The apparatus comprises a bottom saddle positioner having a support structure on which there are disposed firstly clamping connection means adapted to the diameter of the pipe together with a support adaptor for supporting a bottom saddle, and secondly means for releasably fixing the positioner to the end of the multi-purpose long handle and situated on the side of the support structure opposite from its side on which the clamping connection means are situated.

Abstract: A coupling mechanism for removably connecting a fluid line to an apparatus such as a mass flow controller and includes a flange member for connection to the apparatus so that it is cantilevered from the apparatus and provides a fluid connection with a bore opening that is vertically aligned. A yoke member is dimensioned to extend over the flange member and have a corresponding fluid conduit and bore that can be aligned vertically with the bore opening on the flange member. A seal member can be positioned between the yoke member and the flange member. A spacer member is mounted in the yoke member and a fastener member can be aligned vertically to exert a force on the flange member to apply a sealing pressure to the seal member while locking the yoke member to the flange member.

Abstract: A sealing gasket for a segmented pipe coupling includes radially extending, axially spaced sealing lips interconnected by an axially extending bridge member which has at least one aperture extending through the bridge member in a radial direction, a tubular collar being received within the aperture, the tubular collar being fast with an arcuate elongate plate, the longitudinal edges of which are engaged with mutually presented surfaces of the sealing lips.

Abstract: A tapping sleeve for attaching a branch line to a main fluid conduit. The tapping sleeve has upper and lower sleeve members, bolted together around the main fluid conduit. Shell gaskets seal between the sleeve members and the main fluid conduit and a branch gasket seals around a side opening in the upper sleeve member. Metal shell gasket retaining rings secure the shell gaskets in place and a metal branch gasket retainer secures the branch gasket. In the preferred embodiment, the retainer is a retaining ring. In an alternate embodiment, the branch gasket is secured by a shoulder formed by extruding the upper sleeve member.

Abstract: A clamping device for connecting a branchpipe to a main pipe buried underground, has a main body with a lower side having a curved surface for engaging the main pipe and, at the same time, is provided with a connection port for a branched coupling. Arms are supported by sections of the body on both sides of the connection port cand on the upper side of the main body. These arms are extended downwardly so as to hold the main pipe and move for free rotation with respect to the support sections. Arm retainers are idly supported at the centers by bolts which are screwed into threaded holes provided on a midplane of the support sections of the main body. The retainers have pushing sections formed on both their ends for pushing the arms from above, at external sides of the support sections. Only a small working hole must be excavated for connecting the branched pipe to the main pipe since the clamping device can be positioned and tightened from ground level.

Abstract: The invention provides a junction coupling for branching a flow of fluid from a pipe or conduit. The junction coupling is essentially C-shaped and is dimensioned partly to surround such pipe or conduit. Opposite limbs of the C-shaped member carry, on the one hand, an outlet duct and on the other hand means for securing the coupling in position on the pipe or conduit. The outlet duct is alignable with an aperture in the conduit wall and adapted to receive a branch conduit. The dimensions of the C-shaped member are such that the coupling may be engaged over the pipe or conduit only at the location of the aperture therein.
