inside, sodium chloride packed round, 20 tons pressure, 8 k.w.m. totab 



heating. 

 2-inch mould ; aluminium coil core, wood charcoal round, phosphorus at 



base, 6 tons pressure, 3 k.w.m. total heating, heating 1 minutes. 

 4-inch mould ; 1-inch aluminium rod core, drilled centre f-inch filled 



with carborundum charcoal around, 20 tons pressure, 50 k.w.m. total 



heating, heating 1 minute. 

 2-inch mould ; carbon rod core, phosphorus and carborundum round, 



graphite on top, 20 tons pressure, 8 k.w.m. total heating, heating 



14 seconds. 

 4-inch mould ; magnesium and silicon carbide core, magnesia round, 



graphite top and bottom, 20 tons pressure, 57 k.w.m. total heating, 



heating 2 minutes. 

 4-inch mould ; 1-inch carbon core, boric anhydride round, 20 tons 



pressure, 22 k.w.m. total heating, heating 5J minutes. 

 9-inch mould; 2-inch carbon core surrounded by wood charcoal, poles 



water jacketed, 10 tons pressure, 400 k.w.m. total heating, heat melted 



lower pole and made hole into water cavity causing explosion, molten 



iron shot out on to floor and walls, heating 4^ minutes. 

 4-inch mould ; 1-inch carbon rod core, drilled f-inch hole, filled with 



calcium carbide, sand top and bottom, 30 tons pressure, 50 k.w.m. 



total heating, heating 20 minutes. 

 4-inch mould; |-inch carbon core, sand, carbon silicide, and calcium 



carbide in layers round it, 30 tons pressure, 40 k.w.m. total heating, 



heating 8 minutes. 



Same arrangement of mould, but calcium carbide and carbon silicide 

 only, plus small amount of sulphur, :!0 tons pressure, 7 k.w.m. total 

 heating, some iron present from bottom poles, and also CO produced, 

 heating 1 minute. 



4-inch mould ; J-inch carbon core, sand top and bottom, |-inch layer of 

 calcium sulphide in middle, 28 tons pressure, 30 k.w.m. total heating, 

 some iron present from bottom pole, also CO produced, heating 

 20 seconds. 



Same, but layer of calcium carbide, sulphur added to sand 



4-inch mould; '-inch carbon rod core, sand top and bottom, calcium 

 oxide in centre, plus 5 per cent, ferric oxide, 30 tons pressure, 

 47 k.w.m. total heating, heating 15 minutes.

 sand in middle, 30 tons pressure, 14 k.w.m. total heating, heat of 10 

 to 20 kilowatts applied for 30 seconds, four times, with 30 seconds 

 intervals. 



4-inch mould; slaked lime top and bottom, sand, salt (10 per cent.) 

 in middle, 30 tons pressure, 8 k.w.m. total heating, heating 

 35 seconds.
