US Patent:41209923, Oct 17, 1978
-
Filed:Jun 23, 1977
-
Appl. No.:5/809497
-
Inventors:Bernard L. Laurin - Ludlow MA
Don H. Rotenberg - Westboro MA
Harry D. Crandon - Woodstock CT -
Assignee:American Optical Corporation - Southbridge MA
-
International Classification:B05D 302
B05D 306
B05D 310
G02B 110 -
US Classification:427164
-
Abstract:An abrasion-resistant organic optical element comprising a transparent base of a synthetic organic material having an adhering coating of an abrasion-resistant material comprising a polysilicic acid ester of an alcohol containing from 1 to 12 carbon atoms and a partially hydrolyzed vinyl polymer to provide polyvinyl alcohol, the coating being cross-linked with formaldehyde or zirconyl nitrate or mixtures thereof. The abrasion-resistant organic optical elements can comprise sheet material or a lens.

US Patent:51578808, Oct 27, 1992
-
Filed:Jun 28, 1991
-
Appl. No.:7/724503
-
Inventors:Don H. Rotenberg - Tulsa OK
Milton F. Whitmarsh - Tulsa OK -
Assignee:Coburn Optical Industries - Muskogee OK
-
International Classification:B24D 1700
-
US Classification:51358
-
Abstract:A lap used for the grinding, fining and polishing of glass and plastic lenses is constructed of a one-piece injection-molded reinforced polymer body. The front surface of the lap is curved and adapted to receive an abrasive pad. The rear of the lap has a skeletal rib structure of projecting interconnected ribs. Polymers suitable for forming the lap include various crystalline polymers and copolymers having adequate chemical resistance, strength, rigidity and thermal resistance.

US Patent:41734904, Nov 6, 1979
-
Filed:Apr 18, 1978
-
Appl. No.:5/897317
-
Inventors:Don H. Rotenberg - Westboro MA
Patricia M. Cuffe - Dudley MA
Bernard L. Laurin - Ludlow MA
Peter R. Ramirez - Southbridge MA -
Assignee:American Optical Corporation - Southbridge MA
-
International Classification:C09K 300
-
US Classification:10628714
-
Abstract:A coating composition which results from hydrolyzing 40 to 70 weight per cent tetraethyl orthosilicate and 60 to 20 weight per cent of certain silane is useful for providing abrasion resisting coatings for plastics after curing. Optionally, up to 20 weight percent of a silane having a reactive polar site or, in the alternative, a small percentage of a surfactant may be used to provide a dyeable coated article.

Assignee:American Optical Corporation - Southbridge MA
-
International Classification:B05D 306
-
US Classification:427 40
-
Abstract:Novel anti-static and/or anti-reflective optical elements are produced by coating at least one surface of an organic polymeric plastic substrate with a protective organo-silica coating composition and then subjecting the coated plastic substrate to a glow discharge treatment.
