A fluid monitoring module includes an enclosure, a fluid sensing device assembled with the enclosure, and a controller disposed within the enclosure. The fluid sensing device includes a body member defining a fluid port external to the enclosure and a male threaded sensor port mounted to the enclosure and extending laterally into the enclosure, a female threaded nut assembled with the sensor port, a fluid sensor seated against a counterbore portion of the sensor port, and a retaining collar having a neck portion extending into the sensor port in engagement with the fluid sensor and a head portion captured between the female threaded nut and an end face of the sensor port. The controller is in circuit communication with the fluid sensor for receiving at least one of pressure indicating signals and temperature indicating signals from the fluid sensor, and for measuring fluid data based on the received signals.

A treated additive manufactured article is disclosed. The article comprises a shaped metal alloy having a treated surface layer and a core. At least one of the average hardness of the treated surface layer is greater than the average hardness of the core, and the average corrosion resistance of the treated surface layer is greater than the average corrosion resistance of the core.

An actuated valve system includes a valve including a flow controlling valve element, an actuator assembled with the valve and including an inlet port in fluid communication with a fluid driven actuator member operatively connected with the valve element and movable from a normal position to an actuated position in response to pressurization of the inlet port to at least a minimum actuating pressure, a pilot valve operable to supply pressurized fluid to the actuator inlet port in a first position and to exhaust pressurized fluid from the actuator inlet port through an exhaust port in the pilot valve in a second position, and a backpressure arrangement in fluid communication with the actuator inlet port to retain a positive pressure smaller than the minimum actuating pressure against the actuator member when the pilot valve is moved to the second position.

A check valve includes a valve element and a valve body having a body housing, an annular valve seat insert, a bushing, and a biasing member. The body housing includes an outer circumferential wall extending between an inlet port and an outlet port to define a valve cavity therebetween. The valve seat insert is seated in a body seat surface surrounding the inlet port. The bushing is disposed in the valve cavity and defines a central bore, with the bushing including an outboard end surface axially engageable with the valve seat insert. The biasing member is disposed between a bearing portion of the body housing and an inboard end of the bushing to allow for axial movement of the bushing with respect to the body seat surface. The valve element extends through the bushing central bore and is movable between a closed position and an open position.

In a method for analyzing a material component of a liquid sample, pressurized gas and a liquid sample are supplied to a collection chamber, and the pressurized gas and the liquid sample are heated to an extraction temperature. The liquid sample is sparged with the pressurized gas to vaporize the material component from the liquid sample into the pressurized gas to form a sample gas. A mixture of the liquid sample, the pressurized gas, and the sample gas is discharged from the collection chamber. A pressure of the sample gas is reduced to bring the sample gas into an unsaturated state. The reduced pressure sample gas is conveyed to an analyzer. The pressurized gas is separated from the mixture and conveyed to a bleed port, and the liquid sample is conveyed to a drain port.

A method for low-temperature interstitial case formation on a self-passivating metal workpiece includes exposing the workpiece in a heated gaseous environment comprising oxygen to pyrolysis products of a nonpolymeric reagent comprising nitrogen and carbon.

A spring return cartridge for a rotary actuated valve includes a torsion spring having a spring-loaded intermediate portion extending between first and second end portions and a spring carrier sleeved with the torsion spring. The spring carrier includes a first portion rotationally fixed with the first end portion of the torsion spring, and a second portion rotatably coupled with the second end portion of the torsion spring, such that the second end portion of the torsion spring is rotatable with respect to the spring carrier, and with respect to the first end portion of the torsion spring, between first and second rotational limit positions, with the intermediate portion of the torsion spring biasing the torsion spring second end portion to the first rotational limit position and maintaining a spring-loaded condition in the first rotational limit position.

A hose assembly includes an inner tube, a connector, a collar, and an outer metal conduit. The connector includes a stem portion inserted into a distal end of the inner tube and a body portion extending radially outward and axially rearward of the stem portion. The collar is substantially coaxial with and surrounds the distal end of the inner tube, with the collar being in radial compression against the inner tube. The outer metal conduit is substantially coaxial with and surrounds the inner tube and the collar, with the outer metal conduit terminating at a distal end welded to the body portion of the connector.
