Title: Filter or separator pad of knitted fabric - having certain courses of a different yarn so that the fabric forms corrugations
IPC: B01D39/12
Filed: 1973-07-23
Abstract: A filter or separator pad is formed from a knitted fabric having certain courses formed by a different, pref. more flexible, yarn than the yarns forming the other courses, so that the fabric forms corrugations with the troughs extending along the courses of more flexible yarn.

Title: Glass fibre production - in crucible with loose bottom plate both of which float in glass permeated lining
IPC: C03B37/08
Filed: 1974-01-30
Abstract: Glass fibre making plant comprises a glass melting vessel consisting of a sleeve with open bottom standing on a perforated bottom plate through which the molten glass passes to form a bundle of glass fibres on solidification.
