(under subclass 69) Subject matter wherein the motor is supplied from a source of current which is separate from the current supply for the discharge electrodes.
(1) Note. In most systems in this subclass the current and/or potential supplied by the auxiliary current source is controlled in response to a condition of the electric discharge to control the feed motor.
(2) Note. Continue the search in subclasses 31, 70, 72, 73 and 74 of this class.
SEE OR SEARCH THIS CLASS, SUBCLASS:
62, for discharge devices and systems under the class definition in which the initiation of the feeding of an electrode is dependent upon the speed of an electric motor, the motor being caused to operate in response to some characteristics, such as the voltage across the discharge electrode of the discharge device indicating improper inter-electrode spacing.
