Abstract: A banding bead which is attachable to a base structure for providing a guide and form for retaining plaster or other plastic materials thereagainst at two different heights. The banding bead includes a base portion and a generally planar elongated support segment extending generally perpendicularly away said base portion. The banding bead is extruded from a selected material or formed from a strip of sheet material. The support segment has a first planar side, a second planar side, and a top screed portion distal the base portion. A screed lip is disposed on the second planar side between the top screed portion and the base portion. The base portion includes primary and secondary feet extending from the support segment for attachment to the underlying base structure and to provide stability.

Abstract: An optical device, adapted to give varying "depth of field" effects. The device hereof utilizes first and second reflective surfaces, at least one of which is movable with respect to the other. A light source is interposed between the two reflective surfaces.
