20120223004 | LIGHTWEIGHT PROTECTION ELEMENT AND FILTER OF THE MATTRESS TYPE - A lightweight protection element and filter of the mattress type comprises an external containment structure ( | 09-06-2012 |
20140027369 | ENHANCED SHAPE SUPPORT GRID - A support grid assembly for use in a vessel. The support grid assembly includes panels each including a first wall including a media-supporting screen and a second wall to be supported by the vessel wall inner surface. A manifold is coupled to the panels and is in hydraulic communication with vessel outlet. The manifold and the panels permit fluid to flow through the screen in each panel, through the panels, into the manifold, and through the manifold to the outlet of the vessel, as well as in the reverse direction. At least a portion of the first wall may slope downward toward the manifold, and at least a portion of the second wall may form a bottom surface that is curved to substantially conform to a curvature of the vessel wall inner surface. The panels may be arranged in a circular configuration extending radially from the manifold. | 01-30-2014 |
20140166567 | Filter System with Integral Media Retainer Seal - A filter system having a filter media retainer seal includes: at least one underdrain block having a top wall, a bottom wall, and a pair of side walls extending between the top wall and the bottom wall; a filter media retainer mounted onto the top wall of the at least one underdrain block; and at least one rib positioned between the underdrain block and the filter media retainer. The at least one rib forms a seal between the underdrain block and the filter media retainer, and prevents filter media from entering the underdrain block. The at least one rib can be monolithically formed to the at least one underdrain block. Alternatively, the at least one rib is monolithically formed to the filter media retainer. The rib is crushable and/or it bites into a surface on the adjoining part to reduce or eliminate the need for a separate sealant. | 06-19-2014 |
