Abstract: The invention relates to a device for detecting a break-in attempt on an opening (2) moveably mounted relative to a frame (3), characterised in that it comprises a sensor (4) connected to a supply and processing circuit, said sensor (4) including two electrically conductive layers between which an insulating layer is provided, each of the conductive layers being connected to an electric power supply, wherein said sensor (4) is to be inserted between the frame (3) and the opening (2).

Abstract: A heating device for the transformation of a material, includes: a lower mold element or matrix, made of an electrically conductive material and having a molding zone for contacting with the material to be transformed; an upper element that lacks a molding zone, made of an electrically conductive material; inductor elements for generating a magnetic field that envelops the matrix and the upper element, with the matrix and the element being electrically insulated from one another during the induction heating phase so that the surfaces opposite these two elements delimit an air gap in which the magnetic field that induces currents circulates at the surface of the molding zone of the matrix, thus making it possible to localize the action of the inductors at the interface of the molding zone/material to be transformed; and deformable pressure element, arranged between the matrix and the upper element, able to exert uniform pressure on the material to be transformed.

Abstract: The invention concerns a device for heating a surface by induction, in particular for molding or transforming a part made of thermoplastic or thermosetting composite material. The device comprises a body having at least one portion made of magnetic and heating conducting material wherein is provided a plurality of closed cavities proximate the surface to be heated, each cavity surrounding a field winding. The heat produced by induction on the walls of the cavity is transferred by conduction to the heating surface. The distance between the cavities and the position of said cavities relative to the heating surface are such that the heating is substantially uniform on said surface.

Abstract: The invention relates to a method and a device which are used to heat materials in order to produce objects industrially, especially by mass production, and which allow a large variety of transformation methods.

Abstract: A device for transforming thermoplastic matrix composite materials or thermosetting materials, includes two mold casings that are mobile relative to each other, electrically conductive, and include a molding zone designed to be in contact with the material to be transformed. The faces of one of the two mold casings are situated so as to be facing magnetic field generator, except for the molding zones, and are coated with a shielding layer made of a non-magnetic material preventing the magnetic field from penetrating into the mold casings. The mold casings are electrically insulated from each other during the molding phase so that the faces of the two mold casings demarcate an air gap wherein flows the magnetic field that induces currents at the surface of the molding zones thus localizing the heating at the interface between the molding zone and the material to be transformed.

Abstract: Mold for transforming a material comprising a plastic and/or a composite material, wherein the mold includes a mold body having at least one impression arrangement. A heating arrangement directly heats at least one of the material and an intermediary surface impression arranged adjacent to the material. The at least one impression arrangement includes an insulating material that prevents transfer of calorific energy from the material to the mold body, and vice-versa. The insulating material includes a mineral resin which includes an association of non-organic constituents. An insulating device is arranged one of within the insulating material and between the insulating material and the mold body. This Abstract is not intended to define the invention disclosed in the specification, nor intended to limit the scope of the invention in any way.
