  • Publication number: 20030131553
    Abstract: A non-metallic masonry tie includes at least two longitudinal members of composite fibre. Composite fibre reinforcement extends between the two longitudinal members. The preferred composite fibre reinforcement is in the form of a bundle of composite fibres extending angularly between and wrapped around the two longitudinal members to form a symmetrical reinforcement pattern consisting of a plurality of triangles. This serves to equally distribute the forces acting upon the two longitudinal members.

  • Patent number: 4085466
    Abstract: A prosthetic joint device is provided with first and second components respectively providing convex and relatively flat articulatory bearing surfaces, and a third component is located between the former components and has two surfaces which are complementary to and engage the convex and flat surfaces. Preferably the two pairs of engaged surfaces are suitably respectively spherically shaped and planar. The device can move under natural muscular and ligamentous control, in a varying manner closely simulating that of a natural joint which maintains uniform load distribution. Initial development centered on the provision of a knee joint endoprosthesis, but the mechanics of the device are well suited to other joints, particularly of non-congruous form, and also to joints in exoprostheses.
