Abstract
Abstract 1. A method of forming a glass fiber device including the steps of: forming a fiber bundle comprising a plurality of parallel fibers, heating said fiber bundle to a working temperature, while at the working temperature forcing the ends of said bundle towards each other while contraining the ends of said bundle from radial movement in a plane normal to the longitudinal axis of said bundle to form a fused bundle of glass fibers having generally parallel ends of generally the original cross-section dimension and an outwardly curved bulbous center section immediately adjacent the ends of the bundle.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
97 words
A method of forming a glass fiber device including the steps of: forming a fiber bundle comprising a plurality of parallel fibers, heating said fiber bundle to a working temperature, while at the working temperature forcing the ends of said bundle towards each other while contraining the ends of said bundle from radial movement in a plane normal to the longitudinal axis of said bundle to form a fused bundle of glass fibers having generally parallel ends of generally the original cross-section dimension and an outwardly curved bulbous center section immediately adjacent the ends of the bundle.
Claim 2
Independent Claim
97 words
A method of forming a glass fiber device including the steps of: forming a fiber bundle comprising a plurality of parallel fibers, heating said fiber bundle to a working temperature, while at the working temperature forcing the ends of said bundle towards each other while contraining the ends of said bundle from radial movement in a plane normal to the longitudinal axis of said bundle to form a fused bundle of glass fibers having generally parallel ends of generally the original cross-section dimension and an outwardly curved bulbous center section immediately adjacent the ends of the bundle.
Claim 3
Dependent Claim
18 words
The method of claim 1, wherein the ends of said bundle are forced together along a common axis.
Claim 4
Independent Claim
129 words
A method of forming a glass fiber optic device including the steps of: forming a glass fiber optic bundle comprising a plurality of parallel optic glass fibers, each surrounded by a glass cladding, the index of refraction of said cladding being less than the index of refraction of the said glass fibers, heating said fiber optic bundle to a glass working temperature, while at the working temperature forcing the ends of said bundle towards each other while constraining the ends of said bundle from radial movement in a plane normal to the longitudinal axis of said bundle to form a fused bundle of glass fibers having generally parallel ends of generally the original cross-sectional dimension and an outwardly curved bulbous center section immediately adjacent the ends of the bundle.
Claim 5
Independent Claim
129 words
A method of forming a glass fiber optic device including the steps of: forming a glass fiber optic bundle comprising a plurality of parallel optic glass fibers, each surrounded by a glass cladding, the index of refraction of said cladding being less than the index of refraction of the said glass fibers, heating said fiber optic bundle to a glass working temperature, while at the working temperature forcing the ends of said bundle towards each other while constraining the ends of said bundle from radial movement in a plane normal to the longitudinal axis of said bundle to form a fused bundle of glass fibers having generally parallel ends of generally the original cross-sectional dimension and an outwardly curved bulbous center section immediately adjacent the ends of the bundle.
Claim 6
Dependent Claim
48 words
The method of claim 3 including the further step of surrounding the mid-portion of said fiber optic bundle before the application of force to the ends thereof with a surface of revolution to thereby limit radial outward movement of the fibers in the longitudinal mid-portion of said bundle.
