...Fink's tungsten plate will be less ubiquitous. Its chief value lies in its resistance to hydrochloric acid. Only gold is so resistant. But gold is too precious to coat the pots and pipes of Industry. Professor Fink, 51, claims to be the "originator of the drawn tungsten filament'' for lamps.* Another scientist given the kudos is General Electric's Dr. William David Coolidge, 59. In 1914 the American Academy of Arts & Sciences gave Dr. Coolidge its prized Rumford Medal for the ''invention and applications of ductile tungsten." Dr. Coolidge also was in last...
...Tungsten lamps use 1.25 watts to produce one candlepower of light. Carbon filament lamps, which are still purchasable, give one candlepower for 3.25 watts. From these ratios statisticians figure that tungsten filaments save U. S. users of electricity one billion dollars yearly. Consumers buy 300,000,000 tungsten lamps a year...
...method; practice, not theory. No dilettante, he plunged into a project with sleeves rolled, working almost without rest for days and nights together until he made the lamp filament glow, until he made the phonograph talk. "Genius is nine-tenths perspiration," he believed...
Perseverance. To get a light-filament he carbonized thousands of materials? shreds from a fan, red hair from an assistant's beard. Thousands of invention ideas he tried, worked on, cast aside. He said that when an experiment seemed impossible of solution, that was the time to show interest, not discouragement. His was a standard phrase of the era: "Genius is 1% inspiration and 99% perspiration...
Professor Colin Garfield Fink of Columbia, who invented the drawn tungsten filament for electric light bulbs and developed the first commercial process of plating automobile hardware with chromium, last week announced that he was successfully electroplating objects with tungsten...
