Abstract: An ultrasonic probe is used to inspect wheel and bucket dovetails of turbines for cracks in the material surrounding pinholes and pins securing the buckets and wheel to one another. Only a minimum number of pins, for example, one of three radially aligned pins securing the bucket and wheel dovetails to one another at every other circumferential position of the pins about the wheel may be removed. A phased array ultrasonic probe is inserted into the excavated pinhole and provides a circumferential scan of the finger dovetails to detect cracks in adjacent pinholes. As an alternative, a probe having one or more piezoelectric elements providing one or more radial beams may be mechanically rotated in the pinhole. Statistical sampling may be used as an indicator of crack formation. Thus, in situ inspection is performed without removal of buckets from the wheel and with only a minimum number of pins being removed.

Abstract: A method for applying design for reliability into design for Six Sigma is described. The method includes establishing an appropriate model for reliability as a function of time; determining a reliability transfer function; calculating defects per opportunity per unit of time; entering said defects per opportunity per unit of time into a calculation of value of sigma; selecting one or more noise factors likely to have an impact on reliability; and performing a closed form analytical solution of said impact on reliability using a Monte Carlo analysis. The noise parameters may include one or more assumptions of the hours of usage per year, temperature of use, material quality, part quality, layout of components, extrinsic stresses, supplier quality, interconnection quality, test coverage, shipping damage, installation errors, errors in instructions, customer misuse or other noise factors beyond the control of the designer.

Abstract: A process for producing polycarbonate is disclosed. Accordingly a pre-reaction mixture containing a bis(hydroxyaryl) compound and a diaryl carbonate is formed and introduced through the top of a reactive rectification column under condition calculated to bring about a reaction. The resulting hydroxyaryl is eliminated and diaryl carbonate in vapor form is introduced at the bottom of the reactive rectification column.

Abstract: An independently rotatably mounted container may be used, by agitating the contents thereof, in the performance of a multi-component reaction or assay, by selective rotation of said container in the presence of adjacently mounted component containers which are not rotated. Such a principle may be applied in suspending solid phases in, for example, automated immunoassay apparatus or in reconstituting freeze dried reagents. Selective rotation has a number of advantages including gentleness to components and greater efficiency and reliability.
