  • Method for discharging high-pressure gas-occluding liquid and device therefor
    Patent number: 4138035
    Abstract: Discharge of a high-pressure gas-occluding liquid from a pressureproof container holding therein said liquid in a compressed state is effected by a method which comprises connecting said pressureproof container through the medium of a valve to a pressureproof receptacle, allowing the liquid to transfer into said pressureproof receptacle, diminishing the pressure within said pressureproof receptacle for thereby separating the occluded high-pressure gas from the liquid and subsequently releasing the liquid alone from the receptacle.
