Abstract: An apparatus comprises a display item having a substantially rigid support piece and a non-magnetic adherence layer comprised of polyvinyl chloride foam configured to adhere to non-ferromagnetic surfaces. Additionally, the apparatus includes an adhesive layer applied between the adherence layer and the support piece of the display item. The adhesive layer is operable to attach the adherence layer to the support piece so that the display item may be selectively displayed on a non-ferromagnetic surface.

Abstract: A liquid retaining pressure relief valve for electrochemical battery cells is provided including a pressure regulator and a membrane vent that are mounted to the top and bottom ends of a threaded valve housing or plug. The valve housing or plug screws into the cell cover from the outside of the cell such that the membrane vent is internal to the cell. The membrane vent includes a thin gas permeable liquid repellant membrane that is molded into the body of the vent. The membrane is preferably composed of an expanded polytetraflouroethylene (ePTFE) polymer.
