Abstract: A safety sealing device includes a support. An electronic safety circuit is glued to one face of the support. The electronic safety circuit includes a winding of fine wire connected to an electronic component. The electronic component is activated and interrogated by outside checking means via the winding, which acts as an antenna. The electronic component may be coded so that it responds to the interrogation with its code. The safety sealing device may further comprise differentiated gluing means. When attempting to tamper with the support to which the safety circuit has been glued in order to unseal a receiving article, the attempt at ungluing or a tearing causes a break in the continuity of the electronic circuit. As a result, the electronic component no longer responds to an interrogation with its code, thus assuredly indicating that the safety sealing device has been tampered with.

Abstract: A method is described by which it is possible to obtain modules comprising a body of synthetic material, including an electronic circuit, having two main faces absolutely smooth and without swellings at the place where the circuit is enclosed in the body. The body includes two sheets having either an impregnating resin or a certain quantity of gas or air, the electronic circuit being disposed between the two sheets and these being pressed together at a predetermined temperature. A module is thus obtained having at least one electronic circuit which can include a coil serving as an antenna, the module being able to be cut in credit card format and being able to serve as an identification badge. The same method and the same substances can be used to make a module having an electronic circuit with a housing, contact tracks being flush on one of the main faces of the module. Composite modules having the two types of circuits can also be made using the same method.

Abstract: The fixing process according to the invention of a winding to one or more electronic circuits permits elimination of an important manufacturing step of the processes according to the prior art, whether the positioning, then the gluing or the precise fixing of the winding or of the core to be wound on the electronic circuit or circuits. By a suitable arrangement of the electronic circuit or circuits and of the possible core, independently of one another, on a holding tool according to the invention, a semi-finished product is obtained, also according to the invention, made up of the circuit or circuits and the winding, the mechanical connection between them being ensured solely by the copper wires producing, moreover, the electrical connecting between the two elements. The finished component according to the invention will be obtained by disposing the preceding semi-finished product on a support ensuring a permanent mechanical connection between the two elements.

Abstract: A marking device includes an electronic part, made up of an electronic circuit and an antenna, in the form of a winding, which is fixed to a support part, which is a portion of a strip of a flexible material, and which is covered with at least one layer of a thermoplastic, thermoadhesive or self-adhering material. By applying the device to a garment and, by employing a separate electronic mechanism to enter electronic data into a memory of the electronic circuit, it is possible to identify the garment, thus marked, with the aid of a code-reading apparatus of the separate electronic mechanism.

Abstract: The process for assembly of a coil with or without a core on a printed circuit comprises placing the printed circuit in the winding machine before starting the winding. When the Flyer brings the wire for the winding, it causes the latter to pass over a metallized path of the printed circuit while keeping said wire taut. After the Flyer has effected the number of turns necessary for the winding, it will carry the wire along, passing onto a second metallized path, always keeping it taut. The soldering of the two end wires of the winding on the respective metallized paths will take place very easily since each of said wires is held taut at the location where the soldering is to take place. This process permits automating the production of miniaturized electronic circuits comprising a winding.

Abstract: The head (11) of a winding form (1), including two metal paths (12a, 12b), is held between two jaws (30, 31) of the chuck (3). A winding mechanism (40) leads one end of a winding wire (23) above one of the metal paths, being guided by a first guide pin (39a) and a front face (30b) of one of the jaws. After having executed a winding (2) about the core (10) of the winding form, the winding mechanism leads the other end of the winding wire (24) away, passing above the other metal path and being guided by another guide pin (39b; 39c). The chuck used in this way makes it possible to wind fine wire about the core of a very small winding form and to weld the ends of the winding wire to the metal paths without having to go and pick up these ends.

Abstract: A shield which is substantially opaque to electro-magnetic radiation is formed by connecting together webs or strips of a sheet of metallized flexible shielding material, the pieces being placed together in overlapping or abutting relation and secured by a fluid-permeable shielding material. The shielding portions are joined together by an electrically conductive glue.
