Title: Improvements in or relating to the handling of stacked cards in data-processing
IPC: G06K13/10
Filed: 1962-06-19
Abstract: 956,329. Feeding sheets. SIEMENS & HALSKE A.G. June 19, 1962 [June 19, 1961], No. 23641/62. Heading B6B. Cards 2 are separated sequentially from the bottom of a stack in a magazine 1 by projections 7, 8 on rotating discs which engage each card within recesses 5, 6, respectively, to push the card forward past a gate member 4 and between a pair of feed rolls 17, 18. The cards can be of varying length, but the rectangular recesses 5, 6 are at a fixed distance from the leading edge. The discs are secured on a shaft 9 driven by a motor 10 through gearing 11 and a friction clutch 12. A cam 13 on the shaft 9 rocks a pivoted lever 14 carrying the idler roller 17 to raise the latter to allow a card to be placed thereunder; when the roller 17 descends the card is pressed on to the driven roller 18 and extracted from the stack. Means to ensure that a further card can only be extracted from the stack when the preceding one has been forwarded, comprises a lever 20, pivoted at 21, with a bent forward portion 20b which is urged upwardly by a spring 22 against the preceding card; in this position, a tooth 20a on the lever engages a ledge 19a on a disc 19 secured to the shaft 9 and stops rotation of the latter until the preceding card is clear of the bent portion 20b of the lever 20. The portion 20b is depressed to allow a further card to be separated, by means of a projection 19b on the disc which engages an arm 20c integral with the lever 20. Each card 2 is engaged by a feed disc 29 in a unit 32, which may be a card-punching or card-reading unit, and a set of contact springs 28 actuated by this disc imparts current impulses for controlling an electromagnet 27. The shaft 18a of the feed roller 18 carries a toothed wheel 24, and is driven from the motor 10 through the gearing 11 and a friction clutch 23, and the rotation of the shaft 18a is controlled by a pawl 25 adapted to engage the teeth on the wheel 24. The pawl 25 forms part of the armature 26 of the electromagnet 27, so that the mean rate of speed of the cards 2 is controlled by the disc 29 in the unit 32. The card separator is embodied in a separate unit 31 provided with hooks 33, 34 which engage in eyes 35, 36, respectively; of the unit 32, and the units are so positioned that each card 2 has a slight curvature between the disc 29 and the feed rollers 17, 18.

Filed: 1927-09-10
Abstract: 278,337. Algrain, P. Sept. 30, 1926, [Convention date]. Adjusting and connecting bogies and centrally-pivoted and radial axles for steering.-In rail or road vehicles in which the radial trucks 2 are radiated for steering about their pivots 3 by lateral movement of a central truck 4, the movement of the central truck is imparted to the radial trucks by means of one or more rotatable shafts 9 connected to the laterally-sliding central truck by a crank arm 10 and a rod 12. The shaft 9 is arranged at any required distance from the longitudinal axis of the truck and its ends are connected by cranks 11 and rods 15 to the apices 8 of triangular frames 7 fixed to the radial trucks 2. The single crank and rod 10, 12 may be replaced by two cranks and rods symmetrically disposed with regard to the central transverse axis of the central truck. The apex 8 of each radial truck frame slides in guides 17 in the main frame 1. In a rail vehicle the. lateral movement of the central truck is of course caused by the rails when the vehicle is on a curve, but in a road vehicle the wheels of the central truck may be steered by the driver so as to cause this truck to slide laterally of the main frame and to cause the desired radial movement of the end trucks.

Title: Improvements relating to gas locks
Inventor: WARNER DENNIS ALAN
IPC: G21F7/005
Filed: 1964-06-10
Abstract: 1,106,455. Gas locks. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 3 June, 1965 [10 June, 1964], No. 24012/64. Heading F2P. A gas lock between the discharge end 13 of a furnace used for treating toxic, radioactive material and the interior of hood 32 which can be evacuated or purged at 40 comprises a composite rim member 25, 26 defining and opening 29, a closure member for closing said opening, first sealing means which includes an 0-ring 23 in the grooved rim member 25 co-operating with the face 26 of the closure member to form a primary gas seal when jack 17 is actuated, and secondary back-up sealing means formed by surfaces 21 and 30 which co-operate to form a subsidiary pressure seal when ring 25 is removed with the jack extended for replacement of the O-ring. In normal operation, a boat 51 containing radio-active material is pushed by a ram (not shown) on to a table 45 which is slidably mounted on rails 44 attached to the top of the closure member. Ram 17 is actuated to raise the closure member until its face 20 seats against the O-ring, guides 12, flexible connection 18 and closure spigot portion 22 ensuring correct alignment of the closure member. A pivoted link 49 also centralizes the table. The interior of the hood may then be increased to atmospheric pressure, the hood raised by a further jack 35, and the boat removed. If replacement of the 0-ring 23 is necessary, the ram 17 is maintained extended and the screws 27 uniformly unscrewed. The ring 25 is unseated by the upwards pressure of the jack and the secondary sealing surfaces cooperate to form a subsidiary pressure barrier until the 0-ring is replaced. 'This arrangement permits the primary seal to be replaced whilst maintaining the furnace outlet isolated from atmosphere. The 0-ring 23 may be alternatively disposed in a groove in the closure member face 20. Further 0-rings 28 and 38 seal the composite ring members and hood respectively.
