    Abstract: Disclosed is a method of reducing a haze value in molding compositions including use of colorants selected from anthraquinone colorants, benzimidazolone colorants and perinone colorants. The molding compositions include at least one polyamide and at least one compound of the general formula (I) where x is 1, 2 or 3; R1 and R2 are mutually independently selected from hydrogen, linear C1-C7-alkyl, branched C3-C10-alkyl, unsubstituted or substituted C3-C12-cycloalkyl, unsubstituted or substituted C3-C12-cycloalkyl-C1-C4-alkyl, unsubstituted or substituted aryl and unsubstituted or substituted aryl-C1-C4-alkyl; and Z is selected from C3-C10-alkanediyl, unsubstituted or substituted arylene, unsubstituted or substituted arylene-C1-C4-alkylene-arylene, unsubstituted or substituted heteroarylene, unsubstituted or substituted heteroarylene-C1-C4-alkylene-heteroarylene, unsubstituted or substituted C5-C8-cyclo-alkylene, unsubstituted or substituted C5-C8-cycloalkylene-C1-C4-alkylene-C5-C8-cycloalkylene, unsubstituted or substituted heterocycloalkylene and unsubstituted or substituted heterocycloalkylene-C1-C4-alkylene-heterocycloalkylene.

    Abstract: An apparatus (112) for heating a fluid is proposed. The apparatus (112) comprises at least one electrically conductive pipeline (120) for receiving the fluid at least one electrically conductive coil (110) at least one AC voltage source (114), which is connected to the coil (110) and is designed for an AC voltage to be applied to the coil (110). The coil (110) is designed for generating at least one electromagnetic field by applying the AC voltage. The pipeline (120) and the coil (110) are arranged in such a way that the electromagnetic field of the coil (110) induces in the pipeline (120) an electrical current, which warms up the pipeline (120) by Joulean heat, which is produced when the electrical current passes through conducting pipe material, for heating the fluid.

    Abstract: The present invention relates to a process for concentrating desired particles comprising a carrier-magnetic-separation comprising the following steps a) providing a feedstock which contains the desired particles and an undesired material; b) adding hydrophobic magnetic particles to the feedstock which results in a loaded feedstock containing agglomerates of the magnetic particles and the desired particles or of the magnetic particles and the undesired material; c) separating the agglomerates from the loaded feedstock by a separation method which results in isolated agglomerates, where the separation method is selected from sorting, electric separation, magnetic separation, screening, classification, gravity concentration, and flotation; d) breaking up the isolated agglomerates to obtain a suspension comprising the magnetic particles in desagglomerated form; and e) separating the magnetic particles from the suspension obtained in step d) by a separation method selected from sorting, electric separation, magnetic separation, screening, classification, gravity concentration, and flotation.
