Abstract
Abstract An ion generator having an electrical cable for producing a corona field for capacitors having emitter electrodes discharging ions toward a grounded shield that protects the electrodes from accidental touching and discharge and causes the ions to assume an enlarging path of ion discharge.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
121 words
In an ion generator, a plurality of longitudinally arranged, relatively spaced ion emitter electrodes each having an emitter point, a grounded metallic shield having an uninterrupted longitudinal opEning defined by walls relatively spaced laterally on opposite sides of each of said plurality of longitudinally arranged electrodes and extending radially beyond the emitter points of said electrodes whereby ions emitted at said emitter points move radially outward through said opening and laterally toward the opposite walls of said grounded shield to assume a mushroom shape with said emitter points protected within the confines of said shield, an electric cable, a capacitor about said cable and in electrical contact with each of said emitter electrodes, and insulator means between said shield and capacitor.
Claim 2
Dependent Claim
121 words
In an ion generator, a plurality of longitudinally arranged, relatively spaced ion emitter electrodes each having an emitter point, a grounded metallic shield having an uninterrupted longitudinal opEning defined by walls relatively spaced laterally on opposite sides of each of said plurality of longitudinally arranged electrodes and extending radially beyond the emitter points of said electrodes whereby ions emitted at said emitter points move radially outward through said opening and laterally toward the opposite walls of said grounded shield to assume a mushroom shape with said emitter points protected within the confines of said shield, an electric cable, a capacitor about said cable and in electrical contact with each of said emitter electrodes, and insulator means between said shield and capacitor.
Claim 3
Dependent Claim
38 words
In a generator as in claim 1 wherein there are a plurality of capacitors each in electrical contact with every two of said plurality of relatively spaced emitter electrodes, and said electrodes are longitudinally aligned with each other.
Claim 4
Dependent Claim
59 words
In an ion generator as in claim 2 wherein said plurality of capacitors are circular metallic bands on an insulated sleeve, said emitter electrodes extending radially outward from their electrical contact with their respective bands, and said shield is in radially spaced relation to and outward of said capacitors and the emitter points of each of said emitter electrodes.
Claim 5
Dependent Claim
78 words
In an ion generator as in claim 3, said cable, capacitor sleeve, insulator means and shield being concentrically arranged serially, a plug at each end of said generator supporting said serial arrangement, one of said plugs having an opening therethrough for the passage of an end of said cable into the generator through one end thereof, and a closed plug at the other end of said generator receiving and closing the end of the cable in the generator.
Claim 6
Dependent Claim
28 words
In an ion generator as in claim 4, an end clamp at each end of said generator clamping said shield to said end plugs and grounding said shield.
Claim 7
Dependent Claim
100 words
An ion generator comprising an electrical cable, an insulator sleeve about said cable and having a plurality of relative axially spaced capacitors thereon, at least two ion emitter electrodes in electrical contact with each of said capacitors, each such electrode having an emitter end directed radially outward from its respective capacitor, a grounded shield having relatively spaced walls spaced outward of said capacitors and said electrode emitter ends, said walls being spaced on opposite sides of said electrodes, and insulator means between said capacitors and shield with said electrodes extending therethrough toward but short of the space between said walls.
Claim 8
Dependent Claim
100 words
An ion generator comprising an electrical cable, an insulator sleeve about said cable and having a plurality of relative axially spaced capacitors thereon, at least two ion emitter electrodes in electrical contact with each of said capacitors, each such electrode having an emitter end directed radially outward from its respective capacitor, a grounded shield having relatively spaced walls spaced outward of said capacitors and said electrode emitter ends, said walls being spaced on opposite sides of said electrodes, and insulator means between said capacitors and shield with said electrodes extending therethrough toward but short of the space between said walls.
Claim 9
Dependent Claim
58 words
An ion generator as in claim 6, a plug at each end of said shield supporting said cable, sleeve, insulator means and shield serial in co-axial arrangement and closing the opposite ends of said ion generator, and clamp means engaging each of said end plugs and said shield to retain said serial arrangement and to ground said shield.
