  • Patent number: 5253276
    Abstract: A method of ultrasonic inspection of a reactor nozzle involves positioning emitter and receiver transducers on the exterior vessel wall near the nozzle. The emitter transducer is positioned and oriented so that it generates both primary longitudinal and transverse beams. The primary longitudinal beam is directed at the inner radius of the nozzle. The transverse beam is directed toward the interior vessel wall at an angle of about 30.degree. to the normal. Most of the energy of the transverse beam is converted to a secondary longitudinal beam also directed toward the inner radius of the nozzle. The receiver transducer is positioned on the exterior vessel wall about 4" from the emitter transducer so as to be able to detect reflections of both the primary and second longitudinal beams from any potential defect in the nozzle volume adjacent the inner radius.

  • Patent number: 5193226
    Abstract: The present invention is for a face mask/earplugs case designed for on-site use by construction workers. Both face masks and earplugs are needed on an intermittent basis by construction workers when on site. The face mask/earplugs case of the present invention is attachable to a piece of clothing, thereby providing accessible storage of the face masks and earplugs when not needed. In one preferred embodiment, the case attaches to a helmet and is configured to substantially conform to the footprint of the helmet, thereby not obstructing or limiting the mobility of the wearer.
