Translation: This Author's Certificate introduces a television device for
-classifying colored objects and images. The device contains a black-and-
white transmitting camera with a rotating light filter disc, and a vidicon
camera which delays the video signal for the time of one half-frame. As a
distinguishing feature of the patent, resolution is increased by connecting
a first commutator between the black-and-white transmitting camera and the
vidicon video signal delay camera, one of the outputs of this commutator
being connected to the vidicon while the other is connected to the first
inputs of four weighting adders. The commutator input is connected to the
output of the black-and-white transmitting camera, while the second inputs
of the four weighting adders,are tied in.pairs and connected through a

Translation: This Author's Certificate introduces: 1. A device for ana-
lyzing the color of an object- The device contains a three-color video
vignal pickup with three calorimetric ligbt.filters, modules for display
and for illumination of the object being studied, and a timer connected to
the pickup and to the display module. As a distinguishing feature of the
patent, the device is simplified and speed.is increased by connecting an
analysis module between the three-color pickup and the display module.
2. A modification of this device dist-Inguished by the fact that the analysis

module contains amplifiers, add rs, threshold circuits, NOR logic circuits,
and a two-coordinate matrix based on MID circuits. The amplifiers are joined

the amplifiers in each group being connected to the corresponding input of
the analysis module. The outputs of the,amplifiers of each group are con-
nected to the inputs of the adder of the same channel. The output of the
adder of each channel is connected through an addition subtraction circuit
to the corresponding threshold circuit, which is cormected, in turn, through
a NOR logic circuit to the corresponding'line of the t-vro-coordinate matrix.

"Investigation of the Effect of Temperature and Viscosity of a Solution on
-Concentration Depolarization of Fluorescence
Minsk, Zhurnal Prikladnoy Spektroskopii, Vol 18, No 4, Apr 73, pp 653-659
Abstract: The influence of the temperature and viscosity of a solution on con-
centration depolarization of fluorescence is theoretically studied on the
basis of an examination of diffusion of fluorescing molecules. The computation
is based on the "active sphere" model of Jablonski's theory (Acta Phys. Polon.,
Vol 14, 191-5, p 295; Vol 17, 1958, p 48. Formulas are found for the aniso-
-tropy of emission as a function.of concentration, tenperature, and viscosity
of the solution; these formulas are compared with Jablonski's formulas for
stable solutions. This comparison is used as a basis for Tv-aluating the influ-
ence of diffusion on the anisotropy of fluorescence enarsion. The theoretical
relations are checked out on a high-precision photoelectric unit. Some of the
causesof discrepancies between theory and experiment are discussed.

lx~.a-orgarizad by the Ministry of Higher and Secondary Special &ducation and was
held at tho.14oscow Higher Technical School on 10-13 Iiarch 1970. The agenda pro-
vided for 12 workin- sections. The "Welding, soldering, gluing" section opened
with a report on ultrasonic welding, bone tissue built-up, anI the cutting; of
biological tiss-aes. This report,by G. A. Nikolayev, described tae resulL5 of
more than 340 successful experiments on animal's. Thirty-seven reports and coin-
ri.anications wore presented in this section. Five reports dealt with proolems re-

creasing reliability in spot welding, ultrasonic contact welding of plastics,
eloctror. boaa, welding, welding of steels and alloys, automatic welding, ar4 tile

OBasic Equations of Blood Hydrodynamics"
Nauchn. tr. In-t mekh. Mlosk. un-ta (Scientific Works, Moscow University In-
stitute of Nechanics) 1970, Z40: 1, PP 3-20 (from RZh-',-[ekhanika, No 2, Feb 71,
Abstract No ZA18)
Translation: Blood is a mixture of a liquid plasma and su5perded particles
the great majority of which are erythrocytes. The rheological characteristics
of the blood depend essentially on the concentrationof the erythrocytes and
on the materials dissolved in the plasma which influence the deformation of
the erythrocyte envelope and coagulation. Experimental investigations have
shown that blood is not a Newton-tin liquid since formwLtion of zones free from
particles (the wall effect) is observed in its flow through tubes, and there
is a rise in concentration in some annular laver within the tube (tne axial
effect). In ordinary Poiseuille flow,the particle concentration does not
vary over the tube cross sectioni From several assumptions of the character-
istics of blood, a model has been constructed -with internal degrees oil' free-

RZh-Hekh, 1970, 4B1063). Here, the disc ussion is given from the point of view
of conformity to the exDerimental data. A plane Poiseuille flow is considered.
The problem is solved with an electronic computer by the method of finite dif-
ferences. The results obtained for the concentration distribution snow that
the proposed theory indicates a drop in the concentration near the wall. With
a proper choice of migration factor values, an axial effect can also be quali-
tatively obtained. in the same way, confirmation is obtained of the theore-
tical-fact that at large particle concentrations only the wall zone is formed,
while for small concentrations only an axial effect-is observed. From in-
vestigations of the Couette flow, the conclusion is drawn that for large values
of average particle concentration no phase stratification is produced, except
for a slight drop in concentration close.to the wall.which agrees with the
experimental fact. A qualitative comparison of the results of the problem
solutions on the basis of the given equations with the experimental data in-
d1cates that in the framework of the proposed theory, all the effects observed
in the blood and in other suspensions of similar structure reinforce the des-
cription for stationary flows. The theory does not predict arty side effects
which might contradict experiment or existing concepts of suspension movement.
Some ideas regarding improvement of the proposed model are offered. Biblio-

in the acceptance of one of two hypotheses with a defined risk, or in the
acceptance of both hypotheses if the text has,been fully inspected and the
conditions of selection have still not been.met. The method suggested is
illustrated with examples. A method is given for analysis of the criteria of
selection. A block diagram is presented for an algorithn, for -text attribution

"Sectoral Horn Radiation"
Moscow, Radiotekhnika i Elektronika, Vol 17, No 10, 1972, pp 2035-2042
Abstract: A study was made to establish the correspondence between the Lwo
methods used to calculate the radiation of sectoral horns -- the Kirchhoff
method and the method of the greometric theory of diffraction r- and also the
correspondence between the two versions of the method of the geometric diffrac-
tion theory - the method of successive diffractions [V. A. Borovikov, Diffrak-
tsiva na mnogougol'nikakh i innogogrannikakh-1 Nauka Pressv 1966] and tile self-
consistent field method [B. Ye. Kinber, Radioteklinika i elektronika, Vol 9, No
9, 1594i 19641. In both versions.the solution:of the problem is formed as the
s4erposition of a set of diffraction problems of directional (standard)
irylindricaI. waves on halfplanes -- the edges of a horn. The number of standard
waves used defines the accuracy of describing tile interaction of the edge waves
and, in the final analysis, the accuracy of calculating tile field. The effect
of this factor is also evaluated. The results of som, numerical calculations
are presented indicating that the self-consistent field method is the best.
The Kirchhoff method gives an error on the order of several percentages.
