Many a new feature gives the Hindenburg the right to the title of world's No. i dirigible. Prime aeronautical innovations are the first Diesel engines ever installed in an airship. Huge Daimler Benz V-8's made of a secret, lightweight alloy, they occupy four gondolas placed far back on the hull, leave a feathery wake of smoke as they shove the ship ahead at a maximum of 85 m.p.h. Only other projection through the smooth, silvery fabric of the Hindenburg's bag is the small control cabin near...
...believe that one-third as many ducks die from being poisoned as from being shot by bullets, Professors Robert Gladding Green and Ralph Dowdell of the University of Minnesota set out to save ducks by devising a healthy bullet. Last week they had perfected one. Their bullet: lead magnesium alloy, which dissolves less than 48 hours after it is eaten, before the lead causes anything worse than indigestion...
Molybdenum, first isolated in 1782, de rives its name from the Greek word meaning lead-like, is known in trade as "moly." Little use was found for the metal until the end of the 19th Century, when it was tried as an alloy for tool steels. Sulphur in the moly compounds then available un did what good the metal contributed, with the result that tungsten became the stand ard steel hardener. Not until the War, when it was employed in guns, motors, light armor plate, did moly impress steel makers...
...more linseed oil, turpentine and drier, and the paint is ready to apply. Add various tinting materials and the white paint assumes any desired color. National Lead aLso makes red lead, used most conspicuously as an anti-rust coating for structural steel. It has a line of lead alloys, particularly Babbitt metal (a lead-tin alloy used in bearings), type metal and solder. It is one of the largest U. S. tin users, with an interest in Simon Patino's Bolivian tin mines and in other tin producers. National Lead has not missed a preferred dividend since...
...vexatious problem is that of weight. Fuel tanks must be light but capable of withstanding high pressure. For the moment aluminum alloys serve fairly well for tanks and motor but not for the jet nozzles which often collapse in a few minutes. This is due not only to heat but also to the abrading effect of the issuing gases. "Will electrochemists supply us," asked Professor Klemin, "with another super-aluminum alloy to withstand all this...
