ABSTRACT: A decay of hyperons into nucleons and leptons (of the kind
Ao -;' p + e-' +:~r) has hitherto not been observed, which is
in contradiction to the assumption that the constant F of
four-feruion interaction, which is responsible for this
kind of process, is the same as in the ordinary P-decay
or in muon decay (G = 1.41.1o-49 erg..CM3). A decrease of
F may occur as a result of either its renormalization due
to strong interaction in hyperon decay, or because of the
difference in the non-renormalized constants, In both cases
estimation of F is of interest. This is possible by esti,at-
the probability of K and K decays, which is brought

TEXT: The p + e + decay has hitherto been observed experiment-
ally only twice., whereas theoretically, according to the universal
VA-interaction., the frequency of its observation ought to be about
20 times as great, As the investigation of this process is rendered ex
tremely difficult by the rarity of its occurrence~_the author suggests
that instead, the reverse process e" + p -) A+ ~ (1) be investigated.
In the laboratory system, the threshold of this reaction is at 194 Mev,
and up to the A .-photoproduction threshold (912 Mev)-, A-hyperons are
produced only according to (1) (or according to the mode e- + p -* 2:0+ 9;
7- 0 - A + y)~ A general formula is obtained for dc, which can be con-
siderably simplified for a "pure" VA-interaction, This general formula
represents dc as a function of the form fac'.ors C V CAY BV and B A , as

T--',,'.T: The experimental verification of unitary 3-fold and 8-fold
symmetry in strong interactions in the Sakata model is discussed (M. Gell-
Mann. Symmetries of Barions and Mesons (preprint), The Eightfold'Nay
(preprint)). The 27 amplitudes of meson + nucleon . 3imeson + baryon
processes, which are independent from the standpoint of isotopic in-
variance, are written down; likewise, the 21 amplitudes of the baryon
+ nucleon baryon + baryon processes. For the unitary 3-symmetry,

is valid for the first case, and -1
(4) in the second. In the case
of 8-symmetry, only five of the 27 amplitudes of the first process. and
only three of the 21 amplitudes of the second process, are independent.
Up to date, no experimental data are available on the cross sections of
strong-interaction processes. Therefore, it cannot be decided which of
the above results is of physical importance. Data are available on the
cross sections of elastic and nonelastic processes of a few Bev, which
occur in collisions of mesons or baryons; data are also available on
total meson-nucleon and baryon-nucleon cross sections. These data must
deviate from the results obtained here; the extent of these deviations is
discussed. There is 1 table.

TITLEt Effect of form factors on the relative probability for
lepton decays of hyperone
SOURCE: Zh. eksper. i teor. fiz., v. 47, no. 1, 1964, 262-269
TOPIC TAGS: lepton, hyperon, particle interaction, muon, electron,
probability, baryon, strange particle
ABSTRACT: It is shown that the-ratio of the total probabilities
of muon and electron decay of hyperons, W 1W is sensitive to the
~L e#
contribution of certain form factors. In the absence of form fac-
tors, the theory predicts this ratio with accuracy of approximately
1%, independently of the values of the weak-interaction constants.
If the form-factors are small, the theory likewise predicts a defi-
nite value of this ratio. Any deviations of this ratio from the

theoretical" value characterizes the role of the form factors of
the decay interaction and is not likely to exceed 30%. The results
are valid if the decay interaction is the same for electrons and
for muons, in decays with change of strangeness, and if the baryon
current is a component of the isotopic vector in the case of strange-;
conservation. it is also assumed that the decay interaction
includes only the V and A variants. Comparison with experiment
yields for the ratio of the probabilities of the decays Z--.* A + e

ABSTRACT: Continuing earlier work by one of the authors (Shekhter,
with Ya. I. Azimov and A. A. Ansel'm, ZhETF v. 44,, 361 and 1078,,
1963) on the determination of the explicit form of Regg-e-pole tra-
jectories, the authors extend the analysis to a more complicated
case, when the reaction can proceed via several channels. The spe-
cific problem considered is the behavior of Regge pole for scatter-

ing by Yukawa potentials when the reaction has two possible channels.
The analysis is carried out by the same method as in the earlier
work. The equation for the pole trajectories is first obtained in
the case of weak coupling, followed by an examination of the 2be-
havior of trajectories at not too small negative values of k 1 and
2 2 2
k2 Further motion of the poles at small k 1 or k2 is described,
as well as the behavior of the trajectories for positive values of
k (k = momentum). The analytic properties of the trajectories are
then described and the occurrence of so-called M-poles is discussed.
It is shown that at high energies two trajectories, corresponding to
number of channels, arrive at each integer negative point. The vari-
ation'of the trajectories with energy is essentially thesame as for
the single-channel problem. The increase in the.number of trajec-
tories causes also an increase in the number of their collisions,
i.e., the number of branch points in the complex energy plane. it
is concluded that all the earlier results can be easily extended to

