Abstract: A sub-floor assembly having sub-floor panels that are adapted to be integrally overlapped while providing clearance for channel sections when the floor deflects under load. Clearance for the channel sections may be achieved by providing pockets in an upper layer of a first sub-floor panel in the area where the channel sections engage a second sub-floor panel with which the first sub-floor panel is in overlapping engagement.

Abstract: A floor support assembly including first and second subfloors is disclosed. The first subfloor is supported over a substrate by a plurality of pads. Each pad is housed in a corresponding recess formed in the first subfloor. Each recess includes a ridge that is in contact only with its respective pad when the floor is in a lightly loaded position. In a more aggressively athletically loaded state, the pad contacts the ridge and a portion of the top of the recess. In a non-athletic fully loaded state, the first subfloor plate near the load rests on the substrate. The second subfloor is located above the first subfloor and is supported by the first subfloor. A method of installing the same is also disclosed.

Abstract: A recovery plant for recovery of a gaseous component, such as carbon dioxide, from a process gas, such as the exhaust from a combustion turbine, has an absorber (110) employing a lean solvent (126) in an upper section of the absorber and a semi-lean solvent (172) in a lower section of the absorber. A regenerator (120) extracts the gaseous component from the rich solvent (117) thereby producing a regenerated lean solvent (126) and a semi-lean solvent (127). A solvent flow control element (170) combines at least a part of the semi-rich solvent (118) from the upper section of the absorber with the semi-lean solvent (127) from the regenerator to form a mixed solvent (171), and a cooler (112) cools the mixed solvent that is subsequently fed into the lower section of the absorber (110). By cooling the mixed solvent prior to entry into the absorber, the thermal energy required to remove the carbon dioxide from the exhaust gas can be reduced.

Abstract: A topocompositional image of an inanimate object or surface can be generated that comprises data that relates to a topographical image, data that relates to a chemical compositional image, and combining such topographical and chemical compositional data to form a composite image. Conceptually a laser or other suitable imaging source that functions to induce both topographical and chemical compositional data directs a laser beam into a scanning optics source. The scanning optics source directs an active beam to a point on a surface. A sensor subsequently collects data and information from the surface by receiving the reflection or deflection of the active beams in order to provide position, chemical compositional and topographical data that represent the interaction of the active beam with a point. Position data, chemical compositional data and topographical data are transmitted along individual feeds to a data analysis component where they are analyzed and combined in order to generate a composite image.

Abstract: The invention includes a subfloor assembly for supporting a floor surface on a substrate. The subfloor assembly includes a plurality of plate members extending in parallel relation along the substrate, with a space formed between adjacent plate members. A plurality of sleeper members extending longitudinally along the substrate, and are located in the spaces between adjacent plate members. First resilient members are positioned on the upper surface of each of said plate members, and second resilient members are positioned below the lower surface of each of said sleeper members. The floor surface is attached to an upper surface of said sleeper members. The second resilient members are preferably more compressible than the first resilient members. The subfloor assembly also preferable has a plurality of brackets that limit upper movement of the sleeper members but permit downward movement of the sleeper members.

Abstract: A resilient portable sports floor system, more particularly one which is formed of a plurality of components which may be easily interconnected to form an integrated sports surface. The floor system includes a plurality of floor panels, each floor panel including a playing surface and four sides, at least one floor panel attachment mechanisms on each side of the floor panel, and a drive mechanism attached to each of said floor panels and attached to a floor panel attachment mechanism, the drive mechanism including a threaded rod. When the threaded rod is rotated it moves the drive mechanism with respect to the floor panel.

Abstract: The present invention provides a subfloor system for placement over a substrate. The subfloor consists of a base, a resilient pad, an upper member, and brackets. The resilient pad is positioned on the base, preferably within an elongated slot formed in the upper surface of the base. The upper member is operably connected to the top surface of the resilient pad. The upper member has a projection and two shoulders. The brackets have an upper and lower tab and are secured to the base and to the upper member. The lower tab is adapted to fit within the base and the upper tab rests on the corresponding shoulder of the upper member. When under load, the resilient pad compresses thereby causing the upper member to move towards the base. The brackets, however, limit vertical movement of the upper member relative to the base. The invention also includes a method of forming a resilient sports floor employing such a subfloor system.

Abstract: A resilient pad for resiliently supporting a floor on a substrate is disclosed. The resilient pad includes a resilient inner element and an outer element which surrounds the inner element. The outer element is made of a material which is of higher durometer than the inner element, and is lower in profile than the inner element. Preferably the outer element is non-resilient. Under normal loads applied to the floor, the softer inner element contacts the substrate, resulting in desirable floor response characteristics. Under heavy loading, the harder outer element comes into contact with the substrate, thus supporting the floor and preventing damage to the inner element.

Abstract: The invention is a resilient pad for placement under a floor system. The pad is made up of a base and a plurality of pad elements spaced longitudinally apart and attached to the base. At least one of the pad elements has a thickness which is greater than another of the pad elements. Because the pad elements have different thicknesses, the resilient pad provides desirable response and shock-absorption characteristics over a wide range of applied loads. Hence, the resilient pad is especially suitable for use with sports floors and the like.
