Abstract: A study was made of the affect of ethyl bromide on the corrosion
cracking of.D16AT alloy. A method and a device are descr4bed for separating
the thin-layer anodic film fron the~surface of this, alloys The anodic filir,
entirely located in the pure aluminum cladding layer 60-62 microns thick was
-5eparated in a glass device. The specimed 'Was droppedi itI a M-250 mZ cylinder
the ends of which were free of metat containing 1.00-120 m.2. of ethyl bromide.
The alloy begins to experience noticeable corrosive solution alter 20-22 hours
of heating (not exceeding 40'. C in vievT of the boiling point of ethyl bromide),
and it dissolves completely after 30-38 hours. Tht! corr4njioa products are

Abstract: A transducer is suggested for local measurement of the ionization
current in a turbulent flame. The signal of-the transducerdepends linearly
on the concentration of ions at the boundary layer of the measuring element
of the transducer. The magnitude ofth6sigiial depends,ton the velocity
of movement of the gas and the temperature Iof the measi* ing vlement. Analy-
q
sis of the natunof the signal produced in a homogeneou's laminar flame, a
turbulent flame and the deep zone of a turbulertflame.,~Indicates that
where the flame is actually turbulent, the,method is qualitative in nature.
The method is suitable for study of the flaine front inia stable flow when
the measuring element of the transducer.is not:heated,!~and pressure pulsa-
tions are slight.

pp 97-103 (from RZh-Fizika, No 12(l), Dec~70, Abstract No 12D1328)
Translatio In the development of.especially.high dispersion, homogeneous am-
monialess emulsions of the EVR-1000 type (d 0.03 v), there 4rose the question
of its stabilization. A basic difficulty,in the stabilization. of such an emul-
sion is in preventing the recry--jtallization of the emulsion and the appearance
of hidispersion of microcrystals associated with it. In ithe absence of sta-salt
the m-ist considerable concentration of bromide (pBr = 6.11) in thermostatically
controlled aging of the emulsion was sufficient for the g,jse of bidispersion,
and its rise was accompanied by a sharp changed in the photographic properties
(a drop.in gamm;~ and a rise in light se i Ivit
ns t y). The introduction of 2,61-10
mole of sta-salt per liter of emulsion fully stopped riemlstallization even for a
considerable concentration of bromidei Tho.concentration of bromide that is

'Precision and Reliability in Yeasuringwthe Position of a I'wo-Dimensional
Object on a Plane"
Moscow, Radiotekhnika 1 Elektronika, Vol 17, No 4. Apr 72, pp V-4-720
Abstract. The author considers the problem of determining the planar po-
sition of a two-dimensional object observed against a background of ex-
traneous objects and Gaussian interference. : A criterion is formulated for
the weighted mean-square measurement error together with an optimum rule
of measurement. Relations are deriv~ed for calculating the weighted meen-
-square error uthen the spectrum of the object is known as well as the in-
tensity of interference. Relations are found for the probability of false
identification of some object with an extraneous object. For,.special cases
where the number of extraneous objects is ~ great:, conditions axe formulated
which must be satisfied to keep this.probability low.

Abstract: The authors, members of IPPI (Institute of.Information Transmission
Problems) of the USSR Academy of Sciences, conducted an, experiment on the
Minsk-22 digital computer for the purpose of-reproducing the-image of an. object
from its hologram developed from a Fourier.system. The,results of this exper-
iment, described as the first step in the use.of a computer for this purpose,
are given in the present paper. A hologram made in the4*~A. F. loffe Physico-
technical Institute was used in the experiment for the purpose of investigating
the~possibility of transmitting holograms over a photo to legraphi c channel. The
basic stages of the experiment are outlined, and three photographs showing an
original hologram, its reproduction through the use of the computer, and its
reproduction by laser are obtained. The authors note that the whole reprodue-
tion procedureusing the computer takes about six hours of machine time on
the Kinsk-22.

"Pulse Noise Su.ppression in.a Televisicn~,Recd.iverll
Moscow, Tekhni-ka kino iJelevideniya,, No. 7, 1971, pp 55-57
Abstract: The noise dealt with in.this article originates either
in industrial appliances or in the receiver itselfi and is mani-
fested,as chaotic pulses of random amplitude and of the duration
of one scanning ulement. The aiithorslobtain an algorithm for the
filtration of the noise on the basis of the radicaldifference be-
tween the nature of the pulse,noise and of the image signal. This
algorithm is found by using the theory,of statistical solutions if
the a posteriori distribution of the.transmitted image and the
form of the function for the losses, conaected with the difference
betweea the transmitted and re
produced~images are kno,,,Nn. The dis-
tribution of the difference between'the,video signal for a given
element of the image and its value predicte 'd for the surrounding
'bution v
elements is taken as the a posteriori distr.1 alue. On the
basis of the obtained algorithm, a filtration system is worked out
and its block diagram given. It was.developed in 'ramsistorized
form, in 20 stages, and tested; the results of the test are shown
'in the form of contrasted photographs of televisi,on images with
and without the filter.
