Abstract

A method for creating a composite cable having at least one advanced termination on at least one end. An advanced termination is added to an end of a short synthetic tensile strength member. The strength of the tensile strength member and termination is then tested. Once tested satisfactorily, the short cable is spiced onto a long cable of the same type using prior art splicing techniques. The union of the short cable and the long cable creates a “composite” cable having a advanced termination on at least one end. In most applications it is preferable to set the length of the short cable so that the interwoven splice will exist at a desired location.

First claim

1 . A method of creating a composite cable with an advanced termination on one end, wherein the performance of said advanced termination is pre-qualified, comprising:
a. providing a short, cable, having a first end and a second end; b. locking said second end of said short cable into said advanced termination; c. applying a defined test load to said short cable, wherein said defined test load is applied through said advanced termination in order to determine whether said short cable and said advanced termination pass a defined test criterion; d. providing a long cable, having a first end and a second end; and e. after said short cable passes said defined test criterion, joining said first end of said short cable to said second end of said long cable to form said composite cable having a advanced termination on one end.

2 . A method of creating a composite cable as recited in claim 1 , wherein said high-performance termination comprises an anchor that is locked to said second end of said short cable by potting.

3 . A method of creating a composite cable as recited in claim 1 , wherein said high-performance performance termination comprises an anchor that is locked to said second end of said short cable using a spike and cone connection.

4 . A method of creating a composite cable as recited in claim 1 , wherein said joining of said first end of said short cable to said, second end of said long cable is performed by interweaving a section of said short cable into said long cable.

5 . A method of creating a composite cable as recited in claim 2 , wherein said joining of said first end of said short cable to said second end of said long cable is performed by interweaving a section of said short cable into said long cable.

6 . A method of creating a composite cable as recited in claim 3 , wherein said joining of said first end of said short cable to said second end of said long cable is performed by interweaving a section of said short cable into said long cable.

7 . A method of creating a composite cable as recited in claim 1 , further comprising:
a. providing a second short cable, having a first end and a second end; b. providing second advanced termination; c. locking said second end of said second short cable into said second high-performance termination; d. applying a defined test load to said second short cable, wherein said defined test load Is applied through said second advanced termination in order to determine whether said second short cable and said second advanced termination pass a defined test criterion; and e. after said second short cable passes said defined test criterion, joining said first end of said second short cable to said first end of said long cable.

8 . A method of creating a composite cable as recited in claim 2 , further comprising:
a. providing a second short cable, having a first end and a second end; b. providing second advanced termination; c. locking said second end of said second short cable into said second high-performance termination; d. applying a defined test load to said second short cable, wherein said defined test load is applied through said second advanced termination in order to determine whether said second short cable and said second advanced termination pass a defined test criterion; and e. after said second short cable passes said defined test criterion, joining said first end of said second short cable to said first end of said long cable.

9 . A method of creating a composite cable as recited in claim 2 , further comprising:
a. providing a second short cable, having a first end and a second end; b. providing second advanced termination: c. locking said second end of said second short cable into said second high-performance termination; d. applying a defined test load to said second short cable, wherein said defined test load is applied through said, second advanced termination in order to determine whether said second short cable and said second advanced termination pass a defined test criterion; and e. after said second short cable passes said defined test criterion, joining said first end of said second short cable to said first end of said long cable.

10 . A method of creating a composite cable as recited in claim 6 , further comprising:
a. providing a second short cable, having a first end and a second end; b. providing second advanced termination; c. locking said second end of said second short cable into said second high-performance termination; d. applying a defined test load to said second short cable, wherein said defined test load is applied through said second advanced termination in order to determine whether said second short cable and said second advanced termination pass a defined test criterion; and e. after said second short cable passes said defined test criterion, joining said first end of said second short cable to said first end of said long cable.

11 . A method of creating a composite cable with a advanced termination on one end, wherein the performance of said advanced termination is pre-qualified, comprising:
a. providing a short cable, having a first end and a second end; b. creating a advanced termination on said second end of said short cable by attaching an anchor to said second end of said short cable; c. applying a defined test load to said short cable, wherein said defined test load is applied through said anchor in order to determine whether said short cable and said advanced termination pass a defined test criterion; d. providing a long cable, having a first end and a second end: and e. after said short cable passes said defined test criterion, joining said first end of said short cable to said second end of said long cable to form said composite cable having a advanced termination on one end.

12 . A method of creating a composite cable as recited in claim 11 , wherein said high-performance termination comprises an anchor that is locked, to said second end of said short cable by potting.

13 . A method of creating a composite cable as recited in claim 11 , wherein said high-performance termination comprises an anchor that is locked to said second end of said short cable using a spike and cone connection.

14 . A method of creating a composite cable as recited in claim 11 , wherein said joining of said first end of said short cable to said second end of said long cable is performed by interweaving a section of said short cable into said long cable.

15 . A method of creating a composite cable as recited in claim 12 , wherein said, joining of said first end of said short cable to said second end of said long cable is performed by interweaving a section of said short cable into said long cable.

16 . A method of creating a composite cable as recited in claim 13 , wherein said joining of said first end of said short cable to said second end of said long cable is performed by interweaving a section of said short cable into said long cable.

17 . A method of creating a composite cable as recited in claim 11 , further comprising:
a. providing a second short cable, having a first end and a second end; b. providing second advanced termination; c. locking said second end of said second short cable into said second high-performance termination; d. applying a defined test load to said second short cable, wherein said defined lest load is applied through said second advanced termination in order to determine whether said second short cable and said second advanced termination pass a defined test criterion; and e. after said second short cable passes said
