  • Patent number: 4508602
    Abstract: A process for producing a concentrated aqueous solution of an alkali metal chlorate and an alkali metal chloride comprises feeding an aqueous alkali metal chloride solution to an electrolysis zone at a constant feed rate. Electric current is supplied to the electrolysis zone at an initial current load. The aqueous alkali metal chloride is electrolyzed to produce a concentrated chlorate solution comprised of an alkali metal chlorate and the alkali metal chloride. A portion of the concentrated solution is fed to an analysis zone and analyzed to measure the ratio of the concentration of the chlorate ion to the concentration of the chloride ion. The measured ratio is compared in a processing zone with a predetermined value range for the ratio and, where the measured ratio falls outside of the predetermined value range, altering the initial current load to the electrolysis zone. The concentrated alkali metal chlorate solution is recovered.

  • Patent number: 4504457
    Abstract: A continuous process for producing granular calcium hypochlorite particles comprises admixing lime and an aqueous liquid in a mixing zone to form a lime slurry. The lime slurry is fed into a crystallizing zone along with a calcium hypochlorite-containing liquid to produce a slurry of coarse dibasic calcium hypochlorite crystals and to elutriate a fines slurry from the crystallizing zone. The coarse dibasic calcium hypochlorite crystals are separated from a dibasic hypochlorite mother liquor and fed to a chlorinating zone. Reaction of the coarse dibasic calcium hypochlorite crystals with a chlorinating agent is conducted to produce a slurry of hemibasic calcium hypochlorite crystals. The slurry is fed to a separator to separate a hemibasic hypochlorite mother liquor from the hemibasic calcium hypochlorite crystals.

  • Patent number: 4498917
    Abstract: A system for machining and sizing optical fibers is described herein. The system uses a laser beam to machine oversized regions of a buffer material surrounding an optical fiber to create a coated optical fiber having a substantially uniform maximum outer dimension that is within a desired tolerance. The machining of the buffer material is accomplished by forming a substantially cylindrical laser beam having a hollow central portion and passing the optical fiber to be sized through the hollow central portion. The hollow central portion has a dimension or diameter substantially equal to a desired outer dimension or diameter for the optical fiber. Any discontinuities or oversized regions of buffer material outside the hollow central portion diameter will be contacted and vaporized by the substantially cylindrical laser beam.
