    摘要： A system and method for assessing the quality of spot weld joints between pieces of metal includes an ultrasound transducer probing a spot weld joint. The ultrasound transducer transmits ultrasonic radiation into the spot weld joint, receives corresponding echoes, and transforms the echoes into electrical signals. An image reconstructor connected to the ultrasound transducer transforms the electrical signals into numerical data representing an ultrasound image. A neural network connected to the image reconstructor analyzes the numerical data and an output system presents information representing the quality of the spot weld joint. The system is trained to assess the quality of spot weld joints by scanning a spot weld joint with an ultrasound transducer to produce the data set representing the joint; then physically deconstructing the joint to assess the joint quality.

    摘要： A nozzle extension for use with a nozzle of a particulate spray machine features a first substantially linear section terminating in a curvilinearly angled output section having a passageway with a diameter larger than a passageway in the linear section. The larger volume of the output section induces peripheral turbulence in the particulate flow to minimize clogging of the output passageway.

    摘要： A portable gas dynamic cold spray gun eliminates many of the inherent limitations of the prior art by minimizing a scatter of operating parameters and improving its efficiency. According to one feature of the present invention, the powder flow rate is continuously measured so that the powder flow rate and/or the flow rate of the pressurized gas can be adjusted accordingly in order to control the deposition efficiency of the spray gun.

    摘要： A method and apparatus are provided for determining the preload in a dental implant system. The preload is determined by transmitting a sonic impulse, which is preferably an ultrasonic impulse, at a predetermined frequency to the head of the implant screw through a transducer, which may be incorporated into the head of the screw, the head of a wand which generates the sonic impulse, or the transducer and pulse-generating instrumentation may be incorporated into a torque generating instrument used to tighten the screw. The preload is determined by measuring the delay between the first and second reflections through the preloaded screw to determine a preload value and comparing that value with a pre-established baseline value for the screw, and comparing the difference with a predetermined table of values to determine the preload on the screw.

    摘要： The wetted surface of a pressure vessel, a structural internal or a weld is repaired by removing the contacting radioactive fluid, forming a powder mixture of metallic particles and ceramic particles and then spraying the powder mixture on the formerly wetted surface to form a protective cold sprayed coating thereon. As-deposited coatings having a surface smoothness of 125 RMS or better may be nondestructively examined by ultrasonic, eddy current or dye penetrant tests without a preliminary grinding step.
