The invention relates to a method of producing a winding (1), e.g. for an electrical transformer, from a cylindrical, tubular metal element having a straight polygonal section. The inventive method is characterised in that it comprises the following steps consisting in: machining a series of essentially-parallel cuts through all of the sides (1a, 1c, 1d) of the tubular element excluding one last side (1b), said step being performed in a first series of passes; and, in a second series of passes, machining cuts in the aforementioned last side (1b) in order to form a junction with the cuts in the adjoining sides, such that said cuts are continuous and form a single helicoidal groove.

The invention concerns a system (1) for the security of passengers boarding a means of transport (4) such as an aircraft or any other means of land or water transport, said boarding being carried out inside a single secure site (2), characterized in that said secure site (2) comprises at least one access means (5) equipped with control means (6), enabling those concerned by the transport, namely the passengers and the administrative, technical and crew personnel to be securely identified, said secure site (2) being equipped with one or more of said control means (6), arranged at strategic locations, enabling said involved persons to be followed from the time of their access to said secure site (2) until their boarding said means of transport (4), as long as said means of transport (4) is not moving, said secure site (2) being equipped with at least one secure opening (10) enabling at least part of said means of transport (4
摘要:
The invention relates to a method for securely transporting value documents and objects (2) from a departure site to a destination site, in particular means of payment, banknotes, cheques or bankcards locked in a container (4) which causes the degradation thereof by appropriate means in the case of breaking or attempt of breaking. The inventive method makes it possible to send said value documents or objects (2) from a sender (10) to a consignee (30) by means of at least one security guard (20), the method is characterised in that the value documents and objects (2) before being taken over by the security guard (20) are disposed by the sender (10) inside of one or several boxes (3) comprising first security means (9, 9', 9") for disclosing any breaking or attempt of breaking by a person other than the sender (10) or the consignee (30) by self-destruction or self-deterioration of said boxes (3), afterwards said boxes (3) are positioned in the container (4) for transferring it to the consignee by the security guard (20).

The invention relates to an electro-optical device for the photo-polymerization of composite material, and is used in particular in the dental field. The inventive device comprises a light source (2) which is defined by an LED or a group of LEDs. It comprises electrical power supply means consisting of a battery (4) which is associated with a direct current/direct current converter device (7) commonly known as a DC/DC converter, passive means (3) for the evacuation of heat, and a central management unit (5) for operating parameters of the light source for the definition of a determined photo-polymerization energy profile.

The invention concerns a method for making a wall element, in particular a ceiling element, consisting of a polygonal frame (1) whereon is stretched a fabric (3); said method which consists prior to fixing the fabric (3), in bending said frame (1) outwards on each of its sides (5a, 5a', 5b, 5b') so as to provide it with a deflection such that, when the fabric (3) is fixed on the frame (1), the tension exerted by the fabric deforms in reverse said side and brings it back to its initial position before its pre-deformation. Said method is characterised in that the bending is carried out at a distance from the ends of each of the sides.

The invention relates to a device for fixing a crossbar (17) which is intended to connect two control links (9) which are associated with shoe braking means for rail bogies. The inventive device is characterised in that each end of the crossbar (17) is essentially supported by a link (9) and in that it comprises a fixing element (22) which passes through said link (9) and which is housed in one end of the crossbar (17). The aforementioned fixing element (22) is provided with means of ensuring that it remains solidly connected in translation with the link (9).

The invention relates to a device which is used to immobilise a threaded support pin (21) in relation to a fixed element (1, 34), said pin being screwed into a bone part (3, 3a, 3b) along an axis (yy'). The inventive device is characterised in that it comprises a locking sleeve (13) which can be solidly screwed to the fixed element (1, 34, 7) and which is provided with an axial bore (19) in order to receive the pin (21). According to the invention, the axis (zz') of the sleeve screw thread is angularly and/or laterally offset in relation to the axis (yy') of the pin (21) when the latter is in place on the bone part (3, 3a, 3b), and/or the axis of the bore (19) of the locking sleeve (13) is angularly and/or laterally offset in relation to the screw thread axis (6).

The invention relates to a longitudinal flexible heating mat. The inventive mat comprises a thin conductive metal strip (3) which is intended to be supplied with electric current at the ends (C, D) thereof and which is trapped between two flexible, insulating sheets (1, 1'). The mat is characterised in that: (i) the conductive strip comprises at least two elements (3a, 3b) which extend from one of the longitudinal ends (A) of the mat to the other longitudinal end (B) of same, (ii) the first ends (C, D) of the aforementioned elements are intended to be connected to respective electric power terminals, and (iii) the second ends (D, E) of said elements are free and intended to be connected to one another using connection means (7). The invention also relates to a method of producing one such mat.
