20080257420 | SLAM SHUT SAFETY DEVICE - A safety device for a gas distribution system includes a valve body, an upper casing attached to the valve body, the upper casing housing two springs. The two springs are co-axially located and separated by a casting tube. Further, the two springs are attached to a movable diaphragm that is exposed to gas system pressure. A snap ring flange is also attached to the valve body, the snap ring flange being used to secure the safety device to a main regulator in the gas distribution system. The valve body also includes a cam mounted within the valve body. A limit switch is directly connected to the cam such that the limit switch moves directly in response to movement of the diaphragm. Additionally, a reset pin extends from the valve body and interacts with the cam such that the cam may be reset from a closed position to an open position by moving the reset pin. | 10-23-2008 |

20130309015 | PIPELAYING - An accessory for a subsea pipeline such as an in-line tee having a rigid pipe support frame defining a pipe course and at least one carriage arranged to support a pipe or a fitting attached to a pipe. The carriage is movable with respect to the frame in a direction generally parallel to the pipe course. The carriage is attached to the frame via at least one angularly movable connection that allows a pipe or fitting supported by the carriage to tilt locally with respect to the frame as the pipe bends during laying. Pipe stiffness is therefore independent from the stiffness of the accessory. The stiffened section of the pipe is limited to a short length of the carriage. This is compatible with the small bending radius of the pipe on a stinger. | 11-21-2013 |

20080317666 | Colonic Delivery of Active Agents - Drug delivery devices that are orally administered, and that release active ingredients in the colon, are disclosed. In one embodiment, the active ingredients are those that inactivate antibiotics, such as macrolides, quinolones and beta-lactam containing antibiotics. One example of a suitable active agent is an enzyme such as beta-lactamases. In another embodiment, the active agents are those that specifically treat colonic disorders, such as Chrohn's Disease, irritable bowel syndrome, ulcerative colitis, colorectal cancer or constipation. The drug delivery devices are in the form of beads of pectin, crosslinked with calcium and reticulated with polyethyleneimine. The high crosslink density of the polyethyleneimine is believed to stabilize the pectin beads for a sufficient amount of time such that a substantial amount of the active ingredients can be administered directly to the colon. Advantageously, the amount of polyethyleneimine is sufficient to allow a substantial portion of the pectin beads to pass through the gastrointestinal tract to the colon without releasing the active agent, and is also sufficient such that the pectin beads are sufficiently degraded in the colon to release an effective amount of the active agent. | 12-25-2008 |

20160133000 | METHOD FOR PROCESSING A DIGITAL IMAGE OF THE SURFACE OF A TYRE IN ORDER TO DETECT AN ANOMALY - To analyze a tyre surface, a 3D elevational image is captured, which is formed of pixels representing points on the surface. Each point is assigned a grey-level value proportional to its elevation relative to a surface level. Based on the elevations in the elevational image, an orientational image is formed showing elevation gradients of the surface. In the orientational image, which is formed of pixels representing points on the surface, each point is assigned a grey-level value proportional to an angle formed with a direction given by a projection in an image plane of a non-zero norm vector substantially corresponding, at this point, to a gradient vector tangent to the surface and oriented in a direction of greatest slope. A filtered image is determined by transforming the orientational image using a filter to select areas that include structures similar to those in a reference orientational image of a blow hole. | 05-12-2016 |

The method includes: extracting contours of graphic elements of an image of a 3D profile of a surface to be inspected; transforming the reference surface by establishing a correspondence between the contours of the graphic elements of the surface to be inspected and contours of identical graphic elements of the reference surface using a series of transformations; associating a B-spline surface, which includes control points, with the graphic elements of the transformed reference surface; and deforming the contours of the graphic elements of the reference surface by modifying positions of the control points of the B-spline surface so as to minimize distances between the contours of the graphic elements of the reference surface and the contours of the graphic elements of the surface to be inspected corresponding thereto. | 10-10-2013 |
