Abstract: Described is a mechanical device and method for cleaning pool cartridge filters. In its essence, the mechanism is comprised of a cylindrical body with a spinning floor and two water tubes. One water tube runs through the middle from top to bottom, and the second water tube runs longitudinally along the inner wall. A filter cartridge is inserted into the body over the center sprayer. A lid is attached after the cartridge is inserted, and the water is turned on. Pressurized water is delivered through holes in the center and side sprayers, flushing the inside and outside of the filter cartridge until clean. There are special holes in the side sprayer which are angled to propel the rotation of the filter cartridge on the spinning floor, insuring a uniform delivery of water along the filter walls. The system runs from a garden hose.

Abstract: A method for converting nickel into a nickel salt solution. Nickel is dissolved and reacted in an oxygen-enriched acidic solution to produce a nickel salt solution as illustrated in the following chemical equation, wherein X is a conjugate base: Ni+H2X+½O2->NiX+H2O.

Abstract: A preferred embodiment of the present invention provides a process for making nickel sulfate by converting nickel metal into nickel sulfate, which may be converted to nickel hydroxide. Nickel metal is dissolved in sulfuric acid and oxygen containing gas is introduced to produce a nickel sulfate solution having nickel sulfate and water as illustrated in the following chemical equation. Ni+H2SO4+½O2?NiSO4+H2O The nickel sulfate is filtered and sulfuric acid is continually added to maintain stoichiometry within a reactor until the nickel metal is dissolved. The sulfuric acid, oxygen containing gas and nickel metal may be heated to facilitate the desired reaction. Then, the nickel sulfate may be utilized to produce nickel hydroxide.

Abstract: A method for making a catalyst having catalytically active material supported on a carrier matrix. The catalytically active material may be a mixed-valence, nanoclustered oxide(s), an organometallic material or a combination thereof. In one method, a metal salt solution is combined with a metal complexing agent to form a metal complex. The metal complex is then combined with a suspension that includes a carrier matrix and the system is subjected to ultrasonic agitation. A base is then added to induce a controlled crystallization of a catalytic nanocluster metal material onto the carrier matrix. The supported catalytic material is particularly useful for catalyzing oxygen reduction in a fuel cell, such as an alkaline fuel cell.
