  • Patent number: 4867544
    Abstract: Optical glass elements with graded refraction index in the infra red region. The elements are made of doped oxygen free chalcogenide glass. The concentration of the dopant decreases from the periphery inward. Typical examples of dopants are As, S and Se.The glass elements are prepared by exposing an oxygen free chalcogenide glass to a molten chemical element or salt at about 150.degree.-400.degree. C. in an oxygen free atmosphere.

  • Patent number: 4722605
    Abstract: A Moire system for linear measurement of an unknown distance defined by two surfaces, a collimated light source, a first grating between light source and the surfaces, a second grating positioned to receive collimated light from the surfaces after the light has reached the surfaces from the first grating, the first and second gratings being rotated relative to each other by a small angle .theta., a screen located after the second grating for receiving Moire patterns caused by the first and second gratings, and a mechanism for shifting the patterns as a function of the unknown distance whereby measurements of the amount of shifting is determinative of the unknown distance.

  • Patent number: 4600304
    Abstract: An optical instrument arrangement for determining the horizontality of a measured surface, where the arrangement comprises a solid reflecting device on a measured surface, a liquid reflecting device on a measured surface, a collimated light source positioned to direct collimated light beams onto both the solid reflecting device and the liquid reflecting device, a device for generating a first Moire fringe pattern from the solid light reflecting device and for also generating a second Moire pattern from the liquid reflecting device; and a device for simultaneously viewing the first and second Moire patterns to determine the horizontality of the measured surface from the shift of the second Moire pattern relative to the first Moire pattern.

  • Patent number: 4599221
    Abstract: Recovery of uranium from crude wet process phosphoric acid (WPA) by cation exchange using as cation exchanger a resin comprising active amino phosphonic or hydroxy phosphonic groups linked to a matrix. The operational steps comprise reduction of uranium in the WPA to the tetravalent state, contacting the WPA with the cation exchange resin to load the latter with tetravalent uranium, displacing Fe.sup.+2 from the resin, washing the resin with aqueous ammonia, eluting the resin with a carbonate-bicarbonate solution and precipitating uranium from the eluate.

  • Patent number: 4590681
    Abstract: A level comprises a sealed casing which holds a liquid and has a flat bottom end. It also includes a light admissive top section, bearing a periodic grating of alternating transparent and opaque stripes. A float is in the liquid inside a compartment of the casing underneath the light admissive top section. The float is capable of changing its position inside the chamber so as to retain its position relative to the horizon when the chamber is filled, and a mirror on the top face of said float.

  • Patent number: 4569590
    Abstract: A system for determining the index of refraction of a sample fluid in which light from a collimated light source is directed through a light pervious cell in which sample and reference fluids are held. The light from the collimated light source which is transmitted through the cell is deflected and is then directed through a pair of gratings to establish patterns. When the cell contains a reference fluid therein, first patterns are established, and second patterns are then established by replacing the reference fluid with the sample fluid. A measurement of the change between the first patterns and the second patterns is used for determining the index of refraction of the sample fluid.
