In an earlier communication1 a description was given of the gas refrigerating machine, developed in the Philips Laboratories at Eindhoven, Holland. This new type of refrigerator was introduced as an air liquefier, but it was mentioned that it is also suitable for the production of cold in general, particularly between -80°C and -200°C. Among other applications, the separation of air into its components was cited as one of the most promising fields. The present paper deals with this subject and describes a small plant producing liquid nitrogen, utilizing the gas refrigerating machine.
