Abstract:
This invention relates to a fabricated vehicle wheel and method for producing the same. The wheel includes a rim and a disc secured to the rim. The disc includes a plurality of outwardly extending spokes, an outer rim connecting flange defining a side edge surface and a window formed therein between adjacent pairs of spokes and having a predetermined shape defined by the adjacent pairs of spokes and the side edge surface of the rim connecting flange such that each of the windows extends to an outermost periphery of the wheel disc, at least one of the windows includes at least a first window portion and a second window portion, the first window portion being formed by a first piercing operation and the second window portion being formed by a second piercing operation.

Abstract:
A surgical staple is used in joining the skin or fascia of a patient, and is especially desired to be used with mesh placed over a cut organ, such as the kidney. The staple is adapted to be formed about a central anvil and former. The configuration of the staple is such that at initial contact the points of the staple are formed at acute angles to the central portion of the staple. In this fashion, upon forming, a modified "B" shape is derived. This configuration has proven useful to reduce rotation of the staple when emplaced over mesh.
Abstract:
The invention relates to the use of the plasma concentration of the polypeptide “tissue inhibitor of metalloproteinase-4” (TIMP-4) as a biomarker for the diagnosis of heart failure.
Abstract:
The invention concerns a process for manufacturing ribbed tubes, wherein a stainless steel tube is provided with ribs by helicoidally winding a copper strip around it, and a ribbed tube thus manufactured. In joining the tube and rib, the unmelted copper strip is set on the tube surface edgewise into a melted area produced by a laser beam exclusively on the tube surface, thereby bonding the strip onto the tube by the solidification of the melted tube material. In this manner ribbed tubes can be provided, featuring an internal tube made of corrosion-resistant stainless steel and a helicoidal rib made of copper for increasing the heat exchange surface of the tube, which is distinguished by high thermal conductivity.
