  • Publication number: 20190353051
    Abstract: A turbine engine including a first static structure comprising a first material defining a first thermal expansion coefficient and a second static structure comprising a second material defining a second thermal expansion coefficient different from the first thermal expansion coefficient. The first static structure and the second static structure are together disposed in adjacent arrangement along a load direction. The first static structure and the second static structure together selectively define a gap therebetween along the load direction based at least on a load difference between the first static structure and the second static structure.

  • Patent number: 10467338
    Abstract: Systems and methods for receiving a first string from a user in a user session, tracking a first response to the first string from the user in the user session, receiving, after receiving the first string, a second string from the user in the user session, the second string having a character operator difference that is below a threshold number from the first string, tracking a second response to the second string from the user in the user session, associating the first string with the second string in response to the second response comprising a higher number of responses as compared with the first response, removing the association between the first string with the second string in response to the second string being a correction of the first string, and correcting, using the association, user input by replacing a portion of the user input that matches the first string with the second string.

  • Patent number: 7597237
    Abstract: A process is disclosed that creates a high shear rate in a workpiece using a head including a ring-shaped rotatable shoulder, a first pin and a second pin, both pins extending downwardly relative to the shoulder. The process includes coupling the workpiece to a table and rotating the first pin and the second pin in the same direction, wherein the first pin has a diameter, wherein a gap between the first pin and the second pin is less than the diameter. The head is plowed through the workpiece with the shoulder bearing downwardly against the workpiece and the first and second pin disposed in the first and second workpieces. The first pin rotates in a direction opposite the direction of the second pin in the gap to create a high shear rate of the workpiece within the gap.

  • Publication number: 20080000557
    Abstract: A method and apparatus for producing ultra-fine grained magnesium metal alloy material sheets. The apparatus molds and rapidly solidifies a metal alloy material to form a fine grain precursor. The precursor is then subjected to deformation strains that alter the grain structure of the precursor so as to form a ultra fine grained structure in sheet form. The sheet form may then be subjected to superplastic forming to form a net shaped article.

  • Publication number: 20060283529
    Abstract: A method and apparatus for producing ultra-fine grained metal material sheets. The apparatus molds and rapidly solidifies a metal material to form a fine grain precursor. The precursor is then subjected to a series of successive alternating tensile and compressive strains that alter the grain structure of the precursor so as to form a ultra fine grained structure in sheet form. The sheet form may then be subjected to superplastic forming to form a net shaped article.

  • Publication number: 20060218030
    Abstract: Work item rules for a work item tracking system are provided. Work item rules may be accessible, usable and subject to interpretation by multiple software entities. Further, work item rules may be configured to be subject to creation and change by users, for example, by exposure to users through a user interface. A work item rule may specify an identifier by which the abstraction can be identified and/or a name, and may specify, or be indicative of, a condition and an action to be taken if the condition is satisfied. In response to a first user action affecting a first work item rule, one or more work item rules corresponding to the first user and/or the first work item may be determined. The one or more work item rules then may be interpreted, and the user action responded to based on the interpretation.

  • Publication number: 20060123432
    Abstract: Techniques for enabling inter-subsystem resource sharing are provided. The techniques include providing an RPC client on a first subsystem for acting as a proxy for a resource of a second subsystem. When the first subsystem receives a request from an application to access the resource, the RPC client may invoke a function of an RPC server associated with the second subsystem. The RPC server may load the resource on the second subsystem. The RPC client may then act as a proxy for the resource.
