    • A pore-water profiler and method for sampling pore water. The pore-water profiler includes a sample intake probe that receives the fluid to be sampled. A clog-resistant first filter filters the fluid as it enters the sample intake probe. A second filter, which has a pore size less than the pore size of the first filter, filters the fluid a second time before the fluid enters a sample container. A sample triggering system connected to the sample container initiates sampling by causing the fluid to be drawn into the sample intake probe. The profiler provides high-resolution (centimeter-scale) vertical pore-water profiles. The sequential filtration of the pore water avoids the problem of sample-circuit clogging, even in sediments dominated by fine or organic-rich particles. The profiler has all non-metallic, acid-washable components that contact the fluid sample, making the profiler suitable for trace-inorganic studies.
    • 孔隙水分析仪和孔隙水取样方法。 孔隙水分析器包括接收要采样的流体的样品进样探针。 阻塞第一过滤器在进入样品进样探针时对流体进行过滤。 具有小于第一过滤器的孔径的孔径的第二过滤器在流体进入样品容器之前第二次对流体进行过滤。 连接到样品容器的样品触发系统通过使流体被吸入样品进样探针来开始采样。 轮廓仪提供高分辨率(厘米级)垂直孔隙水分布。 孔隙水的顺序过滤避免了样品回路堵塞的问题,即使在由细颗粒或富有机物颗粒主导的沉积物中也是如此。 轮廓仪具有接触流体样品的所有非金属,酸洗组分,使得轮廓仪适合于微量无机研究。

    • An apparatus for and a process of evaluating well bore flow of water and for sampling of water within a well. A hose is inserted into the well to a known depth. To evaluate the water, a tracer fluid is introduced into the hose until the pressure within the hose exceeds the hydrostatic pressure at the known depth by a preset amount. The tracer fluid is then rapidly released into the well. The tracer fluid is detected in water pumped from the well, and the elapsed time between release of the tracer fluid into the well and detection of the tracer fluid in the water pumped from the well is determined. The process is repeated at a second known depth, and the tracer fluid travel time between the two depths is determined. From this and the cross-sectional area of the well, the incremental volumetric well bore inflow to the well between the two depths is calculated. The process can be repeated at several depths within the well to permit construction of a velocity profile of water movement within the well. To obtain a water sample from the well, the hose is inserted to the desired depth, and an inert gas is introduced into the hose. The gas is then vented from the hose, and water from the well enters the hose to replace the vented gas. The hose is then withdrawn from the well, and gas is again introduced into the hose, causing the water sample to be discharged. Appropriate valves are provided to control the apparatus.
    • 评估井的井眼流量和井内水的取样的装置和过程。 将软管插入井中至已知的深度。 为了评估水,将示踪剂流体引入软管中,直到软管内的压力超过已知深度处的预定量的静水压力。 然后将示踪液快速释放到井中。 在从井中泵送的水中检测到示踪剂流体,并且确定示踪剂流体释放到井中之间的经过时间以及从井中泵送的水中的示踪剂流体的检测。 该过程在第二已知深度处重复,并且确定两个深度之间的示踪剂流体行进时间。 从该井和井的横截面积中,计算两个深度之间的井的增量体积井眼流入。 该过程可以在井内的若干深度重复,以允许在井内构造水运动的速度分布。 为了从井中获得水样,将软管插入所需的深度,并将惰性气体引入软管中。 然后将气体从软管排出,并且来自井的水进入软管以更换排气。 然后将软管从井中取出,并将气体再次引入软管中,导致水样品排出。 提供适当的阀门来控制装置。

    • A process for the synthesis of homogeneous advanced ceramics such as SiC+AlN, SiAlON, SiC+Al.sub.2 O.sub.3, and Si.sub.3 N.sub.4 +AlN from natural clays such as kaolin, halloysite and montmorillonite by an intercalation and heat treatment method. Included are the steps of refining clays, intercalating organic compounds into the layered structure of clays, drying the intercalated mixture, firing the treated atmospheres and grinding the loosely agglomerated structure. Advanced ceramics produced by this procedure have the advantages of homogeneity, cost effectiveness, simplicity of manufacture, ease of grind and a short process time. Advanced ceramics produced by this process can be used for refractory, wear part and structure ceramics.
