Abstract

1,187,457. Ejectors. PHILIPS' GLOEILAMPENFABRIEKEN N.V. June 28, 1967 [July 1, 1966], No.29782/67. Heading F1E . [Also in Division F4] An ejector for use in a refrigerating and/or gas liquefying apparatus (see Division F4) is made of, or has part or the whole of its jet pipe 23 made of, heat insulating material, e.g. glass or synthetic material, to increase it efficiency by preventing heat conduction along the surfaces in contact with the inducing fluid, e.g. helium.
