Embodiments of golf club weight attachment mechanisms are described herein. In some embodiments, a golf club head comprises a head body with an interior cavity, a shell portion, and a bracket with a weight member coupled to the bracket. In one embodiment, the bracket and the weight member can be configured to be fully contained within the interior cavity. Other examples and related methods are also described herein.

An open frame prosthesis is formed with looped end terminations at its proximal and distal ends. At one end of the prosthesis, the filaments or strands are welded together in pairs to form strand couplings. A plurality of loop segments are connected to the strand couplings, one loop segment for each pair of adjacent strand couplings. In one version of the prosthesis, strands at the opposite end are bent to form looped ends. In another version, loop segments are connected to pairs of strand couplings at both ends of the prosthesis. The loop segments can be connected to the couplings by welding, fusion bonds, or tubes, which are either crimped or heat shrunk.

A stent is formed by encasing or encapsulating metallic rings in an inner polymeric layer and an outer polymeric layer. At least one polymer link connects adjacent metallic rings. The stent is drug loaded with one or more therapeutic agent or drug, for example, to reduce the likelihood of the development of restenosis in the coronary arteries. The inner and outer polymeric materials can be of the same polymer or different polymer to achieve different results, such as enhancing flexibility and providing a stent that is visible under MRI, computer tomography and x-ray fluoroscopy.

Methods and apparatus for making multiple broaching marks on the rules.

An assembly unit is produced according to the following method steps: an assembly part is provided which does not yet have a through bore. A disc-shaped welding element blank with a first end side, a second end side and a peripheral surface is stamped out of a sheet metal blank by a punch and a hole die so that the peripheral surface has a cylindrical longitudinal portion extending away from the first end side, and an adjoining cone portion which tapers towards the second end side and forms with this a cutting edge. The welding element blank is stamped with the cutting edge at the front into the assembly part to thereby form the through bore.

A crimp fitting comprises a metal tube wall that forms both a cylindrical tube portion and an adjacent annular O-ring channel portion. The tube wall has a first wall thickness along the cylindrical tube portion and a second wall thickness along at least part of the O-ring channel portion. The second wall thickness is less than the first wall thickness. The cylindrical tube portion and O-ring channel are configured and adapted to encircle a cylindrical end portion of a tube when such end portion of the tube is inserted into the fitting.

Embodiments of the present disclosure provide techniques and configurations for a rack assembly. In one embodiment, a tray to be disposed in a rack assembly may comprise a plurality of sleds with individual sleds including one or more compute nodes; and a networking element coupled with a sled of the plurality of sleds and configured to communicatively connect the sled to one or more other components of the rack assembly via an optical communication system. The optical communication system may include an external optical cable configured to communicatively connect the networking element with the rack assembly. Other embodiments may be described and/or claimed.
