Acoustic energy is used to control motion in a fluid. According to one embodiment, the invention directs acoustic energy at selected naturally occurring nucleation features to control motion in the fluid. In another embodiment, the invention provides focussed or unfocussed acoustic energy to selectively placed nucleation features to control fluid motion. According to one embodiment, the invention includes an acoustic source, a controller for controlling operation of the acoustic source, and one or more nucleation features located proximate to or in the fluid to be controlled.

Improvements are provided for a syringe-to-syringe mixing system to improve the mixing characteristics of the system. In one embodiment, a mixing apparatus includes opposite fittings for mounting to a pair of syringes. The mixing apparatus defines a fluid passageway therethrough and includes a flow modifying element disposed within the passageway. The flow modifying element is configured to increase the flow velocity, disrupt the fluid flow or introduce turbulence into the fluid flow between the two syringes. In another embodiment, a nozzle element is disposed within the tip of the syringe, the element configured to increase the fluid flow therethrough. The nozzle element can be a nozzle insert removably mounted within the tip, or an integrally formed nozzle within the tip.

Smooth, preferably variable-sweep fluid collection device surfaces disposed into opposition with wind, river, surf, ocean or tidal currents generate enhanced velocity fluid flows at length driven into onboard work-extracting disc turbines at advantageous angles of attack. Keyed to shafts turning freely through optionally extendable volutes, disc turbines comprising a dense population of smooth, axially fixed or adjustably spaced discs conducting preferably laminar flow between adjacent elements develop significant torque through boundary layer adhesion and viscous shear-stress between fluid layers. Exhaust of disc turbine throughput into divergent channels drafting into external currents of initially higher than ambient velocity and lower pressure may reduce turbine discharge backpressure, rapidly clear system throughput, and allow normally disadvantageous drag to be utilized to develop greater work generation. Gainfully turning with, instead of at odds to natural or anthropogenic currents provided, disc turbines utilized as disclosed may provide unprecedented renewable energy from fluids in motion.

New methods and systems for subterranean fracturing for hydrocarbon wells. A plan of the fracture propagation and in-fracture proppant distribution is used with a real-time model of the status of the fracture dimensions and in-fracture proppant concentration to automatically control flow rates and properties of a fracturing fluid flow stream being used to induce and prop the fracture. Real-time measurements of the status of the fracture are made using surface and/or down-hole sensors. Real-time control over the flow rate and properties of a fracturing fluid flow stream are made by manipulating the fracturing fluid supply equipment. Real-time modifications of the fracturing model are made by comparing fracture sensor measurements of actual fracture dimensions to the predicted dimensions, and then adjusting the model for inaccuracies. Real-time updates to the fracturing plan are made by comparing actual fracture and propping results to desired results, and then adjusting to achieve optimal results.

An integrated material transfer and dispensing system for storing, transferring and dispensing materials, such as fluids, and liquids, for example, liquid applied sound deadener (LASD). The system includes at least one vessel having a force transfer device. Each vessel may be removably enclosed in cabinet to form an automated station. Each vessel may be configured with a data logger, cleanout port, a sample valve at least one sight window and an access port for introducing a compound such as a biocide. Each vessel may be configured with instruments including sensors for measuring process variables, such as material volume, level, temperature, pressure and flow. The system may further include a metering device system and a robotic material dispenser system without a pump interface. The robotic system may further include a computer control system connected to flow and pressure sensors. The system may directly feed an applicator without an intervening pump.

In thermal pulse flow measurements a relatively small bolus of flowing fluid is heated or cooled and the time required for the bolus to move downstream a known distance is measured. In many fluids, changing the temperature changes the acoustic transmission properties of the bolus from those of the rest of the fluid, so the bolus can be detected when it intersects an acoustic beam. The use of an acoustic beam or beams, which are usually defined between acoustic transmitting receiving transducers, typically provides a high frequency carrier which is modulated by the change in acoustic properties of the bolus when it passes between the two transducers. When compared to conventional thermal measurements, this acoustic approach provides faster response times and can thus be used for measuring higher flow rates.

A pleated panel fluid filter filters fluid flowing along an axial flow direction and includes angled panels and/or progressively increasing flow channel width and/or skewed panel projections and/or flattened pleat tip bend lines.

