ABSTRACT: The author describes a device developed at the NIlTeplopribor In Moscow
largely on~the basis of elements of the universal system developed at the Instit ut
avtomatiki I telemekhaniki (institute of Automation and Telemeithanics), and Intend-,
ed for use In the petroleumi gas, chemical, metallurgical and food processing In-
dustries. The principle of operation of the device Is that of combinative selec-
tions. This principle provides a high speed response'since It requires only one
communication channel to transmit any one signal, which Is particularly Important
for devices with pneumatic communication channels.- Binary and binary-decimal codes~
are useds The author describes the coding and decoding mechanlsma,as well as a

ABSTRACT: This Is a tutorial article on

brief definItInn of both of these classes of autb-m-allic search systems, the author discusses
at length an Important subclass called the systems of automaLic optimIzatlon. A general
optimization system consistB of a controlled object (or procesq) with n inputs (x,, - - - Xn),
a noise Input z and J outputs (y1,..., y ), a computer (or calculator) C and an afhomatlic
optimizer A, as shown in Figure I of il Enclosure. From the output variables y the
computer C computes the qua4ty factor Q, subject to the condition that some pre-

evaluation of the location of the dxtromum, all based on trial perturbations of the input
variables by the opUmizer, are: blind search, which can be deterministic (fixed scan
program), random or locally random, and search with analysis of intermediate results.
Ile applications of blind search are limited. The three main methods of search with
analysis of intermediate results are the Gauss-Zeldel method, the method of steepest
descent (slope) and the gradient method. no search methods are Illustrated by coii-
sidering specific systems described in the literature. Two of the simplest types of
optimizer were described by L. N. Fitsner (Elektrichestvo, 1960, No. 8, 61-67). These
are types lA01- 2 and JA01- 1, the last of which involves an integrator in the Q path Ind
can thu3 be used to control processes with high noise levels. The steepest descent
system takes a triwl -.-W4 x-In each of the Input variables and evaluates the corresponding
value of 9 Q. ~ From this data the gradient of Q la computed and then the optimizer A
takes large "working" steps Ax in the direction opposite to the direction of the gradient
vector until the sign of 4 Q changes, indicating that the minimum was passed. Then the
process Ile reversed. The gradient method Is essentially the same except that In this
method the gradient of Q Is evaluated after each working step so that the control becomes
much more accurate. Practical difficulties with automatic optimizers are encountered

perturbations must be large. Some of these ddficulties may be circumvented by cvalua-
ting all required data on a high speed electronic model ~#-f the object. This Is turn requires
a detailed knowledge or the-object and precludes the possibility of any unexpected
random changes In its characteristics. When two modeis are used, one slow and one high
speed, In such a way that the output of the slow model can be continuously compared with
the output of the actual object and the required data computed by the fast model, the
performance can be significantly Improved. The multichannel optimizers are often used
in automatic synthesis problems. Other types of automatic search machines may not
involve an optimization process. Examples are the Pandemonium (Programmed on
133M-704), the homecatat of Ashby and the machine for proving theorems in Euclidian
geometry., described by Gelerter and Rochester PM JRD, Oct. 1958). Orig. art.

ABSTRACT: The modular principle in pre s3ure -automation was Introduced by T. K.
Berends et al. (Priborostrayeniye, no. 11, 1963), and was further developed at the
Scientific Research Institute Teplopribor, where the following new pneumatic elements
have been experinentally produced and tested: 1) four elements for performing OR,
AND, NOT, and YES logic functions; 2) control mechanisms (pneumatic push buttons
YES and NO, pneumatic tumbler, terminal switch); 3) discrete pneumoelectric and
electropneumatic converters. All four logic elements are assembled from a set of
eleven standardized parts which Include nine plastic parts and two rubber dine. The
pneumoelectric converter is of the PlPR2 type; it converts discrete pneumatic signals
"0" and 11111 into discrete electric signals 0 and .0.25 amp/30v d-c, or 0 and
15 amp/115V a-c with up to 400 cps. 7he PlPhl-type electropneumatic converter con-
verts discrete electric signals "0" and 'T' equal to 0 and 60 mamp/24v d-c into
pneumatic- signals 0 and 1.4 kg/cm2 (t10%) pressure, respectively. Experiments proved

