Abstract: An integrated process and system for the cleaning of any body of water in need of periodic cleaning, including but not limited to a swimming pool or spa. A submersible water filtration apparatus comprises a housing unit, an impeller driven by an electric motor powered by batteries, an inlet where fluid, such as water, is drawn inwards into the submersible water filtration apparatus, an outlet for returning filtered water into the body of water, and at least one filter zone.

Abstract: A rechargeable robotic pool cleaning apparatus having a first water pump for providing a downward thrust force, a second water pump for providing at least a rearward thrust component, and a third water pump for providing at least a forward thrust component, the apparatus being buoyant when the pumps are not activated and including adjustable flap valves, baffles and nozzles to alter the outflow direction of at least some of the jet streams of water produced by the pumps so as to produce any one or more of a vertical, forward, rearward, and sideward thrust component depending upon the positioning of the baffles and/or nozzle members. At least one main controller is electronically coupled to a rechargeable power source for controlling the operation of the pumps in various combinations for moving the apparatus both vertically and horizontally in the body of water.

Abstract: Robotic apparatus cleans swimming pools and has road and pulley wheels with belts thereon, on opposite sides and drive motors that rotate a wheel on each side to move the frame along a pool surface. Pairs of outside wheels have friction surfaces to engage pool surfaces to also moving the frame. Forward and rearward brush assemblies are driven to brush the pool surface. Oppositely facing and angled duck bill valves allow water into free volumes in the frame and are covered by a filter bag for filtering out debris under the action of a dual pump assembly that pumps water out through a pair of outlet opening in a top of the frame. A computer processor controls the drive motors and pump assembly to move the frame along programmed paths and rechargeable batteries power the drive motors, pump assembly and computer processor.

Abstract: A hard metal or non-metal member can be formed or shaped to have varying amounts of curvature and tapering by passing the member through a forming channel defined by two sets of opposed, axially displaceable rollers which can be dynamically moved horizontally and vertically in a predetermined range. The rollers are controlled by a computer, a translator, and a electro-mechanical displacement system such as a servo motor. Using data input by a user or preprogrammed instructions containing displacement instruction in the computer, the computer can subsequently instruct servo motors, via a translator, to move the rollers in the available axial directions. The servo motors may include a mechanism for converting rotational movement into fine linear mechanical movement of the rollers. The timing and rate of movement, direction, and force of the roller can be controlled to form and shape the member into a specific contour of curves or tapering sides.

Abstract: A method and apparatus for shaping an elongated member so that it has a smoothly varying shape along its length utilizes first and second elements which define an aperture therebetween. The elements are advantageously roller elements having grooves around their circumference which change in size and shape. A core die can be used for creating the interior of the element and a fiber weave can be wrapped around the core die to create the body of the elongated member. The core is pulled through the aperture between the first and second elements as the elements rotate in opposite directions to create the varying shape.
