Abstract
Abstract An electrode for use as one of a pair of spaced apart electrodes in a corona reactor cell having a corona discharge chamber between the interior surfaces of the electrodes, said one electrode being a flat, rectangular, planar plate having a continuous peripheral edge that curves away from the plane of the plate in a direction away from the interior surface thereof, said edge including the entire peripheral edge of said one electrode and having a uniform width and height, and said one electrode having a ceramic dielectric coating covering the entire area of said interior surface thereof. The electrode can include one or a pair of passageways extending transversely completely therethrough in which case the electrode includes a peripheral wall of the side thereof opposite the interior surface and surrounding and defining the passageway, and in which case the ceramic dielectric coating also covers the interior surface of the peripheral wall.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
140 words
An electrode for use as one of a pair of electrodes in a corona reactor cell of a corona reactor adapted to expose a fluid to a corona discharge produced in a corona discharge chamber between the interior surface of each of a pair of corona reactor electrodes, said electrode comprising a flat, rectangular, planar, metal plate having a continuous peripheral edge that curves away from the plane of the plate in a direction away from the interior surface thereof, said curving edge including the entire peripheral edge of said plate, said curving edge having a uniform width and height, and said electrode having a ceramic dielectric coating covering the entire area of said interior surface of said plate, and said plate being imperforate except for only a pair of spaced-apart passageways extending transversely completely through said plate and coating.
Claim 2
Dependent Claim
140 words
An electrode for use as one of a pair of electrodes in a corona reactor cell of a corona reactor adapted to expose a fluid to a corona discharge produced in a corona discharge chamber between the interior surface of each of a pair of corona reactor electrodes, said electrode comprising a flat, rectangular, planar, metal plate having a continuous peripheral edge that curves away from the plane of the plate in a direction away from the interior surface thereof, said curving edge including the entire peripheral edge of said plate, said curving edge having a uniform width and height, and said electrode having a ceramic dielectric coating covering the entire area of said interior surface of said plate, and said plate being imperforate except for only a pair of spaced-apart passageways extending transversely completely through said plate and coating.
