Abstract: A polyvinyl chloride powder molding composition is made which is resistant to staining upon thermal exposure when used as a covering for polyurethane articles. Staining of the mold lining is also inhibited. The polymer composition affording these advantages comprises a dry blended mixture of a vinyl chloride resin, a plasticizer, a pigment, a filler and as a thermal stabilizer, a barium-zinc C.sub.6 to C.sub.9 carboxylic acid soap mixture and at least one inorganic magnesium compound.

Abstract: A display device having a plurality of segment light polarizers for receiving incident light thereon and rotatable independently to jointly define sequentially different numerals in dependence upon their relative angular orientation. A common light polarizer is mounted sandwiched between two transparent plates forwardly of the light polarizer for polarizing light from the segment light polarizers and for viewing of the different numerals upon relative angular orientation of the segment light polarizers and relative angular orientation to the common light polarizer. The light polarizers are driven rotationally independently in timed relationship. A mask between the two transparent plates has openings therethrough positioned for viewing the numerals.
