The manifold tube is provided with a plurality of spray valve assemblies that are operated in a way so that the valves are turned on to permit spraying automatically as the spray bar manifold is extended laterally outwardly, and turn off the spray for the respective valve assembly as the manifold tube is retracted.

Abstract: An apparatus for dispensing viscous fluid material having one-piece nozzles which produce a supply of drops of fluid material. The nozzles each include a nozzle body having a first end and a dispensing end. A gas flow path through the nozzle body has an array of outlet sections which terminate at the dispensing end of the nozzle body. The inlet section of the gas flow path is a cylindrical bore which feeds a stream of gas to each of the outlet sections. A plurality of viscous fluid material passageways closely surround the outlet sections of the gas flow path. As a stream of material is discharged from each material passageway, the expansion of gas emerging from the gas outlet sections breaks up the flowing material, thereby applying the material in a spray of droplets even though both the gas flow and material flow are continuous. The first ends of nozzles are attached to an elongated dispensing bar of an applicator.

Abstract: A gated irrigation pipe is operated by a pneumatic control system which automatically opens and closes the gates. Each gate is slidable along the pipe surface and is coupled to a pair of parallel air conduits extending longitudinally along the pipe. The conduits are connected midway between their ends to a common movable pneumatic cylinder which receives therein a piston fixed to the exterior of the pipe. The conduits communicate with opposite ends of the cylinder, and serve as both an air line to the cylinder and an operating linkage which opens and closes the gates and which will not cause damage to the gates in response to differentials of expansion and contraction. A plurality of pipes thus equipped are serially connected to form an irrigation pipeline and the air conduits are interconnected at the pipe joints by flexible hose couplings which may be preset any time during each watering interval.

Abstract: A scarfing nozzle for producing a fin-free scarfing cut at least as wide as the width of the nozzle. The nozzle comprises an oxygen gas passage terminating in a nozzle discharge orifice characterized by having a central section and at least one end section. The central section is defined by parallel upper and lower edges and is adapted to discharge a sheet-like stream of cutting oxygen of uniform intensity across the metal body to be scarfed. The end section is defined by having at least one of its edges inclined such that the height of the end section is gradually reduced to a lesser value towards the side edge of the orifice but remaining greater than zero at the edge so as to diminish the intensity of the oxygen stream towards the edge of the orifice to the point where the flow of oxygen discharged at the edge is insufficient to scarf the workpiece but sufficient to produce a fin-free scarfing cut at least as wide as the width of said nozzle.
