  • Patent number: 9243633
    Abstract: A device for branching a fluidic partial flow off a main flow by a hydraulic pump (10) includes individual main chambers (12, 14, 16, 18, 20) sealed from each other and divided into functional groups, and operates according to the displacement principle. The chambers enable fluid from at least one main flow inlet (22) to be transported from an inlet or suction side to an outlet or pressure side of the hydraulic pump (10) and then via at least one main flow outlet. At least one independent partial chamber (26) is provided for the transport of the partial flow in addition to the main chambers (12, 14, 16, 18, 20). The partial chamber forms part of the pressure side of the hydraulic pump (10) and is connected to an independent partial current outlet (42) separate from the main flow inlet (22) and the main flow outlet (24).

  • Patent number: 7407058
    Abstract: A filter element for filtering fluids has at least one filter unit (12, 14, 16) that is disposed concentrically around the axis of the element. The unit is supported on at least one supporting element (24, 26, 30) in the direction of the flow of the fluid. At least part of the supporting elements (24, 26) is provided, at least on the side facing the filter unit (12, 14, 16), with channels (28) for guiding the fluid. Longitudinal ribs (50) delimit the channels (28), and extend along the supporting element (24, 26) in the form of spiral tracks. The two free ends of each channel (28) emerge at opposite ends of the corresponding supporting element (24, 26). The channels (28) extend continuously along the supporting element, are devoid of multiple deviations in the fluid flow and only partially surround the corresponding supporting element (24, 28) to form a torsional guide for the fluid flow.

  • Patent number: 7374942
    Abstract: A process and apparatus for testing material libraries, in particular catalysts, by means of coupled use of at least two analytical methods, preferably IR thermography and mass spectrometry. Owing to the selected arrangement, the disadvantages of the two previously known individual methods are compensated for: the subsequent selectivity determination for selected sections by means of mass spectrometry invalidates the argument against IR thermography, of only being able to determine activities; the rapid integrated determination of potentially “good” materials via IR thermography prevents an excessive loss of time by needing to test all materials of a library successively with the mass spectrometer.
