摘要： An enhanced EMAT probe and coil construction takes advantage of heat transfer and magnetic flux principles to permit inspection of workpieces at elevated temperatures of 1200.degree. F. and higher. A ferromagnetic, cup-shaped probe assembly having an end cap and a barrel is provided for carrying a coil assembly, preferably one or more permanent magnets, and a frustoconical focus core. The magnets are located within the barrel and connected to the end cap, and the cup-shaped probe assembly positions the coil assembly proximate the surface of the workpiece. A plurality of passageways may be provided in the end cap and barrel for admitting cooling air to an interior portion of the cup-shaped probe assembly. The cup-shaped probe assembly serves to provide a return path for magnetic flux of the magnetic field back to the permanent magnet means. The coil assembly has a coil disk having a matrix of holes and grooves which allow at least one eddy current coil wire to be threaded and interwoven into the coil disk without shorting against itself. A layer of fiberglass cloth covers the coil assembly to thermally and electronically insulate it from the workpiece, providing a durable, rugged and economical construction.

摘要： A sensor system for mapping absolute acoustic noise intensity in a three-dimensional acoustic noise field. Localized noise sources within a vessel are extracted using a distant array of transducers mounted on the vessel wall. The absolute intensity can be measured even when totally masked by background noise at the transducer locations. The system includes an integrated transducer installation. Each transducer is an accelerometer which is mounted on the vessel wall using a rigid attachment rod which serves as an ultrasonic waveguide. The output of each transducer is split into low- and high-frequency components, the low-frequency component being a function of the vibrational displacement of the localized portion of the vessel wall and the high-frequency component being a function of the vibrational/ultrasonic waves propagating through the localized portion of the vessel wall.

摘要： Method and apparatus for the nondestructive testing of rock samples as a function of time are disclosed. A rock sample is placed in a sample vessel which simulates in-situ wellbore conditions of pressure, temperature and fluid effects. Ultrasonic signals are transmitted through the sample and the transit time is measured. The measurements are repetitively performed and the time history of the development of strength is recorded in order to determine when the rock sample begins to weaken.

摘要： An apparatus and method for measuring particle agglomeration or dispersion in fluid mixtures, such as polymer melts, resides in a piezoelectric transducer, a spherical fused quartz lens, and a fluid housing. A repetitive, broadband, ultrasonic wave is produced by the transducer and is sent into the lens, which also serves to isolate the transducer from the mixture. The ultrasonic wave meets a spherical dimple at the end of the lens which focuses a portion of it into a diffraction limited spot or "interrogation zone". Since the intensity of the wave is large in the interrogation zone, small changes in the impedance of the fluid in this zone, caused by passing agglomerates, will cause large fluctuations in the intensity of the back scattered wave, which is monitored by the transducer between pulses and displayed by associated electronic elements.

摘要： A method and an apparatus for transmitting and receiving electromagnetic ultra-sound, especially in non-destructive testing of electrically conductive material, comprising the steps of generating one or more magnetic fields by means of one or more electromagnets (1,2,3,4) and supplying a transmitter coil (8) in said magnetic field with a supersonic frequency, and scanning a receiver coil (56) in said magnetic field. In known apparatuses, especially in the testing of non-magnetic material, the signal/noise ratio of a received signal is unfavorable.According to the present invention said ratio is improved in that said magnetic field is generated during a short time compared with the time between two successively occurring magnetic fields, and that a number of pulses of well-defined length of supersonic frequency are supplied to the transmitter coil (8) when the magnetic field or fields have a sufficient strength.The receiver coil (56) is scanned after each such pulse, and the different receiver signals are summed up in an integrator (60). The said pulses each have a preferred length of a complete sinusoidally-shaped cycle, whereafter the respective pulse is extinguished entirely.
