Abstract

1319459 Making filter elements W R GRACE & CO 19 Jan 1971 [21 Jan 1970] 3046/70 Headings B1D and BIT [Also in Divisions B5 and H5] A filter element comprising a filter having an edge embedded in a support of thermoplastic or heat-hardened synthetic plastics material is produced by embedding the filter edge in a heated thermoplastic material or heat-hardenable synthetic plastics material which has been formed into a shape suitable for the support and which is in a soft or a liquid condition and then solidifying the plastic by cooling of thermoplastic or heating of heathardenable, wherein the heating is carried out by subjecting inductive particles suspended in the plastics material to a rapidly alternating magnetic field. The support material may be a fluxed vinyl resin (e.g. polyvinyl chloride) plastisol. The specified filter material is paper and the preparation of a cylindrical pleated paper filter element (Fig. 2, not shown) is described in which each end of the filter tube has been embedded in an annular plastics support member. Example 3 describes the preparation of a cylindrical oil filter having annular end caps, wherein the filter is formed of concentric tubes comprising a perforated metal cylinder within a pleated paper cylinder within a perforated paper cylinder and wherein the end caps are formed of resin impregnated paper formed by embedding the filter in the resin retained in an annular paper cap.
