...ordinary incandescent bulb. Filled with oxygen, the bulb contains a specially coated filament and crumpled sheets of thin aluminum foil. When the circuit is closed the filament lights, ignites the aluminum foil. Each bulb is used only once. The lamp can be plugged in on an ordinary 115-volt alternating current circuit, or can be used with batteries. The flash lasts only 1/100 sec. Being completely self-contained, offering no fire hazard, the flashlamp can be used where flashlight photographs have never been taken before, in trains, aircraft, rainstorms, under water...
...charge of an electron to its mass. This research makes use of a direct measurement of the time required for an electron to move from one point to another under the action of a high-voltage field. The electric field was obtained by the use of the 100,000-volt storage battery belonging to the laboratory and the timing of the electron was accomplished by a short wave oscillator. The frequency of the oscillator was obtained by the use of piezo-electric standards of frequency which were also developed in the laboratory and have come into great importance commercially...
...half later, groping blindly through the pea-soup atmosphere over Jersey City, narrowly missing rooftops. Pilot John Salway saw a chance to land in a meadow, saw too late the wires that marked it as the county's 200-acre power plant. A wingtip sheared a 132,000-volt wire. A flash, a crash, a geyser of flaming gasoline ended the episode...
...stepped into a tobacco store to buy and light a cigar. The store's owner had ignorantly connected a small 6-volt electric cigar-lighter to a high-powered city current. Schall put his face down to the lighter, gave it a flick. A terrific flash followed which permanently blinded both his eyes. With his wife's assistance he continued his law practise. She read him the cases; he argued them in court. In 1914 the backwash of the 1912 Bull Moose movement carried him to the House of Representatives as a Progressive...
...close the arc he squeezed harder. The harder he squeezed, the more current leaked into his arm, made it jerk crazily. Had he not been standing on a cork-insulated floor, had he not kept clear of a well-grounded duct a few inches from his foot, the 220-volt current would have killed...
