TITLE: Remote control of motion-picture cameras PERIODICALs Tekhnika kino i televideniya, no. 8, 1961, 30-38 TEXTs The authors review basic requirements for the design of remote-contiol systems for motion-picture cameras and describe the remote-control units de- signed by the Lenfillm studio. This studio has been developing remote-con- trol equipment for motion picture cameras for several years. The first scenes shot with the aid of remote-controlled cameras were filmed in 196o. Engineers I. Blutskiyp E. Drukh, and A. Pliner of the Technical Department, and'engineers A. Alekseyev and L. Dukhon of the Exposure Technique Depart- ment have actively participated in the development program directed by engi- neer L. G. Gol'shteyn. The basic desi6,m requirements for the camera remote- control system are: (1) switching off and on of the camera motor; (2) visual monitoring of the photographed picture; (3) anning and camera tilt control within a wide range of angles and speeds; (45 lens focusing control; (5) lens aperture control;, and (6) film footage control. Moreover, the Temote-control Card 113 B/187/61/000/008/002/002 Remote control of motion-picture cameras D053/D113 unit should be of light weight, easily transported and serviced, and contain the maximum possible number 6f standard parts. Three versions of remote- control units have been designed for (1) the "Ekler-studioll synchronous motion- icture camera; (2) the -Askania" motion-picture camera; and (3) the I--- KCP MOR) "Konvas-Avtomat" light motion-picture camera. The visual monitoring of the photographed picture is obtained with the use of a PT')/-OMi (PTU-0MI) industrial closed TV unit. The video receiver of this unit con- +aining a 35JIK26 (35LK2B) tube is mounted on the control stand while the cam-era tube, an 01423 (L123) vidicon, is mounted together with the motion- picture camera on the panoramic and tilting head. This head is driven by HA -501. (ND-501) synchro generators and HC -501 (NS-501) synchro repeaters; the lens and diaphragm are driven by HA -404 (ND-404) synchro generators and HC-404 (NS-404) synchro repeaters. For the"'Ekler-studio" motion-picture camera, an industrial 12 WC(12ShS) cradle head was used. The camera unit can also be mounted on a special light crane with a 9 m. jib, designed by V. Baranikov. The control stand can be dismounted, and it containsq apart from the video monitor, switches for the camera motors, synchros, and film foot- age counters. These counters are driven by CA-2 (SD-2) synchronous motors, The 1-KSIR motion-picture camera can be synchronized by using a special C., -ni ~~ /A S/187/61/000/008/002/002 Remote control of motion-picture cameras DOWD113 system with a r-31 (G-31) synchronous motor. This system was proposad by the film operator 0. Kukhovarenko and engineer A. AlekS-ir-,r. The entire remote-control unit is supplied from a 220 V industrial power network, or from the KX (KES) field po-wer plant. The remote control of the motion- picture camera enables filming to be carried out in difficultly accessible places, eliminates acting hazards, and facilitates the training of film p-ro- ducers. It can also be used for shooting scenes from an airplaneq in which case the panoramic head with cameras is suspended under the wing and the f~ontrol stand placed in the cabin of the airplane.

The modificativn oi the lattice spacing in the case of a diamond causes the double scattering in the X-ray picture to vanish. In order to find out whether this vanishing is of permanent duration the crystals were annealed. The fol- lowing results were obtained: Diamond: After annealing at 5000C for 725 h, the lattice spacing decreased from 3,592 kX to 3,574 kX. The intensity of the diffuse scattering maxima did not change noticeably. l'Ifter further annealing at 900 00 for 1 hour: 3,566 kX; the intensity of the maxima becomes noticeably lower. In the course of a further treatment at 12000C for 1 hour the-lat- tice s-oacing decreased still more.

However, it exhibits excess phases in its structurel the quantity of which varies in relation to the heat treatment given. The authors have investigated the nature of these phases 0 Specimens of steel were austenitized at 950 to 130; C, followed by water-quenching and subsequent soaking for loo, 400 and 1000 hours at temperatures of 500, 600 and 750*C.

