Title: Improvements in or relating to apparatus for improving the tensile properties of steel wire
Inventor: MCFARLANE JAMES
IPC: C21D8/08
Filed: 1964-03-11
Abstract: <PICT:1114261/C6-C7/1> Apparatus for improving tensile properties of steel wire comprises one or more rotary members 11, 12, 21 around which wire is passed and means for passing a heating current from at least one rotary member, e.g. member 11 and 21, along a length of wire 23a, b under tension to effect its permanent elongation, the or each rotary member connected to the heating current supply circuit comprising a set of spaced commutator segments (see Figs.5 and 7, not shown) forming the wire engaging periphery 32 of the rotary member and one or more current carrying brushes 27-30 arranged to contact the segments at a circumferential position spaced from that portion of the periphery A, B, C, D on to or off which the length of wire being heated momentarily passes, so that current flows between each brush and only those segments connected to part of the periphery with which the wire is momentarily in pressure engagement.  Thus local martensite formation is avoided by precluding overheating due to sparking or arcing at the points A, B, C, D.  Preferably, the circumferential width of each brush does not exceed the circumferential length of each commutator segment, and the current supply path to each brush is of a different electrical resistance, a maximum circumferentially nearest to the points A, B, C, D and least furthest from such points so that current flow is uniform along the wire between the segments and the wire surface.  As shown, wire 23 initially passes around pre-tensioning reel 25, then around member 12 (not connected to the current supply circuit), then member 11, back to member 12 and so on prior to being heated, each member being provided with V grooves for wire advancement as described in Specification 969,191. Pulley 42 is a tension measuring device.  The length of heated wire 23b may be cooled before passing on to member 11 as described in Specification 748,357.

Abstract: 740,256. Automatic speed-control systems. GENERAL ELECTRIC CO., Ltd., and MAER, C. A. April 14, 1954 [April 16, 1953], No. 10470/53. Class 38 (4). [Also in Group XXXVII] A speed-setting lever 40 is guided for forward or reverse operation of a winder motor 10 by movement in paths 201, 202, which have a gate 203 between them. Each path extends from a full-speed position of the lever, through a zero-speed position, to a position providing dynamic braking at the end next to the gate 203. The current-supply to the motor is arranged to be disconnected when the lever is in a central position in the transverse gate. The motor 10 is of the induction type and has its stator windings supplied with three-phase current for driving in the forward or reverse directions, and with direct current for dynamic braking, the magnitude of this direct-current excitation, as well as the value of a hydraulicallyregulated liquid rotor resistance 13, being controlled as described in Specifications 738,310 and 740,257 so as to maintain the actual speed of the motor equal to the desired speed set by a potentiometer 47, the output voltage of which is compared with that derived from a tachometer generator 33 coupled to the motor. The lever 40 pivots about axis 41 and has a toothed sector 42 engaging rack 43 on which is mounted a slider 44. This slider co-operates with the potentiometer 47 which has tappings connected to studs symmetrically arranged on either side of a central position, and which is connected across a direct-current supply obtained from rectifier 48. When the lever 40 is moved away from the central " off " position in the middle of the gate 203, a slider 45 engages contacts 52 or 54 for energizing the reverse or forward contactor coils 53 or 55. A slider 46 engages contacts 56 or 57 for reversing the field-connections of the tachometer generator. Connections from the armature of the tachometer generator are made to the slider 44 and to an intermediate tapping 73 in the potentiometer 47 so that the voltage between the slider and tapping provides an indication of the desired speed of the motor. When the actual speed of the motor is greater than the desired speed a polarized relay 72 is arranged to energize the operating winding 69 of the dynamic braking contactor.
