Abstract
Abstract My invention relates to the use of laser light energy to excite oxygen from its normal ambient state to that required for it to convert to molecular ozone. Laser light energy is passed through a flowing stream of oxygen molecules and atoms, either when the oxygen is in a gaseous form or as when it is absorbed as a gas in a halogenated hydrocarbon inert liquid; thus producing ozone, when in the gaseous form, for immediate use, or when absorbed in the inert liquid, for later use.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
116 words
A method for generating ozone by conversion of oxygen with laser light energy excitation of the oxygen to ozone comprising the steps of: selecting an inert dielectric liquid not chemically reactive with ozone; injecting said liquid under superatmospheric pressure through a venturi type injector, thereby causing oxygen to be received through an entry nozzle directly into the venturi throat area and mixing with the inert liquid where it is absorbed; projecting a beam of laser light energy into the venturi throat area into the liquid pregnant with absorbed oxygen, thus converting a part of the absorbed oxygen to absorbed zone, and causing the laser light energy to be reflected back into the liquid for greater efficiency.
Claim 2
Independent Claim
116 words
A method for generating ozone by conversion of oxygen with laser light energy excitation of the oxygen to ozone comprising the steps of: selecting an inert dielectric liquid not chemically reactive with ozone; injecting said liquid under superatmospheric pressure through a venturi type injector, thereby causing oxygen to be received through an entry nozzle directly into the venturi throat area and mixing with the inert liquid where it is absorbed; projecting a beam of laser light energy into the venturi throat area into the liquid pregnant with absorbed oxygen, thus converting a part of the absorbed oxygen to absorbed zone, and causing the laser light energy to be reflected back into the liquid for greater efficiency.
Claim 3
Dependent Claim
17 words
The method of claim 1 wherein a cooling fluid is circulated for temperature control of the liquid.
Claim 4
Dependent Claim
26 words
The method of claim 1 wherein the ozone and unconverted oxygen are recovered by lowering the superatmospheric pressure of the liquid to atmospheric or subatmospheric pressure.
Claim 5
Dependent Claim
15 words
The process of claim 10 wherein air is absorbed as the source of the oxygen.
