Abstract
A multi-member cable includes at least a first cable element and a second cable element. The first and second cable elements may extend in parallel, be stranded in a helical winding pattern, or be stranded in a reverse-oscillatory winding pattern, along the length of the cable. At least one binder is helically wrapped about the first and second cable elements to hold them together. The binder is formed of a material which disintegrates when exposed to a particular liquid or heat. In a preferred embodiment, the binder may be formed of polyvinyl-alcohol (PVA).
Claims19
A multi-member cable comprising:
- a first cable element;
- a second cable element, wherein said first and second cable elements abut each other to form a cable core;
- at least one binder helically wrapped about and surrounding said cable core, so as to hold said first and second cable elements together within said cable core during a cable manufacturing process, wherein said at least one binder is formed of a first material which disintegrates to permanently lose tensile strength when either bought into contact with a liquid or when heated, or both;
- and
- an outer jacket formed over said first and second cable elements and said at least one binder, wherein said first material disintegrates to permanently lose at least 25% of its tensile strength within less than one minute when bought into contact with a liquid having a ph of between 4 and 10.

- and
- an outer jacket formed over said first and second cable elements and said at least one binder, wherein said first material disintegrates to permanently lose at least 25% of its tensile strength within less than one minute when heated to a temperature greater than 200 degrees Fahrenheit, but less than 600 degrees Fahrenheit.
