Westinghouse has solved a delicate problem in electronic tube-making. A steel splinter used to be thrust into each tiny coiled filament for support while it was welded. But removing the steel support afterward was difficult. Now a slender stick of raw spaghetti, turned out to a thousandth-of-an-inch accuracy, takes the steel's place. After the coil is welded, an electric current burns up the spaghetti core in a flash. For this ingenious idea, which cuts filament-assembly time from five minutes to one, Westinghouse Engineer William A. Hayes got a WPB award of Individual Production...
...this in itself seems like a perfectly natural query which bars no distinctive quality to make it worthy of being identified as a milestone. Yet milestone it is! For it was from the lips of this anonymous interrogator that came forth for the ten-thousandth time the phrase which this yeoman has listened to, answered and lived with these many moons...
Goodyear's new "radio static neutralizer" has a set of electronic tubes that intercepts outside electrical interference and reduces it to less than one twenty-thousandth of a volt. In one test a 25,000-volt spark projected on a radio antenna was so effectively tamed by the neutralizer that the set smoothly brought in a short-wave broadcast from Europe. But the neutralizer is reserved for the armed forces, will not be available to civilians until after...
Radium's third best market is the luminous paint industry, which is booming. A very little radium goes a long way: combined with zinc sulfide, one-thousandth of one gram (there are 28.35 grams in an ounce) can illumine thousands of needles on thousands of aircraft dials...
...uncanny accuracy of quartz crystals in frequency control demands unyielding accuracy in manufacture. The wafers must be cut with due attention to the structure of the mother crystal, must be ground to within a ten-thousandth of an inch...
