The invention reduces wear in total joint articulations by modifications of the shape of either component of the kinematic pair, so as to result in an annular surface contact between the two components. Fluid trapped between the two components within the inner contour of the annular contact area is pressurized under load due to elastic deformation of the components and exuded out through inter-articular gap over the surface of contact, aiding in lubrication and reducing the wear. Reduced to practice for a total hip joint with UHMWPE-metal pair, the wear rate tested in a hip joint simulator up to five million cycles was reduced by factor seven to fifteen compared to conventionally shaped components.

A method for improving the wear characteristics of a system for operating a variable vane comprising the steps of providing a trunnion connected to the variable vane via an vane platform and means for causing rotation of the trunnion, and positioning a thrust washer formed from a carbon material about a lower portion of the trunnion and in a space between the vane platform and an outer split case so that during operation of the system the space between the vane platform and the outer split case is maintained substantially constant and unwanted deflection of the vane is avoided.

The present invention relates to a urethane-based coating having nanoparticles for improving the characteristics of a papermaking process belt, roll cover and belts used in textile applications. For example, the present invention improves resistance to flex fatigue, crack propagation, groove closure and wear characteristics of urethane coatings on such belts and roll coverings. The present invention also improves the resistance to water and oil permeation characteristics of urethane coated belts and roll coverings.

An improved prosthetic medical device having improved wear resistance and toughness is provided in the present application. A method is provided to selectively cross-link the polymeric matrix comprising the medical device by employing an interrupting means such as a mask, wire mesh or chopper wheel placed in between the medical device and irradiation source. In addition, the medical device may be translated while being irradiated to further effect the selective cross-linking. The present invention also provides for an injection molding process wherein a prosthetic medical device is formed in a single step, then selectively cross-linked.

A one-piece inner garnish assembly module system (MS) joins an inner garnish molding (IG), primary seal (PS), glass run (GR), and inner beltline weatherstrip (IB) into a single component prior to installation of the module system on a vehicle. The garnish is secured to the glass run along the A and B pillars, and the interconnecting header portion of a vehicle door. In addition, the primary seal is operatively associated or secured to the garnish, and may be pin-mounted to the door, or mechanically connected, and / or adhesively secured to the door.

Disclosed is a coating agent comprising a cellulose derivative, a 1,2-polybutadiene having an isocyanate group, a synthetic wax having a softening point of 100 to 150 DEG C, an aliphatic amide having a softening point of 60 to 170 DEG C and graphite. The coating agent has satisfactory levels of properties required for a coating agent for a rubbery elastic material, such as a sticking-preventing property, an adhesion-preventing property, a blocking-preventing property, and improved abrasion resistance. The coating agent can be used as a surface treatment agent for a vulcanized rubber, which does not cause adhesion upon compression at a high temperature or detachment of a coating film by friction / abrasion under a high surface pressure.

An equestrian stirrup insert for enhancing the stability and traction of the stirrup foot plate. In this regard, the present invention provides for a traction enhancing insert assembly that is installed into the foot plate of stirrups. The insert is formed from milled aluminum. The milled aluminum plate provides a durable surface that has greatly improved wear characteristics. The assembly includes a top traction surface that is placed onto the foot plate of the stirrup. A mounting plate is placed beneath the stirrup and connected to the underside of the traction surface using fasteners. Since the insert is rigidly fixed to the stirrup using fasteners, the insert is prevented sliding in the stirrup. In this manner, the rigid relation ship between the insert and the foot plate of the stirrup allows for enhanced force transfer from the rider's foot into the stirrup with a greatly reduced potential for the insert to slip relative to the stirrup.
