Crane mat and method of manufacture

A crane mat is disclosed having a plurality of panels of lumber positioned in alternating transverse directions with respect to one another, where the top and bottom panels are oriented parallel to the direction of vehicular traffic. The top and bottom panels may include a plurality of spaced apart grooves extending longitudinally from a first longitudinal end of the crane mat to a second longitudinal end of the crane mat for enhancing traction of a vehicle when traversing across the crane mat by transporting rain or moisture off the mat, or for receiving mud or other debris. The crane mat may include a plurality of edge protectors positioned on respective sides of the crane mat to protect the crane mat from handling damage. In various embodiments, the crane mat may be manufactured using either softwood, hardwood, or any combination of softwood and hardwood.

SINGLE PASS CARPET-PRODUCTION METHOD AND CARPETS PREPARED USING SAME

A low-weight carpet or carpet tile and process for making the same, wherein the carpet or carpet tile comprises a facecloth having a plurality of face yarns tufted through a primary backing, a low-viscosity polyolefin coating layer applied to the primary backing, a reinforcing scrim layer, and an extruded polyolefin sheet. The top surface and bottom surface of the carpet tile are defined by the facecloth and either the extruded polyolefin sheet or the reinforcing scrim layer, respectively. The entire multi-layer web is then passed through a nip to compress the layers together, and the entire web is chilled before optionally being cut into tiles.

Multilayer coverings to protect surfaces from lightning strikes
11703034 · 2023-07-18 · ·

A multilayer protective covering can protect a surface from lightning strikes. The covering includes a bottom conductive layer affixed to the surface and having a first opening that is aligned with a grounding connection so that the grounding connection is exposed through first opening and not in contact with the bottom conductive layer. The covering also includes a dielectric layer affixed to the bottom conductive layer and having second opening aligned with the grounding connection so that the grounding connection is exposed through second opening and not in contact with the dielectric layer. The covering additionally includes a top conductive layer affixed to the dielectric layer and covering the grounding connection. The top conductive layer directs electrical current from a lightning strike on the surface to the grounding connection.
