Abstract: There is described an article of manufacture adapted to the display of small commodities such as sunglasses in a convenient and esthetic manner. The commodity display device comprises one or more two-sided columns each of which comprising a box-like outer part comprising twin parts, an S-shaped column insert adapted to be positioned inside said box-like outer part and a column support device adapted to rotatably support said one or more columns in one or more levels and reposition said one or more columns to predetermined positions at rest. In a preferred embodiment, upper and lower vertical shafts extend from the top and bottom portions of each column, each lower vertical shaft has a V-shaped profile at the end portion thereof. In a preferred embodiment a suitable number of columns, for instance six, are arranged on the same level within the supporting device and one or more levels of columns may be provided in the column support device.

Abstract: There is disclosed a method for providing an improved abrasion resistant coating on solid substrates such as plastic articles and solid articles prepared thereby having on the surface such abrasion resistant coating. A solid substrate is coated with an organosilanol-type coating liquid comprising organosilanol molecules, or a precursor thereof or a partial condensation product thereof. At least 90 mole percent of said organosilanol molecules are trifunctional silanol molecules of the formula RSi(OH).sub.3, R being a hydrocarbon radical, and at least 50 mole percent of said trisilanols being an alkyl trisilanols of 1-3 carbon atoms or phenyl trisilanol. Preferably, at least 70 mole percent of the trisilanol is methyltrisilanol. After the coating is cured by a conventional means, it is post-treated by an electron beam irradiation to afford an abrasion resistance far superior to that obtained from organosilanol coating liquids without electron beam irradiation post-treatment.

Abstract: There is described a process for producing, in a continuous manner, a gradient dyeing across the width of a long strip of a plastic sheet and an apparatus used therefor. In a preferred embodiment of the invention, the orientation of the plastic strip is maintained substantially constant during the passage through a dye bath, and the dye liquid level is repetitively varied by use of a liquid level control means. This invention is particularly useful for making gradient-dyed plastic sheets which in turn are used for making sunglass lenses.

Abstract: There is disclosed a method for providing an improved abrasion resistant coating on solid substrates such as plastic articles and solid articles prepared thereby having on the surface such abrasion resistant coating. A solid substrate is coated with an organosiloxane coating liquid, the coating is cured, and subsequently post-treated by a glow discharge to afford an abrasion resistance far superior to that obtained from organosiloxane coating liquids without glow discharge post-treatment. The organosiloxane coating liquid comprises and organosilonal and/or a partial condensation product thereof.There is also disclosed a mirrored solid substrate such as a plastic having an improved abrasion resistance which has a glow discharge treated organosiloxane coating layer and a mirror layer deposited thereon by a vapor deposition method.

Abstract: Dyeing of plastic articles, particularly sunglass lenses is conducted by use of a dye bath composition comprising a dye and a mixed solvent. At least about 70 weight % of the mixed solvent consists of glycerol and ethylene glycol whose relative ratio is in the range of from 95:5 to 20:80. The dyeing method and the dye bath composition are very advantageous for manufacturing sunglass lenses having high optical and aesthetic quality, particularly for dyeing hard-coated polarized lenses.

Abstract: Removal of haze from plastic articles made of cellulose acetate butyrate, such as light polarizing sunglass lenses made of cellulose acetate butyrate and polyvinyl alcohol, is accomplished by immersing said plastic articles in a substantially water-free bath composition at least 70 weight percent of which comprises an active solvent and a carrier solvent, the former being methyl alcohol, ethyl alcohol, propyl alcohol, butyl alcohol, or any mixture thereof, and the latter being ethylene glycol, glycerol, tricresyl phosphate, butyl phthalate, or any mixture thereof. Preferred values of the relative proportions of the active solvent and the carrier solvent are in the range of 90-5 and 10-95 weight percent, respectively, and more preferably, 80-10 and 20-90 weight percent, respectively.

Abstract: A rimless spectacle including a light weight two member lens supporting nose bridge assembly which engages the brow bar at its upper end and includes a pair of nose engaging pad members extending from its bottom end.
