20090304942 | WIRE-ARC SPRAYING OF A ZINC-NICKEL COATING - A zinc-nickel substrate is applied to a component by using a zinc-nickel wire formed with between about 8 to 20 percent nickel and between about 80 to 90 percent zinc. This formed zinc-nickel wire is held in a two wire electric arc spray system to spray the zinc-nickel substrate on the component, such as an aircraft part, while operating the two wire electric arc spray system within a specific range of operating parameters. | 12-10-2009 |

20100188734 | Multi-fibre arrangement for high power fibre lasers and amplifiers - An optical fibre arrangement has at least two optical fibre sections, each optical fibre section defining an outside longitudinally extending surface. The outside longitudinally extending surfaces are in optical contact with each other. The invention further provides for an amplifying optical device have an optical fibre arrangement as just described, and a pump source. The amplifying optical device is configured such that the pump source illuminates the amplifying optical fibre. A amplifying arrangement is also disclosed. The amplifying arrangement includes a plurality of amplifying optical devices as just described, and each amplifier also has at least one input fibre and a first multiplexer connected to the input fibre. Each amplifier is configured such that at least one of the amplifying optical fibres is connected to the first multiplexer. The amplifying arrangement also has a second multiplexer connected to each of the first multiplexers. | 07-29-2010 |
20120314279 | Multi-fibre arrangement for high power fibre lasers and amplifiers - An optical amplifier includes at least one pump source and an optical fibre cable which includes an amplifying optical fibre and a pump optical fibre that are defined by respective lengths. The amplifying optical fibre and the pump optical fibre are coated with a common coating along a portion of their respective lengths, and the fibres are in optical contact with each other along a coating length within the common coating. The common coating has a refractive index which is lower than a refractive index of a cladding material of the pump optical fibre. The fibres are made substantially from glass. The amplifying optical fibre includes a core and a cladding, and is doped with a rare earth dopant. The pump optical fibre is defined by a first end and a second end, the first end of the pump optical fibre being connected to the pump source. | 12-13-2012 |
