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 'j,dPv c for acceleratlng*the transmission of dIscr.te pneumatic signals*,and a com- r d 11 -ACCESS*I ON NR-.

Aftera 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.

The search metb&-le involved In L 28750-65 ACCESSION NR: AT6003302 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 V WM!j tar 0-1 1--A are compl" -Ise level Leh h, the - __rhen the obaractertaticis of tM %M�, -ideru n"-, -difft-In Its -characteristics --the trial- perturb~t_10~r;U~7_ obj eat han W_ go - e a strang cause a elpificant deviation from optimum cot"d1tions and when the required trial Com IWIL L 28750-65 ACCESSION NR: AT5003302 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).

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.

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.

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 card 1/4 22457 S/186/60/002/001/020/v22 Preparation of silver-111 from neutron-irradiated....

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 Card 2/4 22457 S/186/60/002/001/020/022 Preparation of silver-Ill from neutron-irradiated....
