Abstract:
1. A wall cleaning kit for a tank having two transparent walls that meet at a corner, wherein each wall has an inner and an outer surface, wherein selected parts of those surfaces require cleaning, the kit comprising: a) an inner element with one side adapted to slide along an inner surface of the tank which is thereby cleaned; b) an outer element with a side that is adapted to slide along an outer surface of the tank; c) a horizontal guide rail adapted to be attached to the tank at the top of the walls, wherein the rail passes above the selected parts and comprises a followable track that assumes the form of a double ogee curve when the track travels around the corner; d) a vertically disposed carriage that is movably attached to the rail, and that extends from the rail to the bottom of the tank, wherein the carriage comprises; e) a programmable motion-control means that controls the horizontal drive means and the vertical drive means; wherein; the inner and outer elements incorporate a plurality of magnetic components on the respective sides of each element which are adapted to slide along the respective surfaces, wherein, when the elements are positioned in pairs opposite each other on a tank wall, a magnetic component in one element is disposed opposite a magnetic component of opposite polarity in the other element of the pair such that an attractive force, which is inversely proportional to the square of the distance between the components, is established between each pair of components thereby magnetically coupling the elements together, with the inner element being pressed against the inner surface and the outer element, which is pressed against the outer surface, is separated from the inner element by a distance equal to the thickness of the wall; the outer element is attached to the shuttle; the programmable motion-control means is adapted to sequentially cause the steps of: whereby the selected areas of the walls are cleaned.
