A lacrosse head including a spine element that is at least partially embedded or encapsulated in a base and sidewalls of the lacrosse head. The spine element can terminate short of a scoop of the lacrosse head. Where the lacrosse sidewalls are of an open frame construction and include a non-string hole, the spine element can define a spine element hole that is aligned with the non-string hole. The spine element can also include a transverse element that spans from an upper rail to a lower rail of the sidewalls adjacent a cross member of the sidewalls. The base and sidewalls can include viewing apertures through which some of the spine element can be viewed, while other parts of the spine element remain concealed. The spine element can be constructed from one plastic, while the remainder of the head can be constructed from a different plastic.

A building connection between a substantially vertical wall stud and a substantially horizontal bridging member, using a separate and distinct bridging connector that attaches the wall stud to the bridging member. The wall stud is typically one of several sequentially-arranged, cold-formed steel studs in the frame of a building wall. The bridging member is typically a separate cold-formed steel member that interfaces with and spans a plurality of wall studs.

A flame retardant bedding article comprises a hydroentangled flame retardant nonwoven component, and more specifically, a bedding article such as a mattress, pillow cover or mattress pad, comprising a structurally stable, flame retardant nonwoven component. The component comprises at least two layers that have a synergistic relationship so as to maintain the structural integrity of the bedding article upon burning.

A method for joining a first part formed of an aluminum material to a second part formed of a steel material by metal inert gas welding and cold metal transfer is provided. An aluminum filler material forms a fillet joint between the parts and provides a structure for automotive body applications, such an aluminum bumper extrusion joined to a steel crush box connection. The first part includes a notch for hiding the start and end of the joint. A transition plate formed of a mixture of aluminum material and steel material can be disposed between the first part and the second part to provide the notch. The second part can include a mechanical fastener further joining the parts together. In another embodiment, the second part includes a plurality of dimples and is welded to the first part along the dimples.

A piston ring formed of cast iron provides improved machinability and exceptional performance and minimum costs. The cast iron includes 2.2 to 2.9 wt. % carbon, 3.2 to 4.2 wt. % silicon, 0.75 to 1.25 wt. % copper, 1.0 to 1.5 wt. % manganese, 0.09 to 0.15 wt. % sulfur, not greater than 0.2 wt. % phosphorous, and an average carbon equivalent of 3.8. The cast iron preferably includes a matrix of martensite with MnS and carbides dispersed therein. The matrix is also preferably free of ferrite, austenite, and steadite. The cast iron is formed by casting, autenitizing, quenching, and tempering the alloy.

Disclosed is a highly safe battery separator, in particular a separator for a lithium ion secondary battery, which reduces internal resistance, achieves good ionic conductivity, prevents passing of electrode active materials, and also prevents electrical short circuit by controlling deposition of lithium metal (dendrite). Also disclosed is a means for stably producing the battery separator with high productivity. Specifically disclosed are: a battery separator which is composed of a porous polyolefin sheet that is formed from a group of polyolefin nanofilaments that have an average filament diameter of less than 1 μm and a filament size distribution of 0.2 or less; and a means for producing the battery separator.

A composition comprising lignin compounds possessing 8-30 (or 5-15 or 8-12) phenyl rings interconnected by ether and alkylene linkages and containing hydroxy and / or methoxy groups attached to said phenyl rings, wherein said composition possesses a glass transition temperature of 80-100° C. (or 95-98° C.) and a degree of substitution (DS) of carboxylic acid groups per phenyl ring of at least 0.5 and a DS of methoxy groups per phenyl ring of no more than 1.2, 1.1, or 1.0, wherein at least 90 wt % of said lignin compounds has a molecular weight within a range of 500-5000 g / mol, 1500-3000 g / mol, or 2000-2500 g / mol and / or wherein the molecular weight distribution of the lignin compounds is characterized by a polydispersity index of 1.0-1.5, 1.0-1.4, or 1.0-1.3, and wherein other lignin compounds not possessing the above characteristics are not present. Methods for producing the lignin extract and lignin copolymers and blends produced therefrom are also described.

Systems and / or methods of waste disposal use human-made caverns that are constructed within deep geological formations. A given human-made cavern may be constructed by first drilling out a vertical wellbore to a deep geological formation. Then a bottom portion of the vertical wellbore is jet drilled using an abrasive jetting fluid to form a launch chamber of void volume, that is sized to fit a reaming tool in its deployed open configuration. A reaming tool, in a closed configuration, is then inserted into the vertical wellbore for landing in the launch chamber. The reaming tool is then deployed into its open configuration while in the launch chamber. Reaming operations then occur from the launch chamber directed downwards within the deep geological formation, forming a given human-made cavern. The newly formed human-made cavern may be conditioned and / or configured for receiving amounts of the waste for long-term disposal and / or storage.
