ABSTRACT: The principles of radiation polymerization of unsaturated organophosphorufi-
compounds were investigated in this sti0y with molten diphenylvinylphosphine oxide.
Products with relatively high molecular weights (higher than in chemical
polymorization),were obtained. Kinetics study showed the monomer was completely
converted to polymer& There was no induction period and the polymerization rate
increased constantly up to 60-70% conversion. 'ibere was no gel effect as is usual in
radiation polymerization* Folymerization rate vas directly proportional to radiation
dosage, so radiation yield and noleou3sr weight'were independent of dosage* Energy

inhibitors,and initiators confirmed the radical mechanism of polymerization* X ray
study showed'the monoorystalline structure was tetained up to about 20% polymerization~
An'the solid phasel bY 50-60% conversion-the'polymer had no characteristic crystalline'

TITLE:- Regulating computer for ferroalloy are furnaces
PERIODICAL: Byulleten' tekhniko-ekonomicheakoy informa~sii, no. 2, ig6o, 8-io
TEXT: The author describes the design and function of a regulating computer
for ferroally arc furnaces, developed by the Thiliskiy nauchno-issledavate'A. Iskiy
institut priborostroyenlya I sredetv avtomatizaisii (Tbilisi Scientific Research
Institute of Instrument Making dnd Automation-Equipment) (TNIISA). This computer
is intended to control the accuracy of regulators which are to maintain the
definite ratio of current to voltage In high-power electric arcs. 7be computer
A.
performs operations of algebraic addition, multiplication and integration . T*
is composed of building blocks designed for electronic enalog computers. The
utilization of the computer required the introduction cof a measuring cur-.ent.
transformer I and excitation choke,2 into the circuit of' the extsting regulator.
The latter replaced the butotransformer. For the Input of alternating values
into the computer, which are proportional to the voltaj;e of the are - fusion
zone measuring voltage transformer 3 is provided. This transformer receives the

Regulating computer for ferroalloy arc furnaces Aco4/Aool
voltage acting between the tracer and the electric zero point of the furnace.
A steel wire 2-4 mm in diameter is placed in the furnace lining to lead out the
electric zero phase. The.voltage, proportional to the current phase of the
fLrnace being regulated and to the-voltage of the arc - fusion zone, is fed into
multiplying block 4. The voltage at the output of the multiplying bl*ak Is
Proportional to the power or, at a corresponding switching over, to the square
of the current of the furnace phase being regulated. This voltage is supplied
to summing integrator 5. The unbalance voltap, fondng as a result of summing
up, is integrated and acts on control winding 6 of choke 2, thus effecting the
integrated correction of the regulator current circuit. Excitation winding 7
of the same choke is intended for the current control in tae regulator current
circuit. The service tests showed that regulator 8 equipped with a computer
increases by 1-2% the accuracy of maintaining the mean current value in the phases
and the mean power value in the are - fusion zone. The au"'hor points out that
TNIISA has developed a computer for the continuous measurement of the real and
reao4janoe resistance in the short oircuit. There is 1 figure.

ABSTRACTs Silver - carbon foils may be used for studying electron-
microscopically the fine structure of nickel alloys. Silver
is dusted onto the pickled ground section in a vacuum
(jo-4 mm 11g). The thickness of the silver layer is a few
microns, and it can be easily detached. Carbon is then dusted
onto this negative silver"print" of the ground section.
This is, againg done J_n the vacuum. This dual-layer silver-
carbon foil is then placed into nitric acid, where the
silver dissol&~_&nd the carbon foil floats up. The latter
is then cleaned and studied -electron-microsccpi::a11-,;. The
electron.microphotograph of a ZhSZ alloy is given kFig).

