TITLE: New Mechanical Grinders (No-,yye meklhaniches4lye iszlrateli)
PERIODICAL: Zavodskaya Laboratoriya, Vol 24, Nr G, PP 1154-115F IUSSR)
ABSTRACT; The mechanical grinders ' F.M_'o ' and ' agil ` (big and small) are
designed for grinding rozks, ores, minerals and other materials
with a hardness of 06,5 - 7 (according to M-oos). The operation
of the mechanical grinders is based on a new kind of power trans-
mission from the electTomotor to the pestle. The latter moves
radially and circularly from, the edge of the plate to the center,
and vice versa, rotating around its own axis at the same time.
The grinder is dcscribed and shown in a figure. Samples of dif-
ferent hardness, 'Like granite, quartz, basalt, diabase, marble
etc., were used for the laboratory and industrial tests of these
grinders, The experiments showed that a certain ratio of the
sieve fractions is obtained already after 3,0 - 3,5 minutes with
weighed portions of 20 g, and after 10 -- 12 minutes with weighed
portions of up to 100 g. Within this time Dractically the whole
material is ground to -200 mesh (76jk). The two types of grinders
mentioned above began to be produced in series at the sistema

ABSTRACT: It is recommended to carry out physical and mechanical tests
of plastics according to the determination of the elasticity
modulus on the basis of bending deformation at low temperatures
which was worked out in the NIIPP-Lenin,~;radskiy nauchno-
issledovatellskiy institut polimerizatsionnykh plastmass
(KIPP-Leningrad Scientific lesearch Institute for Polymeri-
sation Plastics). A footnote of the edit3r (of the present
publicationy says that the coefficient determined by the test
method which is described by the author, cannot be regarrInd as
elasticity modulus, but that It still enn be used for a suitit"ble
evaluation of the material properties. This modulus charac-
terizes the behaviour of plastic dependence or temperature

TEXT_,', The effect of alcohols on the electrostatic charge forming on high-
densd-ty polyethylene (HDPE) was studied. Alcohols were obtained by oxo-
synthesis of unsaturated products of petroleum cracking. Oxyethylated al-
cohols had the general composition C E , where C is the initial alcohol

ABSTRACT: Dielectric strength of thin Teflon, polystyrene, and styrene copolymer
films in heterogeneous and homogeneous electrical fields was investigated. The
study of the breakdown phenomenon Is complicated for such films since the structural
heterogeneity, impurities, etc. at small thicknesses become more pronounced, as was
observed by P. N. Shcherbak (Plast. massy, No. 9, 40-43 (1963); ibid. No. 3, 6G-64
(1951); Ibid., No. 10, 51-57 (1962)). This results in a wide Ir ad of values for
.dielectric strength from several hundreds of kw/mm to a few ;:/M:or "zeron values.
From a study of 4880 breakdowns in the above materiala the following conclusions
were reached: 1) for an objective evaluation of dielectric strength of films less
than 0.03 mm thickp exposure of weak spots, and selection of the optimal number of

tained', in addition, Nb and Mo. The wetting at various,temperatures
was traced by means of a motion picture camera, and curves showing
the dependence of the contact angles on temperature in various.frit-
to-metal combinations were obtained. The effect of the addition of
?1003, CuO, CUO + "203, Sb2O3, W03, or C0203 as surfactants in one,
of the heat-resistant frits was tested. The results of the study,
indicated that the accuracy of readings depends on many side pheno-
mena, such as crystallization, bloating, phase separation, oxidation
of metal, and the melt interaction with the oxidized metal. However.
since these phenomena also take place in the actual coating process,
the data obtained in the study can be used forthe evaluation of the
relationship between the wetting and the adhesion. The experiments
conducted indicated that the wetting depends both on the metal and
frit. Low-melting frits wet the metal well, but they have poor ad-
hesion. The addition of Cr203 to a heat-resistant frit improved the
contact angle and eacilitated the sintering and spreading~on metal;
an increase in Cr203 content in low-melting frits increased the con-
tact angle and the strength of adhesion. The introduction of a sur-
factant improved the wetting and sintering, but did not change the A.

