Abstract: An automated laboratory system, which includes a vessel supply rack for supplying vessels in a vessel supply position, a movable vessel pick-up table for picking up and moving a vessel from the vessel supply position to the vessel filling position, a movable metering table disposed above the vessel pick-up table and configured for picking up and moving at least two metering containers configured to hold chemical substances, the metering containers being able to be positioned above the vessel filling position to fill chemical substances into a vessel, a scale, disposed underneath the vessel filling position for determining a substance quantity filled into a vessel, and a stirrer, disposed above the vessel filling position, for mixing of substances filled into a vessel. Also described is a method for operating such a laboratory system.

Abstract: A gas sensor, in particular a lambda probe, for ascertaining the pollutant and/or oxygen content in emission gases of internal combustion engines, having a housing accommodating at least one sensor element, the sensor element having a section on the terminal side and a section on the measuring-gas side, and having a connecting element that connects the sensor element, which has a plurality of electrically conductive contact areas, at its terminal-side section to a plurality of electrically conductive supply leads. The gas sensor has the feature of a connecting element which is formed from a spring element produced in one piece from ceramic material.

Abstract: A line connector connecting a first electric line which has a first contact connection portion and a second electric line which has a second contact connection portion. The line connector includes an enclosing tube which surrounds the first electric line and which has an end portion. The end portion is embedded in a plastic extrusion coat. The first and second contact connection portions are also provided in the plastic extrusion coat. The line connector also includes a sealing device which is situated on the end portion of the enclosing tube. Furthermore, the line connector includes a clamping device which is encased by the plastic extrusion coat and which radially presses a seal element of the sealing device on the enclosing tube.

Abstract: A resetting circuit for microprocessors which facilitates the operation of a microprocessor even with extensively disrupted supply voltages. For this purpose, in a voltage stabilization circuit for supplying a microprocessor there is monitored the voltage difference between the supply voltage and the operating voltage through a potential difference-controlled flip-flop. This flip-flop generates a resetting signal when the supply voltage has approached its minimum permissible value, in effect, is therebelow. Upon the subsequent rise of the supply voltage, the resetting signal is maintained until there is again reached a predeterminable percentage of the rated value of the supply voltage.
