Abstract: 1311310 Arc extinguishing in switches MERLIN GERIN 30 Dec 1970 [14 Jan 1970 2 June 1970] 61709/70 Heading H1N A circuit is interrupted by two series breaks 10, 12 opened within a given time of one another, one break 10 being shunted by rectifiers 14 and a thyristor 16 in series, the thyristor being triggered into conduction shortly before current zero in the half-cycle in which the rectifiers 14 are conductive. The thyristor need be rated only for the are voltage across break 10, the rectifiers 14 supporting the recovery voltage. The thyristor carries the arc current only for a short predetermined period. In operation the conduction of the thyristor effectively extends the current zero at break 10 which is thus fully deionized before the next half-cycle whereupon the rectifiers are non-conducting and the arc at break 12 is extinguished. The triggering circuit for the thyristor comprises a unijunction transistor oscillator 136 which is suppressed until a delayed version of the current waveform derived from a transformer 122 drops below a predetermined level. Supply voltage for the oscillator is derived from the rectifiers 14 and is therefore present only during an interruption and only on the correct half-cycle. The application of the supply is delayed by 150, 152 to prevent triggering at the beginning of the cycle. The breaks may be vacuum switches or SF 6  types, the contacts having a helicoidal structure to move the arc around. The current transformer may be omitted (Fig. 4, not shown). The two breaks may be formed by a single bridging contact (Fig. 5, not shown) the rectifiers 14 being connected to the bridge.

Abstract: 1,269,480. Remove bundles of sheets from a pile thereof. TSUBAKIMOTO CHAIN MFG. CO. Ltd. 19 Dec., 1969 [19 Dec., 1968; 24 Dec., 1968], No. 62154/69. Headings B8C and B8R. Apparatus for transferring a bundle A<SP>1</SP> of paper sheets from a pile A thereof on a lifter B and on to the table D of a packaging machine comprises a detecting means C which detects the level of the top of the pile A with respect to that of the table D to control upward movement of the lifter B, and an intermediate transfer means E which flattens the edge of the bundle adjacent the table so that it may be gripped by a clamp G and transferred to the table D. To compensate for undulations in the pile the detecting means C comprises three detectors 1a 1b, 1c each comprising a roller 5 carried by a pivoted arm 4 urged upwardly by contact with the pile A. Each arm 4 carries a cam 6 arranged to operate primary and secondary microswitches (2, 3, Fig. 4) in sequence, one or two of the rollers are arranged to run in the furrows of the undulation (which extend parallel to the direction of transference of the bundle), the arrangement being such that in normal operation all the primary switches must be operated to stop the lifter, initiate transfer of the bundle, and lift the detecting means C clear of the pile A. But, if any one of the secondary switches (3) is operated, the lifter is stopped and the detecting means C is lifted clear of the pile, thus indicating that the undulation in the pile is too great to allow transfer. The detectors 1a, 1b, 1c are mounted on a rod 7 so as to be adjustable longitudinally thereof, and the rod 7 is mounted on the main frame F of the machine by screw rods 10 which are interconnected by a chain 13 running round sprockets 12 and which can be rotated by a handle 14 to alter the height of the detectors for various bundle thicknesses. The rod 7 also supports an air cylinder 20 the piston 22 of which causes rotation of a further rod 18 which carries levers 19 supporting the arms 4. At commencement of operation the piston is extended to lower the levers 19 and hence the arms 4, the rotation of the rod 18 also causing closure of a switch 25 to activate the lifter B, and when all primary microswitches (2) (or one secondary microswitch (3)) are operated the piston 22 is retracted and the levers 19 are lifted to raise the arms 4 clear of the pile. The intermediate transfer means E comprises a pair of horizontal plates (28, 41, Fig. 7) abutting the table D and from which project stops (31) carrying microswitches (30). When a bundle of paper hits the stops (31), the microswitches (30) lower the stops (30) and raise the plate (41) to flatten the edge of the bundle.
