Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
108 words
7. A process for the mass production of ozone, comprising warming a liquid oxygen to a temperature not higher than the boiling point of ozone by means of a heat exchanger, thereby obtaining a gasified oxygen; introducing said gasified oxygen to a reaction chamber; impinging ozoning radiations selected from the group consisting of laser beams, and plasma discharges upon said gasified oxygen, hereby generating ozone; and collecting said ozone in its liquid state separated from said gaseous oxygen under said thermal atmosphere having a temperature not higher than the boiling point of ozone and wherein unreacted oxygen is recycled to the heat exchanger for reuse in the process.
Claim 2
Dependent Claim
108 words

Claim 3
Dependent Claim
14 words
A process as claimed in claim 1, wherein the ozoning radiations are laser beams.
Claim 4
Dependent Claim
14 words
A process as claimed in claim 1, wherein the ozonizing radiations are plasma discharges.
Claim 5
Dependent Claim
111 words
A process for the mass production of ozone from oxygen comprising: (a) converting liquid oxygen to its gaseous state by warming it to a temperature above its boiling point and below the boiling point of ozone; (b) maintaining the gaseous oxygen at a temperature between the boiling point of oxygen and the boiling point of ozone and, while it is so maintained, impinging it with ozonizing radiations selected from the group consisting of laser beams and plasma discharges whereby liquid ozone is directly formed; and (c) separating the formed liquid ozone from the gaseous oxygen; (d) and wherein unreacted oxygen is recycled to the heat exchanger for reuse in the process.
Claim 6
Dependent Claim
111 words
A process for the mass production of ozone from oxygen comprising: (a) converting liquid oxygen to its gaseous state by warming it to a temperature above its boiling point and below the boiling point of ozone; (b) maintaining the gaseous oxygen at a temperature between the boiling point of oxygen and the boiling point of ozone and, while it is so maintained, impinging it with ozonizing radiations selected from the group consisting of laser beams and plasma discharges whereby liquid ozone is directly formed; and (c) separating the formed liquid ozone from the gaseous oxygen; (d) and wherein unreacted oxygen is recycled to the heat exchanger for reuse in the process.
Claim 7
Dependent Claim
14 words
A process as claimed in claim 4, wherein the ozonizing radiations are laser beams.
Claim 8
Dependent Claim
14 words
A process as claimed in claim 4, wherein the ozonizing radiations are plasma discharges.
Claim 9
Dependent Claim
16 words
The process of claim 4, wherein the temperature is maintained between -183° C. and -112° C.
Claim 10
Dependent Claim
16 words
The process of claim 4, wherein the temperature is maintained between -150° C. and -120° C.
