Abstract: An electrical bushing having an anti-rotation mounting flange for preventing rotation of a body element of the electrical bushing is provided. The electrical bushing includes a mounting flange, at least one locking element and a body element having a circumferential protrusion. At least one first recess is formed in the circumferential protrusion, and the at least one locking element is configured to engage with the at least one first recess and with the mounting flange for restricting relative rotation of the body element relative to the mounting flange about a longitudinal axis R. A further aspect provides an electrical transformer including at least one electrical bushing according to the above. A yet further aspect provides a method for mounting the electrical bushing according to the above.

Abstract: To provide a method for producing a catalyst flow element (100) by means of which robustly constructed catalyst flow elements (100) usable in a broad field of operation are producible, it is proposed that the following method steps be performed in the method: providing a main body (102) including a plurality of flow channels (104); introducing slots (116) into partition walls (110) of the main body (102), which separate the flow channels (104) from one another such that at least two adjacent flow channels (104) are connected together fluidically within the main body (102) in a common end region (130) of the at least two adjacent flow channels (104); and arranging channel closures (118) in the common end region (130) for fluid-tight closure of the common end region (130) while maintaining the fluidic connection between the at least two adjacent flow channels (104) in the common end region (130).

Abstract: Disclosed is a process for navigating an unmanned vehicle over a predeterable course, respectively such a vehicle. A steering and control unit determines by a first sensor at least the stretch covered and detects by at least one second sensor objects in the vicinage the position of which is stored in the steering and control unit and which serve the purpose of checking the position of the vehicle computed on the basis of the covered stretch. In accordance with the present invention the distance of the vehicle from the objects in the vicinage stored with their exact position in relation to the planned path in the steering and control unit is ascertained by the second sensor at points on the path spaced at intervals. The ascertained distance is compared with the stored distance of the planned coordinates of the point on the path from the object in vicinage.
