The p inciple itself of constructing systems reacting to particular derivatives of the desired func-" tjZn with respect to coordinates of the reacting elements is not now, but the method discussed, which was first used In the Electrical E ineerinz Institute, Leningrad (Institut elektromekh&-4~' niki) rose In connection with designing a system of programmed control of metalworking mg- % chines, first to reproduce plane curves and then curves lying in a given surface, and made it Card 1/2 -~,--KT6016442 possible.not only.to inaicateth~'general methods of synthesis of digital differential analyzers for reprod~cirq dMerent types of multidimensional curves, but also to show a very general method of dosiping ~, 6earch sistem for multivariable function exhama. The method also finds extrarna at the J~teroe6tion of multidimensional surfaces.

The quality of the ceramic shell obtained by -hydrolysis with different water consumption was investigated with the use of commercial sthylsilioate (S02 .- 31.3%;HC1-0 .2~) Five variants of hydrolynis were carried out and the quality of the ceramic shell was determined by various factors such &at mechanical properties, rate of hydrolysis and syneresis, and crack formation after calcination. It was stated that optimum strength of the shell was obtained by the combined effect of hydrolysis, syniresis and the eliaination of water bound by the Card 1/2 gel. The stren:th of the shell increased with a higher water SOY/148-59-2-16/24 The Problem of Ethylailicate Hydrolysis in Smelted-Form Casting consumption. Banding strength and deflection are characteristic of the plastic properties of the shell which depend on the water consumption in the gel. Crack formation is inveraly proportional to the shell strength. The tests proved that maximum strength. and plasticity and minimum cracking of the shell were obtai'ned~ by ethylsiliosts hydroly Isis, producing gal of dimetasilicia"acid (H23'205 or S102;O-5 H20).

The permissible magnitude of residual stresses in welded units and machines has as yet not been established. Therefore the gathering of experimental data obtained from specimens and natural welded structures is of considerable importance. For this purpose an inventiga- tion was made by the authors and Yu.N. Zaytsev, G.I.. Shevlyakov, V.A. Ignat'yev, and P.V. Novichkov. Tests were performed with 120 kg specimens welded from 60 mm thick steel. Reactive stress fields were obtained by welding-on cormer plat- es. Residual stresses in the built~.up metal, the heat-affected zone and the bass metal were determined by the diffraotion-roentgenographical method. Vibration of specimens as a means of reducing residual stresses was for the first time checked in the Soviet Union, yielding satisfactory results. Moreover,residual Card 113 26020 S/1~5/61/000/008/Dlo/tll On the expediency ... A006IA101 stresses were directly determined on welded press frames, manufactured at the Voronezh Plant of Heavy Mechanical Presses without heat treatment of the welded structures. X274A and X862 frames were subjected to welding, heat treatment, and vibration; stresses from useful loads were determined. The weld-Joints were subjected to ultrasonic control with the aid of flaw detector ~3A -714 (UZD-7N) The distribution of residual stresses was studied by the tensometrical method with or without partial trepanation of the frames. Standard pickups of 25 mm base, 120 ohm resistance and a coefficient of sensitivity K - 2.1 were glued on both the internal and external sides of the frames in order to estimate-approxi- mately the bending stresses determining the deformation of the frame. The de- formation of the pickups was measured with an automatic electronic ?WX -3 (EID-3) device. The experiments performed showed that heat or other treatment of welded frames was not expedient. This conclusion is confirmed by the results or analyz- ing the operation of welded frames which were not heat treated, namely: 1) cra:ks and other defects caused by residual stresses were not observed in welded press frames and shears, operating over 4 - 5 years; 2) the accuracy of the presses Is satisfactory; losses in motor power during idle run are low; 3) the fatigue strength of frames in complex-strained state in the presence of stress concentra- Card 2/.3 On the expediency ... 26020 S/I 1611000100810101011 AOOP/AIO1 A tors such as poor fusion, is satisfactory.

