A pad is disclosed that includes first and second outer layers. The outer layers include a plurality of channels at least partially filled with shear-thickening fluid. A shear layer is positioned between the first and second outer layers. The first and second outer layers may include first and second sheets that are bonded to one another in bonded portions and not bonded to one another in non-bonded portions such that the channels are defined by the non-bonded portions. The bonded portions may be perforated to facilitate air flow. The shear layer includes a lattice structure such as a plurality of rods extending between the first and second outer layers and oriented at a non-perpendicular angle to the outer layers. The rods themselves may be filled with shear-thickening fluid. The channels in the outer layers are criss-crossed to form a lattice or network in the plane of the outer layers.

Described herein are methods of improving the durability of concrete by the infusion of the concrete with a low-viscosity oligomeric solution, and subsequent curing of the oligomeric solution to form a high toughness polymer. Also described herein are compositions containing concrete and high toughness polymers, and formed articles made from concrete and high toughness polymers. The methods and compositions are useful for improving the durability of concrete roads and structures, as well as the durability of repairs to concrete roads.

A sulky includes a frame having a cross-member and a pair of shafts spaced from each other and extending from the cross-member forwardly along an axis. A first wheel support and a second wheel support each rotatably extend downwardly from the frame and each engage wheels, respectively. Each of the first and second wheel supports includes an adjustment feature defining a plurality of adjustment positions. The wheels are engaged with the first and second wheel supports, respectively, and are independently adjustable relative to the first and second wheel supports, respectively, to any of the adjustment positions. The plurality of adjustment positions of the first and second wheel supports are located along lines generally extending rearwardly along the axis and upwardly relative to the axis.

A ball catching and delivery head including a frame and a base for a lacrosse stick is provided. In addition to a socket for receiving a handle, the base includes a cavity for receiving a flexible cartridge and also trusses laterally located relative to the base that terminally connect with the frame and the base. The frame is vertically flexible relative to the base and the extent to which the frame is so flexible is dependent upon the cartridge flexibility and compressibility. The trusses prevent lateral movements of the frame relative to the base. Different cartridges made of different materials may be substituted for one another to achieve different flexing characteristics.

A handle for sports equipment such as a lacrosse or hockey stick including cushioning and grip ribs. In one embodiment, the shaft of the handle defines one or more regions of reduced diameter or thickness such as, in one embodiment, a plurality of elongate longitudinal grooves extending around the periphery thereof in spaced-apart relationship. Interior cushioning ribs are defined in the region of the grooves by a layer of cover or coating material which is applied to the surface of the shaft and fills the grooves. In another embodiment, the shaft includes tapered regions in the shaft and the layer of cover or coating material fills the tapered regions to define cushioning ribs.

The bat of the present invention has a barrel with a thinner outer shell in compressive and/or adhesive engagement with an insert laminate comprised of one or more pieces of a thin metallic (preferably titanium) sheet (or foil) and one or more sheets of a composite material. The titanium portion of the insert laminate may be on the inner-most portion of the insert, may be on the outer-most portion of the laminate, or may be in the interior of the laminate (that is, with one or more sheets of composite material on either side of it). Alternatively, the bat may simply be provided with only a titanium insert. In yet another set of embodiments, the titanium sheet may be replaced by another suitable metallic sheet. In all embodiments, the reinforcing sleeve allows the barrel portion to deflect farther when impacted by an object such as a ball without detrimental yielding (denting) and increases the rate of return of the barrel wall.
