Abstract: PRECISION FUEL INJECTION APPARATUS            ABSTRACT OF THE DISCLOSURE          A fuel injection control system and technique for an internal combustion engine is disclosed having at least one controlled offset fuel injector valve and only one controlled trim injector valve.  The offset injector valves produce a constant quantity of fuel by being energized for a fixed pulse duration each injection cycle while the difference between that constant quantity and a desired fuel injection quantity calculated from a fuel schedule is supplied by the variable trim injector.  The fuel supply schedule is determined by the engine variables of the operating system by an electronic fuel scheduler circuit which further supplies fuel injection timing pulses for triggering the begining of the injection cycle.  An alternate embodiment discloses using an electromechanica? distributer to select which of the offset fuel injectors are energized during an injection cycle and a third embodiment illustrates the use of the fixed pulse width associated with the offset injectors to enable the selection process of the electromechanical distributor.

Title: Method for controlling flocculant addition to tar sand tailings
Inventor: FUHR BRYAN J
IPC: C10G1/04
Filed: 1979-11-21
Granted: 1982-03-16
Abstract: "METHOD FOR CONTROLLING FLOCCULANT ADDITION TO TAR SAND TAILINGS" The hot water extraction process for recovering bitumen from tar sand produces a large volume of solids-laden aqueous tailings as a waste product. The solids in the tailings stream may be flocculated by the addition of lime and the components of the stream then separated into a water-free solids phase and a clarified water phase. During flocculation, the zeta potential of the stream is monitored. It rises from an initial negative zeta potential, as the lime is added. Flocculation is terminated when the zeta potential is about zero. At this point, the tailings are in optimum condition for separation into the water-free solids phase and the clarified water phase. Separation is preferably effected by vacuum filtration.
