Abstract: A reclosable elastomeric fastener and method for sealing storage and serving containers using same. The fastener consists of two complementary elastomeric profiles, having male and female interlocking elements, which extend around the periphery of the lid and container components of a storage receptacle. The reclosable fastener forms a water-resistant seal when the male and female elements of the complementary profiles are mutually occluded.

Abstract: A fluid management system for use in water electrolysis systems for filtering the system water and recombining hydrogen and oxygen. The fluid management system includes a phase separation tank having a filter containing a catalyzed ion exchange resin. Hydrogen/water mixture and an oxygen/water mixture are introduced into the resin where hydrogen is recombined with oxygen to produce recovered water. Trace contaminant ions and particles are removed from the water by the ion exchange resin and the filter.

Abstract: A covering sheet for applying to a selected surface in substantially fitted, covering relation consists of a flexible sheet of predetermined size and thickness, having a rectangular grid of lines to provide rectilinear yield lines (lines of weakness) extending in a first direction and in a second direction at right angles to the first direction, to enable tearing by hand along selected ones to the grid lines as a tear in a first direction, the sheet having individual perforations extending completely through its thickness, and located at the points of intersection of the axes of the lines of weakness. The perforations facilitate changes in the direction of a tear at a selected point of intersection, to extend the tear in the second direction, to achieve a desired size of sheet.

Abstract: A cell frame is for use in an electrochemical cell wherein the cell frame includes fluid communicating inserts for providing process water to the electrochemical cell and to transport waste water and product from the cell. The cell frame comprises inserts positioned about the periphery of the frame to facilitate a uniform fluid field and membrane hydration. The cell frame further comprises a protective plate comprising sealing features and lip extensions to prevent fluid leakage and membrane damage.
