MELTING OF IRON
EXTRAORDINARY CLAIM. (By Telegraph—Press Assn. —Copyright.) (Australian and N.Z. Cable Association.) LONDON, January 19. (Received January 20, 11.5 p.m.) Professor Desch, Dean of the faculty of metallurgy at the University of Sheffield, states that wireless valves can be used to melt masses of steel. Within a few months, large thermionic wireless valves will be installed in Sheffield furnaces. They will be specially useful in manufacture of nickel alloys. A two hundred volt direct current is passed into the valves which convert it into the alternating current of extremely high frequency. When the current passes through the metal, the latter becomes far hotter than the crucible containing it. A piece of iron is melted by the wireless valve before the cruicible becomes warm.
