Abstract: A process for fractionation of dairy whey is described which enables various whey constituents, in particular, alpha-lactalbumin and beta-lactoglobulin, to be recovered in substantially pure form. Lactose may also be recovered. The mineral content of raw whey is reduced so that the calcium content is less than 120 parts per million. Thereafter, the whey is treated to allow the lactose to crystallize out for removal and selectively to flocculate the alpha-lactalbumin, leaving a liquor containing substantially pure beta-lactoglobulin.

Abstract: The present invention is directed toward a toy water gun which is operated by selectively releasing water from a water reservoir pressurized with air. The present invention has a manually operated pump incorporated into the design. As the pump is cycled, water and air is drawn from a water storage tank. Once drawn, the water and air are forced into a pressure reservoir. As the amount of water and air forced into the pressure reservoir increases, the pressure on the water within the pressure reservoir increases. The pressure of the water and air within the pressure reservoir increases with each cycle of the pump, until the pump can no longer overcome the pressure of the water and air within the pressure tank. The pressurized water and air within the pressure tank has an avenue of release that is regulated by the trigger mechanism of the invention. When no force is applied to the trigger, the pressurized water and air are held at bay with no means of release.
