    摘要： A coupling for engagement with the outer surface of a polymeric pipe, having a sub-assembly of a compression sleeve (24), a resilient gasket ring (18) permanently attached to the inner end of the compression sleeve (24), a gripping member (25), and a nut (30). The gasket ring (18) encounters an abutment in a socket (17) in the body (12) as the nut (30) is tightened, and further tightening of the nut (30) radially compresses the gripping member (25) so that its inwardly directed barbed projections (26) engage the outer surface of a pipe (11) to which the coupling is attached. The end of pipe (11) is freely insertable through the gripping member (25) and sleeve (24), and into the socket (17) in the body (12). There are also provided abutment surfaces within the body of the coupling and the nut which abut inner and outer surfaces (34, 35) of a flange outstanding from the outer end of the compression sleeve (24). Also disclosed is an embodiment with a transition spigot (46) having a barbed tail inserted into an end of a pipe enabling the coupling to accommodate a range of similar but different diameter pipes.

    摘要： The proposed finishing tool for the precision machining of holes consists of a chuck unit, a driving head and an interchangeable cutting element with at least three blades spaced around its circumference and connected to their supporting shaft. The cylindrical supporting shaft (9) of the cutting element (10) is provided with a drive pin (14) which projects from the supporting shaft (9) on at least one side; the tubular wall of the driving head (7) of the shaft (4) is provided with at least one support groove (15) and the side faces (17) of the support grooves (15) together with the surface lines of the cylindrical hollow space (8) enclose an angle of between 75 and 105°.

    摘要： A rim space (20) sealing device comprising a peripheral sealing ring of over-lapped shoe segments (36) attached to a floating cover within a storage tank (22). Spring loaded hanger-pushers (68) and horizontal springs (74) keep the peripheral sealing ring of shoe segments (36) pressed against the tank wall (22) and also keep the floating cover (24) centered within the tank (22). The space (20) between the peripheral sealing ring of shoe segments (36) and the floating cover (24) is covered by a flexible fabric (94) that prevents products loss. Vertical movement of the individual shoe segments (36) over each other is prevented by a series of circumferentially arranged rods (82). The over-lap of the shoe segments (36) is restricted by a series of bars (44) forming expansion-contraction spaces (48).
