Abstract: A method for refurbishing turbine engine vanes in which the airfoils are removed and replaced. The original configuration of the vanes can be modified from a single casting or welded pair to a multi-piece component assembly comprising individual airfoil segments attached to the inner and outer platforms. The component assembly allows replacement of airfoils and/or platforms with improved castings in the form of improved alloys, improved physical geometry, or both. Modifications can be made in the vane class area without the need to modify the airfoil contour by brazing or other contour alteration processes. According to the method, the platforms are separated from the airfoils, the openings in the platforms are sealed, new airfoil sockets are cut into the platforms, and the vane is reassembled.

Abstract: A method of refurbishing turbine engine vanes in which an alloy blend of a cobalt based superalloy and a nickel based superalloy corresponding to the base material of the turbine vane cobalt platform and the base nickel material of the replacement turbine vane airfoils is laser clad to the gaspath surfaces of the turbine vane platform. Laser cladding with the alloy blend allows the use of replacement airfoils with improved castings in the form of improved nickel based superalloys, and allows a coating to be uniformly applied to the gaspath surfaces of the vane. According to the method, the platforms are separated from the airfoils and laser clad with a blend of cobalt based superalloy and nickel based superalloy. The vane is then reassembled using the laser clad platform and at least one replacement airfoil.

Abstract: A system for detecting the envelope of a signal is provided. The system includes a first envelope detector generating a first envelope signal of an input RF signal, such as an envelope signal representing the positive peak envelope of the input RF signal. A second envelope detector generates a second envelope signal of the input RF signal, such as an envelope signal representing the negative peak envelope of the input RF signal. A signal combiner receives the first envelope signal and the second envelope signal and generates an even-order harmonic compensated envelope signal, such as by compensating for the difference between the positive peak envelope and the negative peak envelope.

Abstract: Method and architecture for facilitating payment to e-commerce merchants via a payment service. The method enables consumer users of an electronic storefront hosted by a merchant to make purchases via the payment service, wherein interactions between the electronic storefront and the payment service are transparent to the user. In response to a user check-out request, the user's browser is directed to a payment service web site. Information from which authorization for use of the payment service may be determined is passed to the payment service. The payment service then returns the browser to a selected check-out flow hosted by the electronic storefront, wherein the check-out flow provides an option to use the payment service if the user and merchant are authorized to do so, otherwise the check-out flow does not include the payment service option. In one embodiment, an application program interface (API) provided by the payment service is employed by the electronic storefront to facilitate transactions with the payment service.

Abstract: The seam welder conductive mechanism is the main part of the resistance seam welding machine. When the electrode wheel rolling on the welded parts, the Seam welder conductive mechanism will withstand the high press of electrode force and pass the high welding current from welding transformer to the electrode wheels of seam welding machine. Because of these two characteristics the following factors must be considered during the design of seam welder conductive mechanism. First of all, in order to withstand the high press of electrode force two bearings are introduced in the mechanism, the bearing should be lubricated and also isolated from the welding current in order to get long working time without damaging the bearing. Second of all, in order to pass the high welding current, the conductive pair with relative motion must be keep conduction all the time with certain surface pressure and lubrication, the conductive pair without relative motion must be keep conduction all the time with big surface pressure. Because of the high current pass through the conductive mechanism must be cooled with water during working. This is a mechanism equipped with water cooling for Electrode, main shaft, and Silver-plate conductive pads.
