Patent number: 8576687Abstract: The invention relates to tonearm tracking mechanisms in phonograph players and mechanical devices constructed for the purpose of reproducing or playing back recorded audio material previously impressed, in the form or grooves, onto a surface of a disk, which are commonly called phonograph players or turntables. Such disk is commonly called, among other similar words, a phonograph record or a vinyl disk. The present invention is a tangential tracking tonearm mechanism, wherein the tonearm bearing subassembly has two rotary bearings in the lateral plane and a coupling linkage built into a compact subassembly. The collective contribution of these elements, when properly configured and appropriately adjusted, make, during playback of audio material on a disk, reduced playback distortion over radial tracking mechanisms and closely mimics the conditions under which nearly all masters are made.Type: GrantFiled: October 5, 2012Date of Patent: November 5, 2013Inventor: Frank Schröder

Patent number: 7176309Abstract: The invention relates to a method for producing melem-free melamine by means of aqueous processing of a melted mass of melamine which is obtained using a high-pressure method. According to the inventive method, the melted mass of melamine is quenched by means of an aqueous solution containing alkalis, following the isolation of the off-gases, and is directly transferred into an aqueous alkaline melamine solution, out of which the melamine is then crystallized. The invention thus enables melamine to be obtained, with a melam content of less than 1000 ppm and a melem content of less than 50 ppm. The invention also relates to a quenching agent.Type: GrantFiled: November 14, 2002Date of Patent: February 13, 2007Assignee: AMI - Agrolinz Melamine International GmbHInventors: Frank Schröder, Wolfgang Ruech, Christoph Neumüller, Ferdinand Koglgruber, Hans Christian Wagner
