DEFINITION

Classification: 314/119

(under subclass 113) Subject matter provided with electromagnetically operated means for moving the electrode in the separating direction.

SEE OR SEARCH THIS CLASS, SUBCLASS:

3, and 4 and indented subclasses, for consumable-electrode discharge devices having three or more electrodes and electromagnetic-operated means for separating and feeding the electrodes, and having means for first initiating the discharge between two of the electrodes and maintaining the discharge between these electrodes until at least one of the electrodes is consumed or fails to maintain the discharge, the discharge then being shifted to another electrode or to other electrodes.

10, and indented subclasses, for consumable electrode discharge devices having electromagnetic operated means for separating and feeding the electrodes and provided with means either to complete a shunt about the discharge device or some part thereof, such as the electromagnets, or to open the circuit of the discharge device or some part thereof when the consumable electrode has been consumed or when the discharge is extinguished.

23, and 24, for consumable-electrode discharge devices for separating and feeding the electrodes and provided with means operated by the electromagnets for removing and/or penetrating deposits of electrically nonconductive material on the ends of the electrodes.

31, for consumable-electrodes discharge devices having electromagnetically-operated means for separating and feeding the electrodes and designed for operation with polyphase alternating current.

33, and 36 and indented subclasses, for consumable electrode discharge devices having three or more electrodes and electromagnetically-operated means for separating and feeding the electrodes.

44, for consumable-electrode discharge devices having disk or plate electrodes and electromagnetic-operated means for separating and feeding the electrodes.

45, for consumable-electrode discharge devices having the electrodes either inclined or parallel with respect to each other and electromagnetic-operated means for separating and feeding the electrodes.

51, and indented subclasses, for consumable electrode discharge devices having at least two movable electrodes and electromagnetic-operated means for separating and feeding the electrodes.

66, for consumable-electrode discharge devices having electromagnetic means for separating the electrode and means other than the electromagnetic means which operate separately from the separating magnet for feeding the electrodes together, and subclass 67, where the feeding of the electrodes is operated by an electromagnet which operates separately from the separating magnet.

77, and 78, for consumable-electrode discharge devices having the electromagnetic-operated means for separating and feeding the electrode, the feeding mechanism being a positively acting mechanism.

91, and 94 and indented subclasses, for consumable electrode discharge devices provided with electromagnetic means for separating and controlling feeding of the electrodes and having an energy storing device, such as a spring or weight, for receiving energy from the electromagnet in one direction of motion of the electromagnet and for releasing energy in the other direction of motion of the electromagnet.

99, for consumable-electrode discharge devices having an electromagnetic means for separating and controlling feeding of the electrodes and provided with means for retarding either the motion of the electromagnetic and/or the movable electrode.
