. Tae separator
condenser in the anod-grid circuit consists of six 'groups of
condensers, each consisting of ti-,o condensers in series. Tlie
oscillator was tested wita an 82--_1 resistive load, i-.hich was
in the form of a polystyrol cylinder with a water solution of
sadiwn carbonate. It was possible to obtain a maximum power
of 1.2 MW with an anode voltage of 32 kV and pulse duration of
450 -its. The oscillator was also tested with a high I-Q load
formed by the resonator of a linear proton accelerator; this
had a resonance frequency of 142 Mc/s and a quality factor of
50 000. It was found that at an anode voltage of 36 kV the
resonator of the accelerator received a power of the order of
500 WV, so that the protons could be accelerated up to energies

TITLEi Passage of intense pulsed electron beams through dielectric
tubes
PERIODICALs Zhurnal tekhnicheskoy fiziki, v. 31, no. 6, 1961, 751 - 753
TEXT: The passage of an electron beam through metal tubes had been studied
in theoretical and experimental papers by E. G. Linder and K. J. Herng-vist
(Ref. 1: Journ. of Appl. Phy3.~ 21, 10889 1950)9 by H. F. Ivey (Ref. 2t
Advances in Electronics and Electron Physics, 6, 137, 1954), and by M. D.
Gabovich (Ref. 3: UFI;, 56, 215, 1955). On the passage of a beam through
a tube, the residual gas is ionized, and positive ions as well as slow
(secondary) electrons appear in the tube. In the'case of a metal tube,
these secondary electrons reach the wall, and do not participate in the
further processes related to the passage of the electron beam through the
tube. If the dielectric tube is "oVerneutralized", the secondary electrons
will first reach the wall, and, after a certain time (of the order of magni-

hag an effect upon conditions on the passage of the beam through the tube,
particularly upon the energy of secondary electrons. An experimental study
has now been made of the passage of a pulsed electron beam through a dielec-
tric tube. The experiment has been conducted in the following manner: A
square voltage pulse having an amplitude up to 50 kv, a dura 4.4,usec
(Fig. Is), and a frequency of 50 pulses/second was applied to"Otneoelectron
gun placed in a vacuum chamber at a pressure of 2110-6 mm Pg. The gun per-
mitted obtaining an electron beam with afi amperage of up to I a in the
pulse. The electron beam was injected into a quartz tube with an internal
diameter of 9 mm and a length of 120 mm. On the other side of the tube, the
vacuum chamber was connected-with a device, by which the pressure in the
chamber was varied from 2-10 4 to 10- mm Hg. Part of the beam reached the
electrostatic analyzer, by which the energy spectrum of the electrons in the
beam was determined. A 30-mm wide metal ring, used for measuring the radial

to diffusion and other factors, will start moving to-ard the wal), rhi3e the

passing through the quartz tube, measured with the electrostatic analyrer,
permits distinguishing two separate electron groups, i.e., a grcup of f,,st
electrons and a group of slow electrons. lf, under the same cunditionf- the
electron beam is allowed to pass through a metal tube. the spectrum wili, as
usual. consist of fast electro'ns only. Experiments have been conducted to
determine the moment at which slow electrons of a given energy appear in the
beam.. The time wan ralculated from the beginning of the voltt.13'~ pulse at
the electron gun onward. The moment at which slow electrons appear at the
analyzer output as a function of their energy is presented in Fig. le. As
may be seen from Figs. 1b and 1c, Blow electrons do not appear in the energy

under which oscillations are excited, the frequency spectrum, the
amplification coefficients, the character of instability, and com-
parison of the experimental data with the theory. The electron beam
had an approximate energy 15 keV and a current 5--8.5 A. It was
injected in a quartz and glass plasma chamber, ionizing the air in
it, producing a plasma, and interacting with the latter. After
passing through the plasma the beam was electrostatically analyzed.
The procedures used to measure the various parameters are described.
The experiments have shown that the beam loses an appreciable part
of its initial energy (-18%). This energy is consumed in excitation
of oscillations and heating the plasma.' Some 50--60% of the energy
loss goes to excitation of longitudinal space-charge density waves
and transverse electromagnetic oscillations; this agrees qualitative-
ly with the theory. It follows from the measurements that the am-
plification coefficients and the maximum resonant frequency are also
in satisfactory agreement with the calculated data. The longitudinal
space charge density waves excited in the plasma and in the beam have

71' TITLE: Spectroscopic investigation of the interaction of plasma with charRed
particle beams

ABSTRACT: A spectroscopic study was made of processes taking place in the inter-
-aciion of beams with plasma in order to establish quantitatively the main parameters
of the process and their interdependencies. Electron temperature, ion temperature,
and high-frequency field strength were determined experimentally. In the electron-
temperature measurements, a 12-amp, 20-kev electron beam was passed through a dis-
8 X 10-4 to 10-2
charge tube at pressures from mm Hg. Pulse duration was 4.5 Usec,
frequency 50 pulses per sec and beam diameter 20 mm. Plasma density with passage
of the beam reached 6 x 1011 per cm3. The process took place in a constant magnetic
field of 0.12 emu. The discharge tube was filled successively with argon, helium,
hydrogen, and air. High-frequency oscillations generated by passing an electron beam
through a plasma were measured within the 600-2000 and 2400-7500 Mc ranges.

