Granted: 2004-03-02
Abstract: A resorbable implant (41) for interposition arthroplasty which is intended to fill a void between two adjacent bone ends, providing a cushion between the bone ends to prevent impingement of the bone ends while providing time for tissue to infiltrate into the space occupied by the implant (41). It has a protracted resorption time of preferably at least three months to allow time for the proliferation of load-bearing host fibrous tissue in place of the resorbed implant material. The implant (41) preferably is porous with a pore size of greater than about 80 microns in order to enhance infiltration of fibrous tissue. The implant (41) has a modulus in the range of 0.8 to 20 MPa which is soft enough to allow it to conform to surface irregularities of the adjacent bone surfaces while being hard enough to maintain a desired separation between those bones (13, 15, 17, 19) while tissue infiltration replaces the resorbable implant material. The implant (41) may be preformed to the desired shape or alternatively may be formable by the surgeon by methods such as carving with a scalpel. A preferred application for the implant is as a trapezium bone (11) replacement.

Abstract: A turbo fan engine nacelle houses an engine which forces engine exhaust through a primary nozzle and a fan nozzle positioned along a common central axis. The primary nozzle is bordered interiorly by a primary nozzle plug and bordered exteriorly by a primary nozzle sleeve. The fan nozzle is bordered interiorly by a core cowl and bordered exteriorly by a fan nozzle sleeve. The primary nozzle plug includes a generally cone shaped outer surface which is concave when viewed in side elevation. The concave outer surface has a radius of curvature (R c).  The core cowl has a distal end which is radially spaced from the outer surface of the primary plug by a distance (.DELTA.H) in a direction perpendicular to the central axis. The primary nozzle plug and core cowl define a ratio R c/.DELTA.H between approximately 14 and 18. The distal end of the core cowl has a core cowl radius R p with respect to the central axis. A discharge end of the fan nozzle sleeve has a fan nozzle sleeve radius R f, wherein a ratio R p/R f is between approximately 0.4 and 0.6. The outer surface of the primary plug forms a primary plug angle ~p between approximately 13° and 19° with respect to the central axis at the primary nozzle exit. The proper scaling of these key dimensions thereby defines a primary nozzle which reduces the shock associated noise of the turbo fan engine.
