Title: Coil winding apparatus
Inventor: LIGHTNER ROBERT BRUCE
IPC: H01F41/06
Filed: 1968-05-24
Abstract: 1,221,483. Making coils; winding; welding by pressure; shearing and perforating. REYNOLDS METALS CO. 24 May, 1968 [8 June, 1967], No. 24862/68. Headings B3A, B3E, B3R and B3W. [Also in Division F2] A coil winding apparatus similar to that described in Specification 1,072,078, has sensing means 170 for sensing movement of an inner end portion 40 of the material forming the coil and control means for ensuring that an outer end portion 41 is precisely positioned relative to the inner end portion 40. The strip conductor 37 is wound on to a core positioned on a mandrel 52 which is engaged by clutch means 171 with a drive shaft 58. A cam plate 190, through which the drive shaft 58 extends, is normally maintained stationary during rotation of the shaft 58 by a yieldable tip 206 thereon engaging a fixed stop 212. When a predetermined number of revolutions of the inner electrical lead 40 has been sensed by the device 170, a valve 230 is energized causing a piston-rod 217 to be extended, whereupon a sleeve 220 on the end of the shaft 58 is moved forward against the action of a spring 228 to couple the cam plate 190 with a flange 184 fixed to the drive shaft 58. Upon further rotation of the drive shaft 58, the cam plate 190 coupled thereto, actuates a switch 193 which stops the drive motor 172 and actuates a valve 234 to move a friction brake 177 into engagement with a friction wheel 176 fixed to the shaft 58. With the shaft 58 stationary, an outer electrical lead 41 and an inner lead 40 for the succeeding coil are cold welded to the strip 37 by dies (85, 86) (Fig. 4, not shown). After welding, the shaft 58 is jog rotated to complete the winding operation with the outer lead 41 precisely positioned. If the strip thickness 37 varies causing incorrect positioning of the outer lead 41, the switch 193 may be automatically adjusted in position depending on the coil diameter to ensure correct relative positioning of the leads 40, 41. The coil 37 being formed is engaged by a roller 241 which is connected to a rod 248 carrying a rack which engages a pinion fixed on a shaft 252. As the rack is moved in response to the coil diameter, the shaft 252 is rotated to rotate the switch support bracket 195A. The apparatus is similar to that disclosed in Specification 1,072,078 except that after winding, the mandrel 52 is indexed to a discharge station (57) (Fig. 3, not shown). A pair of stripping members (61) are pivoted by a cylinder (64) to clamp the coil whilst the mandrel 52 is retracted, whereupon the coil is unclamped and dropped on to a discharge shoot (65).

Title: Improvements relating to the control of electric motors driving planers and the like
IPC: B23Q15/007
Filed: 1919-10-14
Abstract: 156,343. Gowan, S., Miller, L., and Metropolitan-Vickers Electrical Co., Ltd. Oct. 14, 1919. Electric braking.-In an electric motor for driving a planing or like reciprocating machine, a dynamic braking-circuit is provided which includes a part or the whole of the series field windings and is characterized by the feature that the braking-current is caused to flow through the field windings in the same direction as the normal motor-driving current. During the cutting stroke, the switch 17 is closed on the contact 15 to complete a circuit through a coil 13 which closes the forward contacts 9 and 10, and the supply current flows through contact 9, armature 5, contact 10, and through the field windings 6, 7. In its passage it energizes a coil 30 to close a switch 26. A switch 21 is arranged to be open when the reverse contacts 11 and 12 are closed, and a switch 28 is open when the contacts 9 and 10 are closed and vice versa. No braking-current can therefore flow during this period. At the end of the cutting-stroke, the switch 17 is automatically thrown over by a tappet on to the contact 16, thereby deenergizing the coil 13, opening the contacts 9, 10, and closing the switch 23. The braking-current then flows from the armature 5 through braking- resistance 27, switch 28, coil 29, the part 7 of the field-winding switch 26, contact 21, and braking resistance 20, back to the armature. The switch 21 remains closed so long as the braking-current through the coil 22 (which acts in opposition to the coil 14) exceeds a predetermined value. As the motor slows down to this point, the contacts 11 and 12 are closed by the coil 14 to reverse the supply current and the switch 21 opens the braking circuit.. At the end of the next traverse, the braking-current flows from the armature 5 through resistances 20, switches 21 and 24, field winding 6, switch 28, and braking-resistance 27 back to the armature. The switch 24 is closed bv a coil 31 and a holding-coil 23, whilst the switch 26 is similarly served by coils 30 and 25. The field windings are normally shunted either by the upper or lower branches of the braking circuit, but as the resistances 20, 27 are large, the supply current is not detrimentally affected. Additional switches may however be provided to avoid this shunting. In a modified form, the braking circuit is arranged so that the braking- current traverses both of the field windings 6 and 7.

Addition to 254,162, [Class 7 (iii), Internal-combustion engines, Carburetting apparatus &c. for], and 359,114. [Class 7 (iii).] Specification 359,114 describes a self-feeding carburetter in which the air space of the float chamber e is connected to the throat of a Venturi b surrounding an auxiliary choke tube c into which the fuel nozzle f discharges, air and mixture throttles h, n being interconnected by a link k. According to the invention, the connection between the throttles is such that the rate of increase of opening of the air throttle is greater than that of the mixture throttle, both valves reaching the fully closed and fully open positions simultaneously. This may be effected by so connecting the link k to the throttle-actuating levers i, m that, in the closed position of the valves, the angle alpha between the link and air-valve lever i is smaller than that # between the link and throttlevalve lever m. The desired openings of the valves may also be obtained by (1) employing levers of different lengths, (2) inserting resilient connections between the throttles, (3) cam control, (4) different relative positions of the throttles, and (5) employing valves of different diameters.
