  • Controlled dispersion of colloidal suspension by comb polymers
    Patent number: 7053125
    Abstract: Comb polymers are used as dispersants to increase the stability of colloidal suspensions containing multivalent or high concentrations of monovalent ions. Stabilized colloidal suspensions and methods of forming stabilized colloidal suspensions are described, including suspensions containing ceramic precursors or bioactive agents useful in forming ceramic substrates or pharmaceutical compositions, respectively.
    Type: Grant
    Filed: January 3, 2003
    Date of Patent: May 30, 2006
    Assignees: The Board of Trustees of the University of Illinois, W.R. Grace & Co.-Conn.

  • Drag mounted spring for spin-cast reels
    Patent number: 6056223
    Abstract: A spool rotational alert spring mounted to a disk drag, for use in a fishing reel of the spin-cast type, having a body with a fixed hub for supporting a line carrying spool.The disk drag supported non-rotatably on the hub is a unitary device that performs both the function of applying drag pressure against the wall of the spool and mounting a spool rotational alert spring with its free end engaging annularly disposed serrations on the wall of the spool, to produce an audible alarm alerting the user when the line carrying spool rotates against the disk drag that line is being withdrawn.

  • Lubricant retaining drag for spin-cast reels
    Patent number: 5950947
    Abstract: A fishing reel of the spin-cast type, having a body with a fixed hub, a line carrying spool rotatably supported on the hub. The reel having rotatable and non-rotatable drag washers operating on the spool creating a drag assembly. For smooth drag action during heavy usage, a lubricant retaining cavity is positioned in the drag surface of a drag assembly member. The use of a lubricant retaining cavity being optional in one or all drag assembly members, that which provides the drag action desired. A lubricant retaining cavity positioned in the drag surface permits the cavity to be covered, and retains lubricant in the cavity when the drag surfaces are engaged. The spool rotates as line carried thereon is drawn therefrom, permitting lubricant to be wiped from the retaining cavity and about the engaging drag surfaces, thereby becoming a self lubricating drag assembly.
