Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
118 words
GAS ANALYSIS APPARATUS COMPRISING A VESSEL ADAPTED TO CONTAIN A TEST FLUID, CONDUIT MEANS COMMUNICATING AT ONE END WITH THE INTERIOR OF SAID VESSEL TO INTRODUCE GAS TO BE ANALYZED INTO SAID VESSEL, PRESSURE REGULATING MEANS ASSOCIATED WITH SAID CONDUIT MEANS TO MAINTAIN A PREDETERMINED PRESSURE THEREIN, TEMPERATURE REGULATING MEANS ASSOCIATED WITH SAID CONDUIT MEANS TO MAINTAIN A PREDETERMINED TEMPERATURE THEREIN, FLOW MEASURING MEANS ASSOCIATED WITH SAID CONDUIT MEANS TO MEASURE THE FLOW OF GAS THERETHROUGH, MEANS TO DETECT A CHANGE IN THE TEST FLUID WITHIN SAID VESSEL WHEN CONTACTED WITH A PREDETERMINED VOLUME OF THE GAS TO BE ANALYZED, AND MEANS RESPONSIVE TO SAID MEANS TO DETECT TO TERMINATE THE FLOW OF GAS THROUGH SAID CONDUIT MEANS.

Claim 3
Independent Claim
83 words
THE METHOD OF MEASURING THE CONCENTRATION OF ACETYLENE IN A GASEOUS MIXTURE WHICH COMPRISES POSITIONING AN AQUEOUS SOLUTION OF SILVER NITRATE CONTAINING A BUFFERING AGENT IN A CONTACTING ZONE, AND PASSING THE GASEOUS FLUID TO BE MEASURED INTO SAID ZONE UNTIL THE PH OF THE SOLUTION FALLS TO A PREDETERMINED VALUE, WHEREBY THE ACETYLENE CONCENTRATION IN THE GASEOUS FLUID TO BE MEASURED CAN BE DETERMINED FROM THE VOLUME OF GASEOUS FLUID REQUIRED TO LOWER THE PH OF THE SOLUTION TO SAID PREDETERMINED VALUE.
