    摘要： Chitosan-containing blends and methods of dissolving and using chitosan are disclosed. A blend includes a solid acid or a solid agent that generates a proton in situ in the presence of water mixed together with a dry solid chitosan, and may optionally contain other components. The blends are in a dry, free-flowing, particulate form. Methods of dissolving a blend typically comprise adding a quantity of the blend to a low volume of water and mixing until the chitosan and solid acid or solid agent are dissolved and then further diluting this mixture by the addition of water, or used as-is. Devices containing the blends are also described along with methods of using the devices, such as for controlled release of solubilized chitosan in a body of water, such as a stream, containing impurities (e.g., particles, sediment, or suspended matter or dissolved substances) to cause flocculation or precipitation of such impurities.

    摘要： A value engine for a gaming machine generally determines a cash value for player cards, symbols, or other gaming indicia even though the indicia does not form a winning outcome. The value engine may determine the cash value for the indicia at various times or stages during a game. The cash value may be presented to the player, and the player may be permitted to accept or decline the cash value. If accepted, the cash value may be paid out to the player. If declined the player may continue playing the game. The value engine is may be used with or implemented as part of a variety of wagering games and presents a challenging and engaging choice to players to to further continued play and entertainment at a gaming machine.

    摘要： The present invention is directed to a device (50) for providing filtration of air. The device includes a body (70) and a cover (72) with each having endless mating structure (76) and (78) which may be welded together thereby mechanically pinching a flat sheet filter media (74) and holding it in place. The cut edge of the filter media (74) is encapsulated. The filter media (74) is held outwardly from bottom (92) of body (70) by gussets (90) to provide sufficient area for air to pass through. Inlet openings (110) are provided between top (94) and endless mating structure (78) in a fashion which allows top (94) to be attached to a flat wall of a sealed housing of a type used for disk drive systems.
