ABSTRACT:
A pneumatic transmission system is provided. The system comprises a transmission tube having a first end and a second end. A blower adapted to force air from the first end to the second end of the transmission tube is interconnected to the first end of the transmission tube. A vacuum source having a capacity at least as great as that of the blower is connected to the transmission tube proximal the second end. The vacuum source creates a flow of air from the second end of the transmission tube to the vacuum source, thereby decelerating a carrier being transmitted to the second end of the transmission tube.
