The middle portion,is scyphate, i.e., cup-shaped, and defines a plane,,(FIG.,). The first portion,extends away from plane,in a given direction by an angle &agr;, which, in a preferred embodiment, is about 5 degrees. The end portion,is connected to the middle portion,by a reentrant section,and extends away from the plane,by an angle &bgr; in a direction opposite to the given direction. In a preferred embodiment angle &bgr; is preferably about 20 degrees. In a still more preferred embodiment the included angle between first portion,and end portion,is between 25 and 35 degrees. A centrally located aperture,is provided in the reentrant section,to aid in the subsequent bending of the end portion,at the final welding.
