Title: Separation of cyclohexanone oxime and nitrocyclohexane from mixtures thereof
IPC: C07C/
Filed: 1962-03-16
Abstract: Cyclohexanone oxime is recovered from a mixture containing nitrocyclohexane and cyclohexanone oxime by contacting the mixture with an aqueous solution of not less than 1 mole of an alkali metal hydroxide having a concentration of from 5 to 30% for each mole of nitrocyclohexane to form a water-soluble salt of the nitrocyclohexane and to precipitate cyclohexanone oxime, and separating the cyclohexanone oxime from the water-soluble salt of nitrocyclohexane, e.g. by filtration. The nitrocyclohexane may be recovered from the remaining solution by neutralising the water-soluble salt to form an aqueous layer and an oil layer of nitrocyclohexane and separating the nitrocyclohexane oil layer from the aqueous layer, e.g. by decantation. In a modification of the process the aqueous solution of alkali metal hydroxide comprises the aqueous portion of a two-phase system, the other phase being a water-immiscible solvent for cyclohexanone oxime; in this process the precipitated cyclohexanone oxime dissolves in the water-immiscible phase and is recovered therefrom Suitable solvents include benzene, n-heptane, hexane, toluene, xylene and cyclohexane. Sodium hydroxide is the preferred alkali metal hydroxide.

In a heavy water moderated reactor, the fuel elements are separated from the water by a sheath and a concentric outer pressure tube. A liquid organic coolant flows inside the sheath and the fuel element. The annular zone between the sheath and pressure tube is occupied by both gas and coolant fluid. The gas is dissolved in the coolant and released under the thermal conditions existing in the zone between the pressure tube and sheath. In one embodiment, to facilitate the gas release in this zone, the sheath is provided with holes spaced regularly along its length. A flow of coolant from the interior of the sheath takes place and a mixture of gas and fluid is formed within the zone, the speed of flow of which is limited by internal restrictions. In a further embodiment, the annular zone has a separate supply of coolant saturated with an inert gas.

In the full-load position of the governor shown in Figs. 1 and 3, the cam g operates the lever r during the first part of the delivery stroke so that the suction or by-pass p is held open by the lever q. When the lever reaches the lower part of the cam g, the valve p closes and injection begins and continues until the end of the stroke, as the lever s is out of action during this period. In the no-load position of the rod y shown in Fig. 4, the lever r is out of action, injection takes place during the initial part of the stroke, and is cut off by the lever s opening the valve p. At any intermediate position of the rod y, the lever r opens the valve p for a variable period during the first part of the stroke and the lever s opens it for a variable period during the latter part of the stoke. The time and duration of injection may be adjusted also by means of the set screws u in the levers r, s. In another form, the levers r, s are operated by two cams on the shaft b, and the levers may be pivoted on the governor controlled eccentrics or on fixed fulcra the regulation being effected in the latter case by two governor controlled wedges between the levers r, s and the lever q.

Abstract: 968,420. Making beams; welding by fusion; straightening. PULLMAX A.B. March 22, 1962 [March 23, 1961], No. 11001/62. Headings B3A, B3E and B3R. In a machine for making beams consisting of web and flange plates fusion welded together, a flange-plate and a web plate are longitudinally fed through the machine under the guidance of rollers, and the joint between the web plate and the flange plate is welded at a position between two sets of rollers which press the flange plate against the web plate. Consumable electrode welding may be used. The welding may be carried out continuously while the plates are fed or intermittently during intervals when the plates are stationary. The web plate 1, Figs. 2 and 3, is fed between vertically adjustable rollers 4, 5, 6, 7 and the flange plates 2, 3 are supported on rollers 14, 15 and pressed against the web by driven rolls 16, 17 having inclined knurling which presses the flanges downwardly. Two complete sets of rolls are provided,the rolls 16, 17 being side-by-side and the rolls 4, 5, 6, 7 being staggered. The rolls serve to guide and straighten the plates 1, 2, 3. The rolls on one side of the beam are mounted on a fixed frame 20. The rolls on the other side of the machine are mounted on two slides 18 each of which is individually adjustable towards or away from the beam on guides on a frame 21 which is itself adjustable in the same direction. Welding is effected at a position between the inlet and outlet pairs of rolls 16, 17. In a modification, Figs. 4 and 5, for welding a T-beam, the flange plate 45 is supported on vertically adjustable rolls 71 and guided by rolls 68. The web plate 44 is pressed against the flange plate 45 by grooved rolls 54, 55 and is guided by adjustably mounted rolls 59, 60. The rolls 54, 55 are adjustable by rotation of threaded supporting columns 56 by a chain 58 driven by a motor 57. In order that after welding the beam shall be straight it is pro-stressed during welding by the upward pressure of a roller 89 mounted on a fluid pressure ram 52 and rotated by a motor to feed the beam through the machine.

Abstract: 1,024,454. Discharging from elevators. D. BEAUMONT. June 18, 1964 [March 21, 1963], No. 11230/63. Heading B8A. Conveying apparatus comprising an intermittently operated transfer means at the junction between the top of an elevator 10 and a horizontal slide conveyer 12. Trays 22 resting on angle supports 21 attached to a pair of endless elevator chains 13, 14 are pulled by the transfer means on to a pair of parallel angle members 23, 24 of the slide conveyer whereupon a tray already on the remote end of members 23, 24 is pushed on to a similar elevator 11. The transfer means comprises two spaced angle members 25, 26 supported for reciprocation on rollers 30. A loop structure 31 attached to the ends of members 25, 26 surrounds the slide conveyer members 23, 24 and has tray engaging transfer blades 34 mounted thereon by means of bars 32, 33. Levers 41 rigidly secured to a pair of rods 39, 40 which are each pivotally mounted to the members 25, 26 are pivoted upwardly to engage the trays on the slide conveyer during the transfer stroke of the transfer means, by means of a cross-link 42 connecting the front two levers 41, this link being moved transversely of the slide conveyer by a cam-actuated rod 43. The latter is connected to a spring- loaded member 44 incorporating a follower 45 to engage a cam 46. The shaft 55 which drives the cam 46 also drives an arm 56 having a roller 57 engaging a slot 28 in a cross-member 27 between the two angle members 25, 26. Rotation of the arm 56 causes the transfer means to reciprocate, but an arcuate section 29 of the slot 28 causes a dwell in the movement in the forward position. The drive of the transfer means and the elevation chain is synchronized such that the dwell of the transfer means coincides with a dwell in the elevation movement caused by a Geneva Stan wheel 67 in the driving system from a common motor. During the reciprocation of the transfer means, the cam-actuated rod 43 slides freely in an elongated slot in the cross-link 42. In a further embodiment, Fig. 6 (not shown), trays are passed up and down a pair of adjacent elevators before being passed to the elevator which feeds the slide conveyer.
