摘要： A method of and apparatus for measuring or measuring-out a predetermined volume of a liquid flowing through a conduit or line, comprising a first conduit section containing a measurement path and at one end connected with the outlet conduit of a connection element which interconnects a first inlet conduit and a second inlet conduit. The first conduit section is operatively connected at its other end through the agency of a first valve with the low pressure side of a pump device. The first inlet conduit is continuously connected with a liquid container via a second conduit section which causes a dynamic pressure drop in the flowing liquid. Additionally, the second inlet conduit is continuously connected with a fluid container and the fluid container is connected via a second valve with a compartment, whereas the liquid container is continuously connected with the compartment and the high pressure side of the pump device opens into said compartment.

摘要： A method of separating signal classes in a stored signal quantum or set of signals correlated to a histogram in that there is looked for the minimum between two neighboring signal classes by mutual comparison of the stored signal values in a partial range of the histogram and there is stored as a separation threshold the characteristic of the thus determined channel characterizing the minimum, so that there can be differently evaluated signal values at different sides of such separation threshold. The invention is preferably used for particle analysis in haematology.
