Publication number: 20240308445Abstract: A system includes multiple drive modules, each for at least one actuator of a wheel or an axle of a vehicle. Each drive module has a bus interface for connecting to a bus, a switching signal input and a switching signal output. The drive module is configured to operate in an operating mode and a learning mode. The drive module has a switch and is configured to use the switch in the operating mode to conductively connect the switching signal input to the switching signal output and, after a transition from the operating mode to the learning mode, to interrupt the connection between the switching signal input and the switching signal output. The drive modules are connected in series via the switching signal inputs and switching signal outputs.Type: ApplicationFiled: May 28, 2024Publication date: September 19, 2024Inventors: Robert Sohn, Ralph Schumacher, Carsten Lehr, Johann Lucas

Patent number: 12033766Abstract: A method for conditioning of spent ion exchange resins from nuclear facilities comprises the steps of: mixing the spent ion exchange resins with water to form a reaction mixture; setting and controlling the pH of the reaction mixture in a range from 1.0 to 3.5, preferably in a range from 2.0 to 3.0; adding an oxidant to the reaction mixture, with the temperature of the reaction mixture maintained at 90°° C. or less so that the spent ion exchange resin and the oxidant react with each other to form an aqueous reaction solution comprising the organic reaction products of the spent ion exchange resin; and electrochemically oxidizing the organic reaction products, wherein carbon dioxide is produced and a carbon-depleted aqueous reaction solution having a TOC (total organic carbon) value of less than 50 ppm is obtained. Furthermore, an apparatus for the conditioning of spent ion exchange resins from nuclear facilities is described.Type: GrantFiled: November 28, 2019Date of Patent: July 9, 2024Assignee: FRAMATOME GMBHInventors: Gert Seybert, Robert Lehr, Bertram Zeiler, Philip Schuberth, Steffen Weiss

Publication number: 20240139769Abstract: A method of texturing a wall or ceiling with non-acoustical joint compound by providing a collapsible bag having an opening at its top and is adapted to contain non-acoustical joint compound for forming a textured coating on the wall or ceiling and providing a spray nozzle having a low pressure input port, a joint compound suction port attached to the opening at the top of the collapsible bag, and an output port for spraying the non-acoustical joint compound. A low pressure stream of air from an air gun attached to the low pressure input port urges a small quantity of the non-acoustical joint compound to be sprayed out of the spray nozzle when the bottom of the collapsible disposable bag is raised above its top to either allow or force the joint compound to flow into the suction port and into the interior of the spray nozzle.Type: ApplicationFiled: January 4, 2024Publication date: May 2, 2024Inventor: Steven Robert Lehr
