Abstract
Abstract An end portion of an elongate member of generally cylindrical form, such as an optical fiber, is placed in a predetermined position utilizing a substrate having a surface that is defined by a generatrix that is a straight line, e.g. a flat surface. A foil of flexible material is secured to the surface of the substrate and defines with the substrate a generally straight, elongate passageway that is parallel to the generatrix of the surface and has a first portion of substantially uniform cross-section adapted to receive an end of the elongate member in closely fitting relationship and also has a second portion that tapers towards the first portion. The end portion of the elongate member is inserted into the first portion of the passageway by way of the second portion thereof.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
84 words
An article of manufacture comprising a substrate having a surface that is defined by a generatrix that is a straight line, and a foil of flexible material that defines with the substrate a generally straight, elongate passageway that is parallel to the generatrix of said surface and has a first portion of substantially uniform cross-section adapted to receive an end of an elongate member of generally cylindrical form in closely fitting relationship and also has a second portion that tapers towards said first portion.
Claim 2
Dependent Claim
84 words
An article of manufacture comprising a substrate having a surface that is defined by a generatrix that is a straight line, and a foil of flexible material that defines with the substrate a generally straight, elongate passageway that is parallel to the generatrix of said surface and has a first portion of substantially uniform cross-section adapted to receive an end of an elongate member of generally cylindrical form in closely fitting relationship and also has a second portion that tapers towards said first portion.
Claim 3
Dependent Claim
60 words
An article according to claim 1, wherein the passageway is bounded by a strip-form portion of said surface, and the foil has marginal regions extending along opposite edges thereof and said marginal regions are secured to the substrate in a manner such that the marginal regions lie in a plane that is spaced from said strip-form portion of said surface.
Claim 4
Dependent Claim
42 words
An article according to claim 2, wherein said surface is flat and wherein said article comprises first and second spacers secured to said surface at opposite sides thereof respectively, and the marginal regions of the foil are secured to said spacers respectively.
Claim 5
Dependent Claim
24 words
An article according to claim 2, wherein said surface is concavely curved and the margins of the foil are secured directly to the substrate.
Claim 6
Dependent Claim
92 words
In combination, an article of manufacture comprising a substrate having a surface that is defined by a generatrix that is a straight line, a foil of flexible material that defines with the substrate a generally straight, elongate passageway that is parallel to the generatrix of said surface and has a first portion of substantially uniform cross-section and also has a second portion that tapers towards the first portion, and an elongate member of generally cylindrical form having an end portion that extends within said first and second portions of the elongate passageway.
Claim 7
Dependent Claim
92 words
In combination, an article of manufacture comprising a substrate having a surface that is defined by a generatrix that is a straight line, a foil of flexible material that defines with the substrate a generally straight, elongate passageway that is parallel to the generatrix of said surface and has a first portion of substantially uniform cross-section and also has a second portion that tapers towards the first portion, and an elongate member of generally cylindrical form having an end portion that extends within said first and second portions of the elongate passageway.
Claim 8
Dependent Claim
83 words
A combination according to claim 5, wherein said passageway has a third portion at the opposite end of the first portion from said second portion, said third portion tapering towards said first portion, and further comprising a second elongate member of generally cylindrical form and of diameter substantially equal to that of the first-mentioned member having an end portion that extends within the first and third portions of the passageway and is in end-to-end alignment with the end portion of the first-mentioned member.
Claim 9
Dependent Claim
51 words
A combination according to claim 6, wherein said first-mentioned member and said second member comprise first and second sections respectively of optical fiber and the combination also comprises index-matching material in said first portion of the passageway between the confronting end surfaces of the first and second sections of optical fiber.
Claim 10
Dependent Claim
15 words
A combination according to claim 7, wherein said index-matching material is a cured adhesive material.
Claim 11
Dependent Claim
113 words
An article of manufacture fabricated by providing a substrate having a surface that is defined by a generatrix that is a straight line, securing to said surface a foil of flexible material that defines with the substrate a generally straight, elongate passageway that is parallel to the generatrix of said surface and has a first portion of substantially uniform cross-section adapted to receive an end portion of an elongate member of generally cylindrical form in closely fitting relationship and also has a second portion that tapers towards said first portion, and inserting said end portion of the elongate member into the first portion of the passageway by way of said second portion thereof.
Claim 12
Dependent Claim
113 words
An article of manufacture fabricated by providing a substrate having a surface that is defined by a generatrix that is a straight line, securing to said surface a foil of flexible material that defines with the substrate a generally straight, elongate passageway that is parallel to the generatrix of said surface and has a first portion of substantially uniform cross-section adapted to receive an end portion of an elongate member of generally cylindrical form in closely fitting relationship and also has a second portion that tapers towards said first portion, and inserting said end portion of the elongate member into the first portion of the passageway by way of said second portion thereof.
Claim 13
Dependent Claim
105 words
An article according to claim 9, wherein said passageway has a third portion at the opposite end of the first portion from said second portion, said third portion tapering towards said first portion, and wherein the article is manufactured by a method that further comprises inserting an end portion of a second elongate member of generally cylindrical form and of diameter substantially equal to that of the first-mentioned member into the first portion of the passageway by way of said third portion thereof so as to place the end portion of the second member in end-to-end alignment with the end portion of the first-mentioned member.
Claim 14
Dependent Claim
51 words
An article according to claim 10, wherein said first-mentioned member and said second member comrpise first and second sections respectively of optical fiber and the article also comprises index-matching material in said first portion of the passageway between the confronting end surfaces of the first and second sections of optical fiber.
