  • Filter comprising rotatable, disk-shaped filter elements
    Patent number: 7396464
    Abstract: The invention concerns a device for the separation of substances, in particular of solid substances, liquid phases of varied density and/or of gases, from a liquid, by rotation with several filtering elements, which permit the filtered liquid to pass through and which are rotatably supported around a rotational axis inside of a housing, said housing exhibiting an inlet opening for the liquid, at least one discharge opening for the heavy substances separated by rotation and at least one discharge opening for the filtered liquid. In accordance with the invention, a throughflow is provided, in the region or in the proximity of the rotational axis of the filtering elements, for substances exhibiting a density lower than that of the liquid.

  • Filter comprising rotatable, disk-shaped filter elements
    Publication number: 20050029183
    Abstract: The invention concerns a device for the separation of substances, in particular of solid substances, liquid phases of varied density and/or of gases, from a liquid, by rotation with several filtering elements (5, 6, 7), which permit the filtered liquid to pass through and which are rotatably supported around a rotational axis (3) inside of a housing (1), said housing exhibiting an inlet opening (28) for the liquid, at least one discharge opening (44) for the heavy substances separated by rotation and at least one discharge opening (32) for the filtered liquid. In accordance with the invention, a throughflow (48) is provided, in the region or in the proximity of the rotational axis (3) of the filtering elements, for substances exhibiting a density lower than that of the liquid.

  • Method for quality assurance of crimp connections produced by a crimping device and crimping tool and crimping device therefor
    Patent number: 6418769
    Abstract: The method for quality assurance of crimping connections made by a crimping device having an exchangeable tool with two tool parts uses a tool that is provided with an electronic data storage device. The electronic data storage device stores tool-specific nominal data derived from a nominal force-stroke characteristic line of a nominal crimping action of the tool. A crimp connector is fastened to the end of an electrical cable by placing the end of the electrical cable and the crimp connector between the two tool parts and moving the two tool parts relative to one another for carrying out the crimping action. The force-stroke characteristic line of the two tool parts is measured during the crimping action. The measured force-stroke characteristic line is compared to the stored nominal data.
