Abstract
Abstract The ozone generator having in combination a first tubular electrode surrounded by a tubular dielectric which, in turn, is surrounded by a second tubular electrode. Entry of air to be ozonized occurs into a first end of the first tubular electrode and, through a pattern of perforations, is permitted to escape therefrom into an annular volume between the first tubular electrode and the tubular dielectric. The first tubular electrode is centrally, radially, sealed so as to form two chemically and electrically separate chambers. The second or output chamber of the first tubular electrode is provided with a pattern of perforations which permits re-entry of the air, which has been ozonized while exposed to a voltage across the annular volume between the outside of the first electrode and the dielectric, to the second or output part of the first tubular electric.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
334 words
An ozone generator, comprising: (a) an elongate cylindrical first electrode having a first end, a middle, and a second end, the first end comprising a narrow opening into which air to be ozonized is pumped, said middle comprising a radial seal separating said first electrode into a first and second chamber, said second end comprising a narrow opening out of which ozonized air is drawn, said first chamber having fluid communication with said first end, and said second chamber having fluid, communication with said second end, said first chamber having a plurality of perforations in the wall of said first electrode, said perforations disposed near said first end thereof, said second chamber having a plurality of perforations in the wall of said first electrode disposed near said second end of said first electrode; (b) a cylindrical dielectric proportioned to extend along the length of said first electrode and at least sufficiently to cover said first and second pluralities of perforations, the geometry of said dielectric thereby defining an annulus between the outside of said first electrode and the inside of said cylindrical dielectric; (c) annular sealing means for forming a fluid-tight seal at both ends of said annulus; (d) a elongate cylindrical second electrode adhered to and disposed about substantially the entire lateral surface of said dielectric; and (e) power means electrically connected to said first and second electrodes for the selective application of electrical potential therebetween, whereby air pumped into the first end of said first electrode is partially pressurized within said first chamber, forced-out through said first plurality of perforations into said annulus, then exposed to a high voltage while moving through said annulus toward said second end of said first electrode, forced into the second chamber of said first electrode through said second plurality of perforations, then partially pressurized therein, and drawn out of the second end of said first electrode, the air thereby having been at least partially ionized by virtue of the corona-effect electric discharge occuring within said annulus.
Claim 2
Dependent Claim
334 words
An ozone generator, comprising: (a) an elongate cylindrical first electrode having a first end, a middle, and a second end, the first end comprising a narrow opening into which air to be ozonized is pumped, said middle comprising a radial seal separating said first electrode into a first and second chamber, said second end comprising a narrow opening out of which ozonized air is drawn, said first chamber having fluid communication with said first end, and said second chamber having fluid, communication with said second end, said first chamber having a plurality of perforations in the wall of said first electrode, said perforations disposed near said first end thereof, said second chamber having a plurality of perforations in the wall of said first electrode disposed near said second end of said first electrode; (b) a cylindrical dielectric proportioned to extend along the length of said first electrode and at least sufficiently to cover said first and second pluralities of perforations, the geometry of said dielectric thereby defining an annulus between the outside of said first electrode and the inside of said cylindrical dielectric; (c) annular sealing means for forming a fluid-tight seal at both ends of said annulus; (d) a elongate cylindrical second electrode adhered to and disposed about substantially the entire lateral surface of said dielectric; and (e) power means electrically connected to said first and second electrodes for the selective application of electrical potential therebetween, whereby air pumped into the first end of said first electrode is partially pressurized within said first chamber, forced-out through said first plurality of perforations into said annulus, then exposed to a high voltage while moving through said annulus toward said second end of said first electrode, forced into the second chamber of said first electrode through said second plurality of perforations, then partially pressurized therein, and drawn out of the second end of said first electrode, the air thereby having been at least partially ionized by virtue of the corona-effect electric discharge occuring within said annulus.
