-ABSTRACT: The-information now 'accumulated on more-than 10i extragalactic super-'
novae have been obtained mainly through the international supernovae service
organized by,the American astrophysicist Fritz-Zwicky. which has lately been
discovering 10-20 a year. Because of the immense distances, they are rarely
than-the llth-12th stellar magnitude, which does not permit obtaining
brighter
a spectrum with high dispersion. In 1962., the young Tadzhik astronomer V.
Satvlvadi=, in-examining old plates, discovered that in September, 1956, a
ai
new star had flared up in Ursa Minor, but rem ned unnoted at that time by the
astronomerst magnitude 12.5 by 8 Oct.. 6.0 on 24 Sopt., down-to 3.1.5 a year
later. Now, the collection of star photos of the Gosudarstvenny*y Astronomiches-

50 to 130 fold, and that of the brightest elliptical galaxies ton-fold), and
they do not disappear in several weeks as do supornovae. Their radio emission
Soo-is to be caused by processes taking place in the rucloi of galaxies. Hoyle
and Fowlor (Mlonthly Notes of RAS, v.,,125 , No- 2, p. 169, 1963; ar#cle
writtlon in Aug. 1962) advanced the hypothesis of "hyporstars" in the nuclei of
gala:dos -- stellar typos with a masses up to 108 Solar masses -- as the source
o' the enorQr, resUting from the vast quantity of gravitational energy
liborated eduring the compression of a body of such mass. Optical astronomy
has supported t%o theory by providing estimates of the dimensions of ZS 273 and
ZS 48. ExcoodinCly important conclusions follow from the unexpected discovery
simultaneously in the USSR (Yofremov and Sharov) and USA (Smith and Koffleit,
of the variability of the brightness of ZS 273- Soo light curve, presented in
Fig. I of the Enclosure. The American study, based on more material, found a
cycle of z:bout 10 years and, at the same time, less significant fluctuations
lasting about a week- from this information, density of the object was estimated
to be 10-10 g/CM3 (Smith and Hoffleit), and its d:Jinensions to be not significant-
ly in excess of a light week (Ouk). Another riddle presented by the hyperstars
is how the energy, accumulated in the nuclei of galaxies during compression,

is liboratod. This should be an intensive oxplosion-liko process, but not a
nuclear process, as Hoyle and Fowler initially assumed. The neutrino hypothesis
of F. 1-:isholl (USA) has been demonstrated by Academician Ya. B. Zel'dovich to
be hardly possible owing to the effects of the genoral theory of relativity
which have to be taken into account. Whoroas tho five radio stars now known
are apparently early stages of development of great radio galaxies, a later stage,
in the evolution of such objects may be exemplified in phenomena rocontly obsorv-
Gd in an unusual iadio galaxy M 82 by Mnds ahd'Sandage (USA), interpreted by
them as the first identified case of an hyper-powerful. explosion in the central
region of a galaxy: this explosion created relativistic electrons which explain
the radio emissions and, in part, the optical 0'rralssion of the system. 1. S.
sto s ctra that ot all
Shklovskiy has recently concluded from study o. llar pe
objects in the UrAverse ZS 196 is the most remote from us %4 x 109 parsecs), and
ZS 286 the next most distant. The discovery of hyporstars is ccmpardole in
importance to such a fundamental discovery as the detection of the rod shift in
galactic spectra, and presages a now stage in the development of co=ology.

W10, containing various amounts of 0-phase. Alloy_1VT1416ntained 4.45% 91-,2.7% Mo

6.*3% Mo. Samples (8 x 20 x 20 am) were heated in air at temperatures ranging from 70011
to 11001C for 10 to 2110 min. Oxidizability war determined by the increase in weight
per unit surface. The weight curves followed a parabolic law. While the oxidation
rate was low for all alloys up to 9000C, above 10000C it became intense. In compari- id

