摘要： A syringe (1) comprises a barrel (2), a stopper (3) and a plunger (4). The barrel (2) has a hollow interior, an orifice (21) and an opening (22) opposite to the orifice (21). The stopper (3) is arranged in the hollow interior of the barrel (2) thereby defining a sealed chamber (5) in the interior of the barrel (2). The stopper (3) is displaceable in the interior of the barrel (2) thereby varying a volume of the chamber (5). The plunger (4) extends through the opening (22) of the barrel (2) into the hollow interior of the barrel (2). The plunger (4) has a distal end (41) outside of the barrel (2) and a proximal end (42) inside the hollow interior of the barrel (2). The stopper (3) has a distal face (31) directed towards the plunger (4), a proximal face (32) directed towards the chamber (5) and an internal cavity (33) opening at the distal face (31). The syringe (1) is equipped with a sealing structure sealing the cavity (33) of the stopper (3) such that the cavity (33) of the stopper (3) is microbiologically sealed.

摘要： An apparatus, method and system are set forth for detection of fluids using Bragg grating sensors, wherein the Bragg grating sensing element comprises an optical fiber having a Bragg grating inscribed therein characterized by optical properties that are dependent upon the periodicity and effective refractive index of the grating, and a package for subjecting the Bragg grating to a change in strain when contacted by a fluid such that periodicity and effective refractive index of the grating changes, whereby when interrogated with laser light any such change in periodicity and effective refractive index may be detected.

摘要： A thermowell assembly (110) is provided for use in measuring a temperature of a process fluid (106). The thermowell assembly (110) includes an elongate thermowell body (120) which is configured to mount to a process vessel (104) and extend into the process fluid (106) contained in the process vessel (104). An elongate bore (140) extends along a length of the elongate thermowell body (120) from a proximal end (142) of the elongate thermowell body (120) proximate a wall of the process vessel to a sealed distal end (144) of the elongate thermowell body (110) positioned in the process fluid (106). A side bore (150) extends from an exterior of the thermowell assembly (110) to the elongate bore (140). The side bore (150) is positioned outside of the process vessel (104). A verification valve (124) includes an inlet (152) coupled to the side bore (150) at the exterior of the thermowell assembly (110) and further includes an outlet (154). The verification valve (124) allows an operator to verify a presence of process fluid (106) in the elongate bore (140) by opening the verification valve (124) and observing process fluid (106) at the outlet (154) of the verification valve (124).

摘要： The present invention relates to an assembly of an end-fitting and an unbonded flexible pipe for offshore transport of oil and gas, where the unbonded flexible pipe comprises from the inside and out an internal pressure sheath, at least one metallic armour layer and an outer sheath such that the internal pressure sheath and the outer sheath form an annulus in which the at least one metallic armour layer is located. The unbonded flexible pipe is terminated in the end-fitting, and the end-fitting comprises a channel connecting the annulus and a cavity, where the cavity comprises a specimen and a window allowing inspection of the cavity from ambient. The invention also relates to a method for detecting water in an annulus of an unbonded flexible pipe.

摘要： A system to mitigate false trips of a valve that supplies water to a piping system in a fire suppression system includes at least one edge device, a control circuit, and at least one user device. The at least one edge device monitors a parameter corresponding to at least one of a corrosion, a presence of water, a differential pressure across the valve, and a temperature in the piping system of the fire suppression system. The control circuit includes one or more processors and a memory storing instructions that, when executed by the one or more processors, cause the control circuit to receive an indication of the parameter monitored by the at least one edge device, predict whether a valve tripping event is expected to occur based on the received indication, and in response to predicting that the valve tripping event is expected to occur, provide the prediction that the valve tripping event can occur for remedial action. The at least one user device presents display data regarding the prediction.
