When a bridge pier is reinforced or repaired by wrapping a reinforcement around the pier, a waterproof sheet having a sufficient flexibility to attach to and cover the interface between the pier and the reinforcement in a liquid-tight manner is useful. The waterproof sheet is attached to the interface between the pier and the reinforcement to prevent water from penetrating into the interface for thereby preventing the reinforcement from deterioration.

Liquidproof seams are formed between laminates, most preferably those having a complex textile structure on the sealing side of the laminate, where at least a portion of the complex textile in the sealing region is removed, such as by skiving, to reduce the thickness in the seam, or sealing region, prior to the creation of a durably sealed liquidproof seam.

摘要:
A parenteral liquid administration set which is readily changeable between delivering liquid at measured ''''rate'''' through a drip chamber that has a constant liquid level, and delivering liquid from the chamber in a measured ''''volume'''' with a progressively lowering liquid level. A valve system on a top of an enlarged semi-rigid measuring chamber functions to selectively change between ''''rate'''' and ''''volume'''' delivery. In one version there is also a secondary drip chamber below the enlarged semirigid measuring chamber so the set can simultaneously indicate ''''rate'''' and ''''volume'''' delivery.

A process of manufacturing a waterproof enclosure and sealing the waterproof enclosure includes the steps of forming a rectangular waterproof upper member and a rectangular waterproof lower member; forming four rectangular adhesive members; securing the adhesive members to the lower member by pressing and heating; securing three edges of the upper member to the lower member by pressing and heating to form a partially open enclosure having an open edge; punching a plurality of positioning holes on a periphery of the partially open enclosure; placing an article in the partially open enclosure by inserting the article through the open edge of the partially open enclosure; sealing the open edge of the partially open enclosure by pressing and heating to form a sealed enclosure; and cutting the periphery having the positioning holes to finish a waterproof enclosure.

Provided herein are waterproof fabrics that include a base fabric having a body-facing surface and an outward-facing surface, and a hydrophobic, waterproof barrier disposed on the outward-facing surface of the base fabric, a seam through the waterproof fabric, and a waterproof tape disposed on an outward-facing surface of the hydrophobic, waterproof barrier and aligned to seal the seam against water ingress. The base fabric may be a wicking fabric or may be treated with a compound that enhances wicking, and the hydrophobic, waterproof barrier may include a plastic polymer, polyurethane, polyethylene, and/or polytetrafluoroethylene. The waterproof fabrics also may include an abrasion-resistant coating and/or a durable water repellant (DWR) agent disposed on an outward-facing surface of the hydrophobic, waterproof barrier, and one or both of the abrasion-resistant coating and/or DWR agent may be discontinuous. Also provided are methods of making a waterproof fabric.
摘要:
A geomembrane liner for a containment system including liner panels and connected by a seam at overlapped edges, with the top panel having a conductive lower surface which is non-conductive across the seam. Heat welding of the seams is accomplished by a welder having a heating unit with a projection which interrupts the conductive lower surface of the top panel before forming the seam. Such seams may be used separately or selectively with a lined containment system having a plurality of liner panels covering at least a portion of the containment system bottom. The liner panels have a conductive lower surface and overlap with adjacent panels, and conductive members underlie adjacent panels and contact the conductive lower surface of both adjacent panels to provide an electrical connection between the conductive lower surfaces of the adjacent panels.

Provided herein are ecologically friendly waterproof fabrics that include a base fabric having a body-facing surface and an outward-facing surface, and a hydrophobic, waterproof barrier disposed on the outward-facing surface of the base fabric. The base fabric may be a wicking fabric or may be treated with a compound that enhances wicking, and the hydrophobic, waterproof barrier may include a plastic polymer, polyurethane, polyethylene, and/or polytetrafluoroethylene. The waterproof fabrics also may include an abrasion-resistant coating and/or a PFC-free durable water repellant (DWR) agent disposed on an outward-facing surface of the hydrophobic, waterproof barrier, and one or both of the abrasion-resistant coating and/or PFC-free DWR agent may be discontinuous. Also provided are methods of making a waterproof fabric.
