Patent number: 10213941Abstract: A granulating device having a cutting knife head for cutting strands of melt into granules in a granulator housing. A perforated plate with die openings, from which strands of melt is extruded into the granulator housing, projects into the granulator housing. The cutting knife head, which has at least one cutting knife arranged radially on its outer circumference, is driven by a rotating drive shaft. The granulator housing has a first coolant inlet and an outlet for a mixture of coolant and granules. In addition, the granulator housing has a second coolant inlet that is independent of the first coolant inlet and that supplies a coolant flow for direct granule cooling to at least one co-rotating cooling nozzle bore in the cutting knife head through a coolant chamber and a stationary coolant pipe oriented coaxially to the drive shaft.Type: GrantFiled: May 2, 2016Date of Patent: February 26, 2019Inventor: Joachim Sommer

Patent number: 8939651Abstract: A bearing assembly includes at least first, second and third raceway elements that are each separable from each other and at least first, second and third rows of truncated-cone-shaped rolling elements. The first and second raceway elements are disposed side-by-side in an axial direction of the bearing assembly and oppoe the third raceway element in a radial direction of the bearing assembly. The first and second rows of rolling elements are disposed between the first raceway element and the third raceway element and the third row of rolling elements is disposed between the second raceway element and the third raceway element. The rolling elements of the first and second rows commonly roll on a first raceway of the third raceway element and the rolling elements of the third row roll on a second raceway of the third raceway element, which is not parallel to the first raceway.Type: GrantFiled: March 21, 2011Date of Patent: January 27, 2015Assignee: Aktiebolaget SKFInventors: Joachim Sommer, Armin Olschewski, Rainer Spies, Arno Stubenrauch

Patent number: 8226396Abstract: The invention relates to a device for the production of granulate grains from a plastic melt, having a nozzle plate with at least one nozzle opening from which a strand of the plastic melt is discharged into a processing chamber, and a cutting tool having at least one cutting blade that may be moved against the nozzle plate by means of a feed device, wherein the plastic strand discharged from the nozzle opening of the nozzle plate can be fragmented into granulate grains by the cutting blade moving relative to the nozzle opening. The nozzle plate has a diamond coating at least on the surface thereof facing the cutting tool, with the hardness of the diamond coating being greater than the hardness of the cutting blade, and with the average roughness of the diamond coating being greater than the average roughness of the cutting blade by at least a factor of two.Type: GrantFiled: March 5, 2008Date of Patent: July 24, 2012Assignee: Automatik Plastics Machinery GmbHInventors: Hans J. Scholl, Joachim Sommer

Patent number: 4147897Abstract: A busy signal connecting set is immediately released by the disengagement of a connecting station participating in an existing connection, and a state of interception is established for the subscriber circuit of the subscriber station which has not yet released. The subscriber circuit is connected with a house set for the purpose of connecting the busy signal by way of time switching equipment which is activated after a delay time in response to production of the state of interception.Type: GrantFiled: July 21, 1977Date of Patent: April 3, 1979Assignee: Siemens AktiengesellschaftInventors: Norbert Springer, Walter Oberhauser, Joachim Sommer
