  • Patent number: 8992780
    Abstract: The invention provides methods and compositions for reducing the malodorous sulfide gas released by a wastewater treatment system. The method preserves the vitality of waste consuming organisms within the system.

  • Patent number: 8992813
    Abstract: A component made of at least one thermoformable material, having a first layer made of a first material, a second layer made of a second material, and a third layer made of the first material. The three layers form a sheet, which is formed to various shapes, depending upon the part that is to be created. The sheet may be formed to produce the bumper of an automobile, a door panel for an automobile, a flotation device, such as a pontoon for a pontoon boat, or the like. The first and third layers are SMC, and the second layer, or “core,” is disposed between the first and third layers, allowing the strength of the first and third layers to be used more efficiently, compared to a sheet having only the first and third layers, and no core.

  • Patent number: 8992814
    Abstract: A method for dry casting concrete block using a resilient mold having a cavity for forming a block face and a form having a block body forming cavity. The form may be offset from the mold to provide steps where the block face joins the body for aligning stacked blocks. Alternately, the form cavity may have a dimension smaller that the height of the block face and can be offset to form a step between the block face and either the top or bottom of the block. Alternately, an insert may be placed in the form adjacent the mold for forming a downwardly projecting lip along the back of the block. Blocks are formed using a dry cast concrete block machine. After casting, the form is removed from the block. The block remains supported on the mold until after it has cured.

  • Patent number: 8992815
    Abstract: Disclosed is a method of producing a chemically pure and stably dispersed organic nanoparticle colloidal suspension using an ultrafast pulsed laser ablation process. The method comprises irradiating a target of an organic compound material in contact with a poor solvent with ultrashort laser pulses at a high repetition rate and collecting the nanoparticles of the organic compound produced. The method may be implemented with a high repetition rate ultrafast pulsed laser source, an optical system for focusing and moving the pulsed laser beam, an organic compound target in contact with a poor solvent, and a solvent circulating system to cool the laser focal volume and collect the produced nanoparticle products. By controlling various laser parameters, and with optional poor solvent flow movement, the method provides stable colloids of dispersed organic nanoparticles in the poor solvent in the absence of any stabilizing agents.

    Abstract: A method of making ceramics is provided. The method comprises preparing a dispersion of a nano-material. A slurry of a ceramic matrix material is prepared. The nano-dispersion is mixed with the matrix slurry to form a nano-dispersion/slurry mixture. The nano-dispersion/slurry mixture is dried. The nano-dispersion/slurry mixture is pressed into a final manufacture comprising a granular structure including the nano-material bonded within and uniformly distributed throughout the granular structure. The manufacture comprises an increased fracture toughness compared with a conventional manufacture produced without bonding the nano-material within the granular structure. The nano-material has a size on the order of tens of nanometers. The matrix material has a size on the order of several micrometers. Five percent of the nano-dispersion/slurry mixture comprises the nano-material dispersion. Sintering is performed on the final form using a sintering process following the pressing step.
