[Classes 83 (ii) and 83 (iv)] Soldering.-In making an electric cartridge fuse, comprising an insulating tube containing one or more fusible elements and metal end caps fitting thereon, the ends of the fusible elements are soldered to the end caps by placing a plate over the end of the tube, bending thereover an end of the fusible element, placing thereover a thin piece of solder and then forcing on the end cap and heating the cap externally to melt the solder. The fuse wires 3, which are surrounded by arc quenching material retained in the ceramic tube 1 by asbestos pads, pass through holes 7 in a brass or other metal plate 6 placed against the end of the tube and are bent over at right angles at 8 so as to be in contact with the central portion of the plate. A thin disc of solder 9 is placed over the ends 8 and a brass or other metal cap 10, which is provided with vent and inspection holes and may be tinned internally, is forced over the end of the tube, which may be tapered. The caps may be applied by cold or hot plungers 11, which in the latter case serve also to melt the solder. The plate may be dished to receive the fuse wire, the extending rim 15, which is level with the outer end of the diameter of the wire protecting the end of the wire from damage when the caps are applied by the plungers. The rim is continued to form an inclined flange 14 so as to yield if the tube 1 is not quite of the required length so that after the caps have been forced on the tube the required overall dimensions of the cartridge fuse may be maintained. In another form, the plate, which is dished and flanged at 14, Fig. 4, is of D-shape, so that a single fuse wire 8 passes over the straight edge thereof. In a further form, a circular dished and flanged plate may be used with a wide slot extending from the outer edge radially inwards to a point somewhat beyond the adjacent edge of the bore of the tube.

Abstract: 643,644. Knitting-machines. MELLOR, BROMLEY, & CO., Ltd., and MONK, S. A. July 11, 1945, No. 17649. [Class 74 (ii)] In a knitting-machine, a member is driven to and fro with an amplitude dependent on the length of path of a flexible driving member between adjustable guides, over which the flexible member is traversed by a second driving member; and shogging means is provided for imparting to the flexible member, preparatory to each of successive traverses of the driven member, a linear displacement, in relation to the second driving member and guides, in the direction of the traverse. A carrier driving bar 8 is reciprocated by a reciprocating endless double chain 1, through a slider 12 on the chain and a coacting guide slot 11 formed by fingers 10 depending from a block 9 carried by the driving bar; the chain is reciprocated from the tie-bar 20, through a chain 19, sprocket 17, pinion 15, gear 16 and sprocket 7. To give " lead " to the bar 8, at the beginning of each traverse, the chain 1 is given a linear displacement, between successive traverses, by shifting sprockets 7, 7<SP>1</SP> bodily in one direction or the other. This is done by rocking the sprocket-carrying levers 13, 13<SP>1</SP> by means of a lead cam 21 rotating at half cam-shaft speed. In order that the carrier travel may be varied, pairs 2, 3 and 2<SP>1</SP>, 3<SP>1</SP> of the chain guiding sprockets are mounted on blocks 4, 4<SP>1</SP>, slidable on a guide 5 and adjustable towards and away from each other by the rack heads of the machine, so as to vary the length of the horizontal portion 1c of the chain 1. The carrier bar 8 is held stationary at each end of its draw (whilst the slider 12 is travelling up or down one of the vertical portions 1a, 1b of the chain path) by catches 29, 29<SP>1</SP>, which are engaged by one or other of latches 30, 30<SP>1</SP> on plungers 32, 321, raised and lowered by a cam 34 reciprocated by the tie-bar 20.