ABSTRACT: From the recently reported resonance with mass 1710 Mev (T. G. Schumann,
P'hys. Rev. Lett. v. 15, 531, 1965), doserved in the pi&nO system, it is deduced
that the decuplet which contains this resonance should also contain a resonance
with strangeness -3, namely n-(1875)- It can be observed as a resonance in the
reactions of the type K- + p + zz- + kO + e and :-~D + IC + 10 + e. The author
estimates the width of this resonance and finds it to be approximately 13 Mev,
using relations that are valid when account is taken (to first order) of the in-
teraction that breaks unitary symmetry. It is pointed out that the experimental
values of the partial widths and the accuracy of the approximation used is not

esu~mate. The energy released in the decay n-(1875) k is quite small, so
Uhat a much smaller width could also be reasonable. It 1.9 shown in the conclusion
that if the assumed existence of the other members of the same decuplet is verified.,

;,~entally. However, the results would still be highly sensitive to even small

PERIODICAL: Avtomobillnaya promyshlennost', 1958, Nr 6. PP 34-37 (USSR)
ABSTRACT: The author describes various aluminum alloys used for the bodies
of automobiles. Tables 1 and 2 show alloys used in the USSR.
Of these,the avial and duraluminum are thermically strength?ned
and their mechanical properties are 1-iven for the annealed as
well as for hardened state after the natural aging period. The
strength of other alloys can be increased only by riveting and
they are either annealed, semi-cold hardened or cold-hardened.
The comparison of different makes of alloys in the USSR and
abroad showed that for automobile bodies the aluminum-magnesium
alloy is the most suitable, which possesses a high degree of
toughness even when annealed. The author deals with the forg-
ing processes of bodies and body parts, and establishes the
conditions in which the best results will be obtained.
There are 4 tables, 3 photos and 1 graph.

ABSTRACT: There exist only extremely scanty published data on the spread of deform-
ation through the bottom of a forging during extrusion. In this connection, the
author undertook to determine the deformation characteristics during cold inverted
extrusion on taking into account the concomitant bottom upset of the forging and the
decrease in the cross sectional area of the forging. On this basis a formula for de-
termining the overall degree of deformation due to inverted cold extrusion is derivvd-

ABSTRACT: The authors investigate non-stationary hydraulic processes occurring in a
4liquid-metal meter with electromagnetic induction pump at constant input pressure.
The purpose of t investigation is to permit efficient design of such devices. The
operation of the meter is divided into fivv states (filling of the working channel
of the pump,~raising the metal verticallyp motion of the metal horizontally., flow
of metal with the pump turned on, flow of metal by inertia after the pump is turned
off). The differential equations of flow are written out for each of these stages,
and analytic solutions are obtained for this last two stages of the flow. It is shown
that by preparing a set of curves representing numerical solutions of these equations
it becomes possible to choose the proper diameter of the metal pipe and the operating
pressure, as well as to estimate the hydraulic resistance and other losses. Formulas
which make it possible to estimate the structural parameters for known pu* charac-.
teristics are also presented. Orig. art. has: 5 figures and 6 formulas.

TEXT: At the "Neftegaz" works in Moscow an antiwear sulfur additive
(HT- -103 NG-103j) and an antioxydant additive containing sulfur and
phosphorus (Wr -105 [NG-105], -105a NG-105al Rr -105d L-NG-105bJ
for engine oils were developed from the products of heat-contact cra~cking
of kerosine. Products from the cracking of paraffin, distillation
residues and kerosine were used for synthesizing the sulfur additive; the
130-2500C cracked kerosine fraction was found to be the best raw material
for producing the additive. Sulfuration was carried out in an experimental
unit by adding the cracked stock to melted sulfur (15% on cracked stock)

