  • Publication number: 20060116199
    Abstract: In a particular embodiment of the present invention, a system for establishing a wager associated with a game comprises one or more web servers that provide access to an online game for a plurality of users. The system further comprises one or more processors that receive information about a wager offer, wherein the wager offer is associated with the online game. The one or more processors also receive information about a wager acceptance. The wager offer and the wager acceptance combine to form a wager, wherein the wager is associated with at least one wager parameter. The system further comprises a memory communicatively coupled to the one or more processors and that stores information associated with the at least one wager parameter.

  • Publication number: 20050125940
    Abstract: The invention relates to dirt separator module comprising a dirt-separation housing having an inlet and an outlet opening and defining a cyclonic airflow separator, and a suction source fluidly connected with the dirt-separation housing. A separator plate and a cylindrical wall of the dirt-separation housing form a toroidal cyclonic airflow chamber in the dirt-separator for aiding in the separation of dirt from a suction airstream developed by the suction source. The separator plate has an outer diameter smaller than the inner diameter of the cylindrical wall of the dirt-separation housing, creating a gap between the outer edge of the separator plate and the inner wall of the dirt tank. A further embodiment includes dual cyclonic separators fluidly connected through a filter assembly. A further embodiment includes a cyclonic separator in the form of a tangential helical ramp.

  • Publication number: 20050022333
    Abstract: A portable extraction surface cleaner apparatus wherein a surface to be cleaned is heated to an elevated temperature and a cleaning fluid is applied to the surface to be cleaned sequentially or simultaneously. The cleaning fluid is removed from the surface by suction from a vacuum source. Power is applied alternatively or simultaneously to a heating element and to the vacuum source for recovering the deposited cleaning fluid.