TITLE: Differential Counters for X-Rays and Their Use (Differentsiall- nyye schetchiki rentgenovskikh luchoy i ikh primeneniye) PERIODICAL: Zavodskaya Lab oratoriyal 1959, Vol 25, Nr 39 PP 369-372 (USSR) ABSTRACT: This paper was read at the Hauobno-tekhnicheskoye soveshchaniya po primeneniyu renigenovokikh luchey k issledovaniyu materialov (Scient if ic -technical Conference on the Application of X-Rays in Material Checking) hold in Leningrad in 1958. Differential counters were deeigned which can be used for precision measure- ments of the changes in crystal lattices for X-ray structural and X-ray spectrum analyses. The differential counter with fixed emitter may be manufactured of two Geiger counters or of two proportional counting tubes separated by a wedge tFig 1). The wedge serves not only as a partition between the couAting tubes, but also as the photo-electron emitter of absorbed X-rays. An experimental investigation of the setup of the differential counter as to aluminum emission li~ss resulted in a mean aquare error of approximately 0 .001 in angles 9. The investi- Card 1/2 gationa were carried out by means of a goniometer of the URS-50-1 .Differential Counters for X-Rays and Their Use SOV/32-25-3-49/62 unit. An automatic setup was developed for the differential counter by which it is made possible to follow shifts of the diffraction line which may occur due to certain factors (asi e.g. temperature) (Fig 2). The diagram of an automatic record- ing of the parameter changes of the crystal lattice (line shift) of angle 0 is given for the line Kal Cu(333) of aluminum'as a function of a steady temperature change (Fig 3), Besides the above apparatus a circular differential counter (Fig 4) as well as a differential counter with a movable diaphragm (Fig 5) were suggested. An application of the pattern described renders possible the manufacture of an apparatus for the con- tinuous analysis of solutions and for an automatic control of production processes. A diagram obtained during a quantitative X-ray spectrum analysis of copper in a copper sulphate qolu- tion is given (Fig 6). There are 6 figures and 2 referengesp 1 of which is Soviet.

Four thermal effects were observed on the beating curves of alloys containing from 25 to 51 wt, % Bb: the first (a small endothermic effect) could not be identified; the second (exothermic) corresponds to the conversion Cd4Sb3 3CdSb + Cd; the third (298C) was due to the fusion of the cadmium eutectic; the fourth (438C) was the fusion of CdSb. Zone melting was found to be the most suitable method for preparing Cd4Sb3 single crystals.

