Abstract

515,663. Automatic control system. SOC. ANON. DE COMMENTRY FOURCHAMBAULT & DECAZEVILLE. May 4, 1938, No. 8808/39. Convention date, May 12, 1937. Divided out of 514,396, [Group XII]. [Class 38 (iv)] Fluid pressure.-Gases flowing from a tube T in a furnace wall actuate a member C whereby electric contact is made at A or B on variation of gas pressure in the furnace whereupon a relay I is actuated to cause a motor J to adjust the flue damper. The controlling switch may be adjusted by a sliding weight on a switch arm and the contacts A, B are adjustable. The relay may operate to control the primary or secondary air admitted to the furnace.
