Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
127 words
THE METHOD OF MEASURING THE AMOUNT OF MOLECULAR OXYGEN IN A SAMPLE OF GAS CONSUMED IN A PROCESS, COMPRISING THE STEPS OF EXPOSING A SAMPLE OF THE GAS BEFORE USE TO ELECTROMAGNETIC ENERGY OF A CRITICAL WAVE LENGHT CHARACTERISTIC OF OXYGEN, AT WHICH A STRONGLY SELECTIVE ABSORPTION OF SAID ENERGY OCCURS USING THE SAMPLE IN THE PROCESS, EXPOSING THE SAMPLE OF THE GAS AFTER USE TO ELECTROMAGNETIC ENERGY OF THE SAID CRITICAL WAVE LENGHT AND MEASURING AND RECORDING THE ENERGY PASSED THROUGH THE GAS TO GIVE MEASUREMENTS THAT MAY BE COMPARED TO DETERMINE THE DIFFERENCE IN ABSORPTION OF THE ENERGY BY THE SAMPLE BEFORE AND AFTER IT IS SUBJECTED TO THE PROCESS, THUS GIVING AN INDICATION OF THE PROPORTION OF THE MOLECULAR OXGYEN CONSUMED IN THE PROCESS.
Claim 2
Independent Claim

Claim 3
Dependent Claim
106 words
APPARATUS FOR DETERMINING THE CONSUMPTION OF MOLECULAR OXYGEN IN A SAMPLE OF GAS USED IN A PROCESS, COMPRISING: MEANS FOR GENERATING ELECTROMAGNETIC ENERGY OF A CRITICAL WAVE LENGHT, CHARACTERISTIC OF OXYGEN, AT WHICH A STRONGLY SELECTIVE ABSORPTION OF SAID ENERGY OCCURS, A CHAMBER ADAPTED TO CONTAIN A SAMPLE OF GAS, MEANS TO INTRODUCE THE SAMPLE OF GAS INTO THE CHAMBER BEFORE AND AFTER USE IN THE PROCESS, MEANS FOR PROPAGATING SAID ENERGY THROUGH SAID CHAMBER BEFORE AND AFTER THE GAS IS USED, AND LASTING RECORD PRODUCING MEANS FOR INDICATING THE AMOUNT OF ELECTROMAGNETIC ENERGY TRANSMITTED THROUGH THE SAMPLE BOTH BEFORE AND AFTER THE GAS IS USED.
