...matter where the experts may eventually fix the dose of radiation that can be considered safe, Commander Dobbins was sure that atomic sub crews-within a few yards of the reactor for 24 hours a day-so far have been exposed to only a fraction of permissible totals. When industry goes into full-scale production and operation of reactors for civilian power needs, it will have an invaluable body of data collected from the first men to go under the sea in atomic vessels...
...Driver Fangio, got so enthusiastic about Maserati racers in 1954 that he handed Adolfo Orsi a $3,000,000 machine-tool order to help speed Argentine industrialization. In turn, Adolfo enthusiastically allowed Peron three years to pay. A year later, when Peron was ousted, Argentina had paid only a fraction of its bill, all in wheat to the Italian government, which has yet to convert it into cash for Maserati. To top it off, Adolfo took on another $437,500 machine-tool order from the Spanish government-which has also failed to pay. Result: the Orsis owe subcontractors some...
...monkey deifiers. plus a dark fear that other countries really use the monkeys for rocket and radiation research. Whatever the reason, by last week the market was effectively killed. Unable to find enough six-pounders, hundreds of trappers went out of business in India, cut off all but a fraction of the monkey supply. And while U.S. drug houses have passed the peak of polio vaccine demand, the Indian ruling was a disaster to Britain, which is still forced to limit its small vaccine supply to children under...
SINS & SAC. The navigation problems were just as baffling. To aim any missile with accuracy, a missileer must know his own geographic position within a fraction of a mile. Land-based missile crews can set their guidance systems for the target on the basis of their known position. But how, traveling hundreds of feet below the sea, could the Navy subs fix position accurately? An error of a few hundred yards at launching point could mean a wide miss of the target 1,500 miles away. Advances in celestial navigation and radio astronomy systems helped, but the big answer came...
...traveling 23,000 ft. per sec. (15,600 m.p.h.), an error of I ft. per sec. in its top speed will make it miss its target by 500 yds. So when the desired speed has been reached, the thrust must be cut off accurately in a small fraction of a second. This is not too difficult with liquid-fuel rockets, whose thrust can be cut by shutting off the fuel. Solid-fuel rockets cannot be controlled in this simple way, but other effective ways have been developed. One of them is to blow off part of the nozzle...
