Abstract: A bulletin board includes a generally planar polyfoam layer having a front surface and a back surface, wherein the back surface includes a recessed surface portion formed therein having an integrally disposed generally planar stiffening member held in place by the polyfoam. The planar stiffening member is preferably a cardboard piece and the polyfoam penetrates a portion of the corrugation from peripheral edges thereof inward. A method of forming the bulletin board is provided.

Abstract: A buffing or polishing device characterized in its preferred embodiment by a hub comprised of a pair of generally dished or cup-shaped segments mounted in base abutted relation and having the base portions thereof adapted to connect to and be fixed for rotation with a drive shaft. The hub segments are identically constructed to include both male and female portions which are interfit and interlocked as the hub segments are placed in base abutted relation. They also include pins which coaxially dispose to provide anchor elements around which strip-like buffing or polishing elements are looped to have their respective ends diverge as they project outwardly from the hub. With the arrangement described, the divergent ends of the strips mutually combine to dispose as circumferentially and relatively widely spaced pairs, the elements of each pair being slightly convergent as they project in a sense radially of and outwardly from the hub.
