As the signal eing recirculated Is shifted along the frequency axis, its amplitude varies t khe irregularity of the real frequency characteristic. Simultaneously, the signal summation takes place; by selecting the shape of the frequency characteristic, a summation with a desirable weight function can be achieved. Formulas are derived which describe the connection between the frequency-characteristic shape and variations of signal amplitude with circulations. From these formulas, the effect of the characteristic irregularity upon the maximum permissible numbor of circulations is doduced. Orig. art. has, 2 figures and 10 formulas.

TITLEt Discrete Representation of a Time-limited Signal PERIODICALs Radiotekhnika, 1961, Vol. 16, No. 1, pp. 75 - 80 TEXTs Referring to studies of V. A. Yotalinikov and K. Shennon, the representation of a time-limited signal by a finite series is shown which, contrary to the Kotellnikov series, describes the signal by using discrete values within a time interval O-T. The author discusses topics like estimation of errors, spectroscopic analysis, and references to the Kotellnikov series. The series in question can be obtained directly from the Fourier series for a function (F(t) which is defined for a time inter V/ val O-T and vanishes identically outside this integral, if summation is discontinued at a finite value of the summation index. Denoting the frequency connected to this summation index by f v transforms the Fourier f T f T v v series J(t) a + sin n(jit + @.oos nc,),t making use of the sums 0 n Card 1/4 Discrete Representation of a Time-limited S/108/61/016/001/007/007 Signal B010/B077 1P z i k-1 )sin n ci t -11 2 t@j(t )con n ci t which correspond to n k @;f(tk 1 k9 @n _k 0 k 1 k the integral expressions for T n' In' where tk - ktAt (At is a time element of interval O-T) into a new series 2fvT sin 6) T(t - k4t) Ct) - :@:I(k&t) - 1 %-1) with wV . 2z fv , k - 2fvT + 1; 63 sin -1 (t - k&t) v X T the convergence properties correspond to that of a Fourier series. According to (5) it is possible to describe a function limited to the time interval O-T by 2f vT discrete function values of the basic time intervals. Fig.1 illustrates the approximation function of (5). A simple calculation is only necessary to show that (5) goes over into a Kotellnikov series if the interval T approaches infinity keepingto v fixed. The error of (5) is estimated by the method of Fourier series; here, the error is connected with the residual energy of the signal above the limit f v The author Card 2A 88 80 Discrete Representation of a Time-limited S@1108V611016100110071007 Signal B010/B077 concludes his paper by giving the spectroscopic separation of the signal represented by (5); he Bets (@(t) - ?(t)A(t) with A(t) - I within t'he interval O-T and L(t) - 0 outside of it; q(t) denotes the periodic function having a period T.

A055/A101 of the AGC filter and B 1 being the rigidity of the control. The au- thor plots the graphs of ;fa3and IV as functions of R ( a) for different fixed values of y (two sets of graphs are reproduced in the article). These sets of graphs permit plotting the frequency response of an amplifier with AGC for the case of any concrete AGC-filter [the R (92)-axis being replaced by the @2 -axis]. On the basis of the plotted graphs, the author analyzes the following problems: 1) AGC stability. 2) Operation of the AGC in pulse receivers (the case of simple RC-filters is examined in particular). 3) Transients: the author compares various filter-types in the AGC-circuit, giving the sam6 permissible phase distortions at a determined frequency (620, from the point of view of the setup time (the compared filter-types are the simple RC-filter, the filter of the second order with phase correction o(, = 0.24 and the double RC-filter rC 1 T2 = 242). 4) Demodulating properties of the AGC. In the last part of the ar- ticle, the author describes a method1br calculating the AGC, this calculation being divided into two independent parts: 1)Ensuring the required stability of the output level of the signal. 2) Calculation of the AGC filters that permit obtaining the required phase-frequency characteristic.

