...enough lead, zinc, and magnesium. That was all. Two-thirds of her iron ore and 85% of her copper had to be imported. To feed her highly-developed smelters at Leipzig, Breslau, etc., she had little or no bauxite (aluminum ore), antimony, tin or the critical ferro-alloy metals: molybdenum, tungsten, chrome, nickel. The map shows how conquest enlarged her resources. Fine lines show her post-Versailles boundaries, the heavy line her holdings at the end of year I of World...
...them, frail M. I. T. man John Henry Walthall, had developed a new process for extracting alumina (raw material of aluminum) from common clay, which abounds in TVAland. Other TVA discoveries include methods for making a cork insulation substitute out of vermiculite (a mica-like rock), for deriving magnesium from olivine, plastics from cottonseed hulls...
...reflector has made it necessary to include several unusual features. Construction is being super-intended by Mr. Herbert E. Hanson of the observatory staff. Except for the polar axis and counterweights, the mounting is of Dowmetal,--probably the first telescope mounting ever made of this specially light and strong magnesium alloy. The Dow Chemical Company, of Midland, Mich., cooperated in providing the difficult castings necessary for both the telescope tube and mounting...
...Talking carelessly to reporters, Arnold produced huge headlines, vague stories about defense-hindering control of U. S. patent users by the German firm of Krupp. He had designs on a number of industries in which foreign patent tie-ups were said to be restricting U. S. production, among them magnesium, whose chief producer, Dow Chemical Co., has built an independent U. S. magnesium industry (using sea water as ore) from its own smart research. Arnold also got off a phrase about "economic fifth columnists" which he later tried to define, finally retracted. The vagueness of his charges, coupled with...
