Abstract
754,112. Moulding-machines. POLYGRAM CASTING CO., Ltd. Nov. 5, 1953 [Aug. 8, 1952; Jan. 2, 1953], Nos. 20082/52 and 202/53. Drawings to Specification. Class 83 (1). A shell-moulding process consists in passing each of a series of patterns in turn through a heating zone, applying a lubricating or stripping agent to each pattern prior to investing each pattern in turn with a shell of moulding- mixture by moving a sufficient mass of moulding mixture into contact with each pattern in turn, removing surplus mix, passing the invested pattern through the heating zone to cure the shell, and removing the cured shell after it has emerged from the heating zone; the cycle being continued as before by 'investment of the pattern, from which the cured shell has been removed, with another layer of mix, preceded either on each occasion or periodically by the application of stripper to the pattern. The Specification is substantially identical with that of Specification 754,111, which is referred but also refers to the application of mix to the pattern by pressure only, the mix container not being inverted in this case. Specification 754;205 also is referred to. Reference has been directed by the Comptroller to Specification 674,421.
