Aluminum Crane. Six unusual overhead traveling a w e s have recently been huilt by the NorthEngineering Works, Detroit, Mich., for the U. S. Aluminum Co. for he unusual feature of these cranes use in its new sheet rolling & I s a t ~ l c o a Tenn. , is that each entire unit is made from aluminum alloy rolled structural sections and aluminum alloy castings. The mane illustrated has a capacity of 10 tons, the bridge space is 76 ft. 6 in. between truck wheels, and the hoisting hook has a height l i t of 25 ft. The hoist operates a t a full load speed of 50 ft. per minute, the bridge 400 ft. per minute. and the trolley 150 ft. per minute. The total net weight of the crane is 30,000 pounds, compared t o 77,100 pounds for the sad; size equipment if built of steel.-News Ed., Ind. Eng. Chem.,8,16 (Oct. 10, 1930)
Unique O&e of Nirosta Steel. An office, decorated and fitted throughout in the same metal that gleams from the tower of the lofty Chrysler Building, has been added t o New Ymk's list of novelties. This ofice. located on the twenty-sixth floor of the New York Central Building, is creating something of a sensation among those interested in the possibilities of the new alloy. I n a display room h a n exhibit of products produced from Nirosta steel ranging from a coil of wire having a diameter of less than half that of a human hair, t o a huge chemical tank capable of handling boiling adds without material deterioration. The room itself is paneled with Nirosta sheets that have been mound t o a satin finish around the borders with a raised polished center. The deeo&ive design has been etched into the metal and the furniture and exhibits inelude examples of this alloy in cast, rolled, d r a m , spun, welded, wire, etched, and riveted form. The product today has found its way into leading industries. A large tonnage has been used in the oil industry. %me of the other industries using it which are represented in the exhibits are the automotive, chemical, paper, architectural, food, marine, and aviation. There are 48 American steel manufacturers of prominence now licensed t o produce this material. The office and display room is maintained for these licensees by the Kmpp Nirosta Co., 1nc.-News Ed.,I d . Eng. Chem.,8, 12 (Sept. 10, 1930)
