Electroplating stout metals with aluminum was described at the Chicago Institute of the American Chemical Society last week. If the process should become practicable commercially, housewifery and industry will benefit by inestimable billions. Pots, pans, vats, machines exposed to corrosives will be protected by a skin of aluminum, metal highly resistant to mos.t acids and alkalies...
Other chemists as learned as Professor Keyes, however, doubt the practicability of his electroplating with aluminum. He takes an aluminum salt (like aluminium bromide), dissolves it in an organic solution (ordinary electroplating uses metal salts in water), submerges the object to be coated, and through both solution and object passes a direct electric current. The procedure is very difficult to carry through, is expensive-and so probably not generally useful. Aluminum Co. of America is not using...
...Aluminum Co. of America using three other suggested methods of shielding base metals against corrosives with aluminum. One of these is mightily to press thin sheets of aluminum against sheets of steel. Workability here is limited. Germans are using this process in a semi-commercial way. Another is to heat iron and steel in contact with aluminum. This calorizing process (exploited by Calorizing Co. of America at Pittsburgh, a General Electric offshoot) helps prevent oxidation, but reputedly little else. Lastly there is spraying objects-of wood, paper, metal, etc.-with aluminum particles. An aluminum wire is fed through an electric...
...latest difficulty has been with aluminum furniture. Furniture makers, materially conservative, refused to listen to Aluminum Co. technicians. Sheet metal fabricators might be shouting success about their metal office and home furniture. But the public really wanted wood, declared the furniture men. So Aluminum Co. simply went into furniture manufacture. First products to be exploited are office chairs-"easy chair comfort when you need it most." The material (upholstered) is as stout as mild steel and much lighter. The chairs, and other furniture already on sale, are coated in the exact grain of wood-mahogany, walnut, oak. When professional furniture...
...started at 10 p. m., as I had determined to use the moon and climb all night. . . . We dispensed with a lantern, Hans helping me admirably, with knee and shoulder, and guiding my metal peg to its foothold with the precision of a chess player moving a pawn. We . . . arrived upon the summit at 7:30 a. m. . . . Then came the long terrors of the grim descent-always worse than the ascent for the legless man ... it was over at last...
