  • Patent number: 6314864
    Abstract: A closed cavity piston assembly includes a piston body, a separately formed piston cap sealingly joined to the body, and an elongated stem integrally formed with one of the piston body or the cap. In one embodiment, the stem is integrally formed with the piston body. In another embodiment, the stem is integrally formed with the piston cap and slidably journaled in and sealed to a hole in the bottom of the piston body. The cap of the piston assembly also has a surface for engaging a slipper. In either case, a fluid passageway extends through the stem, body, and cap of the piston assembly. The passageway is remote from the side wall of the piston body and fluidly isolated from the main interior cavity of the hollow piston body once the cap and body are sealingly joined together. The piston assembly can be pivotally attached to a slipper that has its own fluid passageway, which registers with the passageway in the cap, to provide fluid for slipper lubrication and balance.

  • Patent number: 6311847
    Abstract: A method of reblending aggregate includes delivering aggregate of various sizes to the classification tank having a plurality of stations with primary and secondary discharge valves. The tank is then calibrated to determine raw feed analysis, discharge rates and the flow multipliers needed to develop a mathematical model of the tank. Inputting the calibration information data and the desired production specification into a computer allows the tank to be operated and controlled with appropriate adjustments in discharge rates and valve percent settings at each station. This method provides more accurate control than the existing min-max control methods. The apparatus for this method includes the tank, a pumping device, and a computer interconnected with a PLC and electrohydraulic mechanisms for valves at each tank station such that both the discharge rate from each station and the valve percent settings of the individual valves at each station are variable and controllable.

  • Patent number: 6295747
    Abstract: The present device provides a baggage tag attachable to the handle of a piece of baggage for displaying indicia of the identification and destination of a passenger owning the baggage. The tag has a first or base ply and a second tear resistant ply or liner. The underside faces of the base ply and tear resistant liner are arraigned for engagement with one another. An adhesive is disposed between the base ply and the liner for releasably sealing them together. It is preferred that a release coating be applied to the underside face of the liner. This allows the removal of the liner from the adhesive layer, allowing the adhesive to remain with the base ply. The base ply and liner each have cuts proximate one end thereof defining a claim stub. Upon removal of the claim stub, a length of the underside face of the base ply adjacent the base ply cut is exposed with the adhesive permitting the to tag ends to be secured around a bag handle.

  • Patent number: 6293863
    Abstract: A seed package handling system is provided for a test plot combine. A seed packaging assembly in the combine packages the seeds and deposits the packages onto a conveyor, which transports the packages to a first hopper. After the first hopper has received a predetermined quantity or weight of seed, the first hopper is raised on an elevator and then tilted so as to dump the seed packages into a larger second hopper. After the second hopper has received a predetermined quantity or weight of seed, the second hopper is tilted to discharge the seed packages into a wagon separate from the combine, which transports the seed packages to a processing facility. The movement of the conveyor and first hopper is controlled by a PLC.
