TITLE: Magnetic.logic elements and devices in contactless control systems
SOURCE:. Elektrotekhnika, no. 9, 1966, 35-37

ABSTRACT: The Kalininskiy Electirc Apparatus Factory has begun producing the new
ELM-400 series.of magnetic logic elements. T.he plug-in encapsulated modules
(55 x 22 x 32 mm) were designed to operate at 400 cps using two-phase power in an
environment with an ambient temperature range from -35 to +50 C and relative humidity
up to 98%. The line includes: 1) an inverter (ELM-400-IN) which may realize the
NOT or OR function6 depending on the connections used (its fan-out is 6); 2) a signed
repeater*(ELII-400-P) wbich shifts the signal by one half period but leaves*it
logically Intact (fan-out is-6); 3) an input transfo r coupling circuit (ELH-400-V7%
and 4) an input inverter coupling circuit (EL*-400-VIN). The ELM-400 line complements
the LT general industrial application series. A special 1-kw power inverter feede the
400-cps contactless logic elements from a 50-cps power source. The factory also
I

ACC N . AP6031523
produces 50-cps magnetic amplifiers capable of delivering up to 550 va. to actuating
mechanisms and 400-cps amplifiers with maxim output power of 90 w. Transistorized
power amplifiers (90 w maxi ) are also manufactured, as are thyristor circuits
which may control high-power systems such as 3-phase 10 ke/380 v induction motors.,

PERIODICAL: Byul. Komis. po opredeleniyu absolyutn. vozrasta geol.

ABSTRACT: Tests were made on the constancy of the ratio of activ-
ity between the uranium and the actinium series in a
large number of minerals. Data were also obtained on
the ability of some products of the actinium series to
migrate under natural conditions. In the test for Ac/Ra
in the primary minerals--various oxides, aluminum sili-
cates, titanates, zirconates, niobate-tantalates, phos-
phates, tungstates, and asphaltites--it was shown that
the ratio in these minerals Is norml. In secondary
Card 1/3 minerals, Ac/Ra may deviate markedly from the normal.

15-1957-10-14194
Investigation of the Actinium-Radium Ratio in Minerals '
This deviation is explained by the complex processes of migra-
tion of the radioactive elements. For the majority of secondary
minerals, it was observed that Ao/Ra 1. It is possible that
this value is, in many cases, due to the accumulation of the
radioactive elements of the parent rocks. In many secondary
minerals in the zone of oxidation, Ac/Ra is controlled by the
migration of Ac and Ra. In some cases Ac/.Ra 1. This relation-
ship may occur only if the decay products of U migrate. Spring
deposits show a very large fluctuation of Ac/Ra (0.03-17). In
some primary minerals Ac/Ra 1, although the age of the minerals
is known to be older than needed to establish equilibrium in the
uranium series and between uranium and actinium. Such minerals
are said to be anomalous. The majority of the anomalous miner-
als studied are only weakly active, their content of radioactive
elements being below the average for the earth's crust. An
anomalously high Ac/Ra occurs in many primary minerals, chiefly
of hydrothermal origin. The largest anomalies ratio is found in
minerals which, to the eye, are well preserved, and it Is also
found in many minerals that are stable in the zone of oxidation.

15-1957-10-14194
Investigation of the Actinium-Radium Ratio in Minerals
Secondary alteration of minerals in the zone of oxidation does
not produce an increase but more commonly a decrease in the
anomalous value. The anomaly coefficient, on the average, in-
creases in weakly active mineral varieties. The cause is anom-
alies in primary minerals is essentially different from the in-
crease in Ac/Ra that occurs in young secondary minerals. These
anomalies are explained both by the more rapid accumulation of
Ac than Ra in young uranium minerals and by the ability of Ra
to migrate. Anomalous minerals encountered in geochemical as-
sociations do not display enrichment in the radioactive ele-
ments. The authors have shown that it is possible to deter-
mine the age of young minerals by the ratio of Ac to Ra.

