  • Patent number: 7056722
    Abstract: A sterile method for preparing stable thrombin component from a single donor's plasma in which the thrombin component is harvested simultaneously from the clotting and adhesive proteins component from the same donor plasma in less than one hour. The combined components provide an improved biological hemostatic agent and tissue sealant by virtue of its freedom from the risk of contaminating viruses or bacteria from allogenic human or bovine blood sources. The thrombin provides polymerization of the clotting and adhesive proteins in less than five seconds, and is sufficiently stable to provide that fast clotting over a six hour period. Further, the clotting times can be predictably lengthened by diluting the thrombin with saline.

  • Patent number: 6931848
    Abstract: The present invention provides heat exchanging elements for use in Stirling engines. According to the present invention, the heat exchanging elements are made from muliple platelets that are stacked and joined together. The use of platelets to make heat exchanging elements permits Stirling engines to run more effiecient because the heat transfer and combustion processes are improved. In one embodiment, multi-stage combustion can be introduced with platlets, along with the flexibility to use different types of fuels. In another embodiment, a single component constructed from platelets can provide the heat transfer rquirements betweeen the combustion gas/working gas, working gas in the regenerator and the working gas/coolant fluid of a Stirling engine. In another embodiment, the platelet heat exchanging element can recieve solar energy to heat the Stirling engine's working gas. Also, this invention provides a heat exchanging method that allows for multiple fluids to flow in opposing or same direction.

  • Patent number: 6855052
    Abstract: A gaming device having a first chance opportunity and a second, serially dependent, chance opportunity is provided. The first chance opportunity is preferably a multiple reel game having a special outcome for triggering the second chance opportunity. The second chance opportunity is preferably a plurality of wheels rotatably coupled to a tower atop the reel game. The first of the wheels will spin and provide an outcome upon a specified outcome of the reel game. Each successive wheel will spin when a specified outcome is depicted on a previous wheel. This will continue until either the specified outcome does not occur or the last wheel is spun. In another version, plural wheels are each uniquely related—one to a given reel, such that a certain reel outcome will energize its associated wheel only. Multiple wheels, when synchronized to a certain outcome, lead to a bigger wheel for a jackpot.

  • Patent number: 6808675
    Abstract: A bag, method of manufacture and process are disclosed for the cryopreservation of thermolabile substances. The bag is characterized as having substantially uniform thickness throughout its length and height. The bag features a radiused peripheral edge wall for stress relief and to provide the constant cross-section. A peripheral flashing circumscribes the radiused edge wall and provides a suitable purchase area for sealing so that the thus formed bag is less susceptible to fracture particularly when exposed to cryogenic temperatures. The uniform thickness of the bag promulgates uniform heat transfer to and from the contents of the bag in relation to any surrounding medium at a different temperature. The bag affords more space for efficient storage and reduces heat invasion into the contents of the bag when a plurality of bags are placed with their larger planar surfaces in contact with each other.
