In another embodiment, the first face surface of the sound blocking member is spaced relative to the second face surface of the sound absorbing member for decoupling the sound blocking member from the sound absorbing member.Type: GrantFiled: March 17, 2009Date of Patent: June 3, 2014Assignee: LJ Avalon LLCInventor: Lahnie Johnson

Patent number: 8708098Abstract: A support membrane designed to be arranged with a covering that can be applied to bearing areas such as floors or even under and on concrete screeds for a floor is provided. Said membrane can also be used in the composition of ceilings and in the composition of residential walls. The membrane includes a base layer made of fibers and designed to be arranged directly on the bearing area so as to absorb sound waves and to level the irregularities of the bearing area, a vapor barrier-anchoring membrane, and optionally an underlay designed to receive the covering and provide an anchor for the finishing products. Said support membrane is characterized in that the vapor barrier-anchoring membrane thereof is applied in liquid form by hot-melting directly on the base layer and on the underlay whenever the latter is used.Type: GrantFiled: December 9, 2009Date of Patent: April 29, 2014Inventor: Sylvain Roy

Patent number: 8635814Abstract: The invention is a wall for interior architecture, particularly for partitioning adjacent rooms, comprising a substantially rigid frame (2) suited to define an external perimeter surface (4) of the wall (1), and one pair of opposite faces (3) constrained to the rigid frame (2) and made of a flexible material. In particular, the opposite faces (3) comprise elastic constraining means (5) suited to maintain them tensioned and substantially parallel to a geometrical plane, while the rigid frame (2) and the opposite tensioned faces (3) delimit an internal hollow region (6).Type: GrantFiled: September 15, 2010Date of Patent: January 28, 2014Assignee: Giplanet SpAInventors: Luca Griggio, Eddy Canton

Patent number: 8579079Abstract: The aim of the invention is to improve acoustic insulation panels of the prior art by proposing a rigid, light panel, the acoustical absorption performance of which is improved thanks to the use of a grid the structure of which enables the same to contribute to the noise absorption function. To this end, the present invention relates to an acoustic insulation panel including two facing panels (2, 4), separated by a solid structure (6) that is substantially planar and has two surfaces (7b, 7c) that are substantially planar and parallel, each of which are rigidly connected to a facing panel, said structure (6) including through-holes (6a) that form a mesh, such that the meshed structure contributes to the noise absorption function.Type: GrantFiled: April 6, 2009Date of Patent: November 12, 2013Assignee: HutchinsonInventors: Thierry Beauvilain, David Maupetit, Sylvie Fageardie, Benoît Palluau

Patent number: 8474573Abstract: The invention relates to a composite sandwich panel (1) comprising at least a web (2) provided between an inner skin (3) and an outer skin (4), each skin being made of a composite material from a plurality of fibrous plies (5, 6, 7, 8), characterized in that a portion of the plies of the inner skin and/or of the outer skin each extends at least partially through the web at an uninterrupted area thereof in order to form together a through-reinforcement (9) extending from the inner skin to the outer skin of the composite sandwich panel. The invention further relates to an aircraft element including such a composite sandwich panel.Type: GrantFiled: August 21, 2009Date of Patent: July 2, 2013Assignee: Societe Lorraine de Construction AeronautiqueInventors: Jean-Luc Pacary, Paulo Francisco
