...pump in any laboratory. Into one neck ran the usual filaments to conduct electric current. These filaments ended in electrodes, of which the negative one or cathode could be heated white hot electrically before introducing the main current. About this cathode was built another innovation in vacuum tubes, a metal cup designed to repel electrons backfiring against it and converge them forward in a narrow stream at greatly accelerated speed. This stream was pointed down the tube's other neck, a foot long, the sides of which were likewise sheathed in metal to guide the electrons on their...
When Dr. Coolidge ordered his 350,000-volt current turned on, a prodigious stream of electrons leapt from the hot cathode, moving perhaps two miles per second. Rebounding from the metal cup about the cathode, they raced off down the 12-inch exit passage of the tube until, when they reached the "window," they were going some 150,000 m.p.s. (four-fifths the speed of light). Their volume was virtually undiminished as they shot through the thin nickel foil and out into heavy, molecular air, where their effects were at once visible and startling...
Last week the price of tin on the London Metal Exchange was ?309 ($1497.11) a ton, the practical equivalent of the New York Metal Exchange's current quotation of nearly 70? a pound. These are slightly lower than the recent peak prices of more than ?318 ($1,540.71) at London and more than 71? at Manhattan. London gambling in tin has apparently ceased for a while, but London's control of this metal has not, for Great Britain holds suzerainty over the Federated Malay States (holders of 50% of the world's tin ore stores*) and controls...
...hard reality of deciding on the conspiracy or innocence of onetime (1921-24) U. S. Attorney General Harry Micajah Daugherty and onetime (1921-25) Alien Property Custodian Thomas Woodnutt Miller, who were charged with fraudulently allowing the transfer of $7,000,000 in stock in the American Metal Co. back to the original German owners. The defense lawyers had summed up their cases. Colonel William Rand, attorney for Colonel Miller, did it curtly. Max D. Steuer, in behalf of Mr. Daugherty, did it emotionally.* Prosecutor Emory Buckner in his final address announced that "we have the goods on Miller...
...White Bus. The White Motor Co. brought out a new six-cylinder bus last week with a 100-h.p. engine, overhead valves, 7-bearing crankshaft, 4-wheel metal-to-metal air brakes, 9-in. balloon tires, double-drop frame, 2-stage springs. The body, which is a single-decker, holds 18 to 23 passengers in the de luxe model for interurban service, 25 to 29 for less taxing city service...
