Abstract

1,066,348. Mould and core materials. VEREIN ZUR FÍRDERUNG GIESSEREI INDUSTRI. Oct. 9, 1964 [Oct. 10, 1963; Oct. 16, 1963], No. 41413/64. Heading B3F. Natural or synthetic moulding sands having a quartz sand base with conventional binders have added to them, separately or premixed, a carbonaceous substance with a softening index, as defined in the Specification, of between 0À2 and 0À7 and a further carbonaceous substance which has more than 50% volatile components, e.g. brown coal, peat, sawdust. The first carbonaceous substance may be a mixture of coal dust and bitumen.
