Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
84 words
An ozone generator comprising a plurality of spaced-apart metallic electrodes and at least one thin dielectric layer between the electrodes thereby defining a corona chamber; electrical means for imposing a silent discharge potential in the corona chamber; supply means for passing an oxygen-containing gas through the corona chamber; a bed of silica gel adsorbent and means for maintaining said bed of silica gel adsorbent particles in the corona chamber for adsorbing ozone generated therein; and means for desorbing the ozone from the silica gel.
Claim 2
Dependent Claim
84 words
An ozone generator comprising a plurality of spaced-apart metallic electrodes and at least one thin dielectric layer between the electrodes thereby defining a corona chamber; electrical means for imposing a silent discharge potential in the corona chamber; supply means for passing an oxygen-containing gas through the corona chamber; a bed of silica gel adsorbent and means for maintaining said bed of silica gel adsorbent particles in the corona chamber for adsorbing ozone generated therein; and means for desorbing the ozone from the silica gel.
Claim 3
Dependent Claim
29 words
An ozone generator according to claim 1 further comprising means for confining the gas stream in the corona chamber and ports for inlet and outlet of the gas stream.
Claim 4
Dependent Claim
37 words
In an ozone generator according to claim 1, said supply means further comprising means for adding silica gel particles to the gas and means for fluidizing the silica gel particles with the gas in the corona chamber.
Claim 5
Dependent Claim
29 words
In an ozone generator according to claim 3, means for separating ozone-laden silica gel particles from the gas and means for regenerating the silica gel to recover adsorbed ozone.
Claim 6
Dependent Claim
23 words
An ozone generator according to claim 1, further comprising means for containing the silica gel as a static bed in the corona chamber.
Claim 7
Dependent Claim
35 words
In an ozone generator having at least one dielectric layer between spaced-apart electrodes and having a corona chamber, the improvement which comprises: dielectric solid adsorbent particles disposed in the corona chamber for selectively adsorbing ozone.
Claim 8
Dependent Claim
35 words
In an ozone generator having at least one dielectric layer between spaced-apart electrodes and having a corona chamber, the improvement which comprises: dielectric solid adsorbent particles disposed in the corona chamber for selectively adsorbing ozone.
