ABSTRACT:
A small container is filled with a mixture of oxygen and nitrogen in a predetermined and precise concentration from a source of liquid oxygen and liquid nitrogen automatically, safely, and without the possibility of a human error. The empty weight is verified. Liquid oxygen is directed to vessel. When the mass of liquid oxygen is stabilized at a preset value, liquid flow is stopped. A second pipe is cooled using liquid nitrogen, by emptying through this pipe to the atmosphere liquid nitrogen. The vessel is filled with liquid nitrogen, until the vessel is full. The correct proportion of oxygen
itrogen is controlled.
