    Abstract: 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.

    Abstract translation: 提供光学测井电缆和制造方法，其利用具有至少约150,000磅/平方英寸的验证测试应力值的光纤装置的组合以及在最小化的结构中的螺旋缠绕强度元件的周围和保护布置 电缆延伸率的非弹性部分通过使结构在强度元件的布置内的可变形性最小化来实现。 这种强度元件的布置包括以相反螺旋方向缠绕的两个扭矩平衡层。 本发明的一个特征是，该结构在反复加载下具有如此低的永久径向收缩，至电缆的设计断裂强度的约90％，其永久伸长率不大于约0.4％，优选为0.25％或更小。

    Abstract: A corrosion resistant rope in which the individual strands are sealed with a plastic foam impregnant and surrounded with a dense unfoamed plastic material is made by applying a foamable plastic to the individual wires of a series of wire strands, or, alternatively, to the individual strands as a whole, and closing the strands into a rope in a closing die while passing a nonfoamable plastic material into the closing die. Sealed plastic foam impregnated wire strands can be made in the same manner by passing nonfoamable plastic material into the stranding die during fabrication of the strand.

    Abstract translation: 一种耐腐蚀绳索，其中单个股线用塑料泡沫浸渍剂密封并用致密的未发泡塑料材料包围，是通过将可发泡塑料施加到一系列线股的单根丝线上，或者替代地，将各股线 作为整体，并且在将不可发泡的塑料材料通入封闭模具中时，将线束封闭在闭合模具中的绳索中。 密封的塑料泡沫浸渍的金属丝股线可以以相同的方式通过在制造线材期间将不可发泡的塑料材料通过绞合模具制成。
