Title: Manufacture of punch card strip
IPC: B31D1/00
Filed: 1965-05-06
Abstract: 1,101,606. Stationery. F. RUESCH, [trading as FERD RUESCH, MASCHINEN-UND WAAGEN FABRIK]. 6 May, 1965 [6 May, 1964], No. 19141/65. Heading B6A. A long strip or web of paper from which record cards can be punched, having the long fibres or grain of the paper in the cards transverse to the length of the strip, is made by joining together sheets cut from a paper web. The record cards punched from the strip are rectangular and have the grain lying parallel to their longer edges. As shown, rectangular sheets 1 in a stack have been cut transversely from a web wherein the grain lies in the longitudinal direction of the web, and each sheet, such as 1a, has a length in the direction of grain slightly greater than the length of a punch card, and a width transverse to the grain greater than one card, and preferably greater than two punch cards. The sheets are separated sequentially from the stack, and fed by grippers 6, 7 on belts 4, 5, through a device 8 where an edge stripe 9 of adhesive is applied, and are brought to rest by stops 10, 11. A reciprocating feeder 14 pushes the sheets step-by-step in a direction at rightangles to their previous movement through a sheet-joiner 15, 16 towards feed rollers 12, 13. As shown, the sheets 1e, 1d have been joined together by the adhesive stripes, and the registered sheet 1c is about to be joined to the sheet 1d, to form a strip from which the record cards (shown in dot-dash lines) are subsequently punched. The joins in the strip always lie between two adjacent cards, and the strip, after passing through various punching and printing units, can be folded in zig-zag fashion. In a complete apparatus (Fig. 2), comprising a sheet supplier (17), sheet feeder (18), stop (19), sheet feeder (20), and sheet joiner (22), the strip of joined sheets passes through punching and printing units (24, 27), a numbering device (29), and a folding device (30).

Title: Improvements in electric plug and socket couplings
IPC: H01R13/642
Filed: 1952-07-29
Abstract: 718,749. Air-blast switches; switches held set and freed mechanically. MARECHAL, A. July 29, 1952 [July 30, 1951; July 23, 1952], No. 19161/52. Class 38(5) [Also in Group XXXVI] The plug and socket parts of a two-part coupling for use as a switch comprise respectively, interfitting casings 4, 3. Fig. 3, housing contact carriers 7, 5 and carrying diametrically opposite bayonet locking means. The plug contacts each comprise a silver contact 36 on a head 9 secured to a rod 35. Surrounding the contact 36 is an arcing sleeve 37 urged against the head 9 by a spring 38. In the detached position of the plug, the contacts are shrouded by a movable member 8 attached to a bellows in the casing 4 which is expanded by a spring 42. The socket contacts comprise silver contacts 32 adapted to abut the plug contacts 36 and mounted on heads 6 carried by springs 33 in boxes 29 in member 5. Insertion of the plug takes place in two stages, this being permitted by the shape of the bayonet slots 11 in casing 3. Fig. 10. First, a straight-forward movement of the plug followed by a rotational movement brings bayonet studs on casing 4 into notches 11a in the bayonet slots. The plug is then in the position shown in Fig. 3 with the contacts still out of engagement. A further straight-forward movement of the plug causes the bellows to be compressed to expose contacts 36 which then engage contacts 32, the plug being locked in its final position by a spring-loaded hook 53 on the socket engaging a stud 59 on the plug. Release of the hook by pressure on a button 58 causes the spring 42 to separate the plug and socket rapidly, the plug returning to its intermediate position shown in Fig. 3 and the inrush of air into the bores 29 consequent upon the expansion of the bellows serving to assist in the extinction of arcs at the contacts. The plug may now be completely removed or left in its intermediate position until it is desired to close the circuit again.
