Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
176 words
IN APPARATUS FOR PRODUCING LIQUID OZONE: A CEMPRESSOR ADAPTED TO COMPRISESS AIR ABOVE THE CRITICAL PRESURE THEREOF; A LIQUID AIR PLANT INCLUDING A PRECOOLER CONNECTED TO THE OUTPUT OF SAID COMPRESSOR AND ADAPTED TO LIQUEFY AIR DELIVERED BY SAID COMPRESSOR; A FRACTIONATING COLUMN CONNECTED TO RECIVE LIQUID AIR FROM SAID PLANT AND ADAPTED TO SEPARATE THE SAME INTO GASEOUS NITROGEN AND LIQUID OXYGEN; A BOILER OF SAID LIQUID OXYGEN, SAID AT A POINT THERIN TO RECIEVE SAID LIQUID OXYGEN, SAID BOILER BEING ADAPTED TO MAINTAIN A PRESSURE THEREIN TO EFFECT CONTROLLED BOILING OF SAID LIQUID OXYGEN SAID DELIVER GASEOUS OXYGEN THEREFROM UNDER PRESSURE; AN AZONE GENERATOR CONNECTED BY A CONDUIT OT SAID BOILER TO RECEIVE SAID GASEOUS OXYGEN AND CONVERT A SUBSTANTIAL PROPERTION THEREOF INTO GASEOUS OZONE; AND A BEAT EXCHANGER ELEMENT IN SAID BOILER CONNECTED TO RECEIVE FROM SAID GENERATOR, GASEOUS OZONE MIXED WITH UNCONVERTED GASEOUS OXYGEN, SAID ELEMENT BEING IN HEAT EXCHANGE RELATION WITH SAID BOILING OXYGEN WHEREBY TO LIQUEFY SAID OZONE WHILE DELIVERING THE HEAT OF CONDENSATION PRODUCTED THEREBY TO SAID BOILING OXYGEN.

IN APPARATUS FOR PRODUCING LIQUID OZONE: A CEMPRESSOR ADAPTED TO COMPRISESS AIR ABOVE THE CRITICAL PRESURE THEREOF; A LIQUID AIR PLANT INCLUDING A PRECOOLER CONNECTED TO THE OUTPUT OF SAID COMPRESSOR AND ADAPTED TO LIQUEFY AIR DELIVERED BY SAID COMPRESSOR; A FRACTIONATING COLUMN CONNECTED TO RECIVE LIQUID AIR FROM SAID PLANT AND ADAPTED TO SEPARATE THE SAME INTO GASEOUS NITROGEN AND LIQUID OXYGEN; A BOILER OF SAID LIQUID OXYGEN, SAID AT A POINT THERIN TO RECIEVE SAID LIQUID OXYGEN, SAID BOILER BEING ADAPTED TO MAINTAIN A PRESSURE THEREIN TO EFFECT CONTROLLED BOILING OF SAID LIQUID OXYGEN SAID DELIVER GASEOUS OXYGEN THEREFROM UNDER PRESSURE; AN AZONE GENERATOR CONNECTED BY A CONDUIT OT SAID BOILER TO RECEIVE SAID GASEOUS OXYGEN AND CONVERT A SUBSTANTIAL PROPERTION THEREOF INTO GASEOUS OZONE; AND A BEAT EXCHANGER ELEMENT IN SAID BOILER CONNECTED TO RECEIVE FROM SAID GENERATOR, GASEOUS OZONE MIXED WITH UNCONVERTED GASEOUS OXYGEN, SAID ELEMENT BEING IN HEAT EXCHANGE RELATION WITH SAID BOILING OXYGEN WHEREBY TO LIQUEFY SAID OZONE WHILE DELIVERING THE HEAT OF CONDENSATION PRODUCTED THEREBY TO SAID BOILING OXYGEN.
Claim 3
Independent Claim
96 words
THE METHOD OF PRODUCING LIQUID OZONE WHICH IN CLUDES THE STEPS OF: COMPRESSING SAID COOLING AIR TO PRODUCE LIQUID AIR; FRACTIONATING SAID LIQUID AIR TO SEPARATE SAID LIQUID AIR; INTO GASEOUS NITROGEN AND LIQUID OXYGEN PASSING SAID LIQUID OXYGEN INTO A BOILER WHEREBY TO VAPORIZE SAME; THEREAFTER PASSING SAID VAPORIZED OXYGEN THROUGH A CORONA DISCHARGE WHEREBY TO OZONIZE SAID OXYGEN; AND THEREAFTER PASSING SAID OZONIZED OXYGEN IN HEAT EXCHANGE RELATION THROUGH SAID BOILER WHEREBY TO TRANSFER HEAT FROM SAID OZONIZED OXYGEN TO SAID LIQUID OXYGEN, LIQUEFY OZONE IN SAID OZONIZED OXYGEN, AND VAPORIZE SAIL LIQUID OXYGEN.
Claim 4
Independent Claim
96 words
THE METHOD OF PRODUCING LIQUID OZONE WHICH IN CLUDES THE STEPS OF: COMPRESSING SAID COOLING AIR TO PRODUCE LIQUID AIR; FRACTIONATING SAID LIQUID AIR TO SEPARATE SAID LIQUID AIR; INTO GASEOUS NITROGEN AND LIQUID OXYGEN PASSING SAID LIQUID OXYGEN INTO A BOILER WHEREBY TO VAPORIZE SAME; THEREAFTER PASSING SAID VAPORIZED OXYGEN THROUGH A CORONA DISCHARGE WHEREBY TO OZONIZE SAID OXYGEN; AND THEREAFTER PASSING SAID OZONIZED OXYGEN IN HEAT EXCHANGE RELATION THROUGH SAID BOILER WHEREBY TO TRANSFER HEAT FROM SAID OZONIZED OXYGEN TO SAID LIQUID OXYGEN, LIQUEFY OZONE IN SAID OZONIZED OXYGEN, AND VAPORIZE SAIL LIQUID OXYGEN.
