Patent number: 10434452Abstract: An air purification plant, having a partition wall for the spatial separation of a dirty-air space, which is disposed upstream, from a clean-air space, which is disposed downstream, which partition wall has a support frame and a plurality of filter boxes which project from the support frame in the direction of the dirty-air space, and the filter boxes have at least one filter wall which extends from the support frame into the dirty-air space. The filter boxes are in each case open only in the clean-air space which is disposed downstream, wherein filter walls, which face one another, of adjacent filter boxes in each case form a filter pocket which is open on the upstream side and at the bottom, and for switching from one filter pocket into an adjacent filter pocket a suction nozzle is moved through below the filter box which separates the two filter pockets.Type: GrantFiled: December 11, 2014Date of Patent: October 8, 2019Assignee: LUWA AIR ENGINEERING AGInventors: André Remschak, Jürgen Wehner

Patent number: 9572464Abstract: The present invention relates to a vacuum cleaner, comprising a carrier part, a liquid container, and a suction head. A bracket is pivotably fastened to the liquid container, so that the bracket can be used as a positioning element for the suction head. The suction head can be fixed in a parking position that is tilted by an angle (?) greater than 0° from the top edge of the container, in that the suction head lies on the bracket. The bracket is latched to the container in the parking position.Type: GrantFiled: February 26, 2013Date of Patent: February 21, 2017Assignee: PRO-AQUA International GmbHInventor: Jürgen Wehner

Patent number: 9169072Abstract: A conveying device with a revolving, extensively extended conveying member having an upper run section and a lower run section, wherein the conveying member is deflected in two head-end regions that lie opposite one another. The conveying device includes a drive device arranged in a head-end region and having an electric drive motor and a drive shaft coupled thereto. The drive motor includes a motor shaft that leads away from the motor at both sides and that is connected to drive shafts arranged on both sides. The motor shaft and the drive shafts are arranged coaxially, and the drive device is arranged within the conveying device between side limitation devices, the upper run section, and the lower run section and, in the conveying direction is arranged between the two head-ends of the conveying member.Type: GrantFiled: July 19, 2012Date of Patent: October 27, 2015Assignee: WRH WALTER REIST HOLDING AGInventor: Jurgen Wehner

Patent number: 9108802Abstract: A conveying device with a revolving, extensively extended conveying member with an upper run section and with a lower run section, wherein the conveying member is deflected in two head-end regions that lie opposite one another. The conveying device includes a drive device arranged in a head-end region and having an electric drive motor and a drive shaft coupled thereto. The drive shaft has at least one drive member for driving the conveying member at least partly wrapping the drive member. The drive motor includes a motor shaft that is connected to drive shafts arranged on both sides of the motor, wherein the motor shaft and the drive shafts are arranged coaxially. The drive device is arranged within the conveying device between side limitation devices and between the upper and lower run sections and, in the conveying direction, is arranged between the two head-ends of the conveying member.Type: GrantFiled: July 19, 2012Date of Patent: August 18, 2015Assignee: WRH WALTER REIST HOLDING AGInventor: Jurgen Wehner

Patent number: 7576458Abstract: A coolable housing shell for an electric machine, which is produced as a cast part, accommodates a concentric interior rotor/stator arrangement, coils, and end windings, and comprises a clear, open, through passage that is embodied in a symmetric, concentric, and/or coaxial manner relative to an imaginary axis of rotation of the machine. Said housing shell is interspersed with one or several cooling channels so as to form a coolant circuit. The inner surfaces of the shell and the inner walls of the channel/s have a coating via a cathodic dipping varnish method.Type: GrantFiled: October 20, 2003Date of Patent: August 18, 2009Assignee: Baumuller Nurnberg GmbHInventors: Hans-Jürgen Wehner, Günter Sonnauer
