Abstract: An apparatus for electroplating an article, such as a printed circuit board, includes a tank filled with electrolytic solution, a clamp for retaining the article fixed in place within the solution and a movable roller assembly disposed within the solution. The roller assembly includes a pair of vertically disposed, parallel rollers that are rotatably coupled to a rigid frame, with one roller preferably being spring biased towards the other roller. In use, the application of electrical current causes metal ions present in the solution to plate out on the article. To promote greater plating within through-holes or other similar surface depressions in the article, the roller assembly is linearly displaced by a motor-driven linkage so that the pair of rollers squeegee opposing surfaces of the article.

Abstract: An improved apparatus for treating plate-like work pieces with a designated chemical solution, including printed circuit boards, including (1) a tank for holding the chemicals, agitation frame and roller assembly, (2) a frame that holds two rollers covered in brush or sponge like material, (3) a guide rail assembly attached to a roller frame, (4) a slotted block attached to a guide rail (5) a disk with a bottom shaft coupling and top pin to move slotted block, (6) a low rpm motor that attaches to disk coupling.

Abstract: A flooded cell type lead-acid battery includes a separator-filter material that is enveloped around a porous electrode, housed in a frame and placed in a cell compartment horizontally from it's opposite electrode. Flow is moved up through a porous electrode assembly using a miniature corrosion resistant pump. The separator filter material allows electrolyte to pass uniformly between electrodes and return from top overflow in a closed loop continuous flow. The resulting economically efficient battery assembly exhibits increased efficiency and cycle life by reducing the layer of hydrogen gas and sulfates coating the electrode reaction, and short-circuiting between vertical cell group.

Abstract: An improved method to enhance the air quality of a typical room, which includes:(1) A planter with air inlets and fan suction to exchange air, (2) A sealed environment that allows plants to grow and exchange air. Optionally, the cover can be removed and still achieve improved air quality. (3) Filter material that allows for a clean environment and easy maintenance of unit.

Abstract: A beach chair with an improved method to enhance the comfort of audio listening by incorporating acoustical speakers integrated into top portion of a beach chair. Optionally, the chair has a pouch to hold audio and other items.
