Abstract: Apparatus and method for injecting molten lead from a reservoir into a die mold cavity formed about an aperture in the wall of a plastic battery for casting lead-alloy battery terminal connectors. Batteries are positioned adjacent the molten lead reservoir of the apparatus and mold portions move together to hold the battery containers in a clamp-like action. Molten lead is die cast under pressure into the mold cavity in which a stainless steel threaded nut is positioned. The lead is forced through a heated chamber into a portion of the mold which may be water cooled. The mold is designed to allow venting of gases, thereby eliminating porosity; and the apparatus is designed to provide casting which is free of jagged projections in the sprue hole.

Abstract: A method for forming lead-acid storage battery separator envelopes from a continuous roll of separator material of the type having ribs thereon. The method comprises withdrawing the separator material from the roll and clamping the withdrawn separator material along the length thereof to crush and deform the separator material ribs and produce two creases across the width thereof. The creases are spaced from each other approximately the thickness of a pasted battery plate. The clamping is released and the edge of a plate narrower in width than the separator material is introduced into contact with the separator material at the crushed and deformed portion thereof between the spaced creases. Thereafter the withdrawn separator material is folded along the length of the plate, so that the material overlaps the edges of said plate. Finally, the overlapped edges are sealed to each other.

Abstract: An apparatus and method for the sequential testing of series connected lead-acid storage batteries for short circuits between plates of opposite polarity within a cell and for electrical continuity between cells of said battery is disclosed. The apparatus comprises power and control circuitry working in conjunction with a terminal block containing a plurality of pins which are connected to the intercell lugs on the positive and negative straps which when welded together form the intercell connections within the battery. Within this block, the pins are partially wired together so that if there is complete continuity of the intercell welds a continuous electrical circuit is formed. Midway in the electrical wiring is a blocking diode which acts to permit the passage of a DC test current in only one direction. If a positive polarity voltage is impressed on the cathode side of the diode, current will only flow if there is a short circuit between plates of opposite polarity within the cell.
