Abstract
Abstract Conducting plates of opposite electrical potential are alternately disposed and spaced apart and immersed in a dielectric fluid in a chamber. Gas is supplied to the bottom of the chamber and passes through the fluid and over the plates. A partial vacuum is maintained in the region above the surface of the dielectric, from which the gas is extracted.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
82 words
A gas ionizing apparatus comprising, a chamber adapted to hold dielectric fluid, overlapping, spaced apart plates of conductive material disposed within said chamber so that upon the addition of dielectric fluid to said chamber said plates would be immersed in said fluid, alternate said plates being connectable to sources of different electrical potential, means for supplying a gas to said chamber and means for extracting a gas from said chamber, said means being disposed so that said gas passes over said plates.
Claim 2
Dependent Claim
82 words
A gas ionizing apparatus comprising, a chamber adapted to hold dielectric fluid, overlapping, spaced apart plates of conductive material disposed within said chamber so that upon the addition of dielectric fluid to said chamber said plates would be immersed in said fluid, alternate said plates being connectable to sources of different electrical potential, means for supplying a gas to said chamber and means for extracting a gas from said chamber, said means being disposed so that said gas passes over said plates.
Claim 3
Dependent Claim
33 words
The apparatus of claim 1 in which said means for extracting a gas from said chamber includes means for creating a partial vacuum in the region of said chamber not containing said fluid.
Claim 4
Dependent Claim
31 words
The apparatus of claim 1 in which said means for supplying a gas to said chamber includes means for supplying said gas to the region of said chamber containing said fluid.
Claim 5
Dependent Claim
40 words
The apparatus of claim 2 in which said means for supplying a gas to said chamber includes means for supplying said gas to a region of said chamber containing said fluid and remote from said region not containing said fluid.
Claim 6
Dependent Claim
47 words
The apparatus of claim 1 in which a first set of said plates are connected to a first terminal and a second set of said plates are connected to a second terminal, the plates of said first and second sets alternating in their disposition in said chamber.
Claim 7
Dependent Claim
21 words
The apparatus of claim 5 in which respective pairs of said plates define gas passages therebetween in a high electric field.
Claim 8
Dependent Claim
25 words
The apparatus of claim 6 in which said plates are disposed at an angle to an axis passing substantially through the centers of said plates.
Claim 9
Dependent Claim

The apparatus of claim 7 in which said angle is substantially 45°.
Claim 10
Dependent Claim
169 words
A gas ionizing apparatus comprising, a chamber adapted to hold dielectric fluid, overlapping, equally spaced apart plates of conductive material disposed within said chamber so that upon the addition of said fluid to said chamber said plates would be immersed in said fluid, a first set of said plates being connected to a first terminal and a second set of said plates being connected to a second terminal, the plates of said first and second sets alternating in their disposition in said chamber, means for extracting gas from said chamber including means for creating a partial vacuum in the region of said chamber not containing said fluid when said plates are immersed in said fluid, means for supplying gas to said chamber, including means for supplying said gas to the region of said chamber containing said fluid when said plates are immersed in said fluid, said means for extracting gas and said means for supplying gas to said chamber being disposed so that said gas passes over said plates.
Claim 11
Dependent Claim
169 words
A gas ionizing apparatus comprising, a chamber adapted to hold dielectric fluid, overlapping, equally spaced apart plates of conductive material disposed within said chamber so that upon the addition of said fluid to said chamber said plates would be immersed in said fluid, a first set of said plates being connected to a first terminal and a second set of said plates being connected to a second terminal, the plates of said first and second sets alternating in their disposition in said chamber, means for extracting gas from said chamber including means for creating a partial vacuum in the region of said chamber not containing said fluid when said plates are immersed in said fluid, means for supplying gas to said chamber, including means for supplying said gas to the region of said chamber containing said fluid when said plates are immersed in said fluid, said means for extracting gas and said means for supplying gas to said chamber being disposed so that said gas passes over said plates.
Claim 12
Independent Claim
62 words
A method for ionizing gas comprising, partially filling a chamber with dielectric fluid, immersing in said fluid overlapping, spaced apart plates of conductive material, connecting alternate sets of said plates to different electric potentials, supplying gas to a region of the fluid remote from its surface, and creating a partial vacuum in the region of the chamber not filled with said fluid.
Claim 13
Independent Claim
62 words
A method for ionizing gas comprising, partially filling a chamber with dielectric fluid, immersing in said fluid overlapping, spaced apart plates of conductive material, connecting alternate sets of said plates to different electric potentials, supplying gas to a region of the fluid remote from its surface, and creating a partial vacuum in the region of the chamber not filled with said fluid.
