Abstract

1347675 Control of D.C. motors BRITISH DOMESTIC APPLIANCES Ltd 10 June 1971 [10 June 1970] 28186/70 Addition to 1266691 Heading H2J [Also in Division G3] The washing machine control circuit of the Specification 1,266,691 now includes a further switch 81 which, when open, blocks a thyristor 2, to remove the power to motor 1, and when closed allows controlled triggering pulses to pass to thyristor 2. In the embodiment, with switch 81 closed, resistor 80 is connected to the positive rail 70, allowing thyristor 2 to be triggered on and controlled by transistor 19 in trigger circuit A. The base of transistor 19 receives a reference voltage from potentiometer P in resistance chain 78, P, 79, which is also connected to the positive rail 70 via switch 81, that is opened and closed by the machine programme.
