  • Publication number: 20130221255
    Abstract: A solenoid fluid control valve having a valve body containing a solenoid coil, a fluid channel, and a seat, each coaxially disposed about a central longitudinal axis of the body, and a one-piece armature of MRE material. The armature is disposed within the fluid channel and magnetically actuable to seal against the seat, with operation of the solenoid coil actuating the armature with respect to the seat to alter the closure state of a fluid port. Also, a fluid check valve having a first valve body part defining a seat, a fluid port, and a first portion of a fluid chamber, with the seat including a permanent magnet element disposed adjacent the fluid port proximate the fluid chamber. A one-piece armature of MRE material is disposed across the fluid port and magnetically sealable against the magnet element. The armature and magnet element are configured to create a preselected magnetization offset pressure portion of a valve cracking pressure.

  • Patent number: 7889322
    Abstract: A specimen inspection stage implemented with a processing stage coupling mechanism provides a capability to conduct with maximum efficiency post-processing specimen inspections on-board a processing platform. Heavy inspection equipment is mounted on a specimen inspection stage that is separate from a processing stage. In a preferred embodiment, the processing stage moves in response to an applied motive force and performs laser-based processing operations on a specimen. While laser processing is ongoing, the specimen inspection stage remains parked in its home position. When it is time for post-processing inspection, a stage coupling and decoupling mechanism couples together the specimen inspection stage and the processing stage, which transports the specimen inspection stage to and from the specimen position.

  • Patent number: 7666381
    Abstract: High-power inductively coupled plasma technology is used for thermal cracking and vaporization of continuously fed carbonaceous materials into elemental carbon, for reaction with separate and continuously fed metal catalysts inside a gas-phase high-temperature reactor system operating at or slightly below atmospheric pressures. In one particularly preferred embodiment, in-flight growth of carbon nanomaterials is initiated, continued, and controlled at high flow rates, enabling continuous collection and product removal via gas/solid filtration and separation methods, and/or liquid spray filtration and solid collection methods suitable for producing industrial-scale production quantities. In another embodiment, the reaction chamber and/or filtration/separation media include non-catalytic or catalytic metals to simultaneously or separately induce on-substrate synthesis and growth of carbon nanomaterials.

  • Publication number: 20080041829
    Abstract: Inductively coupled plasma (ICP) reforming converts carbonaceous compounds into a fuel for use in generating electrical power. Energy rich hydrocarbon fuels, such as coal, marine diesel, oils, and hydrocarbon wastes are employed as a feedstock for the ICP, which transforms the feedstock into a fuel that can be used by fuel cells and gas turbines for the production of electricity. The overall efficiency of an ICP-based electrical power system can be increased by providing partial oxidation within the reaction vessel. The partial oxidation conditions consume a small amount of the reformed fuel gas, thereby liberating sufficient thermal energy to reduce the electrical power requirements of the ICP to maintain desired reactor temperatures, and providing an increase in the overall net electrical power production. The integrated power production system can also adjust to meet an increased requirement for process heat and steam by balancing the effect of partial oxidation.
