Abstract: An agricultural floor panel and system having a design for improved strength and cleaning is described. The floor panel is designed for support on at least two cross beams. The floor panel has two opposing edges, each edge having a plurality of flanges for supporting engagement on the cross beams and the plurality of flanges defining a plurality of recesses between adjacent flange. The flanges and recesses are adapted for interlocking engagement with corresponding flanges and recesses of an adjacent panel and also include a locking and spacing system for locking adjacent panels together while substantively maintaining a gap between the opposing edges of two adjacent panels.

Abstract: There is provided a new and useful apparatus for applying a removable protective cover to an optical disc in which the optical disc has a circular configuration, an aperture centered therein and an outer edge. The cover comprises at least one sheet of film of generally circular configuration which corresponds to the circular configuration of the disc. The cover is constructed of a material that will not adversely interfere with the read process of the disc when the cover is in place about the disc. The cover further comprises a plurality of resilient clasps spaced about a circumferential edge of the film to engage the disc about its outer edge in a snap-on spring-like fit.

Abstract: A surface covering tile is disclosed having integral connecting elements about its edges to enable hinged interconnection between adjacent-like tiles. The connecting elements are longitudinally arranged about the peripheral edges of the tile and comprise semi-cylindrical curved female elements, protruding tongue elements and semi-cylindrical bar-like male elements. The elements are arranged such that the female and tongue elements cooperate to engage with the male elements of adjacent tiles. The tile is further adapted to receive a surface covering such as a carpet or mat, preferably an air permeable covering which will permit air to pass through apertures in the surface of the tile to the ground below.

Abstract: A multi-tiered system of leveller units for the levelling of recreational vehicles. The leveller units each comprise a planar body, with upper and lower surfaces circumscribed by edges. The body of each unit bears a plurality of pins upwardly extending from spaced locations in the upper surface and has a plurality of pin-engaging pockets formed in the lower surface to matably receive corresponding pins of other similar units. The pins are of slightly smaller size than the corresponding pockets so that when the pins of one unit are associated with the pockets of another, there is provided a loose engagement therebetween. The body may be formed of a discontinuous webbing providing light-weight strength and support to the units to support the large loads placed thereupon.
