US Patent:

41296281, Dec 12, 1978
Filed:

Jul 19, 1976
Appl. No.:

5/706449
Inventors:

Donald J. Tamutus - Trenton NJ
Assignee:

RCA Corporation - New York NY
International Classification:

B29D 1100
US Classification:

264 1
Abstract:

A method of making an array of lenses includes the steps of softening a sheet of optically transparent thermoplastic material, such as a clear acrylic resin and vacuum forming the softened sheet into an array of lens shells. The shells are then filled with a clear cast acrylic-polyester resin having an index of refraction closely matching that of the sheet. A thin film of polyester material is placed over the plane surface of the cast resin and a sheet of glass is placed over the film. The resin is cured in an oxygen-inhibited atmosphere at room temperature and the glass and film are then removed, forming a planar surface on one side of each of the lenses, the other surface being convex and being formed by the acrylic resin sheet.

US Patent:

43415911, Jul 27, 1982
Filed:

Apr 8, 1981
Appl. No.:

6/252250
Inventors:

Donald J. Tamutus - Mercerville NJ
Assignee:

RCA Corporation - New York NY
International Classification:

B44C 122
C03C 1500
C03C 2506
C23F 102
US Classification:

156630
Abstract:

Method comprises providing a blank laminate consisting essentially of a positive-acting photosolubilizable central layer, first and second etchable metal layers adhered to opposite sides of the central layer and first and second etch-resistant stencils contacting the outer major surfaces of the first and second metal layers. The stencils have different, related open areas therethrough which leave selected portions of the metal layers unprotected. The unprotected portions of the first and second metal layers are etched through, thereby producing first and second openings in the metal layers. Then the central layer is exposed to actinic light through the first and/or second openings, thereby solubilizing selected portions of the central layer, which solubilized portions are then removed.

US Patent:

46504354, Mar 17, 1987
Filed:

Dec 18, 1980
Appl. No.:

6/217797
Inventors:

Donald J. Tamutus - Mercerville NJ
Assignee:

RCA Corporation - Princeton NJ
International Classification:

H01J 900
US Classification:

445 47
Abstract:

The novel method comprises (a) producing on one surface of a metal plate an array of substantially-parallel ridges, at least the tops of the ridges being electrically insulating, (b) producing an array of generally rectangular-shaped apertures through the plate in columns between the ridges and (c) producing electrically-conducting strips on the tops of the ridges.
