Filed:

Jul 14, 2000

Appl. No.:

09/616784

Inventors:

Douglas E. Johnson - Minneapolis MN
Tracy L. Anderson - Hudson WI

Assignee:

3M Innovative Properties Company - St. Paul MN

International Classification:

H01B 500

US Classification:

1741261, 1741262, 1741281, 1741282

Abstract:

A stranded cable that includes a plurality of brittle load bearing wires and a means for maintaining the stranded arrangement of the brittle wires. Because the load bearing wires are brittle, they cannot be sufficiently deformed during conventional cable stranding processes in such a way as to maintain their helical arrangement. Therefore, the means for maintaining the helical arrangement of the stranded wires allows the stranded cable to be conveniently provided as an intermediate article or as a final article. When used as an intermediate article, it may be later incorporated into a final article such as overhead power transmission cables. The maintaining means may be a tape, an adhesive tape, or a binder applied to the stranded wires.

International Classification:

H01L 31/042

US Classification:

136246

Abstract:

An article that is suitable for use as a solar concentrating mirror for enhancing the use of solar collection devices, such as solar cells. The article includes a multilayer optical film and a compliant UV protective layer. The article addresses degradation issues in solar concentration devices, provides specific bandwidths of electromagnetic energy to the solar cell while eliminating or reducing undesirable bandwidths of electromagnetic energy that may degrade or adversely affect the solar cell, and renders a compliant sheet of material that may be readily formed into a multitude of shapes or constructions for end use applications.
