  • Patent number: 8001988
    Abstract: A method according to this invention employs a set of valves, a series of pressure checks, and a physical stop for verifying the closing of a locking system of a cylindrical passageway. The method may also employ an equalization piping. The valves isolate a tapping machine, a pipeline, and the equalization piping from one another so that product cannot flow from one to the other. The valves are then opened as a series of pressure checks are performed. A completion plug is then lowered into the passageway until the plug comes to rest within the passageway and is oriented so that a locking ring of the plug is in a filly expanded position. The expanded position is then confirmed by raising the plug until its upward travel is restricted. The plug is then released and pressure above the plug is reduced to 0 psi gauge.

  • Patent number: 7957546
    Abstract: A multi-channel noise reduction system provides improved noise reduction with direct instrument tracking of all channels. In a two channel noise reduction system, both channels detect and track the input level and dynamic range of the guitar directly with one channel of dynamic noise reduction between the guitar and the input of a guitar amplifier to eliminate the noise of the instrument and another channel of noise reduction connected in the effects loop of the guitar amplifier. Multiple channels of noise reduction can be implemented with separated threshold controls and with low level expansion and dynamic filtering being combined so as to detect and track the input level and dynamic range of the guitar directly. A buffer amplifier can be used to feed the direct guitar signal to the detectors of the noise reduction system and the input of a stereo guitar system.

  • Patent number: 7942162
    Abstract: A flow splitter that divides a two-phase (gas-liquid) inlet stream or a one-phase (liquid-liquid) inlet stream into equal and substantially balanced parts for distribution to an equal number of outlets horizontally oriented and connected to the flow splitter. Because of the design of the flow splitter, no control instrumentation or retention time is required during a split. Openings in each face of the flow splitter help to equalize pressure in the split and allow liquid to fill an end chamber that supports impact forces on a wedge-shaped spreader oriented with its leading edge toward an inlet stream.

  • Patent number: 7926516
    Abstract: A repair device and method for its use includes plugs that pressure isolate an internally damaged pipeline section and an hermetically sealed housing that contains a length of composite material and a means for controllably releasing the composite material. In a preferred embodiment, the composite material is a pre-cured composite plank and the releasing means is a rotatable carriage assembly. The carriage assembly includes pairs of rollers that maintain the composite material in its coiled state and provide for its controlled release onto the interior wall of the pipeline. The carriage assembly also includes a nozzle for injecting an adhesive into a roller. The roller applies the adhesive onto the interior wall surface and then presses the composite material into the adhesive as the carriage assembly rotates and the composite material uncoils. A pneumatic or electric motor may be used to power the carriage assembly.

  • Patent number: 7900655
    Abstract: A method for repairing and reinforcing a pipeline includes covering a defect in a pipeline section with a composite wrap, isolating the wrap from the ambient environment, and applying a compressive force on the wrap so that the pressure on the wrap is substantially equal to the pipeline pressure. Isolating the wrap involves the use of a housing having a cavity that substantially conforms to the shape of the wrapped section. The cavity may contain a pressurized gas or liquid. Because the pressure acting on the surface of the wrap is at least substantially equal to the pressure of the pipeline section, the wrap cures as if the pipeline is at zero pressure. Once the wrap has effectively cured, the compressive force may be relieved and the housing removed. The composite is now under load and is immediately sharing load with the pipeline.
