...down below Japan's fleets of bombers, American surgeons, supported by countless church missionary suppers, labor night and day removing the shrapnel which crashes into Chinese flesh almost directly from our own scrap-iron heaps. Their medical supplies diminish as Japan announces that these materials will no longer be admitted...
Small compared to the quantitative increase in U. S. productive capacity in 1920-29, the Five-Year Plans represented a greater rate of increase. They doubled Russia's industrial stature, made her an industrial power, left her self-sufficient in production of oil, coal, iron ore, manganese, cellulose, cotton, super phosphates. But it set a vast segment of the Russian proletariat moving from factory to factory, from village to city, in one of the great tidal movements of humanity that Tolstoy long ago described as the ceaseless wanderings of workmen over the earth. It ended uniform wages. Breakdowns, delays...
...about 1870 railroad rails were made of iron because the cost of making steel in quantity was prohibitive. Then the converters invented by Henry Bessemer got going and steel became much cheaper. In Bessemer converters-little changed after 70 years-a powerful blast of air is forced through molten pig iron as it lies in the converter's capacious belly. The air oxidizes impurities which form a slag or pass off as gases through the converter mouth. After the slag has formed, the steel is poured into molds to make ingots...
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...
...Manhattan, Housewife Anna Abdou invaded a classroom in Public School 78, an ax in one hand, two iron stove legs in the other, screamed: "I hate kids. I'm going to kill you all." While the teacher tried to calm her, then tried to ignore her, Mrs. Abdou smashed doors, desks, radiators. Arrested, she explained that the school children persistently threw stones through her windows...
