The cards bear a question or a word on one side and the answer or a picture illustrating the word on the reverse side and may be stacked in the rear compartment in their reverse or obverse positions. The box 10 is divided by partitions 15, 17 into compartments 16, 18, 19, the first forming a receptacle for spare cards and the others the front and rear compartments above referred to. The feeding-means comprises rubber or rubber-covered rollers 24 mounted on a transverse shaft 25 and operable by a handle 127. The front compartment 18 is provided with a sliding cover 22, formed with an extension 32 lying between the rollers to aid in holding the cards, when moved upwardly, in contact therewith. The upper ends of the cards are held in contact with the rollers by a spring-pressed follower 27 mounted on a bar 28, which slides in a groove in the bottom of the box. Rotation of the rollers causes the rearmost card to be fed upwards to the position indicated in dotted lines in Fig. 1, where it is held by the co-operation of the rollers and the cover 22. Further rotation of the rollers causes the card to fall upon a table 33, Figs. 1 and 2, which is mounted on a transverse rod 34 operated by a handle 35, the table being normally held in a downwardly and rearwardly inclined position against a stop 37 by a spring 36. By depressing the handle 35 the table is tilted to deposit the card against a partition 39 in the compartment 19 in the reverse position. In order to show only the obverse faces of a set of cards, an inclined board 41, Fig. 7, is mounted in the rear compartment between the base of the partition 17 and the upper end of the table 33, a lip 47 being stamped out of the board 41 against which the table bears.

Filed: 1968-04-18
Abstract: 1,224,637. Shearing. KARTRIDGE PAK CO. 18 April, 1968 [6 July, 1967], No.18317/68. Heading B3W. [Also in Divisions B4-B5, B6 and B8]  An apparatus for making U-shaped staples from a length of and for applying the staples to a gathered sausage casing or bag neck comprises means to feed a supply of wire-like material W under a staple forming portion 16 of a punch and means to transfer the former staple to a position underneath a staple applying portion 26 of the punch, and means to reciprocate the punch so as to apply and clinch a staple F and simultaneously to form a staple for subsequent application. The operator places an object to be fastened across spring-loaded plates 38, 38<SP>1</SP>, Fig. 5, and then closes a gate 31 over the object. A trip rod 35 is thereby lowered, connecting compressed air to a cylinder 17<SP>1</SP>, Fig. 1, so that a punch 12 is forced downwards. The punch 12 drives a previously-formed staple F downward to be clinched about material held over an anvil 29 while a length of wire for the succeeding staple is cut and formed on a block 15. The operator allows the gate 31 to spring open, thereby retracting the piston 17 and setting into operation wire feed mechanism 51. Plates 38, 38<SP>1</SP> rise to reject the completed package. The punch 12 comprises a staple former 16, Fig. 7, and a clinching portion 26 so that as staple former 16 descends to cut the wire W with an edge 64 and bend it with edges 25, portion 26 descends to clinch a staple F. A spring-loaded pusher 66 is cammed out of the way of staple former 16 by projections 70, 70<SP>1</SP> of the former. As the punch ascends, a plate 72 beneath which the wire was fed and formed, strips the newly formed staple from the punch. When the punch 12 regains its uppermost position, the pusher 66 pushes the new staple into the path of the punch, ready for the next stapling operation. The wire W may be round or flat wire stock of other bendable material, e.g. a stiff plastics or a metal and plastics combination.

Patent GB-1437863-A (GB)
Title: Object detecting systems using radiation sensors
IPC: G08B13/183
Filed: 1974-04-26
Abstract: 1437863 Light curtain monitoring systems ELECTRONICS CORP OF AMERICA 26 April 1974 [21 May 1973] 18375/74 Heading G1A [Also in Division G4] In a light curtain system of the kind in which an area is monitored by a set of optical channels each comprising a light source and detector, the channels are electrically inter-connected so that operation of the source in one channel gates the detector of the next channel after a suitable delay and also terminates the output of the detector of the previous channel. The purpose of using a channel to electrically control its adjacent channels is to permit wide angle sources and detectors to be used, the inter-connections being such that even if a source illuminates several detectors in other channels, only the detector in its own channel is gated on at that time and can respond. Fig. 1 shows four channels, one in dotted lines; the latter comprises source 10-1 driven by AND gate 22-1, a detector 12-1 which drives an AND gate 36-1, a bi-stable flip-flop 38-1 driven by the AND gate 36-1, and a delay unit 30-1 driven with the source by AND gate 22-1. The channels are controlled by a strobe 20 which is connected to the AND gates driving the sources. Suppose that the top channel of Fig. 1 is in the process of emitting light; its detector 12-4 activates AND gate 36-4 and hence flip-flop 38-4 to drive the AND gate 22-1 of the next channel on line 24-1. When the next strobe pulse arrives this activates the AND gate 22-1 (with the signal on line 24-1) to drive source 10-1. The AND gate 22-1 also resets flip-flop 38-4 on line 26-1, thus terminating the input on line 24-1; the source 10-1 therefore emits a light pulse which ceases when the input on line 24-1 terminates. While the source 10-1 is driven a signal is passed to delay unit 30-1. The light pulse strikes detector 12-1 whose AND gate 36-1 has been enabled by a pulse received from the delay unit 30-4 of the channel above, and the AND gate thus drives its flip-flop 38-1. This process repeats continuously along the channels, unless a channel light path is broken. At any given instant, one of the detector flip-  flops 38 is emitting a signal; these signals, apart from driving AND gates 22, are connected to OR gate 44. If a channel light path is interrupted the corresponding flip-flop signal vanishes, and the OR gate drives a relay 42 to operate an alarm 40 or to turn off a monitored machine. A starting circuit is described, Fig. 2 (not shown), for setting the flip-flop and the delay unit of a channel so that the next channel commences operation. Where many channels are used two or more can be started simultaneously provided they are far enough apart not to interfere optically. The channels can be arranged so that there are alternate sources and detectors on each side of the monitored area, or all the sources can be on one side and the detectors on the other.
