  • Patent number: 10876005
    Abstract: The invention concerns a process for manufacturing a dry mineral pigment containing a product formed in situ by the multiple reaction between a calcium carbonate and the product or products of reaction of the said carbonate with one or more moderately strong to strong H3O+ ion donators and the product or products of reaction of the said carbonate with gaseous CO2 formed in situ and/or originating from an external supply and one or more compounds of formula R—X together with the mineral pigment obtained by the process, and its applications in the field of paint and/or plastics.

  • Patent number: 9957391
    Abstract: The present invention relates to the field of processing thermoplastic polymers, particularly the present invention relates to a process for manufacturing compacted material suitable for the use in thermoplastic polymers without a compounding step, comprising the steps of a) providing at least one primary powder material; b) providing at least one molten surface treatment polymer; c) simultaneously or subsequently feeding the at least one primary powder material and the at least one molten surface treatment polymer into the high speed mixer unit of a cylindrical treatment chamber; d) mixing the at least one primary powder material and the at least one molten surface treatment polymer in the high speed mixer, e) transferring the mixed material obtained from step d) to a cooling unit, as well as the compacted material obtained by this process and its use in thermoplastic polymers.

  • Patent number: 7458792
    Abstract: The invention relates to a sintered metal rotor of a rotary piston pump, comprising a pot-shaped base (1) and a journal element centrally projecting from the bottom of said base (1). Said journal element comprises a base section and an adjoining connecting claw section (2) for a coupling element to be joined thereto. The rotor is characterized in that the connecting claw section (2) is configured in the form of two prominent single webs (3). Said single webs (3) are located at a diametrical distance to each other in the periphery of the cylindrical base section in one area each that is limited, in terms of its periphery, to not more than 100°. and radially to not more than 25% of the diameter of the cylindrical base section. The two connecting claw single webs (3) are pressure-sintered by means of single pressure rams that are designed for the cross-sectional areas thereof and that are actuated separately from the sinter pressure rams required to produce the rotor.

  • Patent number: 5537811
    Abstract: A method and apparatus for simultaneously cleansing and grading yarn produced by a spinning or spooling machine with a plurality of spindles or primary spools. One spindle processor is associated with each spindle. The spindle-processor grades in a grading plane containing a cleansing envelope. All yarn defects located outside the cleansing envelope in the grading plane are considered unacceptable defects and are excised from the yarn.
