  • Power unit for single line pneumatic tube system
    Patent number: 4482294
    Abstract: A pressure-vacuum chamber is mounted in a sheet metal housing having acoustical padding on inner surfaces of walls. The chamber has two vacuum-formed truncated cone members and a longitudinally extending axial partition plate sealingly mounted in inward facing grooves in the members. A flow-through blower is sealingly mounted in an aperture in the plate.

  • Single line pressure-pressure pneumatic tube system
    Patent number: 4407613
    Abstract: A single line, pressure-pressure, pneumatic tube system having a pair of terminals each being capable of dispatching or receiving carriers. Each terminal provided with a blower to provide air flow, tubing connecting the two terminals, a pair of inline valves in the tubing, one facing in one direction and the other in the opposite direction. The valves being so designed that the one near the dispatching terminal automatically closes to permit build up of pressure and the one near the receiving terminal opens to exhaust pressure and slow the travel of the carrier as it approaches the receiving terminal, the terminal having a bleed-off orifice to assure carrier arrival.