ANALYSIS AND EVALUATION: The book is Intended as a textbook on television for communi- cations technical schools where television is taught as part of a more general course "Television and Photo-Communications" and is approved by the Ministry of Communications of the USSR for use as a textbook. The approach is largely descriptive, with little mathematical and electrical analysis. In its general plan, the book seems to follow rather closely the work of Kenneth Fowler and Harold B. Lippert (both of General Electric) Television Fundamentals Theorl, Circuits and Serv- icing, McGraw-Hill 763R-Co., first publianea in 1945. While the reviewed book is much less detailed, it does give some information on Russian and particularly Soviet achievements in this field. 1/6 IGNATIYEV, N. K., Televidenlye A Irl 3,3NF3 (Suvercedes A Chapter I. Physical Fundamentals of Televisiono pp. 6-27. The basic properties or r1ght and the light a cteristics of televised objects are described. The physiology of vision is explained and the basic conceptions of the photoeffect, internal and external, and some photoelectric instruments are described. Works of A. 0. Stoletov (1888, P. 15) in this field are mentioned. Mechanical and electronic television are explained. A description of a method of mechanical scanning (based on progressive scanning) invented in 1884 by P. Nipkov (pp 21-22) Is given. In 1907 B. L. Rozing suggested cathode-ray scanning (p. 23, 25) and in 1931-32 S. L Katayev developed a cathode-ray transmitting tube called "ionoscopen which is described (pp. 25-26). The first high quality TV transmissions in the 'USSR were started in 1937 when an ultrashort-wave transmitting center was put in operation in Moscow. The Image was scanned into 343 lines, or low clear- ness. In 1948 the Moscow TV center started to scan into 625 lines, which, according to the authorj is the highest clear- ness in the world. [The number of frames transmitted per second in the USSR Is 25. Thus the line frequency is 625 x 25 = 15,625 compared with the US standard of 525 x 30 = 15,7501. 2/6 IGNATIYEV, N. K., Televideniye AID 780 - M Chapter II. Cathode-Ray Tubes, pp. 28-77. The chapter gives a description of the eleaFr-omagnetic and electrostatic types of cathode-ray tubes and also of the special types of tubes where the beam is focused by electrostatic means and deflected by electromagnetic means. Elements common to all types are discussed. The author explains the movement of electrons in the electric and magnetic fields by introducing simple equations. He describes the electron focusing and deflecting systems used and explains the role of secondary electron emission in the performance of TV tubes. S. I. Katayev (P. 56) and L. A. Kubetskiy (P. 57) contributed much in secondary electron emission. The picture tube with various types of fluorescent screens is described, as well as certain of the most common defects like the halo and ion spot and means for their prevention. A description of the television camera follows: the iconoscope, its functioning and deficiencies, its modifications as developed by L. A. Kubetskiy (P. 70-71), S. I. Katayev (P. 71)j P. V. Shmakov and P. V. Timofeyev (P. 71)o the orthicon, and the orthicon with the electron multiplier and the image transfer. 3A IGNATIYEV, N. K., Televideniye AID 780 - M Chapter III. Television Signals and Their Transmission,, P. 78-123. Ba-sic requirements for television picture are described and the scanning process is explained. The full television signal and its components: line and field syn- chronizing pulses, horizontal and vertical blanking signals, and equalizing pulses, are described as well as the general requirements for the television transmission path. Expla- nations are given of signal- to-interference ratio and various kinds of noises; the pick-up tube sensitivity and minimum brightness (threshold of sensitivity), video i-f amplifiers: compensated one- or two-stage resistance-coupled amplifiers, low-frequency and high-frequency compensation, and noise limiters of the AFC-type (automatic frequency control of the horizontal sweep generator). The transmitter plant equipment: the studio, control room and transmitting terminal, is described in conclusion. Chapter IV. Reception of Television Sivals, pp. 124-150- The over-all operation or the receiver is explained step by- step with the help of a block-diagram. The r-f and i-f cir- cuits and in turn the video and sound carriers, the video channel's clipper stage, the synchronizing pulses, horizontal 4/6 IGNATIYHVj W. K., Televideniye AID 780 - M and vertical deflection circuits with their sweep generators and the speaker and the picture tube are described. Chnpter V. Television Scanning, p. 151-179. Sync and scanning as used In television receivers are described, but the more complex schemes of sync and scanning of the picture signal are not given. The chapter explains the scanning methods and the operation of the various circuit elements: saw-tooth oscil- lators or sweep generators, three types of which are described (the gas-tube oscillator, the blocking oscillator, and the multivibrator), deflection circuits (electrostatic and electromagnetic), transient oscillations and RC damping cir- cuits., synchronization and generators of saw-tooth current. The chapter ends with a brief enumeration of high-voltage power supply systems. Chapter VI. Basic Problems of Modern Television, p. 18o-197. The author discusses the outsta-nUTn-g problems of modern television: 1) extension of the range of TV reception and studies In this field by S. I.

TITLE Basic Properties and Characteristics of Synchronous Filters. PERIODICAL Radiotechnika U, faso. 9, 59-71 (1956) Issued: 19.1;.1956 A considerable number of devices for dividing complicated oscillations into two components, viz. synchronous and asynchronous components, have already been described in literature. The present work investigates the operation of all these devices for the special purpose of constructing the so-called synchro- nous filter, which is the natural generalized form of the resonance filter. Unlike the latter the synchronous filter is able to eliminate or absorb oscil- lations of any form which are repeated with a given frequency f 0 to which it is"tuned". The basic and integral component of a synchronous filter is the "memory" which must "remember" the shape of the oscillations encountered. Here the ideal wiring circuit of a synchronous filter with a capacity storage device is used. The basic parameters of a synchronous filter are the op ration f 0 and the extinction coefficient b. These parameters fully characteris: the filter's influence on the shape of the input voltage. Owing to the fact that on the occasion of the operation the potential of the connected capacities changes several times, the shape of the voltage transferred from the "memory" is lizagged" ( ). Analysis of the operation of the filter began with the setting up of an initial formula which expresses the relation between Input- and output voltager By means of this initial formula it is possible to solve Radiotechnika, L1, fasc- 9, 59-71 (1956)' CARD 2 / 2 PA - 1528 all tasks, i.e. such with a stable and such with transition character. The formula is then used for-the investigation of the influence exercised by some shapes of the input voltage on the synchronous filter. This is done firstly because these shapes are of great practical interest, and secondly because hereby the characteristics and the properties of the filter are best deter- mined. These shapes include: the periodic voltage of an arbitrary shape, the harmonic voltage, and the noiai voltage. These various forms of input voltage are then investigated. In the case of the last of these forms, the ability of the integrating filter of diminishing noise voltage is described as "filtration coefficient", and the relation between the latter and the parameters of the filter is set up in form of an equation. The question is then investigated by what equivalent resistance the capacity "memory" can be replaced in the circuit of the synchronous filter. It was found that for this purpose a drawn-out line may be used, which is all the more natural, because a line has the peculiar property of having a "memory". In principle any other device able to "remember" the shapes of the oscillations encountered can be used.

