Abstract

872,641. Moulding processes. SULZER FRERES S.A. Aug. 8, 1958 [Aug. 15, 1957], No. 25562/58. Drawings to Specification. Class 83 (1). Destructable patterns are removed by solvents with the aid of sonic vibrations. The pattern may be of common salt or of urea with up to 10% of polyvinyl alcohol, or an amount of combustible fibres, and the solvent water, or of wax and the solvent trichloroethylene, or of polyethylene glycol. Specifications 722,884, 872,640, 872,642 and 872,643 are referred to.
