Abstract:
Some embodiments are directed to a valve made up of a rigid wall and a flap. The flap has a non-perforated flexible and deformable peripheral region situated facing the rigid wall. The rigid wall is perforated by at least one orifice situated facing the peripheral region. The flap is joined to the rigid wall by a non-deformable fixed connection. The peripheral region has a substantially conical shape before mounting with a large base and a small base and an inner face on the inner side of the cone. The peripheral region exhibits a deformation following the pressing of the inner face of the large base against the rigid wall in a assembled position.

Abstract:
A prefabricated cladding assembly (1) for mounting to the outside of buildings (10), said system comprising a cladding panel (2) having a mounting bracket (3) bonded thereto.
Abstract:
The deployable solar tracker system comprises a single-axis solar tracker (1) including a plurality of foldable panel array sections (10, 10a). Each foldable panel array section (10, 10a) comprises a shaft section (11), a plurality of support ribs (12) hinged to the shaft section (11), a plurality of solar panels (13) attached to the support ribs (12) and a handling element (28) attached on top of the shaft section (11). The handling element (28) has one or more handle openings (29, 30) dimensioned for receiving one or more lift members oriented in a transversal direction perpendicular to the shaft section (11). The handle openings (29, 30) of the handling elements (28) of the plurality of the foldable panel array sections (10, 10a) are mutually aligned when the plurality of foldable panel array sections (10, 10a) are arranged in a shipping arrangement.
Abstract:
The present invention relates to a tube having a dispensing head and a flexible skirt. The skirt and the dispensing head include a single wall manufactured in a single injection-molding operation in an injection mold. According to the invention, the wall is made of a material whose base constituent is a high-density polyethylene (HDPE) or a mixture of polymers, at least one of which is a high-density polyethylene representing from 5% to 100% by weight of the polymers constituting the wall. The present invention also relates to a process for manufacturing such a tube.

Abstract:
The invention relates to a system (S) for dispensing a product, comprising a pump (P) with a flexible pumping bellows, a lower-end flexible tubular wall section of which is automatically assembled on a chimney of a rigid end piece by interlocking of two complementary hooks, ensuring a sealed connection by pressing together of two complementary annular surfaces.
Abstract:
Some embodiments are directed to a valve, including a rigid end piece that defines a center; a rod at the center of the end piece defining an axis; and a flap, wherein the flap is in one piece and has a flexible wall situated opposite a free end of the rod, the flexible wall is perforated by an orifice concentric with the end of the rod, the orifice has a contour substantially homothetic with that of the contour of the end of the rod in a plane perpendicular to the axis of the rod, the orifice has a surface below a projected surface of the end of the rod in the plane, the flap is connected to the end piece by a non-deformable fixed connection, and the flexible wall presses against the end of the rod at any point of its surface in contact with the end.
Abstract:
The single axis solar tracking assembly comprises a plurality of spine sections (2) connected to one another by universal joints (10), supporting legs (3) rotatably supporting the spine sections (2) on the ground, a plurality of brackets attached to each spine section (2), a plurality of rib members (4) connected to the brackets, and solar panels (5) secured to the rib members (4). The rib members (4) are moveable between a folded position and a deployed position. An auxiliary shaft is located between adjacent universal joints (10) connected to adjacent spine sections (2). First and second crossed spine hinge axes of the universal joints are arranged so that the spine sections (2) can be fold at right angles to the auxiliary shaft and the spine sections (2) can be fold in a zig zag fashion into a compact storage position in which the solar panels are arranged in adjacent parallel planes.
