  • Magnetostrictive closure member
    Patent number: 3968898
    Abstract: A bimetallic closure member comprised of two materials having dissimilar magnetostrictive characteristics does not require a hinge, when subjected to a magnetic field, or alternatively, when removed from a magnetic field, the materials contract or expand at different rates causing the member to bend thereby opening or closing the closure member.
    Type: Grant

    Inventor: Andrew E. Beer
  • Magnetostrictive fastener arrangement
    Patent number: 3951560
    Abstract: Magnetostrictive fastener arrangement that relies upon the fractional change in length of a ferromagnetic element under the influence of a magnetic field (magnetostriction) to alter the physical cooperating relationship between the element and a second element. Each of the elements may exhibit the same or a different magnetostrictive effect in the presence of a magnetic field, and each of the elements is dimensioned so that a different physical relationship between the elements is achieved when either or both elements undergoes a fractional change in length.
