TITLE: On the Methods of Determining Acid-, Ester- and Iodine Numbers in
Ligaite-Like Bitumen Substances (0 metodakh opredelerdya
kislotnogo efirnogo i iodnogo chisel v burougol'nykh bitumnykh
veshohestvakh)
PERIODICAL: ZavodskV& Laboratorlya, 1958, Vol 24, Nr 6, pp 692-694 (USSR)
ABSTRACT: Two different methods of determining the content of unsaturated
compounds in fats, oils, and mineral oil products are described
in publications, v1z.,, the methods developed by Gyub2 and
M&rgoahes respeatively. Whenever the latter method was applied
to bituminous substances, the results obtained were mostly not as
good as those obtained by the other method, which is explained by
the incomplete dissolution of the unsaturated ligaite-like bitum-
inous substances in alcohol. The difference between the results
obtained by the two methods is shown in a table. The method of
determining the aoid number described by G.L.Stadnikov (Ref 1) is
analogous to that mentioned in OST-7872-36 and GOST 5985-51 for
mineral oils and is based upon & titmtion of the alcoholic (or
Card 113 alcohol-beazerte) solution of the substance with caustic potash,

Numbers in Lignite-Like Bitumen Substances
beside phenolphthalein and alkali-blue. In the present paper it is
shown that these indicators as well as the application of an
alcohol-benzene mixture render titration More difficult, whereas
the application of a potenti=etrio metboa in accordance with
GOST 1784-47 is too complicated. Aa blue coloring can be better
observed in titration, tymolphiWein vas investigated as an in--
dicator, for which purpose various weighed portions and alffer-
eat quantities of solvents were used. It was found tlat 0.5 g of-
the substance per 50 ml of alcohol are sufficientp and that theru
ia no neoesaity of uAing a mixture of solvents. A second series
of tests showed; however, that for the purpose of detexmining acids
not more than 2 g of the bitumen substance should be used for
50 ml of alcohol, whereas for the determination of the ester nim-,
ber a weighed portion of from 0-3 to 0.7 g per 50 ml of alcohol
must be used. It was found that ooncentratic.1 of the lye causes an
increase of the values of ester numbers. Saponification for one.
hour in boiling water suffices in order to obtain accurate values,
and on the strength of these investigations it Is reconmended
that methods of determination be precisely described. Data con-
cerning the technique of analysis for the determination of acid-
Gard W3 and ester numbers are given. In this connection the editor says

On the Methods of Determining Aoid,., Ester- and Iodine 32-24-6-12/44

that experiments axe intended to be carried out for the purpose
of testing the method developed by Kaufman, which is used for
the determination of unsatumtea hydraa&rbans in gasoline used
for airomft acoording to GOST 2070-51 for the analysis of
bituminous substances. There are 3 tables, and 2 references, 2
of which are Soviet.

TITLE: A Scintillation y-spectrometer with a Control
Channel
PERIODICAL: Pribovy i tekhnika eksperimenta, 1960, No. 6,
PP. 30 - 34
TEXT: A block diagram of the spectrometer is shown in Fig. 1.
It consists oE a Cal(TI) cr-ystal suvr-ounded by a MSO
reflector. The cylindrical crystal is in contact with two
photomultipliers (one at each end). The output of one of the
photqz~ultipliers is fed into the "working channel" and the
output of the other photomultipliev is fed into the "control
channel". The working channel consists of a cathode follower,
a linear amplifier and a shaping circuit and the control
channel consists of a cathode follower, a linear amplifier and
a single-channel pulse-height analyser. The outputs of the
two chamiels are fed into a gate and the output of the gate is
analysed by a 20-channel pulse-height analyser. The working
principle of the spectrometer as a whole is as follows.
The window of the single-channel pulse-height analyser in the

S/120/60/000/006/007/045
E032/E314
A Scintillation y-spectrometer with a Control Channel
control channel defines the part of the y-spectrometer
which corresponds to the photo peak under investigation.
Pulses from this analyser open the gate which transmits
amplified and shaped pulses from the working channel and these
are fed into the 20-channel pulse-height analyser at the end
of the system. The shaping circuit is necessary in order to
delay pulses leaving the linear amplifier in the working
channel for a time corresponding to the delay in the single-
channel analyser in the control channel. The shaping block
produces rectangular pulses, whose amplitude is the same
as that of the initial pulses. Since the amplitude distri-
bution at the outputs of the two photomultipliers are
independent, only those pulses will be transmitted by the
gate which belong to the photo-peak under investigation,
provided the position of the maximum of the photo-peak
remains unaltered. This device can be used to separate
photo-peaks in a complex spectrum and to detect weak y
activities on a background of strong radioactive contamination.

