ABSTRACT:
A compact, portable cryogenic system for powering portable gas-driven tools having a container which includes an outer vacuum casing and an inner container with each having small, openings at their top connected together forming an evacuable space between the outer casing and the inner container. Material to inhibit heat transfer through the evacuable space is included in the space between the outer casing and the inner container. The openings of the inner container are closed with gas-tight closures fastened to the outer vacuum casing. The gas-tight closures can carry, through the single openings in the inner container, means to admit cryogenic liquid or withdraw cryogenic liquid from the inner container and means to admit heat to the inner container as may be desired. Warming coils positioned on the outer vacuum casing of the container communicate with the inner container and the flow of gas from the warming coils may be controlled by an adjustable pressure regulator.
