Abstract: A system for tensioning and locking a safety strand to a number of sequentially arranged stanchions is provided. The system includes tensioning means for applying a tensile force to one end of the safety strand when the safety strand is passed through a passage bore of each of the sequentially arranged stanchions and the other end of the safety strand is secured to an immovable object. Locking mechanisms are provided that each include a cable cradle having a receiving channel for receiving a portion of the safety strand, a clamping arrangement for engaging and trapping the portion of the safety strand within the receiving channel, and a device for securing the cable cradle and clamping arrangement to a stanchion. The cable cradle and securing device are configured so that when the cable cradle is secured to the selected stanchion, the receiving channel is in registry with the passage bore.

Abstract: A system for tensioning and locking a safety strand to a plurality of sequentially arranged stanchions is provided. Each stanchion has a stanchion cross section and a passage bore adapted for slidable passage of the safety strand therethrough. The system comprises tensioning means for applying a tensile force to a first end of the safety strand when the safety strand is disposed through the passage bore of each of the sequentially arranged stanchions and a second end of the safety strand is secured to an immovable object. The system further comprises a plurality of locking mechanisms.

Abstract: A method for manufacturing machining tools out of composite powdered metal which is first formed to approximate the desired shape of the machining tool; then bonded metallurgically; and machined to the desired finished shape. Desirably, the forming step employs at least two distinct powdered metals, the first formed to the outer shape over the portion of the tool that interfaces with the work piece and selected to exhibit the desired hardness and wear-resistance properties. The second material supports the hollow form of the first material and includes a shank to interface with the machine that the tool will be employed with. The second material is chosen to exhibit the desired ductility, surface hardness, abrasion resistance and reduced cost. Additional materials can be used for different facets of the tool to obtain an optimum balance of long life, efficient operation and low cost.
