Described are polyesters comprising (a) a dicarboxylic acid component comprising terephthalic acid residues; optionally, aromatic dicarboxylic acid residues or aliphatic dicarboxylic acid residues; 2,2,4,4-tetramethyl-1,3-cyclobutanediol residues; and 1,4-cyclohexanedimethanol residues. The polyesters may be manufactured into articles such as fibers, films, bottles or sheets.

Described are film(s) and / or sheet(s) comprising polyesters comprising (a) a dicarboxylic acid component having terephthalic acid residues; optionally, aromatic dicarboxylic acid residues or aliphatic dicarboxylic residues; 2,2,4,4-tetramethyl-1,3-cyclobutanediol residues; and 1,4-cyclohexanedimethanol residues.

A main structure that can be constructed using either solid steel assembly (32) or reinforced concrete assembly (33) acts as the main structural component for new and remodel construction. The main structure whether it uses reinforced concrete assembly (33) or steel assembly is comprised of cells of equilateral size and each cell has a passage between inner and outer wall created using this method of construction. The inner wall uses the passages to secure accompanying structures and systems to a wall that use this structural system. The outer wall uses the passages to secure retaining assembly (34) to the structure. Retaining assembly (34) holds a strata of soil to the wall and creates plateaus along face of outer wall. The plateaus created by securing retaining assembly (34) to main assembly's (32) or (33) give vegetation a place to be planted and secured to a wall that incorporate the construction method of this invention. The passages between the inner and outer walls also nurture the vegetation attached to a structure built using this invention's method of construction by allowing direct access to the roots. By allowing direct access to the roots of the vegetation planted on a structure utilizing the construction method of this invention each plant can receive the optimum amount of irrigation, drainage, and fertilizer.

A crashworthy traffic noise barrier system for use alongside a path of traffic, the crashworthy traffic noise barrier system comprises a crashworthy longitudinal barrier extending substantially parallel to the path of traffic and a crashworthy traffic noise barrier wall supported by the longitudinal barrier. The crashworthy traffic noise barrier wall includes a plurality of upstanding posts attached to the traffic noise barrier wall, at least one panel supported between each adjacent pair of posts in the plurality of upstanding posts, and at least one longitudinal beam spaced above a top surface of the longitudinal barrier and extending across the plurality of upstanding posts for redirecting a portion of an errant vehicle away from the at least one panel. The longitudinal beams redirect energy of the errant vehicle away from the panels such that the panels and any fragments of the panels, remain attached to the traffic noise barrier wall. The panels may be transparent and may be reinforced with plastic bands, plastic threads, or a plastic net.

A sound absorption structure body has a housing has a front side and a side face raised at at least a part of an outer edge section of the front face, a gas adsorption body placed in the internal space, surrounded by the front face and the side face, of the housing and physically adsorbing gas in the internal space, a sealing means for sealing the gas adsorption body from the outside, and an acoustic connection section provided at at least either the front face or the side face and functioning as an acoustic mass for acoustically connecting the internal space of the housing and the space outside the housing. The sound absorption structure body achieves both sound absorption in a low -pitched sound range and downsizing of the sound absorption structure body itself.

A footing for use to support stanchions of sound-barrier walls is a one-piece monolithic element that includes a base having a plurality of prestressing cables therein. A stanchion is accommodated in a bore defined in either a sleeve included with the base or directly in the base. If a sleeve is included, the sleeve includes a plurality of prestressing strands or rebars. One form of sound-barrier wall includes adjacent panels on opposite sides of a stanchion whereby a panel must be lifted in order to tip the stanchion over so wind forces are safely accommodated. Another form of the footing includes projections that extend into the bore. Various forms of sound-barrier wall configurations can be accommodated by the footing.

An inflatable, noise attenuating panel or barrier, comprised of an inflatable air chamber coated with (wrapped in or attached thereto) an acoustic barrier material, with which to construct a variety of structures that benefit from a degree of soundproofing.
