Colored television has become possible because Dr. Ives's colleagues at Bell Telephone laboratories invented a photo-electric cell more sensitive to light than the usual cell. The usual cell depends on the ionic action of potassium and hydrogen. The new cell uses sodium with sulphur vapor and oxygen...
...using the latter for propulsion of the former as has been done experimentally at the Opel works in Germany. The core of his cogitations concerned the materials to be fused to attain speed in and out of Earth's atmosphere. He described two kinds of fuses-one using hydrogen, the other of alcohol-which he calculated would drive a plane 13,120 ft. per sec., or about 9,000 m. p. h., making the 240,000-mile trip in some 27 hours...
...charge up into the big silvery bag. He accompanied his shot with dancing, gesticulations and lilliputian shouts. The lead pellets, though buckshot, tore only small holes in the ship's fabric. But they might have struck machinery, caused disaster. Had the Los Angeles been inflated with inflammable hydrogen instead of inert helium, she might have blown up. And anyway, it is not proper to shoot at the U. S. Navy's one and only big dirigible. Carpenter Merton Hankins, the lilliputian gunner, was arrested. Last week he was tried for assault with attempt to kill...
...standard method of reducing a gas first to a liquid, then to a solid, is to force it through a fine nozzle, thus causing it to expand and cool. Successive passages through the nozzle make the gas increasingly cold, requiring greater and greater pressure to force it through. Liquid hydrogen is used to absorb the heat from cooling helium. Professor Onnes found that helium would not liquefy until reduced to just below five degrees above Absolute Zero. He got the temperature down three more degrees, but could not solidify the helium fluid...
...official of Helium Co., which prepares that gas for use in dirigibles, announced last week the discovery of a new helium deposit, the situation of which was not made public. Helium, which is almost as light as hydrogen, has the great advantage of being non-inflammable. But, rare, it is expensive (about $35 per 1,000 cu. ft.). It is found mixed with natural gas. Hitherto there have been but two chief U. S. helium sources: 1) the Federal well at Amarillo, Tex.,? which yields 1.75% of helium; 2) Helium Co.'s well at Dexter, Kan., which yields...
