Abstract: A suction handpiece for a dental treatment unit has a negative pressure connection which can be connected with a negative pressure source of the treatment unit. A saliva connection of the suction unit can be connected with a saliva suction cannula and an atomized spray connection that can be connected with an atomized spray suction cannula. A branched flow path connects the negative pressure connection with both the saliva connection and the atomized spray connection and includes a branching section on which a negative pressure channel ending on the negative pressure connection divides into a saliva channel ending on the saliva connection and an atomized spray channel ending on the atomized spray connection. The atomized spray channel at its narrowest point has a first cross sectional area which is at least twice as large as a second cross sectional area at the narrowest point of the saliva channel.

Abstract: A float valve, in particular for draining condensate in a medical compressed-air system, including: a float; a valve seat, which defines a valve opening having a valve opening cross-sectional area qA; and a closure element for opening and closing the valve opening cross-sectional area qA of the valve opening. The closure element can be controlled by means of the float between a completely open position X and a completely closed position Y. The closure element is elastic and is part of a partial opening mechanism, which is designed to successively open the valve opening cross-sectional area qA of the valve opening between the completely closed position Y and the completely open position X as a result of the elasticity of the closure element.

Abstract: An x-ray phosphor plate system has an x-ray phosphor plate, which is configured to be exposed by x-ray light in a recording region, and which carries a shadowing marker, which is arranged in the recording region, on at least one side of the x-ray phosphor plate. The system also has a phosphor plate reader, which is configured to read the exposed x-ray phosphor plate in order to produce an x-ray recording. The shadowing marker has a shadowing effect in respect of x-ray light that is so small that the shadowing marker is only weakly identifiable, and/or only identifiable by way of image artefacts, and/or not identifiable when the x-ray recording is observed by a user. The phosphor plate reader instead has an identification algorithm, which is configured to identify whether or not the x-ray light was shadowed by the shadowing marker during the exposure.

Abstract: A device for reading out an exposed imaging plate, having a light source producing a read-out light, a deflecting unit sequentially directing the read-out light at the imaging plate with a read-out spot in order to read out the imaging plate, whereby a traveling read-out spot can be produced there, a detector unit for fluorescent light, which is emitted by the imaging plate during the reading out by means of the read-out light, and a control device for controlling the light source, the deflecting unit, and the detector unit. The control device performs a preliminary read-out of the imaging plate in order to determine read-out parameters and to subsequently read out the imaging plates using the determined read-out parameters.

Abstract: A device and method for reading an exposed imaging plate generate read-out light and utilize a deflection unit to direct the read-out light in a scanning movement over the imaging plate. The deflection unit has a micromirror to deflect impinging read-out light towards the imaging plate. The micromirror can swivel about a first swivel axis and about a second swivel axis distinct from the first. A detector unit detects fluorescent light emitted from the imaging plate at locations where the read-out light impinges. An evaluating unit evaluates signals received from the detector unit and builds up an image that is stored in the imaging plate. The evaluating unit takes into account, when evaluating the signals received from the detector unit, that points on the imaging plate are subjected to the read-out light variably often and/or for variable time lengths while the micromirror oscillates about the first and the second swivel axis.
