Title: Improvements in or relating to the sweetening of petroleum products
IPC: C10G27/10
Filed: 1954-11-26
Abstract: Petroleum fractions are sweetened by oxidizing the mercaptans therein in the presence of a chelate organo-metallic compound, and either a lead salt or an alkali metal plumbite.  The chelate compound may be formed in situ in the fraction, in which case an alkali, e.g. caustic soda, may be added to neutralize acid generated in the reaction. Chelate compounds referred to are cobalt bis-(disalicylal ethylene di-imine) and cobalt disalicylal 1,2-propylene di-imine, which may be prepared from the amine and cobalt nitrate, naphthenate, or acetyl-acetonate.  The chelate may be added as an aqueous or aqueous-alcoholic dispersion, for example in an aqueous solution of "Teepol" (Registered Trade Mark), or may be dissolved in a solvent such as methanol.  Lead salts referred to are salts of organic acids such as naphthenates, phenolates, cresolates and mercaptides. Alternatively, the process may be carried out in apparatus made partly of lead, in which case part of the lead, in the presence of aqueous alkali, is converted into plumbite.  Examples are given of the treatment of a mixture of cracked and straight run petroleum spirit, straight-run petroleum spirit, kerosene and gas oil.  The process may be operated continuously.  Specifications 701,443, 767,587 and 782,052 are referred to.

Title: Improvements in or relating to ride levelling systems for road vehicles
IPC: B60G21/10
Filed: 1957-11-08
Abstract: 835,335. Adjusting vehicle height. FORD MOTOR CO. Ltd. (Ford Motor Co.). Nov. 8, 1957, No. 34834/57. Class 108(2) [Also in Group XXXV] A levelling system for a vehicle comprises level-sensing means for completing a control circuit to operate vehicle raising or lowering means when the vehicle is unlevel, the control circuit including parallel-connected normally-open limit switches which are closed individually by the opening of a vehicleloading entrance, a hold-in means being provided to bypass the switches when one of them is closed and the vehicle is unlevel. In one embodiment, closure of a manuallyoperated switch 35, energizes a hold-in relay 36, through the left-hand contact 52-1 of relay 52 if one of the vehicle doors is open to close one of the normally-open switches 11 . . .15, or if a manually-operated switch 16 is closed or if switch 10 is closed due to a pressure differential in the two air vehicle suspensions 47, 48. Contact 36-1 is thereby closed to hold the circuit through relay 36. The circuit of relay 52 is also completed if the vehicle is stationary (switch 19 closed) and level (switch 20 closed) and the brake is applied (switch 28 closed). The signal lamp 53 is energized in the same circumstances. The relay 52 operates its contact 52-1 to its right-hand position to de-energize the hold-in relay 36 unless the vehicle frame is too high (switch 37 closed) or too low (switch 38 closed). When all the loading entrances have been closed series switches 21...25 are all closed and if the vehicle frame is high (switch 26 closed) an actuator coil 27 is energized, or if it is low (switch 29 closed) actuator 30 is energized. The actuator 27 opens air-valves 27-1, 27-2 to bleed air from the suspensions 47, 48 to the reservoir 42 until the vehicle frame has dropped to the correct level when switch 26 opens to de-energize actuator 27 and switch 37 opens to de-energize the holding relay 36. Contact 36-1 then opens and extinguishes the lamp 53. The actuator 30 closes contacts 30-1 to energize the motor 33 driving the air-pump 40 and open airvalves 30-2, 30-3 to allow air to be pumped into the suspensions 47, 48. When the vehicle frame has risen to the correct level the system closes down as before by the opening of switches 29, 38. In another embodiment, Figs. 4 to 9 (not shown), the level-sensing is performed by pneumatic valves in a system supplied from a compressed-air reservoir.

