  • Patent number: 9404339
    Abstract: Fluid flow influencer devices in chambers subsequent to vortex assemblies are described. A flow-affecting device can move from a first position to a second position based on a flow path of fluid flowing from the vortex assembly to the chamber. The flow path may depend on an amount of rotation of the fluid from the vortex assembly. The flow-affecting device in the first position can substantially allow fluid to flow through a chamber exit opening. The flow-affecting device in the second position can substantially restrict fluid from flowing through the chamber exit opening.

The characteristics of the pressure waves generated by the device are controlled by the growth and decay of vortices in the vortex chamber(s) of a flow path. The flow path includes a switch, such as a bi-stable fluidic switch, for reversing the direction of the flow in the vortex chamber. The flow path may include multiple vortex chambers, and the device may include multiple flow paths. A hardened insert in the outlet of the vortex chamber resists erosion. This device generates backpressures of short duration and slower frequencies approaching the resonant frequency of the drill string, which maximizes axial motion in the drill sting and weight on the bit. Additionally, fluid pulses produced by the tool enhance debris removal ahead of the bit.

    Abstract: A system and method for conveying flowable material through a conduit that creates a strong laminar flow of the material surrounded by a boundary layer flow of the same or a different flowable material, such that long transport distances through dramatic elevation and directional changes can be achieved. Some embodiments of the system include a blower assembly, an inlet conduit, an outlet conduit and a mixing chamber, wherein the mixing chamber includes an outer barrel, an inner barrel and an accelerating chamber. Low pressure air is supplied to the system by the blower assembly and mixed with particulate material. The air/material mixture is transported through the mixing chamber into the accelerating chamber and through the outlet conduit. In other embodiments, the particulate material is mixed with the air in the accelerating chamber.

  • Patent number: 7556785
    Abstract: Phosphine gas is generated by agitating a reaction mixture of a metal phosphide and water with agitation air in a reaction pot of a phosphine gas generator. The resulting phosphine gas is then diluted with dilution air to produce a fumigant phosphine gas which is directly delivered to a commodity for fumigation. The reaction pot does not have any rotating means such as agitators, rotors, or stirrers. The generator provides on-site generation of phosphine gas in a rapid manner improving the fumigation efficiency for a commodity, such as grain, preferably contained within a storage structures, such as a grain silo. The generator has a built in deactivation system for the unused metal phosphide and phosphine gas.

  • Patent number: 7478767
    Abstract: An apparatus for regulating fluid flow through a spray nozzle comprising a circular chamber (1) defined by spaced apart end walls, a peripheral side wall (3), a central axis, and a first inlet at or near the peripheral side wall (3) to allow a flow of fluid to enter said chamber (1) tangential to the peripheral side wall (3), and an outlet (4) exiting through one of the end walls. In use a flow of fluid entering through the first inlet has a primary lower layer (16) that follows a first circular flow path which forms a vortex commencing at the peripheral side wall (3) and increases in velocity and pressure towards the outlet and at least one secondary upper layer (17) that substantially follows a second flow path radially inwardly towards the central axis. The primary lower layer (16) and the secondary upper layer (17) interact and support each other over at least a portion of flow between the inlet and outlet (4).

    Abstract: The inlet device has a horn-shaped passage piece at a peripheral wall of a column that feeds a fluid tangentially into the column so that the fluid enters into a vortex flow that rotates around an axis adjacent to a central axis of the column. A middle zone and discharge zone of the passage piece are made in the manner of a diffuser and abut the peripheral wall to extends over less than one half of the wall. A discharge zone of the passage piece through which flow takes place presets a middle flow direction of the fluid which extends along the peripheral wall and is inclined against the main direction.

  • Patent number: 7011101
    Abstract: A valve system (10) controls the fluid flow between an inlet (12) and an outlet (14). The system (10) splits the flow into two parallel flow ducts (15, 16) and recombines the flows through opposed tangential inlets (18) and (19) of a fluidic vortex valve (20) which has an axial outlet (22). An adjustable valve (24) controls the flow through one of the parallel flow ducts (15), controlling the strength of the vortex generated within the vortex valve (20). Hence a small valve (24) can control and adjust the flows in both ducts (15 and 16).
