Abstract
Provided herein are pneumatic carriers for use in high speed and/or heavy payload pneumatic carrier transport applications. The carriers incorporate thermally conductive wear bands to remove heat from areas of high friction to areas of low friction and thereby reduce the wear rate of the wear band. In one arrangement, the wear band includes a metallic wire impregnated cloth having metallic wires woven into the matrix of a textile, which forms the wear band. In one embodiment, the wire impregnated within the textile may extend around at least a portion of a carrier such that the wires can transfer heat from a location of high friction (e.g., a bearing surface beneath a carrier) to a location of low friction.
Claims19
A carrier for use in a tube transport system comprising at least one pneumatic tube, said carrier comprising:
- a generally cylindrical containment vessel which defines an enclosed space and which includes a first access to said enclosed space;
- first and second seal bands interconnected with an outer surface of said containment vessel and substantially encircling said containment vessel at first and second spaced locations, wherein said at least one seal band comprises:
- a wire impregnated textile material, wherein wires within said wire impregnated textile material extend about a portion of the circumference of said containment vessel.
A carrier for use in a tube transport system comprising at least one pneumatic tube, said carrier comprising:
- a generally cylindrical containment vessel which defines an enclosed space and which includes a first access to said enclosed space;
- first and second seal bands interconnected with an outer surface of said containment vessel and substantially encircling said containment vessel at first and second spaced locations, wherein said at least one seal band comprises:
- a woven textile material having a first set of fibers extending about a portion of the circumference of said containment vessel, wherein at least a portion of said first set of fibers have a thermal conductivity of at least 15 (W/mK).
A method for use in removing heat from contact surfaces of a pneumatic carrier utilized in a pneumatic tube system, comprising:
- attaching a seal band to an outside surface of a pneumatic carrier,
- aligning metallic wires within said seal band around the circumference of the outside surface, wherein at least a portion of the individual wires within said seal band extend over an arc length of at least one radian;
- launching the pneumatic carrier through a pneumatic tube system, wherein said wires provide a thermal conduction path from a contact point beneath a center of gravity of said carrier to a location.
