  • Patent number: 6050342
    Abstract: Disclosed herein is a method and apparatus for setting a compression seal pack in a well without rotation of the pipe string and setting mandrel. The setting device includes a release device and a moveable member. The release device secures a setting mandrel in a non-engaged position with respect to the seal packer. The moveable member is positionable to a first position, where the setting mandrel is locked in its non-engaged position, and to a second position, where the release device is free and the setting mandrel may move with respect to the seal packer. The method disclosed herein includes coupling the setting device to a compression set packer, positioning a setting mandrel within the seal packer and setting device, positioning the seal packer at the desired location in a well, releasing the setting mandrel from its non-engaged position with respect to the seal packer and lowering the setting mandrel into engagement with said packer to set the packer in the well.

  • Patent number: 6035914
    Abstract: Fluorescent dichroic fibers randomly incorporated within a media provide an improved method for authentication and counterfeiting protection. The dichroism is provided by an alignment of fluorescent molecules along the length of the fibers. The fluorescent fibers provide an authentication mechanism of varying levels of capability. The authentication signature depends on four parameters; the x,y position, the dichroism and the local environment. The availability of so many non-deterministic variables makes production of counterfeit articles (e.g., currency, credit cards, etc.) essentially impossible. Counterfeit-resistant articles, an apparatus for authenticating articles, and a process for forming counterfeit-resistant media are also provided.

  • Patent number: 6033546
    Abstract: A microchip laboratory system and method provide fluid manipulations for a variety of applications, including sample injection for microchip chemical separations. The microchip is fabricated using standard photolithographic procedures and chemical wet etching, with the substrate and cover plate joined using direct bonding. Capillary electrophoresis and electrochromatography are performed in channels formed in the substrate. Analytes are loaded into a four-way intersection of channels by electrokinetically pumping the analyte through the intersection, followed by switching of the potentials to force an analyte plug into the separation channel.

  • Patent number: 6001229
    Abstract: A microchip apparatus and method provide fluidic manipulations for a variety of applications, including sample injection for microchip liquid chromatography. The microchip is fabricated using standard photolithographic procedures and chemical wet etching, with the substrate and cover plate joined using direct bonding. Capillary electrophoresis is performed in channels formed in the substrate. Injections are made by electro-osmotically pumping sample through the injection channel that crosses the separation channel, followed by a switching of the potentials to force a plug into the separation channel.

  • Patent number: 5646447
    Abstract: A socket for a ball grid array integrated circuit package (BGA) with an array of electrical contacts (*12) that extend through holes in a slidable plate. The arrangement of spacing the holes (14) and the electrical contacts therein provide entry openings that allow the ball contacts (16) of a BGA package to enter the openings. The contacts are cupped or angled to mate with the side and top of the ball contacts of the ball grid array package. The contact surface of the ball grid array package is vertically inserted into the socket without any interfering structure, and there are guide surfaces to align the ball contacts with the openings. The plate (3) is driven parallel to the plane of the ball contacts in a manner that reduces the entry hole opening by means of a rotating cam placed at one end rotated by a torsion spring.
