Abstract: An apparatus for folding an outboard boom on a liquid spraying element is disclosed. The apparatus (20) both folds a portion of the boom (14) while simultaneously operating a valve device (22) controlling liquid ejection device (78) mounted on the folded portion (18) of the boom (14). In this fashion, boom (14) has an operational capability at both a longer and a shorter span width.

Abstract: A spreader of granulated and liquid material, for a vehicle comprises, a granulated material vessel having three feed troughs extending substantially along a longitudinal axis of the vehicle. A conveyor with hydraulic motor is positioned in each feed trough and feeds granulated material to three distributor units. A liquid material vessel is also provided which includes liquid supply lines to each of the distributor units. Each liquid supply line has a hydraulic motor-powered pump. Two of the feed troughs which are positioned on either sides of the longitudinal axis of the vessel include granulated material feed lines connected between the respective feed trough and its associated distributor unit so that a distributor plate of each of the associated distributor units is positionable beyond the side contours of the vehicle, and on either side of the vehicle, to increase the potential width of coverage with the spread material.

Abstract: A particle spreading apparatus for use in evenly dispersing particles such as grain upon introduction of such particles within a particle storage bin. The apparatus includes a rotating drum having output ports and output tubes affixed thereto through which the particles must pass to enter the bin. The tubes are of varying lengths and at varying angles to the horizontal plane, thereby encouraging even distribution of the particles throughout the particle storage bin. Each output port opening may be selectively varied.

Abstract: A flotation nozzle is described as having an enclosed chamber with unique fluid emitting orifices which are angularly oriented to produce a desired, directional flow of fluid. One such orifice is a dimple-shaped cavity which extends inwardly of the chamber and has a circular opening in the downstream portion of the dimple, relative to the flow of fluid in the chamber. The opening is tilted so that the direction in which the fluid flows from the opening substantially coincides with the resultant velocity vector of the velocity vectors due to static and dynamic fluid pressures at the orifice.

Abstract: A sprayer spraying liquid or pulverulent substances, particularly fire-extinguishing or fire-inhibiting substances, comprises a tank adapted to hold the substance to be sprayed, a sprayhead, a rising pipe extending from said tank to said sprayhead, and a pressure vessel, which contains a gaseous fluid and communicates through a shutoff valve with the tank.

Abstract: A dispenser for spraying fragrances in an automobile has a housing with a compartment defined therein and a slot-like aperture in the top thereof. Fragrance-filled containers are positioned horizontally in the compartment in parallel side-by-side relationship. Each container has valve means actuatable to dispense a spray of its fragrance from an orifice thereof upwardly through the slot-like aperture. Two spaced apart front walls support members for selectively actuating the valve means to spray a selected fragrance into the atmosphere.

Abstract: The present invention relates to a boom suspension and lift assembly which is mounted to extend laterally from a vehicle for agricultural spraying purposes. The boom assembly comprises a main frame mounted on the vehicle and at least one boom pivotally mounted on the main frame. A suspension system between each boom and the main frame independently absorbs boom motion resulting from vehicle travel over uneven terrain. A boom lifting system is provided to selectively lift each boom relative to the main frame by pivoting the boom about a longitudinal axis adjacent the main frame. For transport or storage, each boom is foldable against a side of the vehicle.

Abstract: A fuel pump-injector unitary assembly comprises a plunger slidable in a bore and provided with a longitudinal passage-way, in combination with a metering ring surrounding the plunger and housed in an annular chamber of the injector body. The plunger is movable into a first or upper postion in which fuel is admitted into the lower part of the injector bore through an inlet port, and a second or lower position in which the tapered lower end of the plunger obturates fuel spray nozzles provided at the bottom of the bore. Fuel metering results from the cooperation of an inclined ramp of the ring with a fuel discharge duct transversely extending through the plunger and connected with the longitudinal passage-way thereof. Relative rotation of the metering ring and of the plunger permits adjustment of the injected fuel charge.

Abstract: A fluid injector, for example for injecting liquid fuel into a combustion chamber, comprises a valve housing and an injector assembly removably mounted on the valve housing. The injector assembly includes discharging means for discharging fluid from the injector assembly, ducting for conveying the fluid between the valve housing and the discharging means and a control valve movable to a first position in response to flow of the fluid in a first direction through the ducting to close the discharging means and return the fluid from the discharging means to the valve housing and movable to a second position in response to flow of the fluid in a second direction through the ducting to open the discharging means to allow at least some of the fluid conveyed to the discharging means to be discharged therefrom and to return any surplus fluid to the valve housing. Provided in the valve housing are inlet and outlet passages for conveying the fluid into and from the valve housing, and a change-over valve.
