摘要： The present invention relates to a sensor for and a method of detecting carbon monoxide in gas streams containing hydrogen. The sensor acts as a fuel cell and is comprised of a centrally placed membrane electrode assembly upon each side of which is positioned a current collector which has gas inlets that allow gas to flow to the membrane electrode assembly. Plates are positioned on each of the exterior surfaces of the current collectors such that when assembled, one side of the CO sensor forms an anode and the other side forms a cathode. At a constant voltage, a sample gas passes through the sensor such that low levels of Platinum on the sensor facilitate the detection of carbon monoxide. A reader attached to the sensor interprets the concentration of carbon monoxide and air is passed through the sensor for recalibration as needed.

摘要： A diesel particulate filter including a microwave-absorbing target housed within a waveguide cavity lined along the walls with a hard-electromagnetic surface (HES). The HES modifies specific electromagnetic boundary conditions for a given design frequency so as to enable the establishment of electromagnetic field patterns which are more uniform across the cavity thereby causing the target material to undergo enhanced uniformity heating. The heating of the microwave absorbing media causes particulate buildup to be vaporized and removed from the filter by the exhaust stream flow.

摘要： Rough machining of a glass-ceramic material article such as a radome is accomplished using a high-power Nd:YAG laser. The radome is rotated about its longitudinal axis, and the point of application of the laser beam is translated generally parallel to the longitudinal axis over either the inside or outside surface of the radome. The Nd:YAG laser preferably operates in a pulsed wave mode with a pulse duration of from about 0.3 to about 3 milliseconds, a pulse frequency of from about 50 to about 500 pulses per second, and a pulse intensity of at least about 3.times.10.sup.4 Watts per square centimeter. After laser rough machining, at least about 0.002 inches of material is removed from the rough-machined surface by a finish machining, preferably mechanical grinding.

摘要： A surface-protected composite article, such as a missile component, is prepared with a heat-sink substrate, a first composite layer of an pre-ceramic-matrix structural composite material, and a second composite layer of a reinforced silicone pre-ceramic material. The silicone material is co-curable with the organic matrix of the first composite layer. The silicone at the surface of the article is thereafter converted to a silica refractory by an appropriate treatment such as exposure to an oxygen-rich plasma or a high-surface temperature. The silica protects the surface of the composite material.
