ABSTRACT: Studies in improving the 16 ChN 24/27 diesel locomotive engine with high
gas-turbine.supercharging from a self-contained compressor are discussed. The experi-
mental part of the work was done with a one-cylinder section of the engine. It was
found that cooling of the supercharger air makes it possible to increase -the maximun
possible power of the engine and to improve its economy under all operating conditions

ABSTRACT: The circuit comprises a 6-winding transformer and 18 single-anode
valves. Secondary phase -to -neutral voltage vectors are 400 apart. The valves
are connected in 3 three-phase bridge circuits, the bridges being connected in
series. Such a circuit has the following advantages: good utilization of the
transformer, a high ratio of the rectified -to -secondary phase -to -neutral
voltage (equal to 7. 02), a relatively low back voltage, small rectif ied voltage
ripple, absence in the primary current of harmonics below the 17th. The
circuit was analyzed with an allowance for the inductance of anode chokes

TITLE, Some Peculiariti~es of the Thermal Stimulation of the Conduc-

PERIODICALi Fizika tverdogo tela, 1960, Vol. 29 No. 6, PP. 1141 - 1147
TEXT. The aTticle under review deals with the following problems of the
above-mentioned subjectt recoinbination and filling up of electron traps
as the maximum of thermally stimulated conductivity (TSC), the part played
by the surface in this connectiong and the possible relationship between
the photoconductivity of CdS single crystals and the area of the TSC curve.
TSC was measured by means of an apparatus described in the paper of Ref. 7.
The 3pecimens were exposed to whtte light, the wave-lengths N,>0.8 it being
excluded. Beside samples with a pure stoichiometrical ratio of the compon-
en,.s, t'he authors studi-ed such with an excess of one component. The measure-
men-"- citained were in full agreement with those already described in Ref.7.
At a Cd excess, peaks were observed in the range of -1,95 tc, -180 0C, and at
r6 V~

only a slight Cd excess, also a peak in the ranke- of 15 - 25 C, at an 3
excess a number of peaks, the highest peak at 0 - 6 OC. From the results
obtained here and from further investigations on the temperature dependence
of the adhesion cross section of the excess component a(T) the attempt was
made to determine the depth of the levels caused by the excess. Experiments
,.,.,ere made at higher temperatures on CdS(Au) and CdS(S) crystals whith were
kept at low temperatures and were then hardened. In these crystals, the
plane bounded by the TSC curve is completely independent of temperature.
Such a dependence was, however. established on the CdS(S) single crystal
(Fig. 1). A maximum filling of the traps with electrons at the various il-
lumination conditions takes place at -.65 to -50 00. 0(T) drops exponentially
with all crystals, which fact is ascribed to the necessity of surmounting a
potential threshold in these crystals. At high temperatures as well it is
possible to observe a decrease in the filling of the local levels, but no
explanation could be provided for this. Experiments made on the determin-
ation of the filling degree at temperatures of the TSC maximum (T) (Fig. 3)
showed the recombination taking place to be predominantly monomolecular.

-evealed a decrease in the.maxima with strong light absorption. This was
best observed on CdS(S). A special treatmen'. of the surface (short etchinEE
wl"L HCl) did not appreciably change the TSC peaks ncr photosensitivity,
,
.nd now maxima did not arise
a . This shows that the impurities on the crys-
tals did not form any surface film, but that they penetrate into the crys-
tals. The influence of mica discharge manifested itself by a considerable
enlargement of the areas of the TSC curvesi a strcngincreasu- ir, light sen-
sitivity and by the app-earance of a strongly retarded quasi-.dark conduc-
tance (Fig. 4 , the peak becomes very much larger).The determination of
the level depth is rendered more difficult in this connection. The study of
* dependence between TSC curve areas and photosensitivity revealed (data in
* table) that samples undergoing the same treatment exh;bit the same rela-
tion between the quantities mentioned. A rigorous correlation between the
~wo quantit_,es can be set up only under consideration of the lifetime of
electrons in the conduction band. Still, it was possible to establ4sh a
L,z~z,-Zaixi dependence of the photosensitivity on the concentration of the loc-,
al 'evels in the outer part of the forbidden zone. The authors finally

