  • Patent number: 5626296
    Abstract: A quick reacting air spreader apparatus for transporting particulate solids includes an improved vertical auger assembly disposed within a cylindrical auger housing. The auger assembly includes a substantially continuous auger flighting rotatably coupled to a circular shaft and further includes at least one baffle assembly pivotally coupled to either a bottom surface of the flighting or to the circular shaft at predetermined locations selected to provide a desired or required loading on the vertical auger. Upward vertical movement of the particulate solids through the vertical auger open baffle assembly baffles and downward vertical movement of the particulate solids through the vertical auger close baffle assembly baffles thereby blocking further downward vertical movement of any particulate solids remaining above the baffle assemblies.

  • Patent number: 5556034
    Abstract: A fuel injection valve is provided which produces good atomization of fuel and increases the accuracy of the distribution rate of the fuel to a pair of diverging injection holes, even when the amount of assist air is decreased. The fuel injection valve includes a valve housing having a pair of diverging injection holes which diverge from each other in the forward direction with respect to a junction disposed in front of a fuel injection hole. The valve housing is provided with air supply passages for supplying assist air to a fuel flow injected from the fuel injection hole. A pintle inserted through the fuel injection hole has a tip end portion reduced in diameter in the forward direction and is coaxially connected to a valve member. The diameter D of the fuel injection hole, the width W of the junction in a plane intersecting axes of the diverging injection holes and the distance L from the fuel injection hole to the junction are determined to satisfy relations, 0.04<W/D<0.4 and 0.5<L/D<10.

  • Patent number: 5556031
    Abstract: A fuel injection nozzle has a valve member engageable with a seating to prevent fuel flow through an outlet orifice. The valve member is engaged by the narrower end of a stepped piston member the surface of which remote from the valve member is subjected to fuel under pressure to bias the valve member into engagement with the seating. A tubular valve element the interior of which is connected to a drain, is engageable with the surface but can be moved away from the surface to lower the pressure applied to the surface. The valve member lifts away from the seating when the pressure applied to the surface is reduced by fuel pressure acting on a further surface defined on the valve member. The valve element is connected to the armature of a solenoid.

  • Patent number: 5553781
    Abstract: A standard jerk type fuel injector can be converted to an accumulator type fuel injector by modifying internal flow configurations of the injector from ones which lead to injection whenever fluid pressure in a fuel supply passage thereof exceeds a first designated level to ones which present an accumulator and a control cavity and which lead (1) to injector charging when the fluid pressure in the supply passage exceeds a second designated level and (2) to initiation of injection only upon subsequent pressure decay in the supply passage below a third designated level. The conversion can advantageously be performed by replacing a first spacer having a first set of flow configurations with a second spacer having a second set of flow configurations including a non-return element. The resulting injector has (1) an accumulator volume located fluidically downstream of the non-return element and (2) a control cavity above the nozzle needle.

  • Patent number: 5553778
    Abstract: A nozzle suitable for use with a device for removal of deposits from contaminated surfaces, such as a sootblower in a heat recovery boiler, is designed to avoid normal shock wave formation, and hence energy dissipation, by achieving a condition whereby, the emergent steam pressure (p.sub.e) is related to the ambient pressure (p.sub.oo) by the relationship p.sub.e /p.sub.oo <about 2, preferably about 1. A compact design achieving this result and able to function over a wide range of flow rates comprises a cylindrical body with a downstream convergent outlet and a rounded-head conical insert located axially in the body with its maximum dimension generally coinciding with the commencement of convergence of the outlet and extending through the outlet.

  • Patent number: 5540384
    Abstract: An ultrasonic spray coating system includes a converter which converts high frequency electrical energy into high frequency mechanical energy thereby producing vibrations. The converter has a resonant frequency. A spray head is coupled to the converter and is resonant at the resonant frequency of the converter. The spray head has an atomizing surface and a feed blade to the atomizing surface and concentrates the vibrations of the converter at the atomizing surface. A source of high frequency alternating voltage is electrically connected to the converter and produces a controlled level of electrical energy at the resonant frequency of the spray head and converter whereby the atomizing surface is vibrated ultrasonically. A fluid supply applicator is in close proximity with the feed blade to the atomizing surface and spaced therefrom.

  • Patent number: 5539952
    Abstract: The present invention is an air operated fluid handling apparatus for cleaning lithographic presses. It provides a printing press operator with a device for both dispensing ink solvents and removing spent fluids used in the printing process. Compressed air is regulated and directed to a T-section connector. One conduit extends from the connector to provide pressure in an ink-solvent container. Another conduit extends from the connector to a venturi which is used to create a vacuum in a used-fluid container. A conduit extends from each container and connects to a light weight flexible hose. Connected to the opposite end of the flexible hose is a valve and nozzle assembly that allows the press operator to alternate between dispensing ink solvent and remove spent fluid. With this apparatus the press operator can effectively move from printing head to printing head dispensing ink solvent and removing used fluids as necessary for ink train and dampening system cleanup.

  • Patent number: 5540387
    Abstract: A device has a jet divider with a convex divider surface facing the perforated spray disc. The convex jet divider acts as a flow resistance, thereby causing stagnation region flow. The stagnation-region flow is responsible for the fact that, despite the gas containing, separation of the jets is maintained even downstream of the jet divider (86) and for the good preparation effect of the gas containing by virtue of improved mixing of the gas and fuel. The device for injecting a fuel/gas mixture is suitable particularly for injection into the intake pipe of a mixture-compressing internal combustion engine having externally supplied ignition.
