Title: Improvements in safety devices in wire stranding machines
IPC: D07B7/02
Filed: 1963-10-21
Abstract: 1,011,037. Cable stranding machinery. SYNCRO MACHINE CO. Oct. 21,1963 [June 24, 1963], No. 41515/63. Heading D1T. A wire stranding machine of the type having a series of spools of wire mounted in stationary floating cradles which are pivotally supported inside a tubular housing is provided with safety controls which (i) prevent the driving motor from starting if all the spools are not locked in position (ii) stop the motor if any of the cradles tilts beyond a predetermined angular position (iii) stop the machine if any of the wires break. Each spool is supported in its respective cradle by bearing blocks which receive the projecting ends of the spool spindle and is locked into the bearings by a rod 44 which slides over the spindle when in position (Figs. 3 and 4 not shown). Each rod 44 in its locked position opens a switch 92; the switch 92, when closed (which is the case until the spool is locked by the rod 44) completes a circuit to earth from a thyratron 68 and thus causes switch contacts 72 in the motor circuit to open and render the circuit inoperative. A pair of inclined mercury switches 84, 86 is mounted on each cradle so that if the cradle tilts more than a predetermined amount a circuit is completed to earth through one or other of these switches, with the result that the motor contacts 72 are opened and the machine stopped. A bare conductor bar 60 extends along the length of the machine in a position to be contacted by a broken wire. The wires normally pass along guides on the outside of the tubular housing but if a break occurs are thrown outwardly against the bar 60. Again the circuit from the thyratron 68 is completed to earth and the contacts 72 open stopping the machine. The tubular housing of the machine is driven by means of annular gear rings which are bolted between the various sections of the housing.

[Also in Division F2] A steering column comprises two shaft parts 20, 21, one part 21, which bears or is arranged to bear a steering wheel 23, being telescopic relative to the other part 20 which is connectible to a steering mechanism of a vehicle, severable means 34 to prevent telescopic movement under normal axial loads on the part 21 but permit movement under heavier axial loads and means 6 providing frictional engagement between a movable and a fixed part 78 of the column and a deformable member 40 to absorb energy from the moving telescopic part. As shown in Fig. 1 the severable means comprises a flange 34 of a polyurethane or other plastics bush 26 which supports the column in and engages a supporting sleeve 28 and the deformable energy absorbing means comprises three spaced tapering grooves 40 in the sleeve 28 which distort or are distorted by the bush 26 on telescoping movement of the part 21. Alternatively the flutes be parallel, curved or helical. The end 28a of the sleeve 28 may be chamfered to provide a cutting edge (Fig. 9) and/or the flange 34 may be replaced by a series of radial projections engaging the complementary end of the sleeve 28. The energy absorbing means may comprise a tube with circumferential or helical convolutions arranged between the sleeve 28 and part 21 (Fig. 2, not shown) convolutions expanding frictionally engage the parts 21 and 28 when compressed axially.

The output of the transformer is connected to an input of a voltage comparator having two outputs each connected to an input of a respective one of the control winding amplifiers. The amplifier inputs are connected in series opposition. As shown in Fig. 2, the output voltage of a transformer 1 is rectified 20 and compared in a circuit 4 with a predetermined value defined by a bridge arrangement 30 including avalanche diodes 33, 34. The error signal output provided by the bridge 30 is supplied to the serially-connected inputs of intermediate amplifiers 7, 14 connected to a D.C. supply voltage source 19. The amplifier inputs are protected from transients by anti-parallel diodes 36, 37, and each amplifier includes a resistor 52 providing positive feedback. According to the polarity of the error signal, one or other of the amplifiers 7, 14 is made conductive, so that a corresponding power amplifier 10 or 17 energizes a control winding 11 or 18 on the transformer 1 in order to regulate the transformer output voltage. The windings 11, 18 are wound on separate elements of the transformer, and only one of the windings is energized at any given time, so that the power required to control the transformer is minimized.

Abstract: 1,067,173. Twisting. UNITED INDUSTRIAL TECHNOLOGISTS Ltd. Nov. 1, 1963 [Nov. 6, 1962], No. 41860/62. Heading B3E. A method of twisting a length of material comprises subjecting it to a combination of heat and of twisting torque at a localized point, so as to cause localized twisting, which is caused to traverse along the length of the material. A length of drill steel 24 is held at its ends by grips 11, 12, is heated by induction by a unit 22 on a carriage 21 and is cooled by water from a unit 23 on the carriage. As the grip 11 is rotated the carriage 21 is traversed by a lead screw 19 so that the steel 24 is twisted where it is heated. After the whole length 24 has been so twisted a ram 16 is actuated to urge the grip 12 away from the grip 11 and thus straighten the twisted length. In another embodiment, Fig. 2 (not shown), steel is heated throughout its length by resistance heating brought about by current supplied through rotary connections (32), (33). A twisting head comprising a disc (34) with a central aperture to match the cross-section of the drill steel is mounted on a carriage traversed by a lead screw 19 and is rotated by gearing (35) from a shaft (31) so as to twist the heated length of steel as it moves therealong. The twisted steel is cooled by the traversing cooling unit.
