Claim 1
Independent Claim
129 words
THE METHOD OF PRODUCING A PREPONDERANCE OF UNIPOLAR IONS IN AN AIR SPACE, COMPRISING THE STEPS OF: PRODUCING AN ELECTRIC GLOW AND CORONA DISCHARGE IN SAID AIR SPACE BY APPLYING AN A.C. VOLTAGE TO SPACED ELECTRODES; MAINTAINING THE SPATIAL EXTENSION OF SAID GLOW AND CORONA DISCHARGE TO A FRACTION OF A MILLIMETER; HOLDING SAID A.C. VOLTAGE TO A VALUE SUCH THAT SAID GLOW AND CORONA DISCHARGE DELIVERS UP TO ABOUT 106 IONS PER SECOND TO EACH CUBIC CENTIMETER OF SAID SPACE WHILE HOLDING THE PRODUCTION OF OZONE TO NO MORE THAN 30.1-12 GRAMS PER CUBIC CENTIMETER; AND APPLYING A D.C. VOLTAGE ACROSS SAID AIR SPACE TO IMPRESS AN ELECTRIC FIELD THEREACROSS TO THEREBY WITHDRAW IONS OF THE DESIRED POLARITY FROM SAID GLOW AND CORONA DISCHARGE INTO SAID AIR SPACE.
