Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
110 words
THE METHOD OF TESTING PRESSURE IN A CLOSED PREPRESSURIZED CONTAINER CONTAINING A GAS AT AMBIENT TEMPERATURE BUT UNKNOWN PRESSURE GREATER THAN ATMOSPHERIC, WHICH COMPRISES THE STEPS OF CONFINING A TEST GAS IN A FIXED VOLUME AT AMBIENT TEMPERATURE AND AT PREDETERMINED PRESSURE GREATER THAN ATMOSPHERIC, WHICH FIXED VOLUME IS SMALL IN COMPARISON TO THAT OF THE GAS IN THE CONTAINER TO BE TESTED, THEN BRINGING SAID TEST GAS INTO PRESSURERESPONSIVE COMMUNICATION WITH SAID CONTAINER GAS, MAINTAINING SAID PRESSURE-RESPONSIVE COMMUNICATION FOR A PERIOD OF TIME SUFFICIENT TO ALLOW THE PRESSURE OF SAID TEST GAS TO REACH EQUILIBRIUM WITH SAID CONTAINER GAS PRESSURE, AND MEASURING THE RESULTANT PRESSURE OF SAID TEST GAS.

Claim 3
Dependent Claim
132 words
APPARATUS FOR TESTING PRESSURE IN A CLOSED CONTAINER HAVING A VALVED OUTLET, COMPRISING AN ENCLOSURE HAVING A TEST-GAS CHAMBER PROVIDED WITH AN INLET AND AN OUTLET, AN ADAPTER HEAD HAVING AN OPENING FOR COMMUNICATION WITH SAID TEST-GAS CHAMBER OUTLET, MEANS FOR MOVING SAID ADAPTER HEAD INTO GAS-TIGHT ENGAGEMENT WITH SAID CONTAINER WITH SAID CONTAINER OUTLET IN COMMUNICATION WITH SAID OPENING, MEANS FOR OPENING SAID TEST-GAS CHAMBER INLET TO APPLY AN EXTERNAL PRESSURE TO SAID CHAMBER, MEANS FOR CLOSING SAID INLET AFTER A PREDETERMINED PRESSURE HAS BEEN CREATED IN SAID CHAMBER, MEANS FOR OPENING SAID VALVED OUTLET OF SAID CONTAINER WHILE SAID ADAPTER HEAD IS IN ENGAGEMENT WITH SAID CONTAINER AND FOR ESTABLISHING PRESSURE-RESPONSIVE COMMUNICATION BETWEEN SAID TEST-GAS CHAMBER AND SAID CONTAINER, AND MEANS FOR INDICATING THE RESULTANT PRESSURE IN SAID TEST-GAS CHAMBER.
