in contradiction to the assumptions of the statistical theory on the
isotropy of the angular distribution of secondary particles in the
c.m.s. The mean proton and pion numbers (n p and n 71 ) occurring per in-
elastic pp-scattering event in the rear semi.-space in the c.m.s. in

and charged pions from pp interactions. It is shown that the pion spec-
trum with respect to the the3retical distribution is shifted toward
smaller, and the proton spectrum toward greater momenta. The average
momenta in the c.m.e,, are calculated to be P " - (1..2+0.1) Bev/c and

of 58%). Fig. 3 shows the angular distributions of the charged secondary

distributions (pp interaction) are symmetric in the c.m.s. The angular

TEXT: This "Letter to the +Editor" presents preliminary results of a study
of the reaction n- + P -4n + n- + n, in which the initial meson had an
energy of 245115 Mev. The experiments were performed in the synchro-
cyclotron of the Laboratoriya yadernykh problem OIYaI (Laboratory for
Nuclear Problems of the Joint Institute of Nuclear Research). A total of
32 events have been recorded. The cross section for the reaction was found
to be 0.10 t 0.04 mb. The meson production near the threshold can be
explained according to A. A. Ansellm and V. N. Griboy who have shown that
the energy dependence of the cross section depends on partjlzle interaction
in the final state and is determined by the amplitudes of the charge-
exchange reactions n+ + Tt--:~n 0 + no and n+ + n--+no + p. The angular and

TEXT: The first results obtained from the investigation under review
were submitted by B. M. Pontekorvo in July, 1959, at the Conference for
the Physics of High-energy Particles hold in Kiyev. The authors of the
present paper wanted to study the conditions and the energy characteristic
of secondary particles in the reaction R- + P --w I- + R+ + a at an energy
of 290 Nev of the primary x--mesons. The angular and momentum distribution
obtained are compared with the statistical theory by Fermi and the iso-
baric model by Lindenbaum and Sternheimer. The meson production was
conducted in pellicle stacks, which were exposed to a x--meson beam from
the synohrocyclotron of the Laboratoriya yadernykh problem Ob"yedinennogo

were recorded in the photo*mulsion, and in the further analysis only such
oases were selected as exhibibd only two mesons among the secondary
charged particles. 135 interactions satisfied these conditions and in
them, the authors measured the energy of the secondary mesons and the
angle of their emission. An estimation of the reaction cross section, in
which reference was made to a paper by K. S. Bogomolov and M. F. Rodicheva,
yielded a value of (0.61 + 0.13) inillibarns. Fig. I is a graph depicting
the momentum distribution7of secondary particles in the studied reaction
for n-mesons and neutroneo In these diagrameg measurement results are
compared with the curves calculated after the statistical theory and
the isobaric model. Theory and experiment agree within the limit of
error. The diagrams of Fig. 2 show the experimentally determined angular
distributionsfor n+-mesons, n--mosons, and neutrons. Hero, the non-iso-
tropic and asymmetrical angular distribution of the reaction products does
not agree with the premises of the statistical theory. It follows from the

TEXT% The present paper is the continuation of a previous paper (Ref. lt
DAN SSSR, j-22, 52. ',';60), in which the authors studied the momentum +and
angular distributions of seccndary particles of the reaction t-+p r + T-+n.
In the present paper, the authors present the results of an analysis of 250
events of this reaction at a meson energy of (290+.15)Mev. The studies were
made at the synchrocyclotron of the laboratoriya yadernykh problem OIYaI
(Laboratory of Nuclear Problems of the OIYaI) by means of a photo-emulsion
chamber. The measured momen-;um and angular distributions were compared with
those obtained by the statis-:-ical Fermi theory and the model of Lindenbaum -

