[Class 2 (iii)] Mono-halogenated unsaturated ketones containing a sterol nucleus are prepared by oxidizing the hydroxyl group in 3-position of a dihalide of a #<5>.<6> unsaturated alcohol containing a sterol nucleus to a keto group, and eliminating one molecular proportion of hydrogen halide from the dihalogenated ketone thus obtained. The removal of hydrogen halide is effected by the action of a mildly acting agent such as pyridine, dimethyl-aniline and the alkali salts of organic acids. In examples (1) trans-dehydroandrosterone is brominated in glacial acetic acid solution, oxidized with chromic acid and the product treated with anhydrous sodium acetate to give 6-bromo- #<4>.<5>-androstene-dione-(3 : 17). (2) #<5>.<6>-androstene-diol-17-mono-benzoate is brominated and oxidized as in example (1) to give dibromotestosterone benzoate which is then treated with sodium acetate to give 6-bromotestosterone benzoate. The same reaction may be applied to compounds of pregnane series such as 5 :6-dibromopregnene-ol-(3)-one-(20).

Void [Abridged as open to inspection under Sect. 91 of the Acts, Feb. 21, 1932]. [Class 39 (i).] In making incandescent cathodes for radio valves, Rontgen-ray tubes, rectifiers, &c. by treating a conducting or non-conducting core with alkaline-earth metal vapour such as barium, the core is given a preliminary coating of compounds from one or more of the following groups : (1) oxygen compounds of metals of high melting-point in such a state of oxidation that reaction with the vapour does not produce alkaline earth salts containing the metal of high melting - point in the acid radical; (2) phosphorus, arsenic, nitrogen, and like compounds of metals producing similar compounds of alkaline earth metals on reaction with the vapour, and (3) iso- or hetero-polyacids containing tungsten, molybdenum, arsenic, phosphorus, vanadium or other elements of the fifth group of the periodic system, these acids reacting with the vapour to form alkaline earth oxides, arsenides, phosphides, &c. or mixtures of these. The preferred compounds of group (1) are the lower oxides of tungsten, molybdenum, chromium and vanadium, particularly tungsten dioxide or pentoxide, molybdenum dioxide and vanadium dioxide or tetroxide. The vapour reacts with these to form alkaline earth oxide and free metal. The latter acts as a binding agent for the oxide and may alloy with the excess of alkaline earth metal. The compounds and any metal resulting from reaction with the vapour have low vapour tensions in vacuo. The final coating may be a mixture of barium and barium oxide containing an excess of barium. The compounds may be applied in monomolecular layers and from solutions or by reactions. The alkaline earth vapour may be produced by heating the metal or the azide or suboxide. Prior processes of treating with barium a tungsten core oxidized to form the trioxide are referred to.
