  • Patent number: 11035480
    Abstract: A sequencing manifold for the purpose of supplying control and supply services of pre-determined temporal sequences to fluid processing assemblies is provided. The functioning of this sequencing manifold requires that translation be applied to the sequencing ports. Actuator mechanisms may supply such translation as either continuous motion or as a series of stepwise motions. Actuator mechanism can be obtained that rely on only mechanical means without the need for a source of electricity. With such actuators, it becomes feasible to conduct the operations of fluid processing assemblies in remote and primitive locations that lack a source of electricity. One skilled in the mechanical arts can provide various actuator mechanisms to meet these requirements.

  • Patent number: 10844887
    Abstract: Fluid flow enhancing devices disclosed herein are adapted to enhance flow of fluid through subsurface watershed conduits, for example, culverts, drainpipe and the like. Such fluid flow enhancing devices advantageously enhance watershed runoff functionality in subsurface watershed conduits by altering watershed flow from a parabolic flow pattern to a rotational flow pattern while still accommodating fish passage requirements. This change in flow pattern beneficially provides turbulence that disrupts and flushes debris out of the subsurface watershed conduits. This disruption and flushing establishes a passive cleaning functionality within the subsurface watershed conduits that serves to clean the subsurface watershed conduits after suitable upstream water delivery event (e.g., heavy rain, controlled water release, etc.).

  • Patent number: 9140134
    Abstract: A guide vane of a turbo-compressor has variable turbine geometry, in particular for a motor vehicle. The guide vane has a profile with a lower side, an upper side and a front edge. The guide vane is characterized by a nose which extends along the front edge of the vane, from the front edge of the vane to the upper side of the vane and forms a low pressure on the upper side of the vane when waste gas impacts the guide vane. A guide vane configuration, a turbo-compressor, a motor vehicle and a method for operating this type of turbo-compressor are further disclosed.

  • Patent number: 9114375
    Abstract: Some embodiments of the present invention provide components for a serpentine fluid reactor which is optimized for one or more objective functions of interest such as pressure drop, erosion rate, fouling, coke deposition and operating costs. The components are designed by computer modeling the components individually and collectively in which the cross section of flow path is substantially circular under industrial conditions to validate the model design and its operation. Then iteratively the component designs are deformed and the operation of the deformed part(s) is modeled and compared to values obtained with other deformed models until the value of the objective function is optimized (e.g. at an extreme) or the change in the objective function is approaching zero.

  • Patent number: 9046115
    Abstract: An eddy-current-minimizing flow plug has open flow channels formed between the plug's inlet and outlet. Each open flow channel includes (i) a first portion that originates at the inlet face and converges to a location within the plug that is downstream of the inlet, and (ii) a second portion that originates within the plug and diverges to the outlet. The diverging second portion is approximately twice the length of the converging first portion. The plug is devoid of planar surface regions at its inlet and outlet, and in fluid flow planes of the plug that are perpendicular to the given direction of a fluid flowing therethrough.

  • Patent number: 8974200
    Abstract: An apparatus and method are disclosed for inducing fluid flow. A fluid flow apparatus includes a directional membrane, a directional flow mechanism, and an oscillation module. The directional membrane allows a fluid to pass through the directional membrane in a first direction and resists fluid passing through the directional membrane in a second direction, the first direction substantially opposite the second direction. The directional flow mechanism allows a fluid to flow in a third direction and resists fluid flow in a fourth direction, the third direction substantially opposite the fourth direction. The oscillation module induces an oscillation in the directional membrane, wherein the oscillation of the directional membrane induces a flow of the fluid through the directional membrane in the first direction.

  • Patent number: 8973616
    Abstract: A pipe, such as a liner for repairing a failing culvert, comprises a continuous wall defining an inner wall surface and an exterior wall surface. The pipe further defines a central fluid passageway extending from an inlet end to an outlet end. The inner wall surface of the pipe defines a waveform-like geometry near the inlet end, said waveform-like geometry including an initial curvature beginning at the inlet end of the pipe and continuing until reaching a predetermined location where an inner diameter of the pipe is minimized, the curvature then continuing with the inner diameter increasing again to a second predetermined location, before the inner diameter again decreases to a third predetermined location and then remains substantially constant along the remaining length of the pipe, thus creating an annular recess in the inner wall surface of the pipe.
