ABSTRACT: After a short survey of publications (Refs 1,4,7) the
author stLLtes that his measurements conducted through
several years proved that the kinetics mentioned in the
title can be used as an indicator-of the state of the
tubers during the rest period. The data on the said kinetics
agree well with the results obtained by observations made
through mandr years by potato growers~ The results of
measurements showed that the rules governing the total
variation of electric conductivity in the course of the rest
period during an arbitrary kind of stozage may be represented
6Y a curve of equal shape. The curve of the aort Lorkh has

The position of these points (A,C,S)cbixends on the sort of
the tubers as well as of the conditions of storing and
growin.-. The position of the caid points corresponds
furthermore to the change of the water content in the
protoplasm, to its capacity of swelling and to the starch
content (Ref 2). If the rest period is divided into 3
phzLse3, the salient points separate the curve into
corresponding sections. The distance A E corresponds to
the total rest period, the distance B D to the duration
of the true reat (second phase). There are 1 figure and

ABSTRACTt The optical conditions for the photometric determination
of thorium were devised on the basis of standard curves
by means of the colorimetric photometer FEK-M using thoron
as reagent. As can be seen from the figure the influence
exercised by Ce and La upon the light absorption is suppressed
at pH 0.96 - 0.85. Small calcium amounts do not disturb. The
separation of thorium from Eodium, potassium, calcium, and
barium.is carried out by precipitation of thorium together
with Fe(OH) 3* The quantitative precipitation was checked with
UX1 and RdTh. The separation of thorium from iron and uranium
was carried out in weakly acid solution by precipitation with

TITLE: The Concentration of Uranium in the Waters of the
Black Sea
PERIODICAL: Doklady Akademii nauk SSSR9 19609 Vol. 132, No. 6,
PP- 1411 -1412
TEXT: It follows from an introductory survey publication that a fairly
equal distribution is to be found in the oceanag an average of
2-7-10-6'g/l. Strong deviations from this concentration can occur in
coastal waters and inland seas. The Black Sea has a special position
among those that are related to the ocean. The exchange of water with
the ocean is limitedg mineralization is diminishedp and the water is
contaminated with H S up to the upper 125-175 m- It is to be assumed
that under these CoRditions, hexavalent uranium is reduced to a state
of pentavalency. This should lead to active uranium sedimentation and

a change in concentration in the depths. Table 1 correlates data from
195 1and 1958 (central and western parts of the Sea).Uranium was de-
termined by a luminescence method from 0.3 - 1 1 samples with an ac-
curacy of + 20%. The authore draw the following conclusions from
Table 1: 17.the 6uranium conegntration fluctuates in the samples examined
between 105 10 and 2.8-10 g/1. 2) Theso variations occur on the
surface as well as in the depths. No regularity in these concentration
changes could be detected. Thus the specific reductive milieu of the
Black Sea from 125-175 m upwards remains without influence on the dis-
tribution of the uranium concentration. According to approximate cal-
culations, the average concentration of uranium in the part of the
Black Sea examined is 2.0 + 0-3)-10-6 g/1, which approaches the average
value in the ocean. The decline in concentration in the Black Sea does
not exceed 30-35%, while the mineralization is lowered by 54% in com-
parison to the ocean. The authors thank I. Ye. Starikq Corresponding

TITLEt The form in which atoms of radioactive elements exist
in minerals
PERIODICALs Radiokhimiya, 1961, Vol.3, No.2, pp.207-214
TEM The authors' study of the leachability of radioactive
elements from minerals has shown that their capillaries contain
atoms of isotopes of radium and other daughter radio-elements
finding.their way there through radioactive recoil. Uranium and
thorium, as well as various non-radioactive elements, are also
Present. They are leached out of monazite and viikite by the
action of acid solution even when they do not dissolve. These
results could be explained only by- the capillaries of these minerals
containing, in addition to daughter-element atoms, those of uranium,
thorium and the rare-earth elements. For a deeper understanding of
the form in which atoms of the elements exist in minerals, the
isotope ratios in the damaged parts of the mineral must be found.
The authors have developed various methods for finding that
proportion of atoms of elements which in located in capillaries and
damaged parts of minerals accessible to the leaching solution.