under intense agitation; the temperature was held at 135-1500C, and the
reaction time was 2-3 hr. The resulting sulfarated product was held for
8 hr at 150-1600C after which it was washed in a column, at first with a
solution of Na,,S and then with NaOH. After passing the copper-plate test
the prodVel was charged into a vacuum column and the hydrocarbons which
had not f~ken part in the reaction were distilled off from it at a
residual pressure of 5-10 mm H9; the product was subsequently taken to an
ultracentrifuge. The yield of additive was 25-30% of the raw material.
Comparative Zests on the additive NG-103 showed that as regards antiwear
properties it is not inferior to -33-5 (EZ-5), OT-1 (OT-1) or Of/9 (L Z6/9)
which are made from scarce raw materials, and that it has advantages over
them (cheap source material, simple production method, no unpleasant
odor). The aniioxydant additive was produced from a"75-2500C cracked
kerosine fraction with a molecular weight of 198 and a Francis bromine
number of 40. In order to produce a stable oil-soluble additive the
olefinic hydrocarbons of the cracked stock were first polymerized in the
_:-reserce of 2 wt.;-1Q" AlCl3(on raw material) at 600c. The mixture obtained

material) with agitation. Upon completion of phosph=salfuration the
temperature of the mixture was raised to 140 0C and held there for 7-8 hr.
The product was then treated with 5'~ H 2so4 and washed with water. The
hydroc4rbons which had not undergone reaction were distilled off from the
purified product at a pressure of 5-6 mm Hg. The acid additive(NG-105)
was neutralized with CaO (XG-105b) or ZnO (NG-105a) and was centrifugalized.
The additives so produced were dark brown in colour and had the usual
'odor of cracked stocki in a thin film they were transparent. The
additive yield is 25~L of the initial cracked stock. lAbstracter's note:

and nitric acid jor a. jnp~ture of sulfuric and nitric. acid) require a contact time of 3 hrs. at~
no less than 70C. Using a 1:1 proportion of oil and nitrating agent, the yield of nitrocom-
pounds mounts to 25-0.0%. After the above research, a pilot plant installation was de-
signed (there is a complete description and flow diagram in the article) and put in opera-
tion. The -products were succeBSfUDY tested by adding them to bigh-sulfur diesel fuels.

ABSTRACT: In order to stabilize fuels antioxidants are added to them. ~rhese
antioxidants prevent the formation of oxidation prbducts in gagolines.)N These
substances are not corrosion inhibitors, i. e. they do not protect the metal from
destruction in the presence of water. The corrosion of metal is developed not
only because of the action of dispersed water, but also because of increased ag-
gresiveness of mercaptans, disulfides and sulfides. Consequently, along with
antioxidants it is necessary to add corrosion inhibitors to fuel. It was establish-
ed that combinations of the majority of oil soluble corrosion inhibitors are more

effective than any single one of them. Thus, a mixture of three substances, con-,
taining sulfo groups, nitro groups and amino groups surpass, in terms of protect-
ive efficiency, sulfonates, nitrooils or amine containing corrosion inhibitors.
As a result of the conducted work on the selection of composition two combination
additives were selected: KP-1 and KP-2. KP additives are produced by mixing
acid sulfo and nitro products. The production technology of mixed additives is
simpler and the quality of products is better. Data were obtained which show that A
during combustion of sulfur containing diesel fuels the maximum corrosion
of
steel occurs both at lcm(100 C) and high (500 Cor higher), temperatures. Under
these conditions during combustion of fuel without additive the- whole surface of
the tested steel plate is subjected to corrosion, the plate darkens and corrosion
spots occur on it. During combustion of fuel with KP additives the surface of the
plates remains as clean and shiny as beforet the test. Orig. art. has: 2 tables

ABSTRACT: The feasibility was shown of producing large quantities of a grade of
finely divided MOS2 suitable for lubricant additive purposes. A newly built ex-
perimental unit was used which performs comminution and subsequent classification I
of MoS2 in the form of an aqueous ethanol- suspension in an ultrasonic size-reduction
machine'and an ultrasonic classifier (Fig. 1 and 2 of the Enclosure). It is notedi
that conventional mills are unsuitable for producing M052 of the desired purity I
and particle size. The source of ultrasound in both, cases is a wapetostriction
transducer. The classifier screen is cotton cloth. The end product particle size
is less than 1 micron. On the basis of this ultrasonic equipment,'a flow sheet is
proposed for a semi-works plant designed to produ6e MoS2 as a sus"nsio'n in.aqueolu
alcohol, a product designated DMVS-l. Orig.,art. has: 4 figures. [SRI
