A portable sound and motion picture of the type hand held for operation utilizes a film having a magnetic sound track thereon and includes within the casing a magnetic transducer, tape driving means, an amplifier with external gain adjustment, terminals for connecting a power source and applying an intelligence signal, and an external switch for controlling the driving motor. Electric motor 68, Fig. 7, which is speed controlled by a governor 73 and arranged to drive through a slipping clutch 58, drives a film-strip claw feeding arrangement 56, Fig. 17, through a shaft 54, rotates a shutter disc 60, Fig. 18, across a camera aperture 64 and projection aperture 63, and rotates a ballbearing mounted, silicon oil damped toothed capstan 89, Fig. 19, to feed the tape from a supply spool to a loop forming cavity 36, Fig. 5, in which the claw 56 and a retractable pressure shoe 42 driven also by the motor feeds the film over a straight wall portion in registry with the lens system carried by turret 26. A shockabsorber 86 is provided in shaft 69 to damp claw impulses and a coupling 83 is provided whereby the shaft may be driven from an external source of power. The film sound track is passed through an air gap 127 adjacent a magnetic transducer 126 against which it is pressed by a shoe 127a, and an intelligence signal, which may be from a microphone in a jack 132 after amplification in valves mounted within the capstan assembly 87, is recorded. A point source exciter lamp 134, Fig. 14, the illumination of which is responsive to the recording amplitude being provided to superimpose on the image in view-finder 29 by means of mirrors 138, 140, a visible signal indicative of the recording level so that amplifier gain adjustment may be effected during photographing. The film magazine is detachable from the main camera body and includes a lever arm to indicate the amount of film on the supply spool. The camera casing may include a light 141 to permit optical sound recording on a second track on the margin of the film. A projector casing, Figs. 15, 16 (not shown), incorporating a loudspeaker, a driving motor and the necessary circuits includes a recess in which the camera can be seated to utilize a projection lens 27 its optical system for projection purposes. External spool arms are seated in a pocket in the casing and locked thereto and the positions of the take-up and supply spools are made adjustable. The camera cover which is detached during projection is arranged to be irreplaceable whilst a light reflecting mirror is turned to send light to the lens 27.

Title: Improvements in or relating to coding apparatus
IPC: H01J31/04
Filed: 1960-09-21
Abstract: 897,469. Cathode-ray tubes. SIEMENS & HALSKE A.G. Sept. 21, 1960 [Sept. 25, 1959], No. 32417/60. Class 39(1). In a tube for converting electrical signal information into coded pulses, the coding mask 7 is a thin-walled body having an external surface which is a surface of revolution; is provided with apertures in accordance with the code to be used; and surrounds at least a part of the collecting electrode 9. As shown an electron beam is rotated about the axis of the tube by electrostatic or magnet means 2 and is focused and deflected towards the coding mask by cylindrical electrode 4. The input signal information is applied across a pair of deflection electrodes 5, 6, the field between them causing the beam to be deflected to a corresponding row of apertures in mask 7, means being provided to maintain the input voltage constant for one revolution of the electron beam. For a binary code each row of apertures in mask 7 corresponds to a particular power of two in the binary scale. Preferably, the difference between the number of apertures in two adjacent rows of mask 7 is unity. In an alternative arrangement, the electrode 5 may be replaced by a delay line, e.g. a helix of toroidal form, the velocity of an electromagnetic wave along the delay line being equal to the velocity of rotation of the electron beam. The output end of the delay line is closed by a load resistor, the signal information being applied to the input end. The small space between the ends of the delay line may be used for the generation of time markers. In this arrangement the counter electrode 6 may be omitted. Instead of being cylindrical the surface of mask 7 may be spherical, conical or paraboloidal. Wire collector electrode 9 is supported centrally by the tube envelope, and mask 7 is supported on wire 9 by ceramic insulators.