The form in which atoms EIII/E452
They have called the percentage of all the atoms of an isotope
present in a mineral which exist in capillaries and disturbances
of its crystal lattice the "limiting leachability" of this isotope.
Limiting leachability values show that capillaries contain enough
atoms to form an independent solid phase. The composition of the
compounds present there varies with the mineral. Different
minerals also have different capillary structures, which accounts
for the relative effects of neutral and acid leaching solutions
varying from mineral to mineral. Fig.2 shows the values of
limiting leachability for radium, uranium and thorium (curves 1,
2 and-3 respectively) as a function of acidity (0 -0.2 N hydrochloric
acid). This indicates that for determinations of limiting
leachability acid solutions must be sufficiently acid to dissolve
fully the colloidal compounds in the capillaries and bring the atoms
of the elements present there into a form capable of exchange with
ions of the leaching solution. Solutions containing salts. give
leachability values less than obtained with salt-free solutions of
the same acidity. There is no sharp boundary between the
capillary material, i.e. the fully disrupted lattice, and the
undamaged lattice. The maximum depth from whIch atoms can reach

the surface of the mineral crystal lattice will be different for
those formed in alpha-composltlon and'for those ejected from
lattice points by alpha-partic-les or recoil nuclql. The authoz;s
show, using results published by Ye.P.Patryayev (Ref-13:
Radiokhimiya, 1, 1, 105 (1959)) that in the test sample of monazite
'the' radius of the sphere without capillaries or damaged parts in
its surface is 1.7 x 10-4-cm, The surface zone has the greatest
damage and supplies most atoms entering the capillaries. Unlike
,atoms in capillaries, those in the damagbd'parts of the lattice
can only be removed by more concentrated acid solutions. The
dynamic,leaching of minerals by strong solutions of acids is a
fruitful way of studying this part of the lattice. For this
leaching rate relative to the quantity of s~,olution passing through*
a mineral-filled column in a given time interval is observed.
Graphical analyaia then enables the quantities of radioelemeht
entering the solution through leaching and through dissolution to-be
found separately. For most minerals, the authors conclude that theg,,'
main mass of Atoms composing th6 mineral are in the undamaged
lattice, a I art are in the capillaries and damage'd parts and

TITLE: On the Problem of Kinetics of Leaching Out
Radioactive Elements From Minerals
PERIODICAL: Radiokhimiya, 1961, Vol.3, No-3, pp.359-364
TEXT: Kinetics of the leaching process of radioactive elements
other than radium and its isotopes were not investigated. In
order to find out if the regularities observed for radium would be
applicable to other elements the author investigated the leaching
process of monazite and viikite from pegmatites of the Northern
Karelia. To weighed samples of the minerals crushed below
0,25 mm placed in beakers, a given volume of a leaching solution
was added. The leaching process was continued for a given time
on constant stirring. Then the solution was separated from the
residue by centrifuging and its content of radioactive elements
determined. The experimental results for leaching out with
hydrochloric and sulphuric acid solutions of ThX, U, Th, RdTh,
UXI and rare earth elements have shown that the velocity of
leaching out of all the elements studied is highest during the

first one to three hours of the process; due to desorption from
capillary walls, the main proportion of atoms of elements capable
of leaching under these conditions is transferred into solution
during that time. At long leaching times, the velocity of
leaching out sharply decreases and the transfer of atoms of
elements into solution is due to the solution of crystal lattice of
minerals as well as to diffusion of atoms of elements along
capillaries from the deeper layers of minerals. The observed
differences in kinetics of leaching out of various elements are
explained by differences in the form in which atoms are present in
capillaries of minerals, differences in the adsorption ability of
the surface of minerals in respect of various elements and the
composition of the leaching solutions used. There are 3 figures,
4 tables and 13 Soviet-bloc references.