ABSTRACT: Some parameters of fluxes for magnetic storms following anomalous
absorption in the polar cap (AAPC) were investigated on the basis of data obtained
at the Dusheti Magnetic Observatory and the ionospheric data for the IGY. These
parani-efiis'-air-e*-c- -o-m~-p.-a-r-e-d'-.w-.it--h-.t.h--e parameters of usual fluxes. Also, AAPC
dynamism in the period of the development of a geomagnetic storm was studied.
On the basis of the condition that the energy density of the corpuscular flux at the
boundary of the magnetosphere and that of the geomagnetic. field are equal, the
authors derive a formula connecting the magnetospheric. radius R with the increase

of the geomagnetic field and on the equator into the initial stage of storm
R and flux densities n are calculated for various storms. It is concluded that
in comparison with ordinary storms, the storms correlated with AAPC have a
larger R and a lower n. It is stated that denser fluxes possess more intensive
magnetic fields. It is noted that there is a divergence between theoretical and
experimental values of the geomagnetic latitude of the external zone of anomalous
absorption. This divergence is esp-ecially noticeable at the moment of the highest
geomagnetic field depression. L Kovalevskiy, '[Translation of abstract]

ABSTRACT: The chamber was constructed in 1954 for the Academy of
Sciences of the Georgian SSR and the Tbilisi State University.
The object was to observe hyperons and heavy mesons produced in
absorbers placed both directly above the chamber as well as
inside it. The chamber works in a magnetic field of 4 500 Oe.
It consists of two independent chambers with a dividing
chamber between the working volumes. The working volumes and
the chamber between them are in an all-metal three-sectional
body while the expansion device isplaced in a two-section massive
base. Such a system is convenient for the following reasons:
1) the walls of the middle chamber act as the thermal areen
because they are part of the massive body of the chamber and
have good thermal conductivity. Absorbers placed in this
(;ardl/3 chamber do not affect the thermal regime and do not lead to an

additional distortion of track curvature which is often
observed when absorbers are put directly into the chamber
(Ref.1); 2) Counters can be placed (if necessary) in the
middle chamberi 3) The use of separate chambers placed one
above the other (Ref.2) is not always convenient. Constru-
ctional details of the chamber are shown in Fig.l. The soft,
iron body is divided into three sections by means of partitions
made of brass and 6 mm thick. The two extreme sections form
the working volumes of the c4amber with an illuminated
volume of 280 x 106 x 100 mm;" each. In the dividing com-
partment formed by the middle section one can place various
absorbers. Suitable glass windows are placed in the walls
of the chamber. All the internal parts were nickel-plated.
In order to remove distortions due to convection currents, the
chamber is specially thermostatted to about 1/100th of a
degree Centigrade. The working cycle of the chamber is fully
automatic. Control measurements have shown that the curvature
of A meson tracks is in agreement with the calculations in
Ref.4. The following persons collaborated: B.L. Andronikash-

ABSTRACT: This paper arialyzes 10 decays of heavy chargea particles. These
particles were observed by means of a device which is similar
to the device of C,11,. Jork et al.(Ref 2), Investigations
were! carried out in the Vysoko,-ornaya El'brusskaya kosmiches-
kaya laboratoriya, (Ellbrus High Mountain Cosmic Laboratory).
For the measurements discussed in this paper a rentangular
double cloud chamber was used. This cloud chamber consists
of two.independent volumes (each of them has the dimensions
28O;r-1OOx11O mm) and three sections for the absorber. The two
independent volumes are united by the same carcass. The cloud
shamber was filled with argon (1000 torr) and a mixture of
70 'i~a ethyl alcohol and 30 ~ water was used asoondensate. The

over, 10 forked tracks were bserved on these photographs,
they inay be interpreted as V4decays. The authors found also
22 V~-decays. I decay of a c+--meson, 1 decay of Lions (while
9p
they ivere moving), and 13 stars. The results of the measure-
ments of the momenta, angles and the approximate values of
the ionization are compiled in a table. All the observed de-
cays, (with the exception of one), taking- account of the
observation errors, lie within the allowed ranj,-e for hyperons
and K-mesons,. Only one case can be exactly interpreted as the
decay of a K.-meson, for all. the other cases it is impossible
to discern between K - and iY - decays. Among the decay products
no proton was found. The V -decays, are divided into two groups,
according to the character of production. The 6 partlcl~*s of
the first group have a very low ionization caused by the pri-
mary particles. The second group consists of 4 slow particles

the place of the decay. One decay is interpreted as the decay
of a particle which is heavier than a K-meson. It is possible
to assume that this particle is the charged analogon of the
neutral meson the decay of which was observed by Kovan (Ref 12).

