Title: Photographic camera
IPC: G03B7/00
Filed: 1971-08-18
Abstract: 1321755 Collapsible cameras BALDA-WERKE PHOTOGRAPHISCHE GERATE UND KUNSTOFF R GRUTER KG 18 Aug 1971 [ 19 Aug 1970] 38743/71 Heading G2A The objective lens of a camera is carried in a retractable tube which can be moved outwards and inwards by actuating an operating element which extends through the external wall of the camera, the camera also having provision for range-setting. As shown, the lens 11 and a diaphragm opening 10 are mounted in an inner tube 8 which is securely attached to a partition 13 in an outer tube 9. The driving mechanism consists of a forked member 25 pivoted on a shaft 26 secured to the camera housing. The free ends of member 25 have outwardly bent lugs 23,24 which engage in openings 21,22 in opposite sides of the tube 9 see also Fig. 2 (not shown). Two springs 27,28 on shaft 26 tend to urge member 25 anti-clockwise as seen in Fig. 1, so forcing tube 9, and hence the objective carrier, outwardly of the camera into its operative position. The two arms of member 25 are connected by a crossbar 29 to which is secured a press-button 30 which is readily accessible through an opening 33 in the front wall 34 of the camera. Crossbar 29 also has a locking edge 35. Rotatably mounted on a pin 41 is a latch member 36 having a nose 37 and a detent 40. The detent co-operates with a detent cone 42 which is spring mounted in a sleeve portion 44 on the camera housing (see also Figs. 2 and 3 not shown) Fig.1 shows the camera with the lens tube in the extended (operative) position. If the button 30 is now pressed in the direction of the arrow A, member 25 is pivoted clockwise and the lens tube is retracted into the camera. At the same time the locking edge 35 is locked by the nose 37 of latch member 36. In order to extend the lens tube back into the operative position, so as to make an exposure, the button 30 is pressed again. This time a further nose 38 on latch member 36 causes the latch member to pivot anti-clockwise so that it is forced past the spring detent 42 and takes up the position of Fig. 3(not shown). At the same time nose 37 moves free of locking edge 35. If button 30 is now released, the spring-driven forked member 25 pushes the lens tube out again to the operative position of Fig.1. Range-setting is effected by turning an external setting ring 57. This engages by means of gearing 55, 56 with a cam ring 50 which controls longitudinal adjustment of the lens tube.

IPC: B26F1/24
Filed: 1963-10-16
Abstract: 1,121,901. Making perforated films; perforating sheet material. T. J. SMITH & NEPHEW Ltd. 15 Jan., 1965 [16 Oct., 1963], No. 40871/63. Headings B4B and B5A. Perforated sheet material is formed by passing the sheet between two contra-rotating rollers each of which carries ridges which co-operate only at certain points as the rollers rotate. In the embodiment illustrated in Figure 2 (not shown), the rollers carry helical ridges (17, 18) of the same hand. Alternatively both rollers may carry zig-zag ridges or one roller may have circumferential or helical grooves and the other axial grooves. The sheet may be freshly made and in the plastic state or may be plasticized either by direct heating prior to perforation or by heating the rollers during the perforation. In this ease if the sheet is sufficiently thick and the ridges sufficiently high a series of grooves are impressed on each surface of the sheet, the perforations occurring where the grooves cross over. Alternatively the sheet and rollers may be cold and the sheet sufficiently thin so that no grooves will be impressed upon its surface during the perforation. The rollers may rotate at the same speed or the speeds may differ slightly.
