Abstract: A vehicle has a body; a side door, mounted on the body, at a side of the vehicle; and a back door, mounted on the body, at a back of the vehicle. The side door and the back door are mounted on the body such that a rear edge of the side door and an outboard edge of the back door are adjacent to each other when the side door and the back door are closed. The invention may also include a seal to seal a gap between the rear edge of the side door and the outboard edge of the back door. The invention may further include a back pillar outer panel recessed from an outer surface of the vehicle. The seal can be mounted on the back pillar outer panel to seal a gap between the rear edge of the side door and the outboard edge of the back door.

Abstract: A filter media system, which is capable of operating in the microfiltration regime, offers: low cost, durability, high temperature and chemical resistance, no particulation, mechanical strength, separation efficiency, and biocompatibility. A filter media system is comprised of a carbon or ceramic composite substrate which contains a carbon or ceramic matrix reinforced with carbon or ceramic fibers. The composite has an array of carbon or ceramic fiber whiskers grown onto its surface or in its bulk. A process is provided for manufacturing the filter media system wherein a carbon fiber is disposed in a matrix deposited by a CVI or LPI process, at temperatures of about 900 to about 1200° C. to achieve a weight gain of about 10 to 200% (the ceramic matrix is deposited by a CVI process from an aqueous slurry or by use of a preceramic polymer). This composite is treated with an aqueous solution of metal catalyst salt and is then heated in hydrogen at elevated temperatures to reduce the metal salt to metal.

Abstract: The present invention provides a carbon-carbon (C/C) composite valve structure useful for high temperature internal combustion engines comprising (a) a carbon-carbon (C/C) composite valve stem having a flared end and a non-flared end opposite the flared end; and (b) a carbon-carbon (C/C) composite valve head applied onto the flared end of the valve stem, wherein at least one of the carbon-carbon (C/C) composite valve stem and head is coated with a high temperature resistant coating.
