International Classification:

C09J 133/14
A61F 2/30
A61M 5/19
A61K 47/32
B65D 85/00

US Classification:

623 1811, 526312, 524555, 526208, 522 96, 526213, 526217, 526210, 5147726, 206568, 604191

Abstract:

Methods, compositions, and kits for adhering polymers and other materials to another material, and in particular to bone or bone-like structures or surfaces. A composition of matter includes a urethane dimethacrylate-methyl methacrylate copolymer with a plurality of first polymer regions based on urethane dimethacrylate and a plurality of second polymer regions based on methyl methacrylate. The method includes placing an orthopedic joint implant having an attachment surface in a joint space, applying a first non-urethane-containing precursor, a second urethane-containing precursor, and a initiator to the attachment surface; contacting the first and second precursors and the initiator with the joint surface; and copolymerizing the first and second precursors and forming an adhesive copolymer and attaching the implant to the joint.

Abstract:

A structure of a floating, semi-submersible wind turbine platform is provided. The floating wind turbine platform includes three elongate stabilizing columns, each having a top end, a keel end, and an outer shell containing an inner shaft. Each stabilizing column further includes a water entrapment plate at its keel cantilevered in a plane perpendicular to a longitudinal axis of the stabilizing column. The floating wind turbine platform also includes three truss members, each truss member including two horizontal main tubular members and two diagonal tubular members. The truss members connect the stabilizing columns to form a triangular cross-section. An elongate wind turbine tower is disposed over the top end of one of the three stabilizing columns such that the longitudinal axis of the tower is substantially parallel to the longitudinal axis of the stabilizing column.
