Executive summary: Collins-type cryocooler

At MIT in 1946, Samuel C. Collins designed and constructed the Collins Helium Cryostat, the first practical helium liquefier. The machine, a two-cylinder engine with the cold exhaust from one cylinder cooling the intake gas of the other cylinder, allowed the production of liquid helium without external coolants, and enabled affordable experiments in temperatures descending to near absolute zero. Within a decade more than 200 of the machines were installed in laboratories worldwide. Collins also invented a device for producing high purity oxygen, and an early heart-lung machine used in emergency and rescue operations.
