    Abstract: An oval or elliptical shaped overhead conductor that is twisted along its length to provide a continuously varying profile to the wind. A single core is comprised of a circular center wire wrapped by circular wires and the core is surrounded or encased by one or more layers of wire strands, including strands of different size from that of the core wires. Each layer is helically wound in a direction opposite to the underlying layers. The surrounding strands may be circular, with the strand sizes symmetrically arranged to result in a substantially oval or elliptical cross-section. Alternatively, the strands may be shaped into symmetrically arranged non-circular arcuate cross-sections, which when wound together result in an oval or elliptical conductor cross-section. The core strands are each circular or round wires having the same diameter, with the result that the core is easy and inexpensive to manufacture. The conductor is capable of manufacture in one step by winding the core and outer layers at the same time. A helical winding along the length of the conductor results in altering the profile that is presented to the wind, thereby substantially cancelling wind-induced forces in adjacent conductor segments or regions, thus damping conductor vibrations.

    Abstract: A steel cord is disclosed for use in reinforcing rubber products, especially automobile tires. In order to provide desirable rubber penetrability and break-resistance, three to six material wires are intertwisted into a steel cord having an elliptically shaped cross section having a ratio of its major diameter to its minor diameter of between 1.1 and 2.2. The cord is formed such that its material wires substantially contact each other near the ends of the major axis of the ellipse and are separated from each other near the end of the minor axis. The cord of the invention is normally formed such that a ratio the twist pitch to the material wire diameter is in the range of 30-80. However, if a high elongation of more than 5% is necessary, such can be imparted by intertwisting material wires such that the ratio of the twist pitch to the material wire diameter is in the range of 10-28.

    Abstract: A method of manufacturing twisted wire products having a core and at least one outer layer of wires laid about the core consists in arranging the outer layer of wires in two groups during manufacture; one group, which is a substantial fraction of the number of wires in the outer layer is twisted and disposed in contact with the core so as to form as many peripheral gaps as there are remaining wires other than those in the fraction; the second group of wires which are the remaining wires are disposed in periphearl gaps so formed, and laid radially away from the core and in contact with adjacent wires of the first group; the outer layer so arranged in two groups is subjected to radially compressive deforming forces so as to wedge the conductors of the second group into the peripheral gaps so as to produce a tight and improved twisted wire product. Circular wires of the same diameter may be used for the core and the outer layer. Twisted wire products having a plurality of outer layers may be produced by forming single outer layers as said and building them in succession; alternatively, the product may be formed in a single stage of plastic deformation and subsequent thermal treatment as required. The core may be of circular, oval, oblong or triangular shape.
