  • Patent number: 7957657
    Abstract: A measurement module for a printer generally includes a page diverter mechanism configured to selectively divert a sheet of media from a main media path to a module media path; a rotating drum configured to receive the media from the module media path and to affix the media on an outer surface of the drum; a measuring device spaced adjacent to the drum and configured to measure as aspect of the media affixed to the surface of the drum; and a sheet transport configured to remove the media from the drum. According to one embodiment, the module may include a drum with an electrostatic hold-down mechanism that captures a sheet and an axially translating measuring device that is configured to read the entire surface as the drum rotates. The measurement module also allows the printed media to cool to eliminate problems with color measurements due to thermo chromaticity.

  • Patent number: 7954642
    Abstract: An elutriation column is installed in a separation tank. The elutriation column includes a vertical separation column having a first side feed arm and a second side overflow arm spaced above the first side feed arm. Water is forced upwardly through the vertical separation column at a controllable velocity. A solid feed mixture is fed through the first side feed arm to the vertical separation column. Water from the tank rising in the vertical separation column at the controlled velocity causes targeted floater materials to move upwardly in the vertical separation column and heavier sinker materials to continue to sink. The floater materials flow from an outlet in the side of the separation tank into the recovery tank. At a discharge, lower end of the vertical separation column, the heavier sinker materials are removed from the separation tank. A mechanism is provided for purging undesirable materials that can cause plugging from the feed arm.
