  • Patent number: 9175693
    Abstract: An article of manufacture having a nominal airfoil profile substantially in accordance with Cartesian coordinate values of X, Y and Z set forth in a scalable table, the scalable table selected from the group of tables consisting of TABLES 1-11, wherein the Cartesian coordinate values of X, Y and Z are non-dimensional values convertible to dimensional distances by multiplying the Cartesian coordinate values of X, Y and Z by a number, and wherein X and Y are coordinates which, when connected by continuing arcs, define airfoil profile sections at each Z height, the airfoil profile sections at each Z height being joined with one another to form a complete airfoil shape.
    Type: Grant

  • Patent number: 9145777
    Abstract: An article of manufacture has a first component configured for use with a turbomachine. The first component is configured for attachment to a second component, and reduces the possibility of attachment with an undesired third component by modification of a characteristic of the first component. This modification is matched by a complementary characteristic of the second component. The first component has a nominal airfoil profile substantially in accordance with Cartesian coordinate values of X, Y and Z set forth in a scalable table selected from the group consisting of TABLES 1-11. Cartesian coordinate values of X, Y and Z are non-dimensional values convertible to dimensional distances by multiplying by a number. X and Y are coordinates which, when connected by continuing arcs, define airfoil profile sections at each Z height. The airfoil profile sections at each Z height being joined with one another to form a complete airfoil shape.

  • Patent number: 8556588
    Abstract: An article of manufacture is disclosed. The article may have a nominal profile generally in accordance with Cartesian coordinate values of X, Y and Z set forth in TABLE A. X and Y may correspond to distances in inches which, when connected by smooth continuing arcs, define airfoil profile sections at each distance Z in inches, the airfoil profile sections at the Z distances being joined smoothly with one another to form a complete airfoil shape.

  • Patent number: 5890177
    Abstract: A document can be collaboratively edited by multiple editors by providing each editor with a separate copy of the document. Each editor then edits his own document copy using an editing application program, such as a word processor, to produce an edited copy. The edited copies are then retrieved and compared and a single marked-up document is created in which sections (for example, paragraphs) of the original document and corresponding sections of each of the edited documents (with changes from the original document indicated) are displayed in physically adjacent locations of the display screen. The displayed sections contain both edited and duplicated, unedited text. A set of "consolidation" tools are provided to quickly transfer edits between the physically adjacent areas of the screen and to make, or accept, edits made by any of the editors. A final document copy is made by eliminating the duplicate text in the sections.
