Abstract: A vehicle body with a cavity therein. The cavity is optionally closed or opened by a door arrangement with one or more door leaves. The door leaves are connected to a wall of the cavity via multiple-joint hinges. A pivot axis of the door leaves is situated outside the cavity, and the multiple-joint hinges are arranged completely in the cavity without taking up installation space outside the inner volume of the cavity when the door arrangement is in the closed state. This design requires little installation space and allows a great freedom of movement of the door leaves.

Abstract: A system, template, and method of managing virtual control units in an industrial automation facility are provided. The industrial automation facility includes machines. The method includes generating templates including deployment criteria for the virtual control units. Each of the virtual control units is capable of controlling at least one of the machines. The virtual control units are mapped to one or more compute nodes based on the deployment criteria.

Abstract: This disclosure relates to a process for preparing D,L-methionine by feeding carbon dioxide to an aqueous potassium methioninate solution obtained by hydrolysis of 5-(2-methylmercaptoethyl)hydantoin, in order to precipitate out crude methionine, which is separated off and purified. In this process an aqueous solution of the separated-off crude methionine is purified by recrystallization from a solution containing potassium ions and also a crystallization additive. The crystallization additive is a nonionic or anionic surfactant, or a mixture of different nonionic or anionic surfactants. The recrystallization occurs by introducing a 60 to 110° C.-hot methionine solution into a 35 to 80° C.-warm methionine suspension, a temperature of which is lower than that of the introduced solution, such that the temperature of the methionine suspension being maintained between 35 and 80° C. during the addition. The crystallization additive is a sorbitan fatty acid ester or a mixture of different sorbitan fatty acid esters.
