...known use for it; in 1923 its price was $5,000 per pound. But beryllium ores are scattered widely over the world and last week the price of the metal was down to about $11. Not quite twice as heavy as water, beryllium is one of the lightest of all metals. It is a third lighter than aluminum. Chemically wedded to copper or nickel, it makes an extremely hard, tough alloy. Nickel with only 2% of beryllium in it has a tensile strength of 260,000 pounds per square inch, as against 90,000 for stainless steel. Moreover, this nickel...
...General Electric researchers, who for years have studied lightning bolts striking Manhattan's Empire State Building, showed more interest last week in hydrogen-cooling for generators at the powerhouse. Since hydrogen is the lightest of all gases, it circulates with much less friction than air. As a result of cooling generators by hydrogen rather than air, the power output per pound of fuel is increased by 20%, and the fuel saving on a 200,000-kilowatt unit tots up to $20,000 a year. There is no fire or explosion hazard, because oil seals keep the hydrogen purity...
Developing 500 horsepower, the Ranger is the lightest powerplant of its size in the world (1.28 pounds per h.p.), weighs some 200 pounds less than European engines of the same design and power, has no counterpart in U. S. design. Jubilant Ranger engineers declared its principles were adaptable to bigger engines, refused to confirm a current report: that at its modest (100 employes) plant at Farmingdale, L. I., Ranger is already working on a new powerplant of more than 1,000 horsepower to compete with Allison...
...lightest element in Crime and the Man are the 24 charts which Dr. Hooton himself drew to illustrate his text. An amateur sketcher with a humorous line that many a cartoonist might envy, he calls his illustrations "nasty little human figures" (see opposite page...
...standard table of elements lists 92-from hydrogen, the lightest element, to uranium, the heaviest. An atom of hydrogen has one positive charge on the nucleus and one planetary electron; uranium has a positive nuclear charge of 92, and 92 attendant electrons. The existence of all these elements has been well established, except for Nos. 85 and 87 (alabamine and virginium),† whose discovery has been claimed by various investigators but not yet certainly confirmed. The existence of elements heavier than uranium is theoretically possible. In fact, such heavy elements of higher numbers than 92 are supposed to exist...
