Convention date, March 9, 1929. Void [Published under Sect. 91 of the Acts]. [Class 83 (i).] In casting motor-car cylinder-blocks &c. the metallic cores or inserts in the mould are coated with one or more substances having a low heat conductivity to prevent too rapid chilling. Graphite or pipe earth mixed with 10 per cent of glucose, dextrine, or sugar and sufficient water to make a paint is found suitable. If desired some of the dextrine may be replaced by linseed oil.
