Abstract: A system for neutralizing prescription drugs, narcotics and other harmful substances, including a staging area for an initial collection and sorting of prescription drugs, narcotics and other harmful substances to be neutralized, a containment chamber assembly operatively connected to the staging area for granulating the prescription drugs, narcotics and other harmful substances, a waste grinder/vacuum assembly operatively connected to the containment chamber for destroying any packaging that contained the prescription drugs, narcotics and other harmful substances, and a neutralizing assembly operatively connected to the containment chamber for neutralizing the granulated prescription drugs, narcotics and other harmful substances, with a neutralizing agent.

Abstract: A method for forming a ceramic matrix composite bearing includes preparing a layup slurry from a mixture of water, pre-ceramic polymer and refractory filler. The method further includes forming a concentric stack of slurry-impregnated fabric sleeve layers over a rod-shaped inner mold and applying an outer mold to form a mold assembly. The method also includes heating the mold assembly to form a tubular green body and rough cutting the green body to bearing length. In addition, the method includes heat-treating the bearing and performing a polymer infiltration and pyrolysis treatment. The method further includes conducting dimensional stability treatment processes on the bearing and final grinding and machining to meet pre-determined specifications.

Abstract: A handguard comprising a plurality of layers of composite material. At least one of the layers is a ceramic matrix composite and at least one of the layers, and preferably the outer later, is a carbon fiber reinforced composite. In addition, the outermost layer is preferably a woven fabric carbon fiber reinforced composite. In one embodiment, one or more ceramic matrix composite layers is sandwiched between layers of carbon fiber reinforced composite. In another embodiment, an innermost layer is a ceramic matrix composite and the outermost layer is a carbon fiber reinforced composite.

Abstract: The present application teaches fire-resistant structures and methods for wellhead outlets, and methods of using same. In one embodiment, the fire-resistant structure includes a plurality of spacing assemblies (32a-f) that space a plurality of fire-resistant panels (42, 44, 46, 48, 49, 50, 53, 55) away from the exterior surface of a wellhead outlet (1), such that a space or volume is created between the fire-resistant panels (42, 44, 46, 48, 49, 50, 53, 55) and the exterior surface of the wellhead outlet (1).

Abstract: The present application teaches a color-changing component for a firearm and methods for constructing same. In some embodiments the component is a magazine comprising a photochromatic body that changes color and/or opacity based on the introduction or removal of light to the body. In alternate embodiments the component is any type of weapon-mounted aiming or sight-aiding device for which it would be desirable to reduce the risk of reflective glare or glint.
