摘要： The present invention relates to a process for the hydrogenation of compounds comprising nitrile or nitro functional groups to amine, aminonitrile or aminonitro compounds. The invention provides a continuous process for the hydrogenation of compounds comprising nitrile or nitro functional groups to amine or aminonitrile compounds in the presence of a heterogeneous hydrogenation catalyst in divided form and of a basic compound. The reaction is employed in a stirred reactor comprising an external loop for circulating the reaction mixture, allowing one portion of the hydrogenated products to be separated without withdrawing the catalyst, by using tangential filtration. The process of the invention applies especially to the hydrogenation of adiponitrile to an aminocapronitrile/hexamethylenediamine mixture.

摘要： A self-stripping terminal for an electrical connector has a resilient fork formed of two prongs or limbs which extend towards each other, perpendicular to the longitudinal axis of the terminal. Defined between the ends of the prongs is an electrical conductor receiving slot formed with flat parallel walls and with a bevel configuration at the opening or mouth of the slot. The limbs are carried on resilient arms whereby the slot can resiliently open over a wide range of sizes to allow the terminal to accommodate a wide range of electrical conductor diameters and to be used repeatedly.The terminal may also include a second fork which is turned towards the first fork and which may be a semi-rigid fork or another resilient fork. In either case, the second fork has a groove for retaining the conductor, thereby to prevent radial disengagement thereof from the fork.The flat and bevel configuration is formed with walls that are parallel to the axis of the conductor received therein. This restrains cutting of the conductor core by sharp edges during insertion of the conductor and subsequent use of the terminal.
摘要翻译：用于电连接器的自剥离端子具有由垂直于端子的纵向轴线彼此延伸的两个叉状物或四肢形成的弹性叉。在插脚的端部之间限定了形成有平坦平行壁并且在狭槽的开口处或嘴部处具有斜面构造的电导体接收槽。肢体承载在弹性臂上，由此槽可以在宽范围的尺寸上弹性打开，以允许端子适应宽范围的电导体直径并重复使用。端子还可以包括朝向第一叉状物转动并且可以是半刚性叉或另一弹性叉的第二叉。在任一情况下，第二叉具有用于保持导体的凹槽，从而防止其从叉子的径向脱离。扁平和斜面构造形成有与其中容纳的导体的轴线平行的壁。这就限制了在导体插入期间尖锐边缘的导体芯的切割和随后的端子的使用。
