    摘要: A composite material with acoustic absorption properties of the "sandwich"ype has a core of cellular structure between two skins substantially parallel one of which is cut-out by orifices while the other is devoid of orifices. The core is composed of a plurality of cells each of which extends from one skin to the other. A plurality of small plates, of material with high acoustic resistivity, are inserted into the cellular structure. Each plate has an active part contained in a plane substantially parallel to the skins, so that the active parts form, together, the equivalent of an intermediary wall of high acoustic resistivity dividing the cellular structure into two superposed layers each formed by a mass of sub-cells.

    摘要: Connector receptacles that may be used in a variety of applications, may have a desirable aesthetic appearance, may be durable and reliable, and may be manufactured in a simplified manner. One example may provide a receptacle that may be used in a number of different devices to avoid having to redesign a receptacle for different devices. Another example may maintain a desirable appearance by reducing the chance of marring or functional damage during insertions of an insert.

    摘要: A chair with a curvilinear frame includes two vertically aligned curvilinear tubular side frame members facing each other, a horizontally aligned seat attached to each side frame members by two screws inserted through side member screw hole in each side member and into seat screw holes said seat's right side and left side, and a generally vertically aligned back attached to each side frame members by two screws inserted through side member screw hole in each side member and into back screw holes said back's right side and left side.
