A method of moulding sheet material, e.g. asbestos fibre sheet impregnated with a thermosetting resin, e.g. a phenolic resin, comprises lining a mould 1 with the impregnated sheet material 2, placing over the lining a flexible sheet 6 of silicone rubber, and curing the resin at an elevated temperature while urging the silicone rubber sheet into contact with the lining to exert pressure thereon. Preferably the pressure is exerted by evacuating the space between the sheet 6 and the mould 1, and the sheet 6 may be provided with a network of channels 7 which communicate with evacuation nozzles 8. The sheet may be provided around its periphery with an upstanding ridge 9 which engages a corresponding groove around the periphery of the mould to form an airtight seal. The assembled mould may be placed in an oven, or the mould itself may be provided with an electric heating element. The process may be applied to the moulding of a chair or settee frame, in which case a metal strip may be embedded in the periphery of the impregnated sheet to provide means for securing upholstery covers to the frame. The silicone rubber sheet may be formed by lining the mould shell 10 with a suitable material, forming on the lining a number of intersecting ridges arranged in the pattern desired for the evacuation channels 7, applying a cold cure accelerated silicone rubber latex preferably by spraying, and allowing it to set. A reinforcing layer of hessian may be embedded in the silicone layer.

Title: Multi-exposure device for photographic cameras
IPC: G03B17/30
Filed: 1970-10-09
Abstract: 1329563 Winding and tensioning mechanism NIPPON KOGAKU KK 9 Oct 1970 [9 Oct 1969] 48155/70 Heading G2A In a camera in which the rotation of a shaft winds on the film and at the same time tensions the shutter, the shaft can be uncoupled from the film winding mechanism, so that rotation of the shaft can re-tension the shutter without advancing the film. Thus multiple exposures may be made on the same picture area. As shown, a film winding lever 1, to which is secured a cylindrical part 3, rotates a winding shaft 6 which is fitted into a hole in a plate 5. The plate carries a pin 4, and a pawl 8 on a pawl shaft 7. Pawl 8 is spring biased so as to bear against a three-blade cam 10 which is secured by a pin 11 to a gear 12, the gear fitting rotatably over a film take-up bearing 13. Gear 12 meshes with idle gears 14, 15 and 20 to rotate a spool gear 21 and retainer 22, and hence the spool 23. Thus when winding lever 1 is rotated, the movement is transmitted to the plate 5 and hence the pawl 8. A downwardly extending lug 8a on pawl 8 engages against a stepped face 10a of the cam 10, thus rotating it and hence gear 12. As explained above, rotation of gear 12 causes the film to be wound on. Idle gear 15 also meshes with a sprocket gear 17 which rotates a shaft 19, thus rotating a film transport socket. The shutter release is actuated by means of a plunger 24, 25, 26. Round the release button 25 fits a rotatable setting ring 28 which carries an indicator pointer (28b), Fig. 2 (not shown). When this pointer is set against a fixed mark (2a) on the camera housing, the mechanism is set for normal operation as described above, i.e. rotation of the winding lever both tensions the shutter and winds on the film. When the ring 28 is rotated so that the pointer is set against a second fixed mark (2b), a profiled portion 28a of ring 28 engages a similarly profiled portion 30a of a cylinder 30 surrounding the plunger 26 and rotates it a corresponding amount. A gear portion 30b at the lower end of cylinder 30 transmits this rotation via an idle gear 33 to a gear 34 which has a bifurcated end 34a embracing a projection 35a of a member 35. This fits over the upper end of film take-up bearing 13. Thus the rotation of ring 28 is eventually transmitted to member 35, which pivots the pawl 8 outwards, so that it does not engage the cam 10 at all-when it is rotated by lever 1. Thus rotation of lever 1 does not now affect cam 10, and consequently no film transport takes place, although the shutter can still be tensioned.

A pipe coupling comprises a spigot 12 and a socket 13 carried by arms 29, 31, e.g. on a tractor, detent balls 19 in the socket engaging a groove 25 around the spigot and an axially slidable lock sleeve 22 surrounding the detent balls to hold them in locking position, pulling the spigot 12 rightwards sliding the socket 13 relative to the arm 29 and to the lock sleeve 22, held by the arm 31, compressing a spring 23 between the sleeve and socket until an enlarged portion 26 of the sleeve is aligned with the detent balls 19, Fig. 6 (not shown), which are then free to move radially outwards, releasing the spigot for withdrawal from the socket. To reconnect the coupling, the sleeve 22 is slidden leftwards manually, Fig. 8 (not shown), against the bias of its spring 23, the bracket 29 holding the socket 13 fast, until the enlarged sleeve portion 26 again is aligned with the detent balls 19, which are then free to move radially and allow reinsertion of the spigot 12.