A transparent illuminated infusion cannula is provided for illuminating an area during eye surgery. An optical fiber may be spaced a certain distance away from the cannula such that fluid flow around the distal end of the fiber and into the transparent cannula may occur with a much higher flow rate than what had previously been possible. The fiber cannula airspace may be optimized so that the cross-sectional area of the fluid conduit remains substantially constant in order to achieve a best compromise between high light transmittance and high fluid flow rate.

The pollution control system includes a controller coupled to a sensor monitoring an operational characteristic of a combustion engine, such as engine RPM. A PCV valve having an inlet and an outlet is adapted to vent blow-by gas out from the combustion engine. A fluid regulator associated with the PCV valve and responsive to the controller selectively modulates engine vacuum pressure to adjustably increase or decrease a fluid flow rate of blow-by gas venting from the combustion engine. The controller selectively adjustably positions the fluid regulator to vary the degree of vacuum pressure to optimize the recycling of blow-by gases.

An implantable medical assembly includes a cover having a porous chamber. Enclosed within the chamber is a medical device through which aqueous body fluid flows from an outlet of the device into the chamber. The chamber is formed at least in part from a porous material that promotes vascularization and inhibits fibrotic encapsulation upon implantation and that allows aqueous body fluid in the chamber to flow through the porous material into body tissue in which the assembly is implanted. The chamber has a pair of walls that are spaced apart at a first portion of the chamber at or near the outlet and converge at a second portion of the chamber downstream of the outlet.

The present invention relates to a fluid treatment system comprising: an inlet; an outlet; and a fluid treatment zone disposed between the inlet and the outlet. The fluid treatment zone has disposed therein: (i) an elongate first radiation source assembly having a first longitudinal axis, and (ii) an elongate second radiation source assembly having a second longitudinal axis. The first longitudinal axis and the second longitudinal axis are non-parallel to each other and to a direction of fluid flow through the fluid treatment zone. The present fluid treatment system has a number of advantages including: it can treat large volumes of fluid (e.g., wastewater, drinking water or the like); it requires a relatively small “footprint”; it results in a relatively lower coefficient of drag resulting in an improved hydraulic pressure loss/gradient over the length of the fluid treatment system; and it results in relatively lower (or no) forced oscillation of the radiation sources thereby obviating or mitigating of breakage of the radiation source and/or protective sleeve (if present). Other advantages are discussed in the specification.

Two-way, three-position and one-way, two-position slit valves in cardiovascular access catheters with closed distal ends have slit geometries configured to overcome adhesion between opposed abutting slit faces, when pressure differentials are applied between the interior and the exterior of the catheter. Portions of the slit are oriented at a non-zero angle relative to the longitudinal axis of the catheter causing shear forces to be generated in abutting slit faces. Shear forces arise from tangential, radial, or longitudinal stresses generated in the catheter body. Slit geometries are planar or curved or include multiple end-to-end connected slit subsections. If a slit partially circumscribes a portion of the adjacent outer wall of the catheter body, restraint to outward and inward movement on that portion is reduced. Slit valves are configured to open inwardly to aspirate fluids, to open outwardly to infuse fluids, or both.

A bottom hole assembly (BHA), adapted to be positioned in a casing and to isolate a portion of a wellbore, which includes a packer assembly with a first sealing element extending between first and second portions of the packer assembly. A method of setting a BHA in a casing which includes increasing a BHA pressure to activate an anchor assembly, applying a mechanical force to mechanically deform a first sealing element to thereby establish an initial seal between the first sealing element and an interior surface of the casing, and increasing a pressure in a space between the BHA and the casing and in a cavity within the BHA to increase a differential pressure across the first sealing element and thereby establish a pressure-energized seal between the first sealing element and the interior surface of the casing.

A material transfer system for storing, transferring and dispensing viscous material, such as fluids and liquids, includes a material containment vessel with an upper region incorporating a motive force and a bottom region with a material ingress and egress opening. A diconical or other shaped force transfer device is located in the material containment area. The force transfer device is an energy transducer when the material containment is filled with highly viscous materials, such as adhesives, sealants, mastics or lubricating greases. The force transfer device serves as an integral part of a level indicator for both viscous fluids and lower viscosity liquids. The viscous material itself forms a seal between the interface region of the force transfer device and the inside wall of the fluid vessel. Vertical stabilizing elements may extend outward from the force transfer device.

An artificial baby-feeding nipple has one or more openings formed therein for conveying fluids through the nipple. The nipple is configured and formed of a material which permits changeable flow rates in response to changing suckling conditions.
