摘要： A safety hydraulic brake system for automotive vehicles which includes a control cylinder having an inlet connected to a hydraulic pressure source, and first and second outlets connected to brake cylinders at front and rear wheels, respectively. A valve is located at each outlet and normally allows pressurization of the front and rear wheel cylinders upon actuation of the hydraulic pressure source. First and second pistons, each having a by-pass valve, are slidable in the control cylinder. The pistons and by-pass valves are operable, when there is a loss of brake pressure in the lines to one set of brake cylinders, to effect closing of the control cylinder valve to that brake cylinder set. This allows brake pressure to be maintained at the other set of wheel cylinders and the vehicle to be safely braked. In addition, for heavy vehicles such as buses and trucks, an additional control cylinder device can be incorporated providing separate braking systems for each of the rear wheels so that loss of brake pressure to one rear wheel does not affect brake pressure at the other. Further, the system is designed to accomodate ready air bleeding from the brake lines.
摘要翻译： 一种用于汽车的安全液压制动系统，其包括具有连接到液压源的入口的控制缸，以及分别连接到前轮和后轮处的制动缸的第一和第二出口。 阀位于每个出口处，并且通常允许在驱动液压源时对前轮和后轮缸加压。 每个具有旁通阀的第一和第二活塞可在控制缸中滑动。 当制动压力在一组制动缸中失去制动压力时，活塞和旁通阀可操作，以使控制气缸阀关闭到该制动液压缸组。 这允许制动压力保持在另一组轮缸和车辆被安全地制动。 此外，对于诸如公共汽车和卡车的重型车辆，可以结合附加的控制缸装置，为每个后轮提供单独的制动系统，使得一个后轮的制动压力的损失不会影响另一个后轮的制动压力。 此外，该系统被设计成容纳来自制动管线的就绪空气渗出。

摘要： A process is described for recovering phenylcyclohexane as principal product from dicyclohexylbenzenes by heating the latter in the presence of at least an equal amount by weight of benzene and an acid clay or zeolite catalyst at a temperature of 190.degree. - 400.degree.C. The period of heating is preferably controlled so that no significant cracking of the phenylcyclohexane is caused. The process is a useful adjunct to the known methods of production of phenylcyclohexane by hydrodimerization by benzene. The latter process gives significant amounts of dicyclohexylbenzenes as by-product. The present process enables this generally undesirable by-product to be converted to phenylcyclohexane thus increasing the overall yield of phenylcyclohexane from benzene in the hydrodimerization process.
摘要翻译： 描述了一种通过在至少相当量的苯和酸性粘土或沸石催化剂存在下在190-400℃的温度下加热后者，从二环己基苯中回收苯基环己烷作为主要产物的方法。 优选控制加热，使得不会引起苯基环己烷的显着裂化。 该方法是通过苯的氢化二聚制备苯基环己烷的已知方法的有用辅助物。 后一种方法产生大量的二环己基苯作为副产物。 本方法使得这种普遍不希望的副产物转化为苯基环己烷，从而在加氢二聚过程中从苯增加了苯基环己烷的总产率。
