Patent number: 7496255Abstract: A glass article comprising a glass substrate and a diamond-like film deposited on the substrate is disclosed. The glass article is desirably responsive to actinic radiation, such as being capable of demonstrating a change in refractive index upon exposure to actinic radiation. The film permits passage of the actinic radiation through the film and into the substrate. In specific implementations, the film comprises at least about 30 atomic percent carbon, from about 0 to about 50 atomic percent silicon, and from about 0 to about 50 atomic percent oxygen on a hydrogen-free basis.Type: GrantFiled: June 22, 2004Date of Patent: February 24, 2009Assignee: 3M Innovative Properties CompanyInventors: Bryon James Cronk, Trevor Wayne MacDougall, Moses Mekala David, Brian John Gates, James Francis Brennan, III

Patent number: 6783597Abstract: A filament coating apparatus comprising a frame for releasably securing a filament, and a carriage mounted on the frame to oscillate between a first position and a second position. There is a first filament holding fixture mounted on the carriage and a second filament holding fixture also mounted on the carriage in axial alignment with the first filament holding fixture to secure a measured filament portion, preferably of an optical fiber, including a bare portion thereof, located inside a first boundary and a second boundary, between the first filament holding fixture and the second filament holding fixture. At least one spray head is attached to the frame at the first position with at least one radiation source attached to the frame at the second position.Type: GrantFiled: March 13, 2001Date of Patent: August 31, 2004Assignee: 3M Innovative Properties CompanyInventors: Bryon James Cronk, David L. Kordecki, Christopher B. Walker, Jr., Brian John Gates

Patent number: 6696157Abstract: A diamond-like glass film is disclosed. In specific implementations, the film includes a diamond-like glass containing at least about 30 atomic percent carbon, at least about 25 atomic percent silicon, and less than or equal to about 45 atomic percent oxygen on a hydrogen-free basis. The diamond-like glass film may be applied to various substrates. The invention is also directed to articles having a diamond-like glass film, methods of making the articles, and apparatus for making the film and to articles.Type: GrantFiled: March 5, 2000Date of Patent: February 24, 2004Assignee: 3M Innovative Properties CompanyInventors: Moses Mekala David, Brian John Gates, Brian Kenneth Nelson, Louis C. Haddad, Joel Rivard Dufresne

Patent number: 6532327Abstract: A method for manufacturing an optical fiber refractive index grating. The method comprises the steps of, providing a substantially twist-free length of an optical fiber between a first spool and a second spool before attaching the first spool and the second spool to a support having a first surface opposite a second surface. The support and spools provide a filament organizer including the first spool as a lockable spool and the second spool as a rotary spool. The filament organizer further comprises a tensioner coupled to the rotary spool to apply tension to at least a central portion of the length of an optical fiber disposed between the lockable spool and the rotary spool.Type: GrantFiled: March 13, 2001Date of Patent: March 11, 2003Assignee: 3M Innovative Properties CompanyInventors: Anthony William Gatica, Bryon James Cronk, William Vogel Dower, John Thomas Cowher, Stephen Paul LeBlanc, Dwayne L. LaBrake, Brian Kenneth Nelson, Christopher B. Walker, Jr., Ronald Phillip Pepin, Brian John Gates
