  • Electrode grid for lead batteries
    Patent number: 6228537
    Abstract: The invention pertains to an electrode grid for lead batteries with a rectangular grid frame, pasting accessory rails arranged on it, and a group of grid cross members which form the skeleton to hold the active mass, the pasting accessory rails extending on both sides of the electrode grid solely in the pasting direction and, especially on the front and back side of the electrode grid, are arranged offset from each other.
    Type: Grant

    Inventors: Gerolf Richter, Joachim Illmann, Peter Streuer
  • Gas and liquid tight pole seal for electric storage batteries, particularly lead storage batteries
    Patent number: 4522899
    Abstract: A hermetic pole seal for lead storage batteries which averts the customary use of lead sleeves, involves a first ring-shaped molding surrounding the pole shaft with a rubber-elastic synthetic plastic (thermoplastic rubber) and a second molding covering the former with a less elastic synthetic, which is preferably identical to the case material (e.g. polypropylene), followed by mirror welding to the lid. The sealing of the pole lead-through results from material shrinkage following the molding. In so doing, the different plastics mesh from opposite sides.
    Type: Grant
    Filed: September 16, 1983
    Date of Patent: June 11, 1985
    Assignee: Varta Batterei A.G.
    Inventors: Joachim Illmann, Klaus Gummelt
  • Clamping element for storage battery plate stacks
    Patent number: 4501413
    Abstract: A plate stack clamping element is formed of adjacent leaf springs preformed to diverge where they extend beyond the plate stack. Compression of the diverging portions creates large area contact clamping force against the plate stack.
    Type: Grant
    Filed: January 28, 1982
    Date of Patent: February 26, 1985
    Assignee: Varta Batterie Aktiengesellschaft
    Inventors: Joachim Illmann, Heribert Fullgraf
  • Plate stack clamping apparatus for storage battery manufacture
    Patent number: 4361316
    Abstract: The plate stacks are positioned for further processing in a clamping arrangement with clamping elements between stacks. Each element is displaceable by an amount of play X with respect to its neighboring element.

  • Lead dosing valve
    Patent number: 4114649
    Abstract: A valve body has outlet ducts to be positioned below the surface of the molten lead, and a head rotatable with respect to the body. The head has recesses which terminate in slots that can be aligned with the outlet ducts to open the valve. These slots have smaller cross-sections than the ducts. The body also has open ended passages which align with the outlet ducts when the valve is closed.
