Publication number: 20230028139Abstract: The invention relates to a process for devulcanizing a vulcanized rubber mixture, comprising the following steps: A) providing or producing a vulcanized rubber mixture, B) comminuting the vulcanized rubber mixture to a granular material composed of vulcanized rubber particles, where the vulcanized rubber particles have a maximum particle diameter of 100 mm, C) extruding the vulcanized rubber particles produced in step B) in a twin-screw extruder at a shear rate of less than 100 s?1, where the temperature of the vulcanized rubber particles during extrusion is less than 200° C., to give a devulcanized rubber mixture having a temperature above 100° C., D) cooling the devulcanized rubber mixture in a further kneading unit, so as to give a devulcanized rubber mixture having a temperature in the range from 50° C. to 100° C. The invention further relates to an apparatus for performing the process and to the use of the apparatus for devulcanization of a vulcanized rubber mixture.Type: ApplicationFiled: October 27, 2020Publication date: January 26, 2023Applicant: Continental Reifen Deutschland GmbHInventors: Inga Soetbeer, Konstantin Efimov, Nils Krüger, Shreyas Naik, Thomas Völker, Hilke Wolf

Patent number: 9802446Abstract: Self-sealing tire sealants are provided which contain fragments and/or residues of expanded solids, where the solids are selected from the group containing expandable graphite and microspheres. In some aspects, the microspheres include at least isobutane and/or isopentane as blowing agents. The microspheres may also have a shell containing at least one polymer, and in some cases the polymer is at least one copolymer of acrylonitrile and methyl acrylate. The self-sealing tire sealant may further include graphene structures. In some aspects the interior of a pneumatic vehicle tire has the self-sealing tire sealant disposed on the inner surface, opposite the tire tread, and the layer thickness of the tire sealant may be from 0.5 to 8 mm.Type: GrantFiled: February 8, 2017Date of Patent: October 31, 2017Assignee: Continental Reifen Deutschland GmbHInventors: Markus Dahlke, Dieter Jeromin, Joe Guardalabene, Thomas Völker, Fei Liu, Andreas Tyburski, Martin Convey

Patent number: 9683088Abstract: A process for regenerating sulfur-crosslinked rubber vulcanizates to regenerates, wherein at least one regenerating agent is used in the regeneration. The regenerating agent is selected from the group consisting of dithiophosphoryl polysulfides and/or silanes having a polysulfane group. Regenerates which have been produced by means of the process lead to improved or equal rolling resistance indicators and a lower compression set in vulcanized rubber mixtures compared to regenerates known in the prior art.Type: GrantFiled: March 2, 2015Date of Patent: June 20, 2017Assignee: Continental Reifen Deutschland GmbHInventors: Carla Recker, Lena Mueller, Thomas Voelker

Patent number: 8300906Abstract: A method is described for displaying an image of an illumination field of a medical operation. The method includes recording an image at an illumination field of an operation, receiving a color temperature signal representative of an operating lamp that illuminates the illumination field of the operation, based on the received color temperature signal, adjusting parameters to compensate for differences in the received color temperature signal from white balance to produce a white balanced image, and outputting the white balanced image to a monitor.Type: GrantFiled: November 15, 2007Date of Patent: October 30, 2012Assignee: Trumpf Medizin Systeme GmbH + Co. KGInventor: Thomas Voelker
