  • Patent number: 11993547
    Abstract: An electrical termination unit or feedthrough which may be used for routing electrical conductors through a chamber wall, or otherwise across a barrier between isolated atmospheric conditions. The electrical termination unit may have aluminum as the interface material to the chamber interface and may utilize a ceramic insulator. The electrical termination unit may have the aluminum used as the interface brazed directly to a ceramic surface of the insulator. The aluminum that forms the chamber interface may be formed within a hollow ceramic tube in the same process step that brazes the aluminum to the ceramic tube with a hermetic joint. Machining subsequent to the brazing of the aluminum to the ceramic insulator may allow for achievement of the final form desired. A method for manufacturing such an electrical termination unit.

  • Patent number: 11992822
    Abstract: A bleaching clay product, a method of producing and a method of decolorizing an oil are disclosed. The bleaching clay product comprises attapulgite that has been thermally activated. The bleaching clay product may have a permeability in oil in the range of 0.04-3 darcy and may have a surface area of 45-140 m2/g. The method of producing such bleaching clay product may comprise thermally activating a material that includes attapulgite by heating the material at a temperature in the range of 300 to 900° C. The method of decolorizing may include contacting for a contact time an oil with the bleaching clay product that comprises attapulgite that has been thermally activated, and separating the bleaching clay product from the oil to recover a decolorized oil that has a lower red color than the oil had prior to the contacting.

    Abstract: A technology is described for multipoint tissue elastic property measurement. An example method (700) 700 includes generating a treatment map (710) of an anatomical region that shows focal points within the anatomical region to be exposed to Focused Ultrasound (FUS) pulses; acquiring a reference MR-ARFI image (720) of the anatomical region containing the focal points using the treatment map; acquiring an active MR-ARFI image (730) for each of the focal points in the anatomical region during exposure of the focal points to the FUS pulses using the treatment map; interleaving the reference MR-ARFI image and active MR-ARFI images (740) to create a combined image of the anatomical region and the focal points; and calculating a tissue displacement measurement (750) for the focal points exposed to the simultaneous and/or rapidly interleaved FUS pulses using the combined image of the anatomical region and the focal points exposed to the simultaneous FUS pulses.

  • Publication number: 20180321338
    Abstract: A catheter for use in magnetic resonance imaging includes a catheter shaft having a proximal end and a distal end. A flexible lumen is supported on the distal end of the shaft, and the flexible lumen is configured to be expanded and contracted using a fluid introduced via the proximal end of the catheter shaft. A magnetic resonance coil formed on the flexible lumen such that the magnetic resonance coil may expand and contract with the flexible lumen. The magnetic resonance coil is coupled to an external match and tune circuit via magnetic resonance imaging device. The balloon coil includes nested bazooka or sleeve baluns along the length of the cable to minimize common mode currents on the outer surface of the cable to prevent high current hot spots that cause heating of the cable.
