  • Patent number: 7188839
    Abstract: A method of playing an entertainment game includes selecting a lead participant who is required to perform at least one qualifying action in a first level of play. The lead participant is rewarded preferably by a monetary reward upon completion of the requisite number of qualifying actions in the level of play. The lead participant may select an ally from a resource pool to assist in performing the qualifying action. The ally shares with the lead participant in the reward. Preferably there are multiple levels of play with higher degrees of difficulty and with greater rewards.

  • Patent number: 6165519
    Abstract: A filter for the adsorption of ingredients from and/or the dispersion of ingredients into a fluid includes a matrix which has a plurality of particles having an inherently active surface or an active surface made of a fluid treating material. The particles are held in place by a moderately viscous binder which is impervious to the flow of the fluid. The particles, however, are made of a fluid pervious material. An insufficient amount of binder is incorporated in the matrix to otherwise completely cover the particles. Thus portions of the active surface of the particles remains exposed to the flow of fluid thereby resulting in tortuous paths of flow through the matrix, thereby assuring contact with the treating particles.

  • Patent number: 5567461
    Abstract: A filter for fluids includes a pair of layers or multiple layers or pairs of material joined together to form a laminate having a fluid contacting surface. A plurality of spaced pockets is formed between the layers of material in the contacting surface. The layers of material are fluid permeable at the pockets whereby fluid may flow through the laminate at the pockets. The fluid contacting surface is fluid impermeable except for the pockets to require the fluid passing through the laminate to be confined to flowing through the pockets. Filter members are in the pockets for removing any contaminants from the fluid. Alternatively, additive materials such as powdered cream or sugar in the pockets dissolve in the fluid passing through the pockets to enhance the fluid.
