single point of the mentioned spectrum lies in the open right side half-
plane, then there exists a system of bounded boundary values for which the
corresponding homogeneous boundary value problem has an unbounded solution.

PERIODICAL Doklady Akad. Nauk 108L 770-773 (1956)

The author considers differential boundary value problems in the complex
Banach space under the assumption that the right hand sides and the initial
conditions are continuous functions of n real variables tl,...,t and their
range of values belongs to the mentioned Banach space. Spectral attributes
of stability (Rutman, Doklady Akad. Nauk 101, 6, (1955)) are extended to some
differential equations with non-stationary linear operators. A boundary value
problem is called stable if to all.(compatible) initial conditions and right
hand sides being uniformly bounded with respect to the norm, there corresponds
.a solution which also is uniformly bounded with respect to the norm. The
principal result of.the paper is the following theorem: Let be given the
boundary value problem

PERIODICAL Uspechi mat.ffauk 12' 1, 234-238 (195T)

The author considers some partial linear systems of differential equations
in the Banach space. It is assumed that the independent variables vary in
infinite intervals. For the increase of the solutions of the considered
equations exact estimations are given. From these estimations criteria of
stability in the sense of Ljapunov can be obtained. The obtained results
base on earlier general investigations of the author (Doklady Akad.Nauk 101,
no.2 and no-6 (1955)).

ABSTRACT: A hydraulic pres.4 -.ras installed at the Podol'sk Plant, on which
ben of kaolin- and highly aluminous fire clay have been pressei
for some time. The press concerned is a vertical press zrith four
columns and a pressure of 900 t, diameter of plunger: 625 mm, and
a stroke of 985 mm. The liquid is pressed int; the cylinder by
means of a 3-plunger pl-,mp, the output being 25 1 per minute, Md
maximum pressure 300 atmospheres excess pressure. The mass is
weighed before pressing and is conve;red into the mold by means of
a device which was designed by P.V. Shabanov and N.M.Semenov, Cal-
culating engineers of the above plant, and rdiich is described in
short by the authors. Before introducing the substance, the mold
is coated with an emulsion consisting of 90;'0' petroleimn, 55/6' 3tearin
and 5% so-ap. Pressing is carried out in three stages: at 40, -120

pressure wnounting to 370-400 kWcm2. The products are e4ect-_d f
the mold by a special device, while the process of removing them
from the press and placing them u on -the lorries is carried out by
means of a lifting device (fig. 15, which rras developed and prc-
du3ed by P.P. Podshivalov, calculating engineer of the above plant,
and which is described in detail. The kaol.-Ln- and highly aluminous
fire clay for glass beams is obtained by burning briquettes from
revolving furnaces. The characteristic of the mass may be seen from
table 1. The output of the
I press amounts to 38 beams per shift
5 t) , the press being operated by 21 men. By pressing it vras pos-
sible to improve the quality of the beaus, which is shown by fig.2
and table 2, where a comparison is drawn with a rurning method. The
physical value3 of the burned beams are shown in table 3. There are
2 figures mid 3 tables.

ABSTRACT: This Author Certificate presents a semiconductor frequency converter made
as a circuit with direct coupling using thyristors. The design improves the shape
of the output voltage curve. Two auxiliary locking units are used for the forced
commutation of the thyriators (see Fig. 1). Each of the locking units includes a
direct current source which is connected in aeries with a fully controlled switching
element, for example, a silicon controlled gate.,

TEXT: To replace motor-genarator charginS sets tYPe
(AZD-11/30), which weigh about 460 kS for an output of 4 k1*1, there
has been developed a semiconductor charging set'itype -, IjI
(ZUG-1) which ureighs 90 kg and has an output of 4.2 IcV. It is
supplied from a three-phase 380-22C1 volt circuit with a continuous
current rating of 70 A and has an output voltage which can be
controlled in Stepsof'3 V from 60 to 77 V and an efficiency of
94-95`,",. The rectifier set uses six air-cooled germanium elements
typed 1" -10 (VG-10) and is trolley mounted. Supply voltage is fed
through an automatic high-speed circuit-breakez- to a two-winding
stepdown transformer-which supplies the germanium rectifier
connected in three-phase bridge circuit. The voltage is controlled
by a number of tappings on one phase secondary winding of the

transformer. Charging takes place automatically with a current
which diminishes in value as the charge proceeds, the value at.the
end of the charge being set by a switch. With this equipment it
is not necessary to determine the state of discharge of the
battery before connecting it for charge, because the charging
current automatically adjusts itself to the appropriate value for
the given degree of discharge. This is achieved by having in the
rectifier output a non-linear resistance made of soft steel wire,
which also protects the rectifiers and transformer against
prolonged overloads. A high-speed fuse type -riG-2 (PNB-2) and a
high-speed circuit-breaker provide short-circuit protection.

