Abstract: A sheet cover for a bicycle wheel is provided consisting of two "half-moon" or approximately semi-circular sheets coated on one side with removable adhesive. The sheet material is stretched to reach beyond the rim of the bicycle wheel and adhered to the lateral surface of the rim by pressing the sheet against the rim. The wheel cover or sheet actually consists of two pieces which extend slightly beyond the center line so that they overlap. To avoid interference with the continued action of the brake shoes which are designed to press against the rim of the wheel for braking action, a box-like protector piece of drawn aluminum or other suitable material is fitted over the brake shoe which, being composed of a rubber-like material, would otherwise tend to tear the wheel cover. The half-moon pieces may be of different colors for decorative effect and may carry a printed advertising or identifying message.

Abstract: A building system is disclosed for constructing non-load-bearing walls in a building having preexisting ceiling and floor structures, using substantially dimensionally identical, lightweight wall panels. The wall panels are rectangular and each has a pair of facing sheets adhesively bonded to a plurality of elongate spacers. The facing sheets of each wall panel overlie each other and have aligned side and end surfaces which define sides and ends of the wall panel. Outer ones of the spacers are inset from the sides of their wall panel, whereby the back surfaces of the facing sheets and the outer spacers cooperate to define channels along the sides of the panels. Preformed elongate ceiling and floor runners are secured to the ceiling and floor structures, and the wall panels are positioned, one at a time, in mating engagement with the floor and ceiling runners to form continuous walls.
