    摘要： A novel solution obtained from a process for treating dyehouse waste water, containing leftover dyestuff, for reclamation and reuse for consecutive dyeing and/or rinsing or the like, in which halogen, such as gaseous chlorine, is added to decolorize the chromophoric functional group of the dyestuff. The decolorized waste water is then recycled into the dyeing system to form the present solution.

    摘要： An extraction process for recovery of phosphorus compounds from both low and high grade phosphate ores utilizes a room temperature extraction with dilute mineral acids whose calcium salts are water soluble. Preferably the ore is coarsely ground. Dissolved impurities are removed from the dilute phosphate solution by a first neutralization step, whereafter further neutralization precipitates high purity calcium hydrogen phosphate. The latter may be converted to high purity phosphoric acid by treatment with sulfuric acid. Either lime or ammonia may be used advantageously as a neutralizing agent.

    摘要： Sheet metal studs in a demountable partition assembly are provided with tabs interlocking adjacent pairs of the studs at each joint against relative lateral movement, to prevent lipping at the panel joints. The tabs are resiliently retractable and are formed with angularly oriented outer surfaces to permit forcible retraction of the tabs by sliding a thin tool blade between a pair of such interlocked studs.

    摘要： An improved stud and demountable partition assembly or wall constructed therewith, the stud being characterized by a single partition member interengaging means projecting from one edge, and double partition member interengaging means from the other edge, whereby the wall is constructed progressively up to that stud, leaving the partition member adjacent to the single partition member free of any connection to the improved stud and thereby completely accessible independently from the remaining wall portions.
