Abstract: The invention relates to an unbalance type exciter (6) for a soil compaction device. This exciter comprises a carrying structure (5) as well as an unbalance weight (8, 9), which by means of a bearing (11a, 11b) is supported at the carrying structure (5) in rotatable manner around a rotation axis (Y) which in the intended use is stationary with respect to the carrying structure (5), for generating an intermittent exciting force for causing the carrying structure (5) in the intended use to vibrate. The bearing (11a, 11b) of the unbalance weight (8, 9) is arranged at least partially within the space which is circled by the unbalance weight (8, 9) when rotating around the rotation axis (y). Owing to the fact that this space is used for receiving at least part of the bearing of the unbalance weight (8, 9) it becomes possible to provide unbalance type exciters (6) having very small axial overall length.

Abstract: The invention relates to a hinge assembly for connecting two vehicle parts to a vehicle that is capable of crab steering, has articulated frame steering and comprises articulating vehicle axles. Four structural elements are connected to each other by four hinge connections, the hinge centers being arranged in a common plane in a basic state, such that they form a frame which is substantially rigid with respect to thrust forces in that plane. Two of the structural elements forming opposite sides of the frame can in each case be rotated about a rotational axis located in said plane with respect to the other three structural elements. Furthermore, the hinge connections are designed in such a manner that, starting from the basic state, the two rotational axes can be articulated relative to each other in that one of the rotational axis can be pivoted out of the plane.

Abstract: The invention relates to a sample holder having an insulation body (10; 50) and a first electrode (3; 33) and a second electrode (4; 34), wherein the first electrode (3; 33) and the second electrode (4; 34) project into the sample container (2; 32), the first electrode (3; 33) and the second electrode (4; 34) are connected to each other via the insulation body (10; 50), the sample container (2; 32) is filled with a dielectric liquid (5; 35), and the first electrode (3; 33) is assigned to a gas collection chamber (6; 36). The invention further relates to an assembly for the electrodynamic fragmentation of samples (38), having such a sample container (2; 32), a process container (22; 41), and means (24, 27; 39, 39.1, 39.

Abstract: The invention relates to a hinge assembly (1) for connecting two vehicle parts (2, 3) to a vehicle that is capable of crab steering, has articulated frame steering and comprises articulating vehicle axles. It comprises four structural elements (4, 5, 6, 7) which are connected to each other by four hinge connections (8, 9, 10, 11), the hinge centers of which are arranged in a common plane in a basic state, in such a manner that they form a frame which is substantially rigid with respect to thrust forces in that plane. Two of the structural elements (4, 6) forming opposite sides of the frame which is substantially rigid with respect to thrust forces can in each case be rotated about a rotational axis (D1, D2) located in said plane with respect to the respective other three structural elements.

Abstract: The invention relates to an arrangement with a high voltage electrode (1) and a process vessel (2) assigned to the high voltage electrode (1), wherein the high voltage electrode (1) and the process vessel (2) can be positioned relative to each other in such a manner that the high voltage electrode (1) with its operational electrode end (5) in an operating position is immersed in the process vessel (2) and in a non-operating position is located outside the process vessel (2). Furthermore, the arrangement includes a grounding device (3), which is designed in such a manner that upon a positioning in the non-operating position it automatically is brought into contact with the operational electrode end (5) for grounding the high voltage electrode (1).
