A latching valve has a valve body defining a fluid chamber and supply, delivery, and exhaust ports. A solenoid within the chamber includes a pole piece defining a fluid passage between the chamber and exhaust port and having one end facing the exhaust port and another end defining a first valve seat. A coil is disposed about the pole piece. A housing has a portion radially outward of the coil and portions extending radially inwardly on opposite sides of the coil radially aligned with the pole piece and an armature. The armature has one end configured for engagement with the first valve seat and another end configured for engagement with a second valve seat formed in the valve body between the fluid chamber and supply port. A return spring biases the armature towards the second valve seat. A magnet ring is disposed about the armature in contact with the housing.

A method of forming an electrorheological fluid structure with attached conductor and method of fabrication. A polymeric housing may have a channel defined therein. A first conductive trace may at least partially coincide with the channel. A first wire may have a first conductor surrounded by a first insulating jacket. The first conductor may be in electrical communication with the first conductive trace. A jacket bonding region of the first jacket may be welded to a housing bonding region of the housing. The jacket bonding region and the housing bonding region may be formed from a common type of polymer.

A valve arrangement for a hose end coupler of a transfer hose for the offloading of hydrocarbons from an offshore floating production storage and offloading vessel (FPSO) to a shuttle tanker is described. The valve arrangement comprises a linear valve comprising a linear valve actuator movable between a first position whereat the valve is closed and a second position whereat the valve is open; a secondary valve comprising a secondary valve actuator movable between a first position whereat the valve is closed and a second position whereat the valve is open; the linear valve actuator and the secondary valve actuator are operatively coupled so movement of the linear valve actuator effects a corresponding movement of the secondary valve actuator. A hose end coupler with the valve arrangement, and a transfer hose and transfer system and method incorporating such a hose end coupler with the valve arrangement are also described.

A portable inflation device of the present application includes an inflation pump body, an upper casing, a middle casing, a lower casing, a resilient component, and a resilient ventilation plug. The upper casing and the middle casing respectively seal two ends of the inflation pump body, and an air chamber is defined thereamong. An accommodating chamber is defined between the middle casing and the lower casing disposed outside the air chamber. An intake hole, a first ventilation hole and an exhaustion hole are respectively formed on the upper casing, the middle casing and the lower casing. The resilient ventilation plug disposed inside the accommodating chamber includes a perforated foam positioned between the first ventilation hole and the exhaustion hole and an sealing layer covering a surface of the perforated foam facing towards the first ventilation hole. The inflation device is small in volume, collapsible, portable, and easy to operate.

A component for a target material transfer system for a laser-produced plasma radiation source and a method of manufacturing such a component are disclosed. The component, which may, for example, be a target material transfer line, a freeze valve, or a flow restrictor, or some combination of this functionality, is made up of a glass capillary body sealed with glass-to-metal seals at both of its ends to a respective metal fitting. The method of manufacturing involves heating the ends of the glass capillary and then forming them to conform with, and forming a glass-to-metal seal with, the interior contours of the respective channels in each of the metal fittings.

A monolithic three-dimensional fluidic check device is presented. The monolithic three-dimensional fluidic check device comprises a housing surrounding a fluidic flow path and having a first opening at a first end of the housing and a second opening at a second end of the housing, and an elongated center body positioned within and extending along the fluidic flow path. The elongated center body is stationary relative to a flow of fluid.

An element is deployed within tubing extending to a downhole tool. The downhole tool includes a hydraulic tool and a valve coupled between the conveyance string and the hydraulic tool. The valve includes a valve seat having a passage directing the fluid from the conveyance string to the hydraulic tool. Deploying the element includes landing the element on the valve seat such that the element substantially obstructs flow of the fluid through the valve seat passage. The valve is opened to direct the flow of the fluid around the hydraulic tool, wherein opening the valve utilizes pressure generated in response to the element obstructing the flow of the fluid through the valve seat passage. At least a portion of at least one of the element and the valve seat is then degraded by an amount sufficient to permit the element to pass through the valve seat passage.

A system for a footwear sole component to control an incline in between a footbed and an outsole. An incline adjuster is positioned between the footbed and the outsole. The incline adjuster has a polymeric housing having a first fluid chamber, a second fluid chamber, and a fluid transfer channel; a controller having a processor, a memory, an inertial measurement unit (IMU), and a low energy wireless communication module. The controller determines whether forces from a wearer foot on the first fluid chamber and on the second fluid chamber are creating a pressure within the first fluid chamber that is higher than a pressure within the second fluid chamber, or vice versa.

A mesh valve protection device includes at least one layer of mesh, wherein the mesh valve protection device is adapted to be positioned proximate an inlet of a valve assembly so that a fluid flow controlled by the valve assembly passes through the at least one layer of mesh of the mesh valve protection device before passing through the valve assembly.
