Abstract: A safety valve includes: a valve element; a valve seat that has a gas release hole from which a gas is released and a protrusion that protrudes towards the valve element; and a meltable body that is made of a material capable of being melt at an abnormal high temperature. At a temperature other than the abnormal high temperature, the meltable body limits displacement of the valve element to thereby prevent inflow of the gas towards the gas release hole. At the abnormal high temperature, the meltable body is melt, thereby the valve element is displaced and the gas is released from the gas release hole.

Abstract: Fill level monitoring relates to a method for controlling the fill level of a collecting vessel, wherein the collecting vessel could be filled with a dielectric medium. A fill level is monitored by a monitoring circuit with a measuring capacitor, the capacity of which changes steadily in correlation with the fill level, at least beyond a fill level range of the collecting vessel. The method includes: determining a capacity of the measuring capacitor; determining the quality of the measuring capacitor; determining a permittivity of the dielectric medium on the basis of the quality of the measuring capacitor; determining a fill level of the collecting vessel on the basis of the determined capacity of the measuring capacitor and the permittivity of the dielectric medium; and fill level-dependent drainage of the dielectric medium from the collecting vessel.

Abstract: A system and method of injecting a chemical into a high pressure process stream without pumps or other active components. The system utilizes the differential pressure created by resistive losses of downstream components within a high pressure process stream. A bypass side stream is taken from an upstream pressure location and returned to the downstream side of the resistive inline process component. The chemical solution vessel is pressurized by the higher side of the pressure differential. The solution then passes through a flow controlling capillary tube exiting on the lower pressure differential side into the bypass stream. The high flow rate chemically diluted bypass stream then returns to the process stream at the lower differential process stream tie-in. The chemical solution is isolated from the process water pressuring the vessel by a movable separating device preventing mixing of the two fluids. The vessel can also be pressurized by gas.

Abstract: A sealing member, whose unique manner of movement provides an improvement to a quick-connect valve assembly, for fluid control. A coupling force, required to couple the quick-connect valve assembly, containing the sealing member, is substantially reduced, resulting in an improvement to a typical quick-connect valve assembly (prior-art). The quick-connect valve assembly is comprised of at least a male coupler, a female coupler and the sealing member. During the resultant coupling, the sealing member's features ensure that said sealing member is firstly moved in a rotational manner and then secondly, if desired, in a more typical translational manner. The sealing member design allows backward compatibility with the typical quick connect valve assemblies. This backward compatibility allows a simple one-part replacement of a typical sealing member (prior-art) with said sealing member in order to benefit from this improvement.

Abstract: Temperature-controlled pressure regulators are described. An example temperature-controlled pressure regulator described herein includes a regulator body having a process fluid inlet fluidly coupled to a process fluid outlet via a first passageway and a heat transfer medium inlet to be fluidly coupled to a heat transfer medium outlet via a second passageway, where the heat transfer medium inlet is integrally formed with the regulator body. A heat chamber body is removably coupled to the regulator body to form a chamber between the heat transfer medium inlet and the heat transfer medium outlet. At least a portion of the first passageway is disposed within the chamber, and the chamber is to receive a heat transfer medium via the heat transfer medium inlet to provide heat to the process fluid as the process fluid flows through the chamber via the first passageway, which separates the process fluid from the heat transfer medium.

Abstract: A female coupling member includes a coupling member body having a fluid passage and being configured to receive a male coupling member from a front end thereof, and a valve member disposed in the coupling member body to traverse the fluid passage. The valve member has an opening and is displaceable between an open position and a closed position. In the open position, the valve member communicates between a front end side and a rear end side of the fluid passage through the opening. In the closed position, the opening is located outside the fluid passage to close communication between the front end side and the rear end side of the fluid passage. The valve member has a purge passage configured to communicate with both the front end side of the fluid passage and the atmosphere outside the female coupling member when the valve member is in the closed position.

Abstract: This female quick-coupling element for a quick-connect coupling is able to cooperate with a male coupling element. A control ring is able to move in translation along a longitudinal axis between a first position and a second position. A blocking member prevents translation of the control ring as far as its second position. An element for the elastic return of a piston, integral in transverse movement with the blocking member, to its internal position is mounted in a housing of the first coupling element situated outside the housing of the piston, and fluidically isolated from the fluid-flow conduit. The first coupling element comprises transmission means, disposed between the return element and the piston, to return the piston to its internal position.

These embodiments forgo the need to use of two separate devices, one each to accomplish the tasks to set the set point and to verify the set point. Rather, the apparatus incorporates components that can assume different configurations including a first configuration that facilitates the task for setting the set point and a second configuration that facilitates the task of verifying the set point.

Abstract: Embodiments of the invention are directed to a sulfur trap comprising an inlet, a first chamber, a divider, a second chamber, an outlet, and a float assembly. The float assembly may have many different configurations, but generally comprises a float and plug, is configured to float within liquid sulfur, and is operatively coupled to a seal seat in the divider for sealing and unsealing the first chamber from the second chamber. Generally, only liquid sulfur is allowed to pass from the first chamber into the second chamber. However, the sulfur trap may be configured to allow for pressure relief, such that during an overpressure event the plug and seal seat disengage and allow the liquid-gas mixture to flow into the second chamber to prevent damage within the system. In some embodiments a filter and/or the flow of liquid sulfur is directed to collect debris from the liquid sulfur.
