Abstract: An exemplary stair nosing assembly comprises an elongated base, a plate adhered to the base, and a cover temporarily covering the base and the plate. The base has at least one anchor portion extending downwardly from the upper portion for attaching to a lip of a tread pan and/or embedding in a concrete tread. The plate can have various features to enhance traction and visibility. The cover has front and rear lips that engage with front and rear edges of the base, and a weakened region adjacent the rear lip. When the assembly is embedded in a concrete tread, the cover is configured to fracture at the weakened region when the front lip of the cover is lifted upward from the base, leaving the rear lip remaining embedded in the concrete and allowing the rest of the cover to be removed to expose upper surfaces of the base and plate.

Abstract: The end of a transversely extending beam is joined to a wall structure by a self-releasing structural assembly. It has a first portion anchored to the wall. A second, fireproof and non-thermally degradable portion of the assembly sticks out from the wall. The assembly has a thermally degradable member mated to the second portion of the structural assembly. Both portions have slots for accepting beam fasteners. The beam fasteners squeeze the end of the beam, the support bracket seat, and the consumable, thermally degradable member in compression. When exposed to heat or flame the consumable, thermally degradable member softens, releasing the tension in the beam end fasteners, and releasing the compression in the structural sandwich of parts. The end of the beam is then able to translate away from the wall structure. The consumable member can be inspected without removing the beam end from the seat.

Abstract: A data center module is a data center that can be prefabricated using generally standardized off-the-shelf components, and quickly assembled on a collocation site where a shared central facility is provided. The data center module is typically configured to be deployed with other identical data center modules around the central facility both in side-to-side and/or in back-to-back juxtapositions, typically without the need for interleaving space between adjacent modules in order to maximize real estate use. Each data center module typically comprises harden party walls, several floors for accommodating all the necessary electrical and cooling subsystems and for accommodating all the computing machinery (e.g. servers). Though all the data center modules share similar physical configuration, each data center module can be independently customized and operated to accommodate different needs.

Abstract: Liner plates of mild steel layered over with chromium carbide are provided with a bi-planar spacer clip also acting as a lifting eye on the top surfaces thereof and fasteners such as bolts or studs extending from the exposed planar surface of the mild steel layer. A chain and hook arrangement is used to deliver and locate each liner plate adjacent a wall upon which the liner plates are to be mounted in vertically stacked relationship. The clips serve as spacers between vertically stacked liner plates and the fasteners extend through pre-formed holes in the wall of the delivery structure. The clips have a notched base portion which receives a weld bead running along the top exposed edge of only the mild steel layer. The clips are left in place after installation and are gradually worn away by ore traveling through the delivery structure.
