Title: Process for preparing rubber hydrohalides
IPC: C08C19/16
Filed: 1956-07-09
Abstract: <PICT:0802238/IV (a)/1> In a process for preparing a hydrohalogenated rubber in which a solution of rubber is treated with a hydrogen halide, the unreacted hydrogen halide is removed from the rubber hydrohalide solution by passing through the latter the vapour of the rubber solvent.  Rubber hydrochloride may be prepared by dissolving rubber in a solvent, e.g. benzene, in a tank 1, and feeding the rubber solution to a reactor 5 where it is treated with anhydrous hydrogen chloride supplied through a pipe 6 from a tank 20.  When the hydrochlorination is completed solvent vapour, generated in a tank 15 is passed via pipe 16 through the rubber hydrochloride solution to remove the excess hydrogen chloride from the latter and carry it to a condenser 17.  The solvent condensed in the condenser 17 is returned to the reactor 5 or to the tank 15, and the hydrogen chloride gas passes through a pipe 18 to a recovery system 19.  The free hydrogen chloride in the rubber hydrochloride solution can be reduced to 0.2 per cent or less, and it may, if desired, be neutralized with ammonia or other neutralizer soluble in the rubber hydrochloride solution. The removal of the hydrogen chloride may be assisted by reducing the pressure in the pipe 18. The temperature at which the hydrogen chloride is removed is preferably regulated by circulating a cooling or heating liquid through the jacket 12 of the reactor 5, so that the concentration of the rubber hydrochloride solution remains constant throughout the removal period.  Alternatively, in a semi-continuous process the rubber solution is prepared in one set of tanks, run into a reactor for initial reaction with the hydrogen chloride, and then passed to a tank where the reaction is completed whilst a fresh bath of rubber solution is initially treated in the reactor.  The rubber solvent may, alternatively, comprise toluene, xylene, chloroform, or carbon tetrachloride.  U.S.A.  Specification 2,237,125 is referred to.

IPC: F01K23/10
Filed: 1952-08-25
Abstract: 738,286. Steam turbines. BABCOCK & WILCOX, Ltd. Aug. 24, 1953 [Aug. 25, 1952], No. 21290/52. Class 110 (3). [Also in Group XIII] A steam power plant comprises a steam generator which has a high-pressure section 10 and a low-pressure section 13, the sections being located one above the other in a vertical duct 4 and being heated by a downward flow of combustion gases from an oil-fired combustion chamber 2, the gases first passing through a gas turbine 3 which drives a compressor 1 supplying air to the oil burners. The high- and low-pressure boilers consist respectively of inclined steam-generating tube banks 10, 13 which extend between drums 11, 8 and 14, 9. The high-pressure steam from drum 8 passes through a superheater 6 to the high-pressure stage of a steam turbine 28 driving an electric generator 31 whilst the low-pressure steam from drum 9 passes via a superheater 7 to the low-pressure stage of the turbine. Exhaust steam from the turbine is led to a condenser 30, the condensate being returned to each boiler section via economisers 21, 22 by a feed water pump 26. The turbine shaft speed is kept constant over the load range thereof by a governor valve 32 in the high-pressure steam supply line, the pressure at the outlet from superheater 6 being maintained at a constant value by a control 33 which adjusts the firing rate in combustion chamber 2. To prevent the combustion gas temperature at the outlet from duct 4 from falling below the dewpoint whilst maintaining it at an economical low value, a temperatureresponsive element 23 is located in the duct outlet and controls a throttle valve 34 in the outlet line from the low-pressure superheater 7. If for example a change in firing rate causes the gas temperature at 23 to rise, valve 34 is opened, the pressure in boiler section 13 falls and the gases give off more heat to this section, the temperature at 23 thus being restored to the desired value.

Abstract: 759,567. Controlling aircraft. GIRAVIONS DORAND. July 22, 1954 [Aug. 5, 1953], No. 21430/54. Class 4. A control aid to be interposed between a control and a controlled member, e.g. the control column and a movable surface in an aircraft, comprises a correction system including retarding means 1 (Fig. 4) directly interposed between said control and controlled members 5 and 6, adapted to connect the same in a substantially positive manner during quick displacements of the control member 5, a displaceable anchoring member 46 and first return-to-neutral elastic means 2 connected between member 40 and controlled member 6, and a resetting system including means to shift said anchoring member 46 with respect to said controlled member 6 in the direction in which the latter has been displaced by said control member 5, the shifting means comprising second return-to-neutral elastic means 2<SP>1</SP> operatively connected between said control member and said anchoring member and retarding means 11 to control the action of said second elastic means on said anchoring member. In Fig. 4, each retarding means comprises a dashpot. In operation, a displacement of member 43 to which rod 5 is secured, results in the first instance in a similar displacement of member 6, putting spring 2 in tension. The spring will then contract, under the retardation of dashpot 1, 4 and member 6 is slowly returned to its former position. In the meantime, rod 51 also secured to member 43, has compressed spring 2<SP>1</SP>, which under the retardation of dashpot 11, 4<SP>1</SP> sets a new neutral position of the anchoring plate 46, which has an aperture 47 for the free passage of rod 5. The neutral position of rod 6 to which it is returned by the system of spring 2 and dashpot 1, 4 is thus reset by the anchoring plate 46. The time constant of spring 21 and dashpot 11, 4<SP>1</SP> is preferably greater than that of spring 2 and dashpot 1, 4. In Fig. 6, the dashpot 1, 4 is replaced by a rotary dashpot 17, and the dashpot 1<SP>1</SP>, 41 by a flywheel 16. The spring 2<SP>1</SP> acts on a rack 13 adapted to rotate a cog 14 on a shaft 15 carrying the flywheel 16 and a worm 18, rotation of which traverses a nut 14 forming the anchoring member for spring 2. In Fig. 5 (not shown), a modification of Fig. 6, the dashpot 1, 4 of Fig. 4 is retained and the dashpot 1<SP>1</SP>, 4<SP>1</SP> is replaced by a rotary dashpot, and irreversible gearing comprising two-worm mechanism is disposed between shaft 15 and the anchoring member of spring 2. In Fig. 7 (not shown), a further modification of Fig. 6, the dashpot 1, 4 is retained, and the nut 19 acts on spring 2 through a bell-crank lever.
