Claims Analysis

Claim 1
Independent Claim
146 words
THE METHOD OF TREATING CONTINUOUS LENGTHS OF MATERIAL WITH AN ATMOSPHERE COMPRISING THE VAPOR OF A LIQUID REAGENT REACTIVE WITH SAID MATERIAL TO FORM A REACTION BY-PRODUCT LIGHTER THAN SAID ATMOSPHERE COMPRISING CONTINUOUSLY INTRODUCING AN AEROSOL DISPERSION OF LIQUID PARTICLES OF SAID REAGENT DISPERSED IN A GAS INTO A LOWER PORTION OF A REACTION CHAMBER, THEREBY FORMING A GASEOUS REACTANT MIXTURE COMPRISING A MIXTURE OF SAID GAS AND VAPORS OF SAID REAGENT HAVING LIQUID PARTICLES OF SAID REAGENT DISPERSED THEREIN, AND CAUSING SAID REACTANT MIXTURE TO FLOW CONTINUOUSLY UPWARDLY WITHIN SAID CHAMBER, CONTINUOUSLY PASSING SAID MATERIAL THROUGH A REACTION ZONE WITHIN SAID CHAMBER ABOVE SAID LOWER PORTION SUCH THAT SAID MATERIAL CONTACTS THE UPWARD FLOW OF SAID REACTANT MIXTURE, AND CONTINUOUSLY EXHAUSTING SPENT REACTANT MIXTURE FROM SAID CHAMBER AFTER ITS CONTACT WITH SAID MATERIAL, WHEREBY THE CONCENTRATION OF SAID REACTION BYPRODUCT IS MAINTAINED AT A MINIMUM.