TITLE: The Determination of Boron Content by Means of Irradiation With

PERIODICAL: Uch. zap. Kazakhsk. un-ta 1957, Vol 30, PP 7 - 11
ABSTRACT: A method was described for determination of B based on its raised
ability (in comparison with other elements by a factor of some
hundred) to absorb slow neutrons with the emission of Ok -particle
and M7 nuclei according to the reaction; BIO + n - He4 + M7,
the quantity of which is practically proportional to the B content
in the analyzed sample. A layer (3 - 5 m9/cm2) of the finely-
ground material to be analyzed is irradiated by neutrons from a
Ra-Be-source ( r"' 0.15 Curie) moderated in a block of paraffin
7 cm thick, and the number of M -particles and M7 nuclei which
are emitted by the sample in a time unit, is measured by means of
Card 1/2 a counter installation with a pulse ionization chamber. The content

The Determination of Boron Content by Means of Irradiation With Slow Neutrons
of B is found from a calibration graph plotted with the application of
standards made of CaCO with additions of determined quantities of H BO
Jrg3
In the case of a prope; radioactivity of the analyzed samples exceed
0.5 pulses per min, an allowance Is made for the counting rate without
irradiation by neutrons. The mean error of B determination at a content of
;P 1% is t 10%; the determination lasts - 0.5 hour. In the case of a de-
crease of the B content to 0.1%, the mean error rises to 130% and the deter-
mination takes several hours.

TITLE: Change in the Isotopic Lead Composition During the Pre-
cipitation of Natural Minerals (Izmeneniye izotopnogo so-
stava svintsa pri vydelenii iz prirodnykh mineralov) *
PERIODICAL: Izvestiya Akademii Nauk SSSR, Seriya Geologicheskaya, 1958,
Nr 5, pp 40-49 (USSR)
ABSTRACT: The authors studied the possibility of changes in the re-
lation between the radioactive and the resistant lead iso-
topes during the transition of this element into liquid
solutions of natural minerals. Three resistant isotopes
of lead are the final product of the disintegration of the
radioactive series, and the correlation of the lead iso-
topes is important for determining the absolute age of geo-
logic formations. The lead method is the most reliable for
this purpose, although it often gives different results in
the calculation of the geologic age on the basis of the
correlation of different isotopes. Latest research has
been concerned with determining the age of secondary miner-
als which - during their formation - trapped the lead from
primary radio-active minerlaa. Based on the study of the
Card 1/3 isotopic composition of the lead, they do not take into

consideration the possibility of the variation of this com-
position during the isolation of the lead from the minerals.
The authors studied the variation of the relative content
of radioactive isotopes of the lead as follows: the pro-
duct of uranium desintegration - RaD and the product of the
thorium desintegration - ThB during their isolation from
natural minerals, that is the specific activity of RaD/Pb
and ThB/Pb, where Pb is the total lead of the mineral.
The authors describe in details their procedure and cal-
culations and come to the following conclusions: 1) the
ore lead is able to isolate from primary minerals in a
larger quantity than its radiogenous and radio-active iso-
topes; 2) RaD is extracted from the uraninite in a larger
degree than the radiogenous resistant lead isotopes; 3)
ThE is lixiviated more than RaD 4) due to the degree of
capacity of transition into a liquid phase from primary
minerals, the foll ing series cf isotopes is set: Ore
lead and ThB> RaD7 radiogenous Pb; 5) Pb is found in
lesser quantities in comparison with radioactive elements

TITLE: Investigation of the Neutron Flux of the Earth's Crust
(Issledovaniye neytronnogo potoka zemnoy kory)
PERIODICAL: Geokhimlya, 1959, Nr 21 PP 105-109 (USSR)
ABSTRACT: In 1957 measurements of the neutron flux were carried out in
the ore districts of the following Soviet Republics:
Kazakhakaya SSR Akchatau, Vostochnyy Kounrad and others),
Armyanskaya SSR Raftharan, Dasiakert, Kafan), Gruzinskaya SSR
(Kvaysa)t Kirgizkayja SSR (Ak-Kul-). In order to eliminate
the effect of secondary cosmic radiation, the measurements
were carried out in mines. Proportional counters of the
SNM-8 type with amplifier and recording device and filled
with BF were used in the measurements. Three types of measure-
3
ments were taken: 1) Slow neutrons and the background were
measured by means of a counting tube without filter; 2) A
counting tube with a paraffin filter as a moderator was used
to measure fast neutrons and the background; 3) For measure-
Card 1/2 ments of the background alone a cadmium filter was attached.

