Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
95 words
In a device for producing ozone from oxygen or oxygen containing gas by means of static electrical discharge in a space through which the gas flows, which space is essentially formed by a tubular outer electrode and a voltage carrying inner electrode surrounded by the outer electrode whereby a dielectric which separates the electrodes is installed in this space, the improvement being in that said inner electrode consists of a plurality of metal wires, and that ratio of the diameter of said outer electrode to the diameter of said inner electrode being greater than 2.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
18 words
Device according to claim 1, characterized therein that said plurality of metal wires consist of several stranded rod.
Claim 4
Dependent Claim
26 words
Device according to claim 1, characterized by a precise concentric configuration of said inner electrode and said dielectric and said outer electrode by means of spacers.
Claim 5
Dependent Claim
27 words
Device according to claim 3, characterized therein that said spacers are in the form of at least one spiral glued-on plastic band installed on said inner electrode.
Claim 6
Dependent Claim
24 words
Device according to claim 1, characterized therein that the common axis of said inner electrode and said dielectric and said outer electrode is curved.
Claim 7
Dependent Claim
45 words
Device according to claim 1, characterized therein that said inner electrode and said dielectric and said outer electrode are connected in parallel with a common head piece for the oxygen or oxygen rich gas and a common bottom piece for the generated ozone containing gas.
Claim 8
Dependent Claim
22 words
Device according to claim 1, characterized therein that said inner electrode consists of wire with a diameter of 0.5 to 3 mm.
Claim 9
Dependent Claim
14 words
Device according to claim 3, characterized therein that said dielectric is made of glass.
Claim 10
Dependent Claim
14 words
Device according to claim 3, characterized therein that said dielectric is made of plastic.
