Abstract: A separator for an energy storage cell that is provided by a microporous web that includes an irreversible porosity-controlling agent a method for changing an operating characteristic of an energy storage cell.

Abstract: A separator for an energy storage cell having a microporous matrix including a reversible porosity-controlling agent. The porosity-controlling agent is selected from the group consisting of agents that change size as a function of temperature, agents that change size as a function of electrolyte concentration, and agents that change size as a function of temperature and electrolyte concentration to provide a change in an overall porosity of the separator.

Abstract: A method and apparatus for providing three-dimensional images of one or more objects. The apparatus includes a base substrate, an image layer on said substrate, and a lenticular material superposed on the image layer. The image layer is provided by an imaging tool configured for depositing pixels on the substrate from contour corrected pixel data such that the deposited pixels have a structural contour relationship to the one or more objects. The imaging tool manipulates the pixel data to be compatible with the substrate and lenticular material. The method provides substantially improved three-dimensional images and devices containing improved three-dimensional images.

Abstract: A method for making an essentially natural rubber latex-free elastic compression bandage. The method includes providing a homogeneous mixture containing from about 20 to about 90 parts by weight synthetic natural rubber, from about 10 to about 80 parts by weight secondary elastomeric compound, fillers and processing aids. The mixture is fed to an extruder to provide an extruded web. The extruded web is calendered to provide a calendered web, and the calendered web is electron beam cured to provide an elastic web having a reduced bio-burden. The reduced bio-burden of the web enables production of bandages without prolonged sterilization techniques.

Abstract: The invention provides a separator for an energy cell which includes a compressible web made from a blend of elastomeric material and cross-linking agent, the elastomeric material being selected from natural rubber and a mixture of natural rubber and synthetic rubber. The blend is expanded, cast and cured to form a web containing micropores so that the resulting web comprises an open cell structure having a thickness ranging from about 40 to about 150 mils, an alcohol porosity of from about 45 to about 90% and a compressibility of at least about 20%. Lead-acid battery cells containing the separators have the advantage of significantly improved life as a result of the improved strength and resiliency of the separator.

Abstract: An improved separator for an energy storage cell is described which is made of a porous polyolefin matrix and contains from about 0.5 to about 30 dry weight percent particulate filler. The particulate filler is a cured, porous rubber material which enhances the electrochemical properties of the separator as compared to conventional polyolefin separators.
