    摘要： A tire cord which is improved in penetration of rubber into the cord and the fatigue resistance without increasing the diameter of the cord. The tire cord comprises a core and an inner sheath, the core consisting of three steel filaments twisted together, the inner sheath consisting of seven to nine steel filaments twisted around the core in the same direction as the core twist, the twist pitch length of the inner sheath being in the range of from 1.05 to 1.50 times the twist pitch length of the core, the diameter of the core filaments being in the range of from 0.8 to 1.0 times the diameter of the inner sheath filaments.

    摘要： An optical well logging cable and method of fabrication is provided which utilizes the combination of optical fiber means having a proof test stress value of at least about 150,000 pounds per square inch with a surrounding and protecting arrangement of helically wound strength elements in a construction that minimizes the inelastic part of the cable elongation by minimizing the deformability of the structure within the arrangement of strength elements. This arrangement of strength elements includes two torque balancing layers wound in opposite helical directions. It is a feature of this invention that the construction has such a low permanent radial contraction under repeated loading to about 90% of the design breaking strength of the cable that its permanent elongation is no greater than about 0.4% and preferably 0.25% or less.
