Abstract
1,192,102. Moulding diffuser assemblies. I. C. JENNINGS. 12 March, 1968 [13 March, 1967], No. 12040/68. Heading B5A. [Also in Division F1] A tubular casing 70 is lined with plastics material, comprising 20% epoxy resin filled with 80% steel particles, to form a jet pump diffuser (see Division F1), by pouring or injecting the plastics into a cavity defined between the casing 70 and a release agent-coated mandrel comprising separable parts 102 and 104, 106 respectively attached to end mould assemblies clamped against the casing 70 by tie rods 136. The upper end mould assembly is provided with openings 144 and 146 respectively for introducing plastics and venting. The mandrel is stripped from either end, after release of tie rods 136, by nuts 128, 130 which act on the casing 70 against the mould end assemblies. In alternative embodiments, Figs. 7 and 10 (not shown), the two-part mandrel is stripped by stripper bolts which act through the mould end assemblies on to flanges of the casing into holes whereof unthreaded end portions of the bolts locate to act also as aligning dowels, the separable parts of the mandrel being attached to, or comprising part of, the end assemblies which are clamped together by an extension of the lower mandrel part which extends through the upper mandrel part and is bolted thereto.
