Abstract: A folding cart is disclosed which has a forward section, a main section, and a rear section, along with forward and rear end rails and left and right side rails. The forward and rear portions of the left and right side rails fold to a coplanar position with the main portion of each respective side rail, while the forward and rear end rails fold down to a position coplanar with the forward section and rear section, respectively. The forward and rear sections may then be rotated to a position over the main section. The forward and rear sections each have mounted to their bottom surfaces a dual wheel assembly, each dual wheel assembly having a pair of wheels which may be folded to a position parallel to their respective forward or rear section. The forward dual wheel assembly is mounted to the front section of the folding cart a rotating pivot, while the rear dual wheel assembly is mounted directly to the rear section. Finally, a folding handle is provided which is attached to the forward dual wheel assembly.

Abstract: A tubing swaging machine comprising four coplanar hydraulic cylinders which compress the end of a piece of tubing around a central mandrel. The central mandrel has indentations and is reciprocated by a fifth hydraulic cylinder perpendicular to the plane of the other four cylinders. Each of the four coplanar hydraulic cylinders reciprocate a die which has a surface corresponding to the indentation in the mandrel opposite.
