Abstract: A cross-linked microporous polysulfone or polysulfone copolymer battery electrode separator membrane are described. Such membranes, which would otherwise be soluble above a particular, generally high temperature in selected battery electrolyte systems, once at least in part cross-linked, swell in the electrolyte at the particular higher temperature instead of dissolving. When the membrane separators are restrained between solid electrodes in a battery, the separator cannot increase in bulk volume, and the swelling occurs within the pores with the pore volume decreasing from its original bulk volume. The drop in pore volume causes the battery current density to drop, thereby reducing the heat generation within the hot area of the battery. This process provides a measure of safety against overheating and fires, and the battery is capable of continued usage if the overheating is localized.

Abstract: An inner drive for a magnetic drive pump includes a magnet supported on a yoke. The inner drive is driven about an axis to pump a corrosive process fluid. The magnet and yoke are fully encapsulated during the molding process to completely surround the magnet and yoke in a protective plastic shell. A sleeve is arranged radially outwardly of the magnet to provide further protection. Backing rings are arranged on either side of the magnet. A bonding material joins the plastic shell to the backing rings and sleeve to prevent a space from forming beneath the plastic shell that would become filled with the process fluid once it has permeated the plastic shell. A protective coating is arranged on at least a portion of the magnet to further insulate the magnet from the process fluid.

Abstract: A composite ice blade may have a metal ice edge bonded to a metal foil. The metal foil may be bonded to a plastic core to form a composite sandwich having a center plastic core and metal sides. The ice edge may be bonded to the foil by welding or brazing, then formed into shape to accept the plastic core. The plastic core may be injection molded directly into the formed metal structure, or bonded to the metal components in a secondary operation.

Abstract: A battery separator may be formed with hard spacers made from ceramic and other high temperature materials. The spacers may be incorporated into a microporous membrane so that the microporous matrix may capture and hold the spacers. The spacers may be solid or hollow glass beads that are in the range of 30% to 100% of the thickness of the separator, and may comprise less than 10 weight percent. The resulting membrane may be largely microporous, and the separators may help battery electrodes to remain physically separated, even after internal temperatures exceed the melt temperature of the separator.

Abstract: A microporous polymer used as a battery separator may be formed with hard, insoluble dielectric spacer materials in fibrous or particulate form. The spacer materials may form a barrier when the battery separator may melt or be crushed during an over-temperature event, possibly preventing a fire. The spacer materials may be located within the polymer matrix and may be added to a solution used to form the microporous polymer.
