  • METHOD OF REPAIRING A COMPONENT
    Publication number: 20120211548
    Abstract: A method of repairing a component comprising: removing a damaged portion of the component to expose a region of the component; providing a patch having a rim exceeding the dimensions of the exposed region; placing the patch on the exposed region of the component such that the exposed region is covered by the patch and the rim is spaced apart from the exposed region; joining the patch to the component around the rim of the patch; and diffusion bonding the patch and the component together. The rim may be spaced apart from the exposed region such that the step of joining the patch to the component does not affect the exposed region. The method may further comprise machining a recess in the damaged region of the component.

  • WASTE INK RECLAMATION APPARATUS FOR LIQUID INK RECIRCULATION SYSTEM
    Publication number: 20120200636
    Abstract: An ink reclamation receptacle receives ink purged from an inkjet printing apparatus. Ink in the reclamation receptacle wets a porous membrane positioned in the reclamation receptacle, and flows into a flow channel. Negative pressure applied to a port that is placed in fluid communication with the flow channel withdraws ink from the flow channel for use in the inkjet printing apparatus, while ink wetting the pores in the membrane resists a flow of air into the flow channel.

  • METHOD FOR BEAM WELDING ON COMPONENTS
    Publication number: 20120097645
    Abstract: In a method for beam welding on components with a laser beam or electron beam generated by a beam source, the heat treatment of the welded component required to remove stresses is integrated into the welding process. In a work cycle combined with the welding process, a regulated heat supply to a selected region takes place, according to its residual heat resulting from the welding process and the predicted stresses in that region, using the residual heat remaining from the welding process following the welding process from the same or other beam source(s). The welding region is cooled in a controlled manner, so that welded components which are likely to be subject to high stress in use, provided for example for a aircraft engine, can be made available without inherent stresses and with the desired microstructure in a single—combined—work step.

  • SURFACE TREATMENT DEVICE
    Publication number: 20120071069
    Abstract: A surface treatment device includes an enclosure which has an opening through which the leading edge of an aerofoil passes. A sealing element is provided on the enclosure to seal the device to the surfaces of the aerofoil. An abrasive is located within the enclosure and two fluid openings are also provided through which a chemical accelerant can be pumped. In operation the enclosure is oscillated relative to the component so that material is abraded. Whilst the enclosure is oscillated a chemical accelerant is simultaneously pumped through it. The device allows for the local application of a surface treatment on a component.

  • OXIDATION STATE SENSORS AND METHODS FOR TRANSITION METAL ALLOYS
    Publication number: 20120040467
    Abstract: The present invention is concerned with a method of discriminating between, in a surface of a transition metal alloy, transition metals in different oxidation states using surface sensor molecules adapted to associate selectively with one of the transition metals. In particular, the present invention provides a method of identifying degradation in aircraft components such as turbine blades, engine casings and aerofoils. In embodiments, a surface sensor molecule comprising an oxidation state discriminating group, such as an imidazole, and a fluorescein probe is applied in aqueous solution to the surface of a service-run Ni alloy aircraft component. The sensor molecule selectively associates with transition metals in oxidation states greater than zero such that fluorescence imaging can be used to identify areas of degradation.

  • LIQUID INK DELIVERY SYSTEM INCLUDING A FLOW RESTRICTOR THAT RESISTS AIR BUBBLE FORMATION IN A LIQUID INK RESERVOIR
    Publication number: 20120026255
    Abstract: A fluid ink delivery system includes a receptacle positioned proximate to a plurality of inkjet ejectors, and an ink supply in fluid communication with the receptacle. Ink held in the receptacle may be withdrawn under negative pressure by a pump in the ink supply. A flow restrictor in fluid communication with the pump limits the negative pressure level applied by the pump to be less than a pressure that draws air across a porous member in the receptacle.

  • Actuator
    Patent number: 8043045
    Abstract: Actuators utilising shape memory alloy materials are known with regard to gas turbine engines. Such shape memory alloys have been used with respect to deformation provided in vanes and blades as well as nozzle elements in order that variations can be made in engine configuration dependent upon thermal cycling. Unfortunately, pedestals in order to provide spacing between the shape memory alloy and an antagonistic bias has resulted in uneven stress distribution as well as a higher thermal mass for the shape memory alloy. An uneven stress distribution will limit operational life whilst a higher thermal mass will result in slower reaction times. By separation of the shape memory alloy or material from its antagonistic bias through use of a slide element, a reduction in thermal mass is achieved and, more importantly, stress differentiation across the actuator is reduced.

  • METHOD OF MANUFACTURING A COMPONENT
    Publication number: 20110253680
    Abstract: A method of manufacturing a component. The method includes the steps of heating a working region of a substrate with a heating means; directing a material into the working region to bring the material into a temporary molten state, and depositing said material on the substrate such that when the material solidifies it forms at least part of the component. The heating means power output, stand off, orientation, speed and direction of travel relative to the substrate are adjustable and controlled throughout the material deposition process to control the shape and/or size of the working region to thereby control the distribution and rate of heat delivery to the substrate.
