  • Patent number: 7029637
    Abstract: An ozone generation cell has a first conductor generally having a line geometry and a second conductor having a first groove formed in a surface thereof, and having first and second flanks on opposite sides of the first groove. The second conductor and the first groove are arranged such that the first groove follows the first conductor in parallel spaced-apart relation. The ozone generation cell also has a first dielectric having a first passage-defining portion positioned between the first conductor and the first groove. The first dielectric has first and second side portions on opposite sides of the passage-defining portion that are generally parallel to the first and second flanks respectively. The first passage-defining portion is spaced-apart from only one of the first conductor and the first groove to form a first fluid passageway defined in part by the first passage-defining portion.

  • Publication number: 20040136885
    Abstract: An ozone generation apparatus and method is described. The apparatus includes a dielectric body having a wall defining a fluid passageway operable to contain and conduct fluid containing oxygen, a first conductor generally having a line geometry extending lengthwise in the passageway and a second conductor generally having a line geometry, supported outside of the passageway by the body to extend generally parallel to the first conductor. The first and second conductors are arranged to cause an electric field to be established therebetween and through the fluid passageway when an electric potential is applied across the first and second conductors.
