239.~ Transformer in the condenser load device circuit


DEFINITION

Classification: 315/239

(under subclass 227) Systems provided with a transformer, one of the windings of the transformer being in the circuit which includes both the condenser and the load device.

(1) Note. Where the load device is connected to the source of supply by means of a transformer, the load device being connected to the secondary of this transformer and there is no condenser connected in the circuit, other than in the primary circuit of the supply transformer, the patent is excluded from this subclass and will be found in the subclasses below, the primary circuit being considered only a source of pulsating or A. C. potential for the secondary circuit.

SEE OR SEARCH THIS CLASS, SUBCLASS:

223, for systems which include a transformer in the supply circuit of the load device, the primary circuit of the transformer including a periodic switch and a condenser.

276, and indented subclasses and the subclasses specified in the notes to the definition of those subclasses, for other systems under the class definition having a transformer in

the supply circuit of the load device.
