Title: Improvements in apparatus for controlling a sequence of operations
IPC: D06F39/00
Filed: 1945-02-02
Abstract: 633,054. Washing-machines. BRITISH THOMSON-HOUSTON CO., Ltd. Feb. 2, 1945, No. 2637. Convention date, Feb. 5, 1944. [Class 138 (ii)] [Also in Group XXXVII] An automatic washing-machine control, comprising a " program " disc 8 driven by a timemotor 16 for carrying out a series of operations in timed sequence, has means, effective during one of the operations, e.g. the washing operation, for interrupting the drive to the disc for a predetermined interval so that the duration of the operation is increased by that interval. The disc 8 has annular cams 9 for actuating, through balls 6, plungers 5 of switches 2 controlling the washing-machine, and is fast with an indicator dial 14. The drive to the disc is through a gear 15 and a friction clutch 8a which enables the disc to be adjusted by the dial. When the disc 8 reaches the operation whose duration can be extended, a sloping part 40 of a projection 41 on its rear face engages and rocks a pawl 33 which then arrests rotation of the disc by engaging. a shoulder 42 of the projection. Simultaneously, a pawl 34 turning with pawl 33 disengages a ratchet disc 20 which is thereupon driven by the gear 15, through a friction clutch 21, in place of the disc 8. The extension interval terminates when a projection 43 on the ratchet disc 20 reaches and rocks the pawl 34 so that the pawl 33 is freed from the disc 8 which then resumes its rotation. Adjustment of the interval is effected by turning a handle 26 which has a pin-and-slot connection with the ratchet disc 20 and teeth 39 for rocking the pawl 34 out of engagement with the teeth 38 of the ratchet disc whilst making the adjustment.

Filed: 1975-01-22
Abstract: 1487005 Inverting SIEMENS AG 22 Jan 1975 [22 Feb 1974] 2870/75 Heading H2F In an inverter comprising a pair of D.C. input terminals 2, 3 across which are connected a pair of main controlled rectifiers 7, 8 which have freewheeling circuits 13, 14 and commutating capacitor 15, commutating inductor 12 and commutating controlled rectifiers 17, 18, the commutating capacitor 15 is charged from a further D.C. source 21 by means of a further controlled rectifier 20 and resistor 19, and has a further controlled rectifier 24 arranged to be turned on so as to prevent the voltage across capacitor 15 exceeding predetermined limits and so discharging it into the first D.C. input terminals 2, 3. The invention is applicable to an inverter 1 supplied from a variable D.C. source which may take the form of a bridge 5 of controlled rectifiers or of a chopper. Commutating capacitor 15 is initially charged from a constant voltage source 21 by turning on thyristor 20. Commutating thyristors 17, 18 are respectively turned on so as to turn off the main thyristors 7, 8. The voltage at the lower terminal 16 of capacitor 15 is monitored at 25 and compared with the voltage at 21. When the capacitor 15 is charged excessively, a Zener diode or Schottky diode (Fig. 2, not shown) breaks down, turning on an auxiliary thyristor which is coupled via a transformer to the gate of thyristor 24, which thus discharges capacitor 15 into the main D.C. source 5. In Fig. 4 (not shown), further circuits 20 ... 24 are included to charge capacitor 15 from an auxiliary D.C. supply of opposite polarity and to prevent it assuming an excess voltage with that polarity.
