    摘要： A pavement marker has an unpotted upper shell and a lower base plate that together define a housing. A number of ribs are disposed in the housing interior oriented substantially perpendicular to the inner wall of the base plate. The upper shell has inclined end faces, an upper face, and is made of a plastic material having moderate to high flexural modulus and a high impact strength. The lower base plate has a planar inner wall and an opposed planar, pavement-engaging outer wall, and is made of a material having a Young's modulus of at least approximately 300,000 PSI (20.7.times.10.sup.8 Pascal). The ribs are formed unitarily with the inner wall of either the upper shell or the base plate, and extend upwardly from the inner wall of the base plate to the inner wall of the shell. A retroreflective lens is positioned on at least one of the first and second opposed side faces of the marker. The pavement marker resists delamination from a roadway surface when secured to the road with a soft adhesive.

    摘要： The invention is a mounting system for a vibrational element. The vibrational element has a longitudinal axis, an outer surface and an axial displacement node. The mounting system includes an isolation member which has an isolation surface, an isolating body, and an engaging portion. The engaging portion is immovably secured to the isolation member and extends radially inward from the isolation body at a point radially opposite the isolation surface. The engaging portion is disposed so as to engage the outer surface of the vibrational element. Radial displacements of the vibration element are substantially decoupled from the isolation surface through the engaging portion.

    摘要： Sound insulation constructions, multilayer constructions for acoustically insulating a source of sound from a receiver that include one or more sound insulation constructions, structures comprising one or more sound insulation constructions and/or multilayer constructions, and a method for acoustically insulating a source of sound from a receiver. In some embodiments, the sound insulation construction includes a first layer and a second layer. The first layer can include a bonded fiber nonwoven web exhibiting a work of compression of at least about 0.7 kJ/m3 and an airflow resistance of no greater than 10,000 Rayls/m. The second layer can exhibit an airflow resistance of greater than 10,000 Rayls/m. In some embodiments, the method includes coupling the first layer to a surface of a vehicle to attenuate sound in at least a portion of the vehicle.

    摘要： An acoustic system for applying vibratory energy including a horn connected to an ultrasonic energy source. The horn defines an overall length and wavelength, and at least a leading section thereof is comprised of a ceramic material. The leading section has a length of at least ⅛ the horn wavelength. In one preferred embodiment, an entirety of the horn is a ceramic material, and is mounted to a separate component, such as a waveguide, via an interference fit. Regardless, by utilizing a ceramic material for at least a significant portion of the horn, the ultrasonic system of the present invention facilitates long-term operation in extreme environments such as high temperature and/or corrosive fluid mediums. The present invention is useful for fabrication of metal matrix composite wires.

    摘要： The horn includes an outer cylinder and an inner shaft connected by a disk. The shaft has an axial input end, and receives vibrational energy at the axial input end and transmits the vibrational energy to the cylinder. The cylinder is hollow and has an inner surface, an outer surface, and first and second opposing end surfaces. The second end surface serves as a welding surface which applies vibrational energy to an object. The welding surface moves with the application of vibrational energy to the input end of the shaft. The disk portion connects the inner shaft to the cylinder and transmits the vibrational energy from the inner shaft to the cylinder.
