...rules. There a network of dark lines traces 21,764 mi. of airway. Scattered white pins mark the nation's 2,034 airports. Lighted emergency landing fields stand out as 382 green pins while 53 blue pins designate radio beacons, 1,567 red pins, rotating beacon lights, 386 nickel pins, acetylene blinkers...
Since any mechanical vibration is sharply resonant, and better than the best electric circuits which can be built Professor Pierce has also been at work on magnetostriction rods, usually an alloy of nickel and steel, used, experimentally, as a source of air waves, similar to sound waves, but above audible limit, especially in the range: 30,000 to 50,000 cycles. Such waves can be focused, confined to narrow beams like those from a searchlight. Both the quartz crystal and magnetostriction rod are being worked on for communication purposes, and are also used to study the elastic properties of materials...
...pushes the whole scheme within ten minutes of an electrocution. Mr. Corotto took all this trouble because he found out that his sulky mistress (Marguerite Churchill) was the boy's best girl. It is the mistress who finally punctures the plot and Mr. Corotto, too, with a nickel-plated revolver...
...often so large that they are not oxidized by the time they penetrate the earth's layer of atmosphere. The meteorite discovered by Admiral Peary on his North Pole Expedition in 1909 is of the metallic type, composed of 95 per cent iron and a small amount of nickel. The Tent. as it is called because of its peculiar shape, weighs over 36 tons. A celestial visitor almost twice as large has been dug out of a hole in South Africa. Although expeditions have been trying to discover some fragments of the object that caused the huge pit known...
...Copper-nickel alloys, said Dr. Paul Dyer Merica of International Nickel Co., are now prepared by heat treatment to stand a pull of 175,000 Ib. per sq. in., a tensile trength comparable to that of heat-treated steel...
