Filed:

Aug 16, 2007

Appl. No.:

11/893529

Inventors:

Gary J. DeAngelis - Spencerport NY, US
David J. Ranelli - West Henrietta NY, US
Amanda M. Weiss - Livonia NY, US

International Classification:

F16J 15/00

US Classification:

277500

Abstract:

A wiper seal subassembly for disposal in rotor vanes or stator lobes of a vane-type camshaft phaser comprises a backing spring and a sealing element. The sealing element includes spring retention features that loosely retain the backing spring and that are integrally molded into the sealing element. The spring retention features include undercut retention features, such as an overhanging edge, that prevent the backing spring from vertically detaching from the sealing element. The spring retention features further include sidewall tabs that prevent the backing spring from horizontally detaching from the sealing element. The sealing element is formed from a plastic composite material during an injection molding process using a simple injection mold tooling design. The single-piece wiper seal subassembly is provided at the tip of each rotor vane and/or stator lobe of a vane-type camshaft phaser for varying the timing of combustion valves in an internal combustion engine.

International Classification:

H01M 8/18

US Classification:

429 20

Abstract:

A catalytic reformer assembly including a reactor comprising a plurality of parallel tubes arranged within a tubular housing. A metal substrate, formed preferably as a metal foam lattice, is brazed to the tubes on both their inside and outside surfaces. A catalytic washcoat is applied to the metal substrate within the tubes, defining thereby the tubes as individual catalytic reforming reactors. Endothermic reforming reactions within the tubes are supported by heat from hot combustor exhaust flowing around the tubes in contact with the augmenting heat transfer metal substrates outside the tubes. Radial temperature gradients are small because of excellent heat transfer across the tube walls, resulting in excellent mechanical stability of the washcoat on the metal substrate. Preferably, the tubes are formed of Inconel 625 and the metal substrate is formed of Fecralloy, a high temperature alloy having excellent thermal conductivity and oxidation resistance.

International Classification:

H01M 8/18

US Classification:

429 20

Abstract:

A planar endothermic reformer assembly comprising only a few macrochannels rather than many microchannels as in the prior art. The macrochannels are arranged alternately in a stack for reforming and hot gas flow in a cross-flow reformer/heat exchanger. The assembly includes four manifolds. An external combustor supplies heat to the hot gas macrochannels in the reformer/heat exchanger stack for endothermic reforming, resulting in low temperature gradients in the reforming macrochannels. The macrochannels, having no dimension less than 2.0 mm, contain metal substrates for heat transfer as well as for support for the catalytic washcoat and may comprise packs of corrugated sheet metal such as Haynes or Inconell; packs of wire mesh; metallic foam made of Fecralloy, Haynes, Inconel, or higher conductivity material; or stacks of metallic felt material. The metallic substrates are brazed into the reforming channels and the hot flow channels to ensure maximum heat transfer for highest reforming efficiencies.

Abstract:

A system comprising a cylindrical housing containing a sorbent cartridge selective of one or more gases in a gaseous mixture. End caps on opposite ends of the housing seal to the ends of the cartridge and direct the flow of gas mixture through a portion of the cartridge. The first end cap has entrance and exit ports for the gas mixture and for a purging gas for cartridge regeneration. The second end cap includes a compartment to receive and return the gas mixture to the first cap exit port. The purging gas follows a similar pathway via the remaining portion of the cartridge. The cartridge is rotatable within the housing; thus, the exhausted portion of the medium may be rotated into position for regeneration while a regenerated portion of the medium is rotated into position for re-use, thus providing continuous adsorption from the gas mixture.