The superadded fuel fed to the accelerating engine must be strictly controlled; at ground level, the superadditions must not exceed the safe figures which, for early engines, are about 170 to 70 percent above normal. The fuel-air mixture, excessively rich in fuel, leads to faulty engine operation; the engine must then be stopped. At low speeds, the accelera- tion is controlled by the automatic pickup device (avtomat priyemistosti), and at high speeds by the Card 1/3 AdVUstment of Engines with Turbo Starters sov/86-58-10-27/4o hydraulic decelerator (gidrozamedlitell). The accelera- tion of the engine is delayed for a short time while- the automatic pickup device is being taken over by the hydraulic decelerator. The engine pickup is adjusted by tuning the automatic pickup device and the hydraulic decelerator. When the adjustment of the automatic - pickup device is changed, the acceleration of the en- gine changes only within the range from low speeds to 3,000 rpms, and when the tuniM of the hydraulic de- celerator is changed, the acceleration changes at speeds above the cruising value. Within the range from 3,000 rpms to the cruising rpms, the acceleration of the engine develops highest valuesand, practically, does not depend on the adjustment of the above devices. A substantial change in the tuning of the automatic pickup device may result either in an excessive supply of the super-added fuel or in an insufficient supply of fuel with ensuing difficulties In both cases. With the 'ailtomatic pickup device (at up to 3,000 rpms), the Card 2/3 Adjustment of Engines with Turbo Starters sov/86-58-10-27/4o 8-to-10 see. periods of acceleration are recommended in order to get the most favorable fuel superadditions. Some details on the adjustment and tuning are giverr. The reliability of the starting of turbojet engines on the ground depends also, to a large degree, on the a- mounts of the fuel superadditions.- Engines with high- power tarbo starters start relatively easily, except that some difficulties may occur in the spring or fall, but this can be remedied by taking adequate measures; details are given. The change in the fuel pressure be- fore the fuel nozzles, at about 300 rpms, affects the starting operation very greatly. The change in the adjustment of the automatic pick-up device affects the starting, too. If the automatic starter and automatic pickup devices are tuned to exceBBive or to too small fuel superadditions, unsatisfactory starting may re- sult. Three graphs.

TITLE: Vacuum Distillation of Metals with Condensation on a Heated Surface PERIODICAL: Fizika metallov i metallo,edeniye, 1959, Vol 7, Nr 6, pp 862-867 (USSR) ABSTRACT; The properties of heat-resisting alloys are influenced to a considerable extent by ;he purity of the starting materials. Vacuum distillati)n is a promising way of purifying such materials. Tie authors describe their use for purifying iron of th@ method developed in 1952 at the Fiziko-tekhnicheskiy nstitut ANUmSSR (Physico- technical Institute, Ac.Sc. *Tkrainian SSR) for vacuum distillation with condensation of the metal on a surface at a high temperature. The authors consider this more efficient than published methods and they have used it successfully for purifying beryllium (Ref 5). The distillation of the iron was effected in a working vessel (Fig 1) with evacuation by an oil diffusion pump (2500 litres/sec) and a type VN-2 backing pump. Card 1/4 0.5-3 litre alundum or beryllium-oxide crucibles wound 5@ T;" JiV5 @.A SOV/126-7-6-9/24 'Vacuum Distillation of Metals with Condensation on a Heated Surface with molybdenum or tungsten heating coils, contained the metal. The heated column directly over the crucible was generally lined with thin iron sheet, on which condensation occurred. The temperature of the column surface was chosen such that iron condensed while the impurities remained vaporized: the lower part up to 13000C, the upper to about 11000C. Assuming as a first approximation that the condensing metal and impurities form an ideal solid solution, the authors apply the Knudsen-Langmuir equation to calculate rates of evaporation. From a crucib Ie at about 1580*C evaporation of metal occurred at 1 g/cm hr., 75-80% of which was recovered at a column temperature of 1250-13000C. Tables 1-3 show compositions before and after distillation (single and double) of armco, electrolytic (single only) and carbonyl irons, respectively. Purification from Mn, Mg, Cu, S, P, N2 and 02 was good and somewhat less so from aluminium. Considerable contamination from Card 2/4 evaporation of crucible material was possible, but with double distillation the impurities could be reduced to SOV/126-7-6-9/24 Vacuum Distillation of Metals with Condensation on a Heated Surface 0.01%. The resistances of some long-needle single crystals of iron in the condensate were compared at OOC and at low temperatures in the laboratory of B.G.Lazarev, acting member of the Ac.Sc. UkrSSR: the ratio values agree fairly closely (Table 4) uith those of Itleysner (Ref 6) for the purest iron and indicate that the needles were 99.996% Fe. The authors have also studied the purification of high-carbon (7% C, 73% Mn) and medium-carbon ferromanganese. The same apparatus was used, evaporation temperatures being 1100-14000C. Rates of evaporation tended to fall through impoverishment of surface layers with manganese and formation of a graphite layer. Lower iron contents were obtained when baffles (Fig 2) were fitted in the column. On the lower baffles, kept at about 10000C, almost all iron condensed, the manganese condensing mainly on the middle baffles (750-8000C). Table 6 shows the composition of the condensate from the third and fourth baffles. A carbon content of under 5 x 10 3% is inferred. The purity of the manganese after a single Card 3/'1 distillation is over 99.96%.

