92.~ Diverse-type load device or electrode substituted


DEFINITION

Classification: 315/92

(under subclass 88) Systems wherein the load device or electrode which is substituted for the first operated load device or electrode is of a diverse type.

(1) Note. To be considered diverse type load devices, or electrodes, the devices or electrodes must differ in some electrical characteristic. Mere difference in color or shape is not enough to make the load devices of different characteristics within the meaning of this subclass. Discharge devices containing different gases, or having different starting or operating characteristics, or a different number or types of electrodes are considered to be

of diverse types. Load devices having different impedances are considered to be of diverse types.

SEE OR SEARCH THIS CLASS, SUBCLASS:

87, for this subject matter where the system also includes automatically operating means to substitute a second source of current supply for the first operated source of current supply.

178, and the indented subclasses and the subclasses specified in the notes to the definition of those subclasses for other plural load device systems under the class definition provided with a plurality of load devices of diverse types.

1, and indented subclasses for similar systems if either the first operated device or the substituted device is a consumable electrode discharge device.
