Tashkentsk. tekstil'n. in-t, 1956, Nr 3, pp 110-115 ABSTRACT: The relationship of the hardness of coatings (HC) applied by production cathode sputtering equipment to the conditions of metallizing are investigated. It is found that HC depends upon the spraying conditions and the speed of the equipment. HC declines as speed rises. To obtain high HC with wire 2.4-2.5 mm in diameter the following metallizing procedure is recom- mended; 100 mm distance between nozzle and surface to be coated, 6 atm pressure, 28 volt potential, 210 amps current, Card 1/2 rate of spraying 1.46-1.65 m/min. It is recomm' ended that HC SOV/ 137-57-10-19803 . The Hardness of Steel Coatings (cont.) be measured on a Brinnell press, as measurement with the Rockwell tester . is too greatly influenced by the effect of the porosity of the coatings. Coat- ings of identical quality may be obtained both with large and small equip- ment when spray-coating procedures are adhered to. M. Z. Card 2/2 GALIPERIN, M.Ye.; SKRGEYEV, V.I.

The advantage of this circuit is that the t-,vo shafts are not loaded by the control action and this improves greatly the operation of the differentiating mechanism. The differential equation describing the behaviour of this dynamic system is Eq.(l), p.174. The sketch, Fig.2, shows a modified circuit, the behaviour of which is expressed by the differential equation, Eq.(2), Card 112 p.174. The accuracy of the differentiating mechanisms can 24-11-2AW/~31 Certain comparative characteristics of the accuracy of differential friction mechanisms. be improved by feeding into the armature of the servo-:notor a voltage complying with a relation specified in the paper and for -this case the relations governing the functioning of this circuit can be expressed by the differential equations, Eqk3~ p.174. In this paper a comparative analysis is made of th-- operation of these three differentiating mechanisms. The carried out calculations show that for a characteristic regime, for the variant shovrn in Fig.3, the speed of damping of the transient process is four times as high as for that shown in . Fig.1 and three times as high as for that shown in Fig.2. Simultaneous utilisation of the derived relations, Eqs.(5a), (5b), (6a), (6b) and (7) and the relations plotted in Fig.4 permit qualitative investigation of the relative accuracy of the operation of various Circuits of automatic friction mechanisms even in the drawing board stage of the design. TheA~e are 4 figures and 4 references, all of which are Slavic. SUBMITTED: April 6. 1957. AVAILABLE: Library of Congress. Card 2/2 SERGR-EV, W-I. V, J , W. J.

The following system is discussed and it is assumed that it contains a non-linear link with single-valued characteristics consisting of straight-line segments. As typical examples are chosen,firstly, a link with a zone of insensitivity (Figure 2) and, secondly, a link with a zone of saturation (Figure 3). Both these non-linearities are included in the characteristics of the electric motor. The analysis of the second case, described very briefly, follows closely that of the first case which is discussed in more detail, An expression for the non-linear link is substituted into the moment equation for the electric motor, From this Card 1/3 equation and that for the armature the characteristic SOV/24-58-7-14/36 On One IiIethod of Calculatins the AraDlitude of Self-excited OS(..,4 .L11ations equa-[~ion for the system is derived, From the characteristic eqUation zrai al'Uernabive expression for the non-linear link is ol)talned, By equatin- the two expressions, Bq (12) is ob'u-ained in which the right-hand side contains only the -oarameters of the system.

The system consists of 2 axes, I and 2,, an amplifier, 3 , a DO motor with independent excit-- ation 4 , -the reducing ear 5 . A nonlinear characteris- tic of I;Iie motor is shown also in Fig.l. The dynamic equat- ion of the linear part of the system is expressed by Eqs.(l) and (2), where T 1 fand T2 - mechanical and electromagnetic constants of time respecti ely, k1, k 21 k 3 - constant coefficients, I - electric power of rotor circuit, a(t) - slowly varying external action. The ortho-vibration may oc.,-,ur when the characteristic eauation (Ba.(3)) corresponding to Eqs.(l) and (2) does not satisfy a condition of stability (bard 1/4 (a - amplitude of ortho-vibration.
