Abstract

It is the object of the invention to provide a knee bracing system that bolsters the body's natural ligaments to reduce the knees proneness to injury or re-injury. The invention is a cable system that acts much like the body's natural way that resists the forces that cause excessive joint movement and injury to the ACL and or MCL. As the leg travels through the range of motion the cables provide external hyper extension, bending, and rotation support preventing the tibia bone from moving forward (hyper extending) or twisting (lateral rotation) and or laterally bending with respect to the femur.

Abstract

An embodiment relates to a redispersible polymer powder (RDP) composition for use in the preparation of dry mortar formulations, especially of cementitious bound tile adhesives (CBTA) and adhesives for external thermal insulation composite systems (ETICS). An embodiment further relates to a dry mortar formulation comprising said RDP composition. Embodiments relate to the composition and manufacture of water-redispersible polymer powders that comprise polyurethane powders, particularly where said polyurethane powders comprise particles of ground polyurethane foam. An embodiment is further directed to a method of improving adhesion of said polyurethane powder particles to mineral components of a dry mortar formulation. Furthermore, an embodiment is directed to a method of improving impact resistance of a cured dry mortar formulation without deteriorating workability of the wet mortar or the adhesion strength of the cured dry mortar formulation.

Abstract

The embodiments of the invention are directed to a composite material comprising a fiber reinforcing material, a binder resin and polyurethane foam particles. Other embodiments are related to a process for manufacturing a composite material comprising a fiber reinforcing material, a binder resin and polyurethane foam particles, the method comprising depositing the binder resin and polyurethane foam particles the fiber reinforcing material to form a composite precursor and treating the composite precursor to form the composite material
