Abstract: A seal for a blind shear ram is configured to extend between a first carrier and a second carrier of the blind shear ram. The seal includes a curved portion and an elastic layer extending through the curved portion. The elastic layer is configured to contact at least one of the first carrier and the second carrier to seal a wellbore when the first carrier and the second carrier are in a closed position. The elastic layer has a first elasticity. The seal also includes an anti-extrusion structure coupled to the elastic layer. The anti-extrusion structure extends through the curved portion. The anti-extrusion structure has a second elasticity less than the first elasticity. The anti-extrusion structure defines a plurality of slits to facilitate the anti-extrusion structure extending through the curved portion.

Abstract: Various embodiments include gas turbine seals and methods of forming such seals for advanced gas path (AGP) heat transfer designed gas turbine engines. In some cases, a turbine includes: a first arcuate component adjacent to a second arcuate component, each arcuate component formed of a ceramic matrix composite and including a seal slot located in an end face, each seal slot having a plurality of axial surfaces and radially facing surfaces extending from opposite ends of the axial surfaces and an overhanging seal assembly disposed in the seal slot. The overhanging seal assembly including an intersegment seal including a plurality of seal segments defining two vertical seal segments and a plurality of horizontal seal segments and a first overhanging positioner shim seal and a second overhanging positioner shim seal, each including an extended portion. The overhanging seal assembly disposed in the seal slot so as to provide position constrainment of the two vertical seal segments.

Abstract: A seal for a blind shear ram is configured to extend between a first carrier and a second carrier of the blind shear ram. The seal includes an outer layer configured to contact at least one of the first carrier and the second carrier to seal a wellbore when the blind shear ram is in a closed position. The outer layer has a first stiffness. The seal also includes an inner layer spaced from the outer layer. The inner layer has a second stiffness. The seal further includes an anti-extrusion structure extending between the inner layer and the outer layer. The anti-extrusion structure has a third stiffness greater than the first stiffness and the second stiffness. The outer layer covers the anti-extrusion structure.

Abstract: Various embodiments include gas turbine seals and methods of forming such seals. In some cases, a turbine includes: a first arcuate component adjacent to a second arcuate component, each arcuate component including one or more slots having a seal assembly disposed therein. The seal assembly including an intersegment seal including a plurality of seal segments defining one or more end regions. One or more of the plurality of seal segments including at the one or more end regions a plurality of jet holes and a channel having a wire disposed therein, wherein the intersegment seal provides sealing of one or more end gaps defined proximate the one or more end regions in response to the thrust of a flow of pressurized air through the plurality of jet holes.

Abstract: A hydraulic actuator for a downhole pump system includes a piston housing having a head end and a base end. A drive piston is movable within the piston housing between a first piston position proximate to the head end and a second piston position proximate to the base end. The hydraulic actuator includes a control valve that translates between a first control valve position in which fluid is directed into the base end and a second control valve position in which fluid is directed into the head. When the piston moves to the first piston position, a mechanical positon feedback system translates the control valve from the first control valve position to the second control valve position. When the piston moves to the second piston position, the mechanical positon feedback system translates the control valve from the second control valve position to the first control valve position.
