A cell for a stormwater management system adapted for retaining or detaining stormwater. The cell comprises a body portion and an internal region. The body portion comprises a plurality of corner columns spaced from each other, a plurality of wall portions, and a window. Each wall portion extends from one of the corner columns to another of the corner columns. Each wall portion comprises an inner surface and an outer surface. The inner surface of each wall portion is curved. The window is through at least one of the wall portions. The window is adapted to permit passage of stormwater into and out of the internal region of the cell.

A mold set for manufacturing interlocking construction blocks comprising a modular family molds and connecting side walls. The molds may be configured to create assembled female molds that may be filled with fluid cement, which can be removed from the female molds with corresponding male molds. Each assembled female mold may comprise one or more interlocking sections that allow the resulting blocks to interlock in three directions along three axes, including a left/right axis, a front/back axis, and an up/down axis. Each block comprises a specific geometry that allows all blocks in the family to interlock in a woven pattern that not only locks the blocks in place but also allows even distribution of structural weights. The disclosed modular mold sets allow blocks to be manufactured in different sizes to conform to any building code requirement and to create wall lengths to a one-inch measurement.

The present invention relates to a self-pouring mold system which ensures uniformity of a material by laterally pouring concrete into a mold installed on a side of a wall structure and minimizing a fall head generated when the concrete is poured to prevent bleeding, thereby ensuring uniformity of a fire-proofing material and adjusting a required fire-proofing coating thickness, and a method of fire-proofing, repairing, and reinforcing using the same.

A high temperature fastener including a bolt and a nut, where the bolt and the nut are constructed of an aluminum oxide ceramic material reinforced with silicon-carbide crystal whiskers or silicon nitride.

A method and system for manufacturing and using a self-supporting structure in processing unit for adsorption or catalytic processes. The self-supporting structure has greater than 50% by weight of the active material in the self-supporting structure to provide an open-celled structure providing access to the active material. The self-supporting structures, which may be disposed in a processing unit, may be used in swing adsorption processes and other processes to enhance the recovery of hydrocarbons.

A system of retaining wall blocks, a method of assembling a retaining wall block assembly, and a mold for manufacturing retaining wall blocks having adjustable engagement configurations.

A method and apparatus for forming a part having a cavity with a complex contour is presented. The molding apparatus comprises a mold cavity and a molding insert. The mold cavity is formed by a first mold portion and a second mold portion. The molding insert is within the mold cavity, wherein the molding insert has a forming surface, and wherein the molding insert is configured to move in more than one direction relative to the first mold portion
