Abstract
Abstract In the ozone generator, the inner electrodes which have been continuous until now, are subdivided into individual electrically series-connected segments (7) which are mechanically decoupled from one another. In this manner, ozoniers of almost arbitrary length can be implemented with gap widths of around 0.5 mm.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
95 words
Ozone generator with a tubular outer electrode and a plurality of inner electrodes which exhibit a dielectric layer on their surface facing the outer electrode, with means for spacing the inner electrodes from the outer electrode and forming of an annular discharge gap and means for electrically connecting all electrodes to an alternating current source, wherein the inner electrodes comprise a plurality of cascaded mechanically decoupled electrode segments which are electrically connected to one another in groups, and each segment is supported spaced from the outer electrode independently of the segment immediately adjacent to it.
Claim 2
Dependent Claim
95 words
Ozone generator with a tubular outer electrode and a plurality of inner electrodes which exhibit a dielectric layer on their surface facing the outer electrode, with means for spacing the inner electrodes from the outer electrode and forming of an annular discharge gap and means for electrically connecting all electrodes to an alternating current source, wherein the inner electrodes comprise a plurality of cascaded mechanically decoupled electrode segments which are electrically connected to one another in groups, and each segment is supported spaced from the outer electrode independently of the segment immediately adjacent to it.
Claim 3
Dependent Claim
44 words
Ozone generator as claimed in claim 1, wherein, in a duplex arrangement, one group is connected to a first busbar and the other group is connected to the other busbar, and that in a simplex arrangement, all segments are connected to a single busbar.
Claim 4
Dependent Claim
37 words
Ozone generator as claimed in claims 1 or 2, wherein the inner electrode is a metal tube which is closed at one end and the outer wall of which is coated with a ceramic or plastic/ceramic dielectric.
Claim 5
Dependent Claim
32 words
Ozone generator as claimed in claim 3, wherein, for electrically connecting two adjacent metal tubes, one is provided with a contact element which plunges into the interior of the adjacent metal tube.
Claim 6
Dependent Claim
27 words
Ozone generator as claimed in claims 1 or 2, wherein the inner electrode is constructed as metallic coating of a glass tube or of a plastic tube.
Claim 7
Dependent Claim
38 words
Ozone generator as claimed in claim 5, wherein the tube is closed at one end and is provided at the closed end with a contact element which plunges into the interior of the glass tube adjacent to it.
Claim 8
Dependent Claim
38 words
Ozone generator as claimed in claim 5, wherein the tube is open at both ends and is provided at one end with a plug, which plug exhibits means for electrically connecting the contact elements of adjacent glass tubes.
