Abstract: 733,385. Generating combustion products under pressure. BRITISH THOMSONHOUSTON CO., Ltd. Feb. 17, 1954 [Feb. 17, 1953], No. 4416/53. Class 51 (1). In an arrangement for the production of a flow of working fluid by decomposition of a monofuel comprising a main reaction chamber 1, in which the greater part of the fuel injected  at 4, is decomposed to form a flow of fluid through an outlet 5, and an auxiliary reaction chamber 2 in which combustion of a separate supply of monofuel takes place to produce a flow of heated gas into the main chamber to induce decomposition of the fuel therein, the flow of gas from the auxiliary chamber at 3 passes into the main chamber through shrouding means 6 which projects into the main chamber and in which the gas meets a jet 9 of monofuel, the resulting combustion products flowing out of the shrouding means through an aperture 6c at or near its inner end. In a modification of the arrangement shown, the shrouding 6 is open at its inner end, and the jet 9 is directed axially along it in opposition to the gas stream. Apertures 7 are preferably provided to allow circulation of fuel from the chamber 2 and consequent turbulence of flow in that chamber. The arrangement results in the high-temperature fuel-gas combination circulating in the inner part of the chamber 2, with reduced loss of heat to the walls. Specification 726,897 is referred to.

On treatment of the 1a -substituted products with a mineral acid in a lower aliphatic alcohol there are produced the corresponding 1a -substituted-D 4-3-keto-steroids. If a 17-keto-starting material is used in the Grignard process a 17a -substituted-17b -ol is obtained.  If an alkali metal cyanide replaces the Grignard reagent in the first-described process the 1a -cyano-5, 10-methylene-19-nor-3-keto compounds are produced exclusively, which, by acid treatment as described, give the 1a -cyano-D 4-3-keto-steroids. In this last instance the 20-keto group does not require protection.  Protected side chains are hydrolysed by conventional methods.  A hydroxyl group may be introduced at C-11 by incubation with adrenal glands or Curvularia lunata.  The 11-ols, in which the 21-hydroxy group is protected by acylation, on oxidation give the 11-ones.  Hydroxy groups in the products are esterified by conventional methods.  20 - Ethylenedioxy - 5,10 - methylene - 19 - nor-D 1-pregnen -3-one is prepared by oxidizing 20 - ethylenedioxy - D 5 - pregnene - 3b ,19 - diol (prepared by ketalization of the 20-one) to 20 - ethylenedioxy - D 4 - pregnen - 19 - ol - 3 - one and reacting this with 2-chloro-1,1,2-trifluorotriethylamine, another product being 20-ethylenedioxy - 5,10 - seco - 5,19 - cyclo - 10b -fluoro-D 4-pregnen-3-one The corresponding 17a -ol acetates and 16a - and 16b -methyl compounds and the 17a -ol acetates of the last-named are prepared similarly.  16a  - Methyl - 17,20;20,21 - bismethylenedioxy-5, 10 - methylene - 19 - nor - D 1 - pregnen - 3 - one is prepared by ketalization of the 17a ,21-diol-20-one.
