  • Publication number: 20150233202
    Abstract: A riser disconnect/reconnect system having a disconnection package (RDP) and a modified lower marine riser package (LMRP) are provided for quick disconnection of the marine drilling riser (MDR) from the LMRP to facilitate access to the LMRP or BOP stack. The RDP includes a flex joint and a hydraulically-actuated release connector (RC) with a connecting mandrel that engages a modified LMRP. In an emergency event, the RDP is disconnected from the LMRP allowing access to the BOP stack for intervention. The RDP may be disconnected from the LMRP for recovery of the LMRP or BOP stack to the surface for repair or maintenance without recovering the MDR. The RC joins the flex joint to the uppermost annular blowout preventer in the LMRP. The release connector can be used in a standard or inverted position. Also provided are structural cages with complementary stab plates allowing access to various bypass ports and controls.

  • Patent number: 9004084
    Abstract: An apparatus and method for removing waste from a soiled container that houses laboratory animals and has an opening is disclosed. The apparatus includes a conveyor having a receiving end for receiving containers from a stack of containers. The stack is disposed such that the openings are upwardly oriented. The apparatus also includes a manipulator that aligns with and engages an uppermost container of the stack and causes the uppermost container to be separated from the stack and to be flipped over onto the receiving end of the conveyor such that the opening is downwardly disposed. Waste discarded from the container falls through openings in the conveyor, and a waste receptacle disposed below the conveyor collects the discarded waste. The conveyor advances to transport the container away from the receiving end toward a discharge end of the conveyor.

  • Publication number: 20140289447
    Abstract: An apparatus, system, and method are disclosed for storage space recovery. A storage division selection module selects a first storage division for recovery. The first storage division comprises a portion of solid-state storage in a solid-state storage device. A data recovery module reads valid data from the first storage division in response to selecting the first storage division for recovery. The data recovery module stores the valid data in a second storage division of the solid-state storage device. The data recovery module passes the valid data through at least a portion of a write data pipeline for the solid-state storage device without passing the valid data to a host device and/or without routing the valid data outside of a solid-state storage controller for the solid-state storage device.

  • Publication number: 20140176726
    Abstract: An image processor for processing images received from a plurality of image sensors affixed to a platform, each image sensor having a field of view that at least partially overlaps with the field of view of another one of the other image sensors. For each image sensor, the image processor uses motion data that is received from a motion sensor associated with the respective image sensor, together with reference motion data from a motion sensor affixed to the platform, to determine whether the image sensor has moved from an expected position during the interval between its capturing a first and second image. The image processor adjusts the second image received from each respective image sensor accordingly and combines the adjusted images into a single output image.

  • Patent number: 8715499
    Abstract: A method of operating chromatography column apparatus comprising a column tube (101) and first and second discrete end cell structures, associated with the respective ends of the column tube and positionable to close off the column tube and define therein a column space for retaining chromatography medium in use of the apparatus. The first end cell portion comprises a piston portion (106) fitting slidably in the column tube. The column tube and the second end cell structure are separated to provide an access spacing between them. The piston portion (106) of the first end cell structure is advanced through the column tube to expose it at the open second end of the column tube, for maintenance of the piston portion thus exposed. Corresponding chromatography apparatus is another aspect of the disclosure.

  • Publication number: 20140057293
    Abstract: Conjugates of 1,3-bis(1,4,7-triazacyclonon-1-yl)-2-hydroxypropanes with a variety of conjugating members are used in the formation of dinuclear metal complexes which bind to phosphate esters. By virtue of their conjugated forms, the complexes are incorporated into chromatographic media, affinity binding reagents, and dyes, which make the complexes useful in a wide range of assays, separations, and purifications. In addition, dinuclear metal complexes of 1,3-bis(1,4,7-triazacyclonon-1-yl)-2-hydroxypropanes that are not so conjugated are used in the detection of phosphate esters of biological species by either MALDI-TOF mass spectrometry or by dye displacement.

  • Publication number: 20130144847
    Abstract: A system, computer-implemented method and computer-readable medium for managing duplicate articles are provided. A first and a second potentially duplicate article of a magazine edition are accessed, the first article associated with a first title and a first URL and the second article associated with a second title and a second URL. The titles are normalized. The first normalized title is compared to the second normalized title and the first URL is compared to the second URL to determine whether the first article and the second article are duplicates. It is determined that the first article and the second article are duplicates when the first normalized title is considered similar to the second normalized title and the first URL is considered similar to the second URL. Otherwise, it is determined that the first article and the second article are not duplicates.