VT16.i-Electron diffraction was used to analyze the scales. Chemical compositions of
the at 11000C for 4 hrs are given. In all alloys, the basic oxide com-~
position was rutile-type titanium dioxide, having a tetragonal lattice with the Para ,-
meters a=4.58 A and c=2.95 A. All the oxides had a texture in which the Cool] direc'
tion lay in the plane of thy sample. A texture formed at 7000C in VT15, at 8000C i~"
VT14 and at 9000C in VT16. LMicrohardnesses of the surface layers are given as func-
tions of distance from the surface for all temperatures. Micrographs of the oxidized
surfaces are shown. For all alloys, the microhardness dropped sharply up to about
0.02 rrun from the surface where the slope became more gradual; this indicated the depth
of gas diffusion at the surface. The single phased alloy VT15 had a large-grained
structure and the gas diffusion was more selective, as was similarly observed in the
other alloys upon heating in the O-region This selective attack increased the crack
sensitivity and a fine network of crackstwas observed upon deforming VT15 at high tem-
peratures. Below 9000C, YT14 and VT16 had two-phased a+$ structures and the oxida-
tion attack was more uniform . Orig. art. has: 3 figures, 2 tables.

ABSTRACT: f4easurements of plane-persllel terminal gages 1,000 mm long
nre made on the interforomoter developed by VNITV by mennn
of comparing them with a special calibrating device! (Ref. 1).
The accuracy of the measurements depends on how.well the
length of the calibrating device is known during comparison.
The calibrating devices consist of steel tubes and are photo-
graphed during measurements. A simpler method has been pro-
posed by Baird (Ref. 2). The calibrating device is put in a
chamber in which the pressure is changed by a pump. The
brilliance of a diaphragm changes with the pressure in the
chamber and indicates changes in the interference. The
visual method of observation has been replaced here by the
photo-electric method of recording. A diagram of the device
is shown in Figure 1. The light is emitted by the lamp (1)
with the isotope Cdll4. As a recording device (15' the auto-

Application of Photoelectric Pecording of Interference Bonds
on the tube 6F5 is used. For the measurements of terminal
gages it is sufficient to determine the interference with an
error of only 0.01. Photoelectric recording moves the maxi-
mum always in the direction of higher interference. The ob-
served values of interference are therefore always smaller
than the real values. The photoelectric method of recording
is objective, reliable and fast.

ABSTRACT: The utilization of lines of the infrared part of the
spectrum along with lines of the visible part of the
spectrum is made possible with the use of pho-roelec-
tric registration of interference fringes for the mea-
surement of standards with a Fabry and Perault inter-
ferometer. Experimental measurements of the semiwidth
of certain lines in the near infrared part of the
Kr 86 spectrum were made for possible utilization of
these lines for the interferential measuring of the
length. As a source of light, a lamp of the Kaesters
and Engelgard type with Kr 86 was used, energized at

sion the author finds that the lines of the near in-

ferential measuring of length, especially when the pro-
pagation difference exceeds 500 mm, in case measure-
ments with lines of the visible part of spectrum are

PERIODICAL: Optika I spektroskopiya, 1960, Vol 8, Nr 2,

ABSTRACT: All photoelectric devices used to record interference rings
of equal inclination have a diaphragm which separates out
the central portion of the patterns. Light passed by this
diaphragm reaches a photoelectric receiver connected to an
amplifier and an automatic recorder. When separations of
Fabry-Perot plates are not too small, a change in the
order of interference is produced most simply by a change
in the pressure of air between etalon mirrors (Refs 1-3).
The automatic vecordez- records a series of consecutive
interf.,erence orders. Maxima do not, however, occur at
integral values of the interference order N but at some-
what larger values N + 6c (the interference bands seem
to be displaced towards higher orders). Chabbal (Ref 4)

X is the wavelength and f is the focal length of the
objective. Rank et al (Refs 6, 7) showed that for a
narrow slit be = 0.325A . Rank et al found also that
for a square diaphragm Oe = 0.5A, where Al represents
the value for a circular aperture whose diameter is that
of a circle inscribed on a square.. The present paper
reports results of calculation of be for rectangular
diaphragms (sides a and b) . The results obtained
differ from those of Rank et al. For example, if
a = b , i.e. for a square diaphragm -be = 0.64A, = 0.32,&
where A Is defined as A = t Va 2 _~ b2/4X f2 . The
authors determined also experimentally the values of
6C/A for various values of a/b . The technique used
Card2/.3 was described earlier (Refs 8,9). The yellow-green lines

Fabry-Perot etalons were of 47 and 100 mm length.
Experimental results are shown in a figure on p 268 in the
form of a dependence of be/A on n/b . For a square
diaphragm the experimental value was bc = 0-32A in
good agreement with the calculated value. For rectangular
diaphragms with a/b = 0.5 , be/A = 0.22 . Extrapolation
of the graph to a narrow slit (a/b)-->O yielded a
value be/A =-0.16 . The latter two values lie withi.n

