Patent GB-2119083-A (GB)
Title: Optical fibre gyroscope
Inventor: CULSHAW BRIAN
IPC: G01C19/72
Filed: 1982-03-08
Abstract: Light from laser (3) introduced into a first end (A) of an optical fibre loop (1) travels to end (B) and after interference with a beam from the same laser (3), but frequency shifted by a Bragg cell (10) or the like, is detected at 11. A detector (13) functions similarly for a counter-rotating beam passing from end (B) to end (A). A signal processing device (16) generates from the outputs of the detectors (11,13) a signal representing any rotation of the fibre. It is said that various types of noise are eliminated or reduced in this system. Noise reduction is also provided by frequency modulating the laser light on a sawtooth pattern (via Bragg cell 17 or modulating the loser itself). In a second embodiment, Bragg cell 10 is omitted and such modulation of the laser frequency combined with the optical transit time in loop 1 provides the frequency difference between the interfering light beams. <IMAGE>

Title: Pulse power supplies
IPC: H01S3/097
Filed: 1982-04-13
Abstract: A pulse generator comprises a wound, air-gapped core 1, a switch 10 for setting up an initial current flow in the winding 4 and hence a flux in the core 1, and a motor driven inertial-mass system (12 - 15) including a series of air-gap filling members 13 which move in and out of the core air-gap in succession. The switch 10 sets up the initial flux while one of the members 13 is in the air-gap 2 whereupon the work done in moving the member out of the gap augments the flux energy. Before or after such augmentation, the output conductors of the generator are brought into the circuit to receive the augmented energy as an electrical pulse. The generator may stand alone or be combined with a further energy storage stage including a capacitor and a switch for discharging the capacitor to a load, for example, a gas-discharge laser. <IMAGE>
