Abstract: A multi-cell battery constructed of a plurality of frames of insulating material each frame having a number of active battery material areas arranged side by side with a division portion between each material area, the frames being arranged side by side in a direction normal to the plane of the frame with the division portions secured in sealed relation to form partitions between adjacent cells of the battery. The active battery material in respective areas being selected so that adjacent areas in each frame are of opposite polarity and adjacent areas in adjoining frames are of opposite polarity. A barrier frame interposed between and secured to two frames in the assembly forming a chemical and electrical barrier between the active battery material in frames on opposite sides of the barrier member so that the assembly of frames forms two batteries of equal nominal voltage.
Abstract: A multi-cell battery comprises a plurality of frames each divided into a number of side by side active paste support areas. The frames are assembled and secured together in a stacked formation so that the perimeter portions of the frames form the top, bottom and two opposite sides of the battery, and the divisions in the frames form cell partitions.Each frame is pasted with active material to form plates with adjacent plates in each frame being of opposite polarity and adjacent plates in each frame being of opposite polarity and adjacent plates in adjoining frames also being of opposite polarity. Electrolyte-porous separator material is provided between adjacent plates in adjoining frames.
Abstract: A method of producing steel reinforced conveyor belting wherein the steel reinforcing cords are located in grooves formed between the mating faces of two layers of P.V.C. based material. The faces of the grooves are coated with an adhesive having a P.V.C. base including an epoxy resin and curing agent and the steel cords are adhered to the layers of P.V.C. by curing the assembly of cords and cover layers under heat and pressure.
