Title: Improvements in or relating to control systems for electric winder motors
Inventor: FRIEDLANDER ERICH SIEGFRIED
IPC: B66C13/23
Filed: 1962-10-09
Abstract: 987,182. Control of motors. GENERAL ELECTRIC CO. Ltd. Sept. 27, 1963 [Oct. 9, 1962], No. 38201/62. Heading H2J. During decking operation, the pattern speed of a winder motor is corrected by a signal related to the load on the motor. Resistors 1-5 are sequentially inserted in a circuit producing a signal current for controlling the motor, the signal current being compared with the load current to determine whether a resistance-section inserted in the control circuit is to remain therein. A polarized relay 7 has winding 10 carrying the signal current which is fed to reactor winding 8 for correcting the control of the winder motor. The relay 7 also comprises winding 9 supplied with loaddependent current, the comparison between the two currents being modified by an acceleration responsive winding 12 and bias winding 13. Contact 27 is closed by a depth indicator or when the brake is disengaged, contact 28 being open if the winding 9 is predominant initially. Relay 14 is energized to insert resistor 1, and, if  winding 10 is energized sufficiently, contact 28 closes to energize relay 22 through a contact of time-delay relay 15. When energized, relay 22 disconnects the resistor 1 and is maintained by a self-holding contact. The energization of relay 14 initiates operation of relay 15 which, after a delay, closes the circuit of resistor 2 which will stay in circuit or be disconnected by relay 23 in accordance with the operation of relay 7. If, on operation of relay 14, the signal current had been insufficient to close contact 28, relay 22 would have remained deenergized to prevent disconnection of resistor 1 or any subsequent closure of contact 28. As the operation of relays 14-19 progresses, each resistor will be connected in parallel and either maintained in circuit or disconnected according to the operation of relay 7. When all the relays are energized, there will be a combination of resistors in parallel so that the signal current is just less than sufficient to close contact 28. This current is fixed in value by relays 22-26 and will correct the motor torque by means of winding 8. The resistors 1-5 have an ascending order of values, according to a binary notation. The relay 7 may be replaced by a magnetic amplifier, and the other relays by transistors. A contact 29 allows for adjustment of the motor starting torque.

Filed: 1961-10-25
Abstract: 1,035,185. Inverting. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Oct. 22, 1962 [Oct. 25, 1961]. No. 38227/61. Heading H2F. An inverter operating at a frequency f has a transformer, whose centre-tapped primary winding 11 forms with a capacitor 13 a parallel tuned circuit tuned to the frequency f, and has connected to each end of the primary winding N parallel circuits each having a controlled rectifier A, B, C or D, in series with another parallel circuit tuned to a frequency less than f/N. In the Figure, N = 2, and the pair of parallel circuits at each end have their capacitors combined. The rectifiers are triggered in sequence, and as the parallel circuit connected in series with each rectifier is capacitative at the frequency at which each rectifier operates, the rectifiers remain reverse biased, after being turned off, for longer than a half cycle of the output, so that the output frequency is not limited by the recovery time of the rectifiers.

Parisons from a magazine 29 drop through an opening 30 into a tunnel 28 heated by air blown over heating elements 35. The parisons are suspended by beads around their necks in openings 38 in the links of a conveyer 31 which is driven by sprockets 39 in synchronism with the carrier wheel 22. A parison is lifted out of the conveyer through an aperture 36 by radially extending a holder 26 from the lowermost arm 23 of the wheel 22. The parison neck is held by engagement over an annular seal on the holder 26 which is then retracted. The wheel is rotated to take the parison to the heating station 40 where the parisons reach the final blowing temperature. The holder is extended and retracted to pass the parison between a ring of infra-red radiators 103, Fig. 8, provided with reflectors 105. The speed is controlled to axial portions of the parison to different temperatures and the parison is rotated to obtain even heating circumferentially. The slidable member comprises a cylinder 63 containing a piston 90 for extending the stretch blow mandrel 92. Blowing air is supplied through a flexible conduit 93 from parts in the wheel hub 60 which are aligned with the conduit 93 at appropriate stations. The cylinder 63 is slidably moved through a guide 64 by a follower 67 which engages a groove 68 of a guide block 69 of a stationary drive means at appropriate stations. The guide block 69 constitutes the spindle nut of a spindle 70 which is rotated by a motor 73 to radially displace the cylinder 63 and the holder 26 attached thereto. The holder 26 is rotated by a motor 81 through gearing 83. After heating, the parison is carried to theblow mould 42 described more fully for Specification 1,530,659.

Abstract: 876,722. Filters. HIRS, G. Dec. 12, 1958, No. 40127/58. Class 46. [Also in Group XXXVII] When the pressure in a fixed cell 3 exceeds a certain value on account of clogging of that portion of filter fabric 25 then in position above a screen 53 mounted on a lower movable cell 4, pressure responsive control 60 is actuated. By this means inlet pump 56 is stopped, and liquid drains from cells 3 and 4 for a period governed by a timer, (not shown), also started by control 60. (A " cycle " timer, not shown, is also automatically started). At the end of the draining time a motor 22 is automatically started and it causes the movable cell 4 to be lowered by rotation of rods 8, to which the cell is secured, in nuts 9. Eventually a fixed limit-switch 62 is operated by a bracket 64 moving with the rods, stopping motor 22 and starting a fabric feed motor 40 and a timer, (not shown), governing the period of running of motor 40. Fabric 25 is thereby withdrawn from the lower of two shafts 26, passes between cells 3 and 4, and is discharged by lower shaft 36 (driven by motor 40) to a box 38. When the motor 40 is stopped by the stopping of its timer, motor 22 is again automatically started to raise cell 4 to its former position. Motor 22 is stopped upon operation of a limit switch 61 by a bracket 63. Finally at the end of the period governed by the above-mentioned " cycle " timer, the pump 56 is automatically re-started and filtering is resumed. Above cells 3 and 4, are two other cells 1 (fixed) and 2 (movable), cell 2 being moved at the same time as cell 4 and by the same mechanism. A corresponding (upper) roll of fabric 25, and (upper) discharge shaft 36 are provided. Specified liquids are mentioned.
