Abstract: A conveying device for use in the field of plastics has a frame and a weighing cell connected to the frame. A separating unit is suspended from the weighing cell. A first coupling is connected to the frame and connects a vacuum source to the separating unit. A second coupling is connected to the frame and connects a conveying line for goods to be conveyed to the separating unit. At least one of the first coupling and the second coupling has a first coupling part connected to the separating unit and a second coupling part connected to the frame, wherein the first and the second coupling parts do not contact each other in a region of no contact. At least one sealing element is provided to seal the region of no contact between the first and the second coupling parts.

Abstract: The present invention relates to a catalyst for the treatment of an exhaust gas of a diesel combustion engine, said catalyst particularly comprising a specific substrate and a coating disposed on the surface of the internal walls of said substrate, the coating particularly comprising a specific first non-zeolitic oxidic material, and a specific zeolitic material comprising Fe and Cu, wherein the catalyst exhibits a weight ratio of Fe, calculated as Fe2O3, relative to Cu, calculated as CuO, Fe2O3:CuO, of less than 0.1:1. Further, the present invention relates to a specific process for preparing said catalyst. Yet further, the present invention relates to a system comprising said catalyst and to a use thereof.

Abstract: A drill string element of a drill string, the drill string element configured to keep the pressure in the annular space between the drill string and the drill hole within calculated limits or to keep the pressures prevailing in the annular space or drill string as small as possible. Settled drill cuttings are brought back into the flow or settlement of the drill cuttings is prevented.

Abstract: The invention relates to a system for laying underground cables or underground lines in the ground near the surface, in a borehole (102) along a laying route (101) between a start point (100) and a target point (110), comprising a boring device (10) comprising an advancing head (12) for creating the borehole (102), a drilling rod (11) and/or a casing (14), wherein the diameter of the advancing head (12) is greater than the diameter of the casing (14) or of the drilling rod (11), so that an annular space (121) is formed between the borehole wall (102) and the casing (14) or the drilling rod (11) and the annular space (121) is provided with lubrication and wherein the advancing head (12) relates to a displacement drilling head (15, 16, 41) or a drilling head system (18) comprising a drilling tool (19) and a drilling tool drive (22) for loosening the ground.

Abstract: A method is provided for securing a Signalling System No. 7 interface, SS7 interface, of a system, via which access to a local mobile radiocommunications network is carried out, in relation to an external system. The method protects the SS7 network access points of telecommunication providers from SS7/MAP attacks by detecting and filtering these attacks.