TITLE: Temperature Dependence of Internal Friction and Elastic Constants of Pure Iron PERIODICAL: Fizika metallov i metallovedenlye, 1959, Vol 8, Nr 2, pp 249 - 254 (USSR) ABSTRACT: The authors point out that in investigations of the internal friction of iron (Refs 1, 2), the purity of the metal has been insufficient for studying the nature of the internal-friction peaks. For the present investigation the authors used iron vacuum-distilled by the vacuum-distillation method developed at the Fiziko-tekhnicheskiy institut AN UkrSSR (Physico- technical Institute of the Ac.Sc. Ukrainian SSR), in which iron vapour condenses on a surface heat&d to 1 200 - 1 300 0C and covered with 8ure-iron foil. Evaporation was effected at 1 600 C from alundum crucibles. The distilled iron, remelted in a high vacuum, was poured into 5-kg ingots (cast-iron moulds) from which 120 x 15 x 15 mm pieces were cut for shaping into test Cardl/4 sov/126-8-2-14/26 Temperature Dependence of Internal Friction and Elastic Constalts of Pure Iron pieces - 10 mm in diameter and 100 mm long.

The composition of the metal was: 0.00390' each C, 08; 0.00100 each S, P. Al; OM010.10 each N21 Mg; 0 - 0 070/0 Mn; 0.008-,.' Ni; 0.0006% Cu. The tests were carried out in vacuum in a resistance furnace (Figure 1); for the measuring circuit the system proposed by Tsobkallo and Chelnokov (Ref 5) was used and test-piece oscillation was produced by a self-oscillating system (V.A. Zhuravlev Ref 4). The relative deform@tion on the test-piece surface did Aot exceed 5 x 10 Figures 2 and 3 show internal friction as functions of temperature. Figure 2 refers to pure iron without (Curve 1) and with (Curve 2) a magnetic field of 100 oE. Curve I in Figure 3 refers to armco iron and Curve 2 to vacuum-distilled armco iron. Card 2/4 The internal-friction dependence on the temperature was sov/126-11-2-14/26 Temperature Dependence of Internal Friction and ElaL'stic Constants of Pure Iron found to be similar for 99.99910 iron as for other metals; but the absolute value over the whole temperature range is several times that for arinco iron and other metals. The high value for pure iron is due to losses in magneto- niechanical hysteresis arising in periodic deformation in the range of very small strains. The application of a magnetic field reduces the value greatly. The results showed that not all the carbon in the iron is in the form of solid solution. From the internal-friction measuring technique the dependence of the elastic constants on temperature were obtained (Figure 4)j for the moduli of normal elasticity and shear the relations are almost linear in character.

A compensating method with a PPTV-l potentiometer and M-21 galvanometer was used, current stabilization being secured at 1A with the aid of a barretter, The test pieces (Fig 1) of the type proposed by Kan and Lazarev (Ref 4) were in the form of 3 to 6 mm diameter and 50 to 100 mm long cylinders with slivers bent back at either end (for voltage tappings), The test-pieces were suspended in the hot zone of a special ceramic-less resistance furnace (Ref 5). This (Fig 2) had a system of horizontal spiral heaters supported by tungsten rods enclosed in a system of molybdenum-sheet cylinders. Its working space was 200 mm bY 35 mm in diameter, giving a temperature up to high . 2500 C at 6 W.

By using this method, the coefficient of heat conductivity was measured for a molybdenum rod in the temperature range 900 - 2200 0C. In a plot, p@ 189, the results obtained (Curve 2) are compared with those of other authors (Curves 1 and 3 - the latter based on results of Osborn, Ref 2).

The measured values of the electric resistance and of the heat conductivity of Mo for various temperatures are given in the table, p. 190, which also contains Wiedmann Franz ratios calculated from these values. In the temperature range under consideration, the obtained values of the ratio XJO/T are less than the theoretical ones and show little dependence on temperature, with a minimum in the tempera- ture range 14ooib 1600 OC.

Data on the temperature dependence of the thermal and elecArical canductivxty of tungsten and graphite are reported as well as the values of the Wiedemann-Franz ratio in a wide temperature interval,, Empirical formulae are put forward to represent the thermal conductivity of tungsten and graphite as a function of temperature. The thermal conductivity was determined by the method described in a previous paper (Ref. 5) and is based on the following considerations.

These quantities were measured with the aid of a special device. The specimens were placed in water- cooled holders, one of which was free to move when the specimen expanded so that no stresses were applied to the specimen. The distance between the holders could be varied between 0 -and 150 mm and the potential difference across defined sections of the specimen were measured by means of molybdenum or tungsten contacts. The whole system was placed in the vacuum chamber in a vertical position, the vacuum being of the order of 10-5 mm Hg. The potential differences were measured with the AC potentiometer P-0-:3 (R-56), while the temperature was measured by the optical pyrometer OnrV,V--
