Device for locking telescopic tubular elements in terms of translation: France FR 2685742
The invention relates to a device for locking two telescopic tubular elements (1, 2) in terms of translation along their longitudinal axis (1a, 2a), this locking device (7) essentially comprising a lock bolt (12). It is characterized in that: – on the one hand, independently of the lock bolt (12), the internal element (2) at least indirectly bears a stop piece (18) intended to interact with another stop piece (19) for its part borne by the external element (1), which stop pieces (18, 19) are orientated and located so as to define the erect position of the proximal ends (8, 10) of the elements (1, 2), and – on the other hand, the stop surface (17) borne by the external element (1) consists of an essentially planar surface produced in a plane approximately orthogonal to the longitudinal axis (1a) of the said external element and which, at the proximal end in question,; extends over a given angular fraction around the longitudinal axis (1a) of the external element.
Deviating device towards at least a dripping point of a liquid on a longitudinal element: Europe EP 0396443
The invention relates to a device for deviation towards at least one dripping point of a liquid flowing on a long, linear, especially substantially cylindrical, element of a structure. It is characterized in that, on the one hand, it is produced in at least one material (11) which is elastically deformable and, on the other hand, the wall (6) which carries the deviating surface (7) and the said bearing area (10) of the means of fixing exhibits a gap in continuity (12) which extends from the said bearing area (10) of the means of fixing on the outer face of the element out to the outer edge (9) of the said wall in such a way as to permit the long, linear element to pass from the outer edge into the bearing area (10) of the means of fixing.
Foldable radio frequency antenna: France FR 2653598
The invention relates to a foldable radio frequency antenna including a plurality of straight-line elements arranged perpendicular to at least one substantially long, straight support body. It is characterized in that: – the long, straight body (3) of the antenna (1) consists of at least two segments (6, 7) joined by at least one means (8) of articulation at least between an aligned position of these segments, called active position, and a so-called rest position, – at least some of the straight elements (2) of the antenna (1) consist of at least two segments (9), all joined in pairs by at least one means (10) of articulation at least between an aligned position of these segments (9) called active position and a so-called rest position, – at least some of the straight elements (2) form, with the antenna body (3), separate parts joined by at least one means (11); of articulation at least between a so-called active position in which each straight element (2) joined to the body (3) extends substantially perpendicularly to the said body (3) and a so-called rest position.
Device for wind bracing the members of a lattice mast and lattice mast provided with said devices: États-Unis US 4772894
The invention relates to a device for wind bracing of the vertical members of a lattice mast. It is characterized in that it is provided at its ends (5, 6) with detachable means (8, 9) for joining it to its vertical members, which in turn are provided with complementary means (10).
Arm for supporting an overhead conductor wire: France FR 2564044
The invention relates to an arm for supporting an overhead conductor wire for the electrical supply of a moving body. It is characterized in that the body consists of a core (7) of alveolate material and, each covering one of the upper (8) and lower (9) faces of the core (7), of two skins (10, 11) which for their part consist of a composite material obtained by polymerization of technical fabrics impregnated with resins. Application to the industry producing equipment for the electrical supply of moving bodies, and in particular for high-speed trains.
Sealing strip for building window: FR 2769336
The sealing strip (1), made from rubber or elastomer, has a U-shaped cross-section with a base (3) and side walls (4). The base has elongated transverse holes (6) 0.5 – 1.5 mm wide at regular intervals, and the side walls and remaining portions of the base have cut notches (7) joining the ends of the holes, forming zones for cutting the strip to the required length e.g. by inserting a screwdriver tip in the appropriate hole and pulling it.