TOPIC TAGS; gaseous Btate laspr, laser application, interference measurement
ABSTRACT: The results are reported of an application of a Soviet-made OKG-11 He-Ne
laser to the interference measurement of precision gage blocks up to I m long. The
contour of the Ne-line ( X.- 0.6328 v ) and the stabilization and reproduction of
this line are discussed. Measured on a conventional (Hg198) interferometer, the
average wavelength was X = 0.63281968 u in the normal air (20C, 101325 n/m~j
1333 n/M2 H20; O-OY0 C02); the mean square error was 1 5 x 10"a v . It is believed
that the He-Ne lasers can be efficiently used for interference measurements of
large units of length; the wavelength of each laser must be tested by comparing
it either to a Kr86-radiation wavelength or to Kr86, Hegs, Cd114 secondary-radiation
standards. Orig. art.has: 3 figures and I table. [031

Abstract A study-of the reaction kinetics during the oxidation of potassium axalate
with potassium permanganate at different temperatures showed that the reaction
process is not perfectly and not accurately represented by the N.A. Shilov
equations. The curves were found comparatively satisfactory up to the point
of maximum rate of reaction after which they become inaccurate. The curves
obtained at relatively low temperatures are more accurate than the curves
obtained at a higher temperature, Three USS? referen*ies (1905-1952)'. Graphs.

TEXT: In conjunction with the production of high-purity(4-amino-
henr~pcanoic acid for the synthetic fiber manufacture, its solubility was
investigated in water-alcohol mixtures at 20 - 1000C. The crystallized
acid was heated in a sealed ampoule with the alcohol dissolved in water
until complete dissolution occurred. Results: (1) The solubility of
63-aminohendecanoic acid passes a maximum at 46~-, by weight of ethanol.
(2) The solubility increases rapidly at higher temperatures and reaches
30;,', by %-,eight at 1000C (in 46~4 by weight of ethanol). There are 2 fig-

ABSTRACT.- This investigation is an extension of work on haterochain copolymars,
previously published by B. A.,Rozenberg, Ye. Bo Lyudvigj A. R. Gantmakbor, and S. S.
MedvedGv (Vysokomolek. soyed, 7. 188, 1965). It was shown that random, block,, and
graft polymers may be synthesized using a chain transfer mechanism in which a. chain
transfer occurs from a heterochain copolymer to the growing polymer. Experiments
were carried out on the following pairs or polymers: polydioxolane - polyolg7wthylene
(random or block copolymer)* polytetrawthylonoxide - polyoVmethylene (gral,'t
copolymer); polyvinylbutyl eater - polyo7qwthylene (random or block copolym4w);

ABSTRACT Ursa forms crystalline complexes with nearly all types of organic
compounds that ha-re a straight chain: hydrocarbons, ethers,
aldehydes, acids, alcohols, eto. The opinion prevails that at
temDeratures of more than 132,70, i.e. at the melting point of
urea, these complexes cannot exist. Although no such complexes
have hitherto been discovered, it is neyertheless unexplainable
from a thermodynamic point of view why 132-70 should be the
upper limit for the existence of such a complex, Thermal con-
stancy increases with thf lenoth of the chain of organic ,.om-
pounds, The thermal constancy of a complex obtained from a
mixture of organic snbstanoes is higher than that which is due
to individual compounds forming a mixture. On their search for 0
complexes that are constant at temperatures of' more than 132,7

the authors therefore carried out experiments with paraffin and
ccT-in., i.e. with multicomponet mixtures consisting on the
whole of long-chain hydrocarbons of the paraffin series,, They
were synthetized with urea in a sealed glass tube. The urea
complexes with ceresin of different types are constant at
Llemperatures that are higher than the melting point of urea
(up to 1410 in the case of ceresin Nr- 3), This constan-.y could
also be checked by studying the equilibrium between the
complex and urea in unsaturated solutions of the latter, In
aqueous solutions the thermal stability of the complex is
dependent on the concentration of urea in the solutions, In
order to be able to judge the constancy of the complex at
temperatures of more than 132,70 it would be necessary to
follow the course of the temperature curye. As a solvent liquid
ammonia was used, as water is not suited for the purpose. The
complex was synthe-bized in a manner similar to that described

complex with cetane was investigated, where urea probably
partly decays, and where the curve of solubility intersects
the constancy curve of the complex at 990. Besides, some
qualitative observations concerning the forming of the complex
were made, Thus ut was shown by the examples of urea complexes
with ceresin that the nelting point of urea (132,7o) by no
means forma a limit for the existence of this complex, but

