Title: Semiconductor body and light emitting or other device thereon
Inventor: ETTENBERG MICHAEL
IPC: H01S5/042

Title: Variable magnification photocopier
Inventor: LANE JOHN NORMAN
IPC: G03G15/041
Filed: 1983-09-21
Abstract: A variable magnification line by line photocopier employing full and 1 DIVIDED 2 rate scanning mirrors has the position of the lens (18) and relative position of minor carriages controlled by a single motor (54) and single detent (95,87) moving means (56). To change magnification, solenoid (85) is energised to release pins (87) and (97) from their respective notches (89, 96), thereby releasing 1 DIVIDED 2 rate carriage (41) and lens carriage 82. Reduction motor (54) is switched on and starts driving shaft (91) (and thereby 1 DIVIDED 2 rate carriage 41) and lens carriage (82). Solenoid (85) is then de-energised and notched locating disc (90) is latched at correct position, preventing further rotation of shaft (91) and arresting motion of 1 DIVIDED 2 rate carriage, and clutch (84) slips allowing continued movement of lens carriage (82) until this also latches in correct position in plate (82) causing motor 54 to be switched off as pin 95 locates. <IMAGE>
Patent GB-2150502-A (GB)
Title: Self-braking ribbon transport apparatus
Inventor: GRAHAM JOHN FLETCHER
IPC: B41J35/36
Filed: 1983-12-01
Abstract: In a tape transport mechanism, a payout reel (10) is supported on a shaft (22) whereabout is wound a helical spring inertia brake (90) fixed at a first end (92) and free at a second end (96), wound such that rotation of the payout reel (10) in response the drawing therefrom of ribbon (12) tends to cause the helical spring inertia brake (90) to be wound more tightly onto the shaft (22). A portion of the ribbon (12) passes onto a projection (98) on a tension arm (86) which engages the second free end (96) and unwinds the helical spring inertia brake (90) to allow rotation of the shaft (22) opposed by a predetermined amount of torque to maintain tension in the moving ribbon (12). When the moving ribbon (12) ceases to be drawn from the payout reel (10), the tension arm (86) moves back for the projection (98) to allow the helical spring intertia brake (90) once more to grip the shaft (22) and bring the payout reel (10) rapidly to a halt.   <IMAGE>

Title: Silicon transducer
Inventor: HODGES ROBERT JAMES
IPC: G01P15/08
Filed: 1984-12-13
Abstract: A transducer which uses a thin silicon strip 1 as its responsive element has a piezo-resistor strain gauge 2 embedded in the silicon near its mounted end. To adjust the resonance characteristics in a desired manner the free end of the silicon element has a small magnet 3, with another magnet 4 in repelling relation therewith. It is also possible to have two magnets, one on each side of the element's free end (Fig. 3, not shown). In a disc-like transducer (Figs. 5 to 7, not shown), a set of piezo-resistors are located around the disc, with a small magnet at its centre, with one or two magnets adjacent thereto, in the same way as for the strip-like element. In all cases the magnets near to the silicon can be replaced by electromagnets (Figs. 8, 9, not shown). The transducer may function as an accelerometer to detect lack of lubrication in bearings, and a scanning accelerometer may be provided by supplying the electromagnets with scanning currents. In its disc-like form the transducer may function as a microphone or a scanning microphone for use in determining engine characteristics and/or faults. <IMAGE>

Patent GB-2189806-A (GB)
Title: Briquette hardening
Inventor: MITCHELL WILLIAM
IPC: C10L5/28
Filed: 1985-10-26
Abstract: Shaped briquettes for use as a smokeless or smokey combustible solid fuel are manufactured by firstly compressing a mix of agglomerated solid fuel particles and a binding agent such as resin and starch or a lignosulphonate to produce "green" briquettes of low compression strength. The green briquettes are then treated in a fluidised bed dryer, (such as in a horizontal vibrating fluidised bed dryer, with air at elevated temperature - e.g. 120 DEG -220 DEG C) for a period of time sufficient to bring about partial or complete hardening and curing of the green briquettes. If further hardening and curing treatment is required to increase the compression strength of the final product to an acceptable level, a retort oven or another fluidised bed dryer may be used. A process is also disclosed using a static fluidised bed dryer with sand as a heat transfer agent instead of a horizontal vibrating fluidised bed dryer.
