Abstract

1397822 Casting moulds AKITA KK 18 April 1972 [27 April 1971 (2) 25 June 1971] 48928/74 Divided out of 1397821 Heading B3F Apparatus for casting molten metal comprises a mould form 4, 8, and a mask 6, 10 complementary to the surface of the form, the mask being supported by compacted heat-resistant particulate materials in a chamber partly defined by the mask and means for reducing pressure in the chamber to hold the mask against the particulate materials. The apparatus is as described in Specification 1,397,821.
