Title: Reactive ballistic protection device
Inventor: WEIHRAUCH GUNTER
IPC: F41H5/007
Filed: 1988-04-08
Abstract: A reactive ballistic protection device includes an electromagnetic launcher accelerating a missile towards an approaching projectile, the missile colliding with the projectile before it reaches the object to be protected. A stack of protective elements B may be housed within a recess in the outer wall A of an armoured vehicle, each comprising a primary coil D, a secondary coil E, and a missile C. The primary coil D may be a flat metal wire coil while the secondary coil E may be a circular plate, the two being potted with an evaporative compound, while the disc-shaped missile C which is attached to the coil E may be made of a hard ceramic material, or be designed as a high explosive charge (Fig. 2e). The projectile is identified by a co-ordinating system on the basis of data determined by twin sensors S and the primary coil D connected to a power supply, eg. a bank of capacitors, the resulting current surge disintegrating the coils and evaporating the potting compound. As a result, the missile C gains thrust from the secondary coil E and from a vapour cushion.

Title: Airline lubricators
Inventor: ROYAL JOHN DESMOND
IPC: F16N7/30
Filed: 1988-04-15
Abstract: An airline lubricator includes a housing (2) for connection to an airline, the housing (2) mounting a deformable cartridge actuatable by the air pressure within the housing to discharge lubricant into the airline 21 to lubricate equipment powered by the airline. The housing also includes an airflow passage (38) through which air flows to the equipment. The passage (38) is adjacent to the cartridge when mounted within the housing so that deformation of the cartridge under the air pressure in the housing on depletion of the lubricant at least partly blocks the air passage (38) to at least reduce the air supply to the equipment. This gives an indication to the operator that the lubricant cartridge is depleted. <IMAGE>
