Patent number: 4143774Abstract: A truck on rails includes a vertically adjustable horizontally extending main beam supported at one end and having a plurality of auxiliary beams semi-circularly arranged thereabout parallel thereto and each connected thereto by a plurality of parallel levers of equal length each having a fulcrum on the main beam, being pivotally connected adjacent an outer end to its respective auxiliary beam, and being operatively connected adjacent an inner end to an actuating rod reciprocable by a hydraulic actuator for adjustment of the auxiliary beams radially of the main beam. The auxiliary beams are provided with rollers for engagement with the inside of a pipe, and those on the uppermost auxiliary beam are driven by a compressed-air motor to compensate for frictional drag imposed by the others on pipe being rotated in continuous production on a pipe making machine. When the pipe is cut to length, the truck transports the cut-off length to a storage or shipping area and returns to support another length being made.Type: GrantFiled: February 4, 1977Date of Patent: March 13, 1979Assignee: Owens-Corning Fiberglas CorporationInventor: Peder U.

Patent number: 4009736Abstract: A sandwich wall for pipes, tanks, and the like fluid confining uses, wherein concentric inner and outer glass fiber reinforced plastic skins or shells are separated from one another by essentially radial ribs integrated into the shells to form a monolithic construction. The ribs are of limited axial extent and are separated from one another by rib forms of substantially greater axial extent, the rib forms functioning essentially as spacers without otherwise materially contributing to the strength or rigidity of the structure. The ribs are composed of essentially the same resinous material as the shells plus a filler, which typically can be chopped glass fiber strands, sand, or other particulate material, glass fiber mat or woven fabric, glass flakes, or mixtures of such materials. The ribs may be either helical and continuous throughout the axial extent of the wall or annular and independent of one another.
