Abstract

A method for fabricating a liner for a tubular hose, comprising selecting a combination of functional filaments and filling filaments, the functional filaments being elastic filaments, and combining the functional filaments and the filling filaments, in a ratio selected according to a target radial expansion and compression of the liner, under a selected twisting tension and with a selected twist number; into filler yarns; selecting warp yarns according to a target rigidity in a longitudinal direction of the liner; twisting together a number of the filler yarns into filler threads and the warp yarns into warp threads; and weaving the liner around the hose by interlacing the filler threads and the warp threads.

Abstract

A woven tubular liner comprising an outer surface comprising outer wefts and warps and an inner surface comprising inner wefts and the warps, wherein the inner and outer surfaces are connected by the warps, the outer wefts being protected from an environment inside of the tubular linear and the inner wefts being protected from an environment outside of the tubular liner. The method comprises repeating a weaving unit of continuous outer wefts and continuous inner wefts running uninterrupted along a circumferential direction, woven with continuous warps running along a longitudinal direction, offsetting positions of the warps relative to the wefts in the weaving unit, selectively interlacing outer wefts with the warps, and selectively interlacing inner wefts with the warps.

Abstract

A method for treating water contaminated with hydrophobic and lipophilic molecules, comprising forming an emulsion of the contaminated water with an oil; and separating from the emulsion an oil part charged with a captured amount of the hydrophobic and lipophilic molecules and a treated water part, the treated water having an amount the in hydrophobic and lipophilic molecules reduced by the captured amount of hydrophobic and lipophilic molecules than an initial amount of the hydrophobic and lipophilic molecules in the contaminated water.

Abstract

A drilling apparatus for drilling from inside a conduit having at least one service entrance is described. The drilling apparatus comprises a robot, an elongated flexible appliance having a first end and a second end, the elongated flexible appliance connected to the robot; a rotatable drill head connected to the second end of the elongated flexible appliance, the elongated flexible appliance driven by the robot to extend the rotatable drill head inside the service entrance by at least 8 cm and to retract the rotatable drill head out of the at least one service entrance. The apparatus further comprises means to bend the elongated flexible appliance to orient the drill head connected thereto perpendicular to a longitudinal axis of the conduit.

Abstract

A method of reinforcing existing underground water conduits to resist earthquakes and landslides and a reinforcement structural device adapted for insertion into underground water conduits without having to excavate are disclosed. The reinforcement structural device consists of a seamless woven tubular sheath impregnated with a hardening resin which is adapted for insertion into a network of underground water conduits without the need to excavate. The seamless woven tubular sheath consists of continuous longitudinal fiber warp yarn providing tensile strength along the longitudinal axis of the woven tubular sheath and spiralling circumferential fiber filling yarn providing tensile strength around the wall of the woven tubular sheath.
