Claim 3
Independent Claim
77 words
A METHOD FOR AUTOMATICALLY CONTROLLING THE ADDITION OF FRESH OXYGEN-ABSORBING MATERIAL TO AN AT LEAST PARTIALLY SPENT OXYGEN-ABSORBING MATERIAL WHICH COMPRISES, CONTACTING A SAMPLE OF THE AT LEAST PARTIALLY SPENT OXYGEN ABSORBING MATERIAL WITH OXYGEN UNDER CONDITIONS SUCH THAT SAID SAMPLE IS COMPLETELY REACTED WITH OXYGEN MEASURING THE AMOUNT OF OXYGEN REQUIRED FOR SAID COMPLETE REACTION, ANDF IN ACCORDANCE THEREWITH, AUTOMATICALLY CONTROLLING THE ADDITION OF FRESH OXYGEN ABSORBING MATERIAL TO THE AT LEAST PARTIALLY SPENT OXYGEN-ABSORBING MATERIAL.
