Patent GB-716092-A (GB)
Title: Process and apparatus for producing hydroxy aromatics
Filed: 1952-11-13
Abstract: In the production of polyhydroxy aromatic compounds by fusing an alkali metal salt of an aromatic sulphonic acid with an alkali metal hydroxide in such proportions that the reaction mass passes through a viscous doughy stage, the process is characterized by subjecting the reactants to simultaneous positive kneading and cutting forces, or to simultaneous positive kneading, cutting, tearing, stretching and folding forces, during the reaction.  The reaction is carried out in a multiple-arm dough mixer, two of whose arms rotate on two different horizontal axes and are driven p  by a means capable of relatively high power output.  By a positive force is meant that it must be applied by a positively driven roll or blade.  Suitable mixers are kneader mixers, ribbon or screw conveyors and mixers, pug mills, mixing rolls and plasticators and banbury mixers.  The invention is illustrated by the preparation of resorcinol from disodium benzene meta-disulphonate and sodium hydroxide but reference is also made to ortho-sulphonates and trisulphonates, which may be substituted by groups such as amino or hydroxy groups.  The reaction and the discharge of the product are preferably effected in an inert atmosphere.  The temperature may be 300 DEG  C. to 400 DEG  C., and the pressure may be at or below atmospheric.  A slight excess of caustic soda produces a yield approaching 100 per cent.

Abstract: 658,746. Control of A.C. motors. IGRANIC ELECTRIC CO., Ltd. Nov. 6, 1947, No. 29606. Convention date, Nov. 6, 1946. [Class 38(iii)] To obtain a distinctive speed-torque characteristic from a polyphase motor its stator terminals T1, T2, T3 are connected to a single-phase source (two of the threephase lines L1, L2, L3) so that each of two-phase windings are in series with the third and a capacitor C1 is in series with one of the first two. The first step in controlling such a motor operating upon an overhauling load is shown in Fig. 2 whereby a characteristic as shown at 1L in Fig. 7 is obtained. After a transition stage, in which the condenser is discharged by a resistance connected in parallel, the second step, shown in Fig. 4, is reached, giving a torque-speed relation 2L. Succeeding steps for higher lowering speeds are shown in Figs. 5 and 6 (the last with three-phase excitation) and the corresponding characteristics at 3L, 4L, Fig. 7. All these connections are made while the rotor circuit contains high resistance, and in a final control connection further resistance is inserted to produce the characteristic 5L. The motor may have an electromechanical brake (not shown) with its winding connected across two of the primary leads.
