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 seamless tubular liner for repairing an underground or surface pipe is disclosed, including circumferential wefts consisting of slivers comprising a plurality of staple fibers bundled together, the slivers adapted to elongate through disentanglement of the bundled staple fibers when the seamless tubular liner is subjected to an inflation pressure such that the diameter of the tubular liner is able to expand to accommodate variations of diameter of the pipe being repaired.

Abstract: The device comprises at least one pair of flexible ballasts which extend laterally along the length of the inflatable structure and each comprise an orifice, acting as a vent, situated at the front, and a scoop system situated at the rear. Between the ballasts, at least one pipe connects the cavities of said ballasts to equalize their level of fill and the stagnation pressure of the water obtaining in said cavities when the inflatable structure is pulled along in the inflated state. This scoop system consists of a component moulded in a rigid or semirigid thermoplastic or is made of an assembly of cutouts from a flexible material of watertight fabric. This scoop system is bonded and/or welded to the ballast.

Abstract: The rescue device for the passengers and crew of a ship includes: a container that contains survival equipment; a system that is intended for stowing said container relative to the deck of the ship and contains at least one strap and a system for multimodally attaching and releasing said container; an airbag-type inflatable balloon set up between a structure, secured to the deck, and said container, said structure defining a passage for the passengers when needed; and a means for releasing the airbag set up on the wheelhouse of said ship. The frame-shaped structure is formed of: two side posts; a lower cradle, on which said container rests; an upper crosspiece; and a plate set up inside the ship and acting as a counterbearing for the airbag when said container is ejected.

Abstract: The present invention relates to an inflatable marine evacuation slide for evacuating people from a ship to at least one inflatable liferaft (or survival raft), as well as rescue equipment for the passengers and/or crew members of a ship, comprising at least one inflatable liferaft, stored folded in the deflated state, together with associated inflation means, in a container around which is wrapped, folded in the deflated state, an inflatable marine evacuation slide according to the invention.

Abstract: The invention relates to methods and devices for launching into the water, from a height H greater than a predetermined height hmax, a life-saving object designed to be able to be launched into the water in free fall from this maximum height hmax. One end of a halyard is fixedly hooked to the life-saving object or to the launch site; the halyard functionally cooperates respectively with the launch site or the life-saving object so that the life-saving object falling by gravity is braked on and/or by the halyard over at least one part (H-hmax) of its drop height. By controlling the braking effect, the life-saving object, falling from the height H in a braked manner over at least one part (H-hmax) of this height hits the surface of the water (5) with a kinetic energy not exceeding that which it would have at the end of a non-braked free fall from at most the height hmax.

Abstract: The invention relates to a method of cleaning a solid surface comprising the following stages: a) the solid surface is cleaned using a microemulsion-type cleaning composition; e) the cleaned surface is drained; f) the drained surface is rinsed with an organic solvent or a mixture of organic solvents with a low boiling point; and g) said surface which was rinsed with the organic solvent or the mixture of organic solvents used in c) is then dried.
