摘要： The invention relates to a process for starting a machine fitted with a rotor on magnetic bearings and a circuit for implementing said process; in order to automate this process, the procedure is such that the fact that an axial stop bears on the rotor at rest and the correct position of the rotor when running -- its unstable equilibrium -- is about half a possible total travel of the rotor away from the momentary rotor stop position is used as information in order to apply electric power to the deflection coil in such a way that the rotor assumes its correct position virtually independently of the offset and that initially one of the two possible rotor stop positions is assumed to be given and an attempt is made to stabilise the rotor at about half of the possible total travel of the rotor from the assumed rotor stop position.

摘要： In a arrangement for producing precise concentrations of gaseous substances and for mixing various gaseous substances in a predetermined ratio, the gaseous substances are fed through a valve (1) having n inlets and m outlets, where n and m are whole numbers. This valve (11) can connect at least one inlet (e.g., 16) with a given outlet for a predetermined time (e.g., t1). The valve is controlled preferably by modulation of pulse width by means of a microprocessor (12). In this way, any desired concentrations of gaseous substances can be readily obtained.
