Dream Walking. In Portland, Ore., a sober policeman put his hand in a drunk's pocket, drew out a snake...
Hunters. In Wheeler, Ore., an excited hunter stumbled, fell when a flock of geese honked overhead. His gun went off, bagged three. In Pittsfield, Mass., a hunter fired his shotgun at a squirrel in a tree, missed, brought down four raccoons...
...task of welding these two masses -the untrained ore and partly trained ingots-into a more or less efficient machine was entrusted three weeks ago to a good general, Klimenti Voroshilov, and a not-so-good one, Semion Budenny. Last week Marshal Voroshilov reached Russia's auxiliary capital at Samara to organize his great new Army. And as he traveled east to the rear, he passed trainload after planeload of special winter troops, trained since the Finnish war in cold-weather war fare. There were said to be 750,000 of them, of which some 200,000 were reported...
This is at least as simple as the present method of making alumina from bauxite ore, which is by no means pure when mined. Its gross impurities, such as sand, are removed by crushing, washing, sifting. It is then dissolved in hot caustic soda or "lye," which does not dissolve the subtler impurities. When the hot lye cools in towering tanks, pure aluminum hydroxide separates from it and is ready to be baked and electrolyzed...
...been pioneering the extraction of magnesium from water, others have been studying how to extract magnesium from rock. TVA scientists are working on the Carolinas' abundant magnesium silicate called olivine, of which 27% is recoverable magnesium (in contrast to sea water's .1%). When this ore is mixed with hydrochloric acid, magnesium chloride is formed which can be treated by electrolysis just like that from water. Because olivine is so rich in metal and TVA power sells cheaply, experiments have been launched at Georgia Tech in the hope of making this a major U.S. source of cheap magnesium...
