Conductive materials
First Claim
1. A flexible semi-conductive material in sheet form characterized by spaced first rails for the supply and return of electrical power, the said rails having a flexibility compatible with the semi-conductive material, and there being a supplementary rail attached to each first rail along the length thereof, the supplementary rails being flexible and having strength characteristics greater than those of the first rails, characterised in that the supplementary rails are a braid formed from conductive wires, the wire diameters being of a size that affords considerable individual flexibility, but relatively low strength, but which when interwoven with other wires, forms a braid that has a flexibility that is commensurate with the flexibility of the sheet of semiconductive material and the first rails.

Abstract
The invention relates to conductive materials particularly to serve as a heater. Heating means formed by or with electrically conductive materials are known and particularly effective for its flexibility is that sold under the British, Community and US Registered Trade Mark INDITHERM. Conductive rails are used to provide electrical connection to a source of power that need to have a commensurate flexibility, and the object of the invention is to ensure the maintenance of power to the full length of the conductive rail. This objective, is met by a construction comprising spaced first rails for the supply and return of electrical power, the said rails having a flexibility compatible with the semi-conductive material, and there being a supplementary rail attached to each first rail along the length thereof, the supplementary rails being flexible and having strength characteristics greater than those of the first rails.
