Publication number: 20060181696Abstract: A system and methods for automating the testing of optical fiber are described. According to one aspect of the present invention, an automated conveyor system moves spools of optical fiber contained on pallets from testing station to testing station. According to another aspect of the present invention, a single spool is carried by a specially designed pallet. According to another aspect of present invention, an apparatus automatically strips, cleans, and cleaves the fiber ends once the spool reaches the apparatus. The fiber ends are then automatically manipulated into the appropriate location for a predetermined test to be performed. According to another aspect of the invention, an apparatus automatically acquires a sample length of the optical fiber and strips, cleans, and cleaves the fiber ends of the sample. The sample length of the optical fiber is then manipulated into the appropriate location for a second predetermined test to be performed.Type: ApplicationFiled: March 31, 2006Publication date: August 17, 2006Inventors: Erling Anderson, Richard Blazek, William Kish

Patent number: 6125133Abstract: A method for providing main gas into a pool of molten metal, which is particularly useful for use in an electric arc furnace. The method employs combustion of secondary oxygen with fuel to form a flame envelope around a main gas stream which protects the main gas from entrainment of ambient gases as it passes through the headspace of the furnace. This enables the gas to retain to a substantial degree its original force upon injection into the headspace and thus may be injected into the furnace at a safe distance from the molten metal surface while still achieving substantially complete penetration into the molten metal.Type: GrantFiled: March 18, 1997Date of Patent: September 26, 2000Assignee: Praxair, Inc.Inventors: Pravin Chandra Mathur, Ronald Joseph Selines, John Erling Anderson