approximately 5%, Results ara illustrated in figures. A comparison of the
diagrams shows that no quantitative agreement with the experiment can be
obtained although the statistical theory and the isobaric model correctly
reproduce the characteristic features of the spectra. E. g., the maximum
of the neutron spectrum (Fig., 1) was found to be shifted toward smaller
momenta. The angular distribution (angle between secondary pions - Fig. 2)
indicates that the mesons probably depart at larger angles than those found
theoretically. The mean angles of emissicn are the followings

has.been shown earlier (ZhETF, R, 506, 196o) that the distribution with
respect to relative momenta of secondary particles is in agreement with the
theoretical distribution calculated by A. A. Ansel'm and V. N. Gribov. In
this connection, the authors assumed the production of an additional meson
near the threshold. On the basis of this theory and by taking account of
the interaction of particles in the final state, better agreement with the
experiments can be obtained alsc, at these energies. Using the matrix element:

TEXT: The reaction 7,- + p --vn + + n- + n was studied in a photoemulsion
chamber- at a mean primary pion energy of 240 + 15 Mev. The mass spectrum, of
the n+n system was taken in the interval bet7ween 280 and 350 Mev. Ou t oil

pions came to rest in 85/~ of the events; thpir*energy was determined from
the track; in the remaining 15~ 6he meson left the chamber. Its energy was
determined .11rom the ionization. The measurement accuracy of the mass of .
the n+n- system was 1.5-3.0 blev. As compared with the phase volume of all
events recorded in the chamber, the experimentally determined mass spectrum
is shifted systematically to the side of ,the higher mass values. If the
experimental data are divided by the phase volume at the correSDonding
points it follows that the matrix element inareases with increasing energy

of the n+n- system and that it does not cnincide with the phase volume. The
d~.viation of the mass spectrum from the random distribution is ascribed to the
interaction of the pions in the final state. No resonant-type anomalies
could be observed in the mass spectrum of the n+n- system within the measure-
ment accuracy in the interval between 280 and 350 Mev.
Hence the upper limit
of the total production cross section of the A.BC meson with the mass
300 + 10 Mev does not exceed 10-29 cm2 in the reaction (1). In the reaction
p + d - He3 + a + n the deviation of the experimental spectrum of the He3
nuclei from the 3-particle phase volume is assumed to be due to a dependence
of the matrix element of this reaction on the mass of the n+n- system.
Also in this reaction, no resonant-type anomalies were observed. Hence
the authors conclude that the anomaly is not caused by the formation of a
new particle or of a resonance. There are 3 figures.

ABSTRACT: The spectrum of the output of an ideal limiter was
investigated in Ref 1. This article extends the inve--tication
to a limiter which has an arbitrary characteristic. It is
assumed that at the input to the limiter acts at a voltage uBX
with a slowly changing amplitude and frequency:
uBX = UBX(t)coslwt + (P(t)3 (I).
The voltage at the limiter output u0 will have a different
amDlitude Uo but the same frequency as the input voltaEe,
i.e:
U0 = UoMcos LWt + (P(t)] (2)

Eq.(2) and the relationships which follow from it are true
because a filter, which passes the instantaneous frequency
component w + (p'(t) but does not pass the frequency comm-
ponents n(w + ~pl) , where n = 2, 3, etc., is connected to
the output of the limiter.
For an ideal limiter U 0 is consLant but, in practice, U 0
changes with time and in general the output spectrum. can be
considered as the spectrum of an amnlitude-frequency-modulated
voltage.
Dividing Eq.(2) by (1), we obtain:
U0 = UBX(t) 'BX (3) -
The output voltage differs from the innut voltage by

function U 0(t)/UBX(t) - Therefore, the output spectru;,,-. cari

i.e. the spectrum of the output voltage equals the sum
of the two spectra of amplitude-modulated oscillations.
The advantage of this method is that it is not usually
difficult to calculate the spectrum of an amplitude-modulated
voltage.
SubstitutinS in Eq.(?), the value of the Fourier expansion

the spectrum at the output of the amplitude limiter when
a beat acts at the input is obtained:

