A method is taught for joining a wrought alloy material to a cast alloy, so as to obtain a joint having superior structural integrity. A cast nickel-base superalloy part may be bonded to a wrought nickel-base superalloy part, for example, by positioning a suitable part or blank of said wrought superalloy adjacent to the cast superalloy part, applying a local bonding force to the interface while locally heating the interface to a temperature which causes localized softening, metal flow, and bonding, removing said bonding force, and subjecting the bonded assembly to a local or isothermal heat treatment so as to minimize distortion, optimize properties, and stress relieve the bonded assembly. This method may be used, for example, for the repair or replacement of vane assembly retaining lugs, whereby a replacement lug of a wrought alloy is solid state bonded to the vane assembly in place of the previous retaining lug.

A method is taught for repair of holes in superalloy or titanium materials by using plugs of the same or similar material and heat treatment, whereby a fully recrystallized joint interface is achieved between the plug and the walls of the hole.
摘要:
A system and method for enabling a user to transact an anonymous on-line transaction, wherein a form of on-line payment is requested at a transaction interface is disclosed. The method may include providing an anonymous user interface that enables a user to initiate an on-line payment, accessing a first profile comprising user data when the user activates the form of on-line payment, generating a second profile linked to the first profile wherein, the second profile comprises anonymous data, and communicating the anonymous data from the second profile to the transaction interface to enable completion of the transaction.
摘要:
A method of repairing a part, such as a rotating disk/drum rotor of a gas turbine engine. The method includes: heating a contact area of a wrought material and a contact area of a wrought part; and pressing the contact area of the material against the contact area of the part to bond the parts. A method of making a rotating part of a gas turbine engine, comprising: heating a contact area of a wrought material and a contact area of a wrought part; and pressing the contact area of the material against the contact area of the part to bond the parts. The methods may include a subsequent heat treatment to provide the desired strength properties to the joint between the material and the part.
摘要:
A rotor support structure for a gas turbine engine comprises a rolling element bearing adapted to carry the rotor, a structurally strong ring adapted to carry the rolling element bearing, and two pairs of supporting struts for the ring, extending substantially tangentially from the ring, each pair joining at a mounting, the two mountings being diametrically opposed with respect to the ring.

A basic architecture for managing digital identity information in a network such as the World Wide Web is provided. A user of the architecture can organize his or her information into one or more profiles which reflect the nature of different relationships between the user and other entities, and grant or deny each entity access to a given profile. Various enhancements which may be provided through the architecture are also described, including tools for filtering email, controlling access to user web pages, locating other users and making one's own location known, browsing or mailing anonymously, filling in web forms automatically with information already provided once by hand, logging in automatically, securely logging in to multiple sites with a single password and doing so from any machine on the network, and other enhancements.
