摘要： 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. Various methods of making such sandwich wall structures are also disclosed.
摘要翻译：用于管道，罐等的夹层壁流体限制使用，其中同心的内玻璃纤维增强塑料外壳或外壳通过基本上径向的肋条彼此分离，整体形成一体式结构。肋的轴向范围是有限的，并且通过基本上更大的轴向范围的肋形式彼此分离，肋形成基本上作为间隔件，而在其他方面实质上不利于结构的强度或刚度。这些肋由基本上与壳体相同的树脂材料加上填料组成，其通常可以是切碎的玻璃纤维束，砂或其它颗粒材料，玻璃纤维垫或机织织物，玻璃薄片或这些材料的混合物。肋可以是在壁的整个轴向范围内是螺旋的和连续的，并且是相互独立的。还公开了制造这种夹心壁结构的各种方法。

摘要： A preformed manhole suitable for use underground is made of reinforced plastic. The manhole comprises a dome section integrally joined at one end of a tubular body by an endless band of reinforced plastic. The dome is arcuately shaped to provide resistance to buckling, and in one specific embodiment is generally hemispherical. The dome includes a manway and a load bearing shoulder for supporting the manhole cover and frame. An upwardly extending rib or collar is provided around the manway to provide additional stiffness and stability.The method for making the preformed manhole is also disclosed. The tubular body is made by applying resin, glass fiber reinforcement, and particulate filler on an endlessly advancing mandrel. The dome is made by applying resin and glass fibers on the surface of a rotating mold. The dome and body are joined by laying-up resin and glass over their mated ends.

摘要： Large volume tubular structures, particularly such structures made of reinforced plastic, are slit longitudinally and convolutely coiled to effectively reduce their volume for shipping, handling, or storing. For further volume reducing advantage a plurality of such tubular structures are coiled together in a shippable package. The slit tubes are subsequently reunited or joined together with other tubes for a variety of end uses.
摘要翻译：大体积的管状结构，特别是这种由增强塑料制成的结构，被纵向地切开并卷绕成卷绕，以便有效地减小其运输，处理或储存的体积。为了进一步减小体积的优点，多个这样的管状结构在可运输包装中卷绕在一起。缝合管随后重新连接或与其他管连接在一起用于各种最终用途。
