Publication number: 20090000392Abstract: A simulating circuit (2), for testing a transit-time flowmeter (1) according to an embodiment of the invention, comprises an interface circuit (20) connecting with the transit-time flowmeter. The interface circuit receives driving signals from the transit-time flowmeter and generates a trigger signal on a rising or falling edge of the driving signals. An oscillator (21) outputs a clock signal. A delay generator (221) generates a preset time delay. A Digital to Analog Converter (DAC, 25) retrieves preset digitalized waveform. The DAC is enabled by the oscillator on ending of the preset time delay and converts the preset digitalized waveform into analog waveform output. The analog waveform output is sent back to the transit-time flowmeter, and thus a transit time or and a waveform through flowing fluids is simulated.Type: ApplicationFiled: August 1, 2007Publication date: January 1, 2009Applicant: GENERAL ELECTRIC COMPANYInventors: Hua Zhou, Yikang Gu, Thomas James Batzinger, Baoming Huang, Xiaolei Shirley Ao, Jeffrey Tilden

Patent number: 6909988Abstract: A process for positioning at least one defect in a billet being forged into an article is described. The size and location of the billet is first determined, using a non-destructive test such as ultrasonic inspection. The movement of the defect under selected forging conditions is then predicted, using a finite element analysis model. The billet can then be positioned and forged under conditions which cause the defect to move to a non-critical area of the article. In this manner, a billet which might otherwise be discarded or set aside can often be retained for a useful purpose. Related articles are also described.Type: GrantFiled: October 15, 2002Date of Patent: June 21, 2005Assignee: General Electric CompanyInventors: Thomas James Batzinger, Michael Francis Xavier Gigliotti, Jr., Bernard Patrick Bewlay, Shesh Krishna Srivatsa

Patent number: 6888347Abstract: An omnidirectional eddy current probe includes a number of sense coils arranged in a stack having a principal axis. At least two of the sense coils are rotationally skewed about the principal axis relative to one another. The sense coils are operatively connected to each other and a drive coil is also positioned in the stack. An impulse through the drive coil induces a magnetic influx through a conducting material specimen having a surface, thereby generating eddy currents on the surface. Secondary magnetic field generated from the eddy currents produces corresponding signals in the sense coils, and the signals are then analyzed for the possibility of surface flaw in the conducting material.Type: GrantFiled: September 12, 2003Date of Patent: May 3, 2005Assignee: General Electric CompanyInventors: Thomas James Batzinger, Shridhar Champaknath Nath, Curtis Wayne Rose

Patent number: 6789427Abstract: A method for inspecting a component includes exciting a number of transducers forming an array to produce an ultrasonic transmission beam (beam) focused into the component. The array and the component are separated by a standoff. A number of echo signals are generated using the transducers, and the echo signals are processed in a number of channels. The processing includes both dynamical focus and providing a dynamic aperture on receive, both of which compensate for refraction of the beam at the component/standoff interface. A single-turn inspection method includes: (a) positioning the array facing the component, (b) exciting the transducers, (c) generating a number of echo signals, (d) changing the relative angular orientation of the array and the component around an axis and repeating steps (b) and (c), and (e) processing the echo signals to form at least one processed echo signal.Type: GrantFiled: September 16, 2002Date of Patent: September 14, 2004Assignee: General Electric CompanyInventors: Thomas James Batzinger, Wei Li, Robert Snee Gilmore, Edward James Nieters, William Thomas Hatfield, Richard Eugene Klaassen, James Norman Barshinger, Bruno Hans Haider, Carl Lawrence Chalek, Robert John McElligott, David Charles Franklin
