Title: Process for the production of cooling or cooled elements which are subjected to high thermal loading
Inventor: HEYBUTZKI HELMUT
IPC: C25D7/04
Filed: 1987-09-01
Abstract: A cooling or cooled element designed to take high thermal loads is produced using a support 1. Cooling tubes are inserted into grooves 2, 3, 4, 5; their ends are sealed into grooves or bores in side parts which fit in recessed regions 6, 7. Copper is electrodeposited over the surface of the support and cooling tubes. It is then machined to a flat surface. Bores 8, 9 contain bolts (19, 20; Figs. 4-6) which become attached to the copper plate (25) formed. These bolts (19, 20) can be pushed upwards to remove the copper plate (25) from the support. The plate may then be turned over and a further layer (28) deposited on the other side. The element is finished off by connecting the cooling tubes to collecting ducts and machining through- passages into the plate. The procedure may be used to make accelerating grids for neutral particle injection in fusion reactors. <IMAGE>

Title: Disc brakes
Inventor: HEINLEIN CARL EDWARD
IPC: F16D55/226
Filed: 1987-09-02
Abstract: A motor cycle disc brake arrangement which overcomes at least some of the problems associated with the prior art comprises a disc brake (1) and a fork leg (5) of a motor cycle, which fork leg (5) rotatably carries a wheel, the disc brake (1) being located between the fork leg (5) and wheel so as to co-operate with a braking disc (9) mounted on the wheel. The brake (1) is preferably located symmetrically on the fork (5), thus reducing the moments of force resulting from brake application and keeping the brake (1) out of sight and away from the weather. The brake may be of the single piston, sliding caliper type, or of the opposed pistons, fixed caliper type. <IMAGE>

Patent GB-2234619-A (GB)
Title: Determining thickness of coins
Inventor: ALLAN RICHARD DOUGLAS
IPC: G07D5/02
Filed: 1989-07-28
Abstract: A coin validator (2) has a thickness sensor formed by two coils (10, 12) positioned one on each side of the coin path. The coil outputs are processed separately using a look-up table (20) to derive values which are linearly related to coin position across the width of the passage, using the same constant of proportionality for both sensors. Accordingly, by combining the processed outputs there is derived a value which is independent of coin position and which can be peak-detected to indicate thickness.
