A cable stranding apparatus comprises two wheel sets 4, 5 that are spaced apart, and are mounted in separate forks 4', 5 that are rotated in synchronism. The elements to be stranded are drawn through a stationary nipple and then pass back and forth over the wheel sets 4, 5 whilst the forks 4', 5 are rotating, the space between the wheel sets acting as a store. When the store is full the resulting cable is run out again whilst fresh elements are drawn in, the forks rotating in the opposite direction during this next stage, and so on. The forks may be driven by individual synchronous motors, or by gearing coupled to a common motor. One of the forks may be movable towards and away from the other fork.

Abstract: 1,200,298. Forging. G.K.N. SCREWS & FASTENERS Ltd. 21 Sept., 1967 [9 Sept., 1966], No. 40271/66. Heading B3H. In the pressing of a workpiece such as a nut blank, bearing cup or a backward extrusion, at a plurality of die stations M, O, P, Fig. 2, the workpiece is transferred between stations by spring-biased gripping fingers 53 on an intermittently rotated turret 27 and is pushed out of the fingers into the die and subsequently returned to the fingers. The turret 27 carries twelve sets of spring-closed gripping fingers 53 with bevelled entry edges and is adjustably mounted on a drive plate 31, Fig. 1, connected by shear pin 36 to a driving member 35 having a tapered fit 37 with a drive spigot 38. The tapered parts 35, 38 are pressed together by a stud 40. Spigot 38 carries a pin 42 engaging a slipper block 43 secured to a plate 47 which is mounted on an indexing device 49 having a scroll cam driven from the main shaft of the press. The dies 19 are secured to a die plate 17 by studs 23 and clamping straps 20. The punches 109 are carried by a punch plate 79 reciprocable through ball guides 82 on a pair of posts 80. Each punch 109 is mounted in a punch holder 102 and is adjustable vertically by a wedge plate 87 actuated by a nut 89. The punch holder is adjustable horizontally about pivot 103 by screws (106), (107), Fig. 5 (not shown), and also radially in the direction X, Fig. 4 (not shown), by nut (99). The punch has thus universal adjustment. For forming nut blanks, hexagonal section workpieces formed by pressing or cropping, are fed into the transfer fingers 53 at a loading station L. They are then transferred to station M, pushed by the punch out of the fingers and into die 19a, and formed into a first shape, Figs. 9, 10 (not shown). An ejector rod 15a then pushes the workpieces out of the die and into the fingers 53 which transfer them first to intermediate station N and then to the next die station O. Between stations M and O the workpieces are turned end to end by engagement of a gear 72 on the finger housing 56, with a fixed rack 75; guide plates (77), (78) at station O ensure that the fingers are located correctly. At station O, the workpieces are pressed into the final outer shape, Figs. 11, 12 (not shown), and at the next station P, a central web is punched out of the bore, Figs. 13, 14 (not shown). The blanks are unloaded at station Q. A further set of workpieces are being processed simultaneously in a set of similar dies at the opposite side of the press, Fig. 2. In an alternative arrangement for a horizontal nut-forming machine, the turret rotates about a horizontal axis.

A type-carrier fluid-operated setting device comprises a piston 3 movable in a cylinder into which pressurized media is fed at both ends and from which their are a number of discharge passages 10 (only one of which is shown) corresponding in number to the number of types in a row or column on the type carrier and each controlled by a valve 11 which can be selectively opened, the piston 3 being formed so that it has extensions 29 on each face so as to progressively reduce the flow of fluid and deaccelerate the piston. The extensions may be conical, may be chamfered on one side or formed with a notch. Further passages 31 may be formed on each side of the position 31 so that, with the length of the piston being slightly less than the diameter of the apertures 10 the piston is accurately balanced in desired setting portion by the flow of fluid into the aperture 10. Rotative positioning is similarly arranged, Fig. 2 (not shown) with the apertures circularly arranged, the piston 16 projecting from a bush 17 keyed to the shaft 1 of the type carrier.

Title: Internal combustion engine ignition systems
IPC: F02P3/08
Filed: 1966-09-15
Abstract: 1,089,146. Ignition systems. GENERAL MOTORS CORPORATION. Sept.15, 1966 [Oct. 1965], No.41284/66. Heading F1B. An ignition system comprises a source of direct current 10, an inductor 44, a switching means 32 for connecting the source of direct current and the inductor, a capacitor 58, a charging circuit connecting the capacitor and the inductor for charging the capacitor from the inductor and a discharging circuit for the capacitor including a second switching means 48 and the primary winding 64 of an ignition coil and means connecting the charging circuit with the second switching means in such a manner that a reversal of current in the charging circuit triggers the second switching device to a conductive condition. When the breaker contacts 24 are closed a forward bias is applied to the transistor 32 which causes it to conduct. When the breaker contacts 24 open and transistor 32 turns off the circuit to the inductor 44 is broken. The energy stored in the inductor will now be transferred to the capacitor 58 through a circuit that includes resistor 46 and diodes 62 and 54 when all of the energy stored in the inductor 44 has been transferred to the capacitor 58 to charge the capacitor, the current in the circuit will attempt to reverse its direction by virtue of the voltage developed across the capacitor 58. This attempted reversal of current flow is blocked by diodes 54 and 62, however, and the reversed current therefore flows from the capacitor 58 through the primary 64 of the ignition coil 66, resistor 46 inductor 44 resistor 52 and then through the gate cathode circuit of the controlled rectifier 48. This biases the controlled rectifier 48 to a conductive condition and the capacitor 58 will now suddenly discharge through the primary winding 64 of the ignition coil 66. Modifications are described in the Specification with reference to Figs. 2 to 6 (not shown).