Expressions show that the amplitudes of the spectrum
depend on the amplitude characteristic of the limiter.
The effect of a beat on a limiter with a polygonal amplitude
characteristic is next considered. The polygonal function
is considered as the sum of a constant number and a finite
number of elemental polygonal functions (Ref 2). The elemental
polygonal function consists of two straight lines, one of
which lies on the abscissa. For example, the polygonal
function denoted in Figure 2 by the points 0, 11 2 can be
presented as the algebraic sum of the two elemental
polygonal functions 0,3 and 0,45 -
Thus, the amplitude of the voltage U 0 at the output of a
limiter which has an amnlitude characteristic convisting
of N linear segments ZFigure 1) can be written in the form
of an Amplitude Limiter

Figure 5 shows that additional components appear at the output
and that the output spectrum is always wider than the input
spectrum. The form of the output spectrum depends on a .
When a = 1, the spectrum is much wider and more sy=-.etrical.
The effect of limiting on the magnitudes of the spectrum
components is considered, assuming an amplitude characteristic
as shown in Figure 4. The degree of limiting is character-
ised by the coefficient c , as defined in Eq.(28). Here,

section of the second part of the characteristic produced

ABSTRACTs This palper investigates the effect of weak pulse inter-

produces a transient process with a maximum amplitude
smaller than that of the intelligence signal) on a frequency
modulated receiver with various high-frequency and low-
-frequency filters with a random signal-frequency at the
moment of the interference effect. It is assumed that the
froquancy modulated receiver conaists of a high-frequency
filter, a frequoney detector and a low-frequency filter.
The transmission factor of the high-frequency and low-
-frequency filter is assumed to be equal to unity with
medium frequencies. Tho effect of the kind of filter in the

TITLE: F.m.-Discrimination and Amplitude Detection of Beats of Two
Harmonic Voltages
PERIODICALt Elektrosvyazl, 1960, No. 11, PP-3 - 14
TEXT: When analyzing various problems and, in particular, the noise-
proof feature of radio receivers, it is necessary to determine the time-
dependence and the spectrum of the voltage at the output of a f.m.-discri-
minator or of an amplitude detector when beats occur at its input. This
determination is well-known in the case of an ideal f.m.-discriminator and
of an amplitude detector without limiter. But the more general case of an
unsymmetrical f.m.-discriminator with a non-ideal limiter has not been
given sufficient attention in technical literature. An analysis is usually
effected, in this more general case, with the aid of the frequency charac-
teristic of the discriminatcr, and this method is not strictly correct when
a non-ideal limiter is used. The author undertakes therefore to work out
formulae allowing to determine the timedependence, the extreme values and

ABSTRACT: In numerous tests on the chemical protection of nuclei,
against the photodynamic effects (Phd. E.), the authors have
established a powerful protective of hyposulphite (bblel).
In a test with X-ray irradiatijii, however, the protective
effect could not be observed (%ble2). One may say that the
protective mechanism of hypoaulphite by Phd. E. is not
necessarily connected with fla-3 oxygen-neutrali2ation.
Previously (Ref 2) a certain similarity of the Phd. E. with
the results of the water radiclysis through ionized radiation
was indicated. Here also a free HO 2- radical is formed as end
effect, although in another way. The tests, carried out by the
authors, have shown that hyposulphite protects either, against

the ionized, and the normal statso of the oxygen molecules,
whereby there is a difference in tha protective effect of the
hyposulph,teS against the Phd. F. on one hand and against the
X-ray irradlatJon on the other. Tit.to-uran is effective
against ionized radiation, but offers no protection to the
chromosomes against Phd. B. (Ihbig) '1. One must admit that the
protective effect of the thio-,;rea is not connected with the
neutralization of the free F10 2__,alicalt, if it arises by the
X-ray action as well as wi%h zhe F. Although this
conclusion seems to contradle, I-'.,s cpin_;.o-i about the
role of the thio-urea in radlj*,-~'Li~-or,_Iiil effects, it may

are,as a rule, active, whereas the pigments which are not

authors beefime aware of the fact that hyposulphite

reaction, and goes parallel to the latter process. The
authors have tested, as protection against Phd. E. several
luminescent oxtinguishers (KJ, KBr, hydroquinones) under the
application of rivanol and methylene-blue WU 4). M. I.
Mekshenkov has verified the contrasting v:lue of the authors'

