A heating element is configured to provide heat to the injectable medium in the pressure cell. A pressure gauge is configured to measure pressure inside the pressure cell. A temperature gauge is configured to measure temperature in the pressure cell. A top is configured to provide a pressure resistant lid on the pressure cell. A coaxial resonator system is configured to capture microwave measurements of the sample at different temperatures and pressures after the sample is placed inside of the pressure cell, a top of the pressure cell is closed, and after the injectable medium is injected into the pressure cell in the gap.

The single-action emergency thermal valve comprises a body with a through channel for coolant supply through its inlet in the direction of its outlet, and a fuse link in the through channel of the body; the fuse link consists of at least two parts, each of the two parts completely overlaps the section of the through channel, the parts are made of materials with different melting points, and are located in the through channel in series with the increase of the melting temperature of each successive part in the direction from the through channel inlet to its outlet, wherein the body can have transverse ribs and/or transverse ridges at the location of the fuse link.

One or more techniques and/or systems are disclosed for interrupting fluid flow when experiencing fuel leaking conditions, such as an out of specification connection between the fuel source and a device utilizing the fluid. A distal end of a valve body has interfaces with at least a portion of a connection to a fluid supply; and a proximal end interfaces with at least a portion of a fuel intake. An internal passage runs between the proximal end and distal ends of. A displacement member in the internal passage comprises a distal portion that extends out of the valve to engage a valve to the fuel supply. A retention cap selectably engaged with the valve body can comprise a material that deforms under force at a predetermined temperature, resulting in a release of the displacement member under a biasing force form a biasing component between the cap and displacement member.

A pressure relief valve may comprise a housing, a disk, and a seal. The disk may be configured to deflect relative to the housing. The seal may form a sealing interface with at least one of the housing or disk. The pressure relief valve may be coupled to an inflatable slide or an aspirator.

The present disclosure is directed to an apparatus. The apparatus can include a first conduit coupled with the battery pack. The apparatus can include a first valve coupled with the first conduit. The first valve can allow gas to pass from the battery pack through the first valve at a first pressure. The apparatus can include a second valve coupled with the first conduit and with a second conduit. The second valve can allow the gas to pass at a second pressure. The second pressure can be greater than the first pressure. The apparatus can include a noise generating element coupled with the second conduit. The noise generating element can activate based on the second pressure.

Please replace the originally filed abstract with the substitute abstract provided below. A temperature and pressure relief valve apparatus including a body having a first conduit connected to a water heater and a second conduit connected to a discharge pipe. A valve member, positioned between the first and second conduits, is normally biased closed to prevent flow between the conduits. The valve member is configured such that when a temperature or pressure within the water heater exceeds a predetermined level, the valve member opens to relieve pressure and, in turn, water is released through the second conduit. A sensor is disposed about the second conduit and coupled to a controller. The controller measures a capacitance value of the second conduit, detects a change in the capacitance value indicating a presence of water in the second conduit, and asserts an alarm condition upon detection of the change in the second conduit capacitance value.

A packing system is disclosed for use with a valve having a bonnet and a flow passage extending between an inlet and an outlet of a valve body. A bore can extend through the bonnet to receive a stem that moves a control member to control flow through the flow passage. A first packing arrangement can be arranged in the bore about a first portion of the stem. A second packing arrangement can be arranged in the bore about a second portion of the stem with the first packing arrangement between the second packing arrangement and the valve body. A bore port can extend through the bonnet and open into an inter-packing volume of the bore between the first and second packing arrangements and can provide fluid communication between the inter-packing volume and the outlet of the valve or other lower pressure area.

In an embodiment, a system comprises a valve disc configured in an overpressure protection device. The system can also include a valve gasket configured to rest on the valve disc. The system also includes a valve seat configured above the valve gasket, wherein the valve gasket is sealed in between the valve seat and the valve disc. The system further includes a supporting structure configured above the valve seat. The supporting structure is configured to enable the valve gasket to remain in position between the valve disc and the valve seat in response to an increase in pressure.
