Abstract: A method of providing a removable building structure containing computing equipment. The method comprises providing an array of cabinets. The cabinets are formed from vertical support pillars wherein at least some of the vertical support pillars are hollow and have apertures formed along their length and arranged to enable air flow through the posts to control the temperature within the building. A roof is supported by using the array of cabinets as a modular constructional element of the building structure to provide support providing outer walls for the building. Computing equipment is placed in the cabinets.

Abstract: A grommet closure device for sealing a cable opening in a raised floor, the device comprising: a frame structure defining an aperture; and a sealing member having flexible sealing means attached along its length in cantilever fashion, the sealing member being arranged to span the aperture such that unattached ends of the sealing means can extend away from the sealing member and rest on the frame structure, thereby covering the aperture.

Abstract: The present invention relates to a floor gland for covering an access hole provided in a raised floor structure to allow cabling to pass through the floor structure. A problem with this arrangement is that cooling air passing underneath the raised floor structure can escape through the access hole. A floor gland is provided to fit into the access hole, the floor gland having sealing means that are secured to a sealing member mounted across the open area of the floor gland at a distance from the edges of the access hole such that the sealing means extend out from the sealing member towards the edges, thereby effectively sealing the access hole to prevent the passage of cooling air.

Abstract: A fastener for fixing of a component to a body, such as a mounting surface or post, and which is designed to act as a one-piece component, comprises a head portion and a tail portion joined together by a longitudinally-extending body having a smaller cross-sectional area than both the head portion and the tail portion, and a deformable shoulder extending outwardly from the body to the tail portion or head portion, wherein the head portion has a greater cross-sectional area than the tail portion and the tail portion is non-circular in cross-section.

Abstract: A shelf (1) for a cabinet. The shelf has a hinged flap (7,8) at either end. When the shelf is lifted, the flaps pivot downwardly under gravity to cause an effective reduction in the width of the shelf allowing the shelf to be removed between two front posts of the cabinet.
