...same principle underlies a technique, explained last week, for ferreting out defects in thick masses of steel. At the convention of the American Society for Testing Materials in Manhattan, Physicist E. V. Lange of Radium Chemical Co. demonstrated with a capsule containing one-tenth of a gram of radium. Gamma rays shooting out at a million or more volts passed through steel castings a foot thick, photographed the interior structure on X-ray films 10 by 12 in. in size. Tested by this method are steering posts of ships, turbines, valves, high-pressure steam pipes. Dr. Lange reported that...
...right hand froze to the metal cassette and table. He had neglected to turn off the supply of electricity, and 75,000 volts, 37 times as powerful as prison executioners use in electric chairs, poured through him. Electric chairs use five amperes of electricity, X-ray machines only one-tenth of an ampere, and although that small unit rushed through him like straws blown by a tornado, sturdy Frank Brown had strength enough to haul his stiffened left hand away from the X-ray tube to tug at his right hand frozen to the metal. The current gripped his right...
...Immingham Dock, Humber River, in the north of England, the little freighter Backworth last week loaded $10,000 worth of sugar, flour, fruit and dried salt fish for starving Basques in Spain's besieged Bilbao. More than one-tenth of the cargo was paid for by David Lloyd George who seldom misses a chance to make political capital of anything. Down to the dock hurried Britain's Wartime Prime Minister to wring Captain Russell of the Backworth by the hand...
This week on the eve of the new parliamentary session the furrows in Premier Blum's brow grew deeper. So apprehensive was the Paris Bourse that Bank of France stocks dropped 585 francs ($26), nearly one-tenth of their value. Meantime 30,000 small storekeepers assembled angrily in the capital to denounce Premier Blum's two-days-a-week closing order...
...likely to be thrown out of kilter by strong temblors originating nearby. Dr. Benioff has now devised what he calls an "earthquake resistant time- piece"- a clock driven by a 1,000-cycle tuning fork, which is in turn driven by a fourstage amplifier. This apparatus is accurate to one-tenth of a second per day and Dr. Benioff was sure last week that it would not be put out of whack by a quake unless the walls of the observatory themselves tumbled...
