| 20090006367 | SEARCH-BASED FILTERING FOR PROPERTY GRIDS - Technologies for search-based filtering of a property grid. Such filtering allows a user to enter a search term into an easily recognized search text box, or apply a user or pre-defined term to a property grid, thus reducing the set of properties visible so that the user has a smaller list to search to find the one on which they desire to operate. The search term is typically applied to all properties shown in the property grid. Elements that match the search term are made visible in an updated property grid while those that do not match are not presented. Also, the search term may be applied to more than just the name of the property. It may be applied to a category within which the property appears, the type of the property, or any of a number of attributes or tags that may be applied to the property. | 01-01-2009 |

| 20080282457 | CANISTER FLUSH VALVE - A canister type flush valve has an upright cup-shaped hollow float working under buoyancy forces without a captured air volume that controls the valve during a flush cycle. Hooded bleed openings at a bottom wall of the float can be sized and numbered to selectively control the closuring timing of the valve. Baffles of the hood bleed openings redirect water bleeding into the float to prevent the water from spraying up against the top of the tank. The geometry of a seal retaining groove is designed to reduce leakage at the float/seal interface. For example, the groove has an annular wall with a compound profile forming a non-cylindrical, preferably serpentine, seal contact area. The seal is backed by a slotted flange located just above the retaining groove. | 11-20-2008 |