au/ax, Ou/ay tend to zero when x - I M and y -> w. By applying the Laplace
transformation with respect to t to this boundary problem and after Fourier trans-
formation with respect to x, the differential equation (1) is reduced to a second-
order ordinary differential equation for the Fourier transform U(y) and the initial
and boundary conditions to corresponding initiar and boundary conditions for the U(y).
The general solution of the reduced boundary-value is derived and the problem of
determining unknown functions is analyzed. It is shown that the final solution of
the defined boundary-value problem can be derived with the aid of contour integrals
whose evaluation, however, is difficult. To simplify calculations, the second
approach is used. By applying the inverse of the Fourier transform and utilizing
certain tables of the operational calculus, the boundary conditions are reduced to a
new form. The solution of the boundary-value problem for equation (1) with initial
condition (2) and transformed condition can be found with the aid of Green's functiom

having regard to the relatively short pipe lines in aircraft
power systems. In view of mathematical difficulties, a vibration
test rig was built with forcing frequencies of 25, 50, 75', 100, 125
and 175 cps, which are the resonance frequencies of cantilever
springs. The range of liquid flow was between 1 and 4 m/sec.
The vi.brating, tube which may be, straight or coiled is connected' by
two hose lengths to the hydraulic circuit, wherein the feeding and
collecting tanks both have free liquid surfaces so that the pipe
vibrations are not overshadowed by hydraulic circuit vibrations.
The general level of pressure Is maintained by compressed air.
The vibrations are induced by an electroma gnetic system. The
pressure is measured with a capa ci tiv~,. pre s sure transmitter. The
fluid flow, the vibration frequency, 'the vibration amplitude and the
fluctuations in the fluid pressure and its rate of flow were
continuously recorded during the exp6riments. Several results of
these tests are plotted and discussed.' The work is stated to be
nroceeding and the numerical results described must be regarded
as significantly affected by the mechanical features of the
installation rather than possessing a general validity. The only

1955. The scientific supervisors were Professor A.V.Kvasnikov and Docent
D.I.Agubov. The first paper describes the development of a new method for
measuring rapidly changing.. pulsating temperatures as in the case of internal-
combustion engines., particularly in high-speed machines with poor pressure-
indicator accuracy. The method proposed by the authors uses a pickup with
obviously high thermal inertia vhich inaccurately records temperature with
respect to time. The second paper investigates the discharge of a gas from
nozzles in the turbo-conrpressorr. of compound engines, answering tvo min
questions: a) Inie deflection of the flav in an oblique cross section of
single nozzles and narrowly-spaced nozzle lattices for supercritical condi-
tions; b) the critical flow regime in tvo-di nsional nozzle lattices. The
third paper discusses the problem of simulating the operating conditions of
poverful turbo-machines by maintaining the original shape and replacing the
,full-scale working parts by others with onlya part of the original pover.
,The report also presents experimental data which confirm the validity of
the method.

ABSTRACT: Previous experime-nts have shown that it is possible:to set,
up regimes in which the combustion zone is located at the wall of them
combustion chamber rather 'than in the central section as in conven-
tional regimes. Such a regime was studied iA chambers with and without
vaned inserts by obtaining profiles of the temperatures, liquid and
vaporized fuel concentrations, and flow velocitie's.. It was found*'that

in-this regime, combustion of the annular air layer containing fuel
vapors and droplets starts from the outer surface of the layer which
is not adjacent to the recirculation zone. This situation appears to
be favorable for obtaining improved temperature profiles at the cham--
ber outlet. The flow resistance is also lower, since secondary air
;-Jets do not have to-penetrate into the'axial combustion region as is
-the case with a conventional location of the combustion zone. How-
,.ever, a tendency'to os~qillatory burning was observe d. Ori$. 'Art. has:
