Abstract: An integral alcohol preparation device (10) or like type of fluid applying device includes an absorbent material or pad (11) for containing alcohol or other fluid, a fluid impermeable material, for example of metal foil (20) lined with plastic (21), as a selectively openable fluid tight chamber for the pad and fluid contained therein, and the pad and fluid impermeable material being attached as a substantially integral assembly. Being so attached, a method of using such a fluid applying device, then, may include the steps of manipulating the fluid impermeable material to open the chamber and to expose the pad and fluid contained therein without breaching the integrity of the several parts individually or collectively, and applying the fluid from the pad to an external surface. Further, a method is disclosed for making an integral fluid applying device. In an alternate embodiment a one piece fluid applying device is formed of flexible material that is folded to form a chamber to contain a fluid.

Abstract: The disclosure relates to a coin counter and wrapper holder for use with conventional paper coin wrappers and to a method of counting and wrapping coins. The device includes a base from which pedestals project upwardly, each pedestal terminating in a circular end face. Each pedestal fits inside and forms a support for the lower end portion of a conventional paper coin wrapper of a specific denomination. Also mounted to the base is an upper wrapper support which has a U-shaped slot proportioned to fit around the outside of each coin wrapper. Each of the pedestals is proportioned so that the distance from its top surface to the top surface of the upper wrapper support is the same as the height of a stack of coins intended for a particular wrapper. The distance between the top of each pedestal and the base is arranged so that each coin wrapper will abut the base at one end and be flush with the top surface of the upper wrapper support at its opposite end. An accurate and speedy coin count is thus assured.

Abstract: A surfing wave pool assembly has a construction so that a continuous front breaking, surfing wave is established. This permits body surfers or surfboards to surf on the forward edge of this advancing wave for most of the length of a pool. The continuous wave front is established by the rapid discharge of water from an elevated reservoir into the deep end of the pool over a reef. A substantial amount of water in the entire assembly is saved by utilizing an elevated floor in the reservoir and a restricted area conduit from the elevated reservoir to openings at the deep end of the pool. The elevated reservoir establishes a sufficiently high head of water to create a surfing wave, yet the elevated floor and the restricted area conduit means substantially limit the volume of water in the assembly required to create the surfing wave.

Abstract: A mixer/charger is used simultaneously to mix and electrically to charge a fluid or fluid-like material, and such electrically charged product is distributed into another fluid for various purposes. In one case the charged product may be mixed with particulate matter used to form smoke--an apppropriate polarity can cause repulsion of the smoke producing particulates thereby to reduce agglomeration and to maximize the suspension time of such particulates in surrounding environment. Alternatively, by distributing the charged product into particulate containing fluid and selecting the polarity such that such particulates tend to agglomerate, expeditious removal of such particulates can be accomplished. The charged product also may be used for distributing mist, distributing ionic material in air, e.g. for sense of wellbeing, and for seeding clouds.
