Abstract: A bolo style clasp or slide is modified and improved by affixing an engagement apparatus to its posterior surface. The engagement apparatus can vary in both size and specie so as to best accommodate the intended coupling item. The addition of the engagement apparatus expands the versatility of the bolo style clasp or slide by allowing it to serve its original ornamental function and any one of several utilities. Further, the anterior surface of the bolo style clasp or slide is hinged so as to allow the surface to rotate exposing an interior area. The interior area can be used for the storage of small items or situating an exchangeable ornamental face.

Abstract: An apparatus and method of coupling standard exhaust tubing of a circular cross-section with irregular or non-circular exhaust ports of an internal combustion engine in an efficient, economic, and robust manner. The nature of the connection allows for irregular or non-circular exhaust ports to be mated to round tubing with minimal air flow impact and a high strength welded connection, with reduced manufacturing scrap and increased CNC manufacturing capability.
