Chemical components in a mixture are analysed using scattering data representing the results of a diffraction experiment performed on the mixture. Using non-negative matrix factorisation or another optimisation technique, the scattering data is deconvolved into non-negative basis components that represent contributions to the scattering data from each chemical component and fitting coefficients are derived in respect of the basis components that represent the proportions of chemical components in the mixture.

An x-ray inspection apparatus may comprise an x-ray source, an x-ray detector, and a drive assembly. The drive assembly may be configured to lift a part carrier such that the part carrier is disengaged from a feed assembly and an object mounted on the part carrier is positioned between the x-ray source and the x-ray detector. The feed assembly may be configured to feed part carriers into and out of the x-ray inspection apparatus. The drive assembly may be further configured to subsequently lower the part carrier such that the part carrier is reengaged with the feed assembly.

The present invention relates to an apparatus and a method for inspecting battery cells for automation of total inspection. To this end, the present invention is configured such that test objects are sequentially stacked on a test object casing provided on an upper portion of a mounting stage of a main stage, images of the test objects are obtained by radiography after the test object casing is moved to a test object inspection unit, and the test objects stacked on the test object casing are unloaded to the outside after the images are obtained. Accordingly, the present invention enables total inspection to be performed on battery cells, which are the test objects, in order to quickly divide good and defective products, and solves a delay of a flow rate caused by X-ray inspection of the test object inspection unit in order to improve productivity and efficiency.

An apparatus and method are described which enable real time measurements to measure the margin to criticality in a process for manufacturing fissile materials. An exemplary apparatus includes a neutron source capable of being modulated, an optional moderator to reduce the thermal energy of neutrons from the neutron source, a collimator for controlling the direction of any neutrons emanating in use from the target, a plurality of detector arrays positioned in predetermined locations relative to a process vessel for detecting process variables and for sending signals representative of the process variables in real time to a processor for receiving the signals and converting the detected process variables into margin to criticality measurements.

A method of inspecting a foreign body in a film includes a first detecting process that detects a foreign body on a film with an optical imaging unit and obtaining foreign body information including at least positional plane coordinates information A on the film; a process of winding up the film on a core as the film roll after the first detecting process; a converting process of converting a position of the foreign body on the positional plane coordinates information A into positional information on positional space coordinates information B in the wound film roll; and a second detecting process of using a radiation imaging unit to the film roll, focusing the radiation imaging unit to adjust imaging focus on a targeted foreign body based on the positional space coordinates information B for the foreign body, and emitting radiation to detect and characterize the targeted foreign body.

A non-woven fiber article for use in a food, medical, or pharmaceutical production environment including a melt-spun polymer fiber is provided having a cross-section and a length and a detectable particulate present in an amount of 20 to 80 weight percent loadings of metal or 10 to 80 weight percent loadings of radiopaque particles to render the polymer fiber detectable by magnetic or X-ray detection, alone or in combination with a secondary functional particulate distributed with the polymer fiber to render the polymer fiber chemically responsive to a chemical reactant, change in pH or temperature. The detectable particulate and the secondary functional particulate are each independently present in a core, a sheath, or both portions of polymer matrix. A process of detecting a fabric made from such a fiber. The fabric article passes through detector. A signal is collected from the detector indicative of the presence of the fabric article.

There is provided an acquiring method of a projection image of a sample whose shape is uneven with respect to a rotation center, the method comprising the steps of setting the sample S0 at a position of the rotation center C0 provided between an X-ray source 116a and a detector 117, and acquiring the projection image of the sample S0 at each different rotation angle for each different magnification ratio over a rotation angle of 180 or more by rotating the sample S0 around the rotation center C0, and by relatively changing a separation distance between the X-ray source and the rotation center, or a separation distance between the rotation center and the detector in an optical axis direction according to the shape of the sample S0 and the rotation angle of the sample S0.

An x-ray inspection apparatus may comprise an x-ray source, an x-ray detector, and a drive assembly. The drive assembly may be configured to lift a part carrier such that the part carrier is disengaged from a feed assembly and an object mounted on the part carrier is positioned between the x-ray source and the x-ray detector. The feed assembly may be configured to feed part carriers into and out of the x-ray inspection apparatus. The drive assembly may be further configured to subsequently lower the part carrier such that the part carrier is reengaged with the feed assembly.

Various methods and systems are provided for analyzing sample inclusions. As one example, a correction factor may be generated based on inclusion properties of a first sample determined using both an optical emission spectrometry (OES) system and a charged-particle microscopy with energy dispersive X-ray spectroscopy (CPM/EDX) system. The OES system may be calibrated with the correction factor. The inclusion properties of a second, different, sample may be determined using the calibrated OES system.

An X-ray inspection device performs inspection by irradiating an X-ray on an inspection object conveyed in an X-ray shielded space. The device has a shielding gate, having a passage part the shape of which is changeable in correspondence with the outer shape of the inspection object, so as to pass the inspection object. The shielding gate may be retractably provided in a shielding position inside the shielded space.