Investigation of the Neutron Flux of the Earth's Crust
Results are listed in tables I and 2: besides geological
formation, location, and genesis? the activit (i jor/h)
and flux of slow and fast neutrons (in n/cm27h) are given.
Gamma activity and the intensity of the neutron flux are
usually proportional. In the Aktyuz deposit the intensity
increases to 32.4 fast neutrons/cm2/h and 28.2 slow neutrons/
CM2/h. A dependence of the intensity on humidity was observed
in the Vostochnyy Kounrad mine. There are 2 tables and
7 references, 2 of which are Soviet.

ABSTRACT: The existance of the neutron flux in the Earth's crust is
determined indirectly by numerous reactions 3f artificial
transformations: 1) the accumulation of He in the
spodumenes for the count of splitting the lithium; 2) an
artificial division of AcU with the formation of isotopes
of krypton and xenon; 3) the accumulation of xenon in the
ancient tellurous minerals of 2~ 5gon ~31 neon in the urani-
~
nites; 4) the formation o
Pu , Np and other iso-
topes of the neptunian series in radioactive minerals. The
formation of products of nuclear transformation cannot be
explained uniquely by the presence in the minerals of radio-
active elements capable of spontaneous splitting with the

beryllium mineralization and in the non-active zones of

neutron flux was found. The flux was composed maknly of
flow neutrons from the atmosphere, as far as could be
judged from experiments with screening theiq&iates by a
cadmium.filter. The fast neutrons were beyond the measur-
ing limits. Also,.in..the laboratory and on the glacier,
no measurable flux of slow neutrons was found. Only in
the zone of beryllium mineralization with an increased
activity was a considerable increase of the neutron flux
found. Presumably it was a result of a combination of
two factors: 1) a sufficiently strong flux of alpha-
particles; 2) the presence of the matter capable of
Card 2/3 generating the neutrons. According to the authors, that

TEXT: To determine small quantities of thorium'(down to 10-4s)
in extracts of some minerals, use was made of a method based on
the recording of fragments from the fission of thorium nuclei
during irradiation by neutrons from a Ra-Be source. Thorium is
removed from solution by co-precipitation witl~ cerium oxalate and
~the precipitate is placed-in an ionization chamber. It is then
irradiated with a beam of fast neutrons and a number of fission
events is recorded. In the presence of U measurements are made
of the number of fission events produced by fast and partly
slowed-down neutrons.

of 20 - 25/a. It is estimated that one recordedoi-particle corres-
ponds to the passage of 160 neutrons through the emulsion. Data
are given about the neutron flow at the ground surface and in sub-
terranean workings, and considerations are expressed about.the naw
ture of this flow. The suggested method was employed In the study
of the radiation of "anomalous" minera-1s, containing an elevated
quantity of actinium. Molybdenum M-,Ir/(M-17), containing 6.8 x 10-.6
g/g U and possessing an Ac/Ra ratio 9.4 times higher than in the
usual equilibrium minerals, served as the main specimen of an ano-
malous mineral. It was established that anomalous minerals contain
a considerable excess of particles with runs of less than 8/1.
Tracks of short-run particles, differing from those OfO(-Particles
in their greater width (up to 1.5 - 2,,u) and grain density, were
detected as a result of investigating 2900 tracks of anomalous mi-
neral preparations. The mean run length of the new type of tracks,
which are practically identical to the tracks of division -fra-g-

8 In the present work the isotopic composition of uranium was inves-

magnetite, thorite, cinnabar and schroekingerite), as well as in water being in
contact with granite mountain regions. Separation of ur_anium isotopes, namely of
the U238 mother (UI) and the disintegration product U234 (UII) was already ob-'

