Abstract: A rolled metal strip which is free of torsion and on which a superior gloss is obtained by a combination of cross rolling and parallel rolling upon cold rolling a metal strip and by rolling the material in a parallel rolling manner in either at least the final stand (in the case of a tandem mill array) or at least the final pass (in the case of a single stand mill such as a reversible mill or the like). If necessary, the metal strip is preliminarily rolled by cross rolling at a rolling reduction rate of over 5% and then cold rolled by either parallel rolling or a combination of cross rolling and parallel rolling.

Abstract: In a overhead power transmission system, a sensing member for detecting condition of the overhead power transmission or distribution lines or the ground wire is secured to an anchor and clamp member for anchoring and clamping the power line or overhead ground wire so as to prevent undesired movement of the sensing member.

Abstract: An apparatus for changing the direction of travel of a web-like material without inverting the front and rear surfaces of the web-like material is improved in that a plurality of guide rotors are disposed on each of a plurality of spiral curves along an imaginary conical surface so as to be rotatable about axes intersecting at right angles with the corresponding spiral curve on the imaginary conical surface, and a conical surface formed by an enveloping surface of these guide rotors is used as a traveling path of the web-like material, whereby shortcomings inherent in such apparatus in the prior art can be eliminated.

Abstract: Structure for connecting overhead earth wires with an optical fiber unit is proposed which comprises a protecting member for protecting the optical fiber unit from deformation. The protecting member is formed with a through hole for passing the optical fiber unit and with longitudinal grooves to receive the conductors.

Abstract: A tandem rolling mill train for rolling metal plate or sheet includes a plurality of crossed-roll type rolling mill stands. The work rolls on at least two of the crossed-roll type rolling mill stands are respectively slanted in opposite directions so that the widthwise shear deformation developed on the upstream crossed-roll type stand is reduced by the widthwise shear deformation caused on the downstream crossed-roll type stand.