ABSTRACT: The photodyaamic process of visible light causes a great number
of re-arrangements of chromosomes. The analysis of the after-
effect of irradiated solutions of coloring matter is of great
interest fcr the explanation of the nature of this phenomenon.
The aftereffect mentioned, was found in the hemolysis (Refs 1-5):
weak solutions of fluorescing colors showing no darkness reac-
tion, can ondanger erythrocytes after they have been expooed to
light, while the effect itself takes place in darkness. The
question axose, whether re-arrangements of chromosomes could be
achieved through solutions treated in the described way. As
test objects served the roots of onions treated in darkness
with solutions of Rivanol or toluidine-blue which had been ex-
Card 1/3 posed to light before (Table 1). A remarkable increase of re-

The Genetic Consequence of the Aftereffect of Visible Light
arrangemento of chromosomes was noted in all experiments. The
degree of the aftereffect can be considerably increased by
certain additions (boric acid) (Table 2). This supports the idea
that in this case the mutagenic effect of the coloring matter
is related to come sort of long existing combinations which
develop und~ar the influence of light. These can neither be the
effected molecules of coloring matter nor the active radicals
OH and HO 2' Table 3 shows the results of additional experiments
which were ineant to show the consequence of the aftereffect at
different moments after the exposition to light. As can be seen
from this, the consequence of the aftereffect lasts 15 min but
completely disappears after 30 min. The life of the mutagenic
factor seems to be 15-20 min after the time which the dyestuff
needs to penetrate into the root has been deducted. The authors
give a survey of the work on the mutagenic effect of the ir-
radiated medium on microorganisms (Refs 7-11). In reference 10
the conclusion is arrived at that the mutagenic effect of the
medium treated with H 202 or with u.-v.-rays is related to the
Card 2/3 development of organic peroxides. This is also proved in ref-

SOY/20-126-1-49/62
The Genetic Consequence of the Aftereffect of Visible Light
erences 12 and 13. The authors assume that in the case of an
aftereffect of visible light, the mutagenic effect is related
to peroxide products. The latter develop due to the addition
of molecular oxygen to the color molecule. These are the so-
called photo-oxydes, the existence of which has been chemically
proved in the cases of certain dyestuffs (Ref 14)- In this work
the authors have proved at least three different mechanisms of
the mutagenic effect of color molecules: a) The effect of ac-
tive radicals (photodynamic effect), b) the effect of photo-
oxides (aftereffect of irradiating color molecules with visible
light), and c) probably a direct reaction of color molecules
with the nuclein (darkness-reaction). There are 3 tables and
13 references, 2 of which are Soviet.

ABSTRACT: Considering that the experimental proof of the radiobiological
effect of free radicals is of greatest importance for the whole
theory of the primary radiation effect on living cello, the
authors carried out the following experiments. Chromosome
transformaticn in the calls of bulbs is caused by an influence
of free radicals produced by a chemical process in the cell. The
first experiment was carried out by introducing bivalent iron
and hydrogen into the cell. It is known (Refs 21, 22) that'OH-
and HO 2 radi--als develop under these conditions. The occurrence
of OH and HO 2 radizals involves Btrongly oxidative properties of
Fenton's reagent. In the first test series frequencies of
chromosome transformations were investigated in five control

