摘要： This invention relates to a method for separation of isotopes, that is, to obtain isotopically pure fractions by separating natural occuring isotope mixtures in elements, where hydrogen is employed as ligand on the elements that are to be isotopically separated, and where the resulting compounds are gaseous at practical temperatures and pressures. More specific, the invention relates to a method for obtaining an isotopically pure 28SiH4 in industrial scale by separating the isotopes in a chromatographic column.

摘要： A method of yielding selectively a desired enrichment in a specific isotope including the steps of inputting into a spinning chamber a gas from which the specific isotope is to be isolated, radiating the gas with frequencies characteristic of the absorption of a particular isotope of the atomic or molecular gas, thereby inducing a photoionization reaction of the desired isotope, and collecting the specific isotope ion by suitable ion collection means.

摘要： Contactor-separator units of a sub-assembly in which an isotopic exchange between two immiscible phases takes place are associated in m lines and n columns. One of the phases leaving a contactor-separator unit is directly directed to the adjacent contactor-separator unit in the same line, whereas the other phase leaving the same contactor-separator unit, is directed directly to the adjacent contactor-separator unit in the same column. Each of the m lines and n columns is provided with a single pump. The instantaneous flow rates of each phase are substantially equal at the input and the output of each of the contactor-separator units.

摘要： Apparatus wherein a partially ionized mass of gas is enclosed by a rotationally symmetric, axially elongate housing and set in rotation by a force which arises as a result of a substantially axial magnetic field constant in time and an electric current having a non-zero vector component in the radial direction, whereby positively charged ions originating from a centralized axial gas discharge arc region and moving at a high speed of rotation set the whole mass of gas in rotation by pulse transfer, said housing being lined on the inside with annular wall electrodes segmented in non-azimuthal direction and arranged against each other; the inside wall of said housing at an extremity thereof curving toward the center axis and approaching a centrally mounted electrode of opposite polarity, the wall electrodes being connected with variable resistors which are adjusted so that the voltage applied to the wall electrodes increases blockwise from a minimum value at a chosen point on the axis of the housing to the grid-or anode voltage of the said axial gas discharge arc region, whereby the wall electrode which is closest to the central electrode exhibits with respect thereto the smallest potential difference of all the wall electrodes, in an extreme case the potential difference being zero.

摘要： In a device for separating the components of a gas mixture and especially isotopic species of different masses such as U.sup.235 and U.sup.238, the mixture is passed through a vessel having an axis of revolution and forms a vortex, the axis of which coincides with the axis of the vessel. A plurality of openings for the admission of the gas mixture are spaced at intervals over the entire surface of the vessel. Means for withdrawing fractions enriched in one of the components of the mixture to varying degrees are centered on the axis of the vessel.
