Abstract: A patient slider device configured to move a patient from a first bed surface to a second bed surface positioned adjacent thereto. The patient slider device includes a frame, a bed engagement assembly and a patient pulling assembly. The bed engagement assembly includes a bumper with the bumper being adjustable relative to the frame. The patient pulling assembly includes a winch assembly, preferably positioned proximate a lower end of the frame, and a sheet engaging clamp assembly. The sheet engaging clamp assembly includes a base member and a locking member structurally configured to clamp a sheet therebetween.

Abstract: A mineral separating gold cube concentrator presents at least two modular portable stacking trays defining alternating inclined surfaces over which a continuing supply of water flows. A first tray provides an inclined smooth surface with controlled water flow to the incline which imparts fluidity allowing the aggregate to move downward and form a slurry that separates the aggregates into lightest first, heaviest last. A second tray is a collection tray is below the first tray and defines a G force separator, forcing all materials under the gate into vertical column within the turbulent water, the column descending upon the vortex mat upon the second tray, forcing the lighter materials within the aggregate to advance ahead of the heavier material. Any material not captured by the vortex mat travels to the end of the matting and is either expelled or subsequently transferred into another collection tray through another G force separator.
