Abstract: A method for preparing resin-impregnated graphite articles, including providing a sheet of compressed particles of exfoliated graphite having two major surfaces; impregnating the sheet with a first resin system to form a resin-impregnated sheet; surface treating the resin-impregnated sheet to form at least one structure on at least one of the major surfaces of the sheet to form a surface treated sheet; and treating the sheet with a second resin system.

Abstract: One use for irradiated graphite after remediation processing is to recycle it into a new graphite artifact. Examples of such artifacts include an electrode to be used for vitrification of radionucleotides, graphite or carbon articles for uranium processing, a moderator for a HTGR, in particularly a Gen IV HTGR, other types of graphite products for nuclear facilities, charcoal filters, silicon carbide applications, etc. Such graphite artifacts can be formed with up to 20 pph of carbon black, the carbon black is formed from vitrified irradiated graphite. Optionally the graphite artifact may be formed from up to 75 pph of pitch.

Abstract: A reduced puffing needle coke is formed, which includes a lesser amount of nitrogen within the coke so that carbon articles produced from such coke experience minimal expansion upon heating to graphitization temperatures.

Abstract: A battery pack includes a plurality of cell assemblies each of which include one or more prismatic batteries. A frame has legs sized and configured to be positioned around the prismatic batteries. At least one leg includes a rear face, curved outer edge and a side face. A thermal transfer sheet is made from a sheet of a compressed mass of exfoliated graphite particles. Each thermal transfer sheet is positioned to contact the major surface of the at least one prismatic battery and is bent over the curved outer edge. At least a portion of each thermal transfer sheet is secured between a heat sink and the side face.

A substrate carries the electronic device and includes a face. The electronic component is secured to the substrate with the thermal interface sheet positioned between the mating surface and the face. The mating surface is relatively less flat than the face and the mating surface is relatively smoother than the face.

Abstract: A high coking value pitch prepared from coal tar distillate and has a low softening point and a high carbon value while containing substantially no quinoline insolubles is disclosed. The pitch can be used as an impregnant or binder for producing carbon and graphite articles.

Abstract: A battery pack thermal management assembly draws heat from prismatic batteries having opposed major surfaces and arranged in a stacked configuration inside a housing. The thermal management assembly includes a plurality of thermal transfer sheets made from sheets of a compressed mass of exfoliated graphite particles. Each thermal transfer sheet is positioned to contact the major surface of at least one of the prismatic batteries. A cover plate has a top face and a bottom face and includes a plurality of apertures through which the plurality of thermal transfer sheets extend. The apertures include at least one curved sidewall and the thermal transfer sheets are bent over the curved sidewall. At least a portion of each of the thermal transfer sheets is secured between a heat sink and the top face.

Abstract: A method of forming a graphitic carbon body employs compression and resistance heating of a stock blend of a carbon material and a binder material. During molding of the body, resistance heating is accompanied by application of mechanical pressure to increase the density and carbonization of the resulting preform body. The preform can then be subjected to a graphitization temperature to form a graphite article.

Abstract: A furnace insulation assembly includes a main body having a generally U-shaped cross-section. The main body includes a pair of side walls. A pair of end plates are secured to opposed ends of the main body. The end plates and the main body form an interior chamber. The end plates and side walls are made of a thermal insulation material formed from carbon fibers, said carbon fibers in each end plate and side wall are oriented against-grain direction points inwardly toward the interior chamber.

Abstract: An improved method of operating an arc furnace is provided. The sidewall of the furnace includes a refractory lining. A charge of scrap metal is added to the furnace. The charge is melted and a slag layer is formed on the top of the melting charge. The furnace is tapped at the bottom to remove a portion of the melted charge. After tapping the furnace, the slag is splashed onto the sidewall to thereby coat the sidewall with a frozen slag layer.

Abstract: A reduced puffing needle coke is formed from decant oil, which includes a lesser amount of nitrogen within the coke so that carbon articles produced from such coke experience minimal expansion upon heating to graphitization temperatures.

Abstract: A luminaire includes two housing halves, movable relative to each other between an open and closed configuration. The bottom housing half includes disposed therein a substrate which itself carries at least one LED which transmits light through a window in the bottom housing half. A thermal bridge made of at least one layer of anisotropic thermally conductive graphite is in thermal contact with the substrate and the top housing half when the housing is in the closed configuration, but its disengaged from either the substrate or top housing half when the housing is in the open configuration.

Abstract: A light bulb (10) including an outer housing (12) shaped like a standard Edison light bulb. The interior of the bulb includes a circuit board (24) and one or more LEDs (26). A heat sink (30) is provided inside the bulb housing that draws thermal energy away from the LEDs using graphite based materials.

Abstract: A graphite electrode exhibits oxidation resistance by modifying the outer radial surface characteristics. The outer radial surface may be modified by providing a textured portion which improves water flow while minimizing water absorbtion. Alternately, a layer of flexible graphite or plurality of particles of exfoliated graphite may be disposed on the outer radial surface of the electrode body.
