Title: Target plate for rifle and pistol reactive targets
Inventor: VERTANNESS JOHN ALAN
IPC: F41J1/01
Filed: 1987-11-26
Abstract: A target plate 1, for use with reactive target mechanisms, is made of rubber, rubber compounds or other elastic material. When a bullet or other projectile hits the target plate 1 the vibrations are detected by a sensor 4 which then activates the target mechanism 3 to move the plate 1 by means of an operating arm 2. The mechanism 3 will continue to operate even after a large number of bullets have hit the target; the number of hits being greater than a plywood target plate can accommodate. The target plate 1 will allow bullets to pass safely through it without ricochet, and can be hit by a large number of bullets without splintering, shattering or breaking. <IMAGE>

Patent GB-2225732-A (GB)
Title: Heating device with a catalytic burner
Inventor: BOTAZZI PHILIPPE
IPC: A45D1/02
Filed: 1989-11-17
Abstract: A heating device incorporating an induced-air catalytic burner (8), includes means (22) for confining a flame, for initiating the catalytic combustion, in the downstream zone (10a) of a heating element (10), but at a distance from the outlet face (8b) of the catalytic structure (8). After ignition, heat spreads from means 22 - preferably a screen or disc - by conduction and convection to the burner 8. This, when it reaches a particular temperature, catalyses the combustion of the fuel; the initiating flame downstream of means 22 thus goes out. Means 23 upstream of the catalytic burner 8, becomes hot and so preheats the fuel. Tube 9, at its downstream end, forms an air-tight seal with means 23 and, upstream, accepts a mixture of ambient air and fuel from an injector. The device may be used in a hair-curler. <IMAGE>

Title: Improving the selectivity of Fischer-Tropsch catalyst
Inventor: BELL WELDON KAY
IPC: C10G2/00
Filed: 1990-08-24
Abstract: A Fischer-Tropsch iron catalyst has improved selectivity for liquid hydrocarbons (reduced selectivity for methane) provided. The catalyst is prepared by treatment of the usual inactive catalyst precursor with water vapor at elevated temperature either after conventional activation by syngas or concurrently therewith. This treatment with water vapor does not affect catalytic activity. The resulting catalyst may be used to advantage either to increase temperature and throughput, or to increase liquid hydrocarbon selectivity, compared with conventional catalyst that has not been "selectivated". The exemplified catalyst is promoted with potassium and contains copper.

Title: Simulated leaded glass using heat-softenable plastic strip
Inventor: LARSSON KURT
IPC: B44F1/06
Filed: 1991-11-13
Abstract: Simulated leaded glass is produced by heating a strip of pvc or similar heat-softenable plastics with low memory characteristics. The strip has an adhesive backing by which the strip can be secured to a sheet of glass or other transparent material. At room temperature the strip is relatively stiff and hard wearing like traditional lead and, when heated, the strip can also be formed into curved shapes in the manner of traditional lead. The strip is also not susceptible to creep, which might result in lifting at overlaps and curves. <IMAGE>
Patent GB-913906-A (GB)
IPC: D03D51/00
Abstract: 913,906. Loom stopping and reversing mechanisms. COMPTON & KNOWLES CORPORATION. Oct. 5, 1959 [Oct. 17, 1958], No. 33642/59. Class 142 (2). Upon weft failure the loom is automatically stopped and the lay is reversed to its back position The lay 3 is reciprocated by a crank-shaft 4 having a gear 6 in mesh with a gear 30 fixed to a shaft 25 which may be rotated in either direction by a continuously rotating loose pulley 23. The pulley 23 has fixed to it a primary magnetic clutch 41, which normally drives the shaft 25 through a friction disc 39, and a secondary magnetic clutch 46 which is normally free. The secondary clutch co-operates with a disc 51 attached to a gear 50 loose on the shaft 25 and drives a second gear 62 loose on the crank-shaft 4 which transmits its motion back to the shaft 25 via a belt 64 and a pulley 53 fixed to the shaft 25, thus rotating the shaft 25 in the opposite direction to reverse the loom. The gear 30 has a disc 54 of a magnetic brake 56 attached to it. An electrical circuit is provided to control the clutches and brake. In operation, and upon weft failure, the primary clutch 41 is disengaged, the break 56 applied and, after a time lag, the secondary clutch 46 applied to reverse the loom to its back position where the clutch 46 is disengaged and the brake 56 reapplied. Upon correction of the weft defect and in the absence of a weft in the shed an electrical hold-off is maintained to enable the loom to restart without the weft failure mechanism unnecessarily restopping the loom.
