A system for transporting one or more items is provided. The system includes: a transportation tube disposed at least partially underground or at least partially above ground; a transportation pod to secure items therein for transport; a transportation actuator to propel the transportation pod through the transportation tube, the transportation actuator including at least one cable configured to interface with the transportation pod, the at least one cable being driven by a motor to move the cable and the transportation pod through the transportation tube; a first access point located proximate a first end of the transportation tube; and a second access point located proximate a second end of the transportation tube. Each of the first and second access points includes an opening configured to allow the transportation pod to be received into or removed from the transportation tube.

A pharmaceutical transport system may include a pneumatic tube network and a pharmaceutical transport cleaner. The pharmaceutical transport cleaner may include a cylindrical body, and a rotatable cleaning band extending around the cylindrical body to contact and clean adjacent portions of the pneumatic tube network as the cylindrical body moves through the pneumatic tube network.

A deboned poultry meat batch to continuous feed system using a hopper input transferring the meat through a vacuum fill to a low pressure gravity separation small volume batch tank. The low pressure gravity separation small volume batch tank is connected through a rotary valve to a larger lower pressure level-maintenance tank with a tight parameter pressure regulation system to maintain a consistent flow output.

A tubular transportation system is disclosed for transporting one or more passengers or one or more cargos via a capsule along a predetermined route. The tubular transportation system has: (1) a plurality of substantially evacuated tubes arranged along the predetermined route, where each tube is maintained at a pressure that is below atmospheric pressure; and (2) means for maintaining within each tube in the plurality of substantially evacuated tubes, a gaseous composition comprising a mixture of a first percentage, x, of hydrogen and a second percentage, (100-x), of air, and wherein the first percentage, x, of hydrogen is picked based on a predetermined power value and a leak rate associated with the tube.

Provided herein is a pneumatic carrier having a leak resistant cargo area where first and second mating shells form the carrier. To provide a leak resistant cargo area, the one embodiment of the carrier employs a cantilevered sealing element on a first sealing periphery of the first shell. A free end of the cantilevered sealing element is configured to engage a sloped surface on a second shell. As the shells close, the sealing element slides down the sloped surface to form a seal between the shells. The use of the cantilevered sealing element in conjunction with the sloped surface reduces the compressive force required to form a seal between the shells.
