20130298693 | METHOD OF FATIGUE TESTING A COMPONENT - A method of fatigue testing a component comprising the steps of machining a channel of predetermined depth and predetermined width in a surface of a component, applying a salt solution into the channel in the surface of the component and heating the component to a suitable temperature to evaporate the solvent from the salt solution to deposit the salt in the channel in the surface of the component, placing the component in an atmosphere containing air and sulphur dioxide at a predetermined temperature for a predetermined period of time to precondition the grain boundaries, and fatigue testing the component. The method is useful for determining the fatigue life of gas turbine engine discs or gas turbine engine rotor blades particularly the firtree shaped disc posts or the firtree shaped rotor blade roots. | 11-14-2013 |

20150305342 | PROCESS AND COMPOSITION FOR KILLING SPORES - This invention relates to a process and an aqueous composition for killing spores. The process comprises contacting the spores with the aqueous composition for a sufficient period of time to effect a desired reduction (e.g., at least a 4 log reduction) in the number of spores capable of reproduction, metabolism and/or growth. The aqueous composition comprises water, peracetic acid and hydrogen peroxide. The concentration of peracetic acid in the water may be in the range from about 0.001 to about 60% by weight, or from about 0.001 to about 0.5% by weight. The weight ratio of peracetic acid to hydrogen peroxide may be in the range from about 0.001 to about 0.5. | 10-29-2015 |
20150305343 | PROCESS AND COMPOSITION FOR KILLING SPORES - This invention relates to an aqueous composition and a process for killing spores. The process may comprise contacting the spores with the aqueous composition for a sufficient period of time to effect a desired reduction (e.g., at least a 4 log reduction) in the number of spores capable of returning to vegetative growth. The aqueous composition may comprise water, an antimicrobial agent (e.g., peracetic acid) and a peroxide (e.g., hydrogen peroxide). The process may be a two-step process involving the use of a first aqueous composition, which may comprise water and the peroxide, and a second aqueous composition which may comprise water and the antimicrobial agent. | 10-29-2015 |
20150305344 | DECONTAMINATION OR STERILIZATION PROCESS - This invention relates to a decontamination or sterilization process wherein spores are killed, comprising: forming droplets of an aqueous composition comprising water and a peroxide, the aqueous composition having a concentration of peroxide in the range from about 0.01 to about 14% by weight; vaporizing the droplets to form a sporicidal vaporous mixture; and contacting the spores with the sporicidal vaporous mixture for a sufficient period of time to effect at least a 4 log reduction in the number of spores capable of returning to vegetative growth. | 10-29-2015 |
20150306266 | PROCESS FOR DECONTAMINATING OR STERILIZING AN ARTICLE - This invention relates to a a process for decontaminating or sterilizing an article contaminated with spores.

20150083419 | FRACTURING VALVE AND FRACTURING TOOL STRING - A fracturing valve comprising a tubular mandrel having a through bore continuous with a tubing string, and a frac window through the side of the tubular mandrel. An outer sleeve is radially disposed around the tubular mandrel. The outer sleeve includes a sleeve port in a sidewall. The tubular mandrel slides relative to the sleeve by application and release of set down weight on a coiled tubing string. When the valve is closed, there is no fluid communication from the tubing string out of the frac window. When the valve is open, fluid communication from the tubing string is enabled. The valve may be installed in a downhole tool having a perforation device. The tool string can be used with one sealing element as the tool is pulled up the hole isolating lower perforations, or with two sealing elements to allow pin-point treatments isolating perforations both up and downhole. | 03-26-2015 |
