Title: A process for the production of cinematographic films
IPC: G03B15/08
Filed: 1930-01-22
Abstract: 347,625. Kinematograph composite pictures. JELINEK, S., 32, Alserstrasse, Vienna. Jan. 22, 1930, No. 2230. [Class 98 (ii).] When producing kinematograph pictures by photographing a foreground scene on a stage in front of a screen on which a background scene is projected, the light used in projection is rich in ultra-violet rays and passes to the screen only through materials which are pervious to the ultraviolet range produced by the projecting lamp. In one form the optical elements of the projecting lantern and if desired of the taking camera are made of material, which is pervious to ultra-violet rays, such as quartz, fluor spar, or artificial resin. Objectives compounded of several lenses of different refractive indices may be used. The projection film made of hardened gelatine or celluloid may also be pervious to ultra-violet light. Alternatively the background scene is projected by a source emitting ultra-violet light within the range 400- 360 ÁÁ, to which range the usual photographic objectives are pervious. For this purpose an arc lamp having electrodes consisting of or containing calcium, aluminium, barium, strontium, potassium, magnesium, gallium or zinc may be used. The foreground is illuminated by light of less actinic quality than the projection light or by light of the same actinic quality but of comparatively low power. The method may be applied to the production of composite sound and picture films. The sound track on the background picture film may be either (1) made directly audible by a loudspeaker and recorded simultaneously with the projected background and foreground scene and sound; or (2) projected on the screen together with the background picture and photographed on the sensitive film the latter then consisting of one picture strip and two sound strips i.e., the photographed background sound strip and the foreground sound strip ; or (3) brought to the stage of modulated alternating current and the foreground sound superposed thereon by induction. In the latter alternative, two induction coils provided respectively for the background and foreground sound currents may together influence a third coil actuating a recording device, so that the relative intensities of the sounds may be controlled by varying the disposition of the coils.

Title: Improvements in and relating to telegraph relays
IPC: H01H50/54
Filed: 1947-01-24
Abstract: 620,633. Electromagnetic relays. STANDARD TELEPHONES & CABLES, Ltd., and TERRY, V. J. Jan. 24, 1947, No. 2282. [Class 38(v)] In a telegraphic relay in which two contacts carried by the armature are respectively brought into engagement with two fixed contacts according to the direction of movement of the armature, the two moving contacts and/or the two fixed contacts are mounted on a res'ilientlysupported rigid member so that one pair of contacts engages, the " give " of the resilient support causes a more rapid separation of the other pair. In the form shown in Fig 1, an extension 5 of the armature, which moves in the diredtion of the arrows 6, carries, by means of a rubber bush 8, a rigid member 1 bearing the movable contacts 2, 3 co-operating respectively with fixed contacts 9, 10. The arrangement may be modified so that the plane containing the contact faces 2, 3 and the axis 4 is not perpendicular to the direction of movement of the armature, thereby causing sliding of the contacts over each other, which further tends to diminish " chattering." In a further modification, Fig. 2, (not shown), the moving contacts are mounted on a spring blade which twists when the contacts engage and spring tongues engaging the moving parts provide friction to stop " chattering." In Fig. 3 it is the fixed contacts 23, 24 that are mounted on a rigid rod 26 which can rotate about its axis against bearing springs 28 and the armature causes an arm 20 carrying the moving contacts 21, 22 to rotate one way or the other about the spindle 29.

Abstract: 1457035 Monitoring position of sensing heads DSO "IZOT" 17 Jan 1974 [17 Jan 1973] 02287/74 Heading G1N [Also in Division G5] To check the radial position of a magnetic head 2, Fig. 1 from a central axis O, a disc 1 is located under the head for rotation about O, the disc carrying two circular tracks 4, 5, each comprising a series of magnetic marks and spaces, with the marks of one track coinciding radially with the spaces of the other track. The tracks are located at such radial distances that when the head 2 is correctly positioned it overlaps both tracks equally. Thus, when the disc is rotated, the output signal from the head is as shown in Fig. 2 if it covers one track more than the other, and is as shown in Fig. 3 when correctly positioned. The curves of Figs. 2 and 3 are obtained on an oscilloscope, and can also be used to indicate the magnitude and phase position of eccentricity of the spindle on the axis O with respect to a zero position defined by a notch 31.
