  • Radiation-curable, cyanoacrylate-containing compositions
    Patent number: 6867241
    Abstract: The present invention relates to a radiation-curable composition which includes a cyanoacrylate component or a cyanoacrylate-containing formulation, a metallocene component, a hydrogen abstraction photoinitiator, and hydrogen donor component to enhance the activity of the hydrogen abstraction photoinitiator.
    Type: Grant

  • Detection system
    Patent number: 6600509
    Abstract: A detection system (10) utilising projected light (18, 20) viewed through an appropriately placed camera (22) detects variations in surface height (26). The system (10) is arranged to project light onto the surface (16) of interest. A camera with optical axis (24) oriented parallel to and offset from the direction of light projection is used to image the intersection (50, 66) of the projected light (18, 20) with the surface (16). The system (10) observes deflections (64) of this imaged intersection (66) and associates them with the movement of an object (26, 124) through the projected light. The object can range from a surface irregularity (124) to a person (26) walking along a corridor.

  • Cyanoacrylate compositions
    Patent number: 6475331
    Abstract: This invention relates to cyanoacrylate-containing compositions that include, in addition to the cyanoacrylate component, the combination of two accelerators to improve fixture speeds on certain substrates.
    Type: Grant

    Inventors: John T. O'Connor, Roger J. Grismala
  • Toughened cyanoacrylates containing elastomeric rubbers
    Patent number: 4440910
    Abstract: Disclosed are cyanoacrylate adhesive compositions containing elastomeric polymers as fillers. Preferred fillers are the acrylic rubbers. Filler concentration range from about 0.5-40% by weight of the composition. Beneficial results include improved toughness of the cured compositions, as measured by impact, peel and tensile strength properties, particularly after exposure elevated temperatures which would ordinarily severely degrade the adhesive strength.