N-dimensional in- formation (for example, moving or stationary pictures) must be preliminarily scanned for transmitting and is thEreby converted to one-dimensional information. The priim,ipal statistic characteristics of information are the correlation function and the energy spectrum which are generalized by the author for the case of n-dimensional information.

He arrives at the conclusion that the application of n-dimension- al statistic characteristics of information may sim- plify the solution of a number of problems, because the n-dimenslonal staiistic characteristics are much simpler than one-dimensional functions of the same information after scanning. The relation established in this way permit a transition from spatial statis- tic characteristics to spectral characteristics and vice versa. There is I Soviet reference.

The essentially now feature in the present article is the use of correlation between the brightness elements of the transmitted image to give quantitative information and also to take account of distortion due to movement of the transmitted object. The associated shortcomings of a television picture due to a finite scanning spot size and aperture distortion are neglected. The position of the scanning spot relative to its position at a slightly differant, instant can be represented by a three-dimensional corralation function D. The appearance of the seaming raster is shown in Fig 1 with the separate time dependences of x and y szans in Fig 2. Fig 3 is a diagram showing the relative duration of stay of two points at various distances from one another in the x-axis direction. Eq (1) is a Card 1/4 description of the scan process in terms of point-to- point displacements and time intGrvals, instead of point BOV/106-59-1-3/12 The Energy Spectrum of a Television Signal position and time. A transformed version of the correlation function using these particular variables is given in (3). This expression may be thought of as referring to a virtual scanning system as shown in Fig 41 where point-to-point displacements are plotted instead of actual distances. Eq (5) Is an analytical expression for the energy spectrum and can be obtained as a Fourier transform of the one-dimensional correlation function Bl('r) in (3). That case of the greatest interest is the one where the three-dimensional correlation function can be expressed in the form of a,product of three one- dimensional functions as in (6). This is shown in more detail in (7) and (8). It is possible to show (see Appendix 1) that the overall energy spectrum may be expressed through the separate enor&y spectra by means of a two-fold correlation integral (10). Since the separated one-dimensional correlation functions for the two dimensions of the scan are periodic, then their energy spectrum can only be expressed in terms of delta functions The three separate frequency trans- Card 2/4 (see Appendix 2). formg are (11), (13) and (15) and they are combined in a SOV106-59-1-3/12 The Energy Spectrum of a Television Signal two-fold convolution (see Appendix 3) giving a final expression (16). Two cases of this latter expression should be noted: when the number of lines z is odd, the scan is repetitive; and when z is even, the scan is progressive. The space and time correlation functions of a television image have been studied b a number of authors, in particular Kretzmer (Ref 2T. If the appro- priate functions are approximated by Gaussian curves, Figs 5a and 5b show the energy spectrum for repeated and progressive scans respectively for the case where the number of lines is z = 5. Detailing in the image along the direction of the scanning line is deteruined by the overall extent of the spectrum. The amount of picture detail at right angles to this dtrection is determined by the amount of the spectrum which grcups itself around the harmonies of line frequency. The crowding of the spectrum around harmonics of the same frequency is a Card 3/4 measure of the speed with which the image can change. Finally, brief mention is made of the distortion effects SOV/106-59-1-3/12 The Energy Spectrum of a Television Signal which attend the interaction of spectra giving rise to moir6 effect and stroboscopic effect.

