Abstract: A method serves for starting a polyphase electric motor which is operated in a star connection. The method conductively bridges at least one winding part of a phase of the motor and electrically disconnects the bridged winding part, in order in this manner, to supply a higher voltage to the remaining, electrically effective windings, and thus to increase the flow of current and thus the torque.

Abstract: A method is provided for degassing a transport chamber (1) of a metering pump. The method is based on performing impulse generation, wherein gas bubbles arising from the gas-forming fluid and adhering to the inner surfaces in the transport chamber (1) are released from the surfaces, wherein the gas bubbles (4.4′, 8.8′) present in the transport chamber (1) accumulate, perform a motion (c) in the direction of the pressure valve (6), and form an accumulated gas bubble (7) on the transport chamber side of the pressure valve (6). An increase in pressure causes the accumulated gas bubble present at the pressure valve (6) to escape from the transport chamber (1) as discharged gas bubbles (7′) into the pressure line. A metering pump having a device present in the transport chamber for performing the impulse generation is also provided.

Abstract: The device for energy-optimization on operation of several centrifugal pumps controlled in rotational speed, in a hydraulic installation, begins firstly with determining which pumps as pilot pumps are assigned directly to a consumer and which pumps are hydraulically connected in series upstream of the pilot pumps. Thereafter, one or more energy-optimization circuits are formed, which in each case consist of one or more pilot pumps and of one or more pumps connected in series upstream, which deliver into the pilot pumps, wherein the energy-optimization circuits are selected such that the pumps connected in series upstream in each case are assigned to only one energy-optimization circuit, whereupon the energy-optimization circuits are energy-optimized with respect to the pumps.

Abstract: A method produces electronic components in particular electronic sensors for pressure and differential pressure measurement. Firstly, the semiconductor structure of the electronic components is produced on a wafer. An insulating oxide layer is then applied. A protective metal layer is subsequently applied. The metal layer is applied in sections only in those regions of the wafer in which no splitting, for example by mechanical separation, occurs later. The electronic components thus formed in the wafer are then divided up into individual elements.
