Title: Altitude compensated fuel control system
IPC: F02D1/06
Filed: 1976-03-18
Abstract: 1501055 Controlling IC engines CATERPILLAR TRACTOR CO 18 March 1976 [25 Aug 1975] 10934/76 Heading F1B An altitude compensated fuel control system for an I.C. engine comprises a control member 11  for controlling fuel flow to the engine, and means for controlling the position of the fuel control member including a stop 58 for limiting movement of the control member towards an increased fuel flow direction to provide a maximum fuel flow position of the fuel control member for a given atmospheric pressure, there being means responsive to atmospheric pressure change for adjusting the maximum fuel flow position of the fuel control member with changes in atmospheric pressure so that the maximum rate of supply of fuel to the engine decreases with increase of altitude. Decreased atmospheric pressure either acts directly on a bellows 113, Fig. 3, or causes a turbocharger 123 to produce lower boost pressure, which acts on the bellows 113 so that a spool 91 descends to reduce the size of opening to a bleed passage 107, thereby increasing fluid-pressure in a chamber 98. This pressure acts also in a chamber 83 on a piston 76 to rotate a lever 84 counterclockwise, as seen in Fig. 3, which rotates a pivot shaft 62 having an eccentric portion 66 on which is mounted a bell crank 67 in such a way that counterclockwise rotation of shaft 62 turns control member 11 counter-clockwise as viewed from the left of Fig. 1 to reduce the maximum fuel supply rate for the given altitude. During operation at a fixed altitude, the position of a tubular member 43 is determined by flyweights 30. Increased engine load slows the flyweights so allowing member 43 to move rightwards (until a lip 44 engages stop 58) rotating the bell crank 67 counter-clockwise, as viewed in Fig. 2 (not shown), to cause clockwise rotation of the control member 11 to increase the fuel supply rate.

IPC: B01D53/14
Filed: 1965-03-16
Abstract: A process for the separation of CO2 and/or H2S from gaseous mixtures comprises passing the mixture through an absorber in contact with an absorbent liquor comprising an aqueous solution of an alkali metal salt of a weak acid, passing the liquor containing dissolved CO2 and/or H2S into a regenerator where the liquor is heated and stripped with steam to regenerate the liquor and liberate the acidic gases which pass with steam to a cooler/collector and then to a separator/accumulator followed by a second such arrangement returning all the first condensate and at least part of the second to the regenerated liquor, preferably to the upper part of the regenerator containing a packed zone. The surplus condensate from the second separator/accumulator may be treated for desorption of acidic gases and used as boiler feed water.  Preferably a zone of fine packed material, e.g. wire gauze, is included after the first separator/accumulator to remove entrained absorbent liquor which is returned to the first separator/accumulator.  Specified alkali metal salts are potassium carbonate and tripotassium phosphate.
