IPC: B29C33/00
Filed: 1967-11-13
Abstract: 1,229,218. Sheet forming. BRITISH PETROLEUM CO. Ltd. 29 Oct., 1968 [13 Nov., 1967], No. 51491/67. Heading B5A. Containers such as egg-boxes are made from, for example, foamed polystyrene sheet material by co-operating male and female mould halves, one of which carries retractable projections adapted to engage in recesses carried by the outer half to form undercuts in the finished article. As shown in the Figure, part 2 of the female mould 1, 2 is provided with four projections 6 (only one of which is shown) each of which is carried by the vertical arm of an L- shaped lever 7, the horizontal arm of which is attached to a common rod 8 rotatably mounted at either end 9 in the end wall of the mould. The horizontal arms of the levers 7 engage a vertically slidable striker plate 10 the upper edge of which projects beyond the upper surface of the mould. The striker plate is biased upwardly by a compression spring so that the levers are normally pivoted clockwise and the projections are in their withdrawn inoperative positions. The parts of the male half of the mould which co-operate with the projections each consist of a correspondingly shaped recess 24 the lower surface of which is defined by a swingable tongue 23 biased by counterweight 25 to its horizontal operative position. In operation the male half of the mould is forwarded into the female half and at the appropriate point in its stroke the plate 10 is depressed to cause the levers 7 to pivot anti-clockwise to bring the projections to their forward operative position within the recesses of the male mould half. After forming, as the male half is withdrawn, the striker plate rises under the action of the spring and the projections are again withdrawn. Also, the part of the article which is retained by the female half engaging the tongue 23 causes the tongue to pivot downwardly to the position shown in Fig. 5 thereby releasing the male half from the article to allow continued upward movement of the male half.

Abstract: 1288716 Automatic circuit breakers WESTINGHOUSE ELECTRIC CORP 19 April 1971 [6 Feb 1970] 20370/71 Heading H1N In a circuic breaker of the kind having an operating handle 65 movable to open and close contacts 21, 23 and which must be moved manually to a position beyond the open position to reset the latching mechanism after an automatic opening oration, a blocking device 115 is provided to prevent the resetting if, due to welding, the contacts remain closed. The circuit breaker is of the kind having a releasably latched trip lever 63 coupled by a toggle linkage 57, 59 to the contact assembly 35; the handle 65 is coupled by an overcentre tension spring 61 to the knee of the toggle. On overload a bimetal or electromagnetic trip 82 releases the latch 84 engaging lever 63 which thus moves upwards allowing spring 61 to collapse the toggle and open the contacts; the handle remains near the closed position until manually moved towards the open position, a projection 111 on the handle pushing the lever 63 back into engagement with the latch 84. If on tripping the contacts remain closed the arm 115 which is attached to the contact arm 35 projects into the path of lever 63 so that it cannot be re-engaged with latch 84. In another embodiment (Figs. 4-7, not shown) a hook pivoted on the lever 63 drops over a fixed latch bar when the lever 63 is released but is then pushed aside by a projection on the contact arm 35 as the contacts open. If the contacts remain welded closed the hook remains latched and the lever 63 cannot be moved towards its latched position.
