Abstract
Abstract In ozone generators having segmented inner electrodes (7), the electric connection of the segments is effected by means of plane contact areas (10) applied to the ends of the segments. A tension rod (11) passing through all segments ensures cohesion and, at the same time, is used as the connecting element for supplying the ozone generator with power.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
117 words
A device for generating ozone from oxygen or an oxygen containing gas, comprising: a plurality of tubular inner electrodes having adjoining ends arranged end-to-end; an electrical contact area formed at each adjoining end of said plurality of inner electrodes; a dielectric layer coating an outer periphery of each of said plurality of inner electrodes; a tubular outer electrode concentrically surrounding said plurality of inner electrodes; means for spacing said outer electrode from said inner electrodes to form a discharge gap between said outer electrode and said dielectric layer; and a clamping means for axially compressing said plurality of inner electrodes toward one another to provide electrical and mechanical connection of said inner electrodes at said adjoining ends.
Claim 2
Independent Claim
117 words
A device for generating ozone from oxygen or an oxygen containing gas, comprising: a plurality of tubular inner electrodes having adjoining ends arranged end-to-end; an electrical contact area formed at each adjoining end of said plurality of inner electrodes; a dielectric layer coating an outer periphery of each of said plurality of inner electrodes; a tubular outer electrode concentrically surrounding said plurality of inner electrodes; means for spacing said outer electrode from said inner electrodes to form a discharge gap between said outer electrode and said dielectric layer; and a clamping means for axially compressing said plurality of inner electrodes toward one another to provide electrical and mechanical connection of said inner electrodes at said adjoining ends.
Claim 3
Dependent Claim
28 words
A device as claimed in claim 1, wherein the electrical contact area comprises a planar surface extending orthogonally with respect to a longitudinal axis of the inner electrodes.
Claim 4
Dependent Claim
21 words
A device as claimed in claim 1 or 2, wherein adjacent inner electrodes directly contact one another at said adjoining ends.
Claim 5
Dependent Claim
24 words
A device as claimed in claim 1 or 2, wherein a contact disk of ductile material is provided between two of said adjoining ends.
Claim 6
Dependent Claim
31 words
A device as claimed in claim 1 or 2, further comprising a contact disk attached to each of said adjoining ends, said electrical contact area being formed on said contact disk.
Claim 7
Dependent Claim
40 words
A device as claimed in claim 1, further comprising a contact body interposed between two of said adjoining ends, said contact body having an external surface contour complementary to a contour of said adjoining ends of said adjacent inner electrodes.
Claim 8
Dependent Claim
26 words
A device as claimed in claim 1 or 6, wherein a recess is formed in the adjoining end of at least one of said tubular electrodes.
Claim 9
Dependent Claim
24 words
A device as claimed in claim 7, wherein said contact body serves as said means for spacing said outer electrode from said inner electrodes.
Claim 10
Dependent Claim
15 words
A device as claimed in claim 8, wherein said contact body has a hemispherical shape.
Claim 11
Independent Claim
27 words
A device as claimed in any of claims 1, 2 or 6, wherein said clamping means comprises a tension rod passing through each of said inner electrodes.
Claim 12
Dependent Claim
29 words
A device as claimed in claim 10, wherein said clamping means further comprises a spring urging said inner tubular electrodes into contact with one another along said tension rod.
