Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 133 words
A method for the production of a light conductor having opposite ends and composed of a plurality of thin fibers, wherein at least one of said ends is divided into a plurality of strands and wherein each strand of said one end comprises fibers of a specific one of a plurality of regions at the other end arranged in any desired pattern, said method comprising the steps of producing at said other end an illuminated pattern of any desired outline so that some of the fibers will be light carrying fibers and the other non-light carrying fibers; displacing said light carrying fibers and said non-light carrying fibers with respect to each other by a photoelectric control rod punch; and connecting said light carrying fibers, respectively said non-light carrying fibers into said separate strands.
Claim 2
Independent Claim 133 words
A method for the production of a light conductor having opposite ends and composed of a plurality of thin fibers, wherein at least one of said ends is divided into a plurality of strands and wherein each strand of said one end comprises fibers of a specific one of a plurality of regions at the other end arranged in any desired pattern, said method comprising the steps of producing at said other end an illuminated pattern of any desired outline so that some of the fibers will be light carrying fibers and the other non-light carrying fibers; displacing said light carrying fibers and said non-light carrying fibers with respect to each other by a photoelectric control rod punch; and connecting said light carrying fibers, respectively said non-light carrying fibers into said separate strands.
Claim 3
Independent Claim 130 words
A method for the production of a light conductor having opposite ends and composed of a plurality of thin fibers, wherein at least one of said ends is divided in a plurality of strands, and wherein each strand of said one end comprises fibers of a specific one of a plurality of regions at the other end arranged in any desired pattern, said method comprising the steps of producing at said other end in illuminated pattern of any desired outline so that some of said fibers will be light carrying fibers and the other non-light carrying fibers; displacing said light carrying fibers and said non-light carrying fibers with respect to each other by gas impulses; and connecting said light carrying fibers, respectively said non-light carrying fibers into said separate strands.
Claim 4
Independent Claim 130 words
A method for the production of a light conductor having opposite ends and composed of a plurality of thin fibers, wherein at least one of said ends is divided in a plurality of strands, and wherein each strand of said one end comprises fibers of a specific one of a plurality of regions at the other end arranged in any desired pattern, said method comprising the steps of producing at said other end in illuminated pattern of any desired outline so that some of said fibers will be light carrying fibers and the other non-light carrying fibers; displacing said light carrying fibers and said non-light carrying fibers with respect to each other by gas impulses; and connecting said light carrying fibers, respectively said non-light carrying fibers into said separate strands.
Claim 5
Independent Claim 160 words
A method for the production of a light conductor having opposite ends and composed of a plurality of thin fibers, wherein at least one of said ends is divided in a plurality of strands and wherein each strand of said one end comprises fibers of a specific one of a plurality of regions at the other end arranged in any desired pattern, said method comprising the steps of producing at said other end an illuminated pattern of any desired outline so that some of said fibers will be light carrying fibers and the other non-light carrying fibers; separating said light carrying fibers from said non-light carrying fibers by securing all fibers at said one end in a row by a light sensitive lacquer to a support, illuminating the lacquer by said light carrying fibers and releasing said light carrying fibers from said support by etching; and connecting said light carrying fibers, respectively said non-light carrying fibers into said separate strands.
Claim 6
Independent Claim 160 words
A method for the production of a light conductor having opposite ends and composed of a plurality of thin fibers, wherein at least one of said ends is divided in a plurality of strands and wherein each strand of said one end comprises fibers of a specific one of a plurality of regions at the other end arranged in any desired pattern, said method comprising the steps of producing at said other end an illuminated pattern of any desired outline so that some of said fibers will be light carrying fibers and the other non-light carrying fibers; separating said light carrying fibers from said non-light carrying fibers by securing all fibers at said one end in a row by a light sensitive lacquer to a support, illuminating the lacquer by said light carrying fibers and releasing said light carrying fibers from said support by etching; and connecting said light carrying fibers, respectively said non-light carrying fibers into said separate strands.
