Helium appears indispensable for certain energy-related uses that may be important 50 years from now, when helium-bearing natural gas, a much cheaper source than air, may be exhausted. Present demand, however, is lower than productive capacity, and much helium is being dissipated into the atmosphere as natural gas is burned for fuel.

Physical Review, 1946
A helium cryostat which is cooled by the isentropic expansion of helium without the aid of liquid air or other refrigerant provides a cold chamber for experiments at any temperature down to 2°K. Any gas can be liquefied and delivered to external receivers as desired. Three expansion devices are described. One is a diaphragm engine having a mechanically