. The production of heavy non-stable particles was studied in a magnezic
field cloud chamber controlled by penetrating showers. 139 V!, and 34 V i - particles
were observed.
On the basis of the obtained data, the existence of "forward-backward" asymmetry
of disinte rg ration products is considered. The lifetimes forA'-Und2l-hyperons are
determined. The value obtained forUtagrees with the preliminary estimation given
in JETP V. 34, 1,110, 1958 and does not contradict the results obtained with
acceler'ators (Proceedinp of the 8th Rochester Conference).
The value for the A6particle lifetime, determined for all the cases observed
agrees with known cosmic data and is therefore larger than the timete obtained with
accelerators. At the time, for those cases which correlate with the visible point
of shower generation, the value obtained forteproves to be closer to the value
obtained with accelerators. An explanation is given for the difference existing
between the value of theA~particle lifetime determined by cosmic data and that
obtained with acceleratore.

TEXT: If, in strong interactions with the participation of strange partic-
les, parity is not conserved, this may manifest itself in the presence of "for-
ward-backward" asymmetry in 9-hyperon decay with respect To the line of flight
of hyperons in the center-of-mass system of their generation. The literature
contains indications as to the presence of the effect of asymmetry in the decay
of JSP generated on compound nuclei and in hydrogen by pions with a momentum of
some Bev/c and by particles of cosmic radiation. On the other ha:ld, no longi-
tudinal polarization of 9-hyperons has been established in a number of studies
conducted on hydrogen at low and mean energies. In the present experiment,
conducted with the aid of a doubled Wilson chamber at 1,800 m above sea level,

as much as 162 Vo-decays were found. The chamber was controlled by penetrating
showers. From among lead-generated V'Ldecays, as much as 54 Ao-hyperons were
identified. Of these, 24 V-decays witli a momentum 4~800 Mev/c were picked olat.
In these decays, the coefficient of asymmetry was found to be equal to -0-59�0.28
in good agreement with -0.56�0.15 and -0.58�0.17 of earlier findings.

ABSTRACT: The principles of radiation polymerization of unsaturated organophosphorufi-
compounds were investigated in this sti0y with molten diphenylvinylphosphine oxide.
Products with relatively high molecular weights (higher than in chemical
polymorization),were obtained. Kinetics study showed the monomer was completely
converted to polymer& There was no induction period and the polymerization rate
increased constantly up to 60-70% conversion. 'ibere was no gel effect as is usual in
radiation polymerization* Folymerization rate vas directly proportional to radiation
dosage, so radiation yield and noleou3sr weight'were independent of dosage* Energy

TITLE:- Regulating computer for ferroalloy are furnaces
PERIODICAL: Byulleten' tekhniko-ekonomicheakoy informa~sii, no. 2, ig6o, 8-io
TEXT: The author describes the design and function of a regulating computer
for ferroally arc furnaces, developed by the Thiliskiy nauchno-issledavate'A. Iskiy
institut priborostroyenlya I sredetv avtomatizaisii (Tbilisi Scientific Research
Institute of Instrument Making dnd Automation-Equipment) (TNIISA). This computer
is intended to control the accuracy of regulators which are to maintain the
definite ratio of current to voltage In high-power electric arcs. 7be computer
A.
performs operations of algebraic addition, multiplication and integration . T*
is composed of building blocks designed for electronic enalog computers. The
utilization of the computer required the introduction cof a measuring cur-.ent.
transformer I and excitation choke,2 into the circuit of' the extsting regulator.
The latter replaced the butotransformer. For the Input of alternating values
into the computer, which are proportional to the voltaj;e of the are - fusion
zone measuring voltage transformer 3 is provided. This transformer receives the