A Scintillation y-spectrometer with a Control Channel
The resolution of the instrument is 12.5% at o.663 MeV and
10.5% at 1.33 MeV. The efficiency of the spectrometer
for y-rays of 0.633 MeV is 1.3%. Fig. 9 shows a typical
siDectrum obtained for a mixture of
137 58 1 58
Cs and Co . The y activity of the Co component is
1/50 of the activity of Cs137. The curve marked c~_ was
obtained without the control channel and Curve b with the
control channel. A 5 V window 51fas employed. As can be seen,
the small y activity due to Co is easily separated out.

TEXT: Results of fragment yield measurements carried out in 1.953-1955 are
dealt with. u235 and U238 were fissioned by 14.5=Mev neutrons and
fission neutrons. The relative fragment yield with respe-,t to the M099
yield and the absolute yield in Mo99 were determined., Pressed 10-50 g
U308 tablets were put into a hermetically sealed container,
A U 235 multiplication system without a moderator, and a converter which

ABSTRACT: As is well known, industrial alloys of the type mentioned
in the title with raised Si-contents (9-13% Si) are modified-
by the introductionp either directly or in the form of its
salts, of sodium into the liquid fusion. By an appropriate
Na-dosing structural changes or a considerable improvement
of the mechanical properties can be brought about. Howeverg
this phenomenon has not as yet been duly investigated. In the
paper under consideration a brief report is given on the first
part of the work4 conducted by the authors with regard to the
topic mentioned in the title. When an alloy with raised
Na-content is put into watezv small gas bubbles are evolved.
These bubbles, which deflagrate with yellow flames at the
Card 113 surfaced produce a brown film on the walls of the vessel.

On Sodium Double Silicide in Modifiel Aluminum- SOV/20-125-2-22/64
Silicon Alloys of the Silumin Type
The author has developed a special method for the production
of this brown substano--. The chemical and spectrographical
analyzes showed an SiO 2 content of 93.7%. The yellow-brovnish
color was obviously due to SiO (monoxide). It disappeared
when roasted in ai~:q said gas burning with a rather heavy
explosion in the V-shaped vessel. A silicon-hydrogen (silane)
is alleged to have been produced by the interaction with-vater
of the alloy concerned. From all such substances of the
homologous seriee Si nH2n _~ .9 a gaseous tetrahydrite SiH4
is formed~ which is self-igniting in air. Cons-quently it can
be assumed that the reaction took the following courset
SiR4 + 202 ____~=2 + H20. On previous occasions silane
formation (Refs 19 2) had been observed in similar instances
and the formation of an aluminum-silicide of variable
composition had been assumed. However, there had never been
any confirmation of this assumption. The occurrence of sodium
silicide in the alloys mentioned in the title tallies with the
Card 2/3 views, developed by the authorp regarding the formation of a

threefold alloy in the system Na-Al-.Si. The author is of the
opinion that the phenomenon of "trans-modification" is caused
by the formation of a sodium double silicide. This is also to
aecount for other phenomena connected with a raised Na-content
in the alloy, i. e. lowered corrosion resistance; tendency to
fissure formationg changed micro-structure, et al. The author
has obtained a patent (a7torskoye svi6etellstvo Nr 77421,,

TITLE; ~v'hat is over-modification of silumin
PERIOMCAL: 'r--;vetiiyye Slietaily-,,no.ii, 1962, 89-92
I'!-"XT: Th cphenomenon of over-modification is explaii,ted from the
point of view of the physico-chemical analysis of the for 'ination of
a ternar-y eutectic from aluminium, silicon and the ternary
silicide NaAlSi. There are two stages of over-modification:
a slight excess of sodium forming a network structure does not
cause a marked fall in the mechanical properties; a large excess
causes the formation of coarse crystals of silicon and ternary
silic.ide, hair-cracks develop and the inechanical properties fall
sharply. This latter stage is rarely encountered in practice.
A slight excess accumulates in the boundaries of the eutectic,
grains forming a layer of coarse crystals. The impurities not
-soluble in modified liquid silumin and impurities which are
soluble*but are precipitated during solidification also accumulate
in these regions. If the composition of the over-modified alloy
(liffers greatly from the ternary eutectic composition, a large
6ard 1/ 3

S/1361//62/000/011/002/002
'.."hat is over-modification ... E021/E435
amount of products of primary and secondary solidification will b6
formed, as a result of which the spherical shape of the eutectic
grains will be destroyed. The second stage of over-modification
is characterized by the Cormation of streaks along the edgres of
which accumulations of grey crystals are formed and adjoining them
there are parts of the aluminium which are almost free from
silicon precipitate, after which the usual modified microstructure
begins. It is proposed that this arises because a large excess of
sodium will give an alloy which, in the liquid state, is in the
region of stratification. Thus, part of the sodium will be in the
form of an alloy and part will be in the form of an emulsion.
Some of the sodium will coalesce to form small droplets. During
solidification, the sodium droplets will be redistributed as
films in the outer parts of the grains. Then, as a result of
diffusion, the liquid sodium will interact with the silicon in
the solid alloy to form binary and ternary silicides (NaSi,
NaAlSi). When polishing and etching of a specimen in such a
condition in an aqueous medium, the sodium and the binary silicide
will be leached out, leaving small cracks or pores in the specimen.