where a is the propagation rate of the waves of a flexure of length X. on the basis
of this formula the authors present several practical examples of the derivation of
final engineering formulas for the propagation rates of flexural waves. These
examples pertain to: natural oscillations of a regular beam whether rigidly or
elastically supported, as well as transverse oscillations of a hinged beam in the
presence of a constant longitudinal axial stress. It is interesting-to note that
formula (3) coincides with the known results of the theory of electromagnetic harmonic
waves (B.H. Yarovskiy, A. A. Detlaf. Spravochnik po fizike. Gosizdat, Moscow, 1963).
Hence formula (3) has a universal character and it enables structural dynanice to

The author describes a new method of using an electrophotometric
planimeter in the processing of microphotograms. The operating
principle of this device is based on the measurement of the stream
of light equivalent to the given plane. The advantage of this
instnnwnt, besides the simplicity and quickness of its operation,
Is its high precision (measurement error less than 1%) which,
moreoverY cLoes not depend on the form and size of the measured
surface. J.'ne efficiency of the proposed method may be increased

by using two sighting slits with different apertures
consecutivelylin order to reduce the fluctuation of
background brightness. The method of two sighting slits
can also be used in other fields of photomietryy particularly
in measuring star brightness by ineans of electrophotometry.

TEXT: The 70-cm meniscus telescope of the Abastuman Astro-
physical Observatory, which incorporated an objective prism, was
used to obtain a series of spectrograms of faint planetary nebulae
having the following numbers in Vorontsov-Vellyaminov's "Catalogue
of Planetary Nebulae": 2,5.~),129,223,230,237,238,240,266,and also
spectrograms of the planetary nebula xGc 6884. The linear
dispersion produced by the objective prism in the primary focus of
the above telescope was 166 A/mm in the neighbourhood of H Y
Kodak OaO and Ilford-Zenith plates were used with half-hour
exposures in the majority of cases. The star c Per was used as the
standard star, since the distribittion of energy in its spectrum is
well known (Refs, 2 and 3). The star was photographed with
strongly diaphragmed 0 n t r a n c e aperture of the telescope, using
exposures of 3 to 10 m-L". Knowing the energy distribution in

Spec t ropho tome try of Faint Planetary Nebulae
In the case of nebula No.8, the above formula does not apply, since
it does not take intc account collisions of the second kind, which
in this particular case are important, Inspection of Table I shows
that the above nebulae are highly excited ob ects, This is
indicated by the presence of the line X 46M(HeI11 and the relatively
strong line k 3869 [N,IIIJ in the spectra of the~large nebulae,
Apart from the nebula No.8. which is apparently super-delise
(Razmadze, Ref.8), the following objects are noticeable. The
planetary nebula No.129 emits strong lines on X 3727 [011] and
h 4686 [HeII] . This indicates a high degree of excitation of the
medium. The simultaneous presence of these two lines in the
spectrum of the nebula SLIggeStS strong stratification of matter with
respect to the degree of excitation, In the case of nebula No,230,
the lines ESIf] X 4069 and X Ito-116 have high intensities, Their
presence may indicate a very low degree of excitation in the nebula,
This is somewhat contradicted by the absence in the spectrum of the
line X 3727 COI~, which also characterizes low degree of excitatiom
arid the presence of a strong X 3869 E.'XeII. which suggests a high

This may indicate the presence of excess helium in this object.

TEXT: The author reports on an cbservation of a 2+ chromospheric flare as-
sociated with a rapidly varying group of sunspots. The flare was very extended
and was associated wi-h dark ejections and intense radio emission. The flare had
many centers with shifted phases of brightness development. Photometric curves
of development of three flare centers are presented, During the brightness maxi-
mum of the main center, a filament arose In the flare region having a z"ential
speed of 260 km/sec. %rarying rapidly, extending and widening, It a,~tained a maxi-
mum speed of 520 km/sec after whlc..h it remained of the same dimensions during a
few minutes. Later on, the filament began to bifurcate, break to pieces and dis-