voltage acting between the tracer and the electric zero point of the furnace.
A steel wire 2-4 mm in diameter is placed in the furnace lining to lead out the
electric zero phase. The.voltage, proportional to the current phase of the
fLrnace being regulated and to the-voltage of the arc - fusion zone, is fed into
multiplying block 4. The voltage at the output of the multiplying bl*ak Is
Proportional to the power or, at a corresponding switching over, to the square
of the current of the furnace phase being regulated. This voltage is supplied
to summing integrator 5. The unbalance voltap, fondng as a result of summing
up, is integrated and acts on control winding 6 of choke 2, thus effecting the
integrated correction of the regulator current circuit. Excitation winding 7
of the same choke is intended for the current control in tae regulator current
circuit. The service tests showed that regulator 8 equipped with a computer
increases by 1-2% the accuracy of maintaining the mean current value in the phases
and the mean power value in the are - fusion zone. The au"'hor points out that
TNIISA has developed a computer for the continuous measurement of the real and
reao4janoe resistance in the short oircuit. There is 1 figure.

ABSTRACTs Silver - carbon foils may be used for studying electron-
microscopically the fine structure of nickel alloys. Silver
is dusted onto the pickled ground section in a vacuum
(jo-4 mm 11g). The thickness of the silver layer is a few
microns, and it can be easily detached. Carbon is then dusted
onto this negative silver"print" of the ground section.
This is, againg done J_n the vacuum. This dual-layer silver-
carbon foil is then placed into nitric acid, where the
silver dissol&~_&nd the carbon foil floats up. The latter
is then cleaned and studied -electron-microsccpi::a11-,;. The

ABSTRACT: Some parameters of fluxes for magnetic storms following anomalous
absorption in the polar cap (AAPC) were investigated on the basis of data obtained
at the Dusheti Magnetic Observatory and the ionospheric data for the IGY. These
parani-efiis'-air-e*-c- -o-m~-p.-a-r-e-d'-.w-.it--h-.t.h--e parameters of usual fluxes. Also, AAPC
dynamism in the period of the development of a geomagnetic storm was studied.
On the basis of the condition that the energy density of the corpuscular flux at the
boundary of the magnetosphere and that of the geomagnetic. field are equal, the
authors derive a formula connecting the magnetospheric. radius R with the increase

of the geomagnetic field and on the equator into the initial stage of storm
R and flux densities n are calculated for various storms. It is concluded that
in comparison with ordinary storms, the storms correlated with AAPC have a
larger R and a lower n. It is stated that denser fluxes possess more intensive
magnetic fields. It is noted that there is a divergence between theoretical and
experimental values of the geomagnetic latitude of the external zone of anomalous
absorption. This divergence is esp-ecially noticeable at the moment of the highest
geomagnetic field depression. L Kovalevskiy, '[Translation of abstract]

ABSTRACT: The chamber was constructed in 1954 for the Academy of
Sciences of the Georgian SSR and the Tbilisi State University.
The object was to observe hyperons and heavy mesons produced in
absorbers placed both directly above the chamber as well as
inside it. The chamber works in a magnetic field of 4 500 Oe.
It consists of two independent chambers with a dividing
chamber between the working volumes. The working volumes and
the chamber between them are in an all-metal three-sectional
body while the expansion device isplaced in a two-section massive
base. Such a system is convenient for the following reasons:
1) the walls of the middle chamber act as the thermal areen
because they are part of the massive body of the chamber and
have good thermal conductivity. Absorbers placed in this
(;ardl/3 chamber do not affect the thermal regime and do not lead to an

additional distortion of track curvature which is often
observed when absorbers are put directly into the chamber
(Ref.1); 2) Counters can be placed (if necessary) in the
middle chamberi 3) The use of separate chambers placed one
above the other (Ref.2) is not always convenient. Constru-
ctional details of the chamber are shown in Fig.l. The soft,
iron body is divided into three sections by means of partitions
made of brass and 6 mm thick. The two extreme sections form
the working volumes of the c4amber with an illuminated
volume of 280 x 106 x 100 mm;" each. In the dividing com-
partment formed by the middle section one can place various
absorbers. Suitable glass windows are placed in the walls
of the chamber. All the internal parts were nickel-plated.
In order to remove distortions due to convection currents, the
chamber is specially thermostatted to about 1/100th of a
degree Centigrade. The working cycle of the chamber is fully
automatic. Control measurements have shown that the curvature
of A meson tracks is in agreement with the calculations in
Ref.4. The following persons collaborated: B.L. Andronikash-

