Convention date, Dec. 20, 1933. [Class 97 (i)] The margin of a detachable cover 25 constituting one side wall of a film magazine bears against the edge of a flange 11 on the fixed side wall 10 whilst the central part of the cover is secured to and flexed towards the film supports 16, 19, carried by the fixed side wall. The supports 16, 19 may be formed as spindles carrying supply and take-up cores 15, 18. The cover 25 is formed with a flange 26 and may have a shape which is outwardly convex so that when it is secured by bolts 27 which thread into holes 28 in the ends of the spindles 16, 19, it is flexed into a plane. Alternatively, the cover may normally be flat and be flexed inwardly from its plane into abutment with the spindles 16, 19. The film is fed in the, magazine in preformed loops, the film sprocket including a cap 31 and toothed disc 32, one end of the cap 31 having teeth 35 which gear with pinions 36, 37 to drive the take-up spool. Embossings 39 in the fixed side wall 10 prevent the edges of the film coming into contact with the gears 35, 36, 37. The film passes from the supply spool 15 beneath the sprocket 32 and in a loop to the exposure gate returning in a loop and a superposed layer on the sprocket 32, to the take-up spool 18. The pressure rollers 40 are grooved to avoid the teeth on the sprocket 32. A latch device 44 rides over the teeth of the pinion 37 and prevents reverse rotation. Aligned exposure apertures 45, 50 are formed centrally between the side walls in the flange 11 and in an auxiliary wall 46, and may be closed bv a flexible slide 47. The film is displaced laterally into a position opposite the apertures by bosses 53, and is held in the gate by a pressure member 55. Specification 449,120 is referred to.

Abstract: 1,077,355. Delivering sheets. GEVAERT PHOTO-PRODUCTEN N.V. Sept. 10, 1964 [April 22, 1964], No. 37126/64. Heading B6H. [Also in Division G2] After being processed and pressed together to effect an image transfer, the image-receiving sheet 19 and light-sensitive sheet 20, still adhering to each other, are advanced towards separating mechanism with the leading edge of sheet 20 slightly in advance of sheet 19 (Fig. 1, not shown). This leading edge, passing over a driven roller 10, engages the lever of a microswitch 22, and is at the same time guided down between plates 26, following the path of broken line 23. A presser bar 12 at the end of an arm 15, and an idler roller 11 at the end of an arm 16, are both pivoted on a shaft 13, and actuation of the microswitch energizes a solenoid to pivot both these arms clockwise from the position of Fig. 1 (not shown) to that of Fig. 2. The presser bar engages transversely across the sheets, and bends them sharply. This bending, together with the rubbing action of the presser bar on the back surface of sheet 19, causes the latter to curl away from sheet 20 which is already gripped between rollers 10 and 11, now in contact. On further continuous advance of the sheets, sheet 19 curls back and passes between guide plates 24, along the path of broken line 25. A fixed blade 29 may assist the movement of sheet 19. When the trailing edge of sheet 20 leaves the microswitch lever, the solenoid is deenergized, and the parts return to their initial position. In the modified arrangement of Figs. (not shown) 3 and 4, the two sheets pass in contact between guide plates, one slightly in advance of the other as before. The leading sheet passes between a pair of rollers, and actuates a microswitch which causes the upper of the guide plates to bear against the roller and against sheet 19. This is caused to curl away upwards in the same way as before by the rubbing action of the guide plate.
