Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
113 words
Apparatus for connecting light transmitting fiber optic elements comprising: a clear adhesive sensitive to ultraviolet light for positioning between the ends of said elements to be connected; a source of ultraviolet light capable of curing said adhesive; and means for distributing said light substantially around the perimeter of said ends with said adhesive thereon to cure all areas of the adhesive simultaneously to provide a uniformly stressed fiber optic connection; said means comprising a plurality of fiber optic conductors having their ends circumferentially disposed around the ends of the fiber optic elements to be connected, the opposite ends of said conductors being bundled and disposed in the light path from said light source.
Claim 2
Dependent Claim
113 words
Apparatus for connecting light transmitting fiber optic elements comprising: a clear adhesive sensitive to ultraviolet light for positioning between the ends of said elements to be connected; a source of ultraviolet light capable of curing said adhesive; and means for distributing said light substantially around the perimeter of said ends with said adhesive thereon to cure all areas of the adhesive simultaneously to provide a uniformly stressed fiber optic connection; said means comprising a plurality of fiber optic conductors having their ends circumferentially disposed around the ends of the fiber optic elements to be connected, the opposite ends of said conductors being bundled and disposed in the light path from said light source.
Claim 3
Dependent Claim
116 words
Apparatus for adhesively connecting together the end of optical fibers comprising: a body having an axial bore opening to receive said fibers in longitudinally aligned relationship; said body having a plurality of openings circumferentially disposed around said body and extending radially inwardly leading to said axial bore opening; a plurality of fiber optic conductors, each having an input end and an output end secured within a respective radial opening; a source of ultraviolet light; means for introducing the ultraviolet light at the input ends of the fiber optic conductors so that the light is radiated into the body opening in a manner to surround the entire connection to cure the adhesive positioned between the fiber ends.
Claim 4
Dependent Claim
116 words
Apparatus for adhesively connecting together the end of optical fibers comprising: a body having an axial bore opening to receive said fibers in longitudinally aligned relationship; said body having a plurality of openings circumferentially disposed around said body and extending radially inwardly leading to said axial bore opening; a plurality of fiber optic conductors, each having an input end and an output end secured within a respective radial opening; a source of ultraviolet light; means for introducing the ultraviolet light at the input ends of the fiber optic conductors so that the light is radiated into the body opening in a manner to surround the entire connection to cure the adhesive positioned between the fiber ends.
Claim 5
Dependent Claim
27 words
The apparatus of claim 2 wherein said input ends of the conductors are bundled together, and means are provided for focusing the light on the bundled ends.
Claim 6
Dependent Claim
18 words
The apparatus of claim 2 wherein said body is wheel-shaped with the openings oriented in a spoke-like configuration.
Claim 7
Dependent Claim
39 words
The apparatus of claim 4 wherein said body has a radial slot extending from its periphery to the bore opening, the slot being dimensioned to enable the body to be slipped over the adjacent ends of the optical fibers.
Claim 8
Dependent Claim
45 words
The apparatus of claim 5 wherein a housing is provided for enclosing and supporting said body and conductors, said housing having an axial bore opening aligned with the bore opening in the body, and a corresponding radial slot coextensive with the slot in the body.
Claim 9
Dependent Claim
24 words
The apparatus of claim 6 wherein said housing is constructed with a support section, and the entire housing provided with a detachable cover member.
