  • Patent number: 4612056
    Abstract: The present invention is a method and an apparatus for reducing marine growth on an offshore oil platform member. The device uses a buoyant member coupled with a sleeve to scrape the exterior surface of the platform members. The buoyant component floats on the surface of the water and takes advantage of the ocean energy (i.e., the variation of the water's surface height due to the tidal and surge responses) to move the device up and down on the member. The liner and the buoyant member are adjusted for size and buoyancy to ensure that scraping occurs in the areas of the members that are most vulnerable to attachment of marine organisms.

  • Patent number: 4597124
    Abstract: The present invention relates to a method and apparatus for cleaning upholstery which involves minimal risk of dye bleeding and which is reasonably effective. The invention uses a hand-held applicator and a remote unit. A jet nozzle on the hand-held applicator sprays cleaning solution onto the upholstery. Secured adjacent to the jet nozzle is a brush which imparts mechanical energy to the upholstery and aids in cleaning. Disposed above the brush is a vacuum head that removes the cleaning solution from the upholstery. Air is induced into the vacuum head by a blower secured within the remote unit. The air effectively lifts the cleaning solution from the upholstery and carries the cleaning solution into the vacuum head. Once inside the vacuum head, the combined mixture of air and cleaning solution is directed through a hose into a recovery tank secured within the remote unit where the air and cleaning solution are separated.

  • Patent number: 4595420
    Abstract: The present invention entails a method and apparatus for cleaning and maintaining large areas of low to medium pile carpet, such as is found in hotels, airports, etc. The invention employs a mobile carpet cleaning machine which is propelled over the carpet to be cleaned. The principal features of the carpet cleaning machine are an elongated cylindrical brush, a vacuum system with a floating vacuum head, and a blower. In operation the cylindrical brush is set into a rotating motion and engages the underlying carpet. A cleaning solution is sprayed onto the rotating brush which in turn transfers the solution onto the underlying carpet. The vacuum head then passes over the carpet directly behind the rotating brush. The blower pulls air through the vacuum head and the vacuum head effectively picks up a combined mixture of air and solution. This mixture of air and solution is pulled upwardly from the vacuum head into the top of a recovery tank.
