Abstract: A formed pipe end-section of a pipeline for connecting the pipeline at an end includes: an annular bead with a first abutment face facing away from the end of the pipeline and a second abutment face facing towards the end of the pipeline; a chamfer reducing a diameter of the pipe end-section from the annular bead towards the end of the pipeline; and a radial recess for accommodating a sealing ring. The chamfer extends at least between the annular bead and the radial recess.

Abstract: A hydraulic hose includes: an innermost layer tube encircling at least one channel. The innermost layer tube has a self-sealing material composition including an elastomeric material and a polyalkyleneimine. In an embodiment, the polyalkyleneimine is selected from polyethyleneimine, polypropyleneimine, polybutyleneimine, and polypentyleneimine. In an embodiment, the polyalkyleneimine is linear or branched.

Abstract: A lock-up clutch for a fluid coupling has a rotating casing having a radial wall which is releasably coupled by the clutch to a piston. The wall is in a fixed axial position; the piston is arranged for relative axial displacement and is coupled to the wall by tongues. Fastening shanks extend through holes in the piston and holes through the ends of the tongues. A friction wedge is interposed between each tongue and the piston, thus preventing radial displacement of the tongue with respect to the piston after the piston has been secured on the fastening shanks (by means of fastening sleeves).
