Abstract: A decorative floor tile including at least one decorative layer and a backing layer having an array of resilient annular projections. Each annular projection includes a concave top surface, an outside wall surface, and an inside wall surface. The inside wall surface defines a central, blind passageway area. When the decorative floor tile is installed over an underlying surface, and pressure is applied to the decorative floor tile, a vacuum is created within the blind passageway and the underlying surface. The vacuum increases the amount of frictional drag between the surface covering and the underlying surface, and thus allows the surface covering to remain in place without the need for an adhesive.

Abstract: A multi-layered material composite is disclosed suitable for nuclear reactor applications to protect equipment from radiation damage. In one embodiment, the composite includes an internal neutron-absorbing layer and an external layer disposed on opposing sides of the internal layer. The external layers are made of metal or ceramic in various embodiments. The composite is disposed on or at least proximate to the an equipment component within the containment chamber of a nuclear reactor in some embodiments to protect the component from radiation damage.

Abstract: This invention describes a decorative surface covering comprising at least one decorative layer and a backing layer comprising a patterned array of elastomeric, geometric projections, wherein each geometric projection comprises a concave exposed surface, an outside wall surface and an inside wall surface wherein the inside wall surface defines a hollow area within the projection. When the decorative surface covering is installed over an underlying surface, and pressure is applied to the decorative surface covering, a vacuum is created within the hollow area of the projections and the underlying surface. The vacuum increases the amount of frictional drag between the surface covering and the underlying surface, and thus allows the surface covering to remain in place without the need for an adhesive.
