  • Patent number: 5788155
    Abstract: This invention provides an air freshener dispenser device which consists of twin cartridges which are connected end-to-end with a flexible hinge means. The two cartridges can be folded together and incorporated in a dispensing holder as multiple refill units. Each cartridge is composed of a shallow tray which contains a volatile air freshener medium, and which has its open surface sealed with a coextensive bonded laminate of an inner vapor-permeable membrane and an outer peelable vapor-impermeable membrane. Removal of the peelable vapor-impermeable membrane sealing the two trays allows delivery of the air freshener medium as vapor into the environment at a controlled rate over an extended period of time.

  • Patent number: 5785254
    Abstract: A fuel injection valve has downstream a valve seat (23), an injector plate (23), which is characterized by having a plurality of swirl-producing elements on the intake side, followed by at least one uninterrupted annular gap in the downstream direction. The swirl-producing elements are arranged in a turbine vane-shaped form by each individual element running mostly radially and being tilted in the peripheral direction and the elements being arranged behind one another in a circular shape. The annular gap (45) represents the spray geometry. With this arrangement the fuel can be finely atomized without additional power consumption. The breakup into minute droplets results in further reduction of the exhaust emissions of an internal combustion engine and in lower if fuel consumption. The fuel injection valve is especially well-suited for use in injection systems of mixture-compression externally ignited internal combustion engines.

  • Patent number: 5785246
    Abstract: A variable flow sprinkler head having an inlet, an outlet and a nozzle, the nozzle having an orifice therein, the cross sectional area of the orifice being changeable by alternately inserting or removing a needle into the sprinkler head nozzle orifice. The needle diameter is sized to provide a predetermined flow rate reduction when the needle is inserted into the nozzle orifice. When the needle is removed full flow occurs. When the needle is inserted into the center of the nozzle orifice, the cross sectional area is effectively reduced by an amount equal to the cross sectional area of the needle. A linear actuator for the needle is centered above the outlet. The linear actuator may be either an electric solenoid or a hydraulic actuator. Alternatively, the linear actuator may provide a mechanism to allow the sprinkler to be operated between either of two preselected flow rates or in the alternative to be shut off completely.

  • Patent number: 5785245
    Abstract: A backpack sprayer for spraying arthropods or arthropod eggs, such as beneficial mites or beneficial insect eggs, or insect eggs containing parasitoids, directly onto plants is disclosed which uses excess air generated by a compressor to produce a coarse or fine spray of an aqueous suspension containing the arthropods or eggs as they exit from a spray gun. A stir bar magnet in a spray tank, controlled by a magnetic stirrer motor, keeps the arthropods or eggs evenly suspended in an aqueous solution. The sprayer provides an economical and alternative strategy for the delivery of arthropods such as beneficial mites and eggs to agricultural commodities.

  • Patent number: 5785249
    Abstract: A thrust reverser for a turbojet engine is disclosed having a rear duct portion extending about a longitudinal axis with a rearmost edge lying in a plane extending at an oblique angle to the longitudinal axis. The thrust reverser also has a single thrust reverser baffle pivotally attached to the rear duct portion to move between a forward thrust position and a reverse thrust position. The single thrust reverser baffle has rearmost, planar edge which, in the forward thrust position, forms the downstream or rearmost end of the engine nozzle. The planar edge eliminates the aerodynamic losses of the known thrust reverser devices. The thrust reverser baffle also has an oblique edge that faces in a forward direction and is parallel to the rearmost edge of the rear duct portion when the baffle is in its forward thrust position.

  • Patent number: 5785089
    Abstract: In accordance with one embodiment of the present invention, liquid material enters circumferencially into a generally cylindrical outer walled cylinder. A baffle may be provided to facilitate circumferencial flow. The tangential, circumferencial flow tends to reduce turbulence. In the outer chamber a top wall is provided and a cushion of air is located between the top wall and the top of the liquid medium to effect cushioning. After circumferencial flow, the liquid flows radially inwardly into an inner fluid chamber through a plurality of openings in an inner cylindrical wall. Within the inner chamber and spaced between the bottom wall and the top wall is a diffuser section. The diffuser section provides a large plurality of parallel fluid flow paths to dampen remaining major currents by lowering the fluid velocity and thus the Reynolds number. The upper surface is arcuate. Thus fluid flows radially upwardly and inwardly to a knife-edged type orifice which results in laminar fluid flow exiting therefrom.

  • Patent number: 5782410
    Abstract: An automatic continuous flow liquid dispensing device for dispensing liquid onto a receiving surface of an article includes an improved flow control mechanism comprising a threaded elongate shaft retained in threaded engagement by a base member securely attachable to the external housing, so as to be selectively rotatably movable to any one of a plurality of stop positions. The threaded shaft is positioned to be contactable by a valve of the dispensing device, thereby acting as a backstop to preclude the valve from reaching its full flow position, and thus defining a plurality of partial flow positions. An electric motor rotates the threaded shaft in first and second rotational directions, to selected stop positions. Electrical controls are connected in electrically conductive relation to the electric motor for selective control thereof.

  • Patent number: 5775585
    Abstract: A bin for holding a granular material has a conveyor belt in the bottom thereof. A plurality of separate conduits are in communication with the bin with each of the conduits having a discharge end. The conveyor belt meters the granular material from the bin into the conduits. A fan is provided for supplying flowing air through the conduits to blow granular material towards the discharge ends. Each conduit has a curved portion formed therein upstream from the discharge ends. Sensors are located in each of the curved portions to measure the centrifugal force of granular material moving through the conduits towards the discharge ends. Pivotal walls are provided in each conduit to adjust the flow of granular material therethrough. A microprocessor is connected to the sensors and the actuator to sense variations in the centrifugal force measured by the sensors, and to adjust the pivotal walls in one or more of the conduits to equalize the flow of granular material through the conduits.

  • Patent number: 5772116
    Abstract: A recirculating paint supply system supplies single or multiple paint coatings to paint spray stations arranged in parallel or series relation, each station including manually operated flexible monoline and coaxial conduits to supply paint to an improved spray gun. In one aspect of the invention, the improved spray gun is comprised of a polymeric material to reduce the overall weight of the spray gun thereby reducing operating fatigue and ailments caused by the use of conventional spray guns. In another aspect, the improved spray gun includes larger air passages which provides for a greater volume of air to pass through the spray gun, thereby providing increased atomization of the liquid coating composition. Thus, the reduced weight, as well as the increased atomization, increases the overall finish quality of the object being painted.
