Abstract: Apparatus and method for mechanically attached connections of conduits may include a conduit gripping member, a drive member, and a seal member, the drive member causing axial movement of the conduit gripping member to indent into an outer surface of the conduit when the assembly is pulled-up, the drive member causing the seal member to form a zero clearance seal at a location that is axially spaced from the conduit gripping member. The zero clearance seal may comprise a face seal arrangement including a gasket, and the conduit gripping member may be a ferrule, ring or other device that can grip and optionally seal against the conduit outer surface. The assembly may include a sensing function for detecting or sensing a characteristic or condition of an assembly component or the fluid or both. In one embodiment, a body coupling member has a two piece construction of a main body and a conduit socket insert. A flared fitting embodiment is also provided.

Abstract: A purging arrangement for a welding system uses automatic flow control function, such as an MFC, to control purge gas flow rate and/or pressure at the weld site.

Abstract: Mechanically attached connections for conduits may include a conduit gripping member and first and second connection members. The first and second connection members may be, for example, a nut member and a body member where the connection members cause axial movement of the conduit gripping member to grip and seal the conduit when the assembly is pulled-up. The mechanically attached connection may include a sensing function for detecting or sensing a condition or characteristic of at least one of the following: the mechanically attached connection, one or more of the connection members, the fluid contained by the mechanically attached connection, or a combination thereof. The sensing function may be, for example, a sensor that is integrated with at least one of the nut member and the body member.

Abstract: Apparatus and method for determining relative and/or absolute axial position of a conduit end within a fluid coupling includes application of input ultrasonic energy in the form of transient shear waves and analyzing the reflected energy. Application of the input energy collected at different radial positions about a first axial location is used with wavelet based correlation techniques to better analyze the reflected energy signals. Quality of the abutment between the conduit end and a surface associated with the coupling may also be determined as a separate or combined feature of the axial position determination.

Abstract: Diaphragm position sensing and movement sensing for diaphragm valves is realized with one or more sensors that are directly disposed with the diaphragm or directly sense the diaphragm itself rather than an associated part of a valve. The invention contemplates many different types of sensors and also temperature compensation.

Abstract: Low voltage logic circuitry is used to permit an entire subsystem of an industrial controller to be placed within a hazardous environment to receive a high speed serial link and undertake the control of multiple control points without expensive and awkward long cable runs and electrically isolating circuits for each cable run. Energy and bandwidth limiting on the high speed link allows power levels commensurate with high data rates yet intrinsic safety of the media allowing it to freely pass in and out of the hazardous area. A mixture of intrinsically safe and non-intrinsically safe equipment on the same logical rack is allowed through a bus isolator providing isolated data communication in backplane fashion between modules while wholly isolating power transmission along the backplane.
