An insertion probe adapter for fluid sample extraction from a pipeline for mounting of an overlying housing element is illustrated and described. The invention permits disengagement of an insertion probe from the body of the probe adapter without disassembling the body from the pipeline and without disassembling the overlying housing element from the body.

A gas turbine engine comprising a combustion section enshrouded by a casing having at least one through passage, the combustion section comprising a dome wall and a liner at least partially defining a combustion chamber; a fuel nozzle connected to the dome wall and having a nozzle tube; and a coupling securing the fuel nozzle with casing and disposed at least partially in the at least one through passage.

A sprinkler coupling structure, including a reducing nipple configured to penetrate a through hole formed in a ceiling panel and manufactured integrally with a flexible pipe body whose upper side is connected from a water supply source and into which fire extinguishing water flows, a head coupled to a lower end of the reducing nipple and configured to spray the fire extinguishing water supplied from the water supply source through the reducing nipple, a nipple fixing member configured to fix and couple the reducing nipple to the ceiling panel so that a height at which the reducing nipple protrudes from the ceiling panel is adjusted, and a head protection net configured to protect the head from under the ceiling panel.

The present invention describes a tubular scoop that may be utilized with various assemblies for sampling fluid in a pipeline. The scoop includes a bend with a bend radius that is from two to four times the diameter of the scoop. The scoop defines a scoop face that is parallel to an axis of the tubular of the scoop. The scoop is mounted with a threaded connection that seals around the tubular. An additional seal comprises a compression nut that allows orientation of the scoop within the pipeline whereupon the scoop orientation is fixed by tightening the compression nut.

A manifold may include a pipe, a nut member at an outer circumferential surface of the pipe, and a manifold body including a port having a concave shape extending into the manifold body from an outer surface of the manifold body, wherein a first portion the nut member is inserted into the port, and the manifold body including a locking part protruding on the outer surface and engaging with a second portion of the nut member to prevent the nut member inserted into the port from being rotated and loosened.

A system including an annular socket body for tightening a lock ring around a threaded end of a conduit connector extending through an opening in a wall of a junction box is provided. To facilitate capturing of the lock ring by the socket body without interference, the wrench lugs of the socket body each have a circumferential extent that is less than 50% of a circumferential extent between teeth of the lock ring, and there are half as many wrench lugs than teeth. Flat side faces of the wrench lugs are disposed at an angle of between about 15 and 40 relative to sides of the teeth of the lock rings so that the wrench lugs engage the lock ring teeth in a sliding point contact that promotes uniform engagement between the wrench lugs and the lock ring teeth when torque of about 1400 inch-pounds is applied to the socket body.

Provided is a coupling for providing a tap off a main pipe and a method for deploying and manufacturing the same. The coupling includes an insert for partial insertion into the main pipe. The insert includes a coupling pipe for providing a flow conduit and an anchor pivotably connected to the coupling pipe at an insertion end. The anchor is configured to retract when inserted through an opening in the main pipe and deploy to a deployed configuration once inserted. In the deployed configuration the anchor extends radially from the coupling pipe for engaging an interior surface of the main pipe and anchoring the coupling to the main pipe when the insert is drawn outward by a securing force. At least one anchor is sufficiently rigid and fixed from pivoting past the deployed configuration to withstand forces for anchoring the coupling to the main pipe.
