A pipe fitting placement system includes a fitting holder including a bar defining a fitting bore proximate to a first end of the bar, the bar further defining a second end distal from the first end, the bar being elongated in a longitudinal direction extending from the first end to the second end; and a saddle coupled to the bar proximate to the second end of the bar, the saddle rotatable about a saddle pivot axis with respect to the bar; and a pipe fitting received within the fitting bore of the fitting holder.

A retractable fitting with a stopcock has a stopcock housing for connection to a pipe or process chamber. The housing has a connection opening into the pipe or process chamber. A shut-off body is rotatable about a pivot axis relative to the stopcock housing, and has a passage hole that merges in an open state of the stopcock into the connection opening of the stopcock housing, the connection opening being closed by the shut-off body in a closed state. A support element in the passage hole is introduced in the open state through the connection opening into the pipe or process chamber. A plurality of flushing lines are operable to conduct a flushing medium, the plurality of flushing lines being accessible from outside of the stopcock and being connected to and/or opening into the passage hole of the shut-off body at least in the closed state of the stopcock.

An assembly for sealing an interface between a conduit and a case includes a boot and a bushing. The boot includes a tube and rubber flange. The rubber flange extends generally radially outward from the tube. The rubber flange includes an opening passing through a portion of the rubber flange. The bushing is disposed in the rubber flange and includes a tubular body, a channel, and a lip. The tubular body is disposed in the opening of the rubber flange. The channel extends through a center of the body. The lip is generally flat and extends radially outward from the tubular body. The lip is in contact and engages with the rubber flange so as to compress the rubber flange against the case.

A ball and socket coupling that avoids threaded tightening-components instead has telescoped components that are bonded together. Such a coupling has a hollow seat-formed link, a counterpart hollow ball-formed link, and a socket-forming collar. Both the links have fitting extensions. The ball-formed link has a spherical bulb at one end as the seat-formed link has a conforming, spherically-widening seat surface at one end. The socket-forming collar has a centrally apertured web with a conforming spherically-narrowing socket surface at one end of an axially elongated sleeve. The coupling is adapted to be assembled and bonded into solid rigidity by workers in the field with the spherical bulb bonded to and clamped between the seat-formed link's spherically-widening seat surface and the collar's spherically-narrowing socket surface. In addition, the collar's elongated sleeve is bonded internally to the seat-an outer sidewall of the seat-formed link's seat-formed end.

A cutting machine waste extraction apparatus is provided for a cutting machine that cuts a plate where the cutting machine waste extraction apparatus is supported adjacent a cutting area at a cutting table. The cutting machine produces waste at the cutting area during the cutting of the plate where the apparatus includes a ducting system having a first duct that receives the waste from the plate, and a second duct that receives the waste from the first duct. The first duct is movable along the length of the second duct and the second duct includes a lengthwise opening which is sealed by a flexible belt. The flexible belt is deformable from sealed contact with the second duct, adjacent a junction apparatus, where the junction apparatus provides a fluid connection between the first duct and the second duct.
