摘要： 713,997. Interrupters. AKTIEBOLAGET SVENSKA FLAKTFABRIKEN. April 18, 1952 [June 8, 1951], No. 9837/52. Class 38(5) [Also in Group XXXV] A variable on-off control comprises a continuously rotating roller cam 1driven by a motor 2 and co-acting with a cam-follower 3 to operate contacts 7, 8. The ratio of the " on " to the " off " time of the contacts is varied by moving the follower 3 parallel to the axis of the roller-cam as by a nut and screw drive 4, 5. As shown, while the camfollower 3 is co-acting with cam surface A contact 7 controls a heater 15 (through a relay 9). When the follower is moved along the roller to co-act with surface B the nut 5 engages contact arm a to energize a relay 16 (which holds over contact arm b and contact 18), to energize a cooling compressor 11, 13, 14, and disconnect the heater relay. Thereafter contact 8 controls the cooling-compressor-unloading-valve 12. The Specification states that (i) movement of the cam-follower may be controlled by hand, or automatically by, e.g. a thermostat, (ii) the system may control any physical variable, e.g. the heating and cooling devices may be replaced by a humidifier and de-humidifier.