TITLE. Concentration of thorium isotopes in sea waters
PERIODICAL: Radiokhimiya, v.3, no.5, 1961, 623-635
TEXT: A method of concentrating thorium isotopes from
large volumes of natural waters (200-500 litres) by their
--oprecipitation with iron hydroxide on cold and the determination
of thorium and ionium in the concentrates obtained was developed,
The experimental procedure is described in detail. Using this
method the concentration of thorium isotopes in waters of various
parts of the Black and Azov Seas was determined. The
concentration of thorium and ionium in the water of the open
part of the Black Sea was found to be (2.2 t 0.2) x 10-9 g/litre
and (2-5 1 1.o) x 1o-13 g/litre respectively. It was shown that
the concentration of thorium isotopes in water decreases from
coastal parts to the open sea which is explained by decreasing
concentrations of suspended matter in the water. That the
concentration of thorium decreases more sharply than that of
ionium or radiothorium is explained by the fact that thorium-232

is mainly confined to the coarser terrigeneous part of the

tolloidal part which settles to the bottom much more slowly and
is carried out into the open sea. The work was carried out in

TITLE: Study of the kinetics of formation of adsorption

indicators
PERIODICAL: Radiokhimiya, v.4, no-3, 1962, 322-328
TEXT: The authors present data obtained by studying the
formation of adsorption equilibrium during leaching of thorium
isotopes from monazite, with th 'e aid of radioactive indicator- UX11
The leaching was carried out by mixing the crushed mineral with
acidic solutions for various lengths of time. The time for the
formation of equilibrium between the surface of-the mineral and
the solutions, depended on their composition and primarily their.
acidity. This is connected with the fact that the initial stage
of leaching of polyvalent elements (Th, U, rare earth elements, etc)
from minerals is the solution of the hydrolysis products -forming
from the elements present in the capillary pores. The more acid
the leaching solutions the more rapidly the hydrolysis products
dissolve, thus letting free the ions of the elements, which then

distribute themselves between the surface of the minerals and.the
solution, alongside the'indicator ions. For sufficiently acid
solutions ( > IN ) the kinetics of the first stage of leaching
are determined by the rapidity of formation of the adsorption
equilibrium between the solution and ittincral. ' The time for this
process is not longer than 60 min. Much more time is needed for
weakly acid solutions. The'results for the leaching of monazite
with 0.07 N H2S04, 0.23 and 11.1 N HCI show that the
equilibrium times are 8, 3 and lh respectively. There are
5 figures and 4 tables.

TM: Ingots from rimmed steel; 7 tons in weight, poured from the top were
subjected to vibration on a vibrator with eccentric weights, whose rotation caused
a vibration of the bridge of the founding platform it a frequency of 1,470 vibra-
tions per minute and amplitude - I mm. Under vibration the intensity of the
steel ebullition In the mold was increased notably, the rising-was reduced and
the thickness of sound crust was increased. Depending on the duration of the
vibration it is possible to obtain any given thickness of dense crust, since in
order to obtain Ingots with 25-30 mm occurrence depth of cellular bubbles it is
sufficient to subject them to vibration for 5-6 min from the moment the pouring
starts. Under 7 minute vibration the cellular bubbles were situated at a distance
of 42 mm from the surface and under vibration for 24 min 2D see they vanished.

