  • Flame retardant carbonate polymers and use thereof
    Patent number: 6518347
    Abstract: Flame retardant carbonate polymer compositions and articles prepared therefrom are described. The carbonate polymer contains a flame retardant additive comprising metal salts of a highly fluorinated methide, amide or imide anion. The composition provides flame retardancy at relatively low levels of additive, allows a broader processing window of additive compositions and can have high transparency.
    Type: Grant

  • Bis (perfluoralkanesulfonyl)imide surfactant salts in electrochemical systems
    Patent number: 6280883
    Abstract: Electrolyte compositions and electrochemical systems containing such compositions are described where the electrolyte includes in a matrix material a combination of a conductive salt and a bis(perfluoroalkanesulfonyl)imide surfactant salt. The compositions improve wettability of electrodes and separators while maintaining and improving conductivity, stability, and compatibility with other cell components.

  • Breakaway post coupling
    Patent number: 5535555
    Abstract: A breakaway post coupling with a hollow, tubular sleeve which accomodates a ground-mounted stub post and a top, sign-supporting post. The sleeve is held onto the posts by a plurality of pins which engage a corresponding plurality of slots in the sleeve. Collars slidably engage the sleeve and force the pins into the post material as the collars are drawn over the sleeve and pins. A plurality of cutouts in the sleeve define a shear point in the coupling. When the top post is struck by a vehicle, the coupling breaks at the shear point, leaving an intact stub post upon which a new top post can be joined.
