Patent GB-369690-A (GB)
Title: Improvements in the manufacture and production of fatty acid nitriles
Filed: 1931-01-14
Abstract: Saturated fatty acid nitriles are obtained by hydrogenation of unsaturated nitriles under mild conditions of working, using a copper catalyst.  The mild conditions, necessary to avoid the production of amines, may be secured by the use of a comparatively inactive catalyst, or of a catalyst the activity of which has been diminished by previous use for the production of amines, or by using a catalyst having a comparatively small surface. Alternatively the catalyst may be strongly loaded, or the hydrogen may be diluted with inert gas. The reaction may be carried out in the liquid or vapour phase, in the presence or absence of solvents or diluents, and at atmospheric or increased pressure.  Suitable temperatures are 50-200 DEG  C. for increased pressure and 100-400 DEG  C. at atmospheric pressure.  The catalyst may be prepared by the slow reduction of copper compounds or natural copper ores, and may be deposited on carriers.  Examples are given illustrating the conversion of acrylic nitrile to propionic nitrile, of crotonic to butyric nitrile, or oleic to stearic nitrile, and of fumaric to succinic nitrile.

Title: Improvements in electric riveter
IPC: B21J15/26
Filed: 1924-01-25
Abstract: 223,459. Walker, C. J. Jan. 25, 1924. Riveting.-Machines in which the working stroke is effected by an electric motor are provided with an auxiliary motor for returning the parts to their original position. The ram 17, in which the snap is carried, is feathered to slide in the frame 1. A screw 8 is secured to the ram 17 by a headed pin 23 and socket 20 to allow relative rotation but only slight axial movement, frictional surfaces f being provided on the ram and screw to prevent relative rotation when pressed together axially. The screw is engaged by a nut 9 integral with the rotor 2 of the main motor which is provided with a spring-pressed brake 29 which can be released by a solenoid 34. The screw can be driven in either direction by the auxiliary motor 26 controlled by forward and reversing switches 45, 44, Fig. 4. Switches 43 - - 46 controlling the supply of current from the mains 40, 41 are operated through relays by a drum 47 which in its normal position joins contacts 51, 52 and 53, 54 thereby closing switches 45, 46, 43, thus taking off the brake 29 and driving the motors 26, 2 in the same direction so that the screw and nut rotate together. If the drum is rotated, against the action of a spring 55, the contacts 53, 54 and 51, 52 are broken but sufficient current flows through a resistance 58 to hold the switches 43, 46, although it would not close them if open, and contacts 56, 57 are joined thereby closing the reverse switch 44. A reverse torque is thus put on the screw 8 and it travels to the left until a rivet is encountered. Then the clutch faces f grip and the screw is held against rotation and advances until the resistance brings the rotor 2 to rest, the rush of current through the main motor opening a switch 69 to stop current in the control circuit 59 and thus allow the switches 44, 43, 46 to open, causing the nut to be held by the brake 29. Directly the main current is cut off the switch 69 closes and when the operator considers the rivet cold enough he releases the drum 47 which returns to its original position thus taking off the brake, putting a forward torque on the screw 8 and afterwards, owing to a switch 62 in the circuit 61 for operating the switch 43 being closed by the same means as the switch 46, a forward torque is put on the nut 9. The release of the brake allows the nut to rotate in the reverse direction, owing to the backward pressure of the ram thus screwing it off the screw and releasing the clutch f. The auxiliary motor then, owing to its small inertia, rapidly rotates the screw and withdraws the ram before the nut reaches its maximum speed. The backward movement of the screw is limited by stop teeth 11 engaging corresponding teeth on a spring extension 12. To prevent excessive movement of the ram the control circuit 59 includes a switch 70 which is opened by a projection 72, Fig. 1, in the feather groove 15 of the ram. A switch 74 may be provided to close the circuit 59 even if the switch 70 is open and another 75 to render it inoperative at will. The thrust of the nut is taken by a roller bearing 6.
