In accordance with embodiments of the invention, a reinforcement and/or lining method is provided, wherein a thermoplastic reinforcement and/or lining element is subject to mechanical energy impact and mechanical pressure by a tool so that reinforcement and/or lining material of the reinforcement and/or lining element is liquefied and pressed into porous material to reinforce the porous material. In embodiments, in at least one axial depth, the reinforcement and/or lining element is segmented as a function of the circumferential angle so that at this axial depth the circumferential wall of the initial opening in first regions is in contact with the reinforcement and/or lining element and in second regions is not in contact with the reinforcement and/or lining element.

Disclosed is a method and apparatus for use in a fusion process for conduit. The method includes the steps of: removably positioning a first terminal edge (18) of a first conduit portion (10) with a first terminal edge (20) of a second conduit portion (12); facing the terminal edges (18, 20) of the first conduit portion (10) and the second conduit portion (12); aligning the terminal edges (18, 20) of the first conduit portion (10) and the second conduit portion (12); melting at least a portion of the terminal edges (18, 20) of the first conduit portion (10) and the second conduit portion (12); engaging the melted terminal edge of the first conduit portion (10) with the melted terminal edge of the second conduit portion (12); maintaining pressure between the engaged terminal edges, thereby creating a fused joint area (22); and removing at least a portion of the resultant external bead (24) extending around the fused joint area (22). A fusion apparatus (14) for employing this method is also disclosed.

The present invention is a polymeric panel system (110, 124, 126) and method for production (1906 - 1960) and use thereof, enabling the rapid construction of a building foundation wall (124, 126) or other structure and in particular a below-grade foundation. The polymeric foundation system (124, 126) includes polymeric wall panels (110) and other components (114, 118, 122) suitable for withstanding lateral and end compression loads. The walls include two parallels faces (310, 320) separated by a series of webs or ribs (330), where the webs and faces of the wall panels may be formed of a similar polymer material such as polyvinyl chloride (PVC). The wall panels and/or other components may be extruded (1810) so as to enable the rapid production of sections of wall panels, where the panels may be cut to length (1818) and then affixed to adjacent panels (1822) to form a foundation wall. The method of affixing adjacent panels may include welding, gluing or other techniques and may be performed on the job site or in a pre-fabrication facility. Furthermore, the wall panels may be co-extruded with an insulating material (350, 1810) inserted in the voids between the parallel faces so as to provide improved thermal performance of the foundation as well.
摘要:
Polytetrafiuoroethyjene (PTFE) composite articles that have a macro textured surface. The composite articles include at least two different PTFE membranes in a layered or stacked configuration. The composite article has a macro textured surface characterized by a plurality of strands raised from the surface of the PTFE membrane. The strands may be formed of either interconnected nodes of PTFE or of at least one nodal mass of PTFE and have a length equal to or greater than about 1.5 mm. The macro textured surface provides a topography to the first PTFE membrane. The composite articles have a bubble point from about 3.0 psi to about 200 psi, a thickness from about 0.01 to about 3.0 mm, and a bulk density from about 0.01 g/cm3 to about 1.0 g/cm 3 .

摘要:
Systems and methods for joining polymeric materials (202, 204, 510, 512) together may use lasers (LB) or broadband infrared heat sources (532). The polymeric materials are arranged in an overlapping manner and then are exposed to the heat producing radiation for a sufficient time to join the polymeric materials together at the overlapped area. Such systems and methods may avoid the need to add an energy absorbing dopant to the materials being joined. Such systems and methods also may be used on transparent materials.
摘要:
Un rollo de película reforzada con dos, o tres, o cuatro o cinco o mas bandas de refuerzo longitudinales y pre-estirada de polietileno lineal mono-orientada de baja densidad (LLDPE), que se estira entre el 30% y el 380% de la longitud original de la película base, dependiendo del producto final que se requiera. El estirado es en la dirección de maquina (DM) a un ritmo de estiramiento controlado en dos etapas. Rebobinando diferencialmente la película se atrapa aire entre las capas del rollo, y forma bordes suaves traslapados alrededor del la orilla del rollo para producir un rollo esponjoso y suave que previene y resiste el daño a las caídas debido a que amortigua los golpes, así como el método de fabricación.
