Apparatus for analyzing gas

Claim 1

AN APPARATUS FOR ANALYZING A GAS CONTAINING UNCONDENSED WATER VAPOR AND CONTAMINATED WITH FREE MOISTURE AND FINELY DIVIDED SOLIDS COMPRISING, IN COMBINATION, A SAMPLING LINE CONNECTED TO A SUPPLY OF THE GAS TO BE ANALYZED, AN ELIMINATOR OF NONGASEOUS CONTAMINANTS, AND ELIMINATOR BEING CONNECTED TO SAID SAMPLING LINE AND SEPARATING OUT SUCH NONGASEOUS CONTAMINANTS BY UTILIZING THEIR GREATER INERTIA, A MOISTURE TRAP CONNECTED BELOW SAID ELIMINATOR, A FILTER CONNECTED IN SERIES WITH SAID ELIMINATOR FOR RECEIVING GAS THEREFROM AND REMOVING FINELY DIVIDED SOLIDS FROM THE GAS, MEANS FOR HEATING THE GAS PASSING THROUGH SAID FILTER AT A TEMPERATURE ABOVE THE DEWPOINT OF THE GAS, AN ANALYZER CONNECTED BY MEANS OF A CONDUIT TO SAID FILTER TO RECEIVE FROM SAID FILTER THE DECONTAMINATED GAS WHILE SO HEATED ABOVE ITS DEWPOINT, AN ELECTRICALLY OPERATED VALVE TO CLOSE AND OPEN SAID CONDUIT, A THERMOSWITCH INCORPORATED WITH SAID FILTER AND ELECTRICALLY CONNECTED TO SAID ELECTRICALLY OPERATED VALVE TO CAUSE SAID VALVE TO CLOSE SAID CONDUIT WHEN THE TEMPERATURE WITHIN SAID FILTER IF BELOW THE DEWPOINT OF THE GAS, SAID ANALYZER BEING ADAPTED TO ANALYZE THE GAS WITH ITS CONTENT OF UNCONDENSED WATER VAPOR REMAINING THEREIN, AND MEANS FOR MOVING THE GAS SUCCESSIVELY THROUGH SAID SAMPLING LINE, SAID ELIMINATOR, SAID FILTER AND SAID ANALYZER.

Claim 2

AN APPARATUS FOR ANALYZING A GAS CONTAINING UNCONDENSED WATER VAPOR AND CONTAMINATED WITH FREE MOISTURE AND FINELY DIVIDED SOLIDS COMPRISING, IN COMBINATION, A SAMPLING LINE CONNECTED TO A SUPPLY OF THE GAS TO BE ANALYZED, AN ELIMINATOR OF NONGASEOUS CONTAMINANTS, AND ELIMINATOR BEING CONNECTED TO SAID SAMPLING LINE AND SEPARATING OUT SUCH NONGASEOUS CONTAMINANTS BY UTILIZING THEIR GREATER INERTIA, A MOISTURE TRAP CONNECTED BELOW SAID ELIMINATOR, A FILTER CONNECTED IN SERIES WITH SAID ELIMINATOR FOR RECEIVING GAS THEREFROM AND REMOVING FINELY DIVIDED SOLIDS FROM THE GAS, MEANS FOR HEATING THE GAS PASSING THROUGH SAID FILTER AT A TEMPERATURE ABOVE THE DEWPOINT OF THE GAS, AN ANALYZER CONNECTED BY MEANS OF A CONDUIT TO SAID FILTER TO RECEIVE FROM SAID FILTER THE DECONTAMINATED GAS WHILE SO HEATED ABOVE ITS DEWPOINT, AN ELECTRICALLY OPERATED VALVE TO CLOSE AND OPEN SAID CONDUIT, A THERMOSWITCH INCORPORATED WITH SAID FILTER AND ELECTRICALLY CONNECTED TO SAID ELECTRICALLY OPERATED VALVE TO CAUSE SAID VALVE TO CLOSE SAID CONDUIT WHEN THE TEMPERATURE WITHIN SAID FILTER IF BELOW THE DEWPOINT OF THE GAS, SAID ANALYZER BEING ADAPTED TO ANALYZE THE GAS WITH ITS CONTENT OF UNCONDENSED WATER VAPOR REMAINING THEREIN, AND MEANS FOR MOVING THE GAS SUCCESSIVELY THROUGH SAID SAMPLING LINE, SAID ELIMINATOR, SAID FILTER AND SAID ANALYZER.
