Abstract: The present disclosure describes a sanding device that has a motor coupled to a base plate for inducing vibration in the base plate. Further, the sanding device has a face plate that is coupled to the base plate, and the face plate has a plurality of sleeves for receiving a respective plurality of columns. The columns rotate and move longitudinally within the sleeves. Further, each column moves independent of the other columns and each column have an abrasive surface on a sanding end for contacting a sanding surface.

Abstract: The invention relates to a patterned device comprising a substrate covered by a pattern of metal and oxidized metal surrounding said pattern of metal.

Abstract: The present invention generally relates to method of forming a polarizing plate comprising providing two cover sheets each comprising a low birefringence protective polymer film and a layer promoting adhesion to poly(vinyl alcohol)-containing films that comprises a dissolved first poly(vinyl alcohol) having a degree of hydrolysis of at least 98%. A glue composition is applied when bringing the PVA dichroic polarizing film into contact with the cover sheets, the glue composition comprising a dissolved second poly(vinyl alcohol) having a degree of hydrolysis of at least 98% in combination with crosslinking agent.