PERIODICAL: Doklady Akademii nauk SSSR, 1960, Vol. 133, No. 1,
pp. 221-224
TEXT: The primary effects of radiation are caused either by the energy
which is absorbed within the molecules of the structure to be changed
(direct effect), or by free radicals, which form in the solution an a
result of water ionization (indirect effect). These criteria were, however,
refuted by the proved effect of radiation on water-free polymers. The
authors were able to analyze directly the r8le of direct and indirect
radiation effects, since the genetic activity of the free radicalsp which
were produced cheffically in the cell (Ref. 15), was proved. The authors
wanted to discover the chemical protection against the OH-radicals, which

forms on electron transmission in reductive systems. The use of the same
protection against the ionizing radiation must extinguish that part of
the protection which is activated by the effect of the radicals forming
through the ionization of the H20 molecules. The authors have proved a
chemical protective action (Ref. 16) through hydroquinoneg iodine ion,
and other substances. But they were unable to characterize the chemical
protective effect until they had chemically produced free radicals in
the cell. The Fenton reaction takes place as follows:
Fe2+ + H202 )Fe3+ + OH- + OH. The iodine- and bromine ions introduced
into the small roots of onions suppress the genetic effect of both the
Fenton reagent and the mixiure of ascorbic acid with H202. The iodine ion
does not shield the chromonomes against conversions (Table 1). The Fenton
reagent is genetically mort! effective., Ascorbic acid alone, as acceptor
of free radicals, is able -1--o shield the chromosomes. The iodine ions
raise the whole effect of the free radicals from the latter reaction
(100%), and leave about half of the free radicals in the Fenton reaction
unbound. The iodine ion binds on the one hand the free hydroxyl radicals

in this reaction, and on the other hand raises the number of free
radicals, converting divalent iron into trivalent. From their experiments
the authors could not confirm the statements that the reaction of
trivalent iron with H202 *.eads to the formation of a chromosome conversion.
At the same time the mutntion process can be initiated by the solution
of trivalent iron with H2()2, which has no genetic effect (TabLe 4). Thio-
urea shields the chromosomes against direct and indirect radiation effects
(Table 5), whilst shieldin3 them against the chemically produced free
radicals. Thio-urea does :act, however, shield against H202, In all cases
the effect takes place inside the cell nucleus. Iodine ions and quinone
shield the molecules at low concentrations (experiments by V. I.
Mekshenkov). It follows from the results that the main effect during
shielding against ionizing radiation is direct. The genetic effect of the
radiation is predominantly bound up with the direct effect of the energy
on the chromosomes. Finally the authors indicate promising directions
for research. There are ( tables and 33 references: 6 Soviet, 7 British,

ABSTRACT: The aim of the work described in this paper was to
develop a method of corroSion tests under stress pertaining
in steam superheaters and steam piping. The austenitic

it was neces:3ary to reproduce the effect of all the funda-
mental operational factors pertaining inside steam genera-
tion equipmeat. The experiments were carried out by the
method of re3ording the curves of long duration corrosion
strength using a UIN-5 test machine, a sketch of which is
shown in Fig.1, p.27. Due to the hiSh demands regarding

welded joints. A tubular specimen was used for combining
the functions of the autoclave and the specimen (invention
of the authOr.3 of this paper). During the manufacture of
the specimen transverse scratches on the internal surface
were eliminated by lapping by hand. The tensile stre's-ses
in the specimen viere produced by the tensile forces of the
machine and b.T means of internal pressure. The influence
was investiga-ped of mechanical stresses, of the composition
and concentra"U.-ion of the solutions, and of the influence of
heat treatmen-4. The graph Fig.2 shows the results of long
duration corrosion strength tests on the investigated boiler
type austenitic steels. In Fig.4 the dependence is graphed'
of the time to failure of a specimen on the concentration
of a solution of NaOH (stress: 30 kg/mm2). In Fig-5 the
dependence is graDhed of the iime to failure of a speci-
men of the same steel on the concentration of NaCl in a 3%
solution of NaOH. In FiC.6 the dependence is graphed of

