  • Automatic darkening filter (ADF) eye protection device with improved drive circuitry
    Patent number: 8264265
    Abstract: An apparatus and methodology for operating an automatic darkening filter (ADF) eye protection device alternately applies an operating voltage to a pair of control terminals of an ADF device circuit in a continuing sequence, where a first polarity voltage is applied to the pair of terminals and then reversed. A delay period is provided between application of the alternating polarities. In some embodiments ground potential is applied to both terminals of the pair of terminals during the delay period.
    Type: Grant

  • Dry tree subsea well communications apparatus using variable tension large offset risers
    Publication number: 20070107906
    Abstract: Disclosed are compliant variable tension risers (106) to connect deep-water subsea wellheads (102) to a single floating platform (104). The variable tension risers (106) allow several subsea wellheads (102), in water depths from 4,000 to 10,000 feet, at lateral offsets from one-tenth to one-half of the depth, to tie back to a single floating dry tree semi-submersible platform (104).

  • DRY TREE SUBSEA WELL COMMUNICATIONS METHODS USING VARIABLE TENSION LARGE OFFSET RISERS
    Publication number: 20070107905
    Abstract: Disclosed are methods to counter buoyancy and install variable tension risers using a weighted chain ballast line. An example of an apparatus used in conjunction with the embodiments includes compliant variable tension risers to connect deep-water subsea wellheads to a single floating platform. The variable tension risers allow several subsea wellheads, in water depths from 4,000 to 10,000 feet, at lateral offsets from one-tenth to one-half of the depth, to tie back to a single floating dry tree semi-submersible platform.

  • Paper carrier stripping method and apparatus
    Patent number: 4135675
    Abstract: A flooring product is made on a paper carrier and the paper carrier is removed from the flooring just prior to the time the flooring is rolled up. The paper carrier, which is free from the flooring, is wrapped up with the roll of flooring to prevent adhesion between the flooring surfaces in the roll and to provide some physical stability to the roll of flooring when it is standing on its end.

  • Low molecular weight copolymers
    Patent number: 4005250
    Abstract: Disclosed are new copolymer mixtures derived from a vinyl ester, maleic anhydride, and a chain transfer agent such as tetrahydrofuran. The salts, such as the sodium salts, of these copolymer mixtures are useful as dispersants for finely divided particles such as kaolin.
