209, and indented subclasses, for systems wherein a periodic electric switch is provided in the supply circuit of the load device.
227, and indented subclasses, for systems wherein a condenser is connected in the supply circuit of the load device so that the discharge of the stored electrical energy in the condenser is applied to the load device, the condenser being connected in the load device circuit so as to be charged and discharged periodically.
291, and indented subclasses, for systems provided with means for regulating the current and/or voltage applied to the load device.
313, for systems wherein the system includes two or more load devices and is provided with an electric switch in the supply circuit of one of the load devices.
