Title: Electrical controllers
Inventor: SPRAGG ALBERT DAY
IPC: G05B11/01
Filed: 1955-06-24
Abstract: 817,053. Automatic temperature control systems. ETHER Ltd. June 4, 1956 [June 24, 1955], No. 18288/55. Class 38 (4). In a system for automatically controlling a variable arc arm moving in response to changes in the magnitude of the variable moves a vane to interrupt light falling on a photo-transistor so that a contact-making relay in circuit with the photo-transistor is operated to control the variable. As shown, a galvanometer 11 responsive to change in the value of a variable, e.g. furnace temperature as detected by a thermocouple connected to terminals 3, 3, moves an arm 2 carrying a vane 4 so that, at a predetermined value of the variable, light from a tungsten lamp 5 passing through a lens system 9 and falling on a photo-transistor 6 is interrupted at the focal point 10. This reduces the energization of a winding C<SP>1</SP> of a relay 11 so that a contact S<SP>1</SP> is changed over from the position shown, in which it caused operation of means (not shown) to raise the value of the variable, e.g. by supplying more fuel, to a position in which it causes reduction of the value of the variable. The differential of relay 11 is reduced by auxiliary windings C<SP>2</SP> and C3 acting in appropriate senses which are introduced by a relay contact S<SP>2</SP>. The effect of these windings is delayed by the self heating of negative temperature coefficient resistors R<SP>1</SP> and R<SP>2</SP> respectively and is adjustable by a rheostat VR3.
