Title: Improvements in or relating to high-speed forging
Inventor: WILSON GEORGE
IPC: B21J5/02
Filed: 1955-09-10
Abstract: 804,468. Forging; trimming. ENGLISH STEEL CORPORATION, Ltd. Aug. 31, 1956 [Sept. 10, 1955], No. 25935/55. Class 83 (4). A method of forming a metal article by hotworking in one heat comprises forging in a die 10, Fig. 1, from a heated metal billet 28, Fig. 3 (not shown), a blank 29, Fig. 5 (not shown), of predetermined volume with excess metal forming a flash 30, trimming off the flash, whereby the blank has substantially the same volume as the final article, and forging the blank to shape in a final die 11, Fig. 1, within which it is completely enclosed. In one embodiment, for forging a gear blank 37, Fig. 9 (not shown), the blank 29 formed by the dies 10, 15 has an upper boss 31 which facilitates its removal and transfer, and an annular locating rim 32. The blank is then transferred into the trimming die 12 where the flash 30 is severed by a punch 17. The blank is removed from the die through a side opening 25 and the flash is removed from the punch by a stripper-plate 21. The trimmed blank 29 is then inserted in the final die 11 where its rim 32 is located in an annular groove 33. An upper die 16 then presses the blank to final shape and an ejector 26, forming the die bottom, removes the finished article. The locating projection on the blank 29 may alternatively be a central boss, Fig. 10 (not shown). In another embodiment, Fig. 14, the trimming and final forging are performed in a single bottom die 51, by a top die 54 surrounded by a spring- biased stripper-plate 55. Other embodiments are described for forging a motor vehicle mainshaft flange 59, Fig. 22 (not shown), and a bevel gear blank, Fig. 30 (not shown). In these embodiments the blank of predetermined volume is produced in two forging steps.

Title: Improvements in traverse mechanism for reeling rope and the like
IPC: B65H54/28
Filed: 1956-08-24
Abstract: 839,474. Winding ropes etc.; traversing mechanisms. SYNCRO MACHINE CO. Aug. 24, 1956 [Aug. 24, 1955], No. 26002/56. Class 120(2) Traverse mechanism comprises a rotatably supported lead-screw shaft, means forming a guideway, a carriage movable on said guideway, and a driving connection between the shaft and the carriage, in combination with driving means for rotating the shaft in either direction comprising a power driven wobble plate, a pair of oppositely acting clutches having a driving connection with said shaft and connecting. means for selectively connecting said clutches to the wobble plate. In the arrangement shown sprocket wheel 66 is driven from any part of the winding machine and rotates the shaft 64. Pivoted on the shaft 64 is a wobble plate 80 which can be angularly adjusted by the knob 68 and the groove of the wobble plate engages pins 110 and 112 carried by plates 106 and 108 of a framework which carries housings 88 and 90 of a pair of one way clutches. Journalled in these housings is a shaft 92 and the housings form the driving portions of the clutches and drive the shaft 92 through the driven portions 96 and 98 keyed to the shaft. Rotation of the wobble plate therefore causes oscillation of the framework and in turn of shaft 92 through one or the other of the clutches. The shaft 92 drives, through bevel gears 94, 24, the lead-screw shaft 22 on which is mounted a nut 60 which carries the traversing guide carriage 52. The direction of rotation of shaft 92 and therefore the shaft 22 is determined by which clutch is in engagement and this is determined by latchs 130 and 132 which can be brought in and out of engagement with the respective notched rings 114, 116 of the clutches. The latches 130 and 132 are under the control of solenoids 122 and 124 and appropriate return springs and the solenoids are alternately energized by limit switches 134 and 136 at the ends of the traverse. The positions of the limit switches 134 and 136 can be adjusted so as to vary the length of traverse.

Abstract: 468,049. Controlling change - speed gearing. TAGLIASACCHI, A. Sept. 20, 1935, No. 26090. Void. Convention date, Sept. 22, 1934. [Class 80 (ii)] The ball gear shift lever 49, Fig. 5, of a motor vehicle is operated by a governor 1, Fig. 1, driven through a sprocket 8 from the road wheels. The shaft 3 of this governor drives a compressor of air which operates in a main shift servomotor 15 and in a cross shift servomotor 16, Fig. 2. A crank 13, Fig. 1, on the governor shaft 3 constantly works the piston, not shown, of the compressor which normally reciprocates idly. For compressed air to act, a lever 6, actuated by the governor, through trip mechanism 35, 30 causes a double valve 28 to move one way or the other so that air pressure builds up on one side or the other of a piston 17 so as to displace that piston and with it a bar 39 joined to the ball lever 49, Fig. 5. As the bar 39 makes its gear-changing stroke, a rack 19 which it carries turns a pinion 20 which through a crank 21 opens the engine clutch, not shown, and closes the throttle, during change. The ends of the cross-shift cylinder 16, Fig. 2, are connected to the ends of the main shift cylinder 15, Fig. 1, by ducts 58 which are normally closed by valves 59, but are opened between speeds II and III only by a cam 60 on the governor lever 6. The governor 1 is steadied by an oil dashpot 9.

Title: Improvements relating to pulse welding circuits
Inventor: BALCHIN NIGEL
IPC: B23K9/09
Filed: 1967-06-09
Abstract: 1,201,653. Supply systems for pulsed arcwelding apparatus. WELDING INSTITUTE. 5 June, 1968 [9 June, 1967], No. 26779/67. Headings H2F and H2H. [Also in Division H3] A load current. thyristor V1 supplying welding electrodes 10 for example with pulses of current, is turned on by a gating pulse (Fig. 2, not shown) and turned off by a commutating capacitor C when a commutating thyristor V2 is itself turned on by a second gating pulse, the commutating thyristor V2 being turned off when a transistor V3 is made to conduct by a third gating pulse which appears after the second gating pulse but before the next gating pulse to V1. This arrangement ensures that if V1 fails to turn off when V2 turns on, then V2 is reset in preparation for another attempt to be made when it next receives a gating pulse. An auxiliary power supply 13 charges capacitor C while V1 conducts so that upon conduction of V2 the capacitor C will drive the anode potential of V1 below its cathode potential due to the initial voltage across a resistor 15, which represents losses in the circuit. This auxiliary supply 13 is disconnected when V2 turns on, by application to the base of a transistor V4 of a turn-off pulse lasting for the duration of the second and third gating pulses. A diode V5 protects the transistor V3. Background D.C. to the welding electrodes is supplied either by a resistance (not shown) across V1, or by a separate D.C. supply across the electrodes and protected by a series diode; or by the modification of Fig. 3 (not shown) wherein the auxiliary supply and series transistor V4 are replaced by connection of the anode of V2. and the emitter of V3 via a resistance (21) to the main power source 11, the thyristor V1 in this case having a load resistor (20). In this circuit the transistor V3 is left conducting until V1 turns on again, so that first V2 and then V3 supply the background D.C. between periods of conduction of V1. Extra gating circuits may be included; the first to cut off the V1 gate pulse if V1 anode potential is less than V1 cathode potential; the second to supply the V3 gate pulse only if V2 anode is at low potential, to avoid overloading V3; the third to fire V2 if its anode potential is too high (65 V.), to protect V3 from excessive collector emitter voltages; and the fourth to inhibit the normal gate pulse to V2 if V2 anodecathode voltage is less than 55 V. to prevent ineffectual operation if, say, the capacitor C is not fully charged.
