Abstract: The present invention relates to a device for supplying extra-long lengths of continuous metal strip material to metal processing and/or manufacturing equipment. The device has a central member adapted to receive a plurality of coils of strip material and free to rotate about its longitudinal axis and a plurality of retractable spacing elements for separating adjacent coils of material without interfering with the material feed operation. To insure a supply of material sufficient to enable operation of the equipment for long periods of time, the coils stacked on the central member are interconnected.

Abstract: The present invention relates to a process and apparatus for fabricating optical fiber cables having improved hermeticity. The optical fiber cables are formed by first reducing the water content of the buffer material surrounding each optical fiber. Thereafter, the dried optical fiber(s) are encapsulated into a metal or metal alloy tube. After fiber encapsulation, the tube may be sealed to prevent the ingress of moisture and/or water from the surrounding environment.

Abstract: The improved machinability of standard Alloy 688 and modified 688 is achieved through the addition of lead to the alloy. This machinability improvement in Alloy 688 is not achieved at the detriment of the well-known strength of Alloy 688.

Abstract: The improved high temperature softening resistance of Alloy 688 and modified 688 is obtained by the addition of niobium to the alloys. These particular alloy systems not only exhibit resistance to high temperature softening, but also exhibit improved stress corrosion and stress relaxation resistance properties. All of these properties are attained without any loss in the high strength properties of the base alloy systems.
