(under subclass 327) Systems wherein the electric discharge device is provided with at least one principal anode and a principal cathode and an auxiliary discharge electrode with the auxiliary electrode mounted so as to physically contact one of the principal electrodes, at least; during the starting period of the discharge device, the auxiliary electrode being arranged in the circuit so that the discharge is initiated between the auxiliary electrode and one of the principal electrodes, the auxiliary discharge conditioning the discharge space between the principal electrodes so that a discharge between the principal electrodes can be established.

168, for this subject matter where the system includes a different type of current supply means for the auxiliary starting electrode from the type of current supply for the principal electrodes.
194, and indented subclasses, for this subject matter where the system includes means to shift the phase of the pulsating and/or alternating current in the auxiliary electrode circuit with respect to the phase of the current in the cathode-anode circuit of the load device.
203, for this subject matter where there is a discharge device or rectifier in the auxiliary electrode circuit.
234, for this subject matter where there is a condenser in the auxiliary electrode circuit. 261, and indented subclasses, for this subject matter where the discharge device is supplied with pulsating or alternating current.
335, and indented subclass, and the subclasses referred to in the notes to the definitions of those subclasses, for other systems under the class definition wherein the discharge device load device is provided with an auxiliary starting electrode.
