(under subclass 146) Devices having a magnetic means for moving the electrode or shield.
(1) Note. The magnetic means may be an electromagnet connected in circuit with an electrode. A mere conductive connection is not sufficient circuit to exclude the organization from Class 313.

314, Electric Lamp and Discharge Devices: Consumable Electrodes, for consumable electrode type arc lamps and other consumable electrode type discharge devices having magnetic means for feeding one of the electrodes towards the other electrode as it or they are consumed in the discharge or for separating the electrodes from each other to start the space discharge. See especially
66+, 69+, 78, 105+, and 113+; not that subclasses 69+, provides for rotary electric motors while the other subclasses mentioned provide for electromagnets. 315, Electric Lamp and Discharge Devices: Systems,
39.59, for discharge devices having an electrode formed so as to provide a structure having distributed inductance and capacitance and operable in a magnetic field (e.g., magnetrons), the device being provided with magnetically
actuated means for varying the impedance of the distributed impedance structure, subclasses 331+ for systems for supplying electrical energy to discharge devices of the gas or vapor type including those which are provided with a liquid electrode where the discharge device is provided with an auxiliary starting electrode which is moved into contact with and then separated from one of the principal electrodes by magnetic means to start the discharge device.