Oscillations within these ranges occurred at pressures of;5 x 10-3 and lower, the
averaged electron temperatures being 88, 65, and 66 ev at 5 x 10-3"4 x 10-3, and
3 x 10-3 mm Hg, respectively. The electron temperatures at higher pressures
(1 x 10-2 mm Hg), where no oscillations-occurred, were 2 to 3.5 times lower.
Measurements of the radiation intensity were conducted to determine the character
of its relation to the current pulse. The shape of the luminosity curve suggested
that it is a result of high-frequency plasma oscillations and, to a greater degree,
idthe colliRtcnless hea'ting'of plasma electrons. The ion-temperature measurements
were based on profiles of the spectral lines of ions and atoms. A.table summarizes
the results from ion-temperature measurements for oxygen, helium, hydrogen, and air
and hydrogen. At higher pressures, high-frequency oscillations did not occur, while
ion temperatures were about half the values given in the table. The temperature rise
apparently is caused by both collisions and the effect of a constant electric field.
A profile widening observed in the case of hydrogen atoms is attributed to the high-
frequency Stark effect. The authors thank Ya. B. Faynberg for a continued interest

ABSTRACT: Converters for changing microsecond time intervals into digital code are
designed for measuring the periods of time (time of flight) between some "zero!'
moment determined by a start signal and the moment of particle registration by a de-..
tector. Since these periods may be comparatively long (hundreds of Usec), beginning
of measurement should be shifted along the time axis to coincide with the arrival of
a "delayed" start signal. Delay is achieved by scaling of timer pulses. The start
signal triggers the "clock", i. e. opens the switch of the timer pulse generator so
that pulses are fed to the address unit. Channel width stability is maintained by
using quartz frequency stabilization. It is preferable to have both fast and slow
measurement conditions. Distributions are measured cyclically in either case. Under
conditibna of fast time analysis, the detector pulse blocks the input to whielf it is
fed and the tinier pulse output during the registration period after arrival of the de-

-..layed start signal. Upon completion of registration, the address is corrected (sup-
plemented) by the number of channel pulses transmitted during the blocking time, i. e.
during the dead time Tm. Under slow analysis conditions, the input switch is opened
with arrival of the delayed start signal, and the detector signals are sent to an
arithmetic unit. The next channel pulse closes the input switch after which counting
and recording take place. The signal for termination of recording sets the number of
the following channel in the address register and opens the converter Input after a
brief delay. Thus the information atored in the arithmetic unit before arrival of the
next channel pulse will belong to the channel whose number is determined by the pre-
ceding cycle. The accuracy in measurement of time intervals is determined, and the
ffect of asynchronous and delayed start signals is described as well as synchroniza-

ABSTRACT: The microsecond time interval to digital code converters are intended for
measuring time intervals (flight transit time) between a certain initial time "zero"
corresponding to a start signal and the time when a particle is registered by a
detector. Since these intervals may be long (hundreds of milliseconds) it is expedi-
ent to shift the measurement start time along the time axis so that it coincides
with the arrival of the "delayed" start signal. The time delay is implemented by the
pulse counting method. The start signal starts the "clock," i.e., opens the gate be-
tween the pulse generator and the counter. The pulse generator uses a quartz crystal
for frequency stabilization. It is.expedient to have two measurement modes: fast and
slow. In the fast time analysis mode the detector pulse after the arrival of the de-
layed start signal blocks the input at which it enters for the duration of registra-
tion. The timing pulse output is also blocked at this time. At the end of the

registration the address is updated (complemented) by the number of pulses which were
passed when the input was blocked. In the slow time analysis mode the input gate is
opened with the arrival of the delayed start signal at which time the detector signals
are applied to the arithmetic unit. Tne next pulse in line shuts the input gate. The
read and write operations are executed next. The "end of write" signal determines the
number of the succeeding channel in the address register and after a short delay opens
the converter input. Thus, the'informarion stored in the arithmetic unit, until the
arrival of the succeeding pulse, belongs to the channel whose number is determined by,
the previous cycle. The accuracy of the time interval measurements is determined.
The effect of asynchronism between the-starting and the delayed starting signals is
described along with the effect of frequency divider jitter, detector synchronization,
and blocking. The description and the characteristics of the converter, phasing pulse
generator, and channel pulse shaper circuits are given. (Translation of abstract] i
