Abstract
Abstract An energizing coil encircles a tubular light-resonating cavity containing a gas mixture, the pressure of the gas mixture and the ratio of the cavity inside diameter to the coil diameter having predetermined values. A high frequency voltage is applied to the coil, the magnitude of the voltage being such as to produce and maintain an abnormal glow of the gas mixture substantially over the axial length of the coil.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
22 words
The invention as recited in claim 1, wherein the frequency of the voltage is equal to the resonance frequency of the coil.
Claim 2
Dependent Claim
39 words
The invention as recited in claim 1, wherein the coil is made of a conductor having a hemispherical cross section with the flat surface thereof presented to the cavity, and wherein such flat surface has a good light-reflecting characteristic.
Claim 3
Dependent Claim
45 words
The invention as recited in claim 1, wherein the said light resonating cavity is sealed, and including an auxiliary cavity of fixed volume and communicating with the light-resonating cavity, the volume of said auxiliary cavity being at least equal to that of the light-resonating cavity.
Claim 4
Dependent Claim
73 words
The invention as recited in claim 1, including a vessel containing a supply of the gas mixture, means connected between the said vessel and one end of the light-resonating cavity for admitting the gas mixture into the said cavity, means for controlling the rate at which the gas mixture is admitted into the cavity, and means for removing the gas mixture from the other end of said cavity at a predetermined constant rate.
