Abstract

890,054. Casting-processes. DE HAVILLAND ENGINE CO. Ltd. July 5, 1960 [July 6, 1959], No. 23178/59. Drawings to Specification. Class 83 (1). Castings are kept from contact with oxygen during the period between solidification and cooling to about 500‹ C. less than the temperature of solidification. The casting and cooling may take place in an inert atmosphere, or in a vacuum.
