  • Patent number: 9624388
    Abstract: Described is a thixotropic para-aramid gel that includes a polymer resin, an alkali-soluble anionic thickener, an adhesion promoter, and para-aramid pulp fibers. The polymer resin includes at least one of an acrylate copolymer and a styrene-acrylate copolymer. Also described is a method of producing the para-aramid gel for plaster reinforcement. The method includes mixing the polymer resin, the alkali-soluble anionic thickener, and the adhesion promoter to create a thixotropic gel, and then spinning para-aramid pulp fibers into the thixotropic gel using a high shear mixer. A method of reinforcing a plaster ceiling is also described. The method includes inserting a plurality of fasteners into a visible surface of the ceiling, leaving a portion of each fastener exposed at or above the visible surface, and applying a layer of the para-aramid-reinforced thixotropic gel to the visible surface and encapsulating the portion of each fastener within the layer.

  • Patent number: 8684876
    Abstract: A power transmitting component includes a housing having an interior cavity with a sump, a lubricant disposed in the sump, and a component mounted in the housing assembly for rotation about a first axis. The component rotates through the lubricant in the sump to generate a stream of lubricant that is slung from the component as it rotates at a speed in excess of a predetermined speed. The housing includes a deflector that extends into the interior cavity and has a first face having an impingement portion and a first edge adjacent the impingement portion. The impingement portion extends into the stream and deflects a portion of the stream towards the first edge. The first edge disperses the portion of the stream toward selected areas in the interior cavity.
