A conical seal fitting (CSF) has a longitudinal bore between proximal and distal ends, an exterior conical sealing surface near the distal end and an exterior shoulder between the proximal end and the exterior conical sealing surface. A flange has a through-hole defined by an interior conical sealing surface and interior threads. A gland nut surrounds the CSF and has exterior threads that engage the interior threads. The gland nut presses against the exterior shoulder to push the two conical sealing surfaces together to form a seal. The CSF has an O-ring received in a groove and a trapped annular space is defined between the O-ring and the seal. The flange has a test port extending from outside of a vessel into the annular space. The annular space can be pressurized through the test port to test the seal. A tube passes through the bore and is sealed with the CSF using a ferrule and a nut.

A sight glass assembly can comprise a housing defining an inner housing surface, an outer housing surface, a first housing end, and an opposed second housing end, the inner housing surface defining a housing bore; an adapter defining an inner adapter surface, an outer adapter surface, a first adapter end coupled to the housing, and an opposed second adapter end, the inner adapter surface defining an adapter bore, the outer adapter surface defining a central portion disposed between the first adapter end and the second adapter end, the central portion defining a shoulder contacting the second housing end of the housing; and a transparent viewport positioned in the housing bore such that the interior of a pipe fitting is viewable through the housing bore, the transparent viewport, and the adapter bore.

Tubing retainers use with sensors, sensing systems including the tubing retainers, and methods of using the tubing retainers and sensing systems are disclosed.

A fluid level sensor assembly includes a first pipe component defining a flow path for the fluid and configured to be attached to a valve to control flow of the fluid from the first pipe component, and a fluid level sensor arranged in or on the first pipe component to detect a level of fluid in the first pipe component and to generate a command signal for operation of the valve according to the level detected. The assembly also includes an insert fitted to an end of the first pipe component and extending axially from the end to be fitted to an inlet of the valve, in use, wherein the insert is configured to secure the first pipe component against rotation relative to the valve inlet when the insert is fitted to the inlet.

An industrial process field device includes a pressure sensor, and a housing containing the pressure sensor. The housing includes a base having a base interface and a first base process opening. A flange is attached to the base and includes a flange interface having a first flange process opening. A first gasket process opening of a gasket is aligned with the first base process opening and the first flange process opening. A first surface of the gasket engages the base interface, and a second surface of the gasket engages the flange interface. A dielectric insulation system includes at least one dielectric layer that insulates the housing from electrical currents conducted through the flange. Each dielectric layer includes a layer of ceramic material, an anodized layer, or a plastic overmold, which improve a maximum working pressure of the field device.

An interface adapted for connecting a fluid measurement point includes a body including at least two connection locations, wherein the body has fluid ducts, each of which has a connection location, wherein the fluid ducts have at their connection locations first duct axes, wherein the connection locations are especially coplanar, wherein the connection locations are adapted for connecting process connectors from a connection direction for sealed communication with the fluid ducts, wherein the fluid ducts are adapted via the process connectors to supply, and drain, a medium, respectively, to and from the fluid measurement point, wherein the interface has at least one holding element for releasably securing at least one process connector to the body, wherein the holding element has at least one process connector seat, wherein the holding element is adapted to be moved into an end position (EP) effecting the securement.

The present disclosure provides a pressure measuring instrument which comprises a gauge body, a connecting component and a pushing component, the connecting component comprises a first connecting member and a positioning sleeve which are connected with each other to form a corotating relationship, and the first connecting member comprises a first external thread section and a second external thread section connected to each other, and the first external thread section is used for a pressure-measuring hole threaded with a pressure vessel, the second external thread section protrudes from the pressure-measuring hole, the positioning sleeve is rotatably screwed to the second external thread section, and the positioning sleeve is configured to provide a force to the pressure vessel, and the pushing component is configured to pass through the connecting component and be pushed by a fluid in the pressure-measuring hole to push against a pressurize unit of the gauge body.

The disclosure relates to an ex vivo generated population of educated macrophages specific to LPS and methods of making and using such macrophages.

Disclosed is a tube configured to conduct a fluid flowing through the tube in a specified flow direction and for this purpose comprises a tube wall, which encloses a lumen of the tube, and an interference body, which is arranged within the tube but is nevertheless connected to the tube wall at an inner face of the tube wall facing the lumen. In the tube according to the present disclosure, the tube wall has a maximum wall thickness of more than 1 mm and at least two mutually spaced sub-segments with a respective wall thickness that deviates from said maximum wall thickness, wherein the sub-segment is positioned upstream of the interference body in the flow direction, and the sub-segment is positioned downstream of the sub-segment in the flow direction.
