Abstract: 775,996. Electric correspondence control systems. TINSLEY (INDUSTRIAL INSTRUMENTS), Ltd., STEGHART, F. L. F., and KERSHAW, P. L. July 14, 1955 [July 20, 1954], No. 21154/54. Class 40 (1). A variable force 125 or movement to be measured acts on one end of a beam 124 whose other end carries a vane 110 which produces corresponding alterations in the reactance of a coil 104 or capacitor in a tuned circuit connected to the emitter or base of a transistor 111, whereby a correspondingly variable output current is produced via an amplifier A which energizes a coil 123 attached to the beam 124 and movable in the field of a magnet 122 so that the beam is brought to rest, and the coil energizing current, shown on a meter 142, is indicative of the variable force. The change in transistor output may be increased by causing the beam to control the position of the moving vane of a differential condenser with one part in a base tuned circuit and the other in an emitter tuned circuit. In an embodiment the movement is derived from a diaphragm measuring the pressure difference of a venturi meter, and the amplified output current energizes the field winding of the magnet 122 as well as the moving coil 123 to balance the beam, and is hence proportional to the rate of flow past the venturi meter.
