Abstract

287,164. British Maxium, Ltd. March 18, 1927, [Convention date]. Mould materials.-To protect magnesium, or its alloys, when cast into a sand mould, salts of ammonium are mixed with the sand or applied, wet or dry, to the inner surface of the mould. For instance 2 per cent of ammonium borate or fluoride may be mixed with the sand, the fluoride producing a protective film on the casting. Agglomerants, solutions of resins in oils, or other substances more easily oxidizable than magnesium may also be added to the sand. The Specification as open to inspection under Sect. 91 (3) (a) states also that the moulds may be used for casting other easily oxidizable metals. This subject-matter does not appear in the Specification as accepted.
