Title: Recovery of acrylonitrile
Inventor: BREAM JOHN BERNARD
Filed: 1959-06-03
Abstract: Hydrogen cyanide is removed from a dilute aqueous solution of acrylonitrile containing also an aliphatic aldehyde and hydrogen cyanide by, in a first stage, distilling the solution to take off an overhead fraction containing acrylonitrile, hydrogen cyanide, aldehyde and water, which is condensed and separated into an organic phase and an aqueous phase, then, in a second stage, vapourising the organic phase to take off a second overhead fraction containing acrylonitrile, hydrogen cyanide, aldehyde and water, and finally, in a third stage, feeding the latter fraction without condensation to a still operated continuously under such conditions that the hydrogen cyanide is removed as an overhead fraction and acrylonitrile is recovered in the base product.  The process is preferably used for the separation of hydrogen cyanide from acrylonitrile obtained by the reaction of propylene or acrolein with ammonia and molecular oxygen at elevated temperature in the presence of a catalyst, e.g. molybdic oxide.  The second and third stages may be effected in stills operated under reduced pressure.  The aqueous phase separated from the condensed overhead fraction of the first stage may be recycled to that stage.  The base product from the third stage may be separated into two phases and the lower aqueous phase recycled to the first stage. Distillation is preferably effected in the presence of conventional polymerisation inhibitors.

Filed: 1939-07-03
Abstract: 530,755. Fluid-pressure servomotor - control systems. COCKBURNS, Ltd., RODGER, J., and GRANT, T. July 3, 1939, No. 19271. [Class 135] A centrifugal emergency trip device for turbines and high-speed engines of the kind having a power-operated emergency valve controlled by a normally closed speed responsive control valve has this valve in the form of a hollow spring urged piston valve disposed eccentrically in a pocket in a rotor and adapted when a predetermined maximum speed of rotation is exceeded to open under centrifugal action and permit release of pressure fluid from a passage within the rotor. The rotor 1 is coupled by a flange 21 with the rotor of a turbine or other engine and is formed with a pocket 2 having the hollow piston valve 3 slidably mounted on a pin 5 formed on a detachable closure for one end of the pocket. A spring 4 arranged between an inturned flange 7 on the valve and an abutment 8 adjustably mounted on the pin 5 normally holds the valve in the position in which a land 12 closes a passage-way connecting chambers 11 and 14. The land 12 and a lower land are made a slack fit in the seating so that there is continuous leakage past the valve surfaces to prevent gumming. The rotor is housed in a chamber 18 connected by a flange 20 with the turbine casing and provided with a pipe connection 19 leading to the power cylinder of the emergency valve. This conduit is connected with the chamber 11 by an axial passage 10 in-the-rotor and ports in the seat 32 and valve member 33 of a second piston rotatably connected to the rotor. A slight axial movement of this valve opens the conduit 19 to close the emergency valve. The position of the seat 33 is axially adjusted by the angular adjustment of a stud 34 having an eccentric portion 35 engaging a slot 36 in the seat. The stud also has an eccentric portion 37 engaged by a member 38 presenting a scale 39 for co-operation with an indicating lever 29. This lever is pivoted at 30 to a stud 31 and engages a spring- loaded rod 22 passing through the passage 10 and provided with a detent adapted to snap under a shoulder 23 on the valve 3 when it has moved to its open position. A knob 28 is provided for releasing the catch when resetting the apparatus. The seat adjustment may be automatically synchronized with endwise adjustment of the turbine rotor by operatively connecting the stud 34 with the usual end-tightening gear of the turbine rotor.

Title: Improvements in or relating to electromagnetically wound clockwork mechanism
IPC: G04C1/06
Filed: 1928-07-04
Abstract: 322,482. Szente, A. July 4, 1928. Electric clocks; winding-apparatus, electric.- In apparatus for electromagnetically rewinding the springs of clockwork mechanism, contacts 53 for the winding circuit are operated, from a shaft 32 geared to the winding arbor, this shaft being screw-threaded and carrying a disc which is traversed along the thread to open and close the contacts according as the spring is being wound up or is running down. These contacts are additional to other contacts 25<1> actuated by the movement of the armature of the electromagnet 1, in which the usual pawl and ratchet drive is replaced by ball-clutch mechanism. The winding arbor 6, Fig. 5, has a gear 28 meshing with a wheel 29 which is loose on a shaft 32 and has pins 35 passing through holes in a grooved disc 34. The disc 34 is threaded to traverse a screw thread on shaft 32 rigid with a wheel 33 gearing with a wheel 31 on the spring barrel 30. The grooved disc 34 engages the forked end of a member 37 which is guided on a rod 38 and carries a blade 40 to coact with a bell-crank 45 pivoted at 44 and with a lever 49 pivoted at 48. 45 and 49 control the contacts 53, 54 in the winding circuit of the magnet shown in Fig. 1. Member 37 also carries a disc 42 which coacts with the lower, tail-end of lever 49. With the parts in the position of Fig. 5 the circuit is closed and the electromagnet rotates wheel 28, winding up the spring and traversing disc 34 to the left. As the blade 40 moves to the left a spring 50 moves the lever 49 so that its top end locks under the end of the bell crank 45 and maintains contacts 54, 53 closed. The continued motion flexes the blade 40 until the disc 42 meets the tail end of the lever 49 and removes it clockwise. The blade 40 thereupon moves bell-crank 45 clockwise to open contacts 53, 54, Fig. 6. As the mainspring runs down the parts 34, 37, 40 return to the right. First the disc 42 moves away and the spring 50 locks the upper end of lever 49 over the end of the bell-crank 45 maintaining the contacts open. Later the blade 40 meets the lever 49 to remove it, whereupon bell-crank 45 closes the contacts under the influence of a spring 46. The blade 40 coacts actually with adjustable screws 51, 52 on the members 49, 45. The armature 4 oscillates between the poles 2, 3 of the magnet 1 against a spring 4<a> and is limited in its off position by a cord or band 26. Pivoted at 16 to the armature is a ring member 7, Fig. 1, which coacts with a disc 9 rigid with winding arbor 6, this disc having a tapered slot 11 accommodating a spring-pressed ball 19 so that the clutch only drives in one direction. A similar device in which the inner disc is secured to the arbor 6 and the outer ring is fixed at 17 to the base plate is used to prevent retrograde movement of the winding shaft 6. 24 is an additional contact lever which is actuated, to close contact 25<1>, by adjustable stops 22, 23 on the armature 4.
