摘要： 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.

摘要： In order to control bubble removal or mixing in a flow channel, bubble transfer between flow channels (1, 2) is controlled by disposing first flow channel (1) for flow of a first fluid of liquid or gas and second flow channel (2) for flow of a second fluid of liquid with, interposed therebetween, gas exchange unit (5) through which while no liquid can pass, a gas component can be transferred, and by providing a pressure difference between the flow channels (1, 2) with the gas exchange unit (5). By rendering the pressure of the second flow channel (2) higher than that of the first flow channel (1), any bubble transfer from the first fluid to the second fluid is prevented, or bubbles within the second fluid are transferred into the first fluid to thereby attain deaeration.

摘要： The invention provides a method of operating a cascade gas separation process and a gas separation cascade (10) useful for uranium refining and employing a carrier gas. The method and cascade of the invention involve arranging relative gas flow rates between at least some modules (12) in the cascade so that the relative proportions of process gas leaving and entering each of said modules are such that there is a substantially constant molar flow rate of gas in each direction along the cascade through said modules. The proportion of carrier gas relative to process gas increased in opposite directions from the feed (14) to the opposite ends (20, 22) of the cascade and the modules through which the constant molar flow rate takes place have substantially the same size, capacity and construction.

摘要： An apparatus for isotope separation by the separating-nozzle process has a horizontally disposed cylindrical housing in which a multistage radial compressor is received, the compressor being surrounded by the cooling units and separating-nozzle units of the various stages connected in cascade. The system is extremely compact and has high efficiency because it is free from excessively long flow paths.

摘要： Turbo-separative methods and apparatus for separation of mixtures of gaseous materials having different molecular weights, particularly gaseous isotope mixtures such as mixtures of UF.sub.6, in which differential sedimentation velocities of the components to be separated are established in a laminar boundary layer of the gas adjacent a hydraulically smooth, porous blade surface, and in which a predetermined amount of the boundary layer flow is conducted through the porous surface to stabilize the boundary layer and to provide a higher density gas fraction. The velocity of the gas conducted through the porous blade surface should not exceed the sedimentation velocity of the gas species to be separated.

摘要： Method and apparatus for separating isotopes in an isotopic mixture of atoms or molecules by increasing the mass differential among isotopic species. The mixture containing a particular isotope is selectively irradiated so as to selectively excite the isotope. This preferentially excited species is then reacted rapidly with an additional preselected radiation, an electron or another chemical species so as to form a product containing the specific isotope, but having a mass different than the original species initially containing the particular isotope. The product and the remaining balance of the mixture is then caused to flow through a device which separates the product from the mixture based upon the increased mass differential.
