  • Patent number: 8889097
    Abstract: An on-board hydride storage system and process are described. The system includes a slurry storage system that includes a slurry reactor and a variable concentration slurry. In one preferred configuration, the storage system stores a slurry containing a hydride storage material in a carrier fluid at a first concentration of hydride solids. The slurry reactor receives the slurry containing a second concentration of the hydride storage material and releases hydrogen as a fuel to hydrogen-power devices and vehicles.

  • Publication number: 20140283574
    Abstract: An extrusion apparatus and process are disclosed that produce high-performance extrusion structures. The extrusion apparatus includes a shear tool that applies a rotational shear force and an axial extrusion force to the face of a billet material that plasticizes the billet material. Plasticized material is extruded through an extrusion die along the length of the inner bore of the shear tool which yields hollow and solid extrusion structures. The process refines the microstructures of the extrusion structures and extrusion materials.

  • Patent number: 6692704
    Abstract: A non-thermal plasma (NTP) reactor structural conductor element includes a base conductor support and a high dielectric constant (“high k”) barrier layer supported by and substantially surrounding the base conductor support to form a structural conductor NTP reactor element. The structural conductor element may comprise a variety of shapes such as plates, sheets, half-box, I shapes, C shapes, or comb shapes, among others. In one embodiment, the dielectric barrier layer includes a coating applied to the base conductor support. In another embodiment, the dielectric barrier layer includes a high k film laminated to the base conductor support. In yet another embodiment, the base conductor support integrally forms the dielectric barrier layer via conversion of surfaces of the base conductor using electrochemical, thermal or chemical means to form the dielectric barrier layer.
