A method and apparatus for use in the oil well industry for running in drilling / production liners and sub-sea casings down a borehole through drilling fluid on a drill pipe using a running tool with the benefits of surge pressure reduction are disclosed. In accordance with the present invention, a surge pressure reduction tool includes a diverter device having a housing with a set of flow holes formed therein and a sliding sleeve residing within the housing having a set of flow ports formed therein. By aligning the set of flow holes of the housing with the set of flow ports of the sleeve, the tool is set in a "surge pressure reduction" mode. By shifting, or axially indexing, the sleeve downward, the set of flow holes is blocked by the sleeve thus setting the tool in a "cementing" or "circulation" mode. This shifting or indexing is accomplished using an indexing mechanism. The indexing mechanism of the present invention includes a spring ring which is initially compressed and set in a circumferential groove formed around the top of the sleeve. As the sleeve is shifted downward from surge reduction mode to cementing / circulation mode, the spring ring decompresses radially outward to engage a circumferential groove formed in the housing. This effectively locks the sliding sleeve in the cementing / circulation mode. In accordance with the present invention, a surge pressure reduction tool further includes a volume compensation device which enables the diverter device to be shifted axially downward into the cementing / circulation mode even where the drilling / production liner or sub-sea casing is plugged with drill cuttings or downhole debris. In the cementing / circulation mode, a flow path is established for cement or drilling fluid to flow downward from the drill pipe, through the diverter device, volume compensation device, and running tool, and out into the borehole via the drilling / production liner or sub-sea casing. In the surge pressure reduction mode, an alternative flow path is established for drilling fluid to flow upward from the borehole into the drilling / production liner or sub-sea casing, through the running tool and volume compensation device, and into an annular space between the drill pipe and the borehole via the set of flow holes of the diverter device.

A plenum (210) in a gas turbine engine mid-frame section (200) comprises one or more annular flow splitters (240) spaced from an inboard annular wall (232) that partition air flow flowing from a compressor into two or more portions of flow having different vectors. This provides for an improved balancing between supplying air to compression chamber intakes more directly and to transitions to aid in convective cooling. When an annular diffuser (202) is spaced between the compressor and the plenum (210), the flow splitters (240) may provide an additional diffusion action. When no annular diffuser is so provided, the flow splitters (452, 454, 456) are effective to diffuse the air flow. Embodiments include those in which an annular diffuser (304) is relatively shorter and there is a longer axial expanse in the plenum (320) for flow splitters (350, 352, 354, 356).

A product-on-demand delivery system applies an agricultural product, such as seed, to a field. The system includes a frame that mounts a main hopper, a splitter fitting, a primary product hose, a secondary product hose, a primary application unit and a secondary application unit. The main hopper has an air nozzle wherein an air stream through the air nozzle entrains product within the air stream and delivers the air / product to the primary outlet hose. The splitter fitting has a splitter inlet flow-connected to the primary product hose and two splitter outlets flow-connected to the application units. The secondary application unit is coupled to the primary product supply hose by the secondary product hose connected at an outlet branch. The outlet branch is connected at an angle such that a product flow velocity vector in the primary product supply hose at the outlet branch is at an obtuse angle to a flow velocity vector of product flowing through the outlet branch. The outlet branch is oriented for a vertical upward flow of air and product.

A transition channel for a turbine unit with at least two components is configured as a flow channel from one component of a first pressure to a component of a second pressure. The transition channel has support ribs, extending between envelope surfaces of the transition channel and having a profile that is configured for the deflecting of a flow from an inlet cross section to an outlet cross section of the transition channel. Flow splitter blades are arranged between the support ribs, having a smaller relative profile thickness than the support ribs and / or a shorter axial design depth or profile chord length than the support ribs. Thanks to the integration of the slim and / or short flow splitter blades (tandem blades), it is possible to largely dissipate parasite secondary flows.

A multi-dimensional liquid analysis system includes a flow splitter for separating mobile phase outflow from a first dimension liquid analysis system into first and second liquid split outlet flows. Volumetric flow rate control of the split outlet flows is provided by a flow control pump which withdraws one of the split outlet flows from the flow splitter at a controlled withdrawal flow rate to define the other split outlet flow rate as the difference between the outflow rate from the first dimension system and the withdrawal flow rate. In this manner, accurate and consistent flow division can be accomplished, which is particularly useful for multi-dimensional liquid analysis.

An electronic system includes a chassis, an air flow distribution assembly having a first set of baffles disposed within an intake volume of the chassis and a second set of baffles disposed in proximity to an air outlet of the chassis. The first set of baffles is configured to turn the flow of an air stream approximately 90 degrees, relative to an inlet flow direction of the air stream, toward circuit boards disposed within the chassis. The second set of baffles is configured as a flow splitter that receives the air stream from the circuit boards and partitions the air stream into separate portions prior to the air stream exiting via the air outlet. The use of both the first and second set of baffles redirects and distributes the air stream, flowing into the air inlet, in a substantially even manner across the circuit board component mounting surfaces of the circuit boards disposed within the system.

A solid particle counting system for measuring solid particle number concentrations from engine or vehicle exhausts in real-time includes a diluter arrangement, a particle counter, and a flow splitter. The diluter arrangement mixes the dilution gas with flowing sample gases. The flow splitter receives the output flow from the diluter arrangement, provides a portion of this flow to the particle counter, and provides a by-pass flow that is received by a vacuum pump. A second flow route to the particle counter includes a valve arranged such that opening the valve during the starting of the vacuum pump reduces a pressure pulse at the particle counter caused by the starting of the vacuum pump, thereby avoiding work fluid backflow from the particle counter prior to the vacuum pump stabilizing.

An adjustable device installed at the inlet of conventional junctions / splitters (116) for on-line control of the distribution of coal among the outlet pipes is herein disclosed. The device includes a plurality of wake inducing airfoils (60) each positioned upstream of a plurality of flow channels in the riffler (50) for directing coal flow to the outlet pipes. Each wake-inducing airfoil has a cross-section defined by a width W that varies along its length H for creating upstream turbulence, and a particle wake that preferentially diverts the coal flow to one of the outlet pipes at the splitter junction without affecting primary air flow. For example, each wake inducing airfoil may comprise a rounded convex edge leading to straight tapered sides. The surfaces of the sides may be roughened or textured (63) for promoting turbulent boundary layers. In addition, conventional fixed or variable orifices may be used in combination with the wake inducing airfoils for balancing primary air flow rates. The device allows fine-adjustment control of coal flow rates when used in combination with the slotted riffler, yet it has negligible effect on the distribution of primary air, resulting in closely balanced coal flow, reduced pollutant emissions and improved combustion efficiency.

An adjustable device installed at the inlet of conventional junctions / splitters (116) for on-line control of the distribution of coal among the outlet pipes is herein disclosed. The device includes a plurality of flow control elements (60) each positioned upstream of a plurality of flow channels in the riffler (50) for directing coal flow to the outlet pipes. Each flow control element preferably comprises a rounded convex edge leading to straight tapered sides (FIG. 9). The surfaces of the sides may be roughened or textured (63) for promoting turbulent boundary layers (FIG. 9). In addition, conventional fixed or variable orifices may be used in combination with the flow control elements for balancing primary air flow rates. The device allows fine-adjustment control of coal flow rates when used in combination with the slotted riffler, yet it has negligible effect on the distribution of primary air. The combination of the riffler assembly and the coal flow control elements (60) results in closely balanced coal flow. Balanced coal flow is imperative to the optimization of the operation of pulverized coal boiler systems (i.e. reduced pollutant emissions, improved combustion efficiency).