adhesion. Other conditions being equal, high-melting and poorly wet-
tin& frits have a better adhesion to-metals than low-melting frits...
The poor adhesion of the low-melting frits seems to be caused by in-
sufficient metal oxidation under a rapidly sintering coating, while
a high-melting and slowly sintering coating provides a sufficient
development of an'oxide film, which promotes the adhesion. The phe-
nomenon was confirmed experimentally. The index of wetting is not
the basic factor controlling the adhesion.. The diffusion of atoms
was found to be an important factor 'in the development of the cche-
sive layer. It was noted that the strength.of adhesion increases
after prolonged service or after test's at high temperatures. The
addition of small amounts.of metal powders to the fr,its is suggested--
in order to distort the crystalline lattice of the coated-metal by
diffusion. Orig. art. has: 5 :figures.

AT-')STP,CCT: This paper treats the diffraction of obliquely incident, arbitrarily po-
larized plane electromagnetic waves by a complex structure consisting of an infinite
plane metallic grating and a parallel plane reflector separated by a layer of mate-
rial with arbitrary conplex dielectric constant and magnetic permeability (magneto-
dielectric). This problem is believed to have practical applications to microwave
antenna and measuring technology, where it is frequently desirable to support a me-
tallic grating or other structure on dielectric material. The incident and reflect-
ed waves and the field in the dielectric between the grating and the reflector are

expanded in Fourier series and the boundary conditions on the grating and the reflec-
tor are expressed in ter=s of the coefficients. The resulting equations are trans-
formed into an infinite set of inhomogeneous linear equations for the expansion co-
efficients by methods expounded elsewhero (Z.S.Agranovich, V,A.Marchenko and V.P.
Shestopalov, ZliTr,32,No.4,1962; A.I.Adonina and V.P.Shestopalov, Ibid.33,No.6,1063).
This transformation involves the solution of what the authors call an inhomo-eneous
conju.-ation problem: to find two functions, one analytic inside the unit circle and
one analytic outside it, such that their difference vanishes on an arc of the unit
cizcle and their num assumes preassigned values on the remaining portion of the cir-
cle. The resulting system of linear equations for the expansion coefficients is con-
ver.-ent and can be solved approximately with an electronic computer. No numerical
results are given. In the long wavelength limit, the equations for the expansion
coefficients can be solved analytically to obtain "equivalent boundary conditions"
for the diffracting structure. These conditions are obtained. When the dielectric
constant and permeability are unity and the reflector is removed to infinity, these
equivalent boundary conditions reduce to those previously obtained for a plane grat-
ing by N.N.Smirnov (ZhTF,28,No.7,1958). Orig.art.has: 29 formulas.

ABSTrv'ICT- Equivalent boundary conditions for the complex amplitudes of the electro7
magnetic field on an infinite plane metallic grating at the boundary between two
magnetodielectrics are derived from the solution of the corresponding diffraction
problem (A.I.Adonina, V.V.Shcherbak,Zli-iF,34,168,1964). The equivalent boilndary con-
ditions are valid tn the Ion- wavelength limit and are obtained by eliminating the
amplitudes of the incident wave from. the expressions for the fi-lds on the grating
with the diffiacted wa;ves neglected. The conditions a~e

!ABSTRACT: A theoretical investigation is presented of inductive obstacles (such &a
ia single strip, a diaphragm, several strips, symmetrical or unsymmentrical)
,in rectangular waveguides. This is a continuation of the authors$ work on
I
i1capacitive strip obstacles (Rad. i elektronika, 1965., 10, 6, 1043) where the
lRiemann-Plilbert method was used. Equations are set up for determining the
!coefficients of transmission and reflection and the amplitudes of waves of
Idiffraction spectra when an Hpo-mode falls on the above inductive obstracles. The
,equivalence of inductive obstacles to a strip lattice of a suitable configuration
is demonstrated. Numerical calculations show that the symmentrical strip is
shunting the waveguide to the highest and the symmetrical septum to the lowest
:degree. The results may be extended over any node falling on an inductive obstacle.--