ABSTILkCT: The relationship between solar activity and the illumination of the night
sky is investigated. The work was done because previous results have been contradic-
tory. The data were taken from the International Collection of resun-6s of electro-
photo,metric observations of the night sky light of all stations of the earth during
the IGY and IGC. The average monthly and semiannual values for both the ie n. lit
intensities and their maximal values were calculated for emissions of 5577 fo-91

nation of the night sky do not correspond to fluctuations in flare activity. It is
concluded that solar flares do not play a marked role in fluctuations in the

by still other features. All the flares were connected with rapidly clianging,
groups of spots that were either in a stage of development or in a stage of decay.

thouoh some showed a slight lag in tijre. The average duration of growth proved to
be 12 minutes for main centers, 7 minutes for subcenters, and the average decay
period was 24 MinLlteS for main centers, 21 minutes for subcenters. The average

ABSTRACT: This paper consists almost wholly of a set of curves showing the groifth
and decay of the nine largest flares observed in 1959 at the Abastumanskaya
observatoriya (Abastumani Observatory). Data were obtained by means of the AFR-2
chromospheric-photosphericotelescope with a polarizing-interference light filter
having a band pass of 0.5 A in the Hc~ line. The method of photometric treatment
has been described by T. S. Razmadze in the preceding article of the present
bulletin (pp. 3-27). The graphs show duration, intensity, and area. When two
centers were observed in a single flare,, the intenkity and area of each were
plotted, but when the centers were difficult to differentiate, the values for all
centers taken together were plotted* Orige art* hast 3.4 figures and 1 table.

ABSTRACT: Monocrystallinelspecimens of InSb were irradiated with fast neutrons at
100-300*K in a low-temperature horizontal channel of the reactor of the Institute of
Physics, Academy of Sciences Georgian SSR, with continuous measurement of electric
conductivity of the specimens. It was found (Fig. 1) that the decrease in the electric
conductivity of InSb specimens of the n-type at the initial moment of irradiation
occurs at a constant rate and is a linear function of the fast neutron flux. As the
time of irradiation increases, however, owing to annealing and recombination of de-
fects, the rate of variation in electric conductivity decreases. The minimal value
toward which tends the conductivity of specimens of the n-type following prolonged
irradiation is, contrary to the findings of W. Cleland and J. R. Crawford (Neutron
Irradiation of Indium Antimonides Phys. Rev., 95, 1954, 1177), on irradiation with

.ABSTRACT: Results are presented of irradiation of indium antimonide
:with slow neutrons. Although the total cross section for the ab -
"Sorption of thermal neutrons is known for the components in InSb
theoretical calculations are made difficult by lack of data on the

.tion was effected in the experimental channels of the reactor of the

.at temperatures 100 and 300K. The results show that it is possible
to introduce by means of neutron transmutation donor impurities (Sn
.and Te) Into InSb in any desired amount. The final conductivity of
the InSb sample after annealing is governed by the balance between
the carriers present in the sample prior to irradiation and the car-
riers produced as a result of the transmutational doping. Irradiation.,
causes the Hall constant to behave in the same manner as for an or-
dinary substitutional semiconductor. It is pointed out that irradia-,;
tion aimed at producing additional scattering centers has a tendency
to reduce the mobility of the carriers. This effect depends on the
initial concentration of the free carriers, on the degree of compen-
sation of the samples and on other factors. For samples with carrieri

annealing). Fast-neutron irradiation is bound to cause in equal quantities two types
of disorders of the crystalline lattice of the semiconductor: vacancies and intersti-
tial atoms. This complicates the picture of the energy levels of the defects owing
to the appearance in the forbidden zone of InSb of levels associated with the first
and second ionization potentials of vacancies and intermediate atoms* The concentra-
tion of current carriers in specimens of both n- and p-types was'found to sharply
decrease on irradiation. This shows that low-temperature irradiation of InSb produces
donor and acceptor levels located sufficiently deeply in the forbidden zone so that
electric conductivity decreases. The annealing of radiation damage in the temperature
range of 100-300*K confirms the author's assumption that acceptor levels get annealed
much more intensively than donor levels. Orig. art. has: 2 figures, 1 table.
