摘要： Calcium sulphate is added to desanded tailings derived from a hot water extraction process for recovering bitumen from oil sand. Enough calcium sulphate (100 to 200 ppm) is added to remove naphthenates and sulfonates from the aqueous phase. As a result, the settling rate of the fines in the tailings is accelerated.

摘要： A plug valve has an actuating stem which is non-integral with the valve plug. The actuating stem is axially movable with respect to the valve plug to compressingly and sealingly engage an external sealing member in response to fluid pressure. The plug wedges itself into sealing engagement in response to fluid pressure.

摘要： The present invention is based on the following:(1) that when tar sand is conditioned and diluted in the hot water extraction process, there are two classes of anionic surfactants (originating from carboxylate and sulfonate groups) present in the process water;(2) that each of these surfactants has the potential to dominantly influence the maximizing of primary froth production by the process;(3) that it is possible for a particular extraction circuit to determine the critical free surfactant concentration in the process water at which primary froth extraction is maximized for each of the two classes of surfactant;(4) and that it is possible to determine which of the two classes of surfactant will first (that is, at lowest NaOH addition) dominate the process when a particular tar sand feed is being processed.The present invention therefore involves:determining the critical free surfactant concentrations ("C.sub.cs.sup.O " and "C.sub.ss.sup.O ") for the circuit for each of the carboxylate and sulfonate classes of surfactants;monitoring the free surfactant concentrations ("C.sub.cs " and "C.sub.ss ") in the process water for an ore being processed;determining which of C.sub.cs.sup.O and C.sub.SS.sup.O occurs at a lower NaOH addition;and then adjusting NaOH addition to the extraction process to bring the first dominating surfactant concentration toward the critical concentration value.

摘要翻译： 本发明基于以下几点：（1）当焦油砂在热水提取过程中进行调理和稀释时，存在于工艺水中的两类阴离子表面活性剂（来自羧酸盐和磺酸盐基团）; （2）这些表面活性剂中的每一种都有可能主导地影响通过该方法使初级泡沫产生的最大化; （3）特定提取电路可以确定在两种类型的表面活性剂中的主要泡沫提取最大化的工艺水中的临界游离表面活性剂浓度; （4），并且可以确定当处理特定的焦油砂进料时，两种表面活性剂中的哪一种将首先（即在最低的NaOH添加）中占主导地位。 因此，本发明涉及：确定表面活性剂各羧酸盐和磺酸盐类的电路的临界游离表面活性剂浓度（“CcsO”和“CssO”）; 监测处理矿石的工艺用水中的游离表面活性剂浓度（“Ccs”和“Css”）; 确定CcsO和CSSO中的哪一个在较低的NaOH添加下发生; 然后调节NaOH添加到萃取过程中，使第一主要表面活性剂浓度达到临界浓度值。

摘要： A seal for a shaft in a structural body. The seal is configured to surround the shaft within said structural body. The seal has a flange making a gasket seal with the structural body. The seal has at least one portion distorted and stretched into a tapered configuration and into a tension-related sealing association with the shaft. The seal is made of a memory-retainable material. This memory urges the distorted and stretched tapered portion towards its original configuration, thereby enhancing the sealing association with the shaft.

摘要： A system for sampling material from a remote location which selectively collects a predetermined quantity of material in a valve disposed inside a container. This measured amount of material is transferred to a movable receiving carrier while the receiving carrier is in a sealed relationship with the valve to prevent leakage of the sample material outside the receiving carrier. The movable receiving carrier is transported via an elongated tubular structure to a location remote from the container.

摘要： A packing arrangement for sealing an area about a shaft in a structural body includes a plurality of V-shaped packing rings in stacked alignment. The packing rings are made from a memory retainable material and preformed into the V-shaped configuration with a forming die. After being preformed, the V-shaped packing rings are compressed beyond their preformed configuration and placed in a packing chamber. The memory characteristics of the packing ring material are such that the rings are urged toward their preformed V-shape to compensate for any dimensional instability of the rings during thermal cycling. The packing rings also have a very small stack height and provide an increased number of sealing surfaces within a predetermined sealing area.
