Patent ID: 7686547

Claim:
Method comprising: a) applying a pressure differential across a carrier of a pneumatic transport system, wherein the pressure differential causes the carrier to move into a movable chamber of a terminal, wherein the carrier enters the chamber when the chamber is in a carrier receiving position, wherein in the carrier receiving position an end of the chamber is in operative sealed connection with a pneumatic transport tube end, wherein in the carrier receiving position the chamber extends substantially vertical and a longitudinal axis of the end of the chamber is substantially axially aligned with a longitudinal axis of the pneumatic transport tube end, wherein the terminal includes a drive member, wherein the drive member includes therein a drive slot defined by a boundary wall, wherein the terminal includes a cam follower operatively connected to the chamber, wherein the cam follower extends through a cam groove and into the drive slot, wherein movement of the cam follower along the cam groove causes movement of the chamber, wherein the drive member is operative to cause the boundary wall to engagingly move the cam follower along the cam groove; b) subsequent to (a) and with the carrier in the chamber, moving the cam follower along the cam groove to vertically move the chamber from the carrier receiving position to an elevated position relative to the pneumatic transport tube end, causing the end of the chamber to be moved out of operative sealed connection with the pneumatic transport tube end, wherein the longitudinal axis of the end of the chamber in the elevated position is angularly disposed from the longitudinal axis of the end of the chamber in the carrier receiving position; c) subsequent to (b) and with the carrier in the chamber, further moving the cam follower along the cam groove to move the chamber from the elevated position to a presentation position, wherein the chamber moving includes angular movement of the chamber, wherein the longitudinal axis of the end of the chamber in the presentation position is out of axial alignment with the longitudinal axis of the pneumatic transport tube end, and wherein the longitudinal axis of the end of the chamber in the presentation position is angularly disposed from the longitudinal axis of the end of the chamber in the elevated position; and d) with the chamber in the presentation position, causing the carrier to be manually accessible to a user of the terminal.
