    摘要： A method of joining pipes in which a sleeve is placed over the adjacent ends of the pipes so as to overlap each pipe. The sleeve fits with clearance around the pipe ends. The ends of the clearance space are closed by inflating hollow sealing rings and then epoxy resin is injected into the clearance space to fill the space. The pressure of the epoxy resin composition is then raised to a pressure substantially greater than atmospheric and the pressure is maintained until the resin composition is set.

    摘要： Two coaxial metal pipes, whose confronting extremities are each provided with a plurality of peripheral ribs of staggered height separated by two or more peripheral grooves, are interconnected by a coupling sleeve of fiber-reinforced thermosetting resin subdivided into several coaxially interleaved and independently deformable cylindrical shells each terminating in a pair of internal beads engaged in a respective peripheral pipe groove. The shells, increasing in axial tensile strength from the innermost to the outermost one, are preferably separated from one another by interposed antibonding layers of thermoplastic resin. A resinous filler can be inserted between the pipe extremities for electrically insulating them from each other. The shells of the coupling sleeve can be formed by coiling resin-coated filaments around the pipe axis, advantageously with application of an antifriction layer on each inner shell before the thermosetting material thereof has been fully hardened.

    摘要翻译： 两个同轴金属管道，其四面体均设有多个由两个或多个外围槽隔开的交错高度的周向肋，通过纤维增强热固性树脂的连接套筒相互连接，纤维增强热固性树脂细分成多个同轴交错和独立变形的圆柱形壳体 每个终止于啮合在相应的周边管槽中的一对内部珠粒。 优选地，通过插入的热塑性树脂的反粘合层将从最内侧到最外侧的轴向拉伸强度增加的壳分离。 可以在管端之间插入树脂填料以使它们彼此电绝缘。 耦合套筒的壳可以通过围绕管轴线缠绕树脂涂覆的长丝而形成，有利的是在其热固化材料已经完全硬化之前，在每个内壳上施加减摩层。

    摘要： A pipe coupler utilized for connecting two sections of pipe to prevent the escape of gas from within the pipe through the joint therebetween. An annular coupling member comprises two end sections and an intermediate section therebetween, with the two end sections having an inside diameter substantially the same as the outside diameter of the pipe sections, while the inside diameter of the intermediate section is greater. The two pipe sections are disposed within the coupling member, with the joint positioned longitudinally within the intermediate section. The two pipe sections and the intermediate section form an annular space therebetween, and in this annular space is positioned an annular sealing gasket. The sealing gasket has an inside diameter substantially the same as the pipe outside diameter, and has a radially outwardly extension positioned therearound. The intermediate section has a pair of spaced apart openings, and filling plugs are sealingly disposed within these openings, and the plugs extend inwardly into the annular space. The gasket outwardly extension is positioned between the filling plugs. An adhesive sealant is disposed within, and substantially fills the annular space between the gasket and the coupling member. The adhesive sealant, which enters the annular space through the filling plugs, compresses the gasket against the two pipe sections to seal the pipe joint therebetween. Also included are means for preventing the sealant from leaking out of the annular space through the filling plugs.

    摘要翻译： 用于连接两个管段的管连接器，以防止气体从管内通过其间的接头排出。 环形联接构件包括两个端部部分和它们之间的中间部分，两个端部部分具有与管部分的外径基本相同的内径，而中间部分的内径更大。 两个管段设置在联接构件内，其中接头纵向地位于中间区段内。 两个管段和中间部分之间形成环形空间，并且在该环形空间中设置有环形密封垫圈。 密封垫片具有与管外径基本相同的内径，并且在其周围具有径向向外延伸。 中间部分具有一对间隔开的开口，并且填充塞密封地设置在这些开口内，并且塞子向内延伸进入环形空间。 垫圈向外延伸位于填充塞之间。 粘合密封剂设置在垫圈和联接构件之间并基本上填充垫圈和联接构件之间的环形空间。 通过填充塞进入环形空间的粘合剂密封剂将垫圈压靠在两个管部分上以密封其间的管接头。 还包括用于防止密封剂通过填充塞从环形空间泄漏的装置。

    摘要： The structures of the present invention start with a basic hollow tube of any desired outer shape and made of paper, plastic or metal. When paper is used, it is vacuum impregnated with a plastic resin and oven baked to give it rigidity. The tube may also be covered with an ornamental veneer, if desired. The tubes are provided with suitable openings to receive matching counterparts fitting against the openings. Strong, rigid core members of wood, plastic or metal are positioned in the tubular members with the abutting portions of the core members interconnected. The structure is placed in a clamp to hold the parts together in proper position. Polyurethane is then poured into one end, the end is capped, and the structure is rotated to evenly distribute the polyurethane. The urethane sets at room temperature and expands as it sets to internally mold the members into a solid structure. The finished structure can be drilled, machined, or bolted to add features in the conventional manner.
