Patent number: 11359639Abstract: A waste water pump includes an impeller (12) and a surrounding pump housing (4), wherein an impeller side chamber (20) is formed between the impeller (12) and the pump housing (4). The impeller side chamber (20) has a first seal (16) between the impeller (12) and the pump housing (4), towards the intake side (32) of the impeller (12), and a second seal (18) between the impeller (12) and the pump housing (4), towards the pressure side (14) of the impeller (12). The first seal (16) is provided with a conveying device (28, 30) configured to convey debris from the impeller side chamber (20) to the intake side (32) of the impeller (12). The second seal (18) is provided with conveying device (38, 40) configured to convey debris from the side chamber (20) to the pressure side (14) of the impeller (12).Type: GrantFiled: October 12, 2017Date of Patent: June 14, 2022Assignee: GRUNDFOS HOLDING A/SInventor: Poul Johannes Henning

Patent number: 10190057Abstract: A method (10) of synthesizing Fischer-Tropsch products (20) includes feeding a synthesis gas (30) to a moving-bed Fischer-Tropsch synthesis reactor (16) containing a Fischer-Tropsch catalyst in a moving catalyst bed and catalytically converting at least a portion of the synthesis gas (30) in the moving catalyst bed to Fischer-Tropsch products (20). The Fischer-Tropsch products (20) are removed from the moving-bed Fischer-Tropsch synthesis reactor (16). The method (10) further includes, while the moving-bed Fisher-Tropsch synthesis reactor (16) is on-line, withdrawing a portion (50) of the Fischer-Tropsch catalyst from the moving-bed Fischer-Tropsch synthesis reactor (16), adding a reactivated Fischer-Tropsch catalyst (57, 58) to the moving-bed Fischer-Tropsch synthesis reactor (16), and adding a fresh Fischer-Tropsch catalyst (60,58), in addition to the reactivated catalyst (57,58), to the moving-bed Fischer-Tropsch synthesis reactor (16).Type: GrantFiled: October 26, 2015Date of Patent: January 29, 2019Assignee: SASOL TECHNOLOGY PROPRIETARY LIMITEDInventors: Richard Neil Walsh, Jean Louis Gauché, Hendrik Wilhelmus Joubert, Albertus Maritz Van Wyk, Johannes Henning Viljoen, Marcel Juergen Krause

Patent number: 9500204Abstract: A waste water pump includes an impeller (10) having a suction port (12) with a sealing surface (14) which annularly surrounds this and which bears on a stationary seal (18). At least one groove (28) is formed in the sealing surface (14) and to both sides extends beyond a bearing-contact region of the stationary seal (18) on the sealing surface (14). The stationary seal (18) having a first end (30) in connection with an impeller side chamber (20) and an opposite second end (32) is in connection with the suction side of the impeller (10). The pump also includes means (34) for producing turbulences arranged in the impeller side chamber (20) adjacent the seal (18).Type: GrantFiled: May 3, 2013Date of Patent: November 22, 2016Assignee: Grundfos Holding a/sInventors: Benny Fredslund Hansen, Poul Johannes Henning

Patent number: 9234523Abstract: A submersible pump includes an impeller (8) arranged in a pump housing (2). A seal (22) seals the impeller (8) with respect to a stationary part of the pump housing (2). The seal (22) includes a sealing ring (24) arranged on the impeller side. The sealing ring engages in a second sealing ring (26) arranged on the pump housing side. The sealing ring (26) on the pump housing side has at least one hole (28) for discharging solid particles from the impeller (8).Type: GrantFiled: November 23, 2010Date of Patent: January 12, 2016Assignee: Grundfos Management a/sInventor: Poul Johannes Henning

Patent number: 7510520Abstract: A device senses the presence of the distal end of a source wire in a reference position within a guidance channel of an afterloading apparatus for positioning an energy emitting source at a desired position within an animal body for radiation therapy treatment. The source wire is driven from the reference position through a guidance channel and a catheter tube. A sensing device detects the presence of the distal end of the wire. The sensing device has a pivotal lever element mounted near the guidance channel. The lever element is in a first position, when the distal end of the source wire is not present in its reference position and the lever element is in a second position, when the distal end is present in its reference position. The presence of the distal end and the energy emitting source can be sensed at several important operational positions.Type: GrantFiled: February 3, 2004Date of Patent: March 31, 2009Assignee: Nucletron B.V.Inventors: Arie Luite Visscher, Johann Henning
