A rotary transmission device for transmitting control and/or working pressures to a wheel hub. The rotary transmission device has a housing structure in which a piston element is displaceable between a first and a second position relative to the housing structure and relative to a running body of the wheel hub which is mounted so as to rotate relative to the housing structure. To transmit the control and/or working pressures, at least one pressure medium channel is formed in the piston element. In the first position, an air gap is present between an end face of the piston element on the running body side and an end face of the running body on the piston element side, while in the second position, no air gap is present, and the at least one pressure medium channel opens in sealed fashion into at least one pressure medium channel formed in the running body.

Rotary transmission device for transmitting control and/or working pressures to a wheel hub or a vehicle wheel received by the wheel hub

A system () for transmitting control pressures and/or working pressures from a wheel-hub pressure medium supply (), in particular from a wheel-hub pressure medium rotary union (), to a vehicle rim () mounted on the wheel hub (). The system () has a receiving part (), which has a central region () with a central opening () and at least one extension region () projecting radially from the central region (), at least in some regions. The receiving part () can be connected to the wheel hub () by means of the at least one radially projecting extension region (), in a detachable way, and the control pressures and/or working pressures can be transmitted from the wheel-hub pressure medium supply () to the opening ().

A light scanning device for exciting and detecting secondary light, especially fluorescent light, on a sample, comprising a light emission device for emitting exciting light with a wavelength suitable for exciting secondary light on or in said sample, a focussing optics for focussing the exciting light on a subarea of said sample, a sample holding device for releasably holding the sample, a detection unit comprising a detection optics for the secondary light emitted by the sample in response to excitation and a detector device for converting the detected and imaged secondary light into electric signals. In the case of conventional known light scanning devices, scanning is carried out by means of a deflection unit consisting of tilting mirrors. Due to the long path of the light beam, positioning inaccuracies of the tilting mirrors result in major position inaccuracies of the scanning ray bundle on the surface of the sample. For avoiding this disadvantage of the prior art, the light scanning device according to the present invention makes use of a sample holding device which is adapted to be rotated for rotating the sample relative to the exciting light in such a way that different subareas of said sample can be excited by means of the exciting light so as to emit secondary light. Due to the mechanical rotary movement of the sample, a deflection of the scanning light beam relative to the optical axis is not necessary so that precise positioning of the scanning ray bundle on the sample is possible.

Light-scanning device

In a dosing device for analyzing apparatus, particulary for liquid chromatography, with a dosing loop, a change-over valve and a dosing needle (20) which can be introduced into a sample inlet (56) of the change-over valve (24), through which dosing needle (20) sample liquid can be dosed by means of a sample pump (66) into the sample inlet (56) and the dosing loop (22), the dosing needle (20) has a conical sealing surface (138) at its front end. The sample inlet (56) has a sample inlet passage (128) which forms a conical annular shoulder (136). The dosing needle (20) with its conical sealing surface (138) engages this annular shoulder (136) with a defined pre-stress.
