Noise Damper Bonded to Tire Using Adhesives
The invention relates to a tire comprising a circumferential tread having an outer tread surface and an inner innerliner surface; at least two spaced-apart beads; sidewall portions extending between the tread and the beads; and a belt-like foam noise damper having first and second terminal ends, wherein the noise damper lines the innerliner surface; wherein the noise damper is secured to the innerliner surface via an adhesive situated between the noise damper and the innerliner, wherein the terminal ends of the noise damper are cut at an angle of less than 90 degrees, overlap each other, and the overlapped second terminal end of the foam is joined to the first terminal end by the adhesive present underneath the second terminal end, and wherein the adhesive has weight in the range of 30 to 800 grams per square meter of foam surface.
PELLETIZATION OF RECYCLED CEILNIG MATERIAL
Described herein is an acoustical building panel that comprises a body formed from a first component comprising a fibrous material, and a binder; and a second component comprising pellets of a recycled material, wherein the second component is present in an amount ranging from about 25 wt. % to about 45 wt. % based on the total weight of the body.
METHOD AND DEVICE FOR PRODUCING A PROFILED ELEMENT
A profile element is useful for sealing building-structure joints, especially for sealing against sound and smoke and optionally against fire. An apparatus is useful for manufacturing such profile element and to the use of the profile element manufactured according to the invention for the acoustic, smokeproof and/or fireproof sealing of connecting joints in drywalls, especially of expansion joints.
Applying cymatics resonant frequencies for particle distribution and means of capturing for processing
Methods for creating nodal vibration patterns in a granular material on a metal sheet, capturing the patterns in a working material and using the working material with the captured shapes to provide an end product. A tone is applied to the metal sheet which, based on the properties of the sheet and the tone frequency, create a specific pattern of nodal lines of vibration in the sheet. A particulate material placed on the sheet takes the shape of the nodal lines. An adhesive-coated sheet of working material is applied to the metal sheet and captures the particles in the shape of the nodal lines. The sheet of working material with the captured nodal line patterns is then used to produce a structure with strength, stiffness and other properties based on the embedded wave patterns. Alternately, the particles can be directly fused into a skeleton in the nodal line pattern shape.

What is described is a method for manufacturing a profile element for sealing building-structure joints, especially for sealing against sound and smoke and optionally against fire, to an apparatus for manufacturing such a profile element and to the use of the profile element manufactured according to the invention for the acoustic, smokeproof and/or fireproof sealing of connecting joints in drywalls, especially of expansion joints. In particular, an improved method is described for continuous and endless manufacture of such a profile element.
Method of manufacturing a membrane for an electro-acoustic transducer
A method of manufacturing a membrane for an electro-acoustic transducer through spray coating of a liquid elastomer solution is provided. The method includes spraying the liquid elastomer solution, which may comprise a silicone, onto a mold having the desired membrane geometry, allowing the solution to cure and remove the membrane from the mold. The mold can be configured to hold other components of an electro-acoustic transducer that will be attached to the membrane after the curing step. Also provided is a membrane for an electro-acoustic transducer comprised of an elastomer and made using spray coating of a liquid elastomer solution.
AIRY BEAM-ENABLED BINARY ACOUSTIC METASURFACES FOR UNDERWATER ULTRASOUND BEAM MANIPULATION
A method of fabricating a binary metasurface for producing an ultrasound Airy beam for underwater ultrasound applications is provided. The method includes generating an amplitude distribution of an Airy beam at a frequency, and converting the amplitude distribution into a binary phase profile. The method also includes generating a 3D printing design of a binary metasurface based on the binary phase profile, wherein the binary metasurface includes ridges and grooves defined by neighboring ridges, a ridge having a thickness corresponding to a phase delay of /2 of the Airy beam between water and a 3D-printable material. The method further includes additively manufacturing the binary metasurface with the 3D-printable material based on the 3D printing design.
Sound absorbing body
A sound absorbing body comprises a non-woven fabric or a non-woven fabric laminate, the non-woven fabric or the non-woven fabric laminate comprises a fiber that has an average fiber diameter of less than 3,000 nm, the non-woven fabric or the non-woven fabric laminate has a thickness of less than 10 mm, the non-woven fabric or the non-woven fabric laminate has a unit thickness flow resistance of greater than 4.0 E+06 Ns/m.sup.4 and less than 5.0 E+08 Ns/m.sup.4, and the non-woven fabric or the non-woven fabric laminate has a bulk density of greater than 70 kg/m.sup.3 and less than 750 kg/m.sup.3.
ARTICLE COMPRISING PLATED COMPONENT
An article at least comprising two components contacting with each other, in which at least part of a surface of at least one of the two components being plated, is provided, which is excellent in plating adhesion and impact resistance and thus is hard to be damaged on the plated surface and excellent in appearance even when one of the two components is brought into contact with the plated part of the other component, and is preferably suppressed in occurrence of unpleasant sounds such as squeaking noise. At least one of the two components of the article is formed of a thermoplastic resin composition (X) comprising a rubber-reinforced aromatic vinyl resin (A) in at least part of the portion that contacts the plated portion of the other component.
METHOD OF FABRICATING A MINIATURE DEVICE HAVING AN ACOUSTIC DIAPHRAGM
A method of forming a device having a compliant member includes providing an elastomeric layer in an uncured state. The elastomeric layer is pre-cured to increase its viscosity. Subsequently, a bobbin and housing, each having an end, can be positioned such that their ends extend at least partially into the elastomeric layer. The elastomeric layer is cured to secure it to the bobbin housing. Examples of pre-cure and cure operations include one or more of a thermal cure, evaporative cure and ultraviolet cure, and the application of moisture, microwave energy and chemical additive. Due to the increased viscosity after the pre-cure, the migration of elastomeric material is substantially reduced relative to an uncured elastomeric material. The reduction in elastomeric material migration results in smaller menisci formed along the walls of the housing and bobbin, and reduced thinning of the compliant member formed at their ends.
