1,175,690. Casting end walls on articles. E.I. DU PONT DE NEMOURS & CO. 13 Dec., 1966 [22 Dec., 1965], No. 23141/69. Divided out of 1,175,687. Heading B5A. The end walls of the fluid separation unit described in parent Specification 1,175,687 formed by using a centrifugal casting apparatus. The casing 101, Fig. 12, of the fluid separation unit carries end moulds 905a, 905b and a settable material, e.g. an epoxy resin, is fed to the mould inlets 908a, 908b from a feed assembly 917 to the grooves 918 of which casting liquid is supplied from containers 920. The mould support is rotated by a motor 913 through a belt and pulley transmission. The moulds are removed and the resin cut across the line CL, Fig. 10, to open the ends of filaments 112 of the fluid separator. To obviate the need for this cutting, a liquid, e.g. a fluorocarbon oil, which is immiscible with the resin and is more dense, is supplied to the mould cavity so that on removal of the moulds only the ends of the filaments have to be cut open, Fig. 11. The centrifugal casting apparatus may comprise a plurality of pivotally mounted casings 101, Fig. 13, carried by a support and swingable to a horizontal position on rotation of the support. The moulds 905a, 905b being supplied with solidifiable liquid as before. |
