(under subclass 185) Systems wherein the series connected load devices are discharge devices.
(1) Note. Where a single lamp or a single discharge device is the ultimate load device, and the system includes an additional lamp and/or discharge device in the circuit which is connected in the circuit so as to control and/or modify the current and/or potential supplied to such single ultimate load device, the patent is classified as a plural load device system, if (a) the controlling and/or modifying device is a lamp, or (b) the controlling and/or modifying device is limited in the claims to being a gas or vapor discharge device. Conversely, such a system is not classified as a plural load device system where the controlling and/or modifying device is claimed broadly as a discharge device even though it is disclosed as a gas or vapor discharge device.
The controlling and/or modifying device may be connected in the control circuit of the discharge device where the ultimate load device is a discharge control discharge device, and the same basis of classification is used as is set forth above.

36, for devices which include a plurality of discharge device units and an electrical circuit element structurally combined in a single unitary structure, the discharge devices being connected in electrical series relation.
180, and indented subclass, for systems under the class definition which include a plurality of series connected diverse type discharge device loads. 187, and indented subclass, for systems under subclass 185 provided with a plurality of discharge device loads and having a condenser connected in shunt to at least one of the load devices.
324, and indented subclass, and the subclasses referred to in the notes to those subclasses, for other plural discharge device load systems under the class definition.
