Abstract: A wall system is disclosed involving wall panels of corrugated sheets as a stay-in-place forming system for concrete for building a shelter for protection from severe weather conditions, e.g., tornadoes, hurricanes, etc. The corrugated sheets are joined together, both in adjacent and opposing positions, forming a crevasse between the corrugated sheets into which concrete is poured. Each corrugated sheet has a horizontal reinforcement member rigidly attached to the internal side of the corrugated sheet wherein a horizontal reinforcement member is an L-shaped angle steel having a plurality of connecting holes on its horizontal element. A plurality of uniting rods are used to connect two opposing wall panels by inserting each end of the uniting rod into the connecting holes of opposing horizontal reinforcement members. A connecting bar assembly is used to more securely connect two adjacent wall panels.

Abstract: A system, panel and method are provided for constructing confinement cells such as jail and prison cells. The panels have a face plate and a corrugated sheet having holes for fluid concrete flow therethrough. The panels are designed to be interconnected to act as concrete forms, and the face plates have flanged side edges to minimize the presence of recesses therein. The face plates are preferably chemically treated to promote adherence to of the concrete thereto.

Abstract: An upright generally cylindrical bin is provided including a plurality of peripherally spaced upstanding structural members relatively anchored at their lower ends. Each of the structural members includes a horizontally elongated main wall member supported therefrom and extending vertically therealong and which projects outwardly from the structural member in opposite directions toward the peripherally adjacent structural members. Adjacent ends of adjacent main wall members are spaced apart and include bevelled end edges defining, together, an included angle greater than the angle between radial planes of the bin containing those end edges.

Abstract: A veil section of a hyperbolic natural draft cooling tower is constructed on a lintel beam in the form of a closed planar curve provided with anchors spaced about the perimeter of the lintel beam for facilitating connection to the lintel beam of upstanding peripherally spaced column sections between which preformed panels are attached to fill the spaces between the spaced columns. Once the panels are affixed to the columns, the latter, as well as the adjacent portions of the adjoining panels, are encased in a cementitious material such as concrete. Additional sections of columns and panels are erected above the initial veil section by the same process as the latter in order to complete the veil. Vertically adjacent veil sections are attached to one another by connection of the columns in end-to-end relationship.

Abstract: A wind driven electric power generator having a shroud arranged in a path of fluid flow. Within the shroud is disposed a stationary shaft supporting a wind generator assembly. The shroud can be the veil of a conventional cooling tower, with the wind generator assembly including a rotor connected to an electric generator arranged for converting rotary motion of the rotor to electrical energy, thus saving some of the energy created by the natural draft passing up the veil of the cooling tower. Space frame box trusses provided with airfoils provide lightweight arms for the rotor, with the rotor being arranged anywhere in the shroud. When a hyperbolic cooling tower veil is used as the shroud, the rotor will usually be positioned in the throat of the veil.
