Abstract

754,205. Moulding-processes and machines. POLYGRAM CASTING CO., Ltd. Nov. 5, 1953 [Aug. 8, 1952], No. 14874/55. Divided out of 754,112. Drawings to Specification. Class 83 (1). In a shell-moulding process, the moulding mixture is forced into contact with a heated pattern by movable ram, the contact being maintained for a time sufficient to allow a coating of'the desired thickness to be formed, and the ram being then withdrawn to allow the excess mixture to be removed. The subjectmatter of the Specification is contained within Specifications 754,111 and 754,112, which are referred to.
