| 20090146680 | SELF-GUIDING INSTRUMENT CARRIER FOR IN-SITU OPERATION IN A GENERATOR - Removal of the rotor of a large electrical machine is costly and time consuming, and in particular the outage time of a power plant, which is needed for the removal of a generator rotor, is very expensive and should be minimized. To avoid opening of the generator for inspection and maintenance instrument carriages can be used. A method allows the reliable guidance for an in-situ instrument carrier inside the annular gap of a generator and a corresponding instrument carrier. The method avoids the use of sensors and active control systems for the guidance of the instrument carrier. A passively self-guiding system and method takes advantage of the internal structure of a generator and uses the passive centering properties of magnets to guide the instrument carrier through the annular gap of a generator. | 06-11-2009 |
| 20090252194 | METHOD FOR PASSIVE DETERMINATION OF THE OPERATING TEMPERATURE IN A THERMALLY HIGHLY LOADED DEVICE, AND APPARATUS FOR CARRYING OUT THE METHOD - A method is provided for determination of an operating temperature in a thermally highly loaded device. Multiple individual passive measurement elements, having a measurable physical parameter depending on a constant temperature set during heat treatment, are provided. The parameter is set differently for each of the different measurement elements which are combined to form an array. In a first measurement, values of the physical parameter for the array are determined before the array is subjected to the operating temperature. The array is subjected to the operating temperature in the device and in a second measurement, values are determined for all the measurement elements in the array. First and second measurement values of the physical parameter for each of the measurement elements are compared and the temperature of the heat treatment of that measurement element whose value of the physical parameter has changed the least is taken as the measured temperature. | 10-08-2009 |
| 20090256584 | GAP INSPECTION APPARATUS - An apparatus for inspection of a gap between two surfaces, at least one of which is ferromagnetic, for example in a generator, includes a sensor platform ( | 10-15-2009 |
| 20100041322 | METHOD AND DEVICE FOR PIN REMOVAL IN A CONFINED SPACE - A method for drilling or cutting a pin surrounded by solid material includes the use of a water jet tool having a nozzle that is arranged at an angle with respect to a main body of the water jet tool. The water jet is directed over a portion of the surface of the pin, and removes that portion thereby fragmenting the pin. In order to minimise damage to the surrounding material, the portions removed touches the interface between the pin and the surrounding solid material at a minimal number of points and over a minimal extent of the interface. The method is applicable in particular to the removal of pins used in a press-fit for the securing of blades on a turbine rotor. The method facilitates “in situ” removal of pins within a confined space in a short time and at reduced cost. | 02-18-2010 |

| 20080289421 | BOILER TUBE INSPECTION PROBE WITH CENTERING MECHANISM AND METHOD OF OPERATING THE SAME - A centering apparatus for internal nondestructive testing of a tube to be inspected includes an elongated shaft member coupled to an inspection probe; a plurality of fingers, pivotally attached at a first end thereof to a mounting surface affixed to the shaft member, the plurality of fingers circumferentially surrounding the shaft member; and an expansion mechanism, disposed between the plurality of fingers and the shaft member, the expansion mechanism configured to selectively and outwardly extend a second end of the plurality of fingers with respect to a longitudinal axis of the shaft member, so as to bring the second end of the plurality of fingers into contact with an inner surface of the tube to be inspected, thereby centering the inspection probe within the tube. | 11-27-2008 |
| 20080308128 | AUTOMATED SYSTEM FOR WATERWALL CLEANING AND INSPECTION - An automated cleaning and inspection system includes movement components for moving the system along water-wall tubing disposed in a combustor, cleaning components for cleaning the water-wall and inspecting components for inspecting the water-wall; wherein the moving, cleaning and inspecting are coordinated for automated performance. A computer program product and a method are provided. | 12-18-2008 |
| 20090027736 | PORTABLE SCANNER DEVICE FOR METALLURGICAL, NONDESTRUCTIVE TESTING - A portable, self-contained scanner device for metallurgical, nondestructive testing is provided. The portable, self-contained scanner device includes a chassis having wheels extending beneath a lower surface thereof, a nondestructive testing probe detachably fixed to the chassis, and a computer processor device coupled to the chassis. The computer processor device includes applications executable by the computer processor device for performing the metallurgical, nondestructive testing on a test subject. The scanner device also includes a display device that displays images in response to the metallurgical, nondestructive testing. The chassis, computer processor device, and display device move along the test subject as a single unit. | 01-29-2009 |
