DEFINITION

Classification: 315/62

(under subclass 58) Discharge devices, wherein the impedance element is an inductive impedance.

SEE OR SEARCH THIS CLASS, SUBCLASS:

39+, for discharge devices which have structurally combined therewith a transmission line of the distributed parameter type, (e.g., waveguide, coaxial cable, etc.).

39.51+, for discharge devices having an electrode formed as to provide distributed inductance and capacitance (e.g., resonator and which are provided with an electromagnet for influencing the space discharge (e.g., magnetrons).

40, for discharge devices having an electrode formed as an inductive impedance.

41, and indented subclasses, for discharge devices combined with an inductive impedance which is connected between two electrodes of the discharge device.

54, for discharge devices combined with a plurality of inductive impedances. 223, where the discharge device is connected to the secondary circuit of a current supply transformer, the primary circuit of the transformer including an inductance and a periodic switch.

242, and 244, where the supply circuit of the discharge device includes an inductance and a condenser.

263, for discharge device systems wherein the discharge device is provided with an auxiliary starting electrode and an inductance is included in the auxiliary electrode circuit and the discharge device is supplied with alternating current.

283, and indented subclasses, and the subclasses specified in the notes to the definition of these subclasses, for discharge device systems which are connected to a source of alternating current supply and which are provided with an inductance in the supply circuit.

289, and indented subclass, for miscellaneous systems under the class definition provided with an inductance in the supply circuit.
