Abstract: An integrally formed fibreglass fin assembly (1) including a base (2)—that is defined by broken lines (3,4)—for mounting the assembly to an object in the form of a surfboard (5). A primary fin (6) extends upwardly from base (2)—in that it extends upwardly from line (3)—and has a compound arcuate leading primary edge (7) and a compound arcuate trailing primary edge (8). A secondary fin (9) extends rearwardly and upwardly from base (2)—in that it extends from line (4)—and has a compound arcuate leading secondary edge (10) and a compound arcuate trailing secondary edge (11).

Abstract: A wringer has a support surface and a first wringer surface depending from the support surface to a second wringer surface having perforations and curving to a free edge substantially below the support surface. The second wringer surface may be curved in an approximately 180 degree arc. The first wringer surface may be flat and also perforated. The support surface may be formed as an inverted channel structure with a closed upper surface and an angled surface extending away from the first wringer surface. The angled surface may extend at an angle approximately 45 degrees. The wringer may be used with one or more buckets, where the wringer is supported from the rim of one bucket or from the adjacent rims of two buckets. A flat first wringer surface may be used to ring a flat mop, and the curved second wringer surface may be used to bring a round mop.

Abstract: Abrading and cutting devices such as saws include waste containment systems and methods to improve removal of slurry or other contaminants from a work area during operations, and separation of slurry from a carrying medium such as air. A blade guard includes fluid channels, and may be removable from a blade guard carriage. The carriage may be used to minimize any need to readjust the blade guard position when the blade guard is returned to the carriage for further use. A vacuum bar may be included on the carriage. A vacuum pickup assembly may be used with a blade guard, and the vacuum assembly may include separate and/or different vacuum pickup configurations.

Abstract: A drill assembly, for example for drilling or coring concrete, has a drill column formed from a composite material. A track for a wall saw or for supporting other structures for movement along the track is formed from a composite material. A composite column, rail or other longitudinally extending composite structure having a hollow interior portion includes an internal support structure.

Abstract: The present invention relates to a variable floor (1) for a body of water, the variable floor (1) including a base portion (2) for location on or within a fixed floor (106) of the body of water and means to adjust the slope of the upper surface of the variable floor (1) relative to the fixed floor (106) or base portion (2) in one or both of a first direction transverse to the direction of travel of waves and in a second direction transverse to the first direction. A wavepool (100) incorporating the variable floor (1) and including variable converging side walls, a kit of parts for the variable floor (1) and a method of controlling wave characteristics is also described.

Abstract: Perimeter frame rails and door frames rails are described for a more thermally efficient and cost-effective display case such as for refrigerated display cases. The frames are preferably formed from cold rolled steel. A perimeter frame may include first, second and third walls defining an opening or a recess that can be closed by a contact plate. A door for a refrigerated display case may include a glass unit and a forward portion extending inwardly from a perimeter frame edge portion toward an edge of the forward glass pane and a first side portion extends rearwardly to a groove. An insulating member insulates the door rail from the cold area and includes a portion engaging the groove. A glass door is also provided for a refrigerated display case having a first glass panel, a second glass panel, and low emissivity coatings on the inside surfaces of the first and second glass panels. One or more intermediate glass panels can also be included.

Abstract: A door closure mechanism is described including a base and a resilient element wherein the base includes surfaces which converge toward each other and wherein the resilient element, such as a torque rod, engages the converging surfaces so that the torque rod is more securely held in the base.

Abstract: A display case lighting system having a lens positioned inside a display came adjacent a light source inside the case for directing light across a viewing plane within the case and reducing contrasting illumination of items displayed within the viewing plane.

Abstract: A refrigerator door for a refrigerated display case includes a glass unit having first and second spaced apart glass panels where the first panel has a forward facing surface and the second panel has a rearward facing surface. A spacer element extends between the first and second glass panels. A door rail element includes an external perimeter wall extending from a point adjacent the edge of the first glass panel to a point adjacent the second glass panel. The door rail element also includes a portion which extends within the space between the first and second spaced apart glass panels and a portion which extends externally of the spaced apart glass panels to the perimeter wall. The door rail element further includes a rear wall portion extending inwardly toward the center of the door from the perimeter wall and over a portion of the rearward facing surface of the second glass panel. In one aspect, one or more of the door rail elements may be formed from a composite, for example, resin and glass fibers.

Abstract: A shelving system, shelf support and shelf are provided that are adjustable vertically, horizontally and angularly for better product presentation and maintenance. Brackets are provided which allow depth or horizontal adjustment and another bracket is provided which gives shelf support and allows easier horizontal adjustment. The brackets also permit easier and more reliable vertical and shelf angle adjustments for better product presentation. Shelf assemblies are provided which include adjustable product stops and dividers. Other shelf and product presentation features are also provided.
