  • Patent number: 8153062
    Abstract: Electrochemical devices, methods, and systems for detecting and quantifying analytes are disclosed. A chemical detection reagent is locally generated in a test solution by electrochemical reaction of a precursor compound caused to migrate into the test solution from a precursor solution separated from the test solution by a cell separator. This approach provides precise metering of the reagent, via the charge passed, and avoids the need to store a reagent solution that may be chemically unstable. In one embodiment, the starch concentration in a colloidal solution can be measured via spectroscopic detection of a blue complex formed by the interaction of starch with iodine produced, on demand, by electrochemical oxidation of iodide ion. The approach may also be used to characterize certain types of analytes. The invention is amenable to automation and is particularly useful for on-line monitoring of production processes, including the inclusion of feed back loop mechanisms for process control.

  • Patent number: 6184265
    Abstract: Wear resistance and oxidation resistance of polymer material or a polymer component for bioimplantation are improved by packaging a polymer object in a sealed gas impermeable package substantially free of oxygen, irradiating the package with penetrating radiation to an extent sufficient to effect a desired substantial level of cross-linking within the polymer, and warming the packaged object while maintaining an elevated hydrostatic pressure to cause gases released during irradiation to recombine, stabilizing the material against subsequent oxidative change. The pressure stabilization terminates active sites, substantially eliminating free radicals. When applied to finished parts, the process simultaneously hardens and sterilizes the parts without degrading mechanical properties or dimensions. When applied to bulk material or unfinished parts, the part may be subsequent machined or otherwise finished, and sterilized by any conventional means.

  • Patent number: 5972292
    Abstract: A lens case for disinfecting, cleaning, or storing contact lenses is described that provides a sealing and venting system for allowing the release of gas while avoiding liquid leakage. The venting means allows venting of gas when internal pressure increases, while maintaining a seal that is substantially gas and liquid-impermeable at other times. The lens case includes a cap securable to a container barrel and a mating cap. The venting of gas occurs via a tortuous-path mechanism resulting from appropriate surface roughness being produced on at least one of a pair of mating surfaces forming a seal between the cap and the container. In a preferred embodiment, a relatively roughened surface is produced on a cap flange that is in the shape of a circular lip downwardly extending from the inner surface of the cap. The mating surface of the cap flange sealingly presses against the rim portion of the container.

  • Patent number: 5464595
    Abstract: In a method for aseptically drawing off food and drink into plastic containers, the container sheet is plasticized for molding the containers and subsequently molded in a sterile environment, after which the container recesses are filled and closed off by means of a lid sheet. For this method and before the filling process, the container sheet is acted upon in a longitudinal segment by means of steam for sterilization purposes and is cooled on its side opposite to the steam-impingement area. Before it is supplied to the container sheet, the lid sheet is sterilized. After they are sterilized and until they are combined, the lid sheet and the container sheet are kept in germ-free surroundings. In order to be sterilized on both sides, the container sheet is acted upon reciprocally in the flat state before it is molded, with steam in two consecutive treatment processes in, in each case, the same length segment, and, at the same time, cooled.
