Abstract
428,615. Casting permanent magnets. LUCAS, Ltd., J., and WATSON, E. A., Great King Street, Birmingham. Nov. 16, 1933, No. 31946. [Class 83 (i)] Moulds.-A mould for use in the casting of permanent magnets has a casting chamber of a metal of good thermal conductivity surrounded by a relatively massive metal body having a high latent heat of fusion and a melting temperature of about that at which the heat treatment of the casting is to be effected. The casting-chamber a of copper is supported concentrically within an iron shell b by a number of radial copper ribs c, the spaces between the ribs being filled with aluminium d which has a high latent heat of fusion and serves therefore first to cool the casting then maintain its temperature prior to the final cooling.
