    摘要: A floating dock comprising a pair of flotation tanks arranged in parallel side-by-side relation, a plurality of transverse, equispaced double-saddle brackets having a pair of spaced-apart saddles each adapted to receive a flotation tank straddling said tanks along the length of the tanks, and connector means adapted to partially encircle each tank and to seat in a recess between corrugations extending from each saddle for connecting the tanks to the saddle brackets. The flotation tank comprises a cylindrical smooth inner wall and a corrugated outer wall coextensive and concentric with said inner wall defining a plurality of equispaced peripheral annular flotation cells extending along the inner cylindrical wall, and a closure plate at each end of the cylindrical walls connected to the inner and outer walls in a water-tight relationship defining a central flotation cell. The outer corrugated wall has a plurality of peripheral recesses extending circumferentially around said outer wall along the length of the outer wall. The floating dock has longitudinal side planks and a top deck, preferably a wood deck extending between and attached to the longitudinal side planks. The floating dock additionally may include one or more floating finger docks connected to a side of the floating dock perpendicular or parallel thereto.

    摘要: A method and apparatus for fusing a bell connector to the end of a corrugated thermoplastic pipe are disclosed in which an expandable mandrel grips a preformed bell and a pipe support grips a pipe co-axial with the longitudinal axis of the bell. A pipe trimmer for facing the pipe end may be moved into and out of the axis of the pipe if necessary for trimming the pipe end to provide a uniform planar flange face and a heater, combined with a supporting flange, moved sequentially into and out of the axis of the pipe and bell for heating the opposed faces of the trimmed end of the pipe and the end of the bell to a desired fusing temperature. Upon heating of the opposed faces of the bell and the pipe to a predetermined fusing temperature, the said faces of the bell and the pipe are abutted against each other, with the back side of the corrugated pipe flange face fully supported by the supporting flange, i.e. backing ring, at a predetermined pressure for a time sufficient to fuse the bell and pipe together.
