DEFINITION

Classification: 315/213

(under subclass 212) Systems wherein the system includes a

plurality of transformers, the secondaries of each of the transformers being connected to one or more of the load devices, the primaries of the transformers being connected to the periodic distributing switch means so that the primary circuits of the transformers are energized in timed sequence with respect to each other, thereby energizing the load devices in timed sequence with respect to each other.

SEE OR SEARCH THIS CLASS, SUBCLASS:

220, for single load device systems under subclass 209 provided with a plurality of transformers in the supply circuit of a load device, a periodic switch being included in the primary circuit of at least one transformer.

255, and indented subclass, for other plural load device plural transformer systems, each transformer secondary including a load device.
