  • Patent number: 7504025
    Abstract: A floating self-propelled cleaning device (10) for water surfaces, in particular swimming pools, comprises a central floating body (11) and two side floating elements (12) to it connected at opposite sides by two arms (14) to which two net-shaped collecting containers (13) are fastened. The net-shaped containers (13) have openings (17) that allow the inlet of impurities, but prevent the outlet thereof during possible stops or under the action of waves that can occur during the travel on the water surface. The floating device (10) is driven by propelling means (20) and (30) that substantially cause the side floating elements (12) to rotate about an instantaneous centre of rotation located approximately at the central body (11). The rotation of the side floating elements (12) is associated to a shifting movement caused by at least a distribution element (15) movable with respect to the floating body (10).

  • Patent number: 7468128
    Abstract: A fluid pollution prevention system for preventing the discharge of hazardous waste from a bilge of a marine vessel. The system includes an continuous sidewall that defines a vertically enclosed volume. When positioned within a bilge, the sidewall forms a barrier to petrochemicals floating on a fluid surface within the bilge. An opening near a base of the sidewall permits fluid from beneath the fluid surface to enter the vertically enclosed volume. Such fluid is substantially free of petrochemicals and may be removed form the vertically enclosed volume. Accordingly, by pumping fluid out of the enclosed volume, fluid may be removed form the bilge substantially free of petrochemicals. In one arrangement, the vertically enclosed volume may be sized to receive a bilge pump.

  • Patent number: 7425260
    Abstract: The present invention discloses a separation passageway module comprising a plurality of inclined plates, at least one suction pipe, and a buoyancy regulator. The inclined plate passageways are comprised by a plurality of inclined parallel plates. The inclined plate passageways have an opening at either the lower end or the upper end. In the case of having an opening at the lower end, suspension flows into the passageways from the lower end to carry out settling separation and to thereby generate clear liquid at the upper end of the inclined plate passageways. On the other hand, in the case of having an opening at the upper end, suspension flows into the passageways from the upper end to carry out floating separation and to thereby generate clear liquid at the lower end of the inclined plate passageways. One end of the suction pipe is connected to the upper end or lower end of the inclined plate passageways for drawing the clear liquid.
