Title: Carburettor having a throttle valve positioner
IPC: F02M3/06
Filed: 1972-06-09
Abstract: 1342566 Spray carburettors FORD MOTOR CO Ltd 9 June 1972 [26 July 1971] 26968/72 Heading F1B A carburettor has a throttle valve movable by a throttle valve positioner 42 from a closed position 34 through an idle speed position 36 to a wide open position and an idle mixture by-pass 26 connected at a position 30 traversed by the throttle valve. A first plunger 78 moves or restricts movement of the throttle valve and is spring biased beyond the idle position for lean mixture hot starting in opposition to a first intake vacuum responsive servo which retracts the first plunger permitting the rotation of the throttle valve to an anti- "running-on" position 34 and a second plunger 72, controlled by a second intake vacuum responsive servo, which alternately prevents movement of the first plunger beyond a third position permitting rotating of the throttle to an idle position giving richer mixture or permits movement of the first plunger to the anti- "running-on" position. In the engine starting position shown cranking causes the intake manifold vacuum to act on diaphragm 54 via passage 88 and chamber 60 to pull retainer 74 against partition 50. The vacuum leak through orifice 100 permits ambient pressure in chamber 58 and spring 40 to move diaphragm 54 and plunger 78 until stopped by plunger 72 for the idle speed position 36 in which idle mixture by-passes the throttle via passages 26, 30. When the throttle valve is opened manually the spring 82 moves plunger 78 back to a start position away from plunger 72. If the engine is shut off the vacuum in chamber 60 quickly decays permitting plunger 72 to be freely positioned. Since communication between vacuum chambers 60, 62 is restricted via orifice 100 the vacuum in reservoir 92 together with spring 40 pulls plunger 78 to the left to permit full closure of the throttle to position 34 preventing any "running-on". After a delay the decay of the vacuum in reservoir 92 permits spring 82 to reposition plunger 78 thereby locating the throttle valve in the fast idle position 37 for subsequent starting.

Title: Oil recovery process utilizing steam
IPC: E21B36/00
Filed: 1973-06-07
Abstract: 1407889 Wells &c TEXACO DEVELOPMENT CORP 7 June 1973 [30 June 1972] 21737/73 Heading E1F [Also in Division B1] A method for recovering oil from a subterranean formation comprises mixing at elevated temperature and pressure a heavy hydrocarbon and feed water, such as brine, containing dissolved solids to give a water-hydrocarbon phase substantially free of solids and a water phase, separating the two phases, reducing in pressure and heating the water-hydrocarbon phase to form a steam phase and liquid hydrocarbon phase, separating the steam phase from the liquid hydrocarbon phase, and injecting the steam into an injection well 36. The hydrocarbon, which is preferably eicosane, is initially heated in a heater 12 to a temperature at which it assumes a high affinity for water, the hot hydrocarbon being then fed into the lower portion of a column 16. Brine is sprayed into the top of the column by means of a sprayhead 20 and passes downwardly through the upwardly flowing hot hydrocarbon. The interaction of the two streams causes the solid-free homogeneous water-hydrocarbon phase to be formed, and this phase is withdrawn through line 26. The steam and hydrocarbon are separated in a separator 48 and the hydrocarbon is recirculated via a pump 51. Solids precipitated in the column 16 descend to a sludge chamber 30 and the concentrated mixture formed therein is fed through a heat exchanger 32c to preheat the incoming brine.

Title: A method of and apparatus for classifying solid particles
Inventor: SHARPLES THOMAS DAVY
IPC: B07B7/08
Filed: 1962-07-16
Abstract: 941,170. Centrifugal classifiers; deagglomerating. SHARPLES CORPORATION. July 16, 1962, No. 27181/62. Headings B2A and B2P. Finely divided solid particles are classified by the opposite actions of centrifugal force and an inward fluid current by causing the fluid to rotate with a radially inward flow component in an annular classifying zone and laterally feeding the particles into the fluid under shear stress and in the form of an annulus rotating in the same general direction as the fluid and in which the particles are substantially uniformly distributed. The classifying zone 17, Fig. 1, lies between the walls of stationary annular members 13, 15, 37 and of the rotor which comprises parts 34, 41, 44. The particles are fed from a funnel 25 through a tube 26 into a chamber 47 defined between the rotor parts 34, 44, travel through radial channels 42 in the rotor and are projected against a wear ring 52 of tungsten carbide cemented on the annular member 37. Relative rotation between the rotor part 41 and the ring 52 produces shearing action whereby the particles are deagglomerated and uniformly distributed in gap 51 to enter the zone 17 in the form of a rotating annulus. Air passing through adjustable whirl vanes 23 enters the zone to rotate in the same direction as the rotating annulus. Air and the relatively fine particles pass from the zone into a stationary annular chamber 56 and are led to a bag filter 59 which is connected to a fan 57 causing the current through the apparatus. The coarse particles thrown outwardly by centrifugal force pass through a tangential opening 61 into a chamber 62 from which they are withdrawn through an outlet 63. Wear-resistant material, such as tungsten carbide or ceramic tiles, is used at 16, 81, 82, on the bottom of chamber 47 and as linings for the rotor channels 42. The ring 52 may be set parallel to the rotor axis or at such an angle as to impart radially inward or outward movement to the particles as they enter the zone 17. The speed of rotation of the particles is approximately the same as that of the fluid around the area of the gap 51. The rotor is mounted on a spindle 32 journalled in bearings in a housing 31 and rotated through a pulley 33. In a modification, Fig. 5, the classifying zone 77 is bounded by stationary walls, the rotor being in the form of a laterally extending annular member 75 integral with a spindle 74. In a further modification, Fig. 6, wear ring 83 is provided with an inwardly extending lip 85 at the entrance of the particles to the classifying zone. Performance figures for the classification of limestone powder and hydrated alumina and dimensions of the apparatus are given. Specifications 675,365 and 795,494 are referred to.
