(under the class definition) Systems provided with a transformer connected between the source of supply and a load device for supplying electric current and/or potential to the load device, the system also including a load device connected in the primary circuit of the transformer.
(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.
