  • Patent number: 5890226
    Abstract: The lower open end of the sleeves of the liner are detachably connected to the lower open end of the sleeves of the shell by attachments secured to the shell sleeves. The attachments include annular portions which overlap the lower ends of the liner sleeves to prevent liquid from flowing between the liner sleeves and the shell sleeves. Each liner sleeve includes an outer moisture barrier and an inner moisture barrier with a thermal barrier disposed between the inner and outer moisture barriers. The inner moisture barrier of each liner sleeve is permanently connected circumferentially to a wrister by stitching. The inner moisture barrier extends upwardly from the lower end of the liner sleeve and is then folded downwardly to the wrister, the inner moisture barrier being stitched to the thermal barrier adjacent the location where the inner moisture barriere is folded downwardly to form a sleeve well within the liner sleeve.

  • Patent number: 5888462
    Abstract: A method of solvent extraction of a nickel sulfate solution uses a multi-stage, counter-current, organic solvent extraction system composed of at least two extractors connected in series, and includes a first extraction step of feeding a crude nickel sulfate solution that contains sodium and ammonium impurities into a second-stage extractor, wherein it is treated in countercurrent flow and at a pH of 6.5 to 7.0 with an organic extractant fed into the second-stage extractor from the first-stage extractor, to thereby extract some of nickel in the crude nickel sulfate solution into the organic extractant; and a second extraction step of transferring the nickel-containing, organic phase to an organic phase-scrubbing step to remove sodium and ammonium, while transferring the nickel sulfate solution, from the first extraction step and from which some of nickel has been removed, to the first-stage extractor, wherein it is treated in countercurrent flow and at a pH of 5.5 to 6.

  • Patent number: 5886603
    Abstract: A detent mechanism comprising a support member having a fixed seating member comprising opposite sides; a first spring for exerting a first spring force, disposed between one side of the fixed seating member and a first sliding member, further comprising a second spring member exerting a second spring force less than said first spring force, disposed between the other side of said fixed seating member and a second sliding member, whereby the forces of the springs are directed to operate on said first and second sliding members in opposite directions. A push button can apply an external force to the first sliding member to move it from a first position relative to the fixed seating member to a second position against the action of said first spring force. A detent mechanism connects the first and second sliding members when the first sliding member is in its second position and the second slidable member is in a first position.

  • Patent number: 5885535
    Abstract: A process for extracting and separating silver safely and selectively from a raw material containing slightly soluble silver compounds and recovering silver from the extract in a simple manner without resorting to electrolysis or a special reducing agent, and further recovering high-purity silver, includes mixing the raw material with an organic solvent solution of an organophosphorus compound containing in the molecule sulfur in the form of S.sup.2- ions, thereby extracting silver into an organic phase simultaneously with dissolving the slightly soluble silver compounds, stripping the silver from the organic phase containing the extracted silver with an aqueous solution of alkali sulfite and forming a stripping solution, and reducing the stripping solution to separate silver therefrom.

  • Patent number: 5884332
    Abstract: An outer protective shell of either a jacket or trousers has a torso portion and a pair of appendage portions connected to the torso portion. A liner is disposed within the shell and includes an outer moisture barrier and an inner thermal barrier. The moisture barrier is formed of a plurality of pieces joined together at seams. Sealing tapes on the inner surface of the moisture barrier are disposed over the seams to provide a waterproof seal at the seams. Lower edge portions of the moisture barrier and the thermal barrier are detachably connected to one another at spaced points so that the moisture barrier and the thermal barrier can be manually separated from one another to visually inspect said sealing tapes at all of said seams. In the jacket, the remaining edge portions of the barriers are permanently connected to one another. These remaining edge portions are detachably connected to the shell at spaced locations along the remaining edge portions.

  • Patent number: 5876181
    Abstract: The described wind turbine has a set of propeller type wind force collecting rotor turbines which is comprised of an up-wind auxiliary rotor blade turbine, being disposed on the front end of the combined bevel-planet gear assembly, and a down-wind main rotor blade turbine together with attached extender having twice the radius of the auxiliary rotor turbine. These rotor blades rotate in opposite directions with respect to one another, and the extender enables the main turbine to be activated by normal wind speed without aerodynamic wake turbulence effects created by the movement of the auxiliary rotor blade. The super-large scale, integrated, multi-unit rotor blade wind turbine has four sets of wind force collecting rotor blade turbines composed of an auxiliary up-wind rotor turbine and three down-wind rotor turbine units evenly spaced around a central pivotal rotor hub on extenders which arc the same length as the radius of the auxiliary turbine blade.