SOURCE: AN SSSR. Izvestiya. Tekhnicheskaya kibernetika, no. 3, 1966, 107-110
TOPIC TAGS: probability automaton, relial-ility theory, probability, finite automatonj

ABSTRACT: In this paper, which is a continuation of two previous articles by the
author (Izv. AN SSSR. Tekhnicheskaya kibernetika, 1964, no. 6, and Izv. AN SSSR.
Teknicheskaya kibernetika, 1965, no. 5), methods are outlined for finding the matriceg
Q, P (Xh), and R for any probability automaton with structural circuitry correctly
built on binary elements and containing feedback. The matrices, which completely
define the operation of these automatons (through analogous matrices of elementary
automaton components), are described. Automatons with 2 or more states are considered
The procedure described In the paper for finding flow and output matrices remains
valid even when the memory part of the automaton consists of several stages. The
results achieved in the study are applicable to the analysis and synthesis of probc-
bility automatons with components which are subject to failure. In conclusion, the
author wishes to express his gratitude to-B.---R. Levin for his commentary on the re-

TITLEt Preparation of silver-111 from neutron-irradiated palladium
PERIODICAM Radiokhimiya, v. 2, no. 1, 1960, 120 - 126
TEXT: A method was developed for the separation of Ag"' from neutron-ir-
radiated palladium by Isotopic excharge with AgCl,greelpitate. The Irradiated
Pd can be used after separation from silver as Pd 3 or Irradiated for a second
time to obtain A9111. With Its shorter half-life and low yield In gamma-radi
tion OvO) of relatively low energy,48.24 and 0.34 Mev) Agill is more conivenl:n-t
for medical purposes than P32 cr Au . In the present study two methods, which
have been described in literature, were employedt the.method of precipitating an
AgC1 carrier from solutions of irradiated palladium [Re'f. 2: F. Silicio et al.,
Anal. Chem., 28, 3, 365 (1956)], and the extraction of Ag111 from solutions of
Irradiated palladium by isotope exchange with already precipitated inactive AgCl
[Ref- 3S W.W. Meinka and D.N. Sunderman, B'clence, 121, 777 (195 ?h Nucleonics,
13, 12, 58 (1955)1- Optimum conditions for the separation of Ag by co-preolp-
itation with AgCl were determined, the degree of extraction and the radlochemical

purity of the product were estimated. Optimum concentration of HCl is I N and at
least 0.1 mg of carrier must be used. Heating the solution to 95 - 1000C effects
formation of macroorystalline precipitates. The AgCl precipitate containing
Agiii was re-preoipitated 3 - 4 times. Extraction degrees were tabulated. The
effect of BN03 concentration on the extraction degree of Ag111 was Investigated
in experiments with isotopic exchange and It was observed that concentrations of
HN%used in aqua regia do not interfere with the extraction, and reVI.tS obtaim.1
by e isotopic exchange method are tabulated. The gamma-spectrum of the prod-
uots obtained by the two methods was investigated with a scintillation counter
containlng a INY-2
1? (FEU-29) photomultiplier and a NaJ(Tl) crystal. The impurity
present in the A91 1 sample obtained by co-precipitation can be seen from the
maxina (45o, 66o - 89o and 1,340 kev) in the gamma-spectrum (Fig. 3). The same
Impurity, I.e., a lont lived Isotope with a half-life of more than 200 days wae
determined in the AgI 1 product prepared by isotopic exchange and was Identified
as Ag11O. In both prociucts Ag11O is present In an amount of about 0.05%. It Is
supposed that Ag11O Is formed from silver Impurities present In the original pal-
ladlum, or as product of secondary nuclear reactions. Since the isotopic ex-
change method Is simpler, more efficient than co-precipitation, and since the
same piirity of the product is observed in both methods, the following preparation

TEXT. The object of the work was to investigate the formation*of
'-'Complexes of microquantities of yttrium. The method of
investigation was based on changes In the co,~fficient of
distribution of an easily extractable c.(~lwnlcx with known stability

extractable complexes, into the As an amxiliary ayitem,.
~;'4the authors chose complexes of yttritim with 8-oxyquinoline (oxin),
...Which is of interest by itself as there are no data available on
f;~this system in the literature. The present pnjior describes the
first part of the work - a study of oxinate complexes of yttrium,
The measurement of the coefficierit,-3 of' distribution of yttrium
~i~oxinate was done in a perchlorate solution with the ionic force
