(under subclass 276) Systems having means provided in the system so that the transformer may be connected in the system so as to function either (1) as a transformer for the current or voltage supplied to the load device, or (2) as merely an inductance in the supply circuit, the transformer being converted to an inductance by connecting one or both of the transformer coils in electrical series with the source of supply and the load device.
SEE OR SEARCH THIS CLASS, SUBCLASS:
258, and indented subclass, for plural load device systems having an inductance in the circuit and a pulsating or A. C. supply.
283, and indented subclasses, for other systems under subclass 246, provided with an inductance in the circuit.