In the UII/U1 ratio is observed in minerals exposed forr.long time to the effect
of natural water. The present experiments were carried out with an oL-analyzer
(designed by Ye.A. Isobayev) containing a six-electrode-electron impulse chamber
as impulse indicator. The uranium samples were placed on six disk-shaped high-
voltage electrodes, which were fixed on a cylinder. Rotating the latter the sam-
ples were brought into measuring position (without dismantling the camera), and
the spectrum of the samples was immediately compared with the standard. Two am-
plitude analyzers were used, one with 19, the other with 50 channelp. Uranium
was extracted with ethyl ether from HN03 solutions of the ore and was electrolyt-
ically deposited. The intensity of the spectral lines of -JII_gnd UI (see Pigure)
was determined from the area limited by the line, thus 2 , 10 g uranium could
be determined with 10% accuracy in 3 h. Actually the urarlum content was n . 10-4
g and the accuracy of UIIMI measurements was 1 - 3%. In some samples the rela-
tive u235 (AcU) content was determined, measuring the activity of fission frag-
ments effected by neutrons fromaPo-Be source. Revising previous determinations

TITLE: Investigation of actinium in natural objects
PERIODICAL: Radiokhimiya, v. 2, no. 1, 1960, 98 - 103
TEXT: Two different methods for determination of small amounts of actinium
in the presence of th9rium were developed and previous data-were checked concern-
ing minerals with excessive actinium content among primary minerals. The charac-
teristic of these "abnormal" minerals (being principally of the hydrothermal
phase) was that often some paragenetically connected minerals of the same layer
had an excessive actinium content. The c,---Igin of this actinium excess (possibly
accumulated as fission product) will be discussed in a following publication.
Since the excessive actinium content is observed in minerals with aow activity a
more sensitive measuring technique has to be applied. One of the two methods
presented is based on measurements of AoC-activity in an active deposited sample
by an OL-analyzer. The latter was assembled by Ye.A. Isabayev and contains an
argon-filled electron-impulse chamber and a 19-channel pulse-analyzer operating
in electron commutation circuit. On the same deposited sample ThX (ThC line) and

AcX (AcC line) could be determined with 50% accuracy for 5 - 1o-5 g actinium.
Radium could be determined from RaC'. The active deposit sample was prepared by
passing air through the-radium-oontaining solution for 2 h at 800 =3/min rate.
Radioactive emanation was thus transferred into,a Special activation chamber. Ptr
radium determination the solution saturated with emanation was transferred in an
evacuated chamber, where the active deposit was exposed for 2 h. The oylinder-
shaped electrode was in both oases quickly removed into the chamber of the M-ana-
lyzer and measurements were carried out 5 min after the aotivation. 11be second
method of actinium determination is based on pulse counting of total activity An
+ AcA. The emanation was transferred with air into the counting chamber. The
walls of the latter wore surfaces of phosphors of two luminescence counters. Us-
ing a device constructed by U.Kh. Asvlbavev and L.I. Shmon1n, pulses were record-
ed with 5 microseconds of retardation, corresponding to An + AcA decay. The
background is represented by; I - a(Ac + bTh)2 + aTh (a, b, c = parameters).
The first therm represents the number of false coincidence and the second the num-
ber of retarded pulses from Tn and ThA decay. Besides, the device counts pulses
of single Ot-particles, i.e., activity Ac + bTh. Passing air through it at a rate
of 100 cm~/min, mainly thoron is measured, counting v70 epm for 1 mg Th, while

