Page 8 - The committee recommends drawing the line between cast iron and steel at 2.20 per cent. carbon for the reason that this appears from the results of Carpenter and Keeling to be the critical percentage of carbon corresponding to the point "a" in the diagrams of Roberts- Austen and Roozeboom.

Page 134 - ... temperature of the gases which go to the stack. The amount of space actually occupied by the bricks, or checkerwork, is the important consideration, however, and this should be from 5000 to 10,000 cubic feet for all four regenerators in a 50ton furnace. The capacity of the two gas regenerators is usually less than that of the air regenerators, because the volume of gas used is less than that of the air, and also because the gas does not require to be preheated so much, since it is already somewhat...

Page 9 - Steel. — Iron which is malleable at least in some one range of temperature and, in addition, is either (a) cast into an initially malleable mass; or, (b) is capable of hardening greatly by sudden cooling; or, (c) is both so cast and so capable of hardening.
