(under the class definition) Systems having two or more load devices connected in electrical series relation with respect to each other.
SEE OR SEARCH THIS CLASS, SUBCLASS:
36, for devices having a plurality of discharge device units and an electrical circuit element structurally combined in a single unitary device, the discharge devices being connected in electrical series relation.
49, for devices having a filament lamp and a discharge device structurally combined in a single unitary structure, the lamp and discharge device being connected in electrical series relation.
66, for multiple filament lamps structurally combined with a circuit element, such as a switch, the filaments being adapted to be connected in electrical series relation.
96, and subclass 99 and indented subclass, for series connected cathodes or heaters.
122, where an automatic shunt or cut-out means is provided to open the circuit of, or to close a shunt about, the circuit of at least one of the series connected load devices when the load device fails to operate properly. 177, for systems provided with a load device in the secondary of a supply transformer, and another load device in the primary circuit of the supply transformer.
179, for the subject matter of this subclass where the series connected load devices are of diverse types.
256, for systems under the definition of subclass 363, wherein a transformer is connected in the supply circuit of two or more nonseries connected load devices, the primaries of the transformers being connected in electrical series relation with respect to each other.
