Patent GB-767003-A (GB)
Title: Improvements in or relating to control apparatus
IPC: G05D23/22
Filed: 1953-02-09
Abstract: 767,003. Automatic temperature control systems. FOSTER INSTRUMENT CO., Ltd., OUGHTON, H. G., and GURNEY, W. H. Feb. 9, 1954 [Feb. 9, 1953; July 22, 1953], Nos. 3586/53 and 20353/53. Class 38 (4). In a system for automatically maintaining a variable at a desired value, electric current is (a) cut off to lower the variable when the latter is above a predetermined value; (b) made intermittent to raise the variable when the latter is just below the predetermined variable; and (c) made continuous through a separate circuit when the variable is well below the predetermined value. In Fig. 1 a thermocouple (not shown) responsive to the temperature of an electrically heated furnace (not shown) is connected to terminals 1 and another thermocouple (not shown) responsive to the temperature of the furnace charge is connected to terminals 2. These thermocouples are alternately connected by switches 4 and 5 to a moving coil instrument 3. During the time that the thermocouple responsive to charge temperature is connected, moving coil instrument 3 is associated with apparatus (not shown) for indicating or recording temperature. During the time that the thermocouple responsive to furnace temperature is connected, a switch 15 is closed so that contacts 6, 7, 8 and 9 of moving coil instrument 3 are effective to control the energization of an electromagnet 19 for switching on the furnace heating. The furnace is started up daily by a time switch 13 which, when it closes, energizes a solenoid 28 of a mercury switch 27 from A.C. mains 11, 12. Mercury switch 27 then passes from the stable position shown to its other stable position and in so doing momentarily energizes a solenoid 25 of a mercury switch 20 which moves to its stable closed position to complete the circuit to electromagnet 19. This switches on the furnace, the temperature of which rises until, above the desired temperature, moving coil instrument 3 closes contacts 6, 7 to energize a solenoid 22 of a mercury switch 18 which moves to its stable off position to de-energize electromagnet 19. At the same time a solenoid 26 of mercury switch 20 is energized to open the latter. When furnace temperature falls to a value, just below the desired temperature, at which moving-coil instrument 3 closes contacts 6, 8, a solenoid 16 is energized to close mercury switch 18 so that electromagnet 19 is energized intermittently through a mercury switch 21 operated by an adjustable cam 23 associated with a continuously operating synchronous motor 29. Furnace temperature is thereby restored but if, e.g. due to reloading of the furnace, it should fall to such a low value that moving-coil instrument 3 closes contacts 6, 9 a solenoid 24 is energized to close mercury switch 20 so that electromagnet 19 is continuously energized. In a modification, mercury switch 21 operates through an electronic process timer having an adjustable resistance-capacity circuit to set the on/off period ratio and contact 9 is extended over a range of temperature sufficient to permit mercury switch 27 to be dispensed with.
