    摘要： Process for the single-bath dyeing of blends of cellulose fibers and synthetic polyamide fibers with reactive dyestuffs and nonreactive metal complex dyestuffs according to a continuous or semi-continuous method of the pad dyeing technique, by applying to these fibrous materials aqueous padding liquors which contain alkaline agents in addition to combinations of the abovementioned dyestuffs, and then, optionally after intermediate drying, submitting the material so treated in the alkaline medium to the action of heat or allowing it to dwell at room temperature or at slightly elevated temperature for the fixation of the dyestuffs.

    摘要： A method of measuring or measuring and controlling the toner concentration of a developer circulating in an electrophotographic reproduction machine wherein a test charge pattern based on toner concentration is formed independent of the photoconductor, the test charge pattern is developed together with the photoconductor exposed to produce an image, optical properties of the developed test charge pattern are measured and toner is added to the developer based upon the measurement. An apparatus including electrodes for producing a test charge pattern which are so arranged in the electrophotographic reproduction machine that together with the photoconductor they can be moved past the operative devices in the electrophotographic cycle, sliding contact rings and/or wiper contacts for applying potential to the electrodes from a voltage source and comparative light beams from the same source for carrying out the measurement of a developed test charge pattern. One of the beams is affected by the developed test charge pattern while the other is an unaffected reference beam. The apparatus also may include a controlling device for the addition of toner to the developer which is responsive to the optical property of the test charge pattern.

    摘要： A water-insoluble monoazomethine dyestuff of the formula
    WHEREIN Ar is an aromatic or heterocyclic radical which contains at least one substituted sulfonic acid amide group, an optionally substituted carboxylic acid amide, acylamino, sulfonylamino, urea, carboxylic acid or laked sulfonic acid group or a -NHCOgroup contained in a heterocyclic ring, and wherein the benzene nucleus a may contain substituents which are valuable pigments, especially suitable for printing pastes. They may also be used for the pigmentation of high-molecular organic material, for example of cellulose ethers and esters, polyamides, polyurethanes or polyesters, acetyl cellulose, nitro cellulose and natural or synthetic resins, for polyolefins, rubber, casein, silicon and silicon resins, individually or in mixture with one another. The new pigments are characterized by high fastness properties and especially have a considerably improved fastness to light and to solvents.

    摘要： Sulfided platinum on carbon catalysts being useful in the selective hydrogenation of halonitroaromates are obtained by saturating a particulate platinum on carbon catalyst with hydrogen in an acidic aqueous medium and treating it with defined amounts of a sulfidizing agent. Said catalysts maintain their activity and selectivity for numerous hydrogenations.
