Abstract: Isotopes of either germanium or silicon are separated by a chemical exchange reaction. Preferably the compound is a hydro halide or halide composition and the donor can be a wide variety of compounds such as a lower molecular weight alcohol.

Abstract: An apparatus for augmenting the coalescence of a component of an oil/water mixture employs an elongated cylindrical vessel having a fluid inlet at one end and a fluid outlet at the other end and an electrically conductive sidewall. An electrode is positioned within the vessel, concentric with the vessel sidewall, and between the fluid inlet and fluid outlet. An electrical potential is applied between the electrode and the vessel sidewall. A distributor plate is positioned within the vessel and between the vessel fluid inlet and the electrode. The distributor plate is shaped to cause fluid passing through it to move in a spiral pattern within the vessel and around the electrode as the fluid moves towards the fluid outlet.

Abstract: A method and apparatus for augmenting the coalescence of water in a water-in-oil emulsion. The apparatus includes a tubular vessel having a cylindrical side wall and opposed ends. A tangential inlet in the cylindrical side wall is adjacent one of the vessel ends. A tubular electrode having an external diameter less than the internal diameter of the vessel extends concentrically within the vessel from the one end less than the entire length of the vessel. An elongated electrode extends axially and concentrically within the tubular electrode from the one end. An outlet is provided in the one end between the tubular electrode and the elongated electrode. The inlet and outlet serve to cause fluid to initially flow through the vessel in a circumferential path outside the tubular electrode and thereafter axially through the tubular electrode to the outlet. An electrical potential is applied between the electrodes and the vessel.
