  • Patent number: 4886609
    Abstract: A method for the removal of scale from the interior of producing oil and gas wells is disclosed. The method comprises introducing a mixture of an aqueous mineral acid, a mutual solvent, and an alkyl or aralkyl polyoxyalkylene phosphate ester to the interior of the well. The phosphate ester maintains the acid and mutual solvent in a micellar emulsion state. The mixture is retained in the well to allow the acid to solubilize the mineral deposits and then the mixture and solubilized mineral deposits are removed from the well interior.

  • Patent number: 4886554
    Abstract: A solar roofing assembly is provided including a roofing membrane, a plurality of insulation blocks disposed as a layer on top of the roofing membrane, a plurality of pavers disposed as a layer on top of the plurality of insulation blocks, and a plurality of photovoltaic cells, each supported on a respective paver. In a second embodiment, each paver has a respective photovoltaic cell bonded to the top surface of the paver and has a respective insulation block bonded to the bottom surface of the paver forming a shop assembled, three-layer unit. The insulation block is also tapered with one side edge being thicker than an opposite side edge so that rain water will run off the top surface of the photovoltaic cell. The three-layer paver units are arranged on top of the roofing membrane, so that the top surfaces of the photovoltaic cells face south or in the direction of increased sun exposure. The insulation blocks have interlocking side surfaces.

  • Patent number: 4871483
    Abstract: The present invention involves new anti-foam compositions which control foaming in aqueous systems and by nature of their unique cloud point characteristics are insoluble and particulate above their inverse cloud point, and soluble below it. This property makes them non-depositing defoamers. As the defoamed aqueous system cools down these novel products become soluble, preventing insoluble material (pitch) from depositing on process equipment and matter being processed.

    Abstract: A process and apparatus is provided for making a rubber-like product from rubber scrap, such as recycled tire scrap. The process includes mixing the rubber scrap with from 1 percent to 15 percent, with respect to the weight of the rubber scrap, of added sulphur, and applying a pressure thereto of about 1000 to 3000 pounds per square inch for 1 to 10 minutes at a temperature of from about 250 degrees F. to about 450 degrees F. In addition, 1 to 8 percent, with respect to the weight of the rubber scrap, of antioxidants and antiozonants are added to the mixture of rubber scrap and sulphur. The sulphur is free sulphur. Derivative sulphur compounds, or like vulcanizing agents, can be added in place of the free sulphur of about 1 to 45 percent of the weight of the rubber scrap. The rubber scrap is buffing of recycled tire rubber, or powder made from recycled tire rubber. An apparatus for carrying out the process is also provided.