After heat treatment, the specimens were dissolved electrolytically and the excess phases liberated; the latter were investigated by chemical and X-ray analysis (Ref 1). In Fig 3 and 4, from the results of chemical analyEis, the change of alloy element content in the electrolytic deposit and the total weight of the deposit in relation to the quenching and ageing temperatures is shown. By means of X-ray structural analysis it was found that the electrolytic deposit of the excess phases obtained from specimens quenched from 12000C and above, consists primarily of NbC (Fig 5a), having a lattice parameter of 4.42 kX. As the quenching temperature is lowered, the % carbide in the deposit decreases (Fig 3) and the q-antity of the intermetallic compound (MoNb)Fe2 increases (Ref 2); Cavd 2/4 the latter has a MgZn2 type of structure with lattice Ir 69694 S/126/60/009/03/017/033 E091/E435 On the Nature of Excess Phases in a Chromium-Nickel-Molybdenum- Niobium Stainless Steel parameters of a = 4.77 kX and c - 7.80 kX. An inflection in the "total weight" curves for the % element content in the electrolytic deposit can be observed at 1050 to 1150 aC. This is evidently associated with solution of the intermetallic compound at these temperatures. The transition of the alloying elements from the dispersed phases to the solid solution in this temperature interval is accompanied by some decrease in hardness and increase in specific electrical conductivity and specific impact resistance of the metal. The electrolytic precipitate of specimens, quenched from 1150*C and subsequently annealed for 100, 500 and 1000 hours at 750*C and for 1000 hours at 6000C, consists primarily of an intermetallic compound of the same structural type but the lattice parameters decrease to a = 4.755 kX and c = 7.738 kX; in the X-ray photographs of such specimens, lines corresponding to large reflection angles are widened considerably due to Card 3/4 changes in the unit cell dimensions (Fig 5b). The X-ray/ 69694 s/126/60/009/03/017/033 E091/E435 On the Nature of Excess Phases in a Chromium-Nickel-Molybdenum- Niobium Stainless Steel photographs were taken in K-Cr rays. Lengthy annealing at 5000C does not lead to separation of excess phases; at 6oo0C the process proceeds much more slowly than at 7500C. The chemical analysis shows a sharp decrease in Nb and an increase in Mo, Cr and Fe in the precipitate. These results enable one to assume that the intermetallic compound must correspond to the composition Mo(Fe,Cr)2. The molybdenides thus separating cause some change in hardness, UTS, % elongation and impact resistance of the steel (see Fig 2). There are 5 figures, I table and 2 Soviet references.

In the present work, molybdenum lamellar single crystals 0.03 mm thick and polycrystalline wires, 0.2 mm in diameter, were irradiated in a type RFT reactor. Irradiation was effected at up to 0 20 2 100 C with 1.23 x 10 neutrons/cm , of which 350% were fast. A great increase in diffuse scattering of X-rays was produced by irradiation (Fig. 16 compared with la). Laue patterns were obtained with a molybdenum anode. The lattice spacing increased from 3.1404 to 3.1414 +.0.0003 kX during irradiation. Specimens were subjected to stepwise annealing at 100, 2M 300, 350, 4oo, 450, 500, 6oo and 830 0C with holding times of 5-1 hours.

Measures were taken to ensure that the diffuse maxima and Laue spots were on the straight-line -part of the film-darkening curve. For photometry a type mF-A microphotometer was used. Fig. 2 gives photometric curves for spots from the (200) plane and the corresponding diffuse maxima for various anneal~ing temperatures, without annealing and without irradiation. Lattice disturbances were removed by annealing at 830 0C but not below. Fig. 3 shows oLaue patterns of an irradiated single crystal annealed at 830 Ctaken at room temperature and with cooling to liquid-nitrogen temperature. The author concludes from this work and from his previous work with Konobeyevski.y (Ref. 5) that the effects observed in the irradiated crystals are due to the same combination of defects that produce hardening and embrittlement.

A comparison of experimental data on the temperature dependence of diffuse scattering and chdnges! in mechanical properties and electrical resistance induced by neutroa bombardment I of molybdenum leads to the conclusion that all these phenomena are caused by I groups of defects which cause the formation of prismatic or annular dislocations that are stable up to temperatures close to the recrystallization point. An explanation of the abnormally high increase in the unit.cell of neutron-irradi--tted diamond is proposed: because of the rupture of the bonds in the lattice and a change from tetrahedral to trigonal coordination of the atGm* the cello of diamond are converted to graphitelike cells6 Orig, art, has: 5 figures and I table.

X-ray photographs showed structural variations in monocrystals with respect to deformation degree. Small defonutions caused extension of all the spots on the Laue diffraction patterns. Further stretching caused the disappear- ance of the Laue spots and the appearance of separate maxima of the characteristic radiation located Irregularly on the Debye rings. Still further deformation caused an orderly arrangement of the maxima. The maximum deformation (close to the rupture point) produced the appearance of an axial texture with L6017 axis.

The authors Investigated by an autoradi- !ography method the dependence of the rate of self-diffusion on the crystallographic direction in the two low-temperature phases of .'uranium. Earlier data on the self-diffusion in these phases are con- Itradictory. Apparatus was developed in which the self-diffusion icoefficient was calculated from the-rate of change of the a activity !on the surface of the sample during the course of annealing, as well C L 31s66,,66 ACCESSION Ma -"-AP5016929 !as by autoradiograpby of the surface of the sample. The investiga- :tions were made on singlecrystals, polycrystalline samples with large ~perfect grains and polycrystalline samples with imperfect grains. .The test procedure and the method of calculating the self-diffusion coefficients from the change of a activity and from the autoradiogram5' !are described. The results for a-uranium are listed in Table 1 of Ithe Enc-losure. The results~for-P-uranium are similar to those for :a-uranium, but the experimental conditions did not make it possible to lestablish the directions with the maximum and minimum self diffusion :coefficients.
