  • Publication number: 20050241186
    Abstract: The present invention relates generally to a printed film innersole (PFI) and a process for making the same. The present invention provides to a PFI and a process for the construction of an innersole for post-insertion into a shoe that can have significant design details added to the bottom surfaces.

  • Publication number: 20050097658
    Abstract: The present invention relates to a cushioning laminate insert for a garment shoulder strap, such as a brassiere strap. The cushioning laminate insert of the invention includes: (1) a first outer fabric layer; (2) a central cushioning area of cured polyurethane elastomer cushioning material; and (3) a second outer fabric layer. One surface of the first and second outer fabric layers is laminated with a thermoplastic urethane (“TPU”) film. The laminated surface of the first outer fabric layer is covalently bonded to a first lateral surface of the central cushioning area, and the opposite lateral surface of the central cushioning area is self-adhered to the laminated surface of the second outer fabric layer in an open-sandwich configuration to thereby form the cushioning laminate insert. Garment shoulder straps including the cushioning laminate insert of the invention, as well as methods for making the cushioning laminate insert are also provided.

  • Patent number: 6260861
    Abstract: Disclosed is an in-line skate wheel that includes: (a) a braking portion including a high friction surface material having a hardness from about 75 to about 95 Shore A, and a coefficient of friction from about 0.45 to about 1.5; and (b) a skating portion including a low friction surface material having a hardness from about 75 to about 95 Shore A, and a coefficient of friction from about 0.1 to about 0.45. The skating portion includes a higher proportion of low friction surface material than the braking portion. The wheel delivers variable traction in response to the angle of wheel contact with the ground, without sacrificing a smooth ride or wheel durability. Utilizing the variable traction of the wheel a skater can stop safely and reliably, using known ice-skating maneuvers, wherein the wheel is turned away from the skater's direction of travel.
