Abstract: Flexible ceramic composite materials that include a polymer and silica aerogel disposed within the polymer are disclosed. The materials have extremely low thermal conductivity and excellent thermal stability and can be used to form seals, gaskets, and insulation for a variety of applications.

Abstract: An optically clear biofouling resistant coating compositions specially formulated for very high light transmission and more particularly coating compositions which can be applied to marine instruments and sensors. The compositions provide a biofouling resistant coating on the surface of the marine instruments and sensors which prevents underwater organisms from adhering and growing on the surfaces of the structures over a long period of time.

Abstract: Sealing devices are provided as configured for use with cathode devices of an electrolytic cell for production of aluminum. In particular, the seals are specifically configured to provide an outlet seal for the cathode bars. The sealing devices are made of a material that is elastic, gas-proof, and heat-proof, and can create a hermetic seal around the cathode bar in such a way as to be able to move synchronously or asynchronously with the movement of the cathode bar as it undergoes thermally induced movement during aluminum production.

Abstract: The cathode collector bar end portion extending through a window in a sidewall of an electrolytic cell for refining aluminum is snugly received in a central opening of a seal assembly. Such seal assembly maintains a hermetic seal preventing ingress of air through the sidewall window while permitting longitudinal (horizontal) movement of the collector bar and also movement in a vertical plane (side to side, or up and down, or diagonally) which can be caused by changing heat conditions inside the cell.

Abstract: An anti-biofouling seismic streamer casing (100,100?) is provided that is formed by a flexible tubing (110) coated with a layer of a two-part heat cured silicone elastomer (120). The seismic streamer casing (100, 100?) is formed by a method that includes steps of providing a flexible tubing (200) and pre-treating the outer surface of the tubing (210). Two parts of a two-part silicone elastomer are then mixed together (220). The method also includes coating the mixed two-part silicone elastomer on the flexible tubing (230), and heating the flexible tubing to cure the coating (240).
