20150328815 | System and Method For Extruding Parts Having Microstructures - This invention is directed to a microstructured filament that can be used to make fibers having an extruded filament having pre-cooled microfeatures in a radial spiral arrangement about a bore though the filament wherein the microfeature has a width in the range of 25 μm to 40 μm and height in the range of 90 μm to 100 μm; and, the filament having a post-cooled state having post-cooled microfeatures having physical dimensions smaller than that of the pre-cooled microfeatures. The filament can include microfeatures having a width in the range of 400 nm to 4 μm and height in the range of 400 nm to 4 μm. The filament and fiber can include physical characteristics selected from the group consisting of: hydrophobicity, self-cleaning, increased hydro-dynamic drag coefficients, decreased or increased aerodynamic drag coefficients, increased friction, reduced friction, optical effects, increased adhesion, decreased adhesion, oleophobicity, tactile effects, anti-blocking and any combination of these. | 11-19-2015 |

20150307773 | Proppant For Fracking Fluid - This invention is a fracturing component and method having a fluid and a plurality of three dimensional structures mixed in the fluid wherein each structure has a longitudinal axis, center of mass and center of pressure wherein the center of mass and the center of pressure do not align in a stable manner causing the structure to flutter in the fluid to reduce the structure from settling out of the fluid when injected into a fissure. Each three dimensional structure can include a first end of the structure having a first plane having an angle of incident θ | 10-29-2015 |

20120067484 | Sacrificial Layer to Relieve Pinch Flashing in Molding Operations - A method to reduce or eliminate pinch flashing in mold operations by applying a thin coating of a hydrocarbon wax to the outside surface of an uncured rubber article or on the sidewall or shoulder of a green tire at a location(s) where segments of the mold close on each other and on the rubber article or tire during cure. The hydrocarbon wax has a melting point from about 60 degrees to about 80 degrees Celsius, and is compatible with the composition of the rubber. The hydrocarbon wax acts as a sacrificial layer and is scraped up by the mold parts instead of the rubber when the mold segments close. | 03-22-2012 |
