Title: Production of acetic acid
Inventor: THOMAS EDWARD BOADEN
IPC: C07C51/12
Filed: 1950-09-18
Abstract: In the synthesis of acetic acid from carbon monoxide and methanol in the vapour phase in presence of active carbon impregnated with nickel iodide, the carbon monoxide is passed through successive zones of active carbon, the iodine content of the catalyst is maintained by a suitable supply to the reactor, the direction of flow of the reactants is periodically reversed, the methanol supply by-passes the first active carbon zone in the direction of flow obtaining, and the last such zone is maintained at a temperature above that at which acetic acid condenses but below reaction temperature so that it absorbs nickel from the outgoing vapours without condensation of acetic acid, and upon reversal of flow, yields nickel to the incoming gas.  Iodine may be supplied as methyl iodide, and water or methyl acetate may be introduced to the reactor.  The active carbon zones may be separated by mixing zones containing inert packing material, through which the methanol may be introduced.  Liquid methanol supply or cooled recycled reaction mixture may be used for cooling.  Where there are a number of mixing zones, methanol may be at first supplied only to the earlier ones in the direction of flow, then supplied to progressively later ones, until the last, when the direction of flow of the carbon monoxide is reversed.  An example is given. Specification 692,145 is referred to.

Title: Metal rolling
IPC: B21B37/16
Filed: 1950-10-13
Abstract: 680,502. Control of several D.C. motors. MORGAN CONSTRUCTION CO. Oct. 13, 1950 [Oct. 27, 1950], No. 25017/50. Class 38 (iii) [Also in Groups XXII and XXXIV] In a strip rolling mill in which a number of roll passes 10-14, Fig. 2, are driven by separate electric motors 16-20 a reversible electric motor 42, Fig. 3, governing the supply of oil to the roll bearings is controlled according to the speed and thickness of the strip entering a given roll pass. In one example in which the motor 42 varies the, supply of oil and simultaneously changes the speed of the.strip, push ' buttons 53 or 54 closing solenoid operated switches are depressed to rotate the motor 42 in either direction. The motor 42 in addition to controlling the supply of oil further moves a a rheostat arm 44 controlling the field 47F of a supply generator for one of the mill roll driving motors 20 which is thereby simultaneously caused to reduce or increase speed. In another form of the invention in which the motor 42 is controlled simultaneously with changes in speed and thickness of the strip, manually controlled coupled rheostats 79, 80 Fig. 5. simultaneously varying the speed of a roll mill motor 20 by varying the field current of its supply generator 47 while causing the motor 42 to be rotated in one direction or the other by upsetting the balance in compensating fields 83F1, 83F2 of a supply generator 83 for the motor 42. The motor 42 moves the arm of a rheostat 81 which serves to bring the fields 83F1, 83F2 back into balance so that the motor 42 stops when the control arm reaches a predetermined position. Limit switches LSF, LSR adapted to be engaged at the limits of control movements to prevent overriding are arranged in series with rectifiers 84, 85 which permit supply of current to the motor 42 only in the reverse direction away from the limit. Control of the motor 42 according to the thickness of the strip is by means of a thickness gauge 56 Fig: 4, placed in front of the roll mill and generating a variable voltage in a Wheatstone bridge circuit 62. The variations are amplified by an electronic amplifier 74 which drives,.a,motor,7.6 in,either direction according 2o increase or decrease in thickness this motor moving rheostats 72, 77 which simultaneously rebalance the Wheatstone bridge and upset the balance. in the fields of the generator 83 driving the motor 42 which again as above rebalances the fields in the generator 83 by adjusting the rheostat 81 as it moves to control the supply-of oil. Further modifications are described in which either of the above systems for controlling the motor 42 simultaneously with changes in speed or with thickness of the strip are used alone. Specification 398, 332, [Group XXXIV], is referred to.
