  • Patent number: 7311956
    Abstract: A laminate for use in decorating a receptor surface (e.g., a window) comprising a piece of decorative sheet material with a layer of aggressive pressure sensitive adhesive on its rear surface and a release liner over that layer of adhesive; and a flexible, temporary support tape comprising a backing and a layer of repositionable pressure sensitive adhesive on a second surface of the backing.

  • Patent number: 7284734
    Abstract: A hanger comprising a base having a supported surface adapted to be positioned along a generally vertical surface, and an elongate peg having one end mounted on the base with a portion of the peg projecting from an outer surface of the base opposite its supported surface generally at a right angle with respect to the supported surface of the base. The peg has an axially extending surface portion adapted to be positioned uppermost when the supported surface of the base is positioned along a generally vertical surface, which axially extending surface portion restricts free movement axially of the peg of sheets of paper around and hanging on the peg. That axially extending surface portion can be defined by a layer of adhesive on the peg or by closely spaced sharp edges on the peg. Such sharp edges could be on screw threads around the peg, ridges extending transversely across the peg, serrations formed on the peg, or by abrasive granules adhered along the peg.