sections,were photographed, cand samples were cut from the 3. 5, 8, 1Z, 13, 15,
17, 20, and Z57o horizons, as measured from the top of the ingot. Templets were
cut for metallographyj the templets were deep-etched, sulphur- printed, and
chemically~ at*nalyzed. A detailed description is given of the casting process, and
the composition of the test melts is tabulated. The results of the casting of 7-ton
ingots at various iimerates, with and without vibration, are also tabulated. The
character 'of the rimming of ingots subjected to vibration is shown to be greatly
alteiedf and shortly after commencement of the Vibration the rimming becomes
violent, to the point of gushing and spr'aying. Instead of the ordinary peripheral
rimming of steel OT . 3 (St. 3) along the interface of the liquid and solid phase a the
vibrated steel, rims all over. Contrary to the continuous growth of brdinary Ingots,
which beginfj~ 1-2 min after the pouring Is stopped, vibrated ingots sag 30-50 mm,
and e%en up-to 100 nim, within 7-8 min and then grow slightly, but never back to
their initial level, unless the vibration is stopped prematurely. As to structure,
,vibration eliminates the ordinarily observed difference between the tipper and the
lower part of the ingot; however, some tendency toward the formation of cracks
in the lower, part of the ingot. is observed. 'In the ordinary ingots at the plant, the
dense external skin is 8-15 mm thick (thicker with slower pouring and with lower
Mn content)., The length of the honeycomb blowholes is about 80-100 mm; the

shrinkage porosity into the depth of the ingot. Vibration affects the distribution of
sulfides only,very little. Vibrated ingots have.sulfide veins that are the remnants
of the now-filled blowholes Spot-eample analysis atvarious depths shows that the

the vibratiOn., ids So and P contents in the outer zone are not aopre6tably affected
by vibration. thexone of concentrated liquation and the zone of porosity are
located more deeply in vibrated ingots,, as shown by chemical analysis. In summary,
vibration affords prod'ilction and faster ~ pouring of a rimmed steel with a higher. C

simplest cases measurement of the angular correlations yields the
spin and parity of the unstable particle. The calculations are
based on the theory of Migdal (ZhETF, v. 28, 3, 1955) and Watson
(Phys. Rev. v. 88, 1163, 1952), with the behavior of the cross sec-
tion of the three-particle reaction extrapolated to include the en--

(USSR).
ABSTRACT: After a brief survey of the methods of extraction e)f urani,L~i., whf~re-
by especially amines are effective for urany~-nitrate (references 1
to 3), the authors presume that not only compounds RMH IU02(1103)3)
are capable of being extracted, but also analogous compounds In
which the place of the nitrate-ions is occupied by any other anions.
In this case the hexavalent uranium can be extracted by means of
amines from solutions in which it forms ar-ion-complexc-is. This assump,
tion was e;xamined by the authors with acetate-solutiorzq in which., as
is Imown, the complex- CUO 2'(Ch3Coo) 3) -is forripd. (refr-,rence ],,). Aniline
was used both as complex-forming amine and a imultang. oils 1y as organic!

tic acid (figure 2). The knowledge on the extraction of uranium with
aniline furnishes no specifir data on the form ef the extracted ccm=

queous. solution in which 1 mol aniline corresponds to 1 mol urarium.
The modifications of the spectra of acqueous solutiong were investi-
gated with a constant concentration of uranium (0,03 mol) - when va-
rious quantltie~ of aniline were dissolved therein (figure. 1) - for
the purpose of determination of the composition of thJs complex corn-
pound. After various computations the authors foun-,J the fcrriula
C6H5NH3CUO2(CH3COO)3). The data 9n the formation of anilime-uranyl-
triacetate were confirmed in a preparatory way. The average results
of analysis vhich agree satisfactorily with those for the aforesaid
compound are given in table 2. The concerned compound is soluble both
in anilineY as well as in several organic solvents (alcohols, ketones).
It is insoluble in ether, chlorinated hydrocarbons and benzene.. The

