  • Patent number: 4474327
    Abstract: A fertilizer spreader includes an attachment assembly for use with a portable hand-held air blower for entraining granular fertilizer or the like into the discharge air stream of the blower, whereby the fertilizer is broadcast by the air stream over a lawn or garden area. The attachment assembly comprises an adapter nozzle connected in-line with the discharge air stream of the blower and including a pressure port through which a portion of the discharge air stream is directed for passage through a pressure tube to a diffuser mounted within a portable vented fertilizer-receiving container near the bottom thereof. The diffuser turns the air stream upwardly within the container and divides the stream into a plurality of turbulent air flows for agitating and suspending particles in a localized region above the diffuser, with a substantial portion of the air stream escaping from the container through a vent at a position remote from the localized region.

  • Patent number: 4473191
    Abstract: An elongated fluid distributing hose for use in an irrigation system for plants, vegetables, and the like. The hose incorporates a particular arrangement of a main supply channel for gross water movement, and a water distributing network for fine water movement. Water pressure reduction takes place in the water distributing network at the point of the passing of the water from the high pressure main supply channel through a series of first fluid-passing openings or inlet stations through one or more smaller fluid-restricting passages. In certain embodiments, a structure is provided to perform a pressure regulating function in each of the smaller passages. In one embodiment, pressure reduction between an inlet and an outlet is by way of serpentine fluid-restricting path. A novel method and machine are employed to manufacture the various hoses embodying the teachings of the subject invention.

  • Patent number: 4441656
    Abstract: An electrostatic spray gun is provided with electrostatic power circuitry for supplying high voltage power to an electrode with a switch for enabling and disabling the circuitry, the switch being operated by movement of a trigger controlling flow of a coating fluid through the spray pistol. The switch is a magnetic switch normally open, but closeable by a magnet positioned adjacent the switch, the trigger having means to shunt the magnetic field allowing the switch to open when the trigger is closed and allowing the switch to close when the trigger is open. A second magnet is provided movable towards and away from the first magnet whereby the second magnet effectively shunts the magnetic force of the first magnet when moved adjacent thereto to prevent closure of the switch independent of movement of the trigger.

  • Patent number: 4436247
    Abstract: A diesel fuel injection nozzle and holder assembly includes a tubular nozzle holder carrying a nozzle on one end and defining, in combination therewith, a storage chamber for receiving successive charges of fuel under pressure via a check valve mounted therein. A needle valve, complete with a stem, mounted in the storage chamber is urged by a first spring toward a position for closing spray orifices in the nozzle. Disposed opposite to the end of the needle valve stem, a yieldable abutment is biased by a second spring toward the stem and normally retained a preassigned distance away therefrom. When acted upon by each pressurized fuel charge trapped in the storage chamber, the needle valve is unseated to open the spray orifices against the force of the first spring if the fuel pressure is relatively low, and against the resultant of the forces of the first and second springs if the fuel pressure is higher.

  • Patent number: 4434938
    Abstract: The present invention presents an aroma system for use with toilets and the like. In the present aroma system an improved pump has been combined with a container to provide a compact and trouble-free system. The pump is activated by the toilet handle when the toilet is flushed. Pump activation releases a preselected aroma which will mask the normal toilet odor. Provision is made for the removal of the pump and container combination from the toilet for servicing and refilling. Removal is accomplished by unfastening a special fastening device which is designed to be tamper proof.

  • Patent number: 4423839
    Abstract: An alignment control system for lateral irrigators. The alignment control system includes a dampening feature which monitors changes in the lateral displacement of the master and wing of the irrigator relative to each other and based thereon, operates the irrigator to dampen not only the lead-lag oscillations of the wing relative to the master but also the left-wing oscillations of the master about its preferred line of travel. A zero thrust expansion joint is also disclosed which enables the lateral displacement measurements at the joint to be independent of the force of the water pressure in the irrigator tending to push the master and wing apart. The zero thrust expansion joint includes a flexible member whose sides match the cross-sectional area of the pipes of the irrigator. The interior of the flexible member is in fluid communication with the water in the pipes and each side of the flexible member is attached to respective ones of the pipes at the joint.

  • Patent number: 4418867
    Abstract: An electrically controlled unit injector for a diesel engine wherein both timing of injection and the quantity of fuel premetered into the injector are controlled by a single solenoid. The control of the timing portion of the cycle is accomplished by a timing port of the valve which, when open, permits fuel to flow into the timing chamber and, when closed, operates against high pressure to shut off the flow of fuel from the timing chamber. The metering function is initiated by the upward travel of a metering plunger in response to the upward travel of a pumping plunger while the timing port of the valve is closed. Metering is terminated by a metering port of the valve which shuts off the supply of fuel to the metering chamber. The timing and metering ports of the valve are controlled by the single solenoid. Metering quantity control may be of the pressure-time or volumetric metering type.

  • Patent number: 4413785
    Abstract: A variable pressure wand or gun for connection to the flexible conduit of a pressure fluid cleaning system such as used in car washes and the like. Parallel high pressure and low pressure barrels are connected by a fluid passage having a normally open pressure fluid discharge valve plunger therein. A selectively hand operable grip and lever are provided for closing or seating the valve plunger against fluid pressure in the system, the degree of closing being proportional to the force applied to the grip. The high pressure barrel is equipped with a spray or jet nozzle and the flow of fluid to the low pressure barrel is controlled by the operation of the valve plunger.
