An arena apparatus for staging a sport with at least one athlete is provided. The arena apparatus includes a floor having a perimeter; and at least one wall at the perimeter and extending upwardly and outwardly from the floor at an angle greater than or equal to fifteen degrees measured from an axis perpendicular to the floor, wherein the angle of the wall prevents the athlete from standing on the wall.

A perimeter frame used in a construction of floors or roofs of buildings, including three superior radial sub-frames, three inferior radial sub-frames, and six non-perpendicularly interconnecting top hat sub-frames, wherein each superior radial sub-frame is located between a pair of inferior radial sub-frames such that there is a 60° angle between the first and second longitudinal axes of any two adjacent radial sub-frames, and wherein the innermost blunt end portions of the superior radial sub-frames are interconnected to define a primary hexagon structure at a centre of the perimeter frame, and the innermost blunt end portions of the inferior radial sub-frames are connected to a converging region of adjoining surfaces of each adjacent pair of superior radial sub-frames to define a secondary hexagon structure around the primary hexagon structure, and wherein the overhang end portions and the outermost blunt end portions define six corners of a hexagonal perimeter frame.

The innovation relates to a pool covering system that is usable as a flooring surface. The pool covering system includes brackets and support beams spanning the pool opening. The beams provide structural support to cross members and flooring placed on top of the beams. The pool covering system does not require significant drainage of the pool and does not damage the pool structure during installation and use.

A semiconductor processing system and a method for assembling such a system in a room of a semiconductor fabrication plant. The system comprises an equipment module and a pedestal. The equipment module may be movable over the pedestal to bring the equipment module in an end position and may have a plurality of stop surfaces. The method comprises placing the pedestal in the room, placing two stops on the pedestal and positioning the two stops relative to reference elements in the room, and connecting the positioned stops to the pedestal so that the positions thereof in the X-direction and Y-direction are fixed. The equipment module may be moved over the pedestal until the stop surfaces of the equipment module abut against the stops so as to position the equipment module in the X-direction and Y-direction relative to the reference elements.

A support stand (2) and a foundation system (1) for a building comprising the support stand (2) attachable to a structural beam (3) in which the support stand (2) comprises a pedestal (6) and a beam carrier (7) mounted on the pedestal (6) wherein the beam carrier (7) comprises a wingnut construction defining at least one substantially vertical wing (19,33) connectable with a structural beam (3).