ABSTRACT: This paper arialyzes 10 decays of heavy chargea particles. These
particles were observed by means of a device which is similar
to the device of C,11,. Jork et al.(Ref 2), Investigations
were! carried out in the Vysoko,-ornaya El'brusskaya kosmiches-
kaya laboratoriya, (Ellbrus High Mountain Cosmic Laboratory).
For the measurements discussed in this paper a rentangular
double cloud chamber was used. This cloud chamber consists
of two.independent volumes (each of them has the dimensions
28O;r-1OOx11O mm) and three sections for the absorber. The two
independent volumes are united by the same carcass. The cloud
shamber was filled with argon (1000 torr) and a mixture of
70 'i~a ethyl alcohol and 30 ~ water was used asoondensate. The

they inay be interpreted as V4decays. The authors found also
22 V~-decays. I decay of a c+--meson, 1 decay of Lions (while

they ivere moving), and 13 stars. The results of the measure-
ments of the momenta, angles and the approximate values of
the ionization are compiled in a table. All the observed de-
cays, (with the exception of one), taking- account of the
observation errors, lie within the allowed ranj,-e for hyperons
and K-mesons,. Only one case can be exactly interpreted as the
decay of a K.-meson, for all. the other cases it is impossible
to discern between K - and iY - decays. Among the decay products
no proton was found. The V -decays, are divided into two groups,
according to the character of production. The 6 partlcl~*s of
the first group have a very low ionization caused by the pri-
mary particles. The second group consists of 4 slow particles

neated with a visible interaction and are generated far from
the place of the decay. One decay is interpreted as the decay
of a particle which is heavier than a K-meson. It is possible
to assume that this particle is the charged analogon of the
neutral meson the decay of which was observed by Kovan (Ref 12).

. The production of heavy non-stable particles was studied in a magnezic
field cloud chamber controlled by penetrating showers. 139 V!, and 34 V i - particles
were observed.
On the basis of the obtained data, the existence of "forward-backward" asymmetry
of disinte rg ration products is considered. The lifetimes forA'-Und2l-hyperons are
determined. The value obtained forUtagrees with the preliminary estimation given
in JETP V. 34, 1,110, 1958 and does not contradict the results obtained with
acceler'ators (Proceedinp of the 8th Rochester Conference).
The value for the A6particle lifetime, determined for all the cases observed
agrees with known cosmic data and is therefore larger than the timete obtained with
accelerators. At the time, for those cases which correlate with the visible point
of shower generation, the value obtained forteproves to be closer to the value
obtained with accelerators. An explanation is given for the difference existing
between the value of theA~particle lifetime determined by cosmic data and that
obtained with acceleratore.

TEXT: If, in strong interactions with the participation of strange partic-
les, parity is not conserved, this may manifest itself in the presence of "for-
ward-backward" asymmetry in 9-hyperon decay with respect To the line of flight
of hyperons in the center-of-mass system of their generation. The literature
contains indications as to the presence of the effect of asymmetry in the decay
of JSP generated on compound nuclei and in hydrogen by pions with a momentum of
some Bev/c and by particles of cosmic radiation. On the other ha:ld, no longi-
tudinal polarization of 9-hyperons has been established in a number of studies
conducted on hydrogen at low and mean energies. In the present experiment,
conducted with the aid of a doubled Wilson chamber at 1,800 m above sea level,

as much as 162 Vo-decays were found. The chamber was controlled by penetrating
showers. From among lead-generated V'Ldecays, as much as 54 Ao-hyperons were
identified. Of these, 24 V-decays witli a momentum 4~800 Mev/c were picked olat.
In these decays, the coefficient of asymmetry was found to be equal to -0-59�0.28
in good agreement with -0.56�0.15 and -0.58�0.17 of earlier findings.
