A common controller for two motors or two sets of motors comprises a drum 1 fixed to a shaft having a control handle, and a drum 2 mounted loosely on the shaft and resiliently coupled to the drum 1 by a spring which is biased to set the drums in given relative positions. Movement of the control handle about a transverse pin actuates contacts 12, 13, to alternative positions. For simultaneous control of the motors, a push button 25 occupies the position I and the control handle is lowered to close contacts 16, 17, so that the controller brushes 18, 18<SP>1</SP> are energized and the two drums moved together. Sequential control of the motors is obtained by depressing the pushbutton to the position 11 and raising the control handle to open contacts 16, 17, and close contacts 14, 15. The brush 18 is thus disconnected but the brush 18' is kept energized through contacts 37, 43, before contacts 40, 41, open, the coil of relay 32 being energized so that a solenoid 26 closes a lock 27 to prevent rotation of the drum 2. The control handle is now turned to a desired angular position and is lowered .to re-connect the contacts 16, 17, and to de-energize the relay 32 which opens contact 33 after a predetermined period to release the lock and allow the drum 2 to follow the movement of the drum 1.

Title: Method of and apparatus for sensing liquid levels
IPC: G01F23/24
Filed: 1966-03-09
Abstract: 1,100,774. Measuring liquid level. W. HOLZER. March 9, 1966 [April 3, 1965], No.10336/66. Headings G1H and G1N. The level of liquid in, e.g. a washing machine is indicated by differentiating the output signal from an externally heated, negative temperature coefficient resistor probe mounted in the machine wall, this output signal changing sharply when the liquid reaches the probe. The temperature sensitive resistance is connected in series with a fixed resistor to form a potential diverter the tapping point being connected to an amplifier (valve, transistor, or unspecified) through a capacitor. The output of the amplifier controls a relay through a gas discharge device to turn off the supply of liquids. The tapping point is also connected directly to the same, or a separate, amplifier to give a temperature signal. A second probe, near the bottom of the container similarly gives a "boil-dry" warning when the container is empty.
