Abstract

242,617. Compagnie GÚnÚrale des Conduits d'Eau. Nov. 4, 1924, [Convention date]. Mould materials.-Moulds are coated internally, wholly or in part, with silicon or a compound thereof with a metal to reduce the conductivity of the mould wall and to increase the tendency of the iron carbide at the surface of the casting to decompose due to dissolved silicon. Coating and lining moulds.-The Specification as open to inspection under Sect. 91 (3) (a) comprises also apparatus similar to that described in Specification 254,328 for lining centrifugal moulds and introducing the, molten metal. This subjectmatter does not appear in the Specification as accepted.