TITLEa The Investigation of a Shower Produced by a Singly Charged
Particle of High Energy (Issledovaniye livnya, vyzvannogo

PERIODICLAs Zhurnal Eksperimentallnoy i Teoreticheskoy Fiziki, 1958,

ABSTRACT: The case described here of the type (2 + 16 P) was observed
in a 600 tL thick emulsion Ilford G-5, which in 1955 was
exposed in Italy at an altitude of about 30 km. The energy of
the primary particle which was estimated by the-usual kine-
matic method was (5+10) .1012 eV. The shower particles moved
-3 _1
within an angle of 10 .10 rad. The central traces pass in
a plate distances up to 5 cm. For this very reason the ener-
9Y Of 15 shower particles could be determined by immediate
Card 1/4 measurement of the multiple Coulomb scattering. The first

paragraph discusses the measurer.,ent of the momenta of the se-
gondary particles. The scattering was measured individually
Ibr all shower particles. The value D of the scattering, which
was measured immediately in the experiment, is composed of
the pure Coulomb scattering D and of the scattering n,
which is caused by all the otLr factors. The quantity n can
be measured by measurement of the scattering of a high energy
particle at three cells along its trace. The scattering of
the shower particles was measured at cells from 500 to 4000
The next paragraph deals with the angiar distribution and the
energy - distibution. of the shower particles. The angular
distribution of the shower partides is illustrated by a dia-
gram. This angular distribution agrees best with distribution
according to'the'llei4an6urg the'ory. . To compare the energy
distribution of the shower particles with the theory by Lan-
dau a histogram was constructed in the laboratory coordinate
system. The here found energy distribution does not correspond
with the Landau theory, for a predominance of the low energy
shower particles compared with the expected theoretical values
is observed. The measured energy of the particles is smaller
by one order of magnitude than the the corresponding-theoreti-
Card 2/4 cal values. A diagram illustrates the energy distribution of

Energy
15 shower particles in the center of mass system. This curve
corresponds to the energy spectrum of the Heisenberg theory.
The coefficient of the non-elasticity in the center of mass
system amounts to +0.06
0110 -0,02. The 'shower investigated here
obviously has been generated by a nucleon-nucleon collision.
The third paragraph discusses the soft component,which accom-
panies the shower. To study this soft component the emulsion
was evaluated inside a cone with the half aperture angle of
0.15 rad relatively to the shower axis. In this volume 10
electron-positron pairs and I trident were found. The corre-
sponding data are compiled in a table. In case.of knowledge
of the number of the primary electron-positron pairs, which
accompany a given shower, the expected number of neutral
pions can be computed by application of the law of radioactive
decay; a corresponding formula is written down here. For the
mean energy of the neutral pions the value 15 � 3 BeV is found.
There are 6 figures, 4 tables, and 14 references, 4 of which
Card 3/4 are Soviet.

EVALUATAG T 11B ENERGY (E 10 ev) OF PRIMARY
PARTICLES FROM THE ANGULAR 01D RINERGY DISTRIBINION
OF SECONDARY SH014ER PARTICLES
E. G. Boos, Zh. S. Takibayev
It brief ecrsideration is I.,,iven to the more co,,Imon methods of determining the
energy'of prims:ry cosmio-ray shower~producing particles in individual acts of interac-
tion from the aneular distribution of the secondary particles. It is noted
that the generally used kinematic methods are based on assutptions which in the
majority of cases are not corroborated by experimental data concerning the energy and
angular distribution of shower particles.
A method is described of evaluating the Lorentz factor in the center-of-mass
systemic- , in -which use is made of the experimentally observed distribution of
of,-transverse impulses of secondary particlesp The values offithus obtained
concide (within 'the limits of errors) wJ th the values of AC" evaluated from the
angular distribiiti.on of secondary particles on the assumption of a power ( /--,
IA~ energy spectrum of the generated mesons. iccount of the energy spectrum of
secondary particles systematically leads to smaller values of tc- . Insofar as
the distribution of transverse imDulses is such that -Pi - C and the separate
values of p do not greatly differ from this mean valije, it becomes possible to
evaluate the energy of the primary particle by the angular distribution alone, by
introducing a certain constant factor that takes into account the natiire of the
distribution of PC, -

In evaluating.?L , account is also taken of the energy spectrum of the
shower-prod,icing particles. This results in an additional reduction in the value of
rc_- The problem is considered of evaliiatinp the energy transferred to the
Fenerated mesons and the effect produced by the fraction of heavy mesons up on
the magnitude of this energy. The energy of the primary particle has been
correlated with the energy transferred, on the average, to the 1-enerated mesons.

In Eq (2) there are three unlmoimas, namely, the momentum PPC
and the quantities a and x . To determine them it is
necessary to have three equations (,orrespondin- to three cell

solved in the case of cells whose len-ths are in the ratio
