| 20130091951 | LOW PROFILE ULTRASOUND INSPECTION SCANNER - An inspection scanner is described that has a low profile construction designed to fit into tight spaces and inspect structures such as weld joints. Wheel frame assemblies carry a probe holder assembly with an ultrasonic (US) array that emits US beams through the structure and receives reflected sound waves. The probe holder assembly extends and US beam is angled away to inspect in tight locations. The wheel frame assemblies roll on wheels that drive an encoder. Encoder provides the specific locations for the received sound waves with respect to the weld. The locations and received sound waves are used to reconstruct a signal showing imperfections inside of structure. The wheels may be magnetic to hold it to the structure being inspected. A brake system may be employed to hold the inspection scanner at a given location. | 04-18-2013 |
| 20130239689 | ULTRASONIC ARRAY FOCUSSING APPARATUS AND METHOD - A method is provided in which radiussed components are scanned by moving the focal point of a curved array into the component, whilst keeping the geometric focal point of the array coincident with that of the radiussed component. | 09-19-2013 |
| 20130291640 | SYSTEM AND METHOD FOR INDUSTRIAL ULTRASONIC INSPECTION USING PHASED ARRAY PROBE AND DISTANCE-GAIN-SIZE FLAW SIZING - An industrial ultrasonic inspection system is capable of scanning for discontinuities in relatively thick solid objects such as solid core steel alloy turbine shafts. A phased array probe located on the turbine shaft periphery transmits ultrasonic pulses in a sector-shaped scanning field within the shaft that includes the inner 50% core volume that is of special interest in non-destructive evaluation and inspection. Staggered pulse firing alone or in combination with variable pulse repetition frequency (PRF) may be utilized in order to balance image quality with inspection speed. Discontinuities are identified by analysis of reflected echo waveform energy. Discontinuity size and position within the inspected object is correlated with an equivalent reflector size (ERS) by the Distance-Gain-Size (DGS) method. | 11-07-2013 |
