  • Patent number: 11207656
    Abstract: A particle control method configured prevent an extremely small quantity of particles descending on a stream of a laminar flow in a clean zone through which the laminar flow flows (as in a RABS or isolator device) from descending to a specific position or to guide the particles so as to have them descend to a specific position by controlling movement of the particles. [Solution] A particle descent position is separated away from a board surface of the oscillation board by using an acoustic radiation pressure generated by prompting ultrasonic vibration of the oscillation board disposed with a board surface substantially in parallel with a flow direction of the laminar flow. Moreover, by using a node of a standing wave field generated by prompting the ultrasonic vibration of two oscillation boards disposed with the board surfaces faced with each other, the particle is guided to a direction of a node of a standing wave field.

  • Patent number: 11202981
    Abstract: A device separates particles, such as oil particles, from a gas flow, from a blow-by gas of a crankcase ventilation, in an internal combustion engine. The device includes a valve seat, which defines at least one flow passage opening and through which the gas flow at least partially flows in a main flow direction, and a movable valve element, which can be adjusted relative to the valve seat such that flow guide surfaces of the valve seat and the valve element deflect the gas flow in such a way that particles separate from the gas flow due to the impact of the particles on the flow guide surfaces. At least one flow guide surface of the valve seat or the valve element has at least one turbine blade-like guide projection or at least one turbine blade-like guide depression in order to transform the gas flow into a swirling flow.

  • Patent number: 11192067
    Abstract: This invention relates to a process and apparatus for growing agricultural products with a reduced abundance of radioactive carbon-14 (14C) by employing centrifugal separation of atmospheric gases to selectively remove carbon dioxide (CO2) with 14C. Agricultural products with reduced 14C content can be grown in controlled environments with filtered atmospheric gases for the benefit of reducing harmful damage to human DNA that is unavoidable with our current food chain, due to the natural abundance of 14C in atmospheric gases. Bilateral and unilateral compression helikon vortex apparatus provide efficient and economical removal of CO2 with 14C from atmospheric gases with a single filtration pass, which is ideally suited for large scale agricultural production.

  • Patent number: 11173440
    Abstract: Various rotating coalescer elements are described. The rotating coalescer elements include various arrangements of stacked separator discs or cones. In some arrangements, the described rotating coalescer elements include a combination of stacked separator discs or cones and filter media. In some arrangements, the stacked separator discs are designed to provide the largest possible amount of radial-projected separation surface area in a given rotating cylindrical volume, where flow to be cleaned is passing radially (outwardly or inwardly) through the rotating coalescer element. In some arrangements, this is achieved by stacking non-conical separating plates containing various area-maximizing features (e.g., spiral ribs, axial cylinders, spiral grooves, or spiral “V” shapes).
