Abstract: A rail (1) of U-shaped section is used as a casing for a bar of wood. The rail has barbs on the inner walls and ribs (4, 3) at the bottom. Tracks extend on the underside of the rail, the said tracks matching tracks on the mountings (2). The rail also has a horizontal support shelf on its outer side. The rail with bars of wood are secured with the aid of the mountings on an underfloor damaged by moisture whereas a material serving to isolate the underfloor is located on the shelves. The said material rests on two support shelves (5) pertaining to the rails and situated at some distance from one another. It is also possible for an insulating material to be placed on top of the isolating material (12, 14). A new flooring material is now fixed on top of the bars. At this stage the space between the underfloor and the isolating material brought about in this way is ventilated naturally or by force. The same method can be used to prevent radon rising through the underfloor from penetrating the premises above.

Abstract: A resilient wood floor for aerobic exercise. The boards of the floor are free to pivot in tongue and groove joints.

The lower part of the moulding has also at right angle going passages (5). The supports (4), shaped of the moulding on the either side, are used to carry plate-type material, which between two moldings shaped the ventilated space.

Abstract: A floor panel system for use in grain storage and drying bins is disclosed which uses modular perforated floor panels each of which is hemmed across the width of the panel at predetermined points along its length so that panels of various lengths can be provided readily by breaking standard panels along any appropriate selected hem. The hems also reinforce the panels. Each modular floor panel may have a complete hem at one end and a half hem or flange at the other end such that the panels can be readily aligned and interlocked end-to-end by inserting the half hem or flange of one panel into the full hem of a succeeding panel. A transverse clip may be used to hold together two abutted modular floor panels end-to-end and for reinforcing purposes where high floor loads are contemplated. Adjacent panels are abutted together along the sides and are held together by fitting the side lips into rails or support beams.

Abstract: A closely spaced array of modules forms an athletic playing surface characterized by a high degree of vertical compliance, an extreme resistance to lateral shear, and a high degree of uniformity of response. Each module has a laminated construction that includes a pair of stiffly resilient plates in a generally parallel, spaced relationship. One or more spacer plates and a plurality of resilient members are "sandwiched" between the plates. The lower plate is supported on a frame that allows it to flex in response to an applied force, typically the impact of a runner's foot on the upper plate. The spacer plate is configured, positioned, and secured to the upper and lower plates to mechanically couple them in a manner that, to a large degree, compensates for a non-uniformity of the deflection response of the module introduced by the frame support. The resilient members are selected and positioned to provide a substantially uniform deflection response at the upper plate.
