Title: Process for performing chemical reactions under pressure, by means of highly heated gases
IPC: A43D21/18
Filed: 1932-10-07
Abstract: A process for performing chemical operations under pressure, such as destructive hydrogenation, or obtaining hydrogen by catalytic conversion of carbon monoxide in gaseous mixtures or for making a rich gas by the action of superheated steam in gasifying solid fuel such as coal dust, comprises heating the compressed gases or steam by indirect heat transmission in a continuously operating superheater, the heating gases being generated and passed through the superheater under approximately the same pressure as the gases that are to be heated.  This pressure may vary from 3 to 20 atmospheres.  The energy of the heating gases issuing from the superheater is utilized for example in a gas turbine, for the generation of power.  The tubes of the superheater may be made of porous material.

Title: Improvements relating to organopolysiloxanes
Filed: 1955-10-07
Abstract: Structure-inducing fillers for use in siloxane elastomers are treated with sulphur dioxide by passing the gas up through a vertically positioned tube charged with the filler.  Fillers specified are silica aerogel, fume silica (made by the vapour phase burning of SiCl4) and g -alumina.  The fillers used in the Examples, viz. calcined silica aerogel and fume silica, were charged into a chromatographic column fitted with a fritted glass bottom through which sulphur dioxide gas was blown for about 30 minutes at a rate sufficient to fluidize the bed of filler; the filler was then removed and placed in a sealed container.  The Specification also mentions the treatment of these fillers with carbon dioxide, HCl fumes, boric acid and benzoic acid.ALSO:A curable composition comprises an organopolysiloxane convertible to the solid, elastic state and containing an average of from 1.95 to 2.05 organic radicals per Si atom, and a structure-inducing silica or alumina filter which has been treated with sulphur dioxide (see Group III).  The siloxanes specified contain alkyl, alkenyl, aryl, alkaryl, aralkyl or halogenated aryl radicals.  Structure-inducing fillers specified are silica aerogel, fume silica and a -alumina, and are used in amount, e.g. of from 10 to 200 per cent by weight of the siloxane.  Other fillers that may be added are titania, lithiopone, zinc oxide, zirconium silicate, iron oxide and calcium carbonate.  Curing may be accelerated by the addition of organic peroxides, e.g. benzoyl, para-chlorobenzoyl and 2:4-dichlorobenzoyl peroxides and tertiary butyl perbenzoate, or by high energy electron irradiation.  In examples, the novel elastomers are compared with those containing untreated fillers or carbon dioxide or hydrogen chloride treated fillers.  Uses-the compositions may be used in extrusion moulding or calendering applications, or they may be dispersed in solvents and used for coating or impregnating glass tape, glass fibre sheets and asbestos cloth for making heater ducts.  Specifications 594,481,[Group IV], 618,453, 640,067, 735,807 and 772,088 are referred to.
