摘要： A computer (21) processes the time between ultrasonic echoes received at a transducer (19) indicative of the outer radius and wall thickness of a workpiece (10) by subtracting (69) the weighted average (80-90) wall thickness from the weighted average outer radius to generate an internal radius for a large number of points around a spiral slice of the workpiece. The internal radii and angles are converted (69) to x and y coordinates. The centroid (X, Y) of each slice of data indicating workpiece cavity internal radii is determined (71) as twice the summation of the x coordinates and twice the summation of the y coordinates of all of the datum points of the slice. The least squares fit (73) of the X coordinates of the centroids of all of the slices and the least squares fit (74) of the Y coordinates of the centroids of all of the slices are then used to determine the average axis of the cavity of the workpiece. The X and Y coordinates of the end points of the average axis of the cavity are then converted (75) to polar coordinates to permit offsetting the end points of the workpiece commensurate amounts, whereby further machining will cause the internal cavity of the workpiece to end up more nearly centrally located, on average.

摘要： An arrangement for detecting metallic particles carried by a fluid includes a metallic probe member which surrounds an elongated passage through which the fluid flows and which is constituted by a split tube having two marginal portions delimiting a gap which extends along said passage and completely separates the marginal portions from one another. Capacitors are arranged at the gap and alternating electric current is caused to flow in the probe member around the passage so that the probe member and the capacitors form a tank circuit having resonance characteristics that are influenced by any inclusion then present in the passage in a manner dependent on the electromagnetic properties of the inclusion. The character of any metallic particle then present in the passage is determined from variations in the alternating electric current that reflect the influence of such metallic particle on the resonance characteristics.

摘要： A dual channel peak detector having an automatic gain control (AGC) circuitaintains an internal replica of a gated input signal waveform at a constant peak level. An rf signal is input to a double balanced mixer to select that portion of the signal within the time interval of interest. A delay and gate generator circuit provides a variable delay from a sync input and generates a variable length gate which gates on the double balance mixer to pass the signal of interest to the remainder of the peak detector circuit. The gated signal is amplified and multiplied by a pseudo dc signal from the AGC circuit. The peak level of the resultant gated signal is detected. The detected peak level is sampled and input to the AGC circuit which computes the AGC circuit output voltage required to maintain a constant detected peak level amplitude. The AGC circuit output voltage is summed with the voltage from a second channel, and is also output as a dB value and a ratio between channels.

摘要： A device for use in determining the characteristics of particles dispersed in a medium is described. The device has a sample cell for holding a sample containing particles dispersed in a medium. A transducer is positioned to emit sound waves into the sample of the sample cell. A mirror surface is positioned for translational movement within the sample cell without changing the level of the sample in the cell, for movement without the use of dynamic o-ring seals, and is positioned to reflect sound waves emitted by the transducer.

摘要： An apparatus and method for quantitative nondestructive testing (NDT) of a wire wherein noncontacting ultrasonics is used. A transmitter-transducer coil is held in close proximity of a test wire or tube and high amplitude electrical current pulses are passed in the coil. A magnetic field perpendicular to the longitudinal axis of the wire is applied in the region. As a result of the electrical current pulses in the transducer coil, eddy currents are produced on the surface of the test wire. As a result of the magnetic field applied in the region, these eddy currents lead to Lorentz forces in the wire, which in turn generate corresponding torsional waves in the test wire. These waves speed down the wire and are received by a reciprocal transduction process, by means of a receiver-transducer. The velocity and attenuation measurements of the torsional waves along the axis of the test wire are made precisely and accurately via multiple-transducer setups. The data are interpreted in terms of the material conditions including mechanical defects or flaws in the test wire.

摘要： Medallion-like articles for jewelry, decorative ornamentation and product identification, instrument panel light lenses and methods and apparatus for manufacturing same are disclosed. A medallion-like article for decorative or identification is formed by applying an uncured radiation curable polymer to an indicia bearing surface in a quantity sufficient to form a convex upper surface by means of its surface tension and then irradiating the polymer to effect its cure. Use of a flexible substrate, such as a vinyl or polyester film, upon which embossed indicia was formed, provides a flexible medallion which may be adhesively bonded to a contoured, non-planar surface. Upward curling of the medallion during cure is prevented by supporting the medallion on a water cooled platen during irradiation. A flexible, transparent lamp lense having a convex frontal surface is also formed by the ultraviolet cured photopolymer which is adhesively bonded adjacent to the lamp to form its lense.
