摘要： Fuels containing fixed-nitrogen chemical species are combusted in a multi-stage process. The process which converts substantially all of the fixed-nitrogen into molecular nitrogen (and thus avoids the formation of significant amounts of nitrogen oxides from the fixed-nitrogen) consists of four steps: (a) mixing said fuel with at least one first oxidizing agent in amounts such that the equivalence ratio of said fuel to said oxidizing agent is at least about 1.4; (b) partially combusting the mixture resulting from step (a) in at least one first stage at a first temperature of about 1850.degree. to about 2150.degree. K., with a residence time of at least 0.03 second; (c) mixing the combustion products resulting from step (b) with at least one second oxidizing agent in an amount such that the equivalence ratio of combustion products to the total amount of oxidizing agents in the mixture will be about 1.0 or less, such mixing taking place under conditions such that the temperature of the mixture will not exceed about 1800.degree. K.; and (d) completely combusting the mixture resulting from step (c) in at least one second stage at a second temperature of less than about 1800.degree. K.

摘要： The present invention provides a self-lubricating track roller and a method of making the self-lubricating track roller. First, an inner ring is provided having a radially outwardly facing surface. A parting agent is applied onto the radially outwardly facing surface. Next, a self-lubricating material is applied over the radially outwardly facing surface. Then, an outer ring is formed around the self-lubricating material such that a radially inwardly facing surface of the outer ring is bonded to the self-lubricating material. A resilient tire is bonded onto the radially outwardly facing surface of the outer ring. In the resulting track roller, the radially outwardly facing surface of the inner ring has a surface profile that corresponds to a mating surface profile of the the self-lubricating material that is bonded to the radially inwardly facing surface of the outer ring.

摘要： A system and method is provided for igniting a propellant with an electrically conductive chemically insensitive polymer. The polymer is an electrical resistance heater to heat the propellant to its ignition temperature. Preferably, the polymer is an organic polymer. Surfaces of the propellant can be coated with the polymer. In the alternative, the polymer can be applied to a hollow bore in the propellant to form a self-pressurizing charge. Advantageously, the present invention controls ignition and prevents unintended ignition of the propellant.

摘要： A tubular radiant furnace having multiple radiation shields is capable of producing very high working temperatures in an extremely clean environment. A cool-walled quartz muffle tube surrounded by high temperature electrical heaters in a high temperature cavity defines the work chamber. Concentric radiation shields around the tube and the heaters are supplemented by end shields at both ends to form the high temperature cavity. The shields reduce the radiative loss from the tube and create a uniform high temperature cavity without adding significant thermal inertia to the system. The low thermal inertia leads to a fast response time for the furnace to heat up or cool down. A workpiece located within the working chamber sees the radiant field with a view factor that approaches 100 percent (100%), and this helps make possible the attainment of very high and uniform temperatures. The effect is enhanced by the proximity of the workpiece to the center of the working chamber. The furnace is capable of producing temperatures above 1,800K, and it is believed capable of operating in ranges up to 3,300K. Furnaces of this type are useful in the production of semiconductors and other materials that require very clean and uniform high temperature conditions. They are also useful in the production of materials that require very rapid heat up or cool down conditions.
摘要翻译：具有多个辐射屏蔽的管状辐射炉能够在非常干净的环境中产生非常高的工作温度。在高温空腔中由高温电加热器包围的冷壁石英马弗管限定工作室。管周围的同心辐射屏蔽和加热器在两端由端盖补充以形成高温腔。屏蔽件减少了管的辐射损失，并创建了一个均匀的高温腔体，而不会给系统带来显着的热惯性。低热惯性导致炉子加热或冷却的快速响应时间。位于工作室内的工件看到辐射场的观察因子接近100％（100％），这有助于实现非常高和均匀的温度。通过将工件靠近工作室的中心来增强效果。该炉能够生产1800K以上的温度，据信能够在3300K的范围内工作。这种类型的炉子可用于生产需要非常干净和均匀的高温条件的半导体和其它材料。它们也可用于生产需要非常快速升温或冷却条件的材料。
