Abstract: 1424770 Mounting disc brake pads; noise preventing; wear detecting SUMITOMO ELECTRIC INDUSTRIES Ltd and TOYOTA JIDOSHA KOGYO KK 19 Oct 1973 [21 Oct 1972] 48872/73 Heading F2E A resilient member for attachment to a backplate of a movable friction pad of a disc brake comprises a resilient arm for engaging with and tensioning an electric wire of a wear-sensing means of the friction pad, and a guide portion arranged for resilient engagement with a guide housing of the friction pad. As shown, one end of a resilient member 15 in the form of a two-armed wire torsion spring is formed as a loop 16 for retaining and exerting a tension on at least one portion 11, extending between a hole in groove 12 and a sleeve 14, of an insulated electric wire 7 forming part of a warning circuit for indicating when the limiting thickness 10 of a brake lining 9 has been reached. The middle portion of spring 15 is looped at 6 around the periphery of a pin 17 supporting friction pad 3, and straddles the upper edge of the backplate 4. The other end extends along the plain side of backplate 4, and through a hole 19 to the front at 20. Loop 6 around pin 17 extends circumferentially beyond the backplate periphery, contacting surface 21 of a guide member 2, whereby edge 5<SP>1</SP> of backplate 4 is urged into contact with surface 21<SP>1</SP>. All noises such as squeal are thereby eliminated. The part of electric wire 7 extending backwards through the hole in groove 12 (of pad 9) and backplate 4 is returned upwards and forwards through hole 19 to form portion 13 (see Figs. 1 and 2) also passing through sleeve 14. In operation, when that part of portion 11 lying at the end of groove 12 is worn away by contact with the moving disc 1, the remainder is separated by the flexure of arm 8 of spring 15 to break the circuit and thereby produce a warning signal.

Abstract: 1437933 Projectile fuzes SARMAC SA 21 Nov 1974 [26 April 1974] 50495/74 Heading F3A A projectile comprises an explosive relay 3, Fig. 1, which is displaced from within a recess in an explosive charge 2 of the same explosive material into the proximity of, or into contact with a detonator 7 to arm the projectile. A spring 30 displaces the relay after the projectile has been launched and when an occlusion 13 has moved aside owing to centrigual force following the release of locking balls 14 by an inertia sleeve 17. The relay is alternatively released by the controlled rotation of a cylinder 52, Fig. 4, when a bore 53 in the cylinder is aligned with the relay, and through which it can pass. An inertia sleeve 54 retains locking balls 63 for the cylinder. In an embodiment of a hand grenade, Figs. 11 and 12 (not shown), the rotatable cylinder is rotated by a sprung lever when the grenade is released. In other embodiments the relay is locked by sprung dogs or an elastic ring. The detonator is fired on impact by a striker 10, Fig. 1, which at launch is moved adjacent the detonator by the limited set back of a carrier 21 following the shearing of a mat 23 or the expansion of an elastic ring (not shown). The striker and a primer for the detonator, in a further embodiment, are coupled together and are displaced rearward at launch. In another embodiment the striker has an elastomeric tip which is brought to bear against the detonator at launch. In yet another embodiment "all-ways" actuation is ensured by a ball above the striker. The detonator may also be fired by piezo-electric means.

Under the control of the bars 6, a group of four articles 1 is moved up guide surfaces aligned with rail sections 77a so that each article is tilted outwards by a guide rail 89 continuing from one of the guide surfaces. The forward edge of the first pair of articles engages the front wall of a tray held on the conveyer 4 by spring-loaded stops 69. As they pass off the ends of the rails 89 the tilted articles fall by gravity into the tray, the tilting having ensured that they are seated within the tray side walls. The pressure exerted by the articles on the front wall of the tray tilts the rear of the tray upwards, Fig. 4 (not shown), before the loaded tray is discharged by gravity on a roller conveyer 9. The trays may be manually delivered to the loading position. The machine may be used to load containers with hinged cover flaps which are held outwards during the loading operation.
