Abstract: A fume exhaust duct joint, a clamping collar for clamping two cylindrical dual-laminate duct sections joined by an internal slip collar, and a method for assembling the joint. A first embodiment of the clamping collar has two clamp portions each including a metal outer skin spot-welded to a metal inner skin. The inner skins have bifurcated protrusions whose bifurcations penetrate the duct section outer surfaces when the collar is tightened, and, optionally, two circumferential beads of fire retardant caulking. The inner skins and slip collar are bonded to duct section surfaces using a putty-like sealant including a settable admixture of curing agent and novolac epoxy resin. A second embodiment of the clamping collar, preferred for duct sections 3-inches in diameter or smaller, has a single circumferential clamp portion.

Abstract: An improved acetabular cup prosthesis has a cup body with inner convex and outer concave surfaces. The cup body has an apex and a base that defines a plane. The cup body outer convex surface has a curved annular portion between the base and the transition. In one embodiment, the outer convex surface is a curved annular surface extending in between the rim and a distance about two fifths to three fifths (2/5-3/5) of the distance between the rim and the apex. In another embodiment, a plurality of cup bodies are provided in a range of sizes between about 40 mm and 80 mm. Each cup body has a companion rotary reamer that is correspondingly shaped. The companion cup body is oversized between about 1 mm and 3 mm so that a generally constant change in volume is provided for all cup sizes between 40 mm and 80 mm.

Abstract: An improved acetabular cup prosthesis has a cup body with inner convex and outer concave surfaces. The cup body has an apex and a base that defines a plane. The cup body outer convex surface has a toroidally shaped portion between the base and the transition. In one embodiment, the outer convex surface is toroidally shaped between the rim and a distance about one third of the distance of the rim to the apex. In another embodiment, a plurality of cup bodies are provided in a range of sizes between about 40 mm and 80 mm. Each cup body has a companion rotary reamer that is correspondingly shaped.