TITLE: Present state and prospective development of optical devices
simulating the movement of fast moving objects
SOURCE: Moscow. Vyosheye tekhnicheskoye uchilishche, [Trudy] no. 103,
1961.Opticheakoye priborostroyeniye, 5-16.
TEXT: The author describes two optical methods of simulating the movements
of fast-moving objects in aircraft simulators, developed at the Department of
Optical Instruments at the MVTU im. Bauman, where research into the problem
of simulating fast-moving objects has been carried out for the last decade.
Results of this research are contained in the present article and in the
articles of-Ye.N.Lebedev, I.I.Pakhomov and 'V.A.Perov. The first method is
based on two principles: (a) simulation of the linear movement of a spatial
fast-moving target along the sighting line by means of a zoom collimator
around whose focus the spatial model of the aircraft revolves in sDace; (b)
simulation of the relative angular movements of the target by turning the

reflector of an optical target-sighting device in all three dimensions. Use
of this method in an optical collimation sighting system widely used in air-
craft firing sights,is described (Pig.1). Although this method is universal
and can be used in all cases when it is desired to reproduce the movement of
any spatial object alon.- a spatial curve in a relative coordinate oysten, thr:
targe! remains immobile in absolute anL-ular coordinates, It is therefore
suitable only for test benches and special-purpose trainers, not for uni-
versal trainers uliere it is necessary to simulate the movement of objcctr,
beyond the field of vision of the aiming -ight. A test unit for dyn,:-,ic -re-
search was constructed on the basis of this method. After further recea-.-c"),
the Department developed a second method, for both special-purpo2e und uil-I
versal trainers, in which the range is simulated by an oDtical system in
which both the objective and the obJect plane are moved by means of potel-.1---
ometric servosystems. The objective has fixed components, as in exi-,tin~-
Soviet optical systems with movable components aberration occurs when the
components are moved, and magnifications of only 4-5 x are possible. The
optical system devised at the MVTU has a magnification of 10 x and a total
maximum length of 290 mm, and uses a serial objective. Operation of the

where f'is the focal length of the objective, S' is the distance from the
objective to the image, S, is the distance from 1the model to the objective,
Sm is the distance from the model to the image, k is a constant coefficient
and U (t) is the change in the voltage in time. Plotting of the function
S'(t) is done by a nonlinear potentiometer. Plotting movements of the model
by a nonlinear potentiometer in an absolute coordinate system in the form
Sm (t) would have caused considerable design difficulties, as the latter
function is ambiguous on the working section upon variation of the magnifi-
cation above 5-6 x. The movements of the model were therefore plotted in a

When installing the system in the cockpit of a fiGhter-trainer, the swivel
reflector should be mounted higher than the cabin above the pilot's eye-level,

TEXT: A simplified analysis of the flow rests on the
assumptions of an ideal gas, a uniform distribution of the flow
parameters in the outlet section of the volute, and the flow
parameters at the outlet section of the entry so-cket being constant
in each cross-section of the volute. Analysis of the continuity ,
equation shows the ratio of the inlet-and outlet velocities in the
volute to be the main parameter which determines the volute
geometry. This ratio (the "acceleration factor") also determines
whether a bladeless assembly is advisable and :when it drops below
0.5, a bladed one is preferable. As the acceleration factor
increases, the radius of the volute decreases. Various relations

are derived and illustrated in graphs between the volute dimensions
and the acceleration factor. The model of a b1ndeless stator for
a rotor diameter of 130 lain, a rotor width of 12 mni and a flow
angle of 12* at the rotor entry was tested in the laboratory.
Energy losses in 1G cross-sections around the periphery were
ineasured together with the flow angles and static pre.-isures. The
static pressures ifere also measured in the entry sockeit and along
the mean volute line. Conclusions: the desi~--n procedute put
forward permits the determination of the volute geometry and the
behaviour of the volute flow under non-design conditions. The flow
exit angle from the bladeless assembly depends on the flow
velocity even at sub-critical heat transfer conditions. The
efficiencies of bladeless and bladed assemblies (with well
developed entry sockets*) are equal. The volute*must be accurately
macl~ined to avoid distortion of the velocity field at the turbine
inlet. The limits of application of the bladeless stator have not
yet been fully explored. There are 9 figures.
