摘要:
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. For the purpose of said discharge, there is used a device which comprises a pressureproof container, a pressureproof receptacle and a valve through the medium of which said pressureproof container and said pressureproof receptacle are connected, said pressureproof receptacle being provided in the upper portion thereof with a piston adapted so as to have the motion thereof limited via a valve by means of a spring and in the inner portion thereof with a liquid discharge tube laid past a piston and a valve.

An apparatus for the transfer of powder into a high-pressure vessel comprises a cylinder, two pistons disposed one on top of the other inside said cylinder and two openings formed in the circular wall of the cylinder, the one opening serving as an inlet for entry of the powder and the other opening serving as an outlet for exit of the powder into the high-pressure vessel. The transfer of powder from the powder hopper into the high-pressure vessel by use of said apparatus is accomplished by a method which comprises connecting the inlet of said apparatus to the discharge tube of the powder hopper and the outlet of the apparatus to the powder lead tube of the high-pressure vessel respectively, driving the two pistons so as to interpose a space therebetween communicating with the inlet opening, then moving the pistons in unison for thereby causing said space to move down the cylinder interior to a position in communication with the outlet opening so that the powder in the space can fall into the high-pressure vessel and then driving the pistons together to eliminate the space between them.
