  • Patent number: 10480668
    Abstract: A device for restricting liquid backflow through an overhead line on a tank and a method of using the device are provided. The device has a tubular housing with spaced internal baffle plates. The device is secured in place in the interior of an overhead pipe on the top of a tank on a tank truck or other vehicle used for transporting bulk liquid cargo. The device prevents liquid backflow from entering overhead piping due to sloshing action of the liquid during transport. The device allows air to flow through the device so that air may be supplied to the tank, as well as vented from the tank, through the device.

  • Publication number: 20140345732
    Abstract: A modular hydraulic hammer reduction system for railroad tank cars includes tubular hydraulic hammer reduction devices which include means to connect the tubular devices to flanges other than by welding or being cast together. For example, the tubular devices can be press fit into the flanges, or the tubular devices can be connected to the flanges with snap rings (preferably spiral-lock snap rings), or even more preferably the tubular devices can be press fit into the flanges and the tubular devices can be connected to the flanges with snap rings (preferably spiral-lock snap rings). The advantage of this modular construction is that one can manufacture multiple tubular devices and multiple flanges of each type, and connect the flanges to the tubular devices on an as-needed basis.

  • Publication number: 20140264107
    Abstract: A fluid pressure reduction device includes a radial and axial fluid flow path in stacked disks. The stacked disks form a fluid flow path including at least two pressure reduction stages, a first pressure reduction stage being oriented so that the fluid flowpath is directed radially outward and a second pressure reduction stage being oriented so that the fluid flowpath is directed radially inward.

  • Publication number: 20140251442
    Abstract: A device and a method for reducing the pressure of a fluid containing granules. The device comprises a free space devoid of moving rotor blades and a housing with an inlet and an outlet. The shape of the wall within the housing and of the free space therein applies a centripetal flow component to the fluid containing the granules flowing therethrough. The pressure of the fluid containing the granules is decreased after the flow has passed through the device. The device and method further and impart a rotational motion to the fluid containing the granules in the area of the outlet, which is generally located in the central area of the free space.

  • Patent number: 8783286
    Abstract: Structures and methods are provided for improving the distribution of fluids between exit flows from a split junction, such as a tee-junction. The improved distribution of fluids can result in a more equal distribution of both gases and liquids between the exits of the junction. The improvement can be provided by using a baffle structure, such as an annular baffle structure, upstream from the desired junction. The baffle structures can improve the distribution of fluids in the exit flows in various manners, such as by reducing the amount of vorticity or “swirl” in the input flow to the junction or by reducing the separation of gases from liquids within a flow.

  • Patent number: 8783296
    Abstract: A water-saving antiblocking anti-splash waterfall water curtain head core comprises a housing having an upper portion internally enlarged and a flow leading mouth set inside the housing; a block is set under the flow leading mouth, and there are spaces between the upper surface of the block and the exit of the flow leading mouth; the upper surface of the block is fixedly connected with a support rod going through the flow leading mouth; a flow leading bracket with through holes is fixedly connected to the internally enlarged upper portion and to a top of the support rod; the flow leading mouth is such sized to anti-block. During operation, the surface of the block equally blocks water flow and accordingly forms hollow film-like water curtain.

  • Patent number: 8753579
    Abstract: The photoreactor comprises a tube bundle (10) made up of numerous capillary tubes (11) through which a reaction medium flows. The tubes (11) are transparent. Solar radiation or artificial radiation acts upon the reaction medium for effecting a photochemical or photobiological treatment. The inlet chamber (12) connected with the tube bundle (10) comprises a flow distributor (16) which distributes the reaction medium from the fluid inlet (15) to the tubes (11). The flow distributor (16) allows for a smaller volume of the inlet chamber (12). The reactor volume, which is not irradiated, is thus reduced, and the efficiency of the rector is enhanced.

  • Patent number: 8733403
    Abstract: Water economizer device applicable to general fittings intended for its installation in hot and cold water feeding pipes and especially between the water supply pipe for shower artifacts whereby water consumption is reduced and the same water effect and the same sensation and result of conventional fittings is maintained. It is characterized by a coupled conduit between the water supply pipe and the water outflow artifact, within which a set of items are placed successively and operatively cooperatives between each other and which includes a piece that reduces water inflow, a piece that generates water turbulence and a piece that recovers outflow direction.

  • Publication number: 20140069541
    Abstract: Various systems and apparatuses are provided for a fluid transfer system for an engine. In one example, a system includes a first turbine having an exit for discharging a main fluid flow and a second turbine having an inlet for receiving at least a portion of the main fluid flow. A main conduit fluidically couples the exit of the first turbine to the inlet of the second turbine. A transition conduit is coupled with the main conduit and includes a volute passageway curving around the main conduit. The volute passageway includes a slot that follows a route around the curving volute passageway and opens into an interior of the main conduit. The slot is defined at least in part by a lip and establishes a path for either a secondary fluid flow to enter the main conduit or a portion of a main fluid flow to exit the main conduit.

  • Patent number: 8646535
    Abstract: An inflow control device may include flow control elements along a flow path. The flow control elements may change the inertial direction of the fluid flowing in the flow path. The change in inertial direction occurs at junctures along the flow path. The flow control elements may also be configured to form segmented pressure drops across the flow path. The segmented pressure drops may include a first pressure drop segment and a second pressure drop segment that is different from the first pressure drop segment. The pressure drop segments may be generated by a passage, an orifice or a slot. In embodiments, the plurality of flow control elements may separate the fluid into at least two flow paths. The flow control elements may also be configured to cause an increase in a pressure drop in the flow path as a concentration of water increases in the fluid.
