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.
