Abstract

494,166. Distant - control systems. GRASEBY, R. C. April 20, 1937, No. 11279. [Class 40 (i)] In a relay system of the kind described in Specification 469,611, for example, in which the actuation of a master switch (not shown) causes a current to flow along a pilot wire 4 to a relay 2 or 2a, thereby completing a circuit to a motor 9 controlling contacts in a lamp or other circuit 14 by means of a cam 12, the relay 2 or 2a is a polarized direct-current relay and when the motor starts the motor circuit is also maintained through contacts 10 operated by a cam 11. The motor continues to run until the contacts 10 are allowed by the cam 11 to open, whether or not the relay winding remains energized. The relay may be connected as shown between the pilot wire 4 and the neutral wire 5 of a three-phase system. The relays 2 and 2a are polarized in opposite directions so that either can be operated at will by sending the current along the pilot wire 4 in the appropriate direction.
