  • Publication number: 20220186647
    Abstract: A heating device for an exhaust system has an electrically conductive foamed part and at least one stabilization part for the foamed part. The foamed part includes two end faces, an outer circumference and at least one recess starting from the outer circumference and extending in the axial direction from one to the other end face. The recesses produce sections which are opposite each other at a distance and continue into each other, forming a current path as a resistance heating element. The stabilization part at least partially fills the recess and mechanically couples the sections to each other, but does not electrically couple them to each other.

  • Patent number: 11174776
    Abstract: A purification component comprises at least one block for purifying exhaust gases, and a casing that defines a circulation channel for the exhaust gases extending along a longitudinal axis, and in which the purification block is housed. The casing comprises an inlet portion, an outlet portion, and a central portion arranged between the inlet portion and the outlet portion, and with the central portion surrounding the purification block. A thermal insulator covers the whole of the casing. The thermal insulator comprise a first part, having a first temperature resistance, arranged radially facing the purification block, and a second part, having a second temperature resistance greater than the first temperature resistance, covering at least the inlet portion of the casing.

  • Patent number: 6997720
    Abstract: This interconnection module for the base of an electronic device casing carries out the transfer, at the faces of the printed circuit boards (4, 5) supporting the components of the device housed in the casing, of a field of connection points with the external environment of the casing embodied by the rear ends of the pins of a semi-connector fixed to the back of the casing while still retaining the compactness of the casing despite a very large number of connection points with the external environment of the casing (several hundreds of them). This module takes the form of a three-panel structure with a central panel 7 fixed to the rear ends of the pins of the semi-connector (3) mounted on the back of the casing and two side panels (8, 9) folded and placed flat against each other, joined to the longitudinal edges of the central panel (7) by flexible printed circuit elements (10, 11) and supporting the field of connection points transferred to the level of the faces of the boards (4,5) of the electronic device.

  • Patent number: 5423080
    Abstract: Microwave circuits, namely the circuits relating to the transmission-reception part and to the filtering of the microwave transceiver, are mounted on one and the same multilayer printed circuit and their electromagnetic insulation comprises, firstly, elements of the printed circuit such as conductive tracks on one of the faces of the printed circuit, metallized holes drilled in the tracks and close to one another so as to fulfil the role of an electromagnetic barrier and, at least in the case of some of them, a conductive plate and, secondly, attached elements with, especially, a thick metal lattice surmounted by a lid, the lattice resting on the conductive tracks.
