...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...

...provided with a small slit through which a beam of light passes at each swing of the pendulum. The beam of light falls on a photoelectric cell and produces an electric current of short duration each second. These current pulses drive an auxiliary second's counter and clock dial for registering the time and also give magnetically impulses to the master pendulum for maintaining its vibration. This clock is timed once a day by radio signals from Washington which registers on a moving tape along with the clock ticks in such a way that the timing can be done...
