    Abstract: An improved battery plate (40) and a method of making for an electric storage battery (10). The battery plate comprises a plurality of metallic fibers (50, 52) of a single or plural diameters (d, D) randomly oriented and sintered to provide a conductive battery plate with a multiplicity of pores defined therein (60). The metallic fibers are formed by cladding and drawing a plurality of metallic wires to provide a fiber tow. The fiber tow is severed and the cladding is removed to form metallic fibers. The metallic fibers are arranged into a web and sintered to form a battery plate.

    Abstract: Methods and apparatus for gas phase sulfonation of preformed polymeric membranes are provided in accordance with the present invention. The invention enables conversion of a hydrophobic membrane that is capable of reaction with a gas phase sulfonation agent into a hydrophilic membrane. As will be understood, aromatic rings, amines, hydroxyl groups, and other reactive moieties in polymers are readily sulfonated when exposed to sulfur trioxide gas. Thus, in accordance with the present invention, a preformed polymer membrane that contains aromatic rings or other moieties that are capable of reaction with a gas phase sulfonation agent, is exposed to a gas phase sulfonation agent, such as sulfur trioxide, and the aromatic rings or other moieties of the polymer become sulfonated. The inclusion of sulfonate groups on such polymers, and the membranes formed therefrom, renders such polymers totally or partially hyrophilic. The invention also relates to polymeric membranes, including asymmetric sulfone polymer membranes sulfonated by the process of the invention, and to devices for carrying out the sulfonation method of the invention.

    Abstract: The present invention relates to a method for defining an area (4) of a layer on a porous substrate comprising compressing a volume of the substrate to produce a compressed region (8) which defines, or which in combination with an edge (7) of the substrate or of the layer defines, a boundary of the area and which substantially prevents the transport of material through or across its surface. The present invention also relates to an electrochemical sensing device comprising: a porous substrate; and an electrode (1) on one side of the substrate; wherein a region of the substrate is compressed to an extent which forms a barrier to migration of electrolyte within the substrate, the compressed region defining, or in combination with an edge of the substrate or the electrode defining, a zone on the electrode of predetermined area.

    Abstract: In critical filtration applications, filter cartridges (200) are employed to replace ion exchange resin precoat filters to minimize the waste produced. The filter cartridges (200) which are housed in a multiple cartridge filter housing (300) with an inlet (320), an internal baffle plate (330) which defines an upper chamber (340) and a lower chamber (350), are backwashed with all gas via a gas inlet (410) and the liquid in the filter housing (300) provides an active scouring effect as a result of the high levels of turbulence produced. The baffle plate (330) is provided with ports (360) to receive the cartridges (200). Chamber (350) is provided with a filtrate outlet (380). The liquid, with entrained debris from the filter, is minimized in volume.
