发明名称 HOSE CONSTRUCTION AND METHOD OF MAKING SAME
摘要 <p>An electric current-carrying fluid hose construction and method of making same are provided herein. Such hose construction is comprised of at least one elongated polymeric strip, preferable formed of an extrudable thermoplastic material, having a central body of solid cross section which has at least one electrical conductor embedded therein. The strip has first and second projections extending from opposite side portions of the central body as a single-piece construction, the projections being disposed in parallel relation and parallel to the central body, each of the projections being defined by a pair of parallel planar surfaces interconnected at their terminal edges by a semi-cylindrical surface. The strip is wound in a helical pattern with its projections connected to define the hose construction with the central body having at least one outwardly convex arcuate surface comprising a pair of semi-cylindrical surfaces having a common longitudinal edge forming the outwardly convoluted configuration and having a substantially flat surface which comprises the substantially smooth inside surface. This structure is relatively inexpensive, provides desirable performance characteristics and does not require expensive manufacturing procedures.</p>
