Abstract: A squeegee has a handle consisting of a straight elongate cylindrical member having a pair of elongate blades mounted along one side, flush with one end of the handle and protruding beyond the opposite end. The blades each have a rigid base portion received in one of a pair of channels and a flexible distal portion protruding therefrom for wiping a surface. The blades are integrally formed in a shallow S-shaped cross section and the channels are formed with parallel curved sidewalls conforming to the curvature of a portion of the width of the blade.

Abstract: An adjustable support allows a computer terminal or display device to be conveniently positioned above a desk. The support includes a platform for holding the terminal and a pivotally connected linkage assembly comprising proximal and distal arms for vertically and horizontally positioning the platform, the distal arm having the platform mounted thereon. The proximal arm comprises a set of members forming an articulated parallelogram structure, the proximal end of which is rotatable about a vertical post clamped to the desk. The vertical position of the terminal may be adjusted by changing the shape of the articulated parallelogram structure through operation of a lever coupling members of the articulated parallelogram. As the shape of the parallelogram structure changes, the elevation of the distal end of the proximal arm changes which in turn affects the vertical position of the platform and display device.

Abstract: A platform supporting an electronic device above a work surface, the platform being mounted on a carrier or trolley that is movable between two or more work stations on an elongate base having a track on which the trolley travels. The platform is attached to the trolley by a mounting head that provides tilt and rotation of the platform, and the height of the base above the work surface is adjustable.

Abstract: A passive paper stacker neatly stacks the pages of a sheet of Z-fold paper using only the energy in the falling paper. The first page of the paper is automatically positioned to permit orderly stacking, and diving folds are arrested and redirected toward their proper place on the paper stack.
