Abstract: A ball valve (1) has a blocking element (3) movably guided in a fluid passage of a valve housing (2) and movable by an actuating device (4) from a pass-through position connecting at least two connecting points (5) to one another in the valve housing (2) into a blocking position interrupting this connection, and vice versa. A sealing device has at least one sealing ring which, together with its central opening, comprises the fluid passage (6) and seals the fluid passage along at least one sealing gap. The ring profile of the sealing ring has a ring opening that interrupts this profile such that the sealing ring changes from an initial shape to an installation and different shape that seals the sealing gap with a predefinable pretension having an increased sealing force effect.

Abstract: A method is for determining a gas amount, which can be dispensed by a dispensing device, in particular in the form of a hydrogen gas amount, by a gas meter (36). A part of the main gas stream flowing to the dispensing device (26) is branched off by a flow divider (20) mounted upstream of the dispensing device (26), when viewed in the direction of the gas stream, for a quantitative measurement in the secondary flow by the gas meter (36).

Abstract: An apparatus for routing cables in wind turbines has a plurality of bushings (17) for cables distributed on at least one base body (3, 5) that has a preferably round contour. The bushings (17) are provided with a guiding arrangement (27; 38; 39, 41; 43; 48) permitting the cables to move relative to the part of the bushing (17) that surrounds the guiding arrangement.

Abstract: A valve device, in particular, in the form of a ball valve (1), having a blocking element (3) movably guided in a valve housing (2), which may be brought via a fluid passage (6) by means of an actuating device (4) from a pass-through position connecting at least two connecting points (5) to one another in the valve housing (2) into a blocking position, which interrupts this connection, and vice versa, and having a sealing device having at least one sealing ring which, together with its central opening, comprises the fluid passage (6) and which seals it along at least one sealing gap, is characterized in that the ring profile of at least one sealing ring of the sealing device has a ring opening that interrupts this profile in such a way that the sealing ring changes from an initial shape to an installation shape differing therefrom, in which it seals the sealing gap that can be assigned thereto with a predefinable pretension having an increased sealing force effect.

Abstract: An apparatus for routing cables in wind turbines, in which a plurality of bushings (17) for at least one cable are distributed on at least one base body (3, 5) that has a preferably round contour, characterised in that the bushings (17); are provided with a guiding arrangement (27; 38; 39; 41; 43; 48) which permits the respective cable to move relative to the part of the bushing (17) that surrounds the guiding arrangement.

Abstract: A clamp for securing components, in particular string-like or linear structural members, like pipelines, hoses, or cables, has at least one clamp part (3). The clamp part outer contour (4) delimits at least partially a receiving space (5) for receiving the component. The one clamp part (3) has a mechanism (6) for minimizing corrosion, in particular, crevice corrosion, at every component that is held. The mechanism has at least one sacrificial element (7) that is visibly consumed with the onset of corrosion and continued duration of use of the clamp fastener. The respective sacrificial element (7) is placed, as an independent component, on the outer contour (4) of the clamp part (3).

Abstract: A ball valve has a valve housing (2) receiving ball spindle (6) pivoted around an axis in the housing (2). A ball body (12) as a blocking element is between the input part and the output part of a media passage (4) of the housing. The flow opening (14) located in the ball body (12) is alignable with the passage (4) for unblocking the ball valve by turning the ball spindle (12). The ball body (12) is supported on two identical end sections (8, 10) connected to and axially spaced from the ball body (12). The support on at least one end section (8, 10) is a support cover (26) having integrated slide bearing elements (34, 36) detachably mounted on the housing (2).

Abstract: 2. A clamp for securing components, in particular string-like or linear structural members, like pipelines, hoses, or cables, having at least one clamp part (3), of which the outer contour (4) delimits at least partially a receiving space (5) for receiving the respective component, at least one clamp part (3) having a mechanism (6) for minimizing corrosion, in particular, crevice corrosion, at every component that is held, is characterized in that the mechanism has at least one sacrificial element (7) that is visibly consumed with the onset of corrosion and continued duration of use of the clamp fastener and that the respective sacrificial element (7) is placed, as an independent component, on the outer contour (4) of the assignable clamp part (3).

Abstract: A ball valve, in particular for highly pressurized media, with a valve housing (1) in which a ball spindle (16) which is pivoted around an axis in the housing (1) at an axial distance from the pivot support has a ball body (12) as a blocking element between the input part and the output part of a passage (4) of the housing (1) for media, and the flow opening (14) located in the ball body (12) can be oriented to the passage (4) for media for unblocking the ball valve by turning the ball spindle (12), characterized in that the ball spindle (12) is supported on two end sections (8, 10) which are made identical and which are connected to the ball body (12) on both sides and that the support on at least one end section (8, 10) is formed by a support cover (26) which has integrated slide bearing elements (34, 36) and which can be detachably mounted on the housing (1).
