| 20090069175 | Nanostructured anode PT-RU electrocatalysts for direct methanol fuel cells - An aerosol-assisted method for synthesis of nanostructured metallic electrocatalysts and the electrocatalysts formed thereby. The electrocatalyst may be formed from metals such as, but not limited to, platinum, platinum group metals, and binary and tertiary compositions thereof such as, for example, platinum-ruthenium and platinum-tin. The resulting unsupported electrocatalyst is homogenous and highly disperse. | 03-12-2009 |

| 20110200432 | REVERSE FLOW TOLERANT SPRING ACTIVATED BRUSH SEAL - A reverse flow tolerant brush seal arrangement for restricting the transfer of a pressurized fluid between a first and a second chamber along a moving shaft. Opposing backing plates are provided to stiffen brush bristle alignment on the moving shaft. Differential pressure between the chambers is aided by spring biasing to seat axial movement of a sliding brush seal against one of the opposing backing plates for stiffening to maintain a design clearance with a shaft being sealed. | 08-18-2011 |
