Since 1920 steelmaking has had a big swing to the open-hearth process. These furnaces, lined with dolomite (lime and magnesia oxide), are primed with plate scrap and limestone, then charged with pig iron, scrap and ore, and heated. Gas expelled from the limestone stirs the mixture, helps form the slag. A furnaceman spoons out samples, cools them to test quality, then adjusts the heat to get just the quality he wants. After about twelve hours the furnace is tapped, the steel ladled off. The Bessemer process is three times faster than the open-hearth, and correspondingly cheaper; but since...
...have fared thinly in recent years, had developed a photoelectric indicator ("robot eye") which, by judging the color and brilliance of a Bessemer heat better than human eyes can, made it possible to turn out steel with Bessemer rapidity but of a uniform quality comparable to that of the open-hearth product. The J. & L. researchers guarded their secret vigilantly, declared darkly not long ago that two other companies had tried to swipe...

Meanwhile San Francisco sat and moped over its music. Director of the San Francisco Fair's music, dollar-eyed, dewlapped Harris De Haven Connick, had pictured a rosy future on an $800,000 budget.

...puppet state in Spain, how he had shot his generals on framed evidence furnished by the German Gestapo, how his every political move was directed toward making a deal with Hitler. Although a few informed critics questioned some of General Krivitsky's facts and many open-minded persons questioned his disinterest, no one questioned his identity until last fortnight, when the editors of the Communist New Masses popped out from behind the curtains and. leveling accusing fingers at the general, declared...
