Abstract: Production of pigmented resin powders by finely dispersing dispersions of pigments in solutions of polymeric materials in at least one organic solvent in water containing a protective colloid while supplying mixing energy, and removing the solvent. A preferred method is to introduce one or more jets of water containing protective colloid at the rate of 5 to 100 m/sec into animpulse exchange chamber together with the dispersion issuing in the immediate vicinity of the orifice(s), and to remove the solvent. The method avoids crosslinking and provides pigmented resin powders of consistently reproducible color which are suitable for conventional powdered-resin coating methods.
Abstract translation: 通过将颜料的分散体在含有保护胶体的水中的至少一种有机溶剂中精细分散在聚合物材料的溶液中同时提供混合能量并除去溶剂来生产着色树脂粉末。 一种优选的方法是将一种或多种含有保护胶体的水，以5-100m / sec的速率引入到脉冲交换室中，同时在紧邻孔口处发出分散体，并除去溶剂 。 该方法避免交联，并提供适合于常规粉末 - 树脂涂覆方法的颜色一致的可再现颜色的着色树脂粉末。

Abstract: 1413356 Fibrids of thermoplastic materials BADISCHE ANILIN- & SODA-FABRIK AG 23 Feb 1973 [25 Feb 1972] 8938/73 Heading B5B Fibrids (i.e. short fibres) of a thermoplastics material are made by introducing a high-speed propulsive jet and a slower-moving stream of a liquid co-currently into a mixing tube arranged coaxially with the jet, whereby a shear gradient is set up in the mixing tube between the highspeed jet and the slower-moving liquid stream, and feeding the molten thermoplastics material through a die into the region of the shear gradient, whereby the thermoplastics material is broken up into fibres by the action of shear stresses within the region of the shear-gradient. Specified thermoplastics materials include polyethylene, polypropylene and their waxes and extended waxes, polyamides, polyesters, polyvinyl chloride and polystyrene. In Fig. 1, the apparatus is enclosed in container 4. Melt is supplied via 6 to outlet orifice 2; the spinning medium, suitably water, is supplied via 5 to the outlet orifice 1 of the propulsive jet; 3 is the impulse exchange chamber or mixing tube. If the relatively slow-moving stream of liquid entrained from the container is replaced by liquid coming from a pump, the container may be dispensed with, as in Fig. 2, where 7 is the feed-line for the slow-moving medium (water) spinning being effected in tube 3 which acts as impulse exchange chamber.

Abstract: - 7 - O.Z. 0050/40470 A control loop comprising a control section, a set value/actual value comparator and a controller is expanded for ultraprecision measurements in such a way that, to detect measurement signals, the control variable connection between the controller output and the control section input is guided via a measured value transducer and, to evaluate and display the measured value, the correcting variable output of the controller is additionally connected to an evaluating circuit.

Abstract: Hydroxylammonium salts are manufactured by a process comprising the catalytic reduction of nitric oxide with hydrogen in a dilute aqueous solution of a mineral acid in the presence of a suspended platinum catalyst at an elevated temperature, wherein the reaction mixture is recycled and the gas mixture, containing nitric oxide and hydrogen, present in the gas space above the reaction zone, is introduced, by means of one or more downwardly directed jets of liquid, consisting of the recycled reaction mixture and issuing from a nozzle orifice, into one or more circulation zones which are present in the reaction zone, are open at both sides, extend in the direction of the entering jet of liquid and are completely covered by the reaction mixture, the reaction mixture leaving the bottom of the circulation zone and containing unconverted gases is deflected, passed upwards in the annular zone externally surrounding the circulation zone, and at the same time reaction mixture of low gas content is recycled from a separation zone located under the reaction zone.

Abstract: High molecular weight linear polycarbonates are prepared by continuous condensation of organic dihydroxy compounds and phosgene in two reaction zones, a mixture of an aqueous-alkaline solution of the organic dihydroxy compound and an aqueous catalyst solution being introduced at the rate of from 1 to 50 meters per second and the phosgene at the rate of from 30 to 300 meters per second into the first reaction zone and condensed, an organic solvent being incorporated into the resultant reaction mixture containing oligomer and polycarbonate and the condensation of the aqueous-organic reaction mixture carried to completion in the second reaction zone by the two-phase interfacial method.
