摘要： The present invention relates to a repair sleeve comprising a flexible, hose-like main part (1) and a spiral spring (2), which, when the sleeve is mounted in a pipe line, pretensions the hose-like main part (1) into sealing engagement against the inner wall of the surrounding pipe. The invention also includes an insertion device (4) for the repair sleeve, said device being a cylindrical body (5) mounted on wheels. At the ends of this body (5) there are latching means (7, 8) which are releasably fastenable to the ends of the spring (2). The latching means comprise a pin (7) biased to thrust out through the wall of the body (5) and into holes at the ends of the spring (2) wound round the body (5). Both pins (7) are simultaneously releasable with the aid of a linkage system (11, 13, 14, 15) on actuating the system. Eyes or cages (8) accommodating the ends of the springs are also associated with the pins (7).

摘要： Equipment for closing conduits comprising a closing lid (1) having two circular disks with a peripheral sealing ring of resilient material. A tightening device connect the two disks at the center thereof causing during tightening to compress the sealing ring radially outwardly. The tightening device is of very stable construction conferring to the disks a parallel movement without mutual rotation. The equipment moreover comprises a mounting device (30) having three parts which are mobile in relation to each other, an attachment yoke (31), a main clamp (39) and a support plate (43). With the aid of a cog gear (40) and racks (42, 44) rotary movements are transformed into either a clamping movement between the closing lid (1) and the support plate (43) or a pulling movement between the closing lid (1) and the main clamp (39).

摘要： The present invention relates to a union device for pipe joints, where the joint is within the wall thickness of the pipes being joined, and includes a female part (1) and a male part (2), which in substantially complemental implementation permits the male part (2) to be inserted into the female part (1). In the outer and inner peripheral surfaces of the male and female parts there are grooves (5,11) extending around the periphery such as to form a cavity for a locking ring when the joint has been assembled. In this cavity there is a locking ring having a rhomboid form in cross section with cut away portions at the long sides of the two diametrically opposite acute corners and being of a material which retains its shape with a given resiliency. This locking ring is provided with a through slit or with one or more shorter slits from its large end towards its small end. The locking ring is normally placed in the groove (5) in the female part (1) with the large end facing axially outwards, such that on inserting the male part (2) into the female part (1) the male part (2) causes the locking ring resiliently to move away, such as to regain its original shape once again when the groove (11) in the male part (2) comes opposite the locking ring.
