Abstract

818,916. Fluid-pressure servomotor control systems. GARRETT CORPORATION. Jan. 24, 1956 [Jan. 31, 1955], No. 29372/56. Divided out of 818,915. Drawings to Specification. Class 135. A temperature control system for an enclosure comprises a first conduit extending from a source of heater air to sand enclosure, a second conduit extending from a source of cooled air to said enclosure, pressure responsive valve means in one of said conduits for controlling the flow of said air to said enclosure, a fluid pressure actuated control device for controlling said pressure responsive valve means by controlling the pressure admitted thereto from a source of fluid under pressure, and a controller mechanism in said enclosure exerting control over said fluid pressure actuated control device by controlling the fluid pressure to which said device is subjected, said mechanism including manually and thermostatically controllable pilot valve means adapted to control said control device and thereby control the temperature of the air in the enclosure manually or automatically. The subject-matter of this Specification is substantially the same as that described in Specification 818,915, but the claims differ.
