  • Flexible electrical connectors for electrolytic cells
    Patent number: 10855040
    Abstract: A flexible electrical connector assembly is adapted to connect a bus bar of an electrolytic cell to a collector bar of the electrolytic cell. The assembly includes an electrical connector including a plurality of conductive metal sheets, the electrical connector having a collector bar end and a bus bar end. The electrical connector may be adapted for being joined, at the collector bar end, to the collector bar and, at the bus bar end, to the bus bar. The electrical connector may be adapted to implement a change in direction, at a bend along a current-carrying path between the bus bar end and the collector bar end, the bend assisting to define the change in direction as greater than 90 degrees.
    Type: Grant

  • Concave for a combine harvester
    Publication number: 20050197176
    Abstract: A concave for a combine harvester includes a body consisting of a grid of straight longitudinal bars arranged in a concave configuration. Each of the longitudinal bars have a leading face, a trailing face, and an upper extremity. At least one of the longitudinal bars has a longitudinal cavity positioned along the leading face at the upper extremity. A wear resistant insert is positioned in the longitudinal cavity. The wear resistant insert is detachably secured to and receives underlying support from the said at least one of the longitudinal bars. The wear resistant insert provides a replaceable leading edge.