the time to failure of a specimen on the test temperature.
The tests carried out by means of the technique for testing
the long duration corrosion strength of austenitic steels
in aqueous solutions at elevated temperatures and pressures
allow the following conclusions to be made: (1) The steels
lEhMN12T, 1Khl8N9T and B1257 tend to corrosion cracking
in alkali solutions (the character of the failure is pre-
dominantly transcrystalline); this tendency is greatest for
the steel E1257 and weakest for the steel lKhl8Nl2T.
(2) Of all the investigated steels, the corrosion 0 cracking
in a pure distillate with access of oxygen at 100 C occurred
only for the steel E1257 during the tests lasting 1000 hours.
(3) The action of the pure distillate at 3000C for 500 hours
with a limited access of oxygen did not cause corrosion
cracking of the investigated steels. The solutions of NaCl,
Na3PO 41 Na2HP041 Na2SO4 , Na2SO3 in absence of oxygen or in
presence of a limited access of oxygen, do not cause corrosion
cracking of austenitic steels. (4) The concentration curve
of long duration corrosion strength of austenitic steels in
0
alkali media does show a limit. Thus,the critical concentra-

tion of alkali for the steel lKhl8N9T at 2100C and
a -.30 kg/mm,-~ is 3% and at 3300C it approaches 1%.
(5) Addition of NaCl to alkali solutions showed an inhibit-
in effect on the processes of corrosion cracking.
(65 The relation between the time to failure and the absolute
test temperatiLre in corrosion cracking tests in alkaline
media show an exponential character. (7) Even if the heat
treatment does not show an appreciable influence on the
corrosion strengths of the steels lKhl8NqT and E125? inside
alkali media, it can prevent corrosion cracking since it re-
sults in the removal of internal stresses. There are 7 fig-

ASSTRAM The entrairmont of a plama cylinder in a uniform magnetic field by a ro-
tating electromagnetic J'Ield Is discussed In the magnetohydrodynamic approximation.,
The calculations were undertaken because rotation of a plasma cylinder can be useful
in prolonging its life, In suppressing flute instability, and possibly In beating it.
The rotating elect aglietic field discussed Is that due to currents proportional to
exp i(ft + m9) In the z direction on a cylindrical surface coaxial with the plasma cyl-
inder. Here r, 0, x.ars cylindrical coordinates, f is the frequency, and m Is an late-
ger. The nagnetohyifted.ynamic equations are solved by a sucoosal" approximation motbod-
based on expansion in pavers of the ratio of the strength of the alternating nagnstia
field to.*that of the uniform axial magnetic field. In the zeroth approximation the
plasma In assumed to be at root. The first approximation describes the distribution
of the high frequency fields In the plasmas but the plasms notion appears only In the

second approximation. lit order to obtain the second approximation It In assumed that
the entrainment time to long compared with the period of the high frequency field, and
all quantities are separs-ted Into slowly-varying and high-frequency parts. In the
second approximation these appear radial and azimuthal nations of the plama, a radial
electric field, and an aiinuthal current. ?be second approximation d*scr$bes only the
Initial stages of the plasma entrainment because the reaction of the plasms, motion an

eral form. The entrainuent time Is estimated under fuirther restrictive assumptions.

ABSTRACT: This Authorli) certificate introduces: 1. An aircraft passenger seat
~which is made up of a frame, a support, a chair with reclining back, headrest and
armr,est, a lock for fastening the support to guide rails, and a stop for locking
.the back. The seat is designed for use in airplanes with various bases for rail
imountings and for improved reliability in the fastening between support and rail.
Jhe supports have guides with index pins for moving them along a girder on the frame.':
The shaft of the lock which fastens the support to the guide rail has a f lattened
ihead on the lower end, and is equipped with a U-shaped clamp which goes awr the
'top of the rail. 2. A modification of this design-with provision for changing t e
