Title: Recording on thermoplastic photoconductor medium
IPC: G03G15/05
Filed: 1978-08-03
Abstract: A spot recording technique on a thermoplastic, photo conductor medium suitable for recording of high spatial frequency fringes is based on spoiling of the latent electrostatic fringes, formed on the photoconductor by uniformly charging and then exposing to a fringe pattern, by the spot exposure which partially or fully discharges the photo conductor. After heat development the recorded spots present themselves as partially deformed or nondeformed spots in the background of the fully developed relief grating. This technique allows the medium to be used in a wide variety of real-time applications including microfilm recording, optical data processing and bit-serial optical memories.

Title: Vehicle brake lock
IPC: B60R25/08
Filed: 1978-11-29
Abstract: 'The Vehicle Brake Lock' consists of the introduction into any part of the hydraulic brake line or cylinders of a non-return valve. This valve will allow the brakes to be applied but not released and so therefore rendering the vehicle immobile. The invention can be used as an anti-theft device or as an alternative to the hand brake. Any number of the vehicle wheels can be locked depending on where the valve is situated in the system. The valve would be released by use of an electrical solenoid but mechanical means of keeping the valve open can be used. <IMAGE>
Patent GB-784881-A (GB)
Abstract: 784,881. Engine turning-gear. BENDIX AVIATION CORPORATION. May 12, 1955 [May 13, 1954], No. 13752/55. Class 7(5) [Also in Group XXIV] A self-starter comprises a screw-threaded drive shaft 2 secured to the shaft 1 of a starter motor, a nut 8 mounted on the shaft 2 and a pinion 9 freely mounted on a smooth portion of the shaft 2 for movement into mesh with an engine gear 11, rotation of the pinion being effected through a friction coupling comprising discs 14 splined alternately on the nut and a barrel 13 'adapted to drive the pinion. As shown, the drive is effected through an overrunning clutch comprising a disc 23 which is keyed to the barrel and has teeth 24 engaging teeth on a flange 25 of the pinion 9. Longitudinal movement of the nut 8 consequent on rotation of the shaft 2 is transmitted to the barrel through springs 15 and a thrust disc 18 and to the disc 23 through springs 33, to mesh the pinion 9 with the gear 11, and further movement of the nut increases the pressure of the springs 15 on the clutch discs so that drive between the nut and the pinion 9 is established. In the idle position spring-pressed pins 29 press the overrunning clutch parts into engagement, and a radial spring-pressed latch engages a recess 38 in the shaft 2 to prevent drifting of the pinion 9, the recess having an inclined shoulder 39. If the pinion 9 fails to mesh when moved up to the gear 11, the springs 33 permit the barrel and nut to move forward while building up sufficient torque to bring the pinion into register whereupon the springs snap the pinion into initial mesh. The latch 34 then engages a recess 37 in the shaft 2. When the engine starts, the nut 8 moves back, the clutch teeth disengage, the latch is released by centrifugal force and the parts return to idle position.

Patent GB-2035760-A (GB)
Title: Playback apparatus with non- linear correction
IPC: G11B9/06
Filed: 1979-10-10
Abstract: In an information recovery e.g. a video disc playback apparatus, a playback cartridge 88 is utilized for the recovery of information from pre- recorded disc records 84. In one system, geometric variations are recorded on the surface of the record and are representative of recorded picture and sound information. As these geometric variations pass beneath the stylus, the capacitance between the stylus electrode and the surface of the disc varies in accordance with the recorded representations. The capacitive variations are converted to electrical signal variations in the playback apparatus. In such a video disc playback apparatus, sound interference in the video and video interference in the sound can be produced by the non-linearity of the aforementioned pickup stylus. Use of a non-linear aperture corrector 93 between the pickup circuitry 90 and the demodulator circuitry 96, 98 of the playback apparatus reduces these cross talks. Phase-shifting of the video and/or sound overcomes the interference and the degree of phase-shift may be fixed or varied according to signal level by a variably-biased diode in parallel with a capacitor. <IMAGE>
