Title: Improvements in or relating to regulating or controlling systems
Inventor: GEMMELL DAVID CHALMERS NICOL
IPC: G05B11/01
Filed: 1945-09-13
Abstract: 655,423. Centrifugal fans. ELECTROFLO METERS CO., Ltd. Sept. 13, 1945, No. 23625. [Class 110(i)] [Also in Groups XXXV and XXXVII] Apparatus for automatically regulating a variable quantity or condition comprises a first regulator member responsive directly to the magnitude of the quantity, and a second regulator member which is operatively interconnected with the first regulator member to operate when the latter reaches either limit of its working range, and extend these limits by an amount less than the total range, wherein the second regulator is varied by an auxiliary control device which also temporarily controls the response of the first regulator when the second regulator is operative, to prevent surges or incorrect values of the quantity, otherwise resulting from such operation. Combustion in a furnace 18 is controlled (i) by a damper 21 operated through a linkage by a slide rod 2 of a control mechanism (which may be of the kind described in Specification 463,326) [Group XXIX], actuated by the pressure in the combustion chamber and (ii) by an electric blower 19 having two-speed control gear 9. When the damper is closed, and the fan at low speed, a requirement for more furnace air causes the control mechanism to move the slide rod upwards to open the damper until at the limit of movement the projection 2b trips the holding switch 7 and closes the switch 3 to energize the relay 13 through a thermal time delay relay 3a to operate after a time interval, switch the blower to high speed through the conductor 12, and energize the solenoid 6 to return the damper towards its closed position. The switch 3 is opened and holding switch 7 is tripped by the movement of the slide rod, releasing relay 13 and restoring control to the damper mechanism. while the blower remains at high speed. A fall in the air requirement moves the slide rod downwards to close the damper until at the limit of movement the projection 2b trips the holding switch 15 and closes the switch 16 to energize the relay 14 through a thermal time delay relay 16a, switching the blower to low speed through the conductor 8 and energizing the solenoid 11 to over-ride the control gear and open the damper. Upward movement of the slide rod opens the switch 16 and trips the holding switch 15 to release the relay 14, when control is restored to the damper mechanism while the blower remains at high speed. The blower may be multispeed or variable speed.
