Patent number: 7568553Abstract: A noise barrier system composed of a base and a transparent superstructure. A support holds at least two adjacent transparent noise barrier elements and includes a point-fastening of the transparent noise barrier element. A position of upper holding points of the transparent superstructure is arranged at a height of from 70 to 90% of a total height of the transparent noise barrier element and at a distance of from 3 to 50 times a thickness of the transparent noise barrier element from a vertical edge. An upper side of the transparent noise barrier element has a flexure, an angle of the flexure being from 30° to 90° from vertical, and a width of an angled region being from 5 cm to 50 cm, and an entire length of a lower side of the sheet is secured within a groove-shaped depression.Type: GrantFiled: October 9, 2003Date of Patent: August 4, 2009Assignee: Roehm GmbH & Co.

Publication number: 20070003756Abstract: The invention relates to a method for production of a plastic body, made from a plastic obtained by means of a radical polymerisation with single- or multi-sided, inorganic coating containing silicon. The coating of a substrate is firstly achieved with a paint composition, containing inorganic particles in a solvent which can optionally contain additional flow improvers. One or more of such coated substrates can be used for the construction of a polymerisation chamber, in which the coated sides lie within the chamber. After radical polymerisation of a monomer mixture in the presence of a polymerisation initiator, the internal inorganic coating of the substrate transfers into or onto the surfaces of the radically polymerised plastic or of the plastic body. The invention further relates to the corresponding plastic body and the uses thereof.Type: ApplicationFiled: July 2, 2004Publication date: January 4, 2007Applicant: Roehm GMBH & Co.

Patent number: 6305492Abstract: The invention relates to a noise-protection wall-segment, for example for roads, motorways or railways and such like, said noise-protection wall-segment including transparent sheets, preferably a transparent plastic sheets, and means fixing the sheets. The transparent sheet is shaped around a perpendicular to the installation surface of the assembled noise-protection wall, the term ‘shaping’ being understood to mean vaulting and/or folding. Moreover, in the case of plastic sheets, preferably made of acrylic glass, threads of synthetic material can be embedded in the sheet which counteract splintering in the event of fracture and constitute a recognized bird impact protection device.Type: GrantFiled: February 17, 2000Date of Patent: October 23, 2001Assignee: Rohm Gesellschaft mit beschrankter HaftungInventors: Bernd Oleiko, Norbert Brand, Klaus Oberlander

Patent number: 6231799Abstract: Substantially sulfur free thermoplastic PMMA containing molding compositions are utilized with non-ferrous metal tools for the manufacture of molded articles. The use of such molding materials having a sulfur content of less than 50 ppm reduces the wear on the non-ferrous metal tools, particularly when utilized with injection molding and pressure molding. As a result of the use of sulfur free molding masses where it necessary to utilize tools of non-ferrous metal, there is a substantial economic advantage in the use thereof.Type: GrantFiled: February 17, 1999Date of Patent: May 15, 2001Assignee: Roehm GmbHInventors: Peter Kempf, Norbert Brand, Helmut Schwind, Stefan Roth, Holger Moritz
