    摘要: The method of controlling the load on a drill bit drilling a hole by providing differential pressure across a seal area on a drilling assembly to increase the bit load and providing a relief valve from the annular area above the seal to the bore returning fluid to the surface to limit the maximum differential pressure to limit the maximum load allowed.

    摘要: A means of alleviating or preventing flooding in geographic areas which are normally drained by slow moving water in ditches, rivers, bayous or other waterways of relatively shallow slope by using a water thrusting means to add kinetic energy and therefore velocity to a portion of the water, mixing the portion back in the main body of water in a downstream direction to increase the average velocity downstream of the main body of water, and thereby move water away from the flooding area to a remote area more quickly than would occur naturally.

    摘要: The method of preventing pressures higher than a predetermined pressure in the front ram seals of blowout preventer rams comprising providing blowout preventer rams suitable for sealing across the bore of a blowout preventer stack, providing seals on the blowout preventer rams which sealingly isolate the bore area below or upstream of the blowout preventer rams from the area above or downstream of the blowout preventer rams, providing a passageway from the front to the rear of the blowout preventer rams to vent the upstream or higher pressures to the rear of the blowout preventer rams, and communicating the resilient seal material in the front ram seals with a pressure release piston which will relieve the pressure at the predetermined pressure.

    摘要: The method of providing a clamping connection comprising providing one or more clamping hubs, providing two or more clamping segments to engage the clamping hubs, constraining the clamping segments to move approximately radially with respect to the clamp hubs, providing a tension band around the clamping segments which slides circumferentially relative to the clamping segments, and adjusting the ratio of the contact area of the tension band to the clamping hubs and the area of the clamping hubs to compensate for the difference in loading on the clamping hub due to sliding friction between the tension band and the clamping hubs.

    摘要: The method of providing blowout preventer shear rams which will shear pipe then provide a face-to-face compression seal comprising providing an upper shear ram having an upper shear ram blade and a pipe lifter, providing a lower shear ram having a lower shear ram blade, and a pipe lifter, providing a face-to-face seal, moving the upper and lower shear rams into the bore towards one another, shearing the pipe in the bore of the blowout preventer, engaging the upper sheared portion of the pipe with the pipe lifters, lifting the upper sheared portion of the pipe with the pipe lifters to a position above the face-to-face seal, engaging the face-to-face compression seal to effect a seal across the bore.

    摘要: The method of using the flow within a pipeline to clean the inner wall of the pipeline including placing the cleaning pig into the pipeline to be cleaned at a first location, using a restraining rope or cable to cause the cleaning pig to move along the pipeline at a speed slower than the speed of the flow within the pipeline and thereby causing a pressure differential between the upstream side and the downstream side of the cleaning pig, providing one or more jetting nozzles and using the pressure differential to jet a portion of the flow within the pipeline through the one or more jetting nozzles onto the inner wall of the pipeline while providing a flow area through the cleaning pig to bypass the portion of the flow which does not pass through the one or more jetting nozzles.

    摘要: A method for the prevention or remediation of flooding waters in a geographic area using one or more thrusters to increase the velocity of a portion of the water in a channel draining the flooding waters away from the geographic area, mixing the portion of the accelerated waters back in to the remainder of the waters in the channel thereby increasing the average velocity of the waters in the drainage system and increasing the rate of removal of the flooding waters from the geographic area, the thrusters having the one or more inlets approximately at ninety degrees from the centerline of the thruster and cleaning the thruster inlets by reversing the flow through the thruster while the flooding waters are still passing the thruster.
