ABSTRACT:
In pneumatic systems for propelling couriers through conduits, a discharge unit employs the momentum of the propelled courier to establish a cushion of air under pressure, which cushion retards the velocity of the courier prior to its discharge. A counter balanced latched hinged plate attached at the outlet of the discharge unit is released by the courier to effect its discharge.
