Abstract: 252,419. Viewers, Ltd., and Johnson, F. G. L. Jan. 22, 1925. Projectile fuzes. - Relates to safety devices of the kind comprising rearwardly extending weighted arms which move out by centrifugal force during the rotation of the projectile. According to the invention, a spindle D is arranged at right angles to the axis of the fuze, and is provided at each end with rearwardly extending weighted arms D<2> so arranged in relation to the axis of the fuze that centrifugal force can swing them out onlv when forward acceleration is over. This device may move (1) a flash obturator, or (2) a shutter between the firing pin and the detonator, or (3) the detonator into line with the firing pin, or any combination of these safety arrangements. As shown, the spindle D contains the detonator D<1>, which, in the safe position, is out of line with and screened off from the firing pin C and also cut off from the flash passage below it (not shown); moreover, the firing pin is held off by arms D<x> on the spindle D. The spindle D is itself locked in the safe position against a stop a<2> by spring-controlled centrifugal hooks. These hooks move out and release the spindle when centrifugal force begins, but the weighted arms D<2> do not swing out until acceleration is over. When the outward swing of the arms D<2> occurs, the arms D<x> release the striker C, and the rotation of the spindle D brings the detonator D' in line with and exposed to the firing pin C on one side and the flash passage on the other side. The firing pin is situated a short distance behind the direct-impact striker B, and a hollow collapsable washer B<1> is provided behind the head b of this striker as described in Specification 258,467.

Abstract: 1414691 Capacitive switches WESTERN ELECTRIC CO Inc 16 Jan 1973 [18 Jan 1972] 2181/73 Heading H1M A capacitive signalling device comprises a film electret 11 with a metallized coating 12 on one surface the other surface being spaced from a back plate comprising single electrode 14 (Fig. 1) or a plurality of electrically interconnected electrodes 25, 26, 27 (Fig. 2), a different electrostatic condition existing between the metallized electret film and the electrode(s) at each of a plurality of locations, a utilizable signal unique for a particular location being obtained when the film is displaced, as by actuating a push-button 15, towards the electrode. The different electrostatic conditions may be achieved by charging the film 11 to different extents # 1  to # 4  (Fig. 1) at the various locations, e.g. by forming the film using electron beam scanning (Fig. 4, not shown) with suitable shielding. The charged distribution may be in parallel rows, or a chequered pattern. Alternatively the electret film may be uniformly charged and the distance between it and the electrode may vary, e.g. by varying the thickness of the individual electrodes, (Fig. 3, not shown), or film at the various locations, or by varying the area of the electrodes (Fig. 2). Two or more of these different methods may be embodied in a single device to increase the number of touch locations, and regions of opposite electret polarity may further be employed. Push-buttons 15 may be restored to their rest positions by the resilience of film 11, which may be of fluorinated ethylene propylene copolymer, or by supplementary means. Alternatively the film may be displaced by a finger through an apertured cover-plate.
