    摘要： A system for determining the magnetic permeability of a material is provided. Two electrical inductors formed as primary and secondary concentric coils share a common magnetic core space. An AC voltage applied to the primary coil creates a magnetic flux in the core proportional to the magnetic permeability of a sample of the material positioned within the core space. The magnetic flux induces an AC voltage in the secondary coil indicative of the sample magnetic permeability. When the material is a magnetorheological fluid, the magnetic permeability is proportional to the concentration of magnetic particles in the sample and can be back-calculated from the amplitude of the secondary voltage signal. Sensitivity and resolution can be increased by using two identical sets of coils wherein a reference material forms a core for the primary set and the MR fluid sample forms a core for the secondary set.

    摘要： A coating applied to at least a portion of the surfaces of reactors, reactor internals, other reactor components, and/or heater tubes is provided in order to minimize the formation of metal catalyzed coke in hydrocarbon conversion processes operating at temperatures at about 350° C. (662° F.) or greater and in reducing environments. These coatings may comprise Nickel coatings or complexes thereof, such as Ni—Al, Ni—Cr/Cr carbide, as well as aluminum painted coatings that are applied in a reduction cure process (e.g., application temperatures of about 600° C. (1112° F.)). Additionally, where H2S is necessary for the process, such as to minimize thermal cracking, the coatings also reduce corrosion of base metal due to sulfidation attack and eliminate the requirement of continuous replacement of reactor internals and other components.

    摘要： Fuel supports for a nuclear reactor and methods of modifying fluid flow in a reactor using a fuel support. The fuel supports include a plurality of lumens and a plurality of fuel support apertures with each fuel support aperture being dimensioned for receiving a lower tie plate of a fuel assembly. Each lumen is fluidly coupled to a different fuel support aperture. At least one lumen is configured for attenuating a fluid flow differently than the fluid flow in at least one other of the lumen.

    摘要： Embodiments relate to a substrate or wafer edge support having an emmisivity greater than that of a silicon wafer, where the edge support is for supporting a wafer during processing to form circuit devices on or in the wafer. Embodiments also include temperature sensors, heat conducting gas jets, and photonic energy can be directed to sense and control the temperature of the edge support and/or wafer edge during annealing to reduce temperature roll-off or roll-up at the edge as compared to the center of the wafer. Specifically, use of an edge support having an emmisivity greater than or equal to that of the wafer during processing allows helium gas jets directed at the edge support and/or wafer edge to reduce temperature roll-up at the edge during annealing. Because wafers from different processes and anneal locations may all have different emmisivities, use of the feedback loop will enable one edge ring to support the uniform anneal of wafers with a range of different emmisivities.

    摘要： Apparatus for inducing electrically charged alignment changes in biological tissue includes a generally flat translucent cavity containing a volume of gas that includes water vapor, carbon dioxide and other similarly common molecules that is charged along one surface by a sequence of pulses of electrical charge each of a potential sufficient to excite the common molecules to a higher state. The opposite side of the cavity is then conformed for intimate contact with the skin of a person, thus communicating the electromagnetic pulses associated with each excitation level change into the tissue.
