Oxygen diffusion analyzer

Claim 1

IN A GALVANIC CELL FOR ANALYSIS OF OXYGEN IN A GAS MIXTURE STREAM, SAID CELL COMPRISING IN COMBINATION: (A) A CONTAINER HAVING A RESTRAINING WALL, SAMPLE GAS STRAM INLET AND OUTLET MEANS, AN ELECTROLYTE POOL AND ELECTRODE ASSEMBLY SUPPORTING MEAMS; (B) AN ELECTRODE ASSEMBLY SO ARRANGED AND CONSTRUCTED SO AS TO BE SUPPORTED WITHIN SAID CONTAINER IN SUCH MANNER AS TO BE DIRECTLY CONTACTED BY SAID SAMPLE GAS STREAM FROM SAID SAMPLE GAS STREAM INLET MEANS, SAID ELECTRODE ASSEMBLY COMPRISING IN COMBINATION A SERIES OF CONTIGUOUS, CONCENTRIC CYLINDRICAL ELEMENTS WHEREIN SAID ELEMENTS COMPRISE IN RESPECTIVE ORDER FROM THE EXTERNAL SURFACE: (1) A FIRST ELECTRODE REACTABLE WITH OXYGEN; (2) A FIRST ABSORBENT LAYER; (3) NONPOROOUS, INERT AND ELECTRICALLY INSULATING DIFFUSION BRRIER MEANS; (4) A SECOND ABSORBENT LAYER, WHICH LAYER CONTCTS SAID FIRST ABSORBENT LAYER FOR AT LEAST A PORTION OF ITS SURFACE AREA; (5) A SECOND ELECTRODE; (C) AN ELECTROLYTE POOL WHICH POOL IS IN CONTCT WITH A PORTION OF SAID FIRST AND SECOND ABSORBENT LAYERS SO AS TO CAUSE THESE LAYERS TO BE WETTED BY THE ELECTROLYTE; (D) CURRENT MEANS ADAPTED TO RECEIVE CURRENT GENERATED BY SAID FIRST AND SECOND ELECTRODES WHEN OXYGEN IS PRESENT IN THE CELL; WHERIN SAID FIRST ELECTRODE IS NOT REACTABLE WITH SAID ELECTROLYTE AT ANY TIME AND SAID SECOND ELECTRODE IS REACTABLE ONLY WHEN OXYGEN IS PRESENT IN THE CELL; THE IMPROVEMENT COMPRISING UTILIZING ACETIC ACID AS THE ELECTROLYTE, SAID ACETIC ACID ELECTROLYTE BEING COVERED WITH A RELATIVELY THIN LAYER OF A MINERAL OIL WHERIN THE RESPONSE TIME OFF THE CELL IS IMPROVED.
