Title: Improvement in a method of manufacturing zigzag-shaped wires for use in jointed wirework
IPC: B21F1/04
Filed: 1929-04-29
Abstract: 330,087. Schoetzau, J. April 29, 1929. Wire fabrics.-Coiled wire fabrics are made from zig-zag wires, produced by first rolling at points equidistant from each other to form knotlike points and then bending into zig-zag shape. S-shaped bends d are first formed on the wire by rolls A; intermediate bends e may also be formed at the same time or subsequently. The wire is then bent into zig-zag form as shown in Fig. 4. The limbs m, n, Fig. 8, of the zig-zags may be formed of unequal length so that the joints in the fabric are located approximately in a straight line corresponding with the direction of tension. The fabric may also consist of zig-zag wires in which the free space between adjacent joints of certain wires is a multiple of that of other wires as shown in Fig. 9.

Abstract: 1299636 Multiplex pulse signalling TOKYO KEIKI SEIZOSHO CO Ltd 20 March 1970 [22 March 1969] 13615/70 Heading H4L In a multichannel signal processing system, Figs. 1a, 1b, input signals from sources A1, A2, A N , are supplied sequentially via gates 2 to a signal processing device F and supplementary data signals from circuits C1, D, E, C2 are incorporated in a predetermined sequence with the signals A1 to A N , the channel gating pulses being provided by channel selecting circuits 4 which are connected in the form of a ring counter controlled by shift pulses on a conductor L7 from a control circuit C. In operation, the shift pulses cause circuits 4 of sources A1, A2 &c. to be successively energized to apply signals to circuit F to be processed under the control of auxiliary circuit C. Next the circuit 4 of auxiliary circuit C1 is energized and at the same time a timing pulse is applied to terminal T9 of circuit C so that data in a store 11 is supplied to terminal T10 of the circuit C thereby causing a signal to control the signal processor F via terminal T3. Subsequently several more circuits 4 of sources A will be energized sequentially and then, in coincidence with a timing pulse on line L9, data will be fed from store 13 of circuit D via gate 14 to terminal T15 and from store 12 to terminal T10 of the control circuit C. This is followed by the energization of several more circuits 4 of sources A and then the two circuits 4 in supplementary circuit E will be energized successively so that data from sources 16 and 17 will be transmitted successively to terminal T10 of circuit C. After the energization of several more circuits 4 of sources A the circuit 4 of supplementary circuit C2 is operated in the same manner as circuit C1 and the cycle of operations is repeated. In a modification, each circuit B associated with a signal source A includes also a store for related data which is gated at the same time as the signal but is fed to the control circuit C. In a further modification, the circuits B are provided with means for detecting if the input signal is abnormal, i.e. exceeds a predetermined level.

Abstract: 662,989. Linkwork. HARDING, J. P. May 23, 1950 [May 23, 1949], No. 13698/49. Class 80 (iii) [Also in Group XX] To give a fine and coarse control of the movement of a dissecting implement two pantographs are combined so that the copying point of the pantograph giving coarse control forms the fulcrum of the pantograph giving fine control, the copying point of the latter pantograph carrying the dissecting implement. As shown the coarse control pantograph A is pivoted at E and has as its copying point C the fulcrum of the fine control pantograph B, the copying point D of which carries the dissecting implement. In operation the implement is brought into the appropriate field of a viewing microscope by movement of the control point F of pantograph A. The point F is then held fixed and the implement adjusted by movement of the control point G of pantograph B. In the arrangement shown the point D moves in the same direction as the points F or G, but for use with a microscope giving an inverted image the pantographs may be arranged to produce a movement in the opposite direction. Alternatively the implement may be carried on the copying point of the coarse control pantograph, the control point of which forms the copying point of the fine control pantograph.

Abstract: 219,447. Jackson, W. J. Mellersh-, (American Chain Co., Inc.). May 28, 1923. Making chains; bending-dies; shearing-adjuncts. -Chains for anti-skid devices for vehicle wheels or other articles are reinforced by bending lengths of wire around the links. Lengths of chain'are laid in recesses in blocks 48, 49, Fig. 23, connected by links 50 to form a conveyer by which they are carried below a device having three sets of tools, arranged in staggered formation, for cutting off lengths of wire, bending these into a U-shape and then driving these over the central links of the chains and against the die blocks 49 so that they are bent as shown at 87. The wires 100, Fig. 1, are fed, through straightening rollers 4, by grippers 18, Fig. 7, which are closed by a toggle 20, slide 23, and groove 27 of a triple cam 12. The grippers 18 are carried by a slide 6 which is reciprocated by the cam 12 and a lever 8 adjustably connected at 13 to a link 14 so that the feed can be varied. Retrograde movement of the wires is prevented by similar cam- and-toggle-operated grippers. The ends of the wires, which abut against stops 47<a>, Fig. 19, are cut off by adjustable blades 96, bent over formers 93 by dies 94 and stripped by bridges 99. After each wire has been bent it is moved along its former by a lever 109, Fig. 20, oscillated by a spring 107 and the die 94. At each stroke of the die 94, a previously bent wire 102 is forced, by a plate 101, past a spring lever 111 along a passage 103 and clenched about a link immediately below it. The arms 79, Fig. 1, of the crank, which operates the dies 94, are formed as cams which, through rollers 80, levers 81 &c., move a frame 76 which has pins 86, Fig. 19, to engage holes in and correct the position of the conveyer and other pins 86<a> to engage and hold firmly the links being operated on. The conveyer is supported by guides 55, 57, and a roller 56 and is intermittently advanced by a gear 60 having teeth 62, Fig. 13, driven by two pins 64 carried by a bevel 63 in gear with another 67 driven by a chain 41, Fig. 1, from the main shaft 43. Both bevels have a surface 68, 69 without teeth so that the bevel 63 is rotated intermittently, the pins 64 preventing accidental movement of the conveyer. To prevent damage to the machine by misplaced chains or to the operator's hands, a safety guard 120, Fig. 1, is arranged just above the conveyer and is connected to a clutch &c. for stopping the machine. Any reinforced chains which do not fall from the conveyer are removed by stationary blades adapted to engage slots 117, Fig. 23, in the conveyer.
