Abstract

1,228,298. Liquid metal filter. KARL SCHMIDT G.m.b.H. 24 Sept., 1969 [24 Oct., 1968], No. 47110/69. Heading BID. [Also in Division D1] A glass-fibre mesh is rendered suitable for use as a filter for use in foundry work by impregnating it with a stiffening agent and subsequently heating at 600-900‹C for 1-30 seconds. The stiffening agent may be a phenolic resin.