Title: Improvements in or relating to output torque control in internal combustion engines
IPC: B64D31/02
Filed: 1945-12-31
Abstract: 613,050. Automatic control of internalcombustion engines. MORGAN, F. W. Dec. 31, 1945, No. 35278. [Class 38 (iv)] A control system for an internal-combustion engine, more particularly for aircraft, is adapted to maintain an optimum output torque by deriving an electrical response of a value dependent on the output torque and a second opposing response of a value which can be varied by a manual control, the resultant response being arranged to actuate an engine control element capable of varying the output torque so as to counteract any change therein and, in addition, the manual control is coupled with a further engine control element, e.g. an engine speed governor, in such a manner that the manual control can be moved to adjust the speed governor without altering the value of the said second response. The system includes an electro-responsive torque element 1 which produces an E.M.F. of a value dependent on the output torque of the engine and may comprise a unit consisting of two A.C. generators fitted at two positions on the crank or gear shaft and providing an E.M.F. proportional to the angle of twist of the shaft and hence to the torque transmitted by it. This unit is connected in series with a resistance 8. The power output of the engine is dependent on the setting of a lever 2 which can be moved to vary the controlling effect of a device such as the engine speed governor, and at the same time moved over contact sectors 3, 4, 5 whereby steps of a resistance 7 are cut in or out of a circuit including a battery 6 and resistance 9. The resistances 8 and 9 are connected in a balancing network, with their respective currents in opposition, so that any change in the balance is applied over lines 11, 12 to a solenoid or servomotor 13 which is geared to the throttle valve or boost-control unit 14. When in contact with the sector 3 the lever 2 is set for the cruising range and the engine develops optimum torque to maintain the system in equilibrium, and the lever can be moved within the full extent of the sector to alter the governor or other control connected thereto to vary the speed without altering the output torque. Sector 4 may correspond to the " climbing " position, and movement of lever 2 on to this produces unbalance of the circuit so that the motor 13 actuates the throttle valve to alter the output torque of the engine and restore the equilibrium of the system. Contact 5 may correspond to an emergency condition for increasing the torque output. The arrangement may be modified by providing manual regulation of the throttle valve and operating the propeller governor control by the motor 13. The electrical bridge network may contain amplifiers, rectifiers, transformers or potentiometers to establish balance and provide the power to actuate the control element 13 either directly or through a relay.

Title: Improvements in or relating to engine governors
Inventor: WALFORD ALEXANDER GEORGE
IPC: G05D13/00
Filed: 1957-11-12
Abstract: 852,688. Fluid-pressure servomotor-control systems. DAVEY, PAXMAN & CO. Ltd. Nov. 4, 1958 [Nov. 12, 1957], No. 35284/57. Class 135. A centrifugal governor acts on the fuel controlling means of an engine through a fluidpressure servomotor which is provided with a fluid-pressure feedback connection having means for varying the steady state feedback pressure to vary the equilibrium speed of the governor so as to obtain any desired value of speed droop, positive or negative, or isochronous running. As shown, flyweights 4, which oppose an adjustable speeder spring 3, act on a pilot valve 9 which controls a servopiston 22 and is fed by an accumulator 16 and pump 11 which, with the flyweights, is engine-driven through change-speed gears 12. The valve 9 and a sleeve 10 in which it operates are relatively rotatable to minimize friction. The servopiston 22 is continuously supplied on its upper, annular surface with pressure fluid and is connected to a fuel controlling lever 23 which is linked to levers 25, 44 connected respectively to an abutment 26 for a loading spring 27 of a droop control valve 29 and to a basic droop piston 39. The fulcra 41, 34 of the levers 25, 44 are adjustable by knobs 36, 37. For applying the fluid-pressure feedback to the pilot valve 9, pressure fluid is passed through a restriction 28 and an integral action control valve 40 to a conduit 45 which leads through a receiver containing a spring-loaded piston 18 to the lower end of the pilot valve. Alternatively, the feedback pressure may be applied to the end of the sleeve 10. The steady state feedback pressure is determined by the spring- loading of the valve 29 which controls a relief outlet between the restriction 28 and valve 40. When the servopiston operates it moves the piston 39 in a direction such that the fluid displaced thereby causes a change of pressure in the conduit 45 such as to oppose the movement of the pilot valve 9 that initiated the operation. After a time this pressure leaks away so that the remaining feedback pressure is that determined by the valve 29. To obtain isochronous governing the fulcrum 41 is so adjusted that the compression of the spring 27 is not varied by movement of the servopiston. A loadsensing unit for reducing frequency variations in an alternator driven by the governed engine may be connected at 42 to the conduit 45. This unit may include a wattmeter controlling a piston movement of which affects the pressure in the feedback conduit 45. For shutting down the engine a pilot governed valve under the control of a solenoid is used to release pressure from below the servopiston 22.
