776,417. Cold separation of gases. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. July 21, 1955 [July 24, 1954], No. 21151/55. Class 8(2) In a device for condensing water and carbon dioxide from air comprising apertured plates 14 which extend laterally from a carrier 13 to a wall 16 so as to provide a heat exchanger having one end maintained colder than the other e.g. by means of a gas refrigerator of the re versed hot gas engine type, the apertures 15 which are staggered with respect to adjacent plates 14 are so dimensioned as to allow passage through each of them of at least 0.1 gm. of air per second at a mean velocity of at least 5 cms. per second, the temperature gradient of the plates is not more than 20‹C. and the temperature of the particular plate on which condensation commences is not more than 20‹C. below the freezing.point of the separated constituent. Specification 746,436 is referred to. |
