Title: Cancelling the remanent deflection in a piezoceramic head- support means of a video recorder
IPC: G11B5/588
Filed: 1979-04-30
Abstract: When a helical scan video- recorder is switched between operating modes, eg. play back to record; an oscillating signal of limited duration and decreasing magnitude is supplied to the piezoceramic means supporting the transducing head, to cancel remanent deflection in the support. The maximum magnitude of the oscillating signal is less than Ec, wherein Ec is the largest magnitude of signal to which the piezoceramic means responds, but larger than the normal tracking control signal supplied to the support. The tracking control signal may comprise an oscillating "dither" signal and, if the recorder is being operated at a tape speed other than the normal playback speed, a sawtooth signal to cause the support to bend to follow the oblique tracks. <IMAGE>

Title: Improvements in optical cables
IPC: G02B6/44
Filed: 1979-06-05
Abstract: An optical cable has dielectric optical waveguides contained in helical grooves 3 of a central filament 2, which has been formed by extruding plastics over a central stranded wire member 1, the grooves 3 following helical paths which may be of alternately opposite lay direction along the filament. The plastics of the filament 2 is extruded from a stationary die 9 through which the wire member 1 is drawn, the filament being engaged downstream of the die 9 and twisted in alternately opposite directions so that the grooves 3 formed by the die 9 are caused to follow helical paths where the plastics exits from the die 9. The extruded filament 2 may be twisted by blades 18 (or wheels) of a rotated sleeve 16, which engage in the grooves 3, or alternatively by means of wheels of resilient material which engage the surface of the filament 2. Dielectric optical waveguides are disposed in the grooves 3 and the whole is surrounded by an extruded plastics sheath to produce the optical cable. <IMAGE>

Title: Photographic camera with electric flash
IPC: G03B15/05
Filed: 1979-06-22
Abstract: A photographic camera with a flash provision makes use of an electromechanical mechanism of which one part (27) has two possible operating positions, specifically against and away from solenoid M1.

Title: Digital waveform generator
IPC: H04Q1/457
Filed: 1979-09-24
Abstract: A digital waveform generator comprising means (e.g. clock generator 1, programmable dividers 2,3 and bistables 4,5) for generating two pulse trains of different frequencies and means (e.g. EXCL-OR 7) for combining them to form a pulse width modulated pulse train (C, C') which has a "low frequency component" (D, D', D'') the frequency of which is equal to the difference between the frequencies of said two pulse trains and the form of which is determined by the said pulse width modulation itself dependant upon the duty cycles of the two pulse trains. For generating sine waves the low frequency component is of substantially trapezium waveform (D) with horizontal portions, interconnected by ramp portions, forming one-sixth of the wavelength of the trapezium waveform. Such a trapezium waveform approximates to a sine wave with less than 5% distortion. This sine wave is generated by combining two different frequency pulse trains (A and 13), one with a one-half duty cycle, one with a one-third or two-thirds duty cycle, in an Exclusive OR gate (7) and passing the result through a low-pass filter (8). The generator is easily realized in integrated circuit form and is suitable for use in Multi-frequency touch-tone dialling equipment. <IMAGE>
