Abstract: In the prior art, there is U.S. Pat. No. 3,386,611 which discloses a uni-directionally controlled hydraulically-actuatable center-pivot irrigation apparatus, having strategically located three-way valves. The instant invention discloses a dual-directionally controlled hydraulically-actuatable center-pivot irrigation apparatus having strategically located four-way valves, a dual-directional-valve, and other ancillary features interposed along hydraulic-control lines for the center-pivot irrigation apparatus. Accordingly, there are ancillary means for controlling the angular directional movement of the irrigation apparatus through a dual-directional-valve conveniently located at the center of a field to be irrigated by the apparatus.

Abstract: The integrated modular spraying system is suitable for applying chemicals, including liquids and dry flowables, to various remote locations. The system includes an integrated modular tank which is preferably rotomolded from thermoplastic. A well is formed in the side of the tank and is further defined by two opposing buttresses which receive and support a freely rotating hose spool. A pump is located in a recess in the tank for pumping chemicals from the tank through the flexible hose. The hose can be peeled off from the hose spool for a substantial length to enable an operator to spray a chemical at locations remote from the integrated modular spray apparatus. After application of the chemical is complete, the hose spool can be rotated to rewind the flexible hose about the spool. In an alternative embodiment, the apparatus is suitable for applying dry flowables, including various insecticidal dusts and powders, using an air pump instead of a liquid pump.

Abstract: A plural component external mix air-assisted/airless spray gun has an airless tip from which resin is emitted in a fan-shaped spray and an injector nozzle for directing an unatomized stream of catalyst into the resin adjacent to the airless tip. The catalyst injector nozzle is built into an ear of an air cap and the air cap is keyed to the airless tip to guarantee the positional relationship between the injector nozzle and the airless tip. Injecting a stream of unatomized catalyst into the resin stream immediately downstream from the airless tip provides thorough mixing of the catalyst into the resin, increased utilization of the catalyst and decreased emissions of catalyst fumes.

Abstract: The invention relates to a flexible spray bottle (10) for nasal spray, onto the bottle neck (14) of which a spray cap (12) is placed. The top wall (17) of the spray cap (12) contains a spray opening (20) and, on the underside, a connection piece (18) for a dip tube (21). A mixing-air passage (30, 31) extends between the connection piece (18) and the dip tube (21), with the result that a liquid/air mixture leaves the spray opening (20). An annular flange (15) of the spray cap (12) contains an air-admitting passage (23) which extends radially in the flange and is angled inside the spray cap towards the interior of the bottle (10). The angled part contains an air-admitting valve with a valve body (28) which is pressed against a valve seat (27) in the case of positive pressure in the container and seals off the air-admitting passage (23). In the open position of the air-admitting valve, the valve body (28) rests on supporting arms (29) which make possible the passage of air through the air-admitting passage (23).

Abstract: An ultrasonic wave nebulizer for converting water or liquid to mist has a disc-shaped piezoelectric vibrator (1) which has a pair of surfaces one of which is defined as an operation surface. A mesh (3) is located close to said operation surface so that a gap (G) or a thin water or liquid film is defined between the mesh and the operation surface. The gap spacing is smaller than the diameter of water drop which is composed by surface tension of water when no mesh were located. Upon excitation of the vibrator with high frequency, the water film is converted to mist. Fresh water is supplied in said gap spacing through capillarity. The exciting frequency is almost the same as the resonant frequency of the vibrator. The present nebulizer is useful for a small atomizer which operates with small power consumption.

Abstract: A spraying device having an automatic flushing system. A pressurized tank of formulation is mounted on a wheeled frame and connected to a plurality of nozzles via a three-way valve. The valve is further connected to a container of flushing medium. A programmable controller operates the three-way valve to periodically interrupt formulation flow and allow flushing medium flow through the conduits and nozzles to prevent clogging thereof. A pair of liquid sensors in the formulation conduit detect cessation of formulation flow triggering a timer operating the three-way valve causing flow of flushing medium upon completion of the formulation application. The formulation tank includes a vertically adjustable outlet tube controlling the amount of applied formulation. A centrifugal fan blows air past the nozzles carrying the emitted droplets into the atmosphere.

The purging rod which has a main body of a diameter slightly less than that of the mixing chamber, and a forward end that defines a probe of a diameter that is slightly less than the dimension of the minor axis of an elongate orifice of the airless tip. During spraying, the purging rod is retracted rearwardly of the mixing chamber and of coreactive fluid inlets to the chamber.

Following assembly, a solvent is introduced into the injector to dissolve the shim, which is constructed of a material readily dissolvable in the desired solvent, to define the working air gap and, therefore, the static flow through the injector.

Abstract: A one-piece nozzle adapted for use within an adhesive dispenser includes a nozzle body formed with a throughbore having a discharge outlet within a nozzle tip portion which emits a bead of adhesive. A nozzle cap mounts the nozzle body to the adhesive dispenser such that an adhesive passageway within the dispenser communicates with the throughbore in the nozzle body and a plunger valve associated with the adhesive dispenser extends into the nozzle body in position to engage a seat formed at the nozzle tip. A number of air jet bores are drilled in the nozzle body, each communicating with an air passage formed between an outer surface of the nozzle body and an inner surface of the nozzle cap, which discharge jets of air into contact with the adhesive bead producing an elongated adhesive fiber deposited in a spiral pattern onto a substrate.

Abstract: A sealing gun (31) of a sealant application unit, which controls the flow of the sealant in accordance with the value of an input signal, is attached to the end of a robot arm. The value of a signal applied to the sealant application unit (30) is controlled in association with acceleration/deceleration control of the moving speed of the sealing gun. The moving speed (TSA) of the sealing gun and the flow (SC) of the sealant discharged from the sealing gun are in direct proportion; therefore, the bead width becomes uniform independently of the moving speed (TSA) of the sealing gun.
