pp. 927 - 930
TEXT: A description is given of the construction of a
synchronolis motor working in conjunction with a quartz clock,
which can be used to obtain simultaneously one-second pulses
of both solar and sidereal times-IVThe principle of the motor
is shown in Fig. 1. The stii-~-r-o-f the motor is supplied from a
1 000 c.p.s. source and brings into motion the shaft 1 of the
rotor. This motion is transmitted to the second-shaft through
a 1:10 gear. The latter executes 86 400 revs. per average solar
day. The rotation of the shaft 3 is transmitted to the minute-
shaft 4 through a 1.60 gear. With the aid of the-cam 6 .
contact 7 , the gear, 8, 9 and the adjusting knob 10 t it is
possible to obtain second-pulses of the mean solar time and also
to phase them in the required fashion. The minute pulses of the
mean solar time can be obtained with a similar arrangement shown
at 1.1 . Another mechanical device coupled to the main shaft 3

Statistical Check in Case of
ment of the Grouping Center

a Systematic Displace-
Towards One of the Limits
Metalurgia ~i Construc~ia de Maqini, 1959, Nr 12,
PP 1053 - 1064
ABSTRACT: There are factors in systematic production which de-
termine a systematic increase or.decrease of the
characteristic values, i.e. a shifting of the control
centeii4either towards the upper or the lower limit
of the tolerance field. This article presents the
method of applying a statistical check in such cases.
The purpose of this check is to establish how long
a machine tool can operate without resetting. The
Card 1/4 authors explain the calculation problems of the check

Statistical Check in Case of a Systematic Displacement of the
Grouping Center Towards One of the Limits of the Tolerance Field
limits and the establishment of the statistical
checking slips. After determining the equation of
the displacement line of the grouping center and com-
puting the time a machine tool can operate with the
same tool setting, the authors calculate the check
limits. Starting with the equation of the dis5lace-
ment line of the control center (E uation Nr -
the value of the dispersion field Muation Nr 2');
and the characteristic values of the deviation
against the control center line (Equation Nr 3), the
authors establish the dispersion formula (Nr 6). If
the control center moves towards the lower limit of
the tolerance field, the lower limit of the disper-
sion field will, after a certain time, reach the
lower limit of the tolerance field. This is the
moment when the tools of the machine have to be re-
set. The time which separates 2 successive reset-
Card 2/4 tings can be computed by cutting the lower limit of

the dispersion field by the lower limit of the tole-
rance field. The measurements supplied by the parame-
ters of the samples, taken periodically from the pro-
duction of a certain machine tool can be used for the
supervision and direction of the technological pro-
cess. Two parameters are used: one supplying informa-
tion on the accuracy, the other on the tool-setting
state of the machine. The authors then describe the
supervision of control by the checking diagram which
is established in the following order: establishment
of the equation of the displacement line of the con-
trol center; determination of the width of the dis-
persion field; establishment of equations of the
limits of the dispersion field; calculation of the
duration of a control; determination of the para-
Card 3/4 meters which will be used for the characterization

alloy of niobi um (65%), titaniun 7( 15%). and zirconluT,.( about 9%), the
remainder being her components selected for their metallurgical
properties. The critical temperature of the material is 9.8-10K.
Because of its relatively low brittleness, the 0.25-mm o.d. copper-
plated wire could be drawn by Rtandard methods into four-kg coils

in a helium atmosphere, both types of wire were coated with a polyester
varnish to add a 0.03-mm layer to the diameter, The magnet, with a
16-mm inner diameter, consisted of 3 concentric sections wound onto
aluminum-alloyed former The inner section alone, using 17,762 turns
of vacuum cold-worked wZ;J generated 65,000 oe; the two other sections
made of 15,210 and 10, 0 turns of wire cold-worked in a helium
atmosphere, and wound on a common former, generated 43,500 oe. The
maximum magnetic-field intensity of the magnet was 76,300 oe. Even

PERIODICAL: Zhurnal prikladnoy khimil, 1960, Vol. 33, No. 7, pp. 1669-16'71
TEXT: Cadmium-plating from acidic baths by means of current reversal
effected by a variant of A?T-2 (ARr-2) electronic breaker (Ref. 3) was investi-
gated. The duration of the anode (t a) and cathode periods (t ) was regulated
independently of each other. The deposition was carried out 2Sn brass samples
and partially on copper samples with a total surface of 4 am . The thickness
of the coatings was 10-2OA4. The anodes were made of chemically pure cadmium.
The range of current densities was 0.5-4 amp/dm2. The bath had the following
composition (in g/1): CdO 19, KHS04 45, (NH4)2SO4 10. The structure of the
deposit is affected by the to

the appearance of the deposits obtained by current reversal does not differ from
those obtained by d-c. In the presence of naphthalene mono- or disulfoacidz
with gelatin, mirror-lustrous cadmium deposits were obtained. Caramelized
sugar still improves these results. From a cyanide bath finely-grained, dense,
light doposits were obtained, but without luster. Cadmium deposits from
acidic baths have a microhardness twice higher than deposits from cyanide baths,
their porosity is 5 times lower and the current density can be increased twice.
There are 2 graphs, 2 tables and 5 Soviet references.

