Publication number: 20190224034Abstract: The invention relates to a head support, which is formed as a one-piece symmetrical shaped geometrical body having substantially an X-shape with a central middle part, from which legs stretch outwardly each diagonally opposite to each other. The head support also includes a neck strap that holds the head support in place between the chin and upper chest area of the person wearing the head support. The head support is easy to handle and its X-shape offers several advantages. This includes the adaptation of the same to the body of the person on two different support heights.Type: ApplicationFiled: June 22, 2017Publication date: July 25, 2019Inventor: Matthias Mersmann

Patent number: 9643191Abstract: A vertical mill for grinding material to be ground and a method for this are claimed, wherein the vertical mill has a grinding table and one or more grinding rollers. A ring duct with blade ring for a transport gas flow ascending around the grinding table is provided. An annular gap distance is present between a downwardly projecting oversize material cone and the upper region of the grinding rollers, through which annular gap distance a proportion of fine particles is also fed back in a recirculating manner to the grinding table. In order to overcome this disadvantage, a barrier gas flow flowing from inside to outwards is provided in the region of the gap distance, whereby the recirculation of grinding particles of a certain size can be prevented.Type: GrantFiled: March 26, 2013Date of Patent: May 9, 2017Assignee: LOESCHE GMBHInventor: Matthias Mersmann

Patent number: 7798809Abstract: A method of controlling the operation of a bulk good grate cooler for cooling hot cement clinker, for example, in a process-controlled manner is provided in order to ensure that the volume flows of cooling air in all areas of the cooling grate and/or the residence time in the respective area of the bed of the goods to be cooled can be matched to the cooling requirements occurring in each area. A control intervention is carried out during the operation of the grate cooler with respect to the respective local cooling air volume flow and/or with respect to the respective local speed of conveyance of cooling grid according to the respective bulk good bed height measured per area and/or the bulk good bed temperature and/or the cooling air through-flow resistance such that if a modification occurs in one or several of the measured parameters, i.e., bed height, bed temperature and through-flow resistance, the respective local cooling air volume flow and/or the conveyance speed of the grate system is altered.Type: GrantFiled: November 3, 2005Date of Patent: September 21, 2010Assignee: KHD Humboldt Wedag GmbHInventors: Matthias Mersmann, Karl Schinke, Thomas Binninger

Patent number: 7484957Abstract: The invention aims at providing a bulk material cooler particularly for hot cement clinker, wherein the conveyance performance and the efficiency of the cooler are enhanced and problems due to wear are reduced. According to the invention, the cooling grates of several adjacent, elongated bottom elements extending in longitudinal direction of the cooler are put together, said bottom elements being movably controlled independently of one another between a work clearance stroke position in the direction of conveyance of the material to be cooled and a return stroke position in such a way that the material to be cooled is gradually conveyed through the cooler according to the walking floor transport system, wherein the bottom elements are configured as hollow bodies and enable the cold air to go through yet prevent grate sifting of the material to be cooled.Type: GrantFiled: November 25, 2004Date of Patent: February 3, 2009Assignee: KHD Humboldt Wedag GmbHInventors: Matthias Mersmann, Karl Schinke
