Abstract: Electric accumulator battery, which comprises a receptacle (1) with cover, of a size which fits in the compartment traditionally reserved for this purpose in a motor vehicle. This receptacle is subdivided internally into a series of cells (2) that are distributed in two or more parallel rows between which are formed intermediate ventilation ducts (3), which are open to the outside through the bottom and the cover.

Abstract: Handle for accumulator battery comprising a central grip and two steps on each side of the grip. The outer end walls of the steps have rounded perimeters. Each outer step is provided with an oval opening intended to cooperate with a respective pivot which the battery cover has on its opposite sides. The oval shape of the pivot cooperates with the oval shape opening due to their orientation to prevent removal of the handle at either a folded down or upraised orientation. The span of the first steps of the handle covers the terminals of the battery, and each first step permits anchoring of the cover-pieces over the terminals.

Abstract: Electrical storage cell battery comprising electrically interconnected cells each comprising positive plates, negative plates, intermediate separators and free or immobilized electrolyte, each cell further comprising an independent cylinder which ends on its open top in a common prismatic vessel, with all cylinders placed parallel to and near each other. In the same plane, the vessel is provided at least on its external lateral surface with complementary connecting elements for mechanical attachment to other vessels, including female connecting elements and male connecting elements provided on at least two of the opposite faces of the vessel. The connecting elements may also be placed on the cylinders.

Abstract: Positive electrode and special lead accumulator for use at high temperatures, which is provided with a holder based on a special lead alloy with improved behavior against corrosion, The alloy comprises from 1 to 5% of antimony, from 0.5 to 3% of tin, from 0.05 to 0.50% of arsenic, from 0 to 0.05% of copper and from 0 to 0.02% of bismuth.

Abstract: A machine for cutting electric battery plates, comprising two rollers (17, 18), between which a metal strip (20) passes. The metal strip is provided with a row of holes (22) running down the center, separated by bridges (31). The lower roller (17) is provided with means for removing cut-away pieces. A disk that is selectively circumferentially positioned is mounted on the lower roller. Lugs (21) project radially from the disk to pull the strip (20) along. Cutter plates (25, 26) are mounted on the upper roller. The cutter plates are provided with blades (29, 30) that cut the strip (20) and the bridges (31) transversely to yield plates (32) with their respective tabs (33). Inserts (35, 36) are provided under the cutter plates.

Abstract: A multicell electric storage battery with a prismatic container (1) and cylindrical cells, which comprises throughpassing vertical conduits (15-16) opening through the lid and bottom and disposed among adjacent cells and intended for the circulation of air or another coolant and for the passage of threaded anchoring rods (17). The cylindrical walls of the cells include a planar upper segment with an opening through which the electrical connection of adjacent cells is made.

Abstract: An electric storage battery whose basic features are that it comprises four terminals electrically connected in pairs under the battery cover, which permits it to be used in any type of vehicle regardless of the position of its collectors, and the arrangement of two C-shaped handles pivotally connected at their ends to two vertical partition walls and capable of occupying two positions, (1) a vertical position in which they function as a handle and (2) a horizontal position in which they permit the batteries to be stacked while protecting the terminals from possible damage from the stacked weight and the shock or rubbing of one battery against the other.

Abstract: In a method for sealing a substantially straight intercell connector bar passing through an opening in the upper part of an intercell partition of an electric storage battery, a mould is used having a marginal portion fitting against the face of the partition and defining a cavity, the mould comprising a body open at the bottom, and a closure movable horizontally from a closed position in which it extends under the bar to close the bottom of the cavity, to an open position in which it permits removal of the mould. The closure is formed with a cutter portion arranged to gouge or broach a groove in the upper or lower surface of the bar to ensure leak-proof closure of the mould.
