ABSTRACT:, The procedure of investment casting (IC) employed at the
Gortkiy automobile plant is'described. Over 200 various types
and sizes of tools and parts were converted to production by
means of IC , Including 20 units of 6asic production tools, 36
sizes of hexagonal and square sockets for socket wrenches, 5
sizes of nut wrenches, flat-nose pliers, special nuts. etc.
Comparative data are presented on the work required for the
manufacture of typical forged and cast parts; also stressed is
the decrease of metal waste from 2-3 times and even up to 7-9
times when the IG method is employed.

Abstract Detaile& analysis of the mechanism of the oppradic solar electromagnetic
-radiation, due to bremsstrahlung of relativistic electrons moving in the
magnetic field of the.sun spots over strongly stretched spiral trajectories.
The ratios of the intensities of "ordinary" and "extraordinary" types of
radio waves are calculated for electrons hayinr equal energies and for elec-,
trons with a power-lav energy distribution which, move in the sunspot magne-
tic field that dimijAshes with altitude above the photoophere, and which ra-
diate in the coronal electron-ion gas. Depdnding on the frequency of the :
radio waves, the author outlined the boundaries of the regions of the solar
corona above the sunspots, where the relativistic electrons radiate effect-
ively the "ordinary" and "extreordinary" waves. The intensity ratio of the.

Abstract Experimental data,indicate.,the existence of several types of radio waves:
those-radiated from the "quiet" sun (type I) and sporatic radiation which-
includes radiation due to sunspot (type II)) short-duration flashes not re-
lated to the appearance of solar activity -- "isolated" (type III), and flashes
c1te to chromospheric flares (type IV). Radiation of relativistic electrons,
moving along,the magnetic flux lines, may explain the properties of radia-
tions of,type II. To explain other types of sporadic radio waves from the sun,
a plasma-~nechanlsm hypothesis Is proposed) by which electromagnetic disturb-
ances may become reinforced,under certain conditions In the electron plas-
of the solar atmosphere. Various theories of this types proposed by several
authors, are analyzed. It is qhown tbAt in isolated plasma kwitbout exciti

waves in the corona is quite possible. ThOpossibility of the longitudinal
wave
a becoming transformed into transverse ones is considered, as are the
'conditions under which th~ radio waves can leave the corona. If waves propa-
gate in p3 located in,a. naghetic'field) the radiation may be "sucked
out's from the coroua region (taking into account the thermal motion of the
eleAxons). If the plasm wave propagaten at an angle to the direction of
the gradient of the &lectron concentration, the radio waves may leave the
corona also in the absence of mapatic fields. Such a wave may be produced
under,the'influence of an external agent. Tk the action of the agent is of
short duration) the radio waves will also last a short time (type III of ra'-
distion ). Radiation of type IV is apparently produced by stream of fast
pirticles, which excite plasma waves. The works in which the drift of the
plasma is believed to be the energysource causing the growth of the waves,.
is critically reviewed. 'In the discussions, I.S. Shk1 vskiy emphasized that
the restilts of the observations indicate that na,one mechanism is capable of
explaining all types of radio waves~ although most phenomena are apparently
dilee to plasma oscillations. V.L. Ginzburg indicated the difference between.
the mechanisms of radiation of relativistic electrons from the galaxy and
from the sun; in the former casethe angle between the electron velocity and
the magnetic field in large, and in.the second case it is mr-13. Biblio-

