Abstract: The present invention relates to a drum stencil printing system for reliably and automatically printing materials on the inside of a concave surface. The drum stencil printing system includes a pliable drum stencil secured in place by a stencil spring. As the printhead applies radial pressure to the drum stencil, the portion of the stencil in contact with the printhead is deflected to make contact with the container sidewall. When the printhead rotates, the portion of the stencil contacting the container sidewall also rotates to match the nozzle of the printhead. After printing is complete, the printhead retracts, and the pliable stencil is returned to its undeflected position, breaking contact between the stencil and the container, and protecting the printed material from being rubbed or worn off of the container.

Abstract: Fishing tackle is coated with nanostructured material to modify and improve the performance. The fishing tackle includes a fishing rod which is coated adjacent a first end section, in a middle section, adjacent a second end section, or over an entire surface to improve the action, power or any performance characteristic and/or decrease weight, The fishing tackle includes a fishing reel which is coated in whole or part with a nanostructured material to improve strength, corrosion resistance or performance and/or decrease weight. The fishing tackle includes a fishing rod guide which is coated with a nanostructured material to improve performance and/or decrease weight. The area of coverage and thickness of the material coated on each component of the fishing tackle can be changed, as stipulated by design criterion.

Abstract: A bicycle comprises a frame. A portion of the frame includes a substrate and a layer of nano-crystalline material extending over at least a portion of the substrate. A conductive interface is disposed between the substrate and layer of nano-crystalline material for improved adhesion of the layer of nano-crystalline material to the substrate and improved impact performance of the frame portion.

Abstract: A sports bat, such as a baseball or softball bat, is electro-deposited with a nanostructured metal. Bats made from aluminum alloys or other metals may be electro-deposited with varying thicknesses of nanostructured metals such as nickel, nickel iron, cobalt phosphorous, or similar materials. The bat substrate alloy can be any metal or alloy. The coating may be done using an electro-deposition process.

Abstract: A sports article includes a portion that includes a nanostructured material. The nanostructured material includes a metal, and the nanostructured material has an average grain size that is in the range of 2 nm to 5,000 nm, a yield strength that is in the range of 200 MPa to 2,750 MPa, and a hardness that is in the range of 100 Vickers to 2,000 Vickers. The sports article can be any of a variety of sports equipment and associated components, such as a golf club, a baseball bat, a softball bat, a lacrosse stick, or a hockey stick.

Abstract: A metalwood coated at least partially with a nanostructure material offer improved performance over existing golf club heads made from a combination of steel and titanium alloys or composite club heads made in part or wholly from fiber-reinforced plastics (FRPs) and metallic sub-components. The components of the metalwood may be coated with variable thicknesses of electro-deposited nanostructure metals and alloys.

Abstract: A set of golf shafts is disclosed. The set comprises a plurality of shafts that decrease in length along the set. Each shaft includes a reverse taper section disposed a distance from the tip section on each shaft. The distance of the reverse taper section varies along a number of shafts as the shaft length decreases.A golf club shaft is disclosed. The shaft includes a tip section, lower section, and an upper section. The tip section connects with a golf club head. The lower section includes a tapered section and a reverse taper section. The tapered section extends from the tip section. The tapered section increases in diameter in a direction away from the tip section. The reverse taper section extends between the tapered section and the upper section. The reverse taper section has a diameter that decreases in a direction away from the tip section. The shaft further includes a resilient plug wedged inside the shaft.
