Gas sterilizing system
First Claim
1. AN ETHYLENE OXIDE-CARBON DIOXIDE STERILIZER SYSTEM, COMPRISING A HIGH PRESSSURE CYLINDER CONTAINING EHTYLENE OXIDE AND CARBON DIOXIDE IN BOTH GAS AND LIQUID PHASE WITH THE EHTYLENE OXIDE CONCENTRATION BEING GREATER IN THE LIQUID PHASE, EDUCTOR MEANS FROM DISCHARGING FROM THE CYLINDER A MIXTURE OF THE GAS AND LIQUID PHASE FOR MAINTAINING THE DESIRED RATIO OF EHTYLENE OXIDE AND CARBON DIOXIDE WHEN THE AMOUNT WITHDRAWIN EXCEEDS A PREDETERMINED MINIMUM QUANTITY, AN EXPANSION TANK OF VOLUME SMALLER THAN THAT REQUIRED TO HOLD THE ENTIRE CONTENTS OF A CYLINDER IN GAS PHSE, AN INLET LINE CONNECTING THE EDUCTOR MEAND AND TANK, A HEAT EXCHANGER IN SAID LINE FOR CONVERTING THE LIQUID PHASE TO GAS, A VALVE IN SAID LINE MEANS RESPONSIVE TO THE PRESSURE IN THE EXPANSION TANK FOR OPENING THE VALVE AT A LOW LIMIT AND CLOSING THE VALVE AT AN UPPER LIMIT OF THE EXPANSION TANK PRESSURE, THE PRESSURE IN SAID EXPANSION TANK INCREASING LESS THAN THE DIFFERENCE BETWEEN SAID UPEPR LIMIT AND SAID LOWER LIMIT UPON ADDITION OF SAID MINIMUM QUANTITY, MEANS FOR MAINTAINING THE TEMPERATURE OF THE TANK ABOVE THAT AT WHICH CONDENSATION TAKES PLACE, AN OUTLET LINE LEADING TO A STERILIZER CHAMBER, AND A VALVE IN THE OUTLET LINE FOR CONTROLLING THE SUPPLY OF GAS TO THE STERILIZER CHAMBER.
