Abstract
1324918 Refrigerating LEYBOLD-HERAEUS-VERWALTUNG GmbH 12 Oct 1971 [13 Oct 1970] 47536/71 Heading F4H A process for the continuous production of low temperatures, especially below 4À2‹K, by expansion of compressed helium gas, wherein He is compressed to above 550 mm. Hg. and expanded in an expansion chamber, in a closed cycle, and wherein the compressed He<SP>3</SP> is precooled before expansion by passing it in heat exchange relationship with a bath of liquid helium at atmospheric pressure.
