| 20100000037 | Speed Regulated Pipeline Pig - A pipeline pig includes a venturi and a modulating valve located rearward of the inlet side of the venturi. When the valve is in the open position, a predetermined maximum bypass flow is allowed through the venturi. The closed position allows a predetermined minimum bypass flow. The valve may be a poppet-style valve or a frusto-conical shaped stopper. The stopper has sufficient mass and/or aerodynamic drag to overcome the spring force holding the valve in the open position. When the pig stalls, the valve closes and the stopper chokes bypass flow through the venturi. When the pig starts running again, the valve opens as inertia forces the stopper away from the inlet side of the venturi. Also, as friction of the pig increases due to changes in the internal diameter of the pipeline or accumulation of debris ahead of the pig, increased airflow across the valve creates drag sufficient to partially overcome the spring force, thus keeping the pig moving at a desirable rate of travel. | 01-07-2010 |
| 20100072204 | Two-Piece Closure Device - A closure device includes a door carrying a series of interconnected shear blocks and a keystone shear block designed to transfer stresses created by pressure acting on the door to a surrounding hub. Each interconnected shear block has a limited rotation relative to its adjacent blocks. A holding band operating handle is in communication with a driving link which, in turn, is in communication with the keystone shear block. Actuating the handle causes the keystone shear block to move in an upward vertical direction. The linear movement of the keystone shear block allows the limited rotation of the interconnected shear blocks to occur, thereby causing the circumferential holding band to collapse within itself from an expanded-engaged position to a contracted-removed position relative to said hub. A pressure warning lock provides a safety device and prevents actuation of the holding band operating handle when the pressure chamber is under pressure. | 03-25-2010 |
| 20100295543 | Magnetometer-based Detector for Objects in a Pipeline - A system and method for detecting the passage of an object in a pipeline includes a non-intrusive detection device that houses one or more shielded magnetometer sensors and a microcontroller with adaptive thresholding detection means. The adaptive thresholding detection means removes outlier data from the magnetic flux data stream and then passes the outlier-free data stream through four low pass filters. A smoothed magnitude of the data stream is compared to detection limits and, if a passage event has occurred, a recent detection is indicated, a counter of a display unit is incremented, a time of passage is recorded, and both statistics are displayed on the display unit. Because a single object may produce multiple magnetic fields, the detector may be locked-out for a predetermined period of time after the passage event to prevent a second detection of the same object as it passes the detection device. | 11-25-2010 |
| 20110120499 | Method and System for an Injectable Foam Pig - This invention relates to a method and system for inserting a larger diameter foam pig into a tubular member, such as a pipe or pipeline, through a smaller diameter access connection when the tubular member contains a pressurized product flow. A foam pig sized appropriately for the tubular member is reduced in size so as to reside within a canister or vacuum-packed bag within the canister. The canister is located above an access connection to the tubular member. The reduced size foam pig is then injected from the canister through the small diameter access connection. As the foam pig enters into the interior space of the tubular member, the pig expands and turns and travels downstream of the access connection. The expanded foam pig has a diameter substantially equal to that of the tubular member and a volume substantially greater than that of the foam pig prior to its injection. | 05-26-2011 |
| 20110138555 | Bidirectional Bristle Pig with Sliding Collar - A bidirectional bristle pig provides a means for collapsing or restraining the bristles so that the pig may be used in a reciprocating manner or, when the pig becomes stuck, the pig may be easily retrieved in a direction opposite that of the initial direction of travel. The bristle pig has at least one set of outwardly projecting cleaning wires or bristles located toward one end of the pig body and a sliding collar. The sliding collar moves between a first position and a second position to restrain the bristles at the desired leading end of the pig and forces the bristles downward and away from the inner wall surface of the pipeline. In the restrained state, the bristles no longer interfere with the movement of the pig in the desired direction. The sliding collar may move in response to pipeline pressure or may include a tether line. | 06-16-2011 |