ABSTRACT: An interesting case of phase equilibrium (PE) in binary
systems is the one where the critical curve and the solubility
curve intersect (Ref 1). In both intersecting points P and Q,
critical phenomena can be observed in saturated solutions in the
presence of the solid phase B (solid) (Fig 1). The described (PE)
occurs if the melting point of one component B lies considerably
above the critical temperature (CT) of the other component A,
and the solubility B (solid) in A (liqu) is lov and decreases
with the temperature. In such systems, there are two areas of
pressure and temperature in whIch the three-ptiase equilibrium
(TPE) of solid body - liquid - gas can ba obsorved. Betwoen
these two areae, there is the area of two-phass equilibrium
(TPEI) of solid body - gas. The nbove-mentioned equilibrium

above the ~CT of (1), was studied by the last.-mentioned
in7estigation method (Fig 2 sholve the dev_'~,e used). The (TPEI)
of solid (II) - gaseous solution was examined on a device
designed by D. S. Tsiklis (Pig 4); the soiubility and density
of the solid (II) in gaseous (I) was measured at temperatures
of 15C-500' 0 and a pressure of 20C-500 atmospheres. At the
(CT) of the solution of soled (II) in liquid (1) (1340 C),
critical phenomena could be observed in the presence of solid
(H). The second critical point of the equilibri-am liquid -

TEXTz The authors studied the phase equilibria, critical phenomena, and
volume behaviors of liquid and gaseous solutions in the system ethylene
butarie. They give the composition of bottled butane and ethylene, and
describe their purification. The purity of ethylene and butane was
determined on the basis of constant vapor pressures by an apparatus
described earlier (Ref. 2)~ Fig~ 1 shows the p = f(y) curves for an
experiment in the system ethylene - butane. The authorn measured the
solubility of ethylene in liquid butane and the volumes of saturated
liquid solutions at temperatures between 0 and 750C, The solubility of
liquid butane in gaseous ethylene was measured by the polythermic method
(Ref. 10); for this purpose, data were needed on the relation volume -
temperature - composition and on the relation pressure - temperature -
composition,, Fig. 2 shows the curve v - f(t) for ethylene butane

pressibility of ethylene -- butane mixtures was determined by an apparatus
which is schematically shown in Fig, 6. The compressibility of four
ethylene - butane mixtures of different compositions was measured by the
method described. The authors determined the volume - composition
isotherms.-Isobars in the ethylene- butane system- Table 4 gives the
results of calculation of the volatility of butane in solution at the

TITLE:. Solubility of Melamine in Solutions of Dicyano Diamide in
Liquid Ammonia
PERIODICA:L: Khimicheskaya promyshlennostf, 1960, No. 8, pp. B-9
TEXT: The solubility of melamine in ammoniacal solutions of dicyano di-
amide, being of-particular importance in the first stage of continuous
melamine production from dicyano diamide (Ref. 1), was studied in sealed
glass ampoules by the method described in Ref. 2. The data obtained
(Figs. I and 2) show the solubility of melamine to be dependent upon the
concentration of dicyano diamide in liquid ammonia. For a dicyano diamide
content of 9.2 g11OO g ammonia the solubility of melamine ia little
dependent on temperature; on a further increase of the dicyano diamide
concentration in the solution a change is observed in the character of the
solubility curve; with a rise of temperature also the melamine concentiation
in the solution rises. Fig. 2 shows that for dicyano diamide concentrations
of about 14 g1loo g rH3 the solubility of melamine is independent of

the continuous process tho If4C2N4 concentration in liquid ammonia :is 50;,G'
and the temperature of the solvent is -700C, the melamine content in such
a solution should not exceed 4%- It also follows from results that the
sign of the solution heat changes with a rise of dicyano diamide con-
centration in the solution. There are 2 figi.ireo and 3 Soviet refereneco.
