Claim 1
Independent Claim
127 words
THE METHOD OF CONTINUOUSLY SENSING THE PARTIAL PRESSURE OF OXYGEN IN ONE OF A NATURAL AND A SYNTHETIC ATMOSPHERE FOR ENVIRONMENTAL CONTROL BY UTILIZING THE HEAT OF THE OXYGEN-HYDROGEN REACTION WHICH COMPRISES THE STEPS OF SUPPLYING SAID HYDROGEN AT A PREDETERMINED PRESSURE IN SUFFICIENT QUANTITY OF REACT ALL OF THE OXYGEN IN A SAMPLE OF SAID ATMOSPHERE, METERING SAID HYDROGEN AT A PREDETERMINED RATE TO INSPIRATE SAID ATMOSPHERE, CONTINUOUSLY HOMOGENEOUSLY MIXING SAID HYDROGEN AND SAID ATMOSPHERE IN A VOLUMETRIC RATIO SUBSTANTIALLY EQUAL TO A PREDETERMINED VALUE, DIFFUSING THE MIXED GASES TO A PALLADIUM CATALYST, CATALYTICALLY REACTING ALL OF SAID OXYGEN OF SAID ATMOSPHERE WITH SAID HYDROGEN BY MEANS OF EXPOSURE TO SAID PALLADIUM CATALYST, AND CONTINUOUSLY SENSING THE HEATING OF REACTION AS A VARIATION IN TEMPERATURE GRADIENT.
