Abstract

286,915. Fraser, A., and Rissik, Fraser, & Co., Ltd. Nov. 2, 1926. Moulds; moulding ebonite.-In the process of moulding ebonite articles by subjecting ebonite dust to pressure and heat, moulds are employed, the inner surfaces of which are composed of materials to which the dust will not stick, and with which the dust will not react at the temperature employed. The mould may be made, or lined with tin, brass, duralumin, or other alloys of aluminium, or an alloy such as is described in Specification 250,721, [Class 82 (i), Metals, Extracting &c.], or a rustless steel containing no nickel. Moulds plated with suitable metals may also be employed. Specification 273,355 is referred to.
