Abstract
Artificial stones for making drilling and turning tools and wire-drawing dies are produced by mixing powdered tungsten or tungsten compounds with diamond dust, and heating the mixture in a closed mould in an electric arc or resistance furnace. The product is a carbide which may contain excess carbon in the form of diamond particles, particularly in the centre of the mass. Other metals such as iron and titanium may be added to the mixture before heating. The Specification, as open to inspection under Sect. 91 (3) (a), describes also the application of the process to the production of carbides of molybdenum and the difficulty fusible metals. This subject-matter does not appear in the Specification as accepted.
