DEFINITION

Classification: 314/69

(under subclass 68) Subject matter wherein the means for supplying the power to move the electrodes is a rotary electric motor.

(1) Note. Most of the systems in this subclass and the indented subclasses have the motor connected in the circuit so as to be controlled in response to the condition of the electric discharge so that when the electrodes are spaced too far apart the motor will be rotated so as to feed the electrodes together.

(2) Note. Most of the systems in this subclass and the indented subclasses are also arranged to cause the motor to separate the electrodes in the event they are too close together.

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 a motor, the motor being caused to operate in response to some characteristic of the discharge device indicating improper inter-electrode spacing.
