Patent number: 8770169Abstract: Provided is a cover member (7) such as chain cover member for engines, configured to reduce significantly its own vibrations and noises generated or transmitted therefrom compared to other conventional cover members. On its central portion, the cover member (7) of the present invention is provided with circular compartments (17) each defined by a concave surface facing outward and a convex surface facing inward. At least, the concave surfaces facing outward jointly define a continuous curved surface. Therefore, the flat surfaces (flat portions) on the cover member (7) decrease, thereby reducing sound emission, and thus noises from the cover member (7). In addition, when the cover member (7) of the present invention has at least three circular compartments (17), in each three circular compartments (17) adjoining to each other, the three circular compartments (17) are arranged in a triangular pattern, and each one of them circumscribe the other two circular compartments (17).Type: GrantFiled: August 22, 2008Date of Patent: July 8, 2014Assignee: Honda Motor Co., Ltd.Inventor: Yoshiaki Koyama

Publication number: 20140182966Abstract: A panel assembly with a multi-layer patch may be used in any number of different applications in order to reduce noise or vibrations, provide thermal insulation, and/or improve the structural integrity of an underlying part. In an exemplary embodiment where the panel assembly is a vehicle part, the panel assembly includes a main panel, a primary adhesive layer, and a multi-layer patch that includes at least two individual patches and at least one auxiliary adhesive layer. The primary adhesive layer attaches the multi-layer patch to the main panel, and the auxiliary adhesive layer attaches the individual patches together. The size, shape, thickness and/or composition of the different layers of the multi-layer patch may be specifically chosen to exhibit certain sound and/or thermal damping properties.Type: ApplicationFiled: March 22, 2012Publication date: July 3, 2014Applicant: SHILOH INDUSTRIES, INC.Inventors: Jonathan W. Fisk, James F. Keys, Michael C. Adams

Publication number: 20140182967Abstract: An acoustic decorative sheet includes a film layer, a glass cloth layer, and an adhesive layer separating the film layer from the glass cloth layer. The adhesive layer is adhered to the film layer and the glass cloth layer. The film layer and the adhesive layer have a plurality of micro bores disposed there through. The micro bores have a diameter in a range from 20 to 500 micrometers and number from 2 to 700 microbores per cm2. An acoustic assembly includes the acoustic decorative sheet, a substrate; and an air gap at least partially separating the acoustic decorative sheet from the substrate.Type: ApplicationFiled: August 23, 2012Publication date: July 3, 2014Inventors: Yoshihiko Takeda, Jiro Hattori, Toshifumi Sakai

Publication number: 20140151150Abstract: Monolithic acoustically-treated composite structures and methods for fabricating the same are provided. A monolithic acoustically-treated composite structure comprises an internal frame assembly comprising a unitary composite frame structure and at least one acoustic panel assembly. The unitary composite frame structure defines a shape of the monolithic acoustically-treated composite structure to be fabricated. A composite overlay covers the internal frame assembly. The method for fabricating the monolithic acoustically-treated composite structure comprises forming the unitary composite frame structure, including the at least one acoustic panel in the unitary composite frame structure, and covering the internal frame assembly with the composite overlay.Type: ApplicationFiled: February 6, 2014Publication date: June 5, 2014Applicant: HONEYWELL INTERNATIONAL INC.Inventors: Adam Kowal, Jeffrey Hein, David E.

Patent number: 8739924Abstract: An apparatus and method is disclosed for an improved acoustic panel comprising a sound absorbing member defined by a first and second face surface and a plurality of peripheral edges. A sound blocking member is defined by a first and second face surface and a plurality of peripheral edge. The first face surface of the sound blocking member is secured relative to the second face surface of the sound absorbing member for blocking the transmission of sound therethrough. 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
