Abstract:
A substrate having the following layers in the following order thereon; first dielectric layer, first layer with infrared reflection properties, second dielectric layer, second layer having infrared reflection properties, and third dielectric layer. The thickness of the first layer with infrared reflection properties is 50% to 64% of that of the second layer having infrared reaction properties. The optical thickness of the first dielectric layer is greater than the thickness of the third dielectric layer by at least 100%. The substrate and the layers together exhibit an external reflection color in the range of blue to blue-green at both 0.degree. and 60.degree. incidence angles.
Abstract:
A hydraulic antivibration support comprises first and second rigid strength members, an elastomer body having a thick wall interconnecting the two rigid strength members and defining a hydraulic working chamber, and a thin wall defining a hydraulic compensation chamber which is connected to the working chamber via a narrow channel. The elastomer body is extended by a flexible elastomer tongue which is received in a slot-shaped housing of the second strength member, said housing including a face in communication with the working chamber and a face in communication with the compensation chamber, both faces being closable in alternation by the flexible tongue.
Abstract:
A controllable hydraulic vibration-damping support comprising two strength members interconnected by an elastomer body defining a working hydraulic chamber, an auxiliary hydraulic chamber communicating with the working chamber via a constricted passageway, a pneumatic chamber separated from the auxiliary chamber by a moving wall, an electrically controlled vent device for establishing a connection to the air, which device can be actuated electrically in order to put the pneumatic chamber into communication with the atmosphere, and a check valve allowing air to flow only out from the pneumatic chamber towards the atmosphere.
Abstract:
The invention relates to a transparent substrate, more particularly of glass and having multiple thin layers on which are successively deposited; i) a first dielectric material layer, ii) a first layer having infrared reflection properties, particularly based on metal, iii) a second dielectric material layer, iv) a second layer having infrared reflection properties, particularly based on metal, v) a third dielectric material year, characterized in that the thickness of the first layer having infrared reflection properties corresponding to about 50 to 80%, particularly 55 to 75% and preferably 60 to 70% of that of the second layer having infrared reflection properties.
Abstract:
A hydraulic antivibration support comprising first and second rigid strength members (1, 2) in the form of a plate, and a bell-shaped elastomer body (3, 4) interconnecting the two rigid strength members and forming a working chamber (A) therebetween, and a compensation chamber (B) connected to the working chamber via a narrow channel (C) filled with liquid like the chambers. A hole (13) pierced in the plate is sealed by a flexible decoupling membrane (14) whose periphery is bonded to the rim of the hole by vulcanization.
Abstract:
An active vibratory control device for a vehicle, comprising a link comprising a link body that extends between first and second articulations intended to be connected one to a vibrating member and the other to a chassis, and a mounting base connected to the second articulation of the link so as to enable the link to pivot with respect to the mounting base, this mounting base being secured to a vibration generator.
Abstract:
An anti-vibration device is disclosed comprising an anti-vibration support comprising first and second rigid frames connected together by an elastomeric body and a limiting cap which is snap fitted onto the second frame and designed to be fastened onto a receiving member while clamping the second frame.
Abstract:
A method of manufacturing an antivibration device that comprises a hydraulic element, the method including at least one overmolding step during which a plastics material connection piece is overmolded over the hydraulic element after said hydraulic element has been closed.
Abstract:
An insulated double glazing having the following layers in the following order: first dielectric layer, first layer with infrared reflection properties, second dielectric layer, second layer having infrared reflection properties, and third dielectric layer.

Abstract:
A hydraulic antivibration support comprises first and second rigid strength members, an elastomer body which has a thick wall interconnecting the two rigid strength members and which defines a portion of a working chamber, and a thin wall of elastomer which defines a portion of a compensation chamber that is connected to the working chamber via a narrow channel, the two chambers and the narrow channel being filled with a liquid. The support includes an abutment having no portion that projects into the working chamber from the inside surface of the thick wall of the elastomer body.