TEXT: The present authors are concerned with identifying Class 11
radio sources with individual galaxies. The review is based on
published catalogues and lists of radio sources. Radio sources ly-.
ing in the plane of the galaxy and also weak sources were excludel.
The final list consisted of 390 objects. In order to establish the
presence of a physical relation between the radio sources and clus-
ters of galaxies, a count was made of the number of coincidences
between them, and this was compared with the corresponding mathe-
matical expectation of coincidences, assuming a uniform random
distribution of both types of objects. This analysis led the auth-
ors to conclude that the majority of identified cosmic radio sour-
ces of Class II are in fact found in clusters of galaxies. Of 45

member. This is used as an argument against the collidlng-.galaxiea
theory: It indicates that the radio galaxy plays an important rcle
in the life and activity of the entire cluster. Acknowledgments are

ABSTRACT: A new radio telescope system is described. This system consists of two
annular mirror telescopes with very high effective solving power. The main mirror
is a narrow spherical king of large diameter. The normal to the ring forms a small
angle with the horizon. The ring consists of individual elements. The second mirror
is moved on the focal line of the main mirror, and has a diameter equal to half that
of the main mirror. This telescope can examine the sky in a declination belt equal
to 180*-2 0, where 0 is the geographical altitude of the mirror's location. Because!-
of its low position, the coirecting mirror may be moved around the ring of the main
mirror on a carriage. The ring of the main mirror can be illuminated by a restrictedi
area of the correcting mirror and thus a very narrow horizontal directivity diagram L-
may be obtained. Both coordinates of the discrete radio emission source can be 21-

measured by examining the region of sky twice on corresponding azimuths. A radio
emission source can be observed for two hours with a telescope whose diameter is
one kilometer and which is located at 40* latitude when the source is at the southerr
border of the belt scanned, and for one hour if the source is at the northern berdex
Such a high solving power telescope is less expensive to construct than an ordinary
one. A maser with cooler can be added to this telescope. This telescope may be usec
before construction is complete. The ring telescope has many advantages compared
with other systems. Orig. art. has: 2 figures. JEG]

ABSTRACT: A double reflecting annular radio telescope is proposed, guaranteeing a
[high resolving power with significant simplicity and low cost of construction. A
fixed spherical ring of large diameter (- 1 km) and small width, placed on a horizontal,
laUrface, is the primary mirror. The secondary (correcting) mirror in moved along the
Ifocal line of the primary mirror and allows reception from directions of conutant
jelevation angle and varying azimuths. A survey of the sky is carried out in the
!interval of declinations 160--2 q), where (p is the geographic latitude of the point.
jif up to 20 correcting mirrore are installed, then it is possible to make simultaneous
independent observations in many directions and at various wavelengths. The
;diagram in knife-edge and is constant at all azimuths. The resolving power varies
!with varying declinations. The low position of the correcting mirror allows the use
of masera with refrigerating equipment. S. 1%karova Oranslation of abstrac!7

A~FTRACT: A. V. Bitsadzj presented earlier (Izd. AN SSSR, H., 1959) examples of
ellt-iptical systems for which the homogeneous Dirichlet problem within a circle has
aq,tinfinite number of linearly independent solutions indicating that in general the
" lem is not a Noeterean one. On the other hand, the Dirichlet problem for
~Sgnd-order elliptical systems can be normally solvable despite the fact that the
rMogeneous Dirichlet problem may have an infinity of solutions. In this continuation
of an earlier paper (Differentsial'nyye uravneniya, No. 1, 1966) the author investi-
gates the question of whether the Dirichlet problem for the second-order elliptical
system is always solvable, and whether there are Dirichlet problems for elliptic
cases which are normally solvable but not Noeterean. The results show that the class
of elliptical systems for which the Dirichlet problem is normally solvable is wider
than the class of elliptic systems for which the problem is Noeterean or even wider

problem for the Inhomogeneous system with homogeneous boundaries is always normally
solvable within the semi-infinite plane. Orig. art. has: 37 formulas.

ABSTRACT: Let D be a threedimenaional domain in which the Dirichlet Problem
for the Laplace equation has a solution for arbitrary continuous
boundary conditions. On the boundary 15 of D let be defined a
function f(p) continuous everywhere on (5'with the exception of
the point po where it has a discontinuity of arbitrary order. In
a small nei,-,hborhood of p0let 6 have a continuously variable
normal. In a certain riei6liborhood of po lot the straight lines
parallel to the normal in p - p 0 intersect the boundary only once.
Theorem: Under the given assumptions the Dirichlet problem has a
solution for the Laplace equation.
