Abstract: A utility trailer with a movable bed floor includes a trailer frame supported by a plurality of wheel assemblies. A bed panel is coupled with the trailer frame and defines an upper support surface. A live-bed flexible member spans the length and width of the upper support surface. A load chain is coupled between forward and rearward ends of the live-bed flexible member and span the length of the bed panel below the bed panel. A drive system is supported by the trailer frame. The drive system has a sprocket engaged with the load chain and is operable to drive the live-bed flexible member in forward and rearward directions over the upper support surface for loading and unloading items from the utility trailer.

Abstract: In some cases a composite cutting blade includes one or more cutting segments along a periphery of a hub segment. According to an example, the hub segment and the one or more cutting segments can comprise the same or different porous material. A metallurgical bond between the one or more cutting segments and the hub segment is created by a metal which infiltrates the porous material of both segments. The one or more cutting segments also include a cutting material which at least partially defines a cutting edge and/or a cutting surface of each cutting segment extending along the periphery of the composite blade.

Abstract: A concrete finishing apparatus and method for smoothing and flattening partially cured concrete to a close-tolerance surface includes a movable unit which is movable and entirely supported on or over a partially cured concrete surface and at least one rotatable finishing member, such as a cylindrical tube, roller or the like, mounted to the movable unit. The rotatable finishing member is positioned at the partially cured concrete surface and rotatable to engage and finish the surface of the partially cured concrete to a high quality, close-tolerance flat and level concrete floor surface. The rotatable finishing member is preferably rotatable in a direction generally opposite to the direction of travel of the movable unit to enhance the finishing process and to carry any cement paste or residue forward with the finishing member to fill in any low areas as the concrete finishing apparatus moves over the partially cured concrete.
