Publication number: 20080272508Abstract: The invention relates to a method and a device for producing spherical particles from a melted mass of plastic. According to the invention, said melted mass is transformed into droplets by means of a droplet-forming nozzle (10); after falling a certain distance, the droplets are crystallised at least on the surface thereof; the droplets are then supplied to a crystallisation stage in which they are fully crystallised; and are then supplied to an postcondensation stage wherein solid phase polycondensation takes place. In order to ensure surface crystallisation without the risk of adhesion both among the drops and to parts of the device, the drops fall in a crystallisation stage (45) having a cloth element or a sheet metal element comprising openings or a fluidised bed chamber through which gas flows in order to swirl the drops.Type: ApplicationFiled: October 22, 2007Publication date: November 6, 2008Applicant: BUEHLER AGInventors: Brent Allen CULBERT, Andreas Christel, Erhard Krumpholz, Theodor Juergens, Rudolf Geier

Patent number: 5635590Abstract: The invention relates to a process for the treatment of contaminated ethylene glycol resulting during a polycondensation process for the production of polyester. In the course of this polycondensation process contaminated ethylene glycol is continuously predistilled, subjected as a distillation residue to secondary distillation, condensed and then returned to the polycondensation process as decontaminated ethylene glycol, so that an in-line recovery is achieved, which makes superfluous an external distillation installation for the treatment of contaminated ethylene glycol.Type: GrantFiled: August 10, 1995Date of Patent: June 3, 1997Assignee: John Brown Deutsche Engineering GmbHInventors: Jurgen Rink, Klaus Stemmer, Rudolf Geier

Patent number: 4569811Abstract: A staple-fiber band is made by first spinning synthetic-resin filaments with spinnerets and drawing the filaments as roving at a predetermined feed speed from the spinnerets. The roving is then cooled without greatly stretching it so it has relatively high residual stretch and is then stored. Without intermediate treatment the roving is heated to a predetermined temperature and then stretched it to a relatively small residual stretch. The stretched roving is then thermofixed and then stretch-torn. Finally it is textured. During the heating, thermofixing, stretch-tearing, and texturing steps the roving is held under tension so that its filaments cannot tangle. When the filaments are of polyester they are stretched at between 60.degree. C. and 120.degree. C. and thermofixed at a temperature that can be somewhat higher.Type: GrantFiled: September 28, 1982Date of Patent: February 11, 1986Assignee: Didier Engineering GmbHInventor: Rudolf Geier
