Abstract
Abstract An ozone generator comprises a plurality of inner tubular electrodes each of which has a multiplicity of outwardly extending dimpled projections and each of which is configured for a sliding fit within a dielectric carrier sleeve. An outer tubular electrode is mounted coaxially over each carrier sleeve by means of non-conductive spacers and forms an annular air passageway between each outer electrode and sleeve. The assemblies are mounted longitudinally in an enclosed cylindrical housing by means of an air barrier which surrounds the outer electrodes and divides the housing into upper and lower compartments so that pressurized air which is introduced through an air inlet into the lower compartment passes upwardly through the passageways to the upper compartment where it exits the housing through an ozone outlet. Electrical conductors connect the pairs of inner and outer electrodes in parallel across a source of high voltage remote from the housing.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
231 words
An ozone generator comprising: (a) an elongated hollow housing closed at both ends, (b) an air inlet adjacent one end of the housing, (c) an ozone outlet adjacent the opposite end of the housing, (d) a plurality of elongated electrode assemblies in the housing extending longitudinally therein and spaced apart from each other, and (e) an electrically non-conductive air barrier wall disposed transversely within the housing intermediate the ends of the housing and electrode assemblies, forming a seal about the inner wall of the housing and the outer surfaces of the outer electrodes of the electrode assemblies for preventing the passage of air between the spaced electrode assemblies from the air inlet to the ozone outlet, (f) each electrode assembly comprising: (1) elongated inner and outer electrodes of tubular form disposed concentrically with respect to each other and arranged for connection across a source of high voltage, (2) an elongated insulator member of dielectric material of tubular form disposed concentrically between the inner and outer electrodes and forming with one of said electrodes an elongated passageway therebetween communicating at one end with the air inlet end of the housing and at the opposite end with the ozone outlet end of the housing, and (3) a multiplicity of spaced protrusions on the surface of one of the electrodes facing the other electrodes, forming a multiplicity of electrical discharge points between said electrodes.

An ozone generator comprising: (a) an elongated hollow housing closed at both ends, (b) an air inlet adjacent one end of the housing, (c) an ozone outlet adjacent the opposite end of the housing, (d) a plurality of elongated electrode assemblies in the housing extending longitudinally therein and spaced apart from each other, and (e) an electrically non-conductive air barrier wall disposed transversely within the housing intermediate the ends of the housing and electrode assemblies, forming a seal about the inner wall of the housing and the outer surfaces of the outer electrodes of the electrode assemblies for preventing the passage of air between the spaced electrode assemblies from the air inlet to the ozone outlet, (f) each electrode assembly comprising: (1) elongated inner and outer electrodes of tubular form disposed concentrically with respect to each other and arranged for connection across a source of high voltage, (2) an elongated insulator member of dielectric material of tubular form disposed concentrically between the inner and outer electrodes and forming with one of said electrodes an elongated passageway therebetween communicating at one end with the air inlet end of the housing and at the opposite end with the ozone outlet end of the housing, and (3) a multiplicity of spaced protrusions on the surface of one of the electrodes facing the other electrodes, forming a multiplicity of electrical discharge points between said electrodes.
Claim 3
Dependent Claim
72 words
The ozone generator of claim 1 wherein the inner surface of the outer electrode and the outer surface of the tubular insulator are smooth, the multiplicity of protrusions project outwardly from the inner tubular electrode of each assembly, the opposite ends of the tubular insulator member are sealed against the entrance of contaminants, and the air passageway is formed between the confronting smooth surfaces of the tubular insulator member and outer electrode.
