First Claim
1. 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.

Abstract
A pneumatic transfer apparatus (10) includes a service provider terminal (22) and a customer terminal (24). A carrier (32) is moved through a transfer conduit (26) between the customer and service provider terminals by a differential pressure generating mechanism (28, 30). Each of the customer and service provider terminals includes an actuator mechanism (54, 82). The actuator mechanism is operative to orient an opening in the housing of the carrier with a transfer opening in the transfer conduit. The actuator mechanism is further operative to move an inner shell (100) relative to an outer shell (96) of the carrier so as to bring openings in said inner and outer shells into alignment which enables accessing the interior area of the carrier.
