Title: Explosive charges
Inventor: TRINKS DR WALTER
IPC: F42B1/02
Filed: 1979-07-19
Abstract: An explosive charge for missiles for attacking armoured targets, comprises at least two plates 101, 111 clad on their rear sides each with a layer of explosive 12, 13 and adapted to be fixed in an operational attitude in which they are contiguous to each other and form an angle of less than 180 DEG , and an igniter adapted to ignite the layer of explosive of two plates simultaneously. The plates are preferably interconnected by a hinge device which enables the plates to be swung open into the operational attitude from an attitude in which they are disposed substantially parallel to each other, the hinge device being mounted on a propulsion-unit chamber which supports a device which causes the plates to swing open at a preset distance from the surface of the target. The plates may be curved substantially cylindrically and the thickness thereof preferably diminishes from the mutually- proximate edges in the outward direction. The layers of explosive preferably overlap the edges of the plates, each layer may contain explosive zones with different detonation velocities for directing the detonation waves. <IMAGE>

Title: Key switch
IPC: H01H13/02
Filed: 1980-07-22
Abstract: A key switch, for instance for data entry keyboards, has a housing (11-16) supporting a snap-action spring (32) with a movable contact portion (35) positioned adjacent a fixed contact (58) on the housing. An actuator leaf spring (48) is anchored at one end of the housing, and has a free end (50) which is movable to drive the snap-action spring (32) between first and second bi-stable positions to operate the switch.

Title: Lamp monitoring circuit
Inventor: EMBREY DEREK MORRIS
IPC: B60Q11/00
Filed: 1982-09-28
Abstract: In order to provide a circuit for monitoring the filament of a lamp L, both when the lamp is illuminated and when it is non-illuminated, a sensing resistance RS is connected in series with the lamp L. When lamp- energising switch S1 is closed this gives rise to a potential difference which can be sensed by an amplifier IC1. There are also provided additional resistances R1 and R2 so that when switch SW1 is open a reduced current flows through the lamp Land generates a potential difference across the augmented sensing resistance formed by resistances R2 and RS. This potential difference is similar to that developed across RS alone when SW1 is closed. <IMAGE>
