  • Patent number: 9341653
    Abstract: An optical sensor assembly, for installation on a current carrying cable, senses the current in the cable and provides an electrical output indicating the current. To sense the current, a magnetic concentrator is placed in close proximity to the cable and creates a magnetic field representing current in the cable. An optical current sensor, within the created magnetic field, exposes a beam of polarized light to the magnetic field. The beam of polarized light is rotated thereby, by Faraday effect, according to the current in the cable. The amount of rotation is analyzed and converted to electrical signals to portray the current in the cable. The electrical signals may be processed, evaluated and analyzed to provide one or more of several elements of quality of the current in the cable.

  • Patent number: 6475390
    Abstract: A separation process is described for separation of a nutrient from divalent ions of an aqueous solution. The aqueous solution is contacted with an ion exchange resin that includes monovalent ions until the concentration of divalent ions in the aqueous solution has been depleted and an eluate is collected. The eluate is then subjected to a process, preferably a nanofiltration membrane process, capable of separating monovalent ions to obtain a permeate fraction including monovalent ions and a retentate fraction including the nutrient. The retentate fraction is then separated into fractions with at least one fraction including a major portion of the nutrient. The ion exchange resin is then regenerated by contacting it with a solution including the permeate fraction until a major portion of the divalent ions have been replaced by monovalent ions.

  • Patent number: 6445514
    Abstract: A micro-positioning system for accurately positioning an optical element relative to an optical device such as a laser diode, Vertical Cavity Surface Emitting Laser (VCSEL), Resonant Cavity Photo Detector (RCPD), or some other type of optical device. The micro-positioning system is adapted to move the optical element independently in both the X and Y directions. The optical element preferably has at least two regions where the optical characteristics are different. In operation, the optical element is selectively moved so that a light beam intersects a selected region of the optical element. Because the optical characteristics of the optical element are different in different regions, the optical element produces a different optical result as the light beam is moved between regions.

  • Patent number: 6215940
    Abstract: A high voltage insulator for use with optical fibers includes an insulative support rod with at least one optical fiber wrapped about the support rod. The optical fiber and support rod are covered by an outer elastomeric skirted insulative sleeve which squeezes the optical fibers against the support rod. A dielectric sealant, such as a silicone gel, is dispersed along the optical fiber to fill any voids which occur adjacent the optical fiber, thereby providing a void-free bond between the interior surfaces of the insulator. The elastomeric outer sleeve provides a resilient barrier against the ingress of moisture. In a preferred embodiment, an inner layer of elastomeric material is provided between the support rod and the optical fiber to provide additional cushioning of the fiber and to reduce the size of voids which may occur adjacent the fiber.

  • Patent number: 5729005
    Abstract: A fiber optic subassembly for a Faraday-effect current sensor has an optical sensing fiber supported by a tubular holder in a square or rectangular configuration, with the three of the four corners thereof designed with bends which have a net zero bend-induced birefringence. The bends are formed by providing two loops which have effective angles of about 90.degree., the two loops lying in orthogonal planes, such that the fast axis of birefringence in the first loop is parallel to the slow axis of birefringence in the second loop, and the slow axis of birefringence in the first loop is parallel to the fast axis of birefringence in the second loop. In this manner, retardance accumulated in the first loop is offset by retardance accumulated in the second loop. If the loops are substantially identical, the offsetting of the retardance is effectively complete such that the bend exhibits negligible bend-induced birefringence.

  • Patent number: 4053702
    Abstract: A means for relieving dielectric stress at a termination of a shielded and insulated high voltage cable. A smooth geometry high permittivity homogeneous material tube coaxially contacts both the ground electrode and the high voltage electrode. The tube consists of an elastomeric material having a permittivity in a range of from 10 to 25. The elastomeric material is non-rigid, thereby enabling the tube to be more readily fitted firmly around the cable and into the housing of the stress relief means. The ground electrode is the outer portion of the housing and diverges from the opening of the housing at the vicinity thereof in a direction toward the high voltage electrode. This dielectric stress relief means provides a satisfactory electric field gradient in applications wherein the rating is in a range from 15 kilovolts to 35 kilovolts.
