After trying 224 chemicals, Dr. Frank Earl Denny discovered that potatoes treated with ethylene chlorohydrin vapor flung up 2-ft. vines and began to bear before untreated potatoes showed above ground. Now Southern potato growers using this medication on hardy plants from the North can collect two crops a year...
...experiments and reports for the Electrochemical Society convened in New Orleans. For nearly a century there has been controversy over whether carbon was liquefied in the heat of the arc. The Cleveland chemists showed conclusively that the carbon does not liquefy but sublimes directly from a solid to a vapor as dry ice does. The sublimation point is a fundamental constant of the element and represents the maximum arc temperature. Determining this constant within narrow limits provides, according to Dr. Chaney, "a convenient and much needed bench mark for all high temperature measurements." It is of help especially to makers...
...first thoroughly cleaned with blasts of electrons. It is then placed in a big sealed tank from which pumps suck almost all the air. Within the tank is a coil of tungsten wire covered with aluminum. When the wire is electrically heated the aluminum boils off as a vapor which, when it strikes the mirror's cool surface, condenses in a thin, even film...
...glass sphere with tubular extensions on opposite sides, the Ignitron is an ordinary mercury vapor lamp except that the electrodes are the pool of mercury in the bottom of the sphere and a graphite pole above it. When struck by the bullet, the copper wire closes a switch which passes electric current to the mercury. A spark then leaps between pool and pole. The flash lasts...
...idle toy, the Westinghouse device serves industry as a delicate circuit breaker for aluminum welding, as a mercury vapor lamp for producing stroboscopic light by which to inspect revolving parts. A very fast series of flashes illuminates the part at the same point of every revolution, and thus, because of persistence of vision in the human eye, the part appears to be standing still. Massachusetts Institute of Technology researchers have used mercury vapor stroboscopes in connection with a super-fast camera to record the impact of a golf club with the ball, the splash of a drop of milk...
