Abstract: A method and an apparatus for correcting the strip travel when rolling strips in at least one roll stand, wherein measurement values relevant for the tensile stresses are measured on opposite sides of the exiting strip. Subsequently, the difference of the tensile stress values is computed in a control circuit as an actual value and the strip travel is corrected when the actual value deviates from a desired value by changing the roll adjustment of the at least one roll stand. The tensile stress values are measured at that strip portion which travels over a tension measuring device which, seen in the strip travel direction, is arranged behind the roll stand and transversely of the strip.

Filed: 1998-05-04
Abstract: A target (1) for sputtering is subjected to a surface treatment process and special packaging after target (1) manufacture for improved sputtering performance and process and yield by reducing particulates. The sputtering target (1) is first surface treated to remove oxides, impurities and contaminants. The surface treated target (1) is then covered with a metallic enclosure (5) and optionally, a passivating barrier layer. The metallic enclosure (5) protects the target surface from direct contact with subsequently employed packaging material such as plastic bags (23), thereby eliminating source of organic materials during sputtering operations. The surface treatment of the target (1) removes deformed material, smearing, twins, or burrs and the like from the target surface, reducing "burn-in" or sputter conditioning time prior to production sputtering of thin films.

Abstract: A system for rerouting misrouted calls between call centers has multiple call centers all connected by digital link to a central rerouter, which maintains a data list of a unique pool of destination numbers assigned to each of the call centers. The central rerouter sends rerouted calls to destination numbers in the destination number pool for each call center in a sequential manner such that any destination number in the pool for any call center, once used, is not used again until all of the remaining destination numbers in the pool for that call center are used once each. In a preferred embodiment call centers are interconnected by private lines, and rerouted calls are sent over the private lines.

Title: Contact configuration in a modular jack
Inventor: BOGESE STEPHEN B II
IPC: H01R24/58
Filed: 1999-11-30
Abstract: An improved modular telephone-style jack featuring an improved contact configuration. The modular jack directly couples a modular male plug to a printed circuit board.  The jack features a contact having a lower linear beam in combination with an glide dimple so that the contact can extend forwardly once its upward movement during mating with a modular plug is restrained. The lower linear beam is lifted during engagement and remains lifted while mated with a contact in a modular male plug. As a result of lifting, the free end of the contact also lifts in a typically unrestrained manner. However, the space above a mounted jack may be limited by multiple boards stacked in close proximity or the jack may be adjacent a mounting bracket located around the jack. If the space above the jack is limited, the contact will only be able to lift to a height less than its unrestrained lifted height. In one embodiment, the glide dimple is an arcuate shape whose open side faces downward so that its uppermost curved surface is tangent to the underside of the cover or upper wall of the modular jack. As the cover lifts in concert with the free end of the contact, when the cover hits a physical stop and thus is restrained from further lift, the glide dimple slides forward along the underside of the cover. The contact extends forward as the contact in the male plug lifts the lower linear beam further to a fully mated position so as to absorb the additional lift via extension in a direction generally parallel with the lower linear beam.
