Abstract: A modular overflow spout that covers a tank outlet comprising an overflow cover removably attached to a curb assembly. The overflow cover includes a canopy and a cover plate. The curb assembly comprises an outer curb having a lower curb flange that can be incorporated into the tank outlet and an upper curb flange that is positioned above the tank outlet. An inner curb is attached to the outer curb and can be incorporated into the tank outlet with the inner curb. The modularity allows the outer curb to be adjustable within the outlet so that the angle of the upper curb flange is conducive for attachment of the cover plate on the overflow cover after the curb assembly is incorporated into the tank roof.

Abstract: The invention concerns a floor-to-wall joint connection “BearStop” device for providing both a water-tight seal, as well as load-bearing and flexibility between two closely abutting or adjacent structures, such as the wall and foundation of a storage tank. Embodiments also provide motion or sliding capabilities to accommodate expansion and contraction in the joint area between the wall and the foundation. A knee section provides a testing channel usable for testing the integrity of the seal.

Abstract: A thermal energy storage installation including a thermal energy storage tank and a spider diffuser system mounted in said tank. The TES tank comprises an outer wall having a generally cylindrical inner surface surrounding a hollow internal space in the tank. The spider diffuser system comprises a centrally disposed manifold structure that is disposed in vertically spaced relationship relative to a thermocline formed in a temperature stratifiable liquid in the space during operation of the tank. The manifold structure has an internal chamber and includes an opening for introduction of a said liquid into the chamber or discharge of a said liquid from the chamber. The spider diffuser system also includes a diffuser pipe assembly comprising a plurality of elongated diffuser legs. Each of the legs is attached to the manifold structure so as to extend generally radially outwardly from the structure and toward the inner surface of the tank.
