摘要:
A golf ball includes a lattice reinforced layer, which is a layer made of at least two materials with different properties. The materials are interlocked with each other, where one material forms a grid with pores while the other material protrudes through the pores. In some embodiments, the lattice reinforced layer is manufactured using a shutoff molding technique so that the entire lattice reinforced layer is molded in the same mold. The lattice layer is provided to alter the properties of a layer, such as increasing the durability, toughness, or strength of the layer.

A golf ball includes a core made from a highly neutralized polymer that has been mixed with a hardness modifier. The modifier may be a process oil or a plasticizer. In particular, the modifier may be a naphthenic process oil, a paraffinic process oil, a phthalate plasticizer, a trimellitate plasticizer, an adipate plasticizer, a sebacate-based plasticizer, a maleate-based plasticizer, and blends thereof. Also disclosed is a method for manufacturing a golf ball that includes changing the hardness of a highly neutralized polymer core.

An over-indexed, optionally cross-linked thermoplastic polyurethane elastomer. Also, the method of making the elastomer, and articles, including golf balls, comprising the elastomer.
摘要:
A method of toughening thermoplastic polyurethane (TPU). The TPU is dipped into a urethane solution having a penetrating agent, then heated and dried for a period sufficient to toughen the surface. Also, articles such as golf balls having a toughened thermoplastic polyurethane surface. The toughened thermoplastic polyurethane surface is more scuff-resistant and has a greater strain-rate shear resistance than the TPU.

A fluid turbine comprises a turbine shroud and an optional ejector shroud. The turbine shroud and/or the ejector shroud are formed from a hard shell and a membrane. The hard shell forms a leading edge, a trailing edge, and an interior surface of the shroud. The membrane forms an exterior surface of the shroud. The resulting construction is lighter than previous turbine shrouds.

Example embodiments described herein relate an integral and/or multi-piece airfoil and a shrouded fluid turbine having the same. The airfoil can have a generally circumferential body extending circumferentially about a central axis, and can be referred to herein as a “ringed airfoil.” The airfoil can have a front portion defining a leading edge of the airfoil and a rear portion defining a trailing edge of the air foil. A cross-sectional thickness of the front portion can be non-uniform and vary along a mean camber line of the airfoil from the leading edge to a transition area. A cross-sectional thickness of the rear portion can be uniform and constant along the mean camber line of the airfoil from the transition area to the trailing edge of the airfoil.

A shrouded wind turbine comprises a shroud disposed about an impeller. The impeller surrounds a nacelle body which is shaped to enhance smooth flow of wind through the impeller. Some embodiments include an inlet and an outlet in the nacelle body, allowing airflow through an interior cavity. Other nacelle bodies may be tapered, flared, include mixing lobes around a trailing edge, or may have other shapes that enhance fluid flow. Some nacelle bodies include an annular groove that promotes flow attachment. Maintaining airflow attachment to the nacelle body within the turbine increases the energy generation capacity of the wind turbine.
