摘要： A sliding blade damper is provided with an improved seal arrangement around the blade withdrawal aperture. Two pairs of flexible sealing strips are used, mounted on either side of the aperture and pressing against the opposite sides of the blade. The unattached edges of the sealing strips are curled and bent away from the blade. The curled edges of one pair of strips hook the curled edges of the other pair, so that when the blade is inserted into the damper, the spreading apart of the first pair of strips serves to partially spread apart the second pair as well. In this manner the leading edge of the blade penetrates between the second pair of strips rather easily, lessening the chances that those strips will be bent or torn.
摘要翻译：滑动叶片阻尼器设置有围绕叶片提取孔的改进的密封装置。使用两对柔性密封条，安装在孔的两侧并压靠在刀片的相对侧上。密封条的未附着的边缘被卷曲并且从叶片弯曲远离。一对条带的卷曲边缘钩住另一对的卷曲边缘，使得当叶片插入阻尼器时，第一对条带的扩张部分也用于部分地分开第二对。以这种方式，叶片的前缘相当容易地穿过第二对条带之间，减少了这些条带被弯曲或撕裂的机会。

摘要： Valuable metals, particularly vanadium, may be recovered from oil soot by firing crude oil to produce oil soot, collecting the soot, and recycling the collected soot for refiring until substantially all of the soot is converted to slag. The recycling of the collected soot is accomplished by the use of at least one air eductor to provide the motive power for pneumatically recycling the collected soot. During the recycling, the soot must be maintained at a temperature above its dew point, and wetting of the oil soot must be avoided.
摘要翻译：有价值的金属，特别是钒可以通过焙烧原油从油烟中回收，以产生油烟，收集烟灰，以及回收所收集的煤烟以进行再燃烧，直到基本上所有的烟灰转化为渣。收集的烟灰的再循环通过使用至少一个空气喷射器来提供用于气动回收所收集的烟灰的动力来实现。在回收期间，烟灰必须保持在高于其露点的温度，并且必须避免油烟的润湿。

摘要： There is disclosed an air lock filter system for separating solids from gases at temperatures up to about 1200.degree. F. wherein the filter element is a rigid porous refractory tube in an air vent for a pressure vessel. The filter element is located so that gas under pressure introduced into the vessel backwashes the filter element.
摘要翻译：公开了一种用于在高达约1200°F的温度下从气体中分离固体的气密过滤系统。其中过滤元件是用于压力容器的通风口中的刚性多孔耐火管。过滤元件被定位成使得在压力下被引入容器的气体反冲洗过滤元件。
