Abstract: A machine for the casting and subsequent stamping of grids for lead storage atteries, particularly ones consisting of low-Sb and Pb-Ca alloys, has a pouring nozzle to receive and pour a predetermined amount of melt into a casting mold arranged vertically beneath it. For removal from the mold, conveyance and machining of the castings without deformation, particularly if soft alloys are used a lifter for the casting is arranged on the casting mold, by means of which lifter the casting can be brought while remaining in its vertical position onto a conveyor device which is developed as a cooling path for hardening of the casting. At the end of the path a deflection unit repositions the casting which has been transported vertically up to this point into a horizontal position and by a feed device is advanced to a stamping machine from where the grid passes onto a conveyor belt.

Abstract: An electrochemical battery for production of high outputs and efficiencies with high current densities comprising a plurality of cells, particularly metal-air cells each comprising a consumable electrode, and an air electrode spaced from the consumable electrode with electrolyte disposed in an electrolyte space and current take-off. The consumable electrode has a rod-shape made at least partially of a dense metal, the consumable electrode having a front face constituting a sole working surface projects sealed-off into the electrolyte space. An air electrode is spaced by the smallest distance parallel to the working surface of the consumable electrode, and an adjustable mounting for one of the electrodes maintains the spacing between the electrodes constant. The cells are arranged parallel to one another and connected in series, the air electrode and the consumable electrode of each of the cells being reversed with respect to the consumable electrode and the air electrode of the adjacent cell.

Abstract: A reaction catalyst for the recombination of the oxyhydrogen gas produced by lead-acid storage batteries into water in a controlled, exothermic reaction, where the catalyst element is a solid rod element with a central heat conducting core, the catalyst rod being positioned inside a gas-tight housing in communication with the battery gas space. This rod element is produced by a fabricating method in which granular catalyst carrier material is worked into a paste which is then shaped and dried, the metallic catalyst being deposited on the surface of the carrier grains.

Abstract: A method for the production of high outputs with high current densities in an electrochemical system, particularly of a metal-air-cell having a consumable electrode, an air electrode and electrolyte disposed between the electrodes. The heat occurring in the phase boundary interface electrode/electrolyte or the existing temperature is controlled in the sense of a local heating and/or cooling.

Abstract: A lead storage battery with positive and negative plates, the contact lugs of which respectively are connected with one another by lug bridges. The grid upper part of each plate grid is covered with an acid resistant synthetic material covering, which synthetic material covering surrounds the contact lugs acid-tight, the synthetic material covering being connected acid tight with the cell cover or one-piece composition case cover. The lug bridges are connected with one another outside of the acid space of the contact lugs.

Abstract: A device for production of high outputs and efficiencies with high current densities in an electrochemical system, particularly a metal - air cell, comprising a consumable electrode, an air electrode, an electrolyte disposed in an electrolyte space and current take-off. The consumable electrode has a rod-shape spacial form made at least partially of compact metal, the consumable electrode having a front face constituting a sole working surface and projects sealed in the electrolyte space. An air electrode is spaced by the smallest distance parallel to the working surface of the consumable electrode, and an adjustable mounting for one of the electrodes, particularly the consumable electrode, uniformly maintains the spacing between the electrodes in the axial direction.

Abstract: A substance, a method of producing it, and a device for using the substance in the absorption of catalyst poisoning gases out of the oxyhydrogen gas mixture produced by lead-acid storage batteries, the substance effecting the oxidation of the unstable catalyst poisoning gases SbH.sub.3 and AsH.sub.3 to produce hydrolysis-resistant intermetallic compounds. As absorbing substances are usable heavy-metal manganites, heavy-metal oxides and catalytic agents. As a device, the absorbing substance is combined with an oxygen and hydrogen recombination unit.

Abstract: A device for positioning the storage plates and insulating plates of lead-acid storage batteries for the assembly of battery cells in such a way that the longitudinally larger insulating plates form a uniform lateral overhang on both sides, the device including two oppositely spaced parallel positioning members with inwardly protruding positioning knives cutting notches in the edges of the insulating plates. The positioning members, or only the positioning knives alone, are retractable horizontally.
