    Abstract: A dry-charged lead acid storage battery has partially recharged electrodes which serve as a source of sulfate ions. An additional source of sulfate ions is also inside the battery container. In contrast to the partially or fully discharged electrodes in previous dry batteries, the electrodes of this invention are characterized by having active material in which the percent of lead sulfate in the active material at a specified distance from the center of the electrode grid decreases as the specified distance of the material from the grid decreases. These improved electrodes are produced by being fully charged, then completely discharged, then partially recharged, and then washed and dried.

    Abstract: THE TOPS OF RISERS EXTENDING UPWARD ON BOTH SIDES OF THE CONTAINER PARTITION FROM THE CONNECTING STRAPS ARE MELTED. THE MOLTEN RISER MATERIAL FLOWS INTO A HOLE IN THE PARTITION WHERE IT IS CHILLED TO PRODUCE AN INTERCELL CONNECTOR. MELTING IS DONE BY ANY SUITABLE ENERGY SOURCE, SUCH AS ELECTRICAL INDUCTION, HEAT CONDUCTION, PASSING A

    CURRENT THROUGH THE RISERS SUFFICIENT TO MELT THE RISER MATERIAL OR WITH A TORCH FLAME.

    Abstract: A ZINC ELECTRODE CONTAINING A LEAD SULFIDE ADDITIVE TO REDUCE GASSING AT THE ZINC ELECTRODE WHICH IS USED AS THE NEGATIVE ELECTRODE IN A HEAT STERILIZED SILVER-ZINC ALKALINE BATTERY. THE LEAD SULFIDE EFFECTIVELY REDUCES GASSING THE ZINC ELECTRODE WITHOUT ADVERSELY AFFECTING THE CAPACITY OF THE HEAT STERILIZED BATTERY, WHEREAS THE CONVENTIONAL MERCURIC OXIDE ADDITIVE REDUCES THE CAPACITY OF THE HEAT STERILIZED BATTERY. THE LEAD SULFIDE ADDITIVE MAY BE USED IN AMOUNTS RANGING FROM ABOUT 1 TO ABOUT 10% BY WEIGHT OF THE ACTIVE MATERIAL ADDITIVE MIXTURE.

    Abstract: AN AUTOMATIC, DUAL LEVEL, SATETY FILLING DEVICE IS INCORPORATED IN THE COVER OF A LEAD ACID BATTERY AND COMPRISES THREE OPENINGS IN THE COVER OVER EACH CELL AND ARE REFERRED TO AS THE WINTER HOLE, SUMMER HOLE, AND VENT HOLE RESPECTIVELY. A CLOSURE IS SLIDABLY ATTACHED TO THE COVER TO CLOSE THE WINTER AND SUMMER HOLES, OR THE SUMMER AND THE VENT HOLES, OR THE VNET HOLE ONLY. WHEN THE BATTERY NEEDS SERVICING, WATER OR ELECTROLYTIC SOLUTION IS POURED INTO THE UNCOVERED WINTER HOLE AND DEPENDING UPON

    WHETHER THE CLOSURE COVERS THE SUMMER HOLE AND THE VENT HOLE, OR THE VNET HOLE ONLY THE SOLUTION IN THE CELL RISES TO A "WINTER LEVEL" OR TO A "SUMMER LEVEL" RESPECTIVELY.

    Abstract: AN ELECTROCHEMICAL CELL HAVING A CYLINDRICAL METALLIC CONTAINER SEALED BY A HARD PLASTIC CLOSURE MADE FROM A COLD-FLOW RESISTANT PLASTIC, E.G. NYLON. THE PLASTIC CLOSURE IS RADIALLY COMPRESSED BY PUSHING IT THROUGH A REDUCING DIE AND INTO THE METALLIC CONTAINER. THE PLASTIC CLOSURE EXPANDS IN THE CONTAINER WITH SUCH FORCE THAT THE UPPER EDGE OF THE CONTAINER IS SLIGHTLY DEFORMED OUTWARDLY. THE UPPER EDGE OF THE CONTAINER IS CRIMPED OVER UPON THE TOP OF THE CLOSURE BY MEANS OF A CLOSING DIE WHICH AXIALLY COMPRESSES THE CLOSURE BETWEEN THE UPPER EDGE OF THE CONTAINER AND A BEAD ROLLED INTO THE CONTAINER. THE AXIAL COMPRESSION DEVELOPS AN AXIAL FORCE IN THE PLASTIC CLOSURE, INCREASES THE RADIAL FORCE EXERTED BY THE PLASTIC CLOSURE UPON THE CONTAINER, AND THE COMPRESSION OF THE UPPER EDGE OF THE CONTAINER UPON THE CLOSURE INCREASES THE SEALING SURFACE BY FORMING BOTH AN AXIAL AND RADIAL SEALING AREA.
