A balloon or self expandable endoprosthesis formed of a single or multiple joined stent sections. Each section has a node and strut structure extending throughout in order to uncouple expansion forces of the stent to hold a blood vessel outward from crush forces that resist the formation of an oval shape during a crush deformation. The hinge can bend in the direction of a uniformly curved surface of the stent but not in the radial direction. The strut can bend in the radial direction but not in the uniformly curved surface of the stent. The widths, lengths, and radial dimensions of the hinges and struts provide a balloon-expandable hinge stent that is non-crushable. For a self-expandable stent the hinge and strut dimensions provide expansion forces that are controlled independently from crush forces. Expansion properties are determined by the hinge dimensions and crush properties are determined independently by the strut dimensions.

An abradable coating and / or an abrasive coating applied to the rotor of a steam or gas turbine allows the temperature and pressure drop capabilities of conventional brush seal assemblies to be increased. The pressure drop capability of brush seals is closely related to fence height, i.e., the distance between the rotor and the bottom edge of the backing plate supporting the brush seal wire bristles. Application of the abradable or abrasive coating allows the fence height to be reduced and the pressure capability of a brush seal assembly increased commensurately because the risk of the backing plate rubbing against the surface of the rotor, so as to cause damage to the rotor, is reduced. In addition, the backing plate can be made from a higher strength material that can withstand higher temperatures because any contact between the backing plate and the rotor results in no damage to the rotor, but rather a gradual reduction of the backing plate as it wears.

The present invention relates to a load and moment sensor for a prosthetic device detecting load in a single direction and moment in a single plane.

An improved pulper, mixer or defibering, rotor having a spar ring attached to a hub of the rotor with a series of curved vanes projecting from the spar ring. The curved vanes have a vane face and a trailing edge. The trailing edge may be unitary and integral with the vane, or may be segmented in combination with trailing edge portion provided on an underlying spar stub to which the vanes are attached. The hydrodynamic suction created by the trailing edge is enhanced by the addition of a dam at the vane tip end of the trailing edge zone. The vanes have a constant vane face angle relative to radians extending outward from the hub of the rotor. As a result of the constant vane face angle the pulp, or other materials, mixed by the vanes during rotation of the rotor are more consistently in contact with the vanes during rotation of the rotor. The vanes are also streamlined to reduce hydrodynamic drag especially at the vane tips where speed and therefore drag potential are at their highest levels. As a result, increased circulation and pumping effects with minimal power requirements are achieved. The vanes may be made of high wear resistant materials and are easily accessible for maintenance, repair or replacement.
