DEFINITION

Classification: 315/58

(under subclass 56) Discharge devices, having structurally combined therewith an electric circuit impedance.

SEE OR SEARCH THIS CLASS, SUBCLASS:

33, where the discharge device is combined with other circuit elements so as to constitute a portable, self-contained apparatus.

35, and indented subclasses, for plural discharge devices combined with a circuit impedance.

39.51, and 40, for discharge devices which have an electrode formed to provide inductance, see subclass 39.51 where the electrode has distributed inductance and capacitance (e.g., a resonator) and which are provided with an electromagnet for subjecting the discharge space to the magnetic field, and subclass 40 for discharge devices for having an electrode formed as an inductor or as a structure having inductance and capacitance (e.g., resonator).

41, for discharge devices combined with an inductance which is connected between two of the electrodes of the discharge device.

46, and indented subclasses for discharge devices combined with a filament, electric heater or resistance in shunt with the discharge electrodes. 50, for discharge devices combined with temperature modifying means, the temperature modifying means being either designed to function as a circuit impedance, or combined with a circuit impedance.

56, for discharge devices combined with an electric heater or filament in series with the discharge electrodes.
