Abstract
434,193. Obtaining rare gases. VEREINIGTE GLUHLAMPEN UND ELECTRICITATS AKT.-GES., Ujpest, near Budapest. Jan. 1, 1934, No. 62. Convention date, July 15, 1933. [Class 8 (ii)] Krypton and other atmospheric constituents less volatile than oxygen are obtained by partial liquefaction of air, the krypton being washed out by liquid air or nitrogen at a temperature lower than that of liquid oxygen at the pressure employed, the krypton &c. being thus obtained as a mixture with oxygen which is worked up to separate krypton &c., while the nitrogen and oxygen pass off together as gas. The Specification as open to inspection under Sect. 91 describes a process and apparatus forming the subject of Specification 434,194. This subject-matter does not appear in the Specification as accepted.
