摘要： The apparatus for detecting gases comprises a photoacoustic gas detector 35, in which the intensity-modulated absorbed test light beam 32' is converted into noise and detected by means of microphone 36. The photoacoustic gas detector 35 is acoustically decoupled from the gas collecting point 54 by a gas-permeable diaphragm 52 or a rigid, porous material 52'. The gas chamber 35' of photoacoustic detector 35 can be scavenged by means of supply lines 38, 38' and valves 56, 56'. It is advantageous to use a thermal source 32 intensity-modulated by phase lag. The signal is processed at microphone 36 by means of a N-path filter comprising cyclic switch 63 and R-elements 62, 65, 65'. The apparatus can be used for detecting CO.sub.2 and CO.

摘要： An apparatus for cleaning airless sprayers having an upwardly open container for receiving fresh water, as well as an inlet connectable to a water supply, and is characterized in that the container has a level control by means of which the level of the fresh water in the container can be maintained at a predetermined value, and in that the inlet opens into at least one nozzle, by means of which fresh water can be discharged in a directed manner into the interior of the container.