amounts'. Both presented methods have nearly the same sensitivity. The second
method was used in the present investigations only for Ao and Th determination.
In the future the sensitivity of the device will be improved, and will be applied
to determinations of small radon quantities. Detailed descriptions of the device
will be given in a separate paper. In the present experiments 25 minerals were
investigated, 15 of which were molybdenite samples. The measured activities (Ta-
ble 1) demonstrate increased actinium content in 3 of the molybdenite samples.
Uranium content changed in molybdenites from 3.0 - 10-5% to 3.3 - 10-3%, while
the ratio Th/U varied from 0.5 to 3.6, having a mean value of Th/U - 1.5. Ac-
.cording to previous observations of the authors in minerals containing an actini-
um excess, considerable deviations in content of uranium or thorium isotopes from
radioactive equilibrium were not observed. One of the pitchblende samples showed
a sharp change in the ratio of isotopes, even in single.mineral grains of the
same 200 g lump. In two grains an increase in the ratio Ac/Ra to 9.4 t 0.4 was
observed, effected positively by migration withdrawal of uranium (Table 3). The
polonium content is also considerable. This pitclfDlende sample is considered by

PERIODICAL: Priroda, no. 6, 1962, 42-44
TEXT: The development, special features and practical significance of the
method of determining the absolute-age of rocks According to the accumulation
of argon in potassium minerals,are discussed. Academician V.G.Khlopin and
Doctor of Chemical Sciences E.K.Gerling first showed that this method could
be applied in practice. In the period 1948-61, it was developed at the
Leningradskaya laboratoriya geologii dokembriya Akademii nauk SSSR (Lenin~;_rad
Laboratory of Pre-Canbrian Geolo67 of the Academy of Sciences USSR), where
it was also used by Academician A.A*Polkanov for interpreting the history of
V
Pre-Cambrian sedimQnfs in the Baltic Shield. For the discovery and develop-
ment of this method, Polkanov and.Gerling were awarded Lenin Prizon in 1962.

They showed that there is an increased A40 content in potassium minerals,
that nonradiogenic argon impurities can be easily excluded, and that there
is an increase in the A40/00 ratio in old minerals, the age of which is
known according to other data; hence they determined with sufficient ac-
curacy the constant of argon formation. Much research conducted by Gerling
and others was connected with.the preservation of argon in miherals. Exten-
sive experiments on argon release during the heating of minerals emphasized
that biotites retain argon well. For the first time,it has been possible to
establish the age of stony meteorites according to the argon conten.t and to
divide these meteorites into genetio 8roups. The first investigations in
this'connection ae .re conducted by Gerling and T.G.Pavlova in 1951- Chondrites
indicate an age of UP to 4.8 billionyaars, while meteorites bearing traces
of remelting appear to ~e much younger, probably because of argon losses.
In achondrites, the helium and argon content in exceptionally high; they are
probably the remnants of the primary atmosphere of a cosmic*body. The argon
method is most yaluable from the point of view of dating rocks: particularly
for substantiatin& the chronology of the Pre-Cambrian period. The combined

1200-500 million years upto the pre~ent,a sort of lull in the Earth's

were weakly revealed, and that the rate of deposition of sedimentary rocks
was ettremely small. In the USA, more than 20 laboratories, many of which
are attached to industrial organizationsp are using the argon method.

ABSTRAM.-The polarization of cosmili..ray muons was investigated at 3860 m above sea
level at Pamir. Nuons Incident at zenith angles less than 200 were filtered through
116 g/CM2 of lead (linitlag,nuon energy 0.25 BeV) or 1100 g/cm2 of earth and lead
(limiting nuon energy 2.5 BeV),and decay positrons from muons brought to rest in a 45
g/cK2 lead absorber were counted separately in the upper and lower hemispheres. Posi- -
trons were counted for 4 Usect starting 1.7 Usec after the presence of a stopped muon

the lower and higher energy nuons were found to be 0.30 � 0.08 and 0.47 � 0.14, re-
iipectively. The polarization found for the lower energy nuons is in satisfactory
agreement with those found by other investigators at sea level. but the polarization
found for the higher energy nuous exceeds the values found at sea level by other In-
vestigators for muons of slailar energies by somewhat sore than the experimental error
It is suggested that this discropawy may be due to the. presence of a larger fraction
of nuons of X-mesonic origia at the higher altitude. Orig. art. has: 2 formulas 2
