Abstract

356,245. Mould materials. DURAND, J., 142, Cours Lieutaud, Marseilles, France. June 2, 1930, No. 17050. Convention date, Nov. 9, 1929. [Class 83 (i).] In a process for making moulds for use in casting metals of the kind which comprises using a mixture of sand, a hydraulic binder such as cement and water, the proportion of the latter being between a lower limit below which the mixture is too friable and an upper limit above which the molten metal is liable to boiling, the inner surface of the mould is provided with a layer, which has already been used for the lining of other sand moulds, comprising talc, or barytes, or magnesia, or asbestos, or a substance rich in carbon such as coke or non-degasified coal.
