The intermediate piece has a connection portion which is plug-connected and adhesively bonded to an end of the fiber-plastic composite profiled part. The end of the fiber-plastic composite profiled part is plugged onto the connection portion of the intermediate piece and is adhesively bonded on the inner surface to the connection portion.

Abstract: A method and device are provided for directly screwing together at least two components using a self-drilling and tapping screw which has a head and a shank formed onto the head with a self-tapping thread section and a hole-drilling section for flow drilling.

The shank has a self-tapping thread section and, in front thereof, a punch-forming section for flow punch forming. The shank further has at least one cutting edge with a chip removal function, which is essentially located in front of the self-tapping thread section, wherein on the one hand this cutting edge makes it possible to generate a clearance hole into at least one of the components by turning the screw, while on the other hand not impairing a flow punch forming in another component. A component assembly may be joined together by use of at least one such self-drilling and tapping screw.

Abstract: A method for determining a criterion of the severity of an accident by means of an acceleration signal and a solid-borne sound signal. The signal edge direction of the absolute value of the acceleration signal is detected. If the signal edge of the absolute value of the acceleration signal drops, the solid-borne sound signal which occurs in the process is evaluated. The solid-borne sound signal may be integrated and the criterion of the severity of the accident is derived therefrom. This criterion of the severity of the accident can be used directly, or as a function of criteria, to trigger the protection devices.

Abstract: For the milking of animals, in particular cows, in a milking installation comprising a plurality of milking places, a method and a device are proposed wherein the milk yields extracted during a milking session at some milking places or the characteristics corresponding to the milk yields are determined and evaluated and in particular compared with prognoses as to milk yield or characteristics. These measures allow on the one hand that sufficiently accurate data are provided for herd management while on the other hand the investment cost for a milking installation are reduced.

Abstract: A silencer operative for a compressor or a vacuum pump, in particular for a compressor or a vacuum pump that operate according to the displacement principle, which in either case compresses a current of gas, in particular an air current, such that the silencer includes an entrance for the gas current that leaves the compressor, as well as an exit, the silencer including a branching region having an inflow channel which branches into two channel sections, such that a first channel section is constructed as a main conduit to conduct the gas current further, and a second channel section forms a branch that is closed at its end. The branch has an axial preferential direction oriented parallel to the direction of flow of the gas current in the inflow channel, so that the gas current impinges frontally on the branch that is closed at its end.

The die member has a plurality of polymer channels and a plurality of extrusion orifices connected to a respective one of the channels to form a extrusion orifice section. A heating medium system has additional heating medium conduits between channels and a supply and intermediate header for heating the channels (radially from each side) and providing once in and once out heating medium flow. The die member may be formed by high temperature brazing of components using coordinated solder (Ni based or gold-nickel) and component heat treatment temperature. A thin hard face coating may be provided on raised extrusion orifice ring faces around each extrusion orifice section.

The damping device has a throttle point configured so as to allow the compensation space to be pressurized by a relatively low pressure.

Abstract: Damping valve assembly includes a first damping valve, which, in a first operating range, opens as the flow velocity of the damping medium increases, where a second operating range with a progressive damping force characteristic is influenced by a throttle in conjunction with a control slide, which can be moved into a closed position. The control slide has a pressure-actuated surface, which, as a function of the flow velocity of the damping medium, acts in the closing direction on the control slide.

Abstract: Vibration damper with amplitude-dependent damping force includes a cylinder, in which a piston rod, carrying a piston, is guided with freedom of axial movement, where the piston divides the cylinder into a working space on the piston rod side and a working space on the side away from the piston rod. The piston rod carries at least part of a housing, which is mounted in the direction of the piston rod-side working space, and where a separating body is supported inside the housing with freedom to slide. The separating body divides the housing into first and second working chambers, where the first working chamber is connected by at least one radial connecting opening to the piston rod-side working space and the second working chamber is connected by a connecting channel to the working space on the side away from the piston rod. At least a part of the housing is connected to the piston rod by a weld.

Abstract: A piston is guided with freedom of axial movement in a damping medium-filled pressure tube, the piston dividing the pressure tube into a working space on the piston rod side of the piston and a working space on the side away from the piston rod.

The outgoing flow side of the valve is connected at least to the working space on the piston rod side of the piston and a compensating space. The adjustable damping valve can be controlled by way of a sidestream inside the fluid connection between the working space on the side away from the piston rod and the working space on the piston rod side of the piston, the adjustable damping valve having a sidestream channel leading to the compensating space.
