Title: The Manufacture of the Hydrates of the Alkaline Earth Peroxides and their Application to Bleaching.
Inventor: JAUBERT GEORGE FRANCOIS
Filed: 1900-06-11
Granted: 1900-10-20
Abstract: 10,630. Jaubert, G. r. June 11. Barium, calcium and strontium hydrates.-The hydrates of the alkaline-earth dioxides, particularly that of calcium, are formed by double decomposition from their ordinary hydrates or from their soluble salts and the hydrate of sodium dioxide, or the materials from which the latter is made. For example, lime water, obtained from 56 kilogrammes of quicklime, is mixed with a solution of hydrate of sodium dioxide, corresponding to 78 kilogrammes of actual sodium dioxide in 1000 litres of cold water, and the mixture stirred. When the reaction is completed, the solution of caustic soda is filtered off, and the hydrate of calcium dioxide collected, washed, and dried. Or 74 kilogrammes of slaked lime in a fine powder are mixed with 78 kilogrammes of sodium dioxide, and the mixture submitted to the action of air both moist and freed from carbonic acid. When the reaction is completed, water is added, and the process finished as before. The products obtained are useful for oxidizing purposes, and especially for bleaching wool, feathers, and other materials.
Patent GB-190011304-A (GB)
Title: Improvements in Rolling Mill Appliances.
Inventor: MURPHY JAMES MICHAEL
Filed: 1900-06-22
Granted: 1900-07-28
Abstract: 11,304. Murphy, J. M. June 22. Rolling.-In a pack-rolling mill, the sheets are raised from the pass to the top of the rolls for returning to the front, and, at the desired time, are tilted or dropped into a box, by a pair of arms 4. The arms are loosely hooked to and pivoted on a bar 8, their rear ends being yoked to straps 16 on a long eccentric 14. The eccentric is carried by a shaft 15, which can be driven in either direction from a shaft 22 through clutches 24, 25. The clutch segments are normally pressed togther by springs 26, but are held out of engagement by spring pins 27, engaging cam-grooves in the segments and controlled by a foot-lever 35. By pressing down the lever, one of the clutches is engaged for five-eighths (say) of a revolution, and then disengaged. This effects the raising of the rolled plate to the top of the mill, and allows a second plate to be inserted while the first is being drawn over. On releasing the lever, the arms are brought down by the action of the reversing- clutch, which similarly effects five-eighths of a revolution and is then disengaged. During the downward movement, spring pins 18 passing through the straps engage a cam-groove 21 in the eccentric and open out the arms to clear the second plate as shown in dotted lines in Fig. 1. The arms have pivoted ends 5, which yield when pressed against the housing, but are returned by springs when the arms move inwards again. When the sheets have been sufficiently rolled, doubled, &c., a footlever 48 is operated to actuate a clutch 40 to lock the strap to the eccentric and rotate the shaft for a partial revolution. The arms are thus first unhooked from the bar 8, and then swung bodily over to tilt or drop the plates into a box 39. When the foot-lever is released, the various parts are returned. Rollers 36, driven by a chain 37, receive the plate issuing from the rolls.
