    Abstract: A prismatic battery module includes a prismatic battery case having a plurality of prismatic cell cases connected to one another through separation walls, a planar electroconductive connector forming part of the separation wall between the cell cases, an electrode plate group arranged in each cell case, and an electrolyte placed in each cell case. Lead portions of positive electrode plates and negative electrode plates of the electrode plate group are directly connected to the electroconductive connector. The prismatic battery module requires fewer connection points and provides shorter electrical communication paths, thereby reducing internal resistance.

  • Publication number: 20030077509
    Abstract: An economical method for manufacturing an electrode assembly of virtually any shape to fit into a similarly shaped casing without compromising volumetric efficiency is described. This is accomplished by providing an electrode assembly of multiplate anode and cathode plates that substantially match the internal shape of the casing. That way, no matter what shape the device being powered by the cell dictates the electrode assembly assumes, as little internal volume as possible is left unoccupied by electrode active materials.

    Abstract: The present invention relates to a material and a method for treating of photographic effluents in order to eliminate micro-organisms and pollutant by-products so as to control bacterial growth and thereby obtain effluents that comply with regulatory requirements. The method for preparing an oxidizing material according to the invention comprises the dispersion in colloidal form of a metal or metal compound in an aqueous solution of an inorganic aluminosilicate polymer, said aluminosilicate being able to form an inorganic gel, and said metal or metal compound being able to cause the oxidation of oxidizable products and (or) micro-organisms to be eliminated, followed by the addition of a base to cause said aluminosilicate to gel. The metal is preferably silver in a powder form that is able to form a colloid when it is dispersed. The oxidizing material of the invention is efficient especially for the treatment of photographic baths, in particular wash baths placed after the fixing step.

  • Publication number: 20030077553
    Abstract: A fluteless endodontic file is provided, formed from a tapered shaft of material having a prismatic shape generally defined by three or more side surfaces and three or more interposed corners. A plurality of notches are cut into one or more corners defining cutting surfaces, points and/or edges. The notched cutting surfaces are formed such that the file, when rotated and/or reciprocated within a root canal, effectively cuts/debrides hard tissue (known in the art as dentin) as well as soft tissue, thus, forming an optimal canal shape. The cutting surfaces are also preferably formed at an angle to the centerline of the instrument to provide optimal cutting efficiency and material removal. The fluteless file design exhibits increased efficacy, with less tendency to bind and break within the root canal and also significantly reduces manufacturing and capital equipment costs.

    Abstract: A keyboard guide is disclosed herein having a substantially rectangular frame. The frame has a front and back wall interconnected by two side walls. The guide also includes at least one divider, coupled between the front and back wall, having a top edge leaning toward the side wall that is closest thereto, to form an angle with respect to a vertical orientation. The keyboard guide may also include at least one indicator, positioned on the divider, to indicate a key location. In one embodiment, the indicator is a bump on a side of the divider. The keyboard guide may also include a central divider, coupled between the front and back walls, having a substantially vertical orientation along a top and bottom edge. The guide may also include right-side and left-side dividers, on opposite sides of the central divider respectively.
