Seite i - WAGNER, Ph. D., Professor of Chemical Technology at the University of Wurtzburg. Translated and edited, from the eighth German edition, with extensive Additions. By WM. CROOKES, FRS With 336 Illustrations. I vol., 8vo. 761 pages. Cloth, $5.00. The several editions of Professor Rudolf Wagner's " Handbuch der Chemischen Technologic" have succeeded each other so rapidly, that no apology is needed in offering a translation to the public.
Seite iii - Technologic" have succeeded each other so rapidly, that no apology is needed in offering a translation to the public. Under the head of Metallurgic Chemistry, the latest methods of preparing Iron, Cobalt, Nickel, Copper, Copper Salts, Lead and Tin and their Salts, Bismuth, Zinc, Zinc Salts, Cadmium, Antimony, Arsenic, Mercury, Platinum, Silver, Gold, Manganates, Aluminum, and Magnesium, are described. The various applications of the Voltaic Current to Electro-Metallurgy follow under this division....
Seite iii - Aluminum and Magnesium, are described. The various applications of the Voltaic Current to Electro-Metallurgy follow under this division. The Preparation of Potash and Soda Salts, the Manufacture of Sulphuric Acid, and the Recovery of Sulphur from Soda-waste, of course occupy prominent places in the consideration of chemical manufactures.
Seite iv - Preservation of Meat, Milk, etc., the Preparation of Phosphorus and Animal Charcoal, are considered as belonging to the Technology of Animal Products. The preparation of...
Seite iii - Stone-ware, Limes, and Mortars, will present much of interest to the Builder and Engineer. The Technology of Vegetable Fibres has been considered to include the preparation of Flax, Hemp, Cotton, as well as Paper-making ; while the applications of Vegetable Products will be found to include Sugar-boiling...
Seite 485 - The solutions of caoutchouc in coal tar, naphtha and benzoline are most suited to unite pieces of caoutchouc, but the odor of the solvents is perceptible for a long time. As chloroform is too expensive for common use, sulphide of carbon is the most usual, and also the best, solvent for caoutchouc. This solution, owing to the volatility...
Seite 680 - ... of the most splendid description. When an electric lamp, furnished with rods of gas-carbon half an inch square, was placed at the top of a lofty building, the light evolved from it was sufficient to cast the shadows from the flames of the street lamps a quarter of a mile distant upon the neighbouring walls. When viewed from that distance, the rays proceeding from the reflector have all the rich effulgence of sunshine.
Seite iii - Waste, of course occupy prominent places in the consideration of chemical manufactures. It is difficult to over-estimate the mercantile value of Mond's process, as well as the many new and important applications of Bisulphide of Carbon. The manufacture of Soap will be found to include much detail. The Technology of Glass, Stoneware, Limes and Mortars, will present much of interest to the Builder and Engineer. The Technology of Vegetable Fibres...
