  • Patent number: 8900455
    Abstract: A filter assembly for filtering a fluid. The filter assembly at least one filter in a housing, an inlet lid mounted over the filter housing and including an inlet for the inlet of fluid into the housing, and an outlet lid mounted over the filter housing and including an outlet for the outlet of fluid from the housing. The assembly also includes an inlet plunger adapted for sealing flow from the inlet when the inlet plunger is biased to a first sealing position, and an outlet plunger adapted for sealing flow to the outlet when the outlet plunger is biased to a first sealing position.
    Type: Grant

  • Patent number: 7905457
    Abstract: Interlocking brackets for filter capsules are provided. According to one embodiment, a filter capsule bracket includes a first bracket portion including a first side having a concave surface and at least one plug; and a second bracket portion including a first side having a concave surface corresponding to the concave surface of the first bracket portion and at least one socket for receiving the at least one plug of the first side of the first bracket, wherein the concave surfaces of the first and second bracket portions are configured to retain a filter capsule when the at least one plug of the first side of the first bracket portion is received by the at least one socket of the first side of the second bracket portion.

  • Patent number: 5905192
    Abstract: Method and apparatus are provided for peak identification of sample peaks in a chromatogram, wherein at least one group of standard peaks in standard peak series is matched to at least one group of sample peaks in a sample peak series so as to perform proper identification of the sample peaks in the sample peak group. In a preferred method, a succession of retention time windows are determined according to the characteristic retention times of the standard peaks and according to steps for determining shift, stretch, and distort parameters. The retention time windows are located with respect to the sample peak series and in accordance with the shift, stretch, and distort parameters so as to capture only certain ones of the sample peaks in the sample peak series. The shift, stretch, and distort parameters are used to position the retention time windows for improved matching of the standard peaks in the standard peak group to the captured sample peaks.
