34, for discharge devices which have an antenna structurally combined therewith so as to form a unitary device.

39, for discharge devices which have a waveguide, coaxial cable or resonant parallel wire transmission line structurally combined therewith so as to form a unitary device.

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

46, for devices which include a discharge device and a filament lamp which are structurally combined in a single unitary device, the filament being connected in shunt with the discharge electrodes.

49, for devices which include a discharge device and a filament lamp which are structurally combined in a single unitary device, the filament being connected in series relation with respect to the discharge electrodes.

50, for discharge devices which are provided with temperature modifying means, the temperature modifying means being formed so as to act as a circuit impedance or combined with a circuit impedance, the discharge device, temperature modifying means, and the impedance all being structurally combined in a single unitary device.
