摘要： A method, apparatus and system for improving reverse oscillating lay (ROL) consistency during an optical cable manufacturing process. A torque capstan receives an optical fiber cable from an ROL machine that places reverse-oscillating lay on the core of an optical cable, but also generates some undesirable fluctuating back-tension in a direction opposite a direction in which the optical fiber cable is being pulled during manufacturing of the optical cable. The optical cable comprises a plurality of subunit cables. A drive system coupled to the torque capstan is controlled by a control system in such a way that the torque capstan applies a certain amount of force to the optical cable in a direction substantially parallel to the direction in which the optical cable is being pulled during manufacturing. The certain amount of force applied to the optical fiber cable reduces undesirable fluctuating back-tension placed on the optical cable during the manufacturing process, thereby improving reverse oscillating lay (ROL) consistency, which improves the quality of the manufactured optical cables.

摘要： A torque capstan is provided for use in an optical fiber cable manufacturing process which enables reverse oscillating lay (ROL) length to be maintained. The torque capstan comprises a first portion having at least two pulleys rotationally mounted thereon, a second portion having at least two pulleys rotationally mounted thereon, and first and second drive belts mounted on the pulleys of the first and second capstan portions, respectively. Rotational motion is imparted to the first and/or second drive belts through a drive system that is coupled to a drive pulley of at least one of the first and second capstan portions. Rotation of at least one of the drive pulley(s) causes the respective drive belt to rotate in a direction parallel to, or substantially parallel to, a direction in which an optical fiber cable being manufactured in the optical fiber cable manufacturing process is being pulled. Contact between the drive belts causes the drive belts to rotate in the same direction. At least one of the first and second drive belts has a longitudinal groove formed therein that is parallel to, or substantially parallel to, the direction in which the optical fiber cable is being pulled. The belts grip and pull/push the cable in such a way that the ROL length is maintained over a length of the optical fiber cable, thus improving the quality of the manufactured optical fiber cables.

摘要： The present invention relates generally to a mechanism of a contact system for circuit breakers. More particularly, the invention encompasses a mechanism for a rotary double-break contact system, which enables a direct transfer of torque from stored energy components, such as, springs, to the contact arm in the ON-position (contacts closed) without using intermediate cam surface. The mechanism described in the invention also ensures reliable locking of the contact arm in the blow-off position using stationary means that are integral with or fixed to a crossbar module. This invention enables to achieve significant reduction or even to eliminate friction at certain critical interfaces between the contact mechanism components, thus, reducing or potentially eliminating hysteresis, and improving performance consistency, and also eliminating mechanism performance dependency on wear level and condition of an intermediate cam surface. An additional feature of this invention is a reduction of a loss of contact torque/force during over-travel in the ON position when the fixed and/or moveable contacts erode. Configurations described in this invention may also feature physical protection for the moving components of the contact mechanism assembly from flying particles resulting from short circuit shots.
