...than is now produced by the entire TVA system. Its miners already dig 90% of Brazil's iron ore, 95% of its bauxite, beryllium and mica, all of its graphite and nickel, most of its diamonds and gold. Its furnaces and factories lead the country in pig iron, steel and ferrous alloys, rank second in aluminum, cement and lime. And on its rolling farm lands, 16.5 million cattle and 8,500,000 hogs fatten for market. All this, though it is just beginning to wake up to the 20th century...
Right the First Time. The pioneers of nondestructive testing were the rail road brakemen, who used to tell if a steel car wheel was cracked by whacking it with a hammer to see if it rang true. United Air Lines technicians use basically the same principle today when they bombard jet turbine blades with electronically generated sound to see if the blades resonate at a frequency that indicates there is no danger of breakage. Westinghouse uses ultrasonics -super high-frequency sound waves - to probe right through big forgings in the rotors of its giant $2 million turbine generators and detect...
Dangerous Cracks. Republic Steel ensures that its seamless pipes are right before they leave the mill by using an electromagnetic testing machine that watches for breaks as the pipes rush by at assembly-line speed and determines whether they can be repaired. With such nonmagnetic metals as zirconium and tungsten, testers use penetrating oils to test products that are unresponsive to electromagnetic devices. Mixed with dyes that show up under ultraviolet light, the oils quickly reveal dangerous cracks in such important products as nuclear reactor components and power stations...
...French have their way, a ride on a subway need no longer be a nerve-racking, ear-wrecking experience on shrieking steel wheels. The government-owned Paris Metro, which celebrated its 63rd birthday last week, has just installed a revolutionary innovation on its high-traffic Vincennes-Neuilly line: cars that run along the tracks on pneumatic tires. The result of ten years of experiments commissioned by the Métro, the new system was developed jointly by tiremaker Michelin, automaker Renault and the Compagnie Electro-Mécanique. Eventually it will be used along the entire 160-mile length...
...rubber-tired, lightweight subway cars run on concrete or wide steel tracks and provide a swifter, far quieter and more cushioned ride for passengers. The friction of the tires allows quicker stops and starts so that trains can keep to faster schedules; on some runs the Métro figures that the extra speed will give it the capacity of five trains for the price of four. The trains are designed so that on existing subway systems they can share the right of way with older trains by straddling the steel rails on their own special track. But Transaco feels...
