Abstract:
An apparatus comprising:a transfer conduit;a differential pressure generating mechanism operatively connected to the transfer conduit;a carrier, wherein the carrier has a first axial end and a second opposed axial end disposed from one another in an axial direction, wherein the carrier has a central axis in the axial direction, wherein the carrier is movable in the transfer conduit responsive to differential pressure produced by the differential pressure generating mechanism, wherein the carrier includes a housing bounding an interior area, and wherein the housing includes an opening therethrough and a movable member movably mounted in supporting connection with the housing, and wherein the movable member is rotatably movable relative to the central axis between a closing position in which the movable member closes the opening and an open position wherein the movable member is moved to enable accessing the interior area through the opening;an actuator mechanism wherein the actuator mechanism operatively engages the movable member and selectively moves the movable member between the open and closing positions.
