    摘要： A vehicle anti-theft system in the form of a mechanically interengagable electronic key and lock includes stored key and vehicle identifiers in both the key and in the lock. A random number is generated in the lock each time the vehicle ignition switch is closed and that random number is used to encode one of the identifiers for transmission to the key. The key uses the corresponding stored identifier to recover the random number. The other stored identifier is then encoded using the recovered random number and the encoded other identifier is returned to the lock. The lock uses the generated random number to recover the second identifier for comparison to its stored value. If the comparison fails, vehicle operation is prevented. The system may effect several trials, each using a new random number before refusing further attempts. The lock electronics is preferably disposed in the vehicle fuel tank and controls operation of the vehicle fuel pump.

    摘要： A filter device and technique are described which rely on absorption rather than adsorption for the removal of gas phase contaminants. A filter media is composed of a plurality of wicking fibers each of which comprising a strand with a hollow region impregnated with any of a variety of liquid phase absorbing systems made from the combination of a carrier liquid and soluble complexing/degrading agent or agents. Each strand has a slot which connects the interior hollow region with an external surface. Capillary forces act on the carrier liquid such that the external surface is substantially dry and no appreciable adsorption of contaminates occurs on the external surface which would restrict the flow of an air stream through the filter media even after an extended period of use. The wicking fibers may be connected to an external reservoir which can be used to supply fresh absorbing fluid to the filter media giving them a potentially inexhaustible capacity. The filter media may be made from any of a variety of fibers which can rapidly transport a liquid phase by the nature of either their geometry or their chemical composition. Geometries may include multilobal cross-sectional configurations, porous hollow fibers, porous or striated fibers or tightly bundled microfibers, all of which exhibit the property of wicking fluid from an external source.

    摘要翻译： 描述了依靠吸收而不是吸附去除气相污染物的过滤装置和技术。 过滤介质由多个芯吸纤维组成，每个芯吸纤维包含具有浸渍有由载体液体和可溶性络合/降解剂或试剂的组合制成的各种液相吸收体系中的任何一种的中空区域的链。 每根股线具有将内部中空区域与外部表面连接的槽。 毛细管力作用在载体液体上，使得外表面基本上是干燥的，并且在外表面上没有明显的污染物吸附，即使在长时间使用后也会限制空气流通过过滤介质的流动。 芯吸纤维可以连接到外部储存器，其可以用于向过滤介质提供新鲜的吸收流体，从而给它们潜在的不竭的能力。 过滤介质可以由各种纤维中的任何一种制成，这些纤维可以通过其几何形状或其化学组成的性质快速输送液相。 几何可以包括多叶横截面构造，多孔中空纤维，多孔或条纹纤维或紧密束缚的微纤维，所有这些都表现出来自外部源的芯吸液体的性质。
