  • Miniature galvanic cell having optimum low surface area conductive collector
    Patent number: 6051337
    Abstract: A miniature galvanic cell employing a cup-insulating member-current collector assembly, preferably a plastic insulating member and low surface area current collector, to prevent or minimize the formation of gases, such as hydrogen, on the current collector member. A process for producing such a cell is also disclosed.
    Type: Grant
    Filed: November 14, 1997
    Date of Patent: April 18, 2000
    Assignee: Eveready Battery Company, Inc.
    Inventor: Henry Heinz, Jr.
  • Miniature galvanic cell having optimum internal volume for the active components
    Patent number: 6033799
    Abstract: A miniature galvanic cell tube employing a cup-tube assembly, preferably a shrunk tube, in which the tube occupies a minimum volume so that the internal volume of the cell can be maximized to contain the acting components of this cell and a process for producing the galvanic cell.

  • Galvanic cell having a primary radial seal and a secondary resealable vent closure
    Patent number: 4112200
    Abstract: A galvanic cell having a primary radial type seal in conjunction with a secondary resealable vent closure, said resealable vent closure comprising a resilient elastomeric sponge gasket disposed and compressed between the upper surface of the cell's cover and the rim of the cell's container, which is turned over the upper surface of the cover, so as to facilitate the venting of any high pressure gases that may escape past the radial seal while retaining liquid.

    Assignee: Union Carbide Corporation
    Inventor: Henry Heinz, Jr.
  • Method of making a galvanic cell having a resealable vent closure
    Patent number: 4063902
    Abstract: A galvanic cell, and a method for making it, having a resealable vent closure consisting of a resilient elastomeric sponge gasket disposed and compressed between the cover of the cell and the upper wall of the cell's container and designed such that gas buildup within the cell in the range of about 5 to 75 psi will vent along the cover-gasket interface and/or container-gasket interface.
    Type: Grant
    Filed: January 28, 1977
    Date of Patent: December 20, 1977
    Assignee: Union Carbide Corporation

  • Pressure relief flapper vent valve for galvanic cells
    Patent number: 4052533
    Abstract: A galvanic dry cell having a resealable subseal comprising a cup-shaped flapper vent valve having an opening at its center for receiving and contacting the cell's current collector rod and a peripheral edge segment contacting and conforming to the inner wall of the cell's container and adapted for deflecting upwardly thereby providing a resealable vent path at the valve-container interface.
