Abstract
Abstract A method of securing metal fasteners to the surface of a glass object, particularly a spectacle lens, which comprises the steps of applying against said surface, with a predetermined and adjustable pressure, a fastener made of a metal adapted to be easily welded to the glass object and consisting of a piece of extruded section shaped as consistent with the manner in which the fastener is to be accomadating subsequently, the glassengaging base of said fastener accompdating the contour of said glass surface, and the step of vibrating each fastener at a supersonic frequency during a few seconds.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
134 words
A method of securing metal fasteners to the surface of a glass spectacle lens, which comprises the step of applying against said surface, with a predetermined and adjustable pressure, at least one fastener made of a metal adapted to be easily welded to the glass material of the lens and consisting of a piece of extruded section shaped as consistent with the manner in which the fastener is to be used subsequently, each fastener having a glass-engaging base accommodating the contour of said glass lens surface, and being applied against said surface of the lens in a predetermined orientation also consistent with the manner in which the fastener is to be used subsequently, and the step of vibrating each fastener at a supersonic frequency during a few seconds while maintaining constant said predetermined orientation.
Claim 2
Independent Claim
134 words
A method of securing metal fasteners to the surface of a glass spectacle lens, which comprises the step of applying against said surface, with a predetermined and adjustable pressure, at least one fastener made of a metal adapted to be easily welded to the glass material of the lens and consisting of a piece of extruded section shaped as consistent with the manner in which the fastener is to be used subsequently, each fastener having a glass-engaging base accommodating the contour of said glass lens surface, and being applied against said surface of the lens in a predetermined orientation also consistent with the manner in which the fastener is to be used subsequently, and the step of vibrating each fastener at a supersonic frequency during a few seconds while maintaining constant said predetermined orientation.
Claim 3
Dependent Claim
28 words
The method as set forth in claim 1, wherein, upon a plurality of fasteners being secured to a same glass surface, said fasteners are vibrated separately and successively.
Claim 4
Dependent Claim
26 words
The method as set forth in claim 1, wherein said at least one fastener is vibrated at a supersonic frequency of the order of 40,000 Hz.
Claim 5
Independent Claim
111 words
A method of securing metal fasteners to the surface of a glass object, particularly a spectacle lens, which comprises applying against said surface, with a predetermined and adjustable pressure, at least one fastener made of a metal adapted to be easily welded to the glass object and consisting of a relatively short piece of T-section having a small hole formed through the central web of the T- to permit a subsequent insertion of a retaining screw therethrough, the glass-engaging base of the fastener accommodating the contour of said glass surface, and vibrating said at least one fastener at a supersonic frequency during a few seconds while maintaining constant said predetermined orientation.
Claim 6
Independent Claim
111 words
A method of securing metal fasteners to the surface of a glass object, particularly a spectacle lens, which comprises applying against said surface, with a predetermined and adjustable pressure, at least one fastener made of a metal adapted to be easily welded to the glass object and consisting of a relatively short piece of T-section having a small hole formed through the central web of the T- to permit a subsequent insertion of a retaining screw therethrough, the glass-engaging base of the fastener accommodating the contour of said glass surface, and vibrating said at least one fastener at a supersonic frequency during a few seconds while maintaining constant said predetermined orientation.
Claim 7
Independent Claim
101 words
A method of securing metal fasteners to the surface of a glass object, particularly a spectacle lens, which comprises applying against said surface, with a predetermined and adjustable pressure, at least one fastener of a material adapted to be easily welded to the glass object and consisting of a section of cylindrical wire to permit a subsequent snap-fitting of the glass and fastener assembly in a mounting, the glass-engaging base of the fastener accommodating the contour of said glass surface, and vibrating said at least one fastener at a supersonic frequency during a few seconds while maintaining constant said predetermined orientation.
