Abstract
Abstract This invention relates to an ozone generator basically comprised of at least two electrodes having a dielectric therebetween. The electrodes are made from stainless steel wire mesh and the dielectric is a sheet of high quality material such as mica. The ozone generator utilizes a relatively low amperage current in conjunction with a compact and simplified mounting and electrical connection of the generator to effectively provide substantial amounts of ozone for purifying purposes.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
23 words
An ozone generator as in claim 1 wherein said electrode means each include a pair of substantially rectangular flattened stainless steel wire grids.
Claim 2
Dependent Claim
46 words
An ozone generator as in claim 1 wherein each of said support means includes an inwardly and downwardly extending section that is adapted to mount said eyebolts which extend into the center of the ozonizer means to position said wire grids on a common longitudinal axis.
Claim 3
Dependent Claim
49 words
An ozone generator according to claim 1 where the grids have a carbon content of less than 0.08 percent, where several units of electrode means with dielectric sheets between all electrodes of different charge are provided, and where there is about 1/4 -inch space between adjacent sheets of dielectric.
Claim 4
Dependent Claim
71 words
An ozone generator according to claim 1 where the generator is adapted to operate at between 2,000 and 4,000 volts, and the grids are made from stainless steel having a chromium content of 18 percent to 20 percent, a nickel content of 8 percent to 12 percent, and the carbon is less than 0.08 percent, and where there is an 0.0633-inch opening between wires and an open area of 57.2 percent.
Claim 5
Dependent Claim
32 words
An ozone generator as in claim 1 wherein said dielectric is formed from a thin piece of a substantially rectangular sheet of mica that protrudes from all margins of said wire grids.
Claim 6
Dependent Claim
56 words
An ozone generator according to claim 6 where the mica is muscovite having a specific gravity between 2.6 to 3.2, specific heat of 0.207, Moh hardness of 2.8 to 3.2, Shore hardness of 80 to 150, volume resistivity in ohms/cm of 2 X 1013 to 1 X 1017 and a dielectric constant of 6.5 to 8.7.
Claim 7
Dependent Claim
31 words
An ozone generator as in claim 1 wherein each of said support means is comprised of an L-shaped angle forming seats which receive and support the dielectric of the ozonizer means.
Claim 8
Dependent Claim
57 words
An ozone generator as in claim 8 wherein the L-shaped angles have vertically extending legs inclined slightly outwardly out of vertical whereby the dielectric sheets can be slid into the seats formed by the flanges and be firmly held in position because of the close relationship between the grids secured to adjacent ones of said electrode means.
