Commercial Handling of Liquid Helium Dewars
The commercial production and distribution of liquid helium by the industrial gas industry has grown considerably since its inception in late 1959. Liquid helium is now used extensively as a disposable refrigerant and is readily available from several commercial suppliers. The widespread usage and distribution of helium, as a liquid, across the country, have multiplied the problems of safety, neck plug hazards, and losses; it has created problems of structural durability and air transport. More versatile transfer equipment and simplified techniques are required to meet the diversification of application, and a generally lower price structure will tolerate slightly higher product losses.
