Patent GB-707173-A (GB)
Title: An improved method for the dephenolation of aqueous salt solutions by distillation, in the course of a phenol recovery process
Filed: 1951-09-07
Abstract: In the recovery of phenol from aqueous sodium phenolate, carbon dioxide is passed through the aqueous mixture and it is then allowed to separate into two liquid layers, viz. a phenol-rich layer and a water-rich layer; the two liquid layers are submitted to fractional distillation in separate columns, and the vapours obtained by the fractionation of the phenol-rich layer are utilized, by indirect heat exchange, to supply part or all of the heat required at the sump of the column wherein the water-rich layer is being <PICT:0707173/III/1> fractionated.  The aqueous phenol obtained as distillate from the fractionation of the water-rich layer is preferably returned to the carbon dioxide treatment stage.  Aqueous sodium phenolate is supplied through pipe 1 to column 2.  The mixture flows from tray to tray down the column in countercurrent to CO2, which is introduced through pipe 3.  From a central tray 5, where the sodium phenolate has already been largely converted into soda and phenol, the soda solution is withdrawn through pipe 6 and introduced into decanter 7, but the phenol, which contains unconverted phenolate, continues down the column, so that the remainder of the phenolate may be converted into phenol and soda, which are collected in decanter 7.  Soda solution is withdrawn from decanter 7, and passed through pipe 11 to column 12, wherein the phenol is stripped out.  The phenol-free solution is withdrawn from column 12 through pipe 13.  The phenol obtained in decanter 7 is withdrawn, dehydrated with sulphuric acid, and then distilled in a separate column (not shown).  The phenol vapours from this latter column are introduced by pipe 15 into boiler 14, wherein they condense thereby supplying part of the heat required for the stripping of the soda solution.  The remainder of the heat required for column 12 is supplied by steamheated boiler 17.  The liquid phenol withdrawn from boiler 14 is returned to the phenol distillation column as reflux.  The phenol and water vapours from the head of column 12 are condensed, and the condensate is collected in container 20.  Part of the condensate is returned as reflux to column 12, and the remainder is passed through pipe 9 onto tray 8 in column 2.

Abstract: 741,901. Dashpots. ETABLISSEMENTS NEYRPIC. Aug. 5, 1953, No. 21666/53. Class 108 (3). A dash-pot comprises a passage or passages 49 (Fig. 4) connecting the cylinder spaces 42a, 42b on either side of a piston 41, a compressed air chamber 56 in fluid communication with the cylinder, and means for decreasing the crosssectional area of the passage or passages 49, such that the resistance to movement of the piston 41, is directly proportional to its displacement in the cylinder 42. As shown in Fig. 4, a metering rod 43 obturates a sharp-edged orifice 49 in a plate 46 secured to the piston 41. The orifice leads via ports 47 and 45 to the piston rod side of the piston. Liquid displaced by entry of the piston rod passes into. the chamber 56 to compress air which serves to return the piston to its original position. The chamber 56 has a pressure gauge 58 and a safety valve 59. In Fig. 6, the piston progressively cuts off sharpedged orifices 63. The deflection-load characteristic of the devices is linear and the ratio of final to initial load may be 2: 3. The invention is applicable to fendering ships.

Abstract: 1,106,744. Solution mining. CONTINENTAL OIL CO. 24 May, 1965 [10 June, 1964- No. 21921/65. Heading E1F. [Also in Division F4] An underground cavity for the storage of liquids is formed in a soluble subterranean layer by means of two boreholes into which a non-solvent is admitted under pressure to produce a fracture between the boreholes, and a solvent is then passed along the fracture to dissolve the layer and form the cavity. A symmetrical roof for the cavity is achieved by use of a non-solvent less dense than the solvent to form a "blanket" between high spots on the roof and the solvent to preclude further dissolution, the non-solvent being held in a reservoir at one bore hole at least and at a level corresponding to the desired roof height so that the non-solvent spreads out across the roof as the desired height is achieved. An arrangement for displacing stored liquid from the cavity using inert fluids both less and more dense than the liquid is described.

Abstract: 1287866 Reducing iron losses in stator cores GENERAL MOTORS CORP 19 April 1971 [9 March 1970] 22062/71 Headings B3A and B3Q In A.C. machine stator cores 10 comprising a stack of laminations 11 with winding slots formed between spaced teeth 14, iron losses are reduced by flexing the laminations about the ends of the teeth. The laminations are punched or stamped from sheet magnetic material and are secured in registry by welding, riveting or by keys. The assembly is then annealed. The stack of laminations is placed on a support member 20 with the tips of the teeth 14 resting on a ledge 21. A single turn electrical coil 25 is placed above the stack and a bank of condensers 40 is discharged through the coil by a switch 45 which connects contacts 49, 50. The current surge in the coil 25 induces a potential in at least the end lamination to flex the core about the teeth 14 within the elastic limit of the magnetic material. The switch normally connects contacts 47, 48 to charge the condensers 40. The coil 25 comprises a steel ring which is rigidly mounted and provided with a tube (31) for water cooling, Fig. 3 (not shown). The effect of the flexure is to produce slip-shear movement between adjacent laminations to interrupt or break any electrical circuit path, which may have been formed by burrs or oxides produced during manufacture.
