Meanwhile steel-pipe makers have been whistling through their fingers. Steel is iron mixed with and hardened by carbon. Because it is easier to produce steel than to rid iron of its impurities, steel is cheaper than pure iron. It is also cheaper than-iron or steel alloys, and than copper alloys. But it oxidizes (rusts) many times faster than do those other materials...
Last week steel-pipe makers rejoiced when Clarence T. Coley, operating manager of Manhattan's old and lofty Equitable Building, and his Chief Engineer Carl W. Poulsen announced that they had discovered a simple way to clear rust from the steel plumbing of their building. They drain the water off and force dry steam into the pipes. The heat makes the pipes expand, the rust shrink loose from the pipes. The steam is released and water flushes the rust away. The pipes become clean, although pitted, and thinner than when bought...
...front cover} Should an ancient fire-worshipper, reincarnated, return to the contemporary U. S. scene, it is perhaps in a steel-mill that he would find his most congenial employment. For the heart of the steel-mill is the flame of its furnace, and the power of the steel-mill is the heat of that flame. Cold and solid is steel to the layman. Hot and liquid it is to the steelworker, who is essentially one of dozens of cooks attending a titan's kettle of boiling muck. To him, it seems, the fiery mess is continually boiling...
...James Cunningham of Kansas City, Mo. (with theory), who have built at Cleveland a great spherical tank to treat various diseases by means of compressed gases (TIME, June 4, 1927), to learn last week that the Harvard Medical School will experiment on the same lines. Harvard is installing a steel pressure cylinder 35 ft. long, 8 ft. in diameter, in which investigators can change air pressure from 60 Ibs. per sq. in. to the legerity at the top of Mt. Everest (5 mi. high). Primary studies will be on heart disease, pneumonia, bends...
...dull red coat of preservative paint is the usual lot of structural steel, a dull red which is promptly censored by an overcoating of black. But from now on, the structural steel for all skyscrapers whose frames are by the Hay Foundry & Iron Works of New York will shine yellow in the glare of the sun. The first of them will be the Louis Adler Building, now arising on Seventh Avenue at 37th St., Manhattan...
