A wear panel for mining and materials handling applications is provided. The wear panel includes a housing matrix (1) with a top surface (2), a bottom surface (3) opposite the top surface (2) and at least one cavity (4) with cavity walls (5). The cavity (4) extends through the top surface (2) and the bottom surface (3). The wear panel also includes at least one wear-resistant member (6) with a preformed shape. The at least one wear-resistant member (6) has a top surface (7) and a bottom surface (8) opposite the top surface (7). The wear-resistant members (6) are disposed in the cavity (4) and are locked into place by their preformed shape and the cavity walls (5).

Methods of forming vias in substrates having at least one damage region extending from a first surface etching the at least one damage region of the substrate to form a via in the substrate, wherein the via extends through the thickness T of the substrate while the first surface of the substrate is masked. The mask is removed from the first surface of the substrate after etching and upon removal of the mask the first surface of the substrate has a surface roughness (Rq) of about less than 1.0 nm.

A substrate based skin contact material formed from a hydrocolloid having a silicone based component extending over regions of the substrate surface. The adhesive is formed non-continuously over the substrate to provide areas devoid of adhesive to allow appreciable moisture transfer between the skin and substrate and improve the skin friendliness of the material during use and allow convenient removal with avoidance of skin irritation.

A corrugated sheet metal wall sheathing for resisting external excitations such as wind or earthquake of light-framed wall structures. The sheathing has sheet profile proportioned to insure the top flutes deform laterally and yield at the end of the flute before the onset of any failure mode. A transverse slot in included in each top flute and adjacent web of the sheathing and spaced at intervals along the length of the sheathing.

A method of producing a veneered element, including providing a substrate, applying a sub-layer on a surface of the substrate, applying a veneer layer on the sub-layer, and applying pressure to the veneer layer and/or the substrate, such that at least a portion of the sub-layer permeates through the veneer layer. Also, such a veneered element.

Curable prepregs possessing enhanced ability for the removal of gases from within prepregs and between prepreg plies in a prepreg layup prior to and/or during consolidation and curing. Each curable prepreg is a resin-impregnated, woven fabric that has been subjected to a treatment to create an array of openings in at least one major surface. Furthermore, the location of the openings is specific to the weave pattern of the fabric.

A system and method for producing a board product made from paper products that have a pre-scored facing in addition to a medium (sometimes called fluting). Conventional corrugated board may feature a cross-corrugated medium and one or more facing that have no score lines that are imprinted (at least prior to assembly with the corrugated medium). Such a conventional board product may be inferior because any score lines that are imprinted will damage the underlying corrugated medium in some manner. A breakdown in the strength of the underlying medium leads to poor precision when the eventual board product is scored, cut, and bent. A lack of precision in folding a board product is known as fishtailing as any articulated portion of the board product may not maintain a precise plane of articulation when bent. Hence, the articulated portion “fishtails” out of alignment. Having precisely located impression lines in register to underlying flutes of a medium ensures correct and precise articulation.

A stretch laminate and a method for reducing and/or preventing tearing in a stretch laminate, when the stretch laminate is stretched in a stretching direction, is disclosed. The stretch laminate has a perforation pattern. The perforation pattern has at least two columns. A first column has a plurality of pairs of perforations stacked one pair above the other pair. The perforations in each pair sloping in a first direction, and a first space separating one pair from the other pair. A second column has a plurality of pairs of perforations stacked one pair above the other pair. The perforations in each pair sloping in a second direction, and a second space separating one pair from the other pair. The first direction and the second direction may be different. A third space between the columns is no greater than the first or second space between perforation in the pair.

Some embodiments of present disclosure are directed to a micro-perforated glass or glass-ceramics laminate, comprising a first substrate laminated to a second substrate by a first polymer interlayer, wherein the first and the second substrates are independently selected from glass or glass-ceramics, and a plurality of micro-perforations, each of the plurality of micro-perforations extending through the first substrate, the first polymer interlayer, and the second substrate. Some embodiments are directed to methods of forming such micro-perforated glass or glass-ceramics laminates.
