Title: Digital timing edge generator for special effects
Inventor: POHL WINFRIED
IPC: G06T13/00
Filed: 1990-10-24
Abstract: The stepped form present when an oblique line is formed by a digitally produced keying signal, e.g. for trick or animated figures mixing or cross-fading, due to the position on the scan lines being determined by pulse edges from a clock 1 coupled to a line frequency signal, is reduced by selectively introducing delays into the clock pulses. Curve or ramp data related to the selected line is clocked from a PROM 5 and multiplied by a selected factor at 7 to provide most significant bits 9 and least significant bits 9'. The latter control a delay line 4 acting on the clock pulses before they reach a T input of a programmable ramp counter 3. After a signal having 12-bit resolution has been added to signal 9 for controlling positional change of the line, it is also fed to the counter 3, at a D input. The output of counter 3 is D/A converted and applied together with a reference voltage 16 from a fading lever to a comparator from which the final keying signal 17 is produced. <IMAGE>

Patent GB-2262254-A (GB)
Title: Fastener applicator
Inventor: BURLINGTON GEOFFREY MICHAEL
IPC: B25C1/06
Filed: 1992-12-10
Abstract: A fastener applicator, for example for cable clips, uses the kinetic energy of a flywheel (6) rotated by a prime mover (4), preferably a battery drive electric motor, to drive a striker (8) for firing a fastener into a support. An actuator (7) which strikes the striker (8) may be a fixed projection on the flywheel (6) or be an element on the flywheel movable relative to the flywheel by centrifugal force to project the actuator from an inoperative position to an operative position for striking the striker. The driven from the prime mover (4) to the flywheel (6) is through a clutch or releasable drive coupling (26) which temporarily disconnects the drive when the actuator strikes the strike so that the kinetic energy at the flywheel alone drives the striker and the prime mover is protected from the impact. In a modification a micro-processor measures the rotational speed of the flywheel and stops the prime mover when a pre-determined speed for the necessary kinetic energy is achieved. <IMAGE>

Filed: 1995-03-13
Abstract: A flaw is put in an optical fiber to be cleaved, and a predetermined stress and strain is applied to the optical fibre in the vicinity of the flaw to cause curved-angle cleaving of the optical fiber at the flaw. In one embodiment first and second portions of the optical fiber are fixed, e.g. by clamping, and a flaw is introduced into the optical fiber between the first and second portions. Then, a concentrated force is applied to the optical fiber between the flaw and the first portion of the optical fiber, on a side of the optical fiber opposite the flaw, in order to cause the optical fiber to cleave with a curved-angle cleave. Another embodiment applies a concentrated force to the fiber before introduction of the flaw. Apparatus includes first and second pairs of optical fiber clamps separated by first predetermined distance, a flaw-producing device that produces a flaw in a fiber clamped between the clamps, and a force-applying device that applies a concentrated force to the fiber at a second predetermined distance from the first pair of clamps, the flaw-producing device being located between the force-applying device and the second pair of optical fiber clamps at third predetermined distance from the force-applying device, the distances being selected to produce a curved-angle cleave. A conversion kit is useable to convert an existing square-angle optical fiber cleaver into a curved-angle optical fiber cleaver. <IMAGE>