ITOPIC TAGSi rectangular waveguide
ABSTRACT: The Riemann-Gilbert method developed for solving metal-gratin.- diffrac-
tion problems is used f32 investigating the inhomogeneities in a rectangular
waveguide. The problem of diffraction ?f -modes by various metal-strip
capacitive obstacles is reduced to an infl-ote set of linear algebraic equations
with unknown amplitudes of the natural modes arising at the obstacles. For a
finite number of the natural modes, the infinite set of equations becomes a
finite set; the general form of the additional terms is known which permits
!calculations with a specified accuracy. It is proven that a waveguide obstacle
with any distribution of strips and windows is equivalent to a periodic grating
whose strips and slots in its period aredistributed according to the given
obstacle and its image. Numerical values of the reflection (or transmission)

ABSTRACT: The problem of mode diffraction by a'single-layer metal-strip
obstacle was solved by the authors earlier (Rad. i Elektronika, 1966, v. 11, no. 4,;
675). The present article extends the above problem over the case of two-layer i
("double") arbitrary strip obstacles placed in a waveguide with a spacing between
them. Equations are set up (and solved by the Riemann-Gilbert method fo.
particular case) describing the diffraction of E f and TE Y., modes by the
P. P
obstacles. The modes are assumed to be polarized in a direction parallel to the
slots in the obstacles. A particular case of two single-slot asymmetrical irises
is treated numerically. Orig. art. has: 6 figures and 22 formulas.

are investigated. Starting from Maxwell equations, the author writes expressions
1Or tile field components in each of three regions: prior to the obstacie, w-Linin the
obstacle, and following the obstacle. In the first region, the diffraction field is
represented by tile incident wave and the sum of reflected waves; in the second, by
the sunis of direct and backward waves; in the third, by the sum of the waves which
iiave passed. The use of boundary conditions on the windows and strips of the
obstacle results in four infinite systems of equations with respect to differences
arid sums of direct and backward wave amplitudes. These systems are reduced to
the Rieinann-Hilbert problem whose solution gives an infinite quasi-regular system
of algebraic equations. Reflected and passed wave amplitudes are found on the
basis of direct and backward wave amplitudes determined through the solution (in
finite order) of this system. The existeilce of a link between the results thus
obtained and those presented for single obstacles in other studies (RZhFiz, 1965,
I lZh258, 259) is pointed out, and a method for obtaining results for twin obstacles
from the corresponding expressions for single obstacles is explained. Calculation
data on the amplitudes of fundamental-type reflected and passed waves are presented
for the cases of a double symmetrical inductive strip and of a double asymmetrica r
inductive diaphragm, as a function of geometric parameters. The graphs are of an
oscillatory nature owing to the resonance phenomena in the space between the
systems of strips. [Translation of abstract) [DW]

ABSTfRACT: The formulation and solution of the isoperimetric variational problem is
given to determine the shape of a supersonic airfoil cross section which will en3ure
a minimum average heat transfer coefficient for given aerodynamic characteristicq.
The solution is given for Mach numbers 7--8; the flow is assumed either fully laminar
or turbulent, where the local rriction and heat transfer coefficients are calculated
using flat plate formulae including local magnitudes for the flow parameters. The
calculations show that, in comparison with the flat plate, the ma imun local heat
transfer coefficient is lowered by 80-85/110 and the average heat transfer coefficient
by 157/6. A. M. Gubertov ZTranelation of abstract7

ABSTRACT: This paper deals with the problem of determining the optimum shape of a
J--qupersonic wing with given aerodynamic characteristics (I:Vt Wjal drag, lift-
drag ratig-,ete.) which minimizes the average heat-trin"de'Y t4ffic-ient. The
problem is reduced to dete--mining the function y - y(x) of the characteristic
line of a thin profile which ensures the extremum of the functional of the average
heat-transfer coefficient at given values of drag coefficients. This isoperimetric
variational problem is solved by using indeterminate Lagrange multipliers.
The solution is presented for the case when lift and drag are given, from which the
solutions of other particular problems may be obtained. It is assumed that the
lower and upper surfaces of the thin profile are thermally insulated from each
other and that the boundary layer is totally laminar or totally turbulent. The

local heat-transfer coefficients on a slightly cambered profile were determined by
substituting the local flow parameters in the formulaa obtained for an isotherml
toplate" at zero angle of attack. The results of calculations made by using the
formulas obtained by F. Davies and R. Monaghan are given in graphs and analyzed.