ABSTRACT: This survey discusses the mainly from 1953 to 1957 published
works on-the theoretical and experimRntallexamination of the
radiowave-radiation of the sun and the planets. The first
paragraph details the experimental data on the radiawave-
-radiation of the sun. First a report is made on the radio-
wave-radiation of the "quiet" sun. The measurements of the
intensity of this radiation speak in favour of the existence
of an lower limit of intensity, which usually is regarded as
the level of the "quiet" undisturbed radiation. The
intensification of the radiowave-radiation in general is
connected with the occurrence of active zones on the sun.
The "quiet" sun does not radiate with equal intensity on
all frequencies. The radiowave-radiation in the meter-rouget
which in connected with the sunspots, correlates well with
Card 113 the area of the spots, which are situated near the central

meridian(in case of ahorterwaves ivith the density of the
spots, which are visible on the sun-disk). A great amount
of experimental data is given and discussed~ The intensity
of theradiowave-radiation, which is intensified because
of the perturbations on the sun ' decreases with increasing
frequency. On the background of the radarrove-radiation
many splashes with different "life", i ntensity, and
spectrum of frequency appear. Such a splash occupies at
every momenta limited and in general quite narrow interval
of frequency. Many details are given here additionally. The
second paragraph deals with the theory of the radiowave-
radiation of the sun, it reporto on the theory of the
thermal and sporadic radiowave-radiation of the sun. The
third paragraph deals with the radiowave-radiation of
Jupiter, Venus, and Mars. Here the author reports on the
observations of the radiows.ye-Radiation of the planets, and
on the hypotheses concerning the origin of the sporadic
radiowave-radiation of Jupiter and Venus. The totality of
facts, discussed in this worky does not givea sufficiently
complete idea of this phenomenon yetj which can be said in
particular of the radiowave-radiation of the planets.

TITLE: on the, origin ofthe slowly varying component of
solar radio 'emission
PERIODICALS-Astronomicheakly zhurnal, v.39, no.l$ 1962, 5-14
TEXT i The author,ls.concern6d with the origin of the slowly
varying component,of solar radio emission which is observed
mainly in the wavelength range,l,- 30 cm. A detailed survey of
published information is given and it is concluded that it"is now
established-that the slowly varying component in the above wave-
length range with T eff -C 106.. oK can be jooked upon as thermal
radio emission of co ronal regions with T -'.106 OKI located above
groups of sunspots and plates. on this point of view,, the
observed upper limit ot.theeffective temperature, namely
1.5 x 106 OK is naturally-explained by assuming that the.
erfectivetemperature-cannot be greater than the kinetic
te-inerature in the emitting layer, It is pointed out that

according to W.N. Christianson, J.A. Warburton and R.D. Dayles
(Ref.2t Austral. J. Phys., v.10, 491, 1957) the effective
temperature of thermal rAdiation'from a layer heated to a
temperature T depends only,on the optical thickness of the
layer. In the corona-and in the chromosphere the optical thick-
ness is determined by absorption due to close collisions between
charged particles and also resonance (synchrotron) absorption
during the.accelerated motion of particles in a magnetic field.
Therefore, the optical thickness consists of two terms, ie.
a collision term and a resonance term. it is shown in the
present paper that the properties of the slowly varying component
can be explained by the_.resonance (synchrotron) mechanism
immediately above sunspots and by the collisional mechanism at
-larger'distances from-the sunspots. This approach leads to the
correct-results,for the effective temperature, the radio
brightness distributiong thedirected nature of the emission,
the sign of the polarization, and the dependence of the degree
of polarization on frequency. The synchrotron absorption occurs
at simple multiples of the Larmor precession frequency,,

experimental studies arenecessary. For example, there is no

emitting region andthe intensity of the magnetic field in
sunspots. This correlation'should, clearlyo exist if the present
theory is correct. A furthercorrelation which is of interest in

TEXTs Noncoherent mechanisms of sporadic solar radio
-emission are reviewed,~taking into account the influence of the
magnetic field. The emission is c9nventionally described as
noncoherent when it is possible to sum the emission intensities
due to separate particles (taking re -absorption into account)
but the intensification of the waves.in the system itself can
~be ignored (for example, in a stream of particles). It is
shown that noncoherent m chanisms
e can be responsible for the
intensified radio emission above sunspots and for burtsts of
typeslV and V. Bur-sts of types.1, 11 and XXX cannot be
