Abstract: 798,011. Gas blast switches. ENGLISH ELECTRIC CO., Ltd. Aug. 16, 1955 [Aug. 19, 1954], No. 24160/54. Class 38 (5). In a gas blast switch, the valve 14 controlling the gas blast is caused to open by the initial reverse movement of the interrupter contact 16, 17 during the opening operation of the switch, the valve reclosing after a predetermined open period. In the arrangement shown, when an operating shaft 25 is turned, overset toggle links 24, 23 cause the moving contact 47 to make a slight initial upward movement. The contact 17 moves the contact 16 upwardly against the bias of a spring 18 so that a striker 34 on the end of the contact 16 opens a pilot valve 32 to admit compressed gas to the top of the valve 14. The valve 14 moves down to permit compressed gas to flow from the switch chamber through the hollow contact 16 and passage 29 to exhaust apertures 26. As the rotation of the shaft 25 proceeds, the contact 17 is moved down to open the contacts, the contact 16 being arrested by a shoulder 19 abutting a guide tube 13a. The pilot valve 32 is closed by a spring 37 with a delay provided by a damping piston 35. The valve 14 is then reclosed by the gas blast acting on its undersurface and the blast then ceases and the switch chamber remains under pressure. The contact 17 may then perform a further isolating movement. Specification 796,581 is referred to.

Title: Improvements in or relating to pile hoisting mechanism for sheet handling machines
IPC: B65H1/04
Filed: 1960-07-14
Abstract: 934,943. Feeding sheets. HARRIS-INTERTYPE CORPORATION. July 14, 1960 [July 27, 1959], No. 24529/60. Class 100 (1). [Also in Group XXIV] In a sheet-feeding mechanism in which a plate 15, Fig. 2, receives a pile of sheets thereon and is freely supported on a frame 16, Fig. 1, which is upwardly movable by cables 24 . . . 27 to maintain the top of the pile at a predetermined level and downwardly movable to receive a new pile of sheets and in which the plate is adjustable transversely relative to the frame when in its uppermost, i.e. sheet feeding position, if such adjustment is necessary, means are provided for automatically ensuring that the plate occupies a predetermined position relative to the frame when the frame is subsequently lowered to receive a new pile of sheets. The means comprise angle members 47, Fig. 5, welded to the under surface of the plate and to legs 17 projecting downwardly therefrom which members, as the plate and frame structure enters a recess 18 in the floor upon which the mechanism stands, coacts with angle cam members 47, Fig. 1, disposed in the recess adjacent each corner thereof. Such interengagement thrusts the plate to a position in the recess where it rests upon its legs 17 centrally relative to the frame 16 beneath it. The frame 16 comprises channel members 19 . . . 23 mounting rollers 28 upon which the plate 15 is transversely slidable. The plate legs 17 depend through the rollers 28 and relative skewing of plate and frame is prevented by rollers 29 which depend vertically from the plate and engage the inner walls of the frame members 19, 21. Any necessary transverse movement of the plate relative to the frame when the plate and frame structure is in sheetfeeding position is effected by a hand wheel 39, Fig. 6, turning a screw 40 within a nut 41, the nut and screw being longitudinally restrained by the plate and frame respectively. Interengagement of the threads of the nut and screw is through the intermediary of a circulating ball system which allows, as the members 46, 47 coact on the entry of the plate and frame structure into the recess 18, rotation of the screw 40 in the nut 41 solely through the longitudinal thrust exerted by the nut 41 as the plate moves relative to the frame. The slight relative vertical movement between the plate and frame as the structure comes to rest in the recess 18 is provided for by effecting the attachment of the screw 40 to the frame 16 through a U-shaped bracket 45. The frame is guided in its vertical movement through plates 30, 31 attached thereto moving in slots 32, 33, formed in frame members 10, 11 adjacent the machine handling the fed sheets. The slots are inclined inwardly of the recess at 35, thus guiding the falling frame to move to a central position therein. The cables 24 . . . 27 and ancillary pulley gear for moving the frame vertically are disposed such that the latter when above the recess 18 is biased to abut posts 36 adjacent the sheet-handling machine.
