Abstract: A process for removing silica and reducing total hardness of a natural or waste water containing silica and scale-forming ions comprises adding (i) magnesium hydroxide or a precursor of magnesium hydroxide and (ii) a soluble aluminate compound or a precursor of aluminate to said water while maintaining the pH of said stream at pH>8 to produce a layered double hydroxide in situ, wherein the layered double hydroxide contains the scale-forming ions in a lattice of the layered double hydroxide and silica is incorporated in the lattice of the layered double hydroxide as an interlayer anion and/or bound by the layered double hydroxide via one or more binding modes, wherein the process further comprises a recycling and regeneration step and/or a hydroxide addition step.

Abstract: A process for simultaneously removing silica and reducing total hardness of a natural or waste water containing silica and scale-forming ions is described. The process comprises adding (i) magnesium hydroxide or a precursor of magnesium hydroxide and (ii) a soluble aluminate compound or a precursor of aluminate to said water while maintaining the pH of said stream at pH>8 to produce a layered double hydroxide in situ, wherein the layered double hydroxide contains the scale-forming ions in a lattice of the layered double hydroxide and silica is incorporated in the lattice of the layered double hydroxide as an interlayer anion and/or bound by the layered double hydroxide via one or more binding modes.

Abstract: A ball bat includes a barrel portion, a handle portion, and a joint connecting the handle portion to the barrel portion. In some embodiments, the joint includes a releasable connector configured to releasably connect the barrel portion to the handle portion. In some embodiments, the joint includes two releasable connectors to releasably connect the barrel portion to the handle portion. The ball bat may include a flexible rod element positioned between the two releasable connectors. The rod element may include an elastomeric material. In some embodiments, the ball bat may further include a safety connector between the barrel portion and the handle portion or a releasable connector may include a threaded connection to resist release of the releasable connector. In some embodiments, the joint may include a rotatable element for adjusting flex.

Abstract: A method of making a ball bat may include forming a bat frame with a handle and an inner barrel structure, providing spacer elements extending radially outwardly from the inner barrel structure, and forming a barrel shell having a main barrel and a tapered section. An inner diameter in the tapered section may be equal to an outer diameter of a first one of the spacer elements. The method may include mechanically locking the barrel shell to the bat frame by passing the handle through the barrel shell and moving the barrel shell toward the inner barrel structure until the barrel shell contacts the first one of the spacer elements. A gap is maintained between an outer diameter of the inner barrel structure and the barrel shell. The barrel shell may deflect during a hit to create a trampoline effect, while the inner barrel structure limits the deflection.

Abstract: An end-cap assembly for a ball bat or other sporting-good implement includes one or more removable weights, so that the weight of the end cap—and of the ball bat—may be adjusted.

Abstract: A ball bat includes a handle, a barrel attached to or continuous with the handle, and a tamper-evident section positioned in the barrel. The tamper-evident section may include a layer of foam material or another suitable material positioned within a wall of the barrel between an inwardly facing surface and an outer layer of the wall. The outer layer of the wall may be positioned to deform to indicate a condition of the tamper-evident section. In some embodiments, the wall is formed from a composite material. In other embodiments, the wall may include a metal alloy material and the outer layer may include a composite material. The foam material may have a compression value greater than that of a softball.

Abstract: A grip for a sporting-good implement, such as a ball bat, includes a knob portion configured to be positioned around a knob and a handle portion adjacent to the knob portion. The knob portion may have a first thickness and the handle portion may have a second thickness different from the first thickness. The knob portion may have a first degree of hardness and the handle portion may have a second degree of hardness. In some embodiments, a sporting-good implement may include a handle with a recessed region. The recessed region may be formed between the knob and an edge on the handle. The recessed region may be configured to receive a handle portion of a grip element such that the grip element and the handle are generally flush near the edge.

Abstract: A grip or cover for a sporting-good implement, such as a ball bat, includes a knob portion generally positioned around a knob of the bat, and a handle portion generally positioned around a handle region of the bat. The handle portion may be formed from a material that is harder than the knob portion. The knob or part of the handle region may include a grooved surface to engage with the grip to help retain the grip to the bat. In some embodiments, a method of manufacturing a bat or other sporting-good implement includes positioning a portion of a handle or knob in a mold and providing an elastomer in the mold to cover the portion of the handle and knob. In some embodiments, different portions of the elastomer may be cured at different temperatures to provide different material properties, such as different degrees of hardness, to those portions.
