  • Publication number: 20230292890
    Abstract: A wearable jewelry includes a base member having a receiving chamber provided in a top portion thereof, a precious ornament and a rotation mechanism. The precious ornament element is provided with a mounting arrangement underneath, wherein the mounting arrangement is eccentrically provided with respect to the mass and shape of the ornament element. The rotatable mechanism includes a rotor body configured to be sited in the receiving chamber of the base member, a bearing device provided in the rotor body, and a rotor element rotatably mounted on the rotor body through the bearing device. The rotor element is affixed with the mounting arrangement of the ornament element so as to elevate and eccentrically mount the ornament element on top of the base member such that the ornament element is able to freely and smoothly rotate above the base member for any tangent force applied to the ornament element.

  • Patent number: 11400444
    Abstract: Open tubular capillary columns for liquid and ion chromatography, based upon an ionically impermeable polyolefin capillary having a bore with a sulfonate-group- or amine-group-functionalized internal surface. The capillary columns may include a coating of ion exchanging nanoparticles electrostatically bound to the functionalized internal surface. The capillary columns may be made by exposing the interior surface to a sulfonating reagent comprising chlorosulfonic acid (ClSO3H), preferably from 85 wt % to 95 wt % chlorosulfonic acid at a process temperature of 20 to 25° C. The interior surface may be subsequently exposed to an asymmetrical diamine to form a sulfonic mid-linkage to the diamine, i.e., to form a sulfonamide-linked, amine-group-functionalized internal surface. The coating may be provided by subsequently exposing the interior surface to an aqueous suspension of ion exchanging nanoparticles to electrostatically bond the ion exchanging nanoparticles to the functionalized internal surface.

The capillary columns may include a coating of ion exchanging nanoparticles electrostatically bound to the functionalized internal surface. The capillary columns may be made by exposing the interior surface to a sulfonating reagent comprising chlorosulfonic acid (CISO3H), preferably from 85 wt % to 95 wt % chlorosulfonic acid at a process temperature of 20 to 25° C. The interior surface may be subsequently exposed to an asymmetrical diamine to form a sulfonic mid-linkage to the diamine, i.e., to form a sulfonamide-linked, amine-group-functionalized internal surface.

  • Patent number: 10416137
    Abstract: An electrodialytic device for ion chromatography, including aspects functioning as an eluent suppressor device and aspects functioning as an eluent generator device. In general, the device includes a monolithic block of ionomeric polymer material having (1) a first channel with an inlet port, an outlet port, and an active length of exposed polymer material disposed therebetween, (2) a second channel having an inlet port, an outlet port, and an active length of exposed polymer material disposed therebetween, (3) a first and second at-least-partially exposed electrodes positioned in electrical communication with the second channel, with the second electrode disposed, at least in part, across the second channel from the first electrode. A current flowing between the electrodes will drive an electrodialytic migration of ions between the active lengths, from an eluent stream in the case of a suppression device or into an eluent stream in the case of a generator device.

  • Patent number: 6998384
    Abstract: A means and method for treating pulmonary fibrosis in animals is described. The compositions include surfactant lipids in a pharmaceutically acceptable carrier. Surfactant lipids have been found to suppress the synergistic effect of bleomycin and SP-A in enhancing proinflammatory cytokine production. Surfactant lipids are also effective in the prevention and treatment of pulmonary fibrosis resulting from exposure to inflammatory agents affecting cytokine production.
