Title: Improved process for recovery of adipic acid precursors
IPC: C07C29/50
Filed: 1963-09-16
Abstract: <PICT:1013617/C2/1> In the manufacture of adipic acid by oxidizing cyclohexane with molecular oxygen in the liquid phase and further oxidizing the primary oxidation products so obtained, the primary oxidation products are mixed with water and then separated into an organic phase and an aqueous phase before they are further treated to produce a product suitable for further oxidation to adipic acid. The further oxidation is preferably effected in two stages with nitric acid.  As shown, cyclohexane is oxidized in a vessel 2 with air supplied through a pipe 3, and the oxidation products are treated with water fed through a pipe 4.  The mixture is separated in a decanter 6 into an organic layer and an aqueous layer, which pass to vessels 7, 8, respectively. The organic layer passes to a drystripper 10 from which unoxidized cyclohexane is passed back to the vessel 2 by pipe 13.  The distillation residue from the dry stripper 10 passes to a wet stripper 18 to which water is supplied from a concentrator 35 (see below), and the distillate from the wet stripper is separated in decanter 14 into cyclohexane, which is returned to the vessel 2, and an aqueous layer which is sent to waste, wholly or in part, through pipe 15.  The distillation residue from the wet stripper passes to the adipic acid precursor storage vessel 25 either directly or by way of a refiner 22 in which a final distillation is effected and from which the distillation products pass via a decanter 12 to the vessel 25. The aqueous portion of the cyclohexane oxidation product collected in the vessel 8 passes to a concentrator 35, the distillate from which is fed to the wet stripper 18 (see above). The residue from the concentrator 35 passes to a crystallizer 27, from which the crystals pass to a filter 30, the filter cake being transferred to the vessel 25.  Comparative experimental results are given. Specifications 1,013,618 and 1,013,619 are referred to.

Title: Improvements in and relating to track switching devices
IPC: B61L5/06
Filed: 1964-09-14
Abstract: 1,041,629. Track switch control. SAAB A.B. Sept. 14, 1964 [Sept. 13, 1963], No. 37479/64. Heading B7N. A track switch operating arrangement driven by an electric motor includes a spring coupling device between the motor and the switch rail whereby in each of its positions the switch rail is resiliently urged into contact with one or other fixed rails. The spring coupling includes a pair of units 13, 14, each of which includes an end wall 15 and a pair of tubes 16, 17, respectively, extending therefrom parallel to the centre axis of the coupling. The walls 15 are respectively connected to a nut 31 driven by a screw-threaded shaft 32 coupled to the motor and to a shaft 33 connected to the switch rail. External to the free surface of each wall 15 end supports 22, 23 are provided which are connected by springs (not shown) and the end supports and units are slidably carried on guide bars 25-28 attached at their ends to a motor mounting bracket 10 and an end wall 29 of the coupling housing. Control bars 38, 39, Fig. 3, including switch control members 40-43, are rigidly attached respectively to the drive nut 31 and to the switch rail connecting shaft 33. Assume the switch rail is in one extreme position whereby control member 43 has operated switch 47 to indicate the track switch position by energizing lamp 66 and control member 48 has operated switch 45 to cut off the motor supply. The track switch can be changed to its second position by operation of push-button 64 whereby via closed switch 44, contactor 60 is energized to connect a 3-phase supply to the motor in such a sequence that the motor rotates in an opposite direction to that which moved the track switch into its first position. The spring coupling is designed such that movement of the nut 31 is directly transmittedto the switch rail via coupling 33 until the rail reaches its second position which is indicated by control member 42 energizing lamp 65 by operating switch 46. However, control members 40, 41 are spaced further apart than members 42, 43, hence the nut 31 is driven a further distance until control member 40 opens the motor circuit by operating switch 44. This additional movement, depending on its direction, is taken up by compression or expansion if the spring coupling which then acts to resiliently maintain the switch rail in its new position. Means are provided for reversing the motor drive should the switch rail encounter an obstruction to its movement and for moving the rail to its opposite position when it is forceably moved, e.g. by a running vehicle, from a first position.
