Abstract: A terminal for connection between sections of a pneumatic tube has upper and lower end walls having respective ports connected to tube sections. The lower end wall also has offset from the respective tube section an outlet port. A rotor pivotal between the end walls between a pass-through position and an intercept position has a pass-through tube aligned between the tube sections only in the pass-through position and an intercept tube aligned between the tube sections only in the intercept position and aligned with the outlet port in the pass-through position. A closing plate between the rotor and the lower wall has an axially throughgoing aperture and is displaceable between a closed position blocking the outlet port and with the aperture over and permitting movement through the lower port and an open position with the aperture over and permitting passage through both the lower and outlet ports.

Abstract: A carrier for a pneumatic tube transport system has a rigid sleeve centered on an axis and having an axially open end, a collar coaxially surrounding the sleeve and formed with a radially inwardly directed edge, and a cover fittable axially over the sleeve in a closed position axially closing the sleeve end and formed with a radially outwardly directed edge closely juxtaposed with the collar edge in the closed position. A pivot defines a pivot axis parallel to the sleeve axis for pivoting of the cover about the pivot axis between the closed position and an open position angularly offset therefrom and unblocking the sleeve end. A compressible seal ring is engaged between the cover and the ring and seals between the cover and the ring in the closed position.
