Apparatus for measuring current in a conductor characterized by a magneto-optical current sensor employing the Faraday effect to measure current in a high voltage transmission line. Polarized light having a predetermined plane of polarization is directed into the sensor which plane of polarization is rotated by magnetic field lines generated by the current in the conductor. A bimetal coil rotates the sensor to achieve temperature stability of the current signal in the temperature range of -40.degree. C. to 140.degree. C.

Temperature stabilized Faraday rotator current sensor by thermal

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.
