An air guide assembly for a vehicle includes a first duct, a second duct, a rigid first housing, and a vehicle component. The first duct includes a flexible body, an inlet for receiving airflow from an exterior of a vehicle body, and an outlet, where the body of the first duct is compressible from an installed length to a length that is shorter than the installed length, and is expandable from the installed length to a length that is longer than the installed length. The second duct includes a flexible body, a first inlet for receiving airflow from the first duct, and an outlet, where the body of the second duct is compressible from an installed length to a length that is shorter than the installed length, and is expandable from the installed length to a length that is longer than the installed length.

A space-saving broadband resonator configured to install within and utilize inner space of other components and includes a resonator insert having a tubular pipe elongated along a central axis, the tubular pipe having a circumferential outer wall having a plurality of perforation holes spaced apart and extending radially through the circumferential outer wall. An interior of the tubular pipe forms a gas flow duct. A plurality of annular disk-shaped walls provided on and projecting radially outwardly from the tubular pipe. Adjacent annular disk-shaped walls spaced axially part from each other define resonator chambers therebetween. A bell mouth is formed at the second axial end of the tubular pipe, the bell mouth flared radially outwardly.

A sound-absorbing cover comprises a first sound-absorbing layer and a second sound-absorbing layer made of foam, a first skin layer of the first sound-absorbing layer and a second skin layer of the second sound-absorbing layer are layered in a state of being made to face each other, and an air layer is provided between the facing surfaces of the first skin layer and the second skin layer. The rigidity of the first skin layer of the first sound-absorbing layer is different from the rigidity of the second skin layer of the second sound-absorbing layer.

The present invention relates to a slide-topper anti-flapping and noise silencer device. The anti-flapping device features a folding hinge-like component and a pair of spring clamps. The folding hinge-like component has a pivotally connected rectangular upper panel and rectangular lower panel. The folding hinge-like component is secured along a leading edge of a slide-topper with the upper panel adhered to the top surface of the slide-topper and the lower panel adhered to the bottom surface of the slide-topper. Spring clamps are then used to secure the upper panel and the lower panel to the slide-topper. The anti-flapping device secures and stabilizes the leading edge of the slide-topper to eliminate flapping and any other associated noises.

A structural assembly includes a frame and a plurality of panels. The frame includes a wall that at least partially defines an interior region. The plurality of panels is disposed at least partially in the interior region and is coupled to the frame. The plurality of panels includes a first panel and a second panel. The first panel includes a first surface and a second surface opposite the first surface. The first surface defines a first plurality of depressions and the second surface defines a first plurality of protrusions complementary to the first plurality of depressions. The second panel includes a third surface and a fourth surface opposite the third surface. The third surface defines a second plurality of depressions. The fourth surface defines a second plurality of protrusions complementary to the first plurality of depressions. The first panel is coupled to the second panel.

Systems and apparatuses include a hood for a machine including a noise inhibitor housing inhibiting transmission of noise in a horizontal plane from the machine, and a noise diffusive panel supported by the noise inhibitor housing and structured to release noise upward.

A planetary roller extruder section forms a feed part of an extruder. The planetary roller extruder has an internally toothed housing and an externally toothed central spindle disposed centrally within and at a distance from the housing. Planetary spindles are arranged to rotate in a void between the central spindle and the housing. Each planetary spindle has an external toothing meshing with both the housing and the central spindle. At least one planetary spindle has two axially spaced areas with less than a full set of teeth. Those axially spaced areas include a first area having a first number of teeth and a second area having a second number of teeth. The second number of teeth is less than a full set of teeth and more than the first number of teeth.

A passenger suite for an aircraft passenger cabin includes a seat having an adjustable backrest, multiple forward sound drivers, left side drivers, right side drivers, at least one sensor detecting the position of the backrest, and a controller in communication with the drivers and operable to adjust an output of at least one of the drivers based on the position of the backrest. A third driver may be positioned within or behind the seat in communication with the controller. The forward drivers may be tweeter drivers; the side drivers may be midrange drivers; and the third driver may be a woofer driver. In some embodiments, a particular left side driver and a particular aligned right side driver are active to deliver audio content according to the position of the backrest. A surround sound system installable in an aircraft cabin, such as within an aircraft passenger suite.
