Abstract

1421938 Cupping GOLDEN VALE FOOD PRODUCTS Ltd 6 June 1973 [7 June 1972] 27054/73 Heading B3Q Dished ends 11, Fig. 6, e.g. for storage vessels, are made by securing a metal disc, Fig. 5 (not shown), over a flat end 2a of a rigid support 1 and deforming the disc by fluid under pressure delivered to the flat end. The support 1 may consist of opposed cup-shaped members 2, Fig. 1, welded to a ring 3 and reinforced by radial spokes, Fig. 3 (not shown). A water inlet 6 has branches to each end face 2a, and the support is filled with concrete. A stainless-steel disc 11 may be mounted over each end 2a by welding their rims together at 14 and locally to the inlet at 15. After inflation of the discs the welds are broken. The support 1 may be made of cast iron.
