Abstract: This frame (3), which is intended to be attached to the periphery of a panel (2), comprises a main portion (4), a surrounding wall (41) of which is designed to surround the edge (21) of the panel, and attachment means for attaching the frame relative to the panel, which comprise at least one locking element (6). This locking element (6) is connected to the main portion (4) by means of a hinge (9) and is movable relative to the main portion between an open position, in which the panel (2) is capable of being inserted into the surrounding wall (41) without interaction with the locking element, and a closed position, in which, when the surrounding wall (41) surrounds the edge (21) of the panel, the locking element is facing a main face (22) of the panel.

Abstract: The present invention relates to a method of overmolding at least one portion of seal (J) onto a peripheral part of a glazed element (V), said seal comprising at least one insert (1), this insert having an overmolded portion comprising a baseplate (2) and a projecting portion (4) oriented along an axis (A) for prepositioning, positioning or fixing the glazed element (V) in an aperture that it is to close, said method being characterized in that, during injection, the insert is positioned in the molding cavity using at least one pin (11) collaborating with a positioning means (5) situated on said overmolded part so that said baseplate (2) comprises, on a face facing toward the glazed element, at least one bearing tab (6) extending toward the glazed element and coming into contact therewith and, on an opposite face, a mount (3) having a free face supporting said projecting part (4) and which is not covered with the plastic of which the seal is made and in that during release from the mold, the mold is opened an

Abstract: A method of manufacturing an assembly including a strip inserted between two substrates, the strip being formed from at least one damping material, includes providing the two substrates; providing the strip; evaluating equivalent real stiffness per unit length K?eq of the strip and of the equivalent loss factor tan ?eq; and manufacturing the assembly by inserting a strip having an equivalent real stiffness per unit length of at least equal to 25 MPa and the equivalent loss factor of at least 0.25 between the two substrates.

Abstract: An acoustic insulating glazing unit including at least two substrate sheets, joined together around their periphery using a device that forms a sealed joint and a spacer frame, which device, with the two substrate sheets, defines a flat cavity filled with a gas. At least one microcavity is formed over at least part of the periphery of the cavity, constituting a zone of thermoviscous losses from the cavity along at least one of internal walls of the two substrate sheets by which the cavity is bounded. Dimensions of the at least one microcavity are chosen to promote propagation of some of the acoustic waves from the cavity into the microcavity, generating thermoviscous losses and thus reducing acoustic energy of the cavity. A mechanism is provided to contain the acoustic waves escaping from the microcavity.

Abstract: A strip to be inserted between two elements to cause acoustic attenuation of noise propagating through at least one of the two elements. The strip is made of at least one plastic-based damping material, the strip having an equivalent real stiffness per unit length K?eq equal to at least 25 MPa and an equivalent loss factor tan ?eq equal to at least 0.25.

Abstract: Strip (3) to be inserted between two elements (1, 2) in order to cause acoustic attenuation of the noise propagating through at least one of the elements, the strip (3) being made of at least one plastic-based damping material i, characterized in that the strip (3) has an equivalent real stiffness per unit length K?eq equal to at least 25 MPa and an equivalent loss factor tan ?eq equal to at least 0.25.

Abstract: The invention relates to an acoustic insulating glazing unit. This glazing unit comprises two glass sheets (12, 14) joined together around their periphery by means of an assembly (16) forming a seal (163) and an insert frame (161) which defines, with the two glass sheets, a flat cavity filled with a gas, and a waveguide fastened between the glass sheets, internal to the insert frame. The waveguide consists of at least one straight tubular section (20, 22, 24, 26) placed on the periphery of the gas-filled cavity along one side of the glazing unit, this section being provided with a transverse partition (28) which closes the latter in its length direction, the said partition being placed at a length position along the section which depends on the acoustic mode of the cavity that it is desired to disorganize, this partition defining, on either side of it, two chambers (30, 31) which communicate with the cavity through the ends of the sections.

Abstract: A glass pane including at least a glass sheet provided with heating strips powered by collectors, the heating strips being divided in groups. The power supply of the different groups is provided sequentially, each group being powered once per sequence. The supply is provided by a device equipped to measure the outside temperature and the temperature of the outer surface of the glass, to determine a minimum heating time for each group according to the outside temperature, and to maintain the heating in the group as long as the outer surface temperature of the glass opposite the group is not higher than the melting point of ice.
