  • Spill-proof drink container assembly
    Patent number: 5560513
    Abstract: A spill-proof drink container is provided with an interior fluid tank having a resilient, diaphragm-like bottom closure and an interior recovery tube co-operating with the bottom closure in sealing relation, with an outer container housing the interior fluid tank and providing a completely surrounding negative pressure passageway, and with a dual-passageway withdrawal tube that cooperates with the negative pressure passageway and with the recovery tube. Negative pressures introduced into the withdrawal tube by the container user cause the diaphragm bottom closure to move downward whereby hydrostatic forces in the contained liquid flow the contained liquid into and through the recovery tube and through the dual-passageway withdrawal tube to the container user creating the negative pressures.

  • Axial piston pump
    Patent number: 5538401
    Abstract: A variable displacement axial piston pump has a plurality of piston bores each connected to an inwardly angled fill port. The fill ports extend from the piston bores inwardly to the working face of the barrel to reduce the diameter of the fill circle of a pump. This decreases the velocity that must be attained by incoming fluid to thereby increase the operating speed at which the pump may be driven where the pump is filled at atmospheric pressure.
