...their profit on the cheap cooking oil that the poorest Moroccan families use. Ready to cheat, if not perhaps intending what happened, the merchants did not know that the American lubricating oil contained an anti-corrosive additive (tri-ortho cresyl phosphate), two grams of which, taken orally, are enough to cause paralysis of arms and legs...
...wanted to examine the racial situation in South Africa, but in doing so did not plan to meet any nonwhite leaders. In any event, his mind seemed already made up, for he told South Africans, "You're going ahead with solving your own problems, and that should be enough...
Through a Cone. After ten years of study, Avco scientists built a laboratory model MHD that produces 10 kw. of 55-volt electricity. This is hardly enough to run a gadget-filled kitchen, but ten big U.S. power companies have now joined with Avco to help develop MHD generators big enough to supply commercial power. A major advantage: an MHD generator has no primary moving parts, with the exception of those in the relatively simple compressor...
...They were easy to build because their double wings, braced by crisscrossed wire and struts, strengthened each other. But they were inefficient aerodynamically, and they had to be fooled with continually to keep their complex structure in proper order. The single wings of monoplanes were hard to make strong enough, but everyone knew that when they could be built, their efficiency and simplicity would make them dominant...
...goes well, the fuel burns evenly, acts as an insulator to protect the vulnerable metal casing from the searing heat of its flame. As the fuel is consumed, the cavity becomes nearly cylindrical, so when the flame reaches the outside wall not enough fuel is left to soften the metal. A well-made solid-fuel rocket engine can be touched with bare fingers just after firing on the test stand...
