Putters include a putter body having a ball striking face member made of a material having a first hardness characteristic. A cavity is defined in the putter body behind the ball striking face member, and plural openings are defined in the ball striking face member extending rearward with respect to the ball striking face member and into the cavity. A polymeric material at least partially fills the openings and the cavity, wherein the polymeric material has a second hardness characteristic that is softer than the first hardness characteristic. The ball striking face member and the polymeric material exposed in at least some of the openings provide a ball striking surface of the putter. The ball striking surface may include grooves or scorelines to affect the launch angle, spin, and/or roll of the ball during a putt. Methods for making such putter devices also are described.

A method for manufacturing a fluid power transmission includes a first step of assembling a blade/core provisional assembly having a plurality of blades movably linked to a core, involving aligning the plurality of blades on a blade alignment jig, laying the core over a group of blades while extending a projecting piece provided on each blade through a latching hole provided in the core, and bending an extremity part of the projecting piece thus preventing the projecting piece from coming out of the latching hole, a second step of setting the blade/core provisional assembly at a predetermined position on an inside face of the shell, and a third step of carrying out brazing between the projecting piece and the latching hole and between the blade and the shell. Such method provides a high quality impeller of a fluid power transmission by joining a shell, a blade, and a core.

A composite clip for attaching decking. The clip includes a bottom and a top. The bottom is made of a first material. The top is made of a second material. The first material of the bottom is different than the second material of the top. The first material of the bottom engages in the second material of the top during manufacturing so as to attach the bottom to the top and form the gangable composite clip without a need for any other means to attach the bottom to the top.

A scaffold includes a radiopaque marker connected to a strut. The marker is retained within the strut by a head at one or both ends. The marker is attached to the strut by a process that includes forming a rivet from a radiopaque bead and attaching the rivet to the marker including deforming the rivet to enhance resistance to dislodgement during crimping or balloon expansion. The strut has a thickness of about 100 microns.

Various embodiments of stents with radiopaque markers arranged in patterns are described herein.

A cap for use in covering a portion of a fastener protruding from a surface is provided. The portion includes threads. The cap includes an interior, a base that at least partially delimits the interior, a threaded receptacle on the interior configured to threadably engage the portion of the fastener, and a seal coupled to the base to engage the surface.

The invention provides an article of manufacture, and methods of designing and making the article. The article permits or prohibits waves of energy, especially photonic/electromagnetic energy, to propagate through it, depending on the energy band gaps built into it. The structure of the article may be reduced to a pattern of points having a hyperuniform distribution. The point-pattern may exhibit a crystalline symmetry, a quasicrystalline symmetry or may be aperiodic. In some embodiments, the point pattern exhibits no long-range order. Preferably, the point-pattern is isotropic. In all embodiments, the article has a complete, TE- and TM-optimized band-gap. The extraordinary transmission phenomena found in the disordered hyperuniform photonic structures of the invention find use in optical micro-circuitry (all-optical, electronic or thermal switching of the transmission), near-field optical probing, thermophotovoltaics, and energy-efficient incandescent sources.

A housing component, for example a housing which accommodates electronics, such as a transmission control has a plurality of feedthroughs and a flatness zone. The housing component has a recess area in the region of the flatness zone. The housing component is reinforced through the recess and the flatness zone, which is disposed in the region of the recess, has a deviation from flatness of 0.1 millimeter (mm), for example in the range of 0.005 mm to 0.02 mm per 10 mm length.

A device is provided for the early detection of crack formations in work pieces or in components that are subjected to mechanical loading. Wherein in the region of at least one surface at risk of cracking there is arranged at least one testing chamber that is formed by a generative process of manufacturing the work piece or a portion of a work piece and to which a testing medium under pressure is admitted. Either a pressure sensor for determining a drop in pressure resulting from a crack formation of the work piece is connected to the testing chamber or a gas sensor that can also react to a testing medium escaping from the testing chamber in the event of crack formation is arranged in the vicinity of the testing chamber.
