    摘要： A fluid turbine comprises a turbine shroud, an ejector shroud, and a means for extracting energy from a fluid stream. The means for extracting energy is located in the annulus between the turbine shroud and the ejector shroud. High-energy fluid can flow through the turbine shroud to bypass the means for extracting energy. Energy is extracted from the fluid passing through the means to form a low-energy fluid stream. The high-energy fluid and the low-energy fluid can then be mixed. The turbine shroud and/or the ejector shroud has mixing lobes to increase the mixing of the two fluid streams.

    摘要： A shrouded wind turbine comprises a shroud disposed about an impeller. The impeller surrounds a nacelle body which is shaped to enhance smooth flow of wind through the impeller. Some embodiments include an inlet and an outlet in the nacelle body, allowing airflow through an interior cavity. Other nacelle bodies may be tapered, flared, include mixing lobes around a trailing edge, or may have other shapes that enhance fluid flow. Some nacelle bodies include an annular groove that promotes flow attachment. Maintaining airflow attachment to the nacelle body within the turbine increases the energy generation capacity of the wind turbine.

    摘要： A shrouded fluid turbine comprises an impeller and a turbine shroud surrounding the impeller. The inlet of the turbine shroud is flared. The shroud includes alternating inward and outward curving lobe segments along a trailing edge of the turbine shroud. The inward and outward curving lobe segments have exposed lateral surfaces, or in other words do not have sidewalls joining the inward and outward curving lobe segments. This allows for both transverse mixing and radial mixing of air flow through the turbine shroud with air flow passing along the exterior of the turbine shroud.

    摘要： A Controlled Unaided Surge and Purge Suppressor for firearms uses the blast and plume characteristics inherent to the ballistic discharge process to develop a new two-step controlled surge and purge system centered around advanced mixer-ejector concepts. The blast surge noise is reduced by controlling the flow expansion, and the flash effects are reduced by controlling inflow and outflow gas purges. This is a C-I-P application. In the preferred C-I-P embodiment, the blast surge is mitigated via a slotted mixer nozzle; a first expansion chamber; a generally “wagon-wheel” shaped blast baffle with a vent hole; a series of alternating baffles, with vent holes, strategically located along the suppressor's inner wall surface; a second expansion chamber; and an exit opening. This preferred C-I-P embodiment contains no “outside” vent holes (i.e., throughbores) which extend through the suppressor's outer or longitudinal wall. Instead of ingesting ambient air through such throughbores and mixing that air with the muzzle gases, as shown in the parent application, the preferred C-I-P embodiment ingests and mixes chamber gases and contaminants with the muzzle gases while allowing fluid flow through and out the suppressor. It too though can control or eliminate the Mach disk.

    摘要： A Powered Lower Bobbin Feed (“PLBF”) system is disclosed for improving the operation of deflector type rotary braiding machines, such as the Wardwell Rapid Braider. The PLBF eliminates or reduces the impulsive tension spikes set up by the deflection and feed process in current rotary braiding machines by uniquely controlling the lower bobbin filament feed. These tension spikes result from: the rapid rotational acceleration and deceleration required of the lower bobbin as a result of the feed process; the lever arm tension control and bobbin ratchet mechanism; and the shape of the filament deflector surface. Such failure limits the operating speed of rotary braiding machines, the minimum size of filament that can be braided effectively, or the ability to maintain the quality of the braid produced. By eliminating or reducing these spikes, the PLBF therefore can increase the working speed of circular braiding machines and improve the uniformity of braided filaments generated by such machines at a given speed. In the preferred embodiment, the PLBF comprises: a slip ring designed to provide power to the lower bobbins; a variable speed powered lower bobbin concept; a feedback control system for the bobbins to assure bobbin feed matches braid consumption; and an improved, more contoured, deflector surface to minimize feed tension spikes. The new contour can be created: by retrofitting existing deflectors with a spline; or, by making new deflectors that incorporate the overall contour of a retrofitted deflector.

    摘要： A fluid nozzle system (nicknamed the “RAP nozzle system”) is disclosed that combines a pulse flow device with a toroidal vortex generator to create a high momentum, self propelling jet for increasing long-range jet impact forces. In a preferred embodiment, the RAP nozzle system comprises a fluid switch, without any moving mechanical part, which takes continuous flow normally exited through a nozzle and breaks it into discrete patterns of pulsed flow. The unsteady characteristics of the pulsed flow are then used with either single-stage ejectors, multi-stage ejectors or other devices to increase the momentum and/or the lateral size of the individual pulses. These fluid pulses are then used to generate a jet with large scale, stable toroidal vortices which travel long distances, downstream of the ejector(s), and apply large forces at impact. Unlike the prior art, such toroidal vortices are stable, carry large flow momentum, and propel themselves through the air (or other fluid) at a speed approximately ¼ the pulsed velocity of the fluid used to generate the vortices. Furthermore, the toroidal vortices travel beyond the RAP nozzle system with minimal mixing and minimal losses. Tests conducted have demonstrated that these toroidal vortices travel up to 10 times the distance of current continuous flow jets and can deliver an order of magnitude larger force to move particles at large distances from the nozzle exit when compared to the same energy, continuous jet. The same toroidal vortices generate stirring mechanisms at impact which can be useful in many applications. The RAP nozzle system can significantly improve the performance of leaf blowers, shop air nozzles, and all other products that utilize jet impact forces for particle movement. The same RAP nozzle system concept can be used in a significant number of other applications where fluid pulsations could be beneficial. Fluid pulsations increase the force of a fluid jet by adding impulsive forces similar to a jack hammer. These unsteady forces can be quite large and are directly related to the velocity of the jet at impact. In an alternate embodiment, the RAP nozzle concept can also carry a secondary fluid over a large distance without mixing the secondary fluid with the ambient fluid. The secondary fluid is carried in the core of the toroidal vortices generated.
