  • Publication number: 20110206928
    Abstract: A reinforced fiber is disclosed including a base material composed of a reinforcement ply having interstitial spaces; and a bacterial cellulose interwoven over the reinforcement ply and throughout the interstitial spaces. The reinforced fiber is obtained by (a) providing a base material composed of a reinforcement ply having interstitial spaces; and (b) contacting the base material with an effective bacteria in a microbial fermentation synthesis process for a time period sufficient to grow bacterial cellulose throughout the interstitial spaces of the reinforcement ply thereby providing a reinforced fiber interwoven with the bacterial cellulose. Also disclosed reinforced silicon carbide-containing nanofibers and processes for their preparation.

  • Patent number: 6607414
    Abstract: A novel technique utilizing the precision of printed circuit board design and the physical versatility of thin, flexible substrates is disclosed to produce a new type of ion reflector. A precisely defined series of thin conductive strips (traces) are etched onto a flat, flexible circuit board substrate. Preferably, the thin conductive strips are further apart at one end of the substrate and get increasingly closer towards the other end of the substrate. The flexible substrate is then rolled into a tube to form the reflector body, with the conductive strips forming the rings of the ion reflector. The spacing between the traces, and hence the ring spacing, can be readily varied by adjusting the conductor pattern on the substrate sheet during the etching process. By adjusting the spacing between the rings, the characteristics of the field created by the reflectron can be easily customized to the needs of the user.

  • Patent number: 6418962
    Abstract: A compressed gas vehicle fuel storage system comprised of a plurality of compressed gas pressure cells supported by shock-absorbing bumpers positioned within a low cost, shape-conforming container. The container is dimensioned relative to the compressed gas pressure cells whereby a radial air gap surrounds each compressed gas pressure cell. The radial air gap allows pressure-induced expansion of the pressure cells without resulting in the application of pressure to adjacent pressure cells or physical pressure to the container. The pressure cells are interconnected by a gas control assembly including a thermally activated pressure relief device, a manual safety shut-off valve, and means for connecting the fuel storage system to a vehicle power source and a refueling adapter. The gas control assembly is enclosed by a protective cover attached to the container. The system is attached to the vehicle with straps to enable the chassis to deform as intended in a high-speed collision.
