A bidirectional scoop assembly is shown that is mountable to a pipeline for taking samples from the pipeline. A wafer flange is mounted in said pipeline surrounding the fluid flow through the pipeline. A first tubular is extendable through a first side of the wafer flange to receive a sample from the pipeline. A second tubular is extendable through a second side of the wafer flange to receive a sample from the pipeline. The first tubular and second tubular are positioned adjacent each other whereby at least a portion of a first opening of the first tubular and at least a portion of a second opening of the second tubular are axially aligned or parallel to a flow axis of the pipeline.

A retractable sample scoop is shown that is mountable to a pipeline for taking samples from the pipeline. A retractable mounting mechanism mounts to the pipeline wall. A tubular is extendable into the opening of pipeline and retractable from the pipeline. A first seal creates sealing around the tubular portion with respect to said pipeline while permitting insertion, retraction and rotation of said first tubular portion with respect to said pipeline. A second seal comprises a tubular without threads to pipe connector with threads.

A bi-directional flow scoop system and/or tandem system is mountable to a pipeline operable for receiving and returning a fluid flow from the pipeline. A first tubular is mounted so that the first tubular extends into the pipeline. The scoop end comprises a bend leading to a first face with a first opening for communication with the fluid flow. A second tubular is mounted with a second opening for communication with the fluid flow. The bi-directional scoop is configurable to provide fluid flow in two directions when mounted to the pipeline. In one embodiment, the bi-directional flow scoop system and/or tandem system a flange is provided for separately mounting the first and second tubulars and in another embodiment the second tubular is mounted within the first tubular.

A supply pipe for vehicular gaseous fuel includes a main pipe through which gaseous fuel supplied to an internal combustion engine mounted on a vehicle flows, a sub tank separated from the main pipe, and a coupling member that couples the main pipe with the sub tank, wherein the sub tank is coupled with the main pipe via the coupling member.

Provided is a terminal structure of a high-pressure fuel pipe for a direct injection engine which can prevent stress concentration to a brazed portion between a pipe and a connection part effectively. In the terminal structure of a high-pressure fuel pipe for a direct injection engine where a connection head is brazed to an end of a fuel pipe, the end of the fuel pipe continued to a fuel pipe insertion portion of the connection head is provided with a drawn portion, an outer diameter D1 of the drawn portion to a fuel pipe diameter D satisfies 0.8DD10.9D, and a length L1 of the drawn portion having the outer diameter D1 in a pipe-axial direction from an end of the fuel pipe insertion portion satisfies L10.06D.

A system for producing chemicals, such as, ethylene or gasoline, at high temperature (above 1100 degrees C.) having a feedstock source. The system includes a chemical conversion portion connected with the feedstock source to receive feedstock and convert the feedstock to ethylene or gasoline. The conversion portion includes a coil array and a furnace that heats the feedstock to temperatures in excess of 1100 C. or 1200 C. or even 1250 C. or even 1300 C. or even 1400 C. A method for producing chemicals, such as ethylene or gasoline, at high temperature.

A device for a leakproof air-conditioning fluid circuit. A body includes a conduit having a foot at its base, coupled to a communication orifice in the periphery of a tube. A welding is made between an interior part of the base of the foot and a corresponding part of a tube having an orifice. An internal semi-cylindrical a portion of the base of the foot features, around the discharging conduit, a part in the shape of a skirt, formed by two straight or curved segments which together define a semi-cylindrical cradle in the interior wall of the tube. An orifice comprising a whistle-shaped notch in the back of the tube, comprises two complementary segments.

An electrofusion saddle comprising: a thermoplastic body comprising a flange and optionally a spigot which erects from said flange; and a resistance heating coil including multiple windings, wherein said resistance heating coil is partially embedded in said flange and is partially protruding from said flange, wherein the protrusion is of at least 25% of an average external diameter of said multiple windings.

Provided is a terminal structure of a high-pressure fuel pipe for a direct injection engine which can prevent stress concentration to a brazed portion between a pipe and a connection part effectively. In the terminal structure of a high-pressure fuel pipe for a direct injection engine where a connection head is brazed to an end of a fuel pipe, the end of the fuel pipe continued to a fuel pipe insertion portion of the connection head is provided with a drawn portion, an outer diameter D1 of the drawn portion to a fuel pipe diameter D satisfies 0.8DD10.9D, and a length L1 of the drawn portion having the outer diameter D1 in a pipe-axial direction from an end of the fuel pipe insertion portion satisfies L10.06D.

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.
