    摘要： A filtering element includes a circumferentially extending filter media having a pair of opposite ends. An end cap assembly closes the ends of the filtering media and consists of an annular cup-shaped member defining a circumferentially extending trough. A circumferentially extending band of sealant is dispensed into the trough. The media and the centertube, which supports the inner diameter of the media, is installed in the sealant within the trough. The sealant may be either Plastisol or a photo-initiating polymer. The end cap can be made transparent to ultraviolet light, so that the photo-initiated polymer can be cured by transmitting ultraviolet light through the end cap.

    摘要： Organic sulfur is removed from coal by extraction with a water/methanol/carbon dioxide mixture under supercritical conditions of temperature and pressure, i.e., at a temperature and pressure of the critical temperature and pressure, respectively. The preferred solvent used for extraction has the following composition (expressed as a mole fraction);______________________________________ Carbon Dioxide from 0 to 0.30 Methanol from 0.20 to 0.70 Water from 0.20 to 0.70 ______________________________________ Preferably, the mole fraction carbon dioxide is at least 0.05 and mole fraction of water is not greater than 0.65. Either fixed bed (semi-batch) or mixed reactor systems can be used. Operations may be carried out in a single stage using a solvent of constant composition, or it may be carried out in plural stages in which the critical temperature of the solvent used in each stage (except the first) is higher than that of the solvent used in the preceding stage. Overall molar quantities of solvent used in plural stage operations are in accordance with the mole fractions given above. A substantial amount of the total organic sulfur present is removed.

    摘要翻译： 在超临界温度和压力条件下，即在临界温度和压力的温度和压力下，分别用水/甲醇/二氧化碳混合物萃取，从煤中除去有机硫。 用于萃取的优选溶剂具有以下组成（以摩尔分数表示）; 0〜0.30的二氧化碳 - 0.20〜0.70的乙醇 - 0.20〜0.70的水分 - 优选地，摩尔分数二氧化碳至少为0.05，水的摩尔分数不大于0.65。 可以使用固定床（半批）或混合反应器系统。 操作可以使用恒定组成的溶剂在单个阶段中进行，或者可以在多个阶段中进行，其中每个阶段（第一个除外）中使用的溶剂的临界温度高于所用溶剂的临界温度 在前一阶段。 在多级操作中使用的溶剂的总摩尔数与上述摩尔分数相一致。 大量的存在的总有机硫被去除。

    摘要： A friction material matrix is described, containing a tin oxide, such as but not limited to stannous oxide or stannic oxide, and a binder system, the binder system physically or chemically binding the tin oxide. The tin oxide is preferably present in an amount in the range of about 0.3 to about 20 weight percent, based on the total weight of the friction material matrix. The tin oxide preferably has a Mohs hardness level of about 6.5. The tin oxide improves the performance behavior of a friction couple at an interface between the friction material matrix and an automotive braking element.
