...just as the jester was in danger of having his head lopped off if his boldness should outrun his wit, so must the colyumist watch carefully lest he shock the Average Reader's sensibilities. Readers of Colyumist Harry Irving Phillips (''The Sun Dial") in the New York Sun one day last week wondered whether he had gone...
Efforts to perfect dial automatic switching began soon after Alexander Graham Bell invented the telephone in 1876. Some 3,000 patents for machine-switching devices have been filed in the U. S. alone. Out of all these patents, two main systems have evolved, the step-by-step and the panel.* The telephone subscriber cannot tell the two systems apart; the dials and the act of dialing look identical. But in the step-by-step system the mechanical combination necessary to ring the desired number is built up directly, by separate impulses from the dial. In the panel system, a more...
...step-by-step dialing system is based on Inventor Almon B. Strowger's patents of 1891. These patents were developed and exploited by Automatic Electric Inc., manufacturers of Strowger Automatic Dial Systems...
...direction finder or "homing device" invented by Radioman Geodfrey G. Kruesi of Western Air Express is supplementary to the ordinary aircraft radio. If the pilot cannot pick up the signals of the beacon, he simply tunes in on the known wavelength of any broadcasting station in the region. A dial on his instrument board then shows him his direction of flight in relation to the position of the broadcasting station. Last week Inventor Kruesi took his invention to Asheville, N. C, there to confer with his ailing department chief Herbert Hoover Jr. Later he was to show it to Army...
...instrument board. If the fuel mixture is too rich, the unburned gasoline vapor-hydrogen, carbon monoxide-will cause the platinum wires to glow hot (by its catalytic property), resist electricity. The battery current is thus shunted back through the nickel wires, to register on the graduated scale of the dial exactly what percentage of fuel is not being burned. Dr. Hutchison estimated the U. S. might save $1,000,000,000 worth of fuel per year (at a market price of 20? per gal.) by universal use of his invention...