TITLE: Methods of Reducing the Spectrum of a Television Signal PERIODICAL: Elektrozvyaz19 1959, Nr 81 Pp 14 - 23 (USSR) ABSTRACT: This is a short review of bandwidth compression methods, as described in the technical literature. The methods are classified on the basis or their action and can be divided into two basic groups: 1) Methods in which the statistical properties of the signal are not considered and in which the frequency band is exchanged - a) for time or b) for signal power. 2) Methods which use the statistical properties of tho television image considered as a function of three variables (two space co-ordinates and one time co-ordinate). The statistical methods can be also divided into two sub- groups: A) without signal "discretization", in which the continuous nature of the signal Is maintained by the "free" parts of the spectrum are filled upi B) witti discreti- zation, in which only separate di3crete values of the Cardl/5 signal are transmitted. 05370 sov/lo6-59-8-2/14~ Methods of Reducing the Spectrum of a Television Signal The clanaitiation fichowe in shown in Figure 1, Under each sub-group are listed the methods which enter into that particular sub-group. Methods, which for some reason or other, cannot be included in the classification, are placed in the group marked "others". Not all the methods have the same value from scientific or practical points of view. These methods are then donsidered individually in more detail. In the frequency-tIme exchange method, the initial signal is "accumulated" and then transmitted at a lower tat** At the receiver the process in reversed and the initial signal recovered. This method reduces the bandwidth to the same degree as the transmission time is increased but has not found practical application due to undesirable increase in the transmission time, and difficulties in realizing the flaccumulatlon". In a television signal there in, however, some free time, i.9. timeintervals occupied by synchronizing and suppression pulses, alld by using this time, it is possible to reduce Card2/5 the bandwidth approximately 20%. 05370 sov/io6-59-8-2/12 Methods of Reducing the Spectrum of a Tel-evision Signal- In thA.frequency-power exchange method, a large degree of frequency bandwidth compression can theoretically be obtained but to obtain a permissible error in the presence of interference, a large number of power levels are required and the total power in so large that the method has not found practical application. The statistical methods without diberetization, in which the free parts of the spectrum are filledt are classified as statistical, since the law of the distribution of energy in the spectrum is a statistical parameter of the television signal. The television signal spectrum is then considered and a part of it (for progressive scan of a stationary image) is as shown in Figure 2a. When a moving image is transmitted, the discrete components of the spectrum merge into a frequency band. Two methods for using these free parts are considered: 1) the method of "alternate-11ne" scanning and 2) the method of "alternate-PoInt" scanning. Interlacing of the lines and of the points of the raster correspond to particular interlacing of the frequency Card3/5 spectrum. 05370 sov/io6-59,8-2/12 Methods of Reducing the Spectrum of a Television ignal Finally, uder statistical methods without dIscretization, we considered interchannel, spectrum-filling methods in whicti.two or more transmitters work on the one and same frequency channel. The general principle underlying the statistical methods of spectrum compression with discrati- zation of the signal Is as follows: the continuous information is divided into discrete values which are then tr-n formed Into a code. In the discretionizatIon process analysis to made of sections of the message, and from all of its possible discrete combinations only the most probable are transmitted by some code. The code capacity is calculated for transmission of these message combinations only. Signal compression Is obtained by reducing the number of discrete message combinations to a minimum. Thus, all the methods of this group are different forms of signal combinations In which the statistical features are taken into account to some degree. The variations considered are; 1) coding of the difference signal; Card4/5 2) transmission of the coordinates of new values; 05370 sov/io6-;?-8-2/jZ Methods of Reducing the Spectrum of a Television gnal 3) two-speed scanning.

PERIODICAL: Elektrosvyaz', no. 2, 1960, 71 - 72 TEM The author describes a simple method for analyzing the conversion of continuous communication into a sequence of discrete of time-separated send- ings. This method.is essentially a spectrum method. The "timo-separation pro- cess" (protsess diskretizataii") of signal f, (t), in the presence of filters at the input and at the output of the system, can be expressed as! CID f2 (t) S S f 1 (.0 g, (X -T) dTD (x),x ~2 (t - x) dtdx, (1) W where f (t) is the resulting signal, g (t) is the input filter transfer functic7n and D(x3 is the "time-separating" ("Usiretiziruyushchaya") function: D (x) - T Y, 8 (x - k T), K (2) Card 1/4 26207 S/106/60/000/002/608/009 Rendering discrete the signals with unlimited spectrum A055/A133 where 8 W is a delta-funotion and T is the "tinie-sep&ration" interval. Function D'(x) transforms, as a result of multiplication, the continuous function of the variable x. into a pulse function of the same variable, different from 0 only for x = kT. After a Fourier transformation of (1), the author obtains: 5 a, ((j - m 2E X. kl ( co - m Lt )k (3) 2 T T 2 where s, N) I s2 (w), k, (to) and k2 (w) are Fourier transformations for functions fl M, f2 W, 91 M and g2 M respectively.

Figure la ex- plains the formation process of the resulting spectrum, without taking Into ac- count the filter action. It shows that distortions of the initiil spectrum $1 M are due to the appearance of additional components, absent in the initial spectrum. To eliminate these components, the spectra of the initial and the re- sulting signal must obviously be limited byfrequency jwj -9r.
