    摘要: Disclosed are a device and a method for continuously monitoring and regulating a process solution or the concentration of additives in a process solution, which influence the surface tension, particularly surfactants, in permanently operating industrial cleaning, coating, and rinsing installations, based on measuring the surface tension according to the bubble pressure method. Units detecting the surface tension or the concentration of a process additive in a process solution, processing and controlling a predefined internal program flow of the device, continuously monitoring the quality of a process solution, and triggering an external unit influencing the process are coordinated by means of an intelligent computer system which independently extracts and processes process data, uses the data for modifying the program flow thereof, exchanges the data with an external process control system, and influences the process.

    摘要: The present invention relates to a method for investigating the behavior of particles or droplets in a gas-vapor mixture inside a flow device, which is useful for studying cloud dynamical and microphysical processes. The invention allows adjustment and/or control of the thermodynamic system parameters based on the observed behavior of an internal standard with known properties, thus achieving a well-defined vapor concentration and saturation field inside the flow device. By injecting particles or droplets to be investigated into this well defined flow device, and measuring the size of the particles or droplets, the activation and growth or shrinking behavior of the particles or droplets may be determined using a mathematical model of the fluid, thermodynamic, and chemical conditions of the flow device.

    摘要: A method and apparatus therefor for depositing a flattened droplet on a partially absorbent surface comprising the steps of providing a narrow bore transfer tube having a proximal end and a distal end and containing a microvolume of liquid, the proximal end connected to a pneumatic system adapted for issuing an outgoing flow of displacement gas into the tube and drawing an incoming flow of displacement gas therefrom; and issuing an outgoing flow of displacement gas for slowly discharging substantially the entire microvolume of liquid as a droplet on the surface and controllably blowing one or more bubbles into the droplet towards the end of its discharge for flattening the droplet on the surface. A pump (31) comprising a housing (33) having a bore (34) with an internal peripheral surface (36), and a stationary annular sealing member (48) integrally formed therewith at a first end (37) of a pair of opposite ends (37 and 38); a slide rod (39) disposed in the bore and having an external peripheral surface (41) and a displaceable annular sealing member (49) integrally formed therewith; the sealing members sealing the peripheral surfaces to define a vented displacement volume (51) therebetween whose volume is proportional to an annular cross section area between the peripheral surfaces and a distance between the sealing members; and the slide rod being slidably reciprocable between first and second positions respectively toward and away from the stationary sealing member whereupon the displaceable sealing member moves to reduce the volume to issue an outgoing flow of displacement gas from the displacement volume on a downstroke of the slide rod from its second position to its first position and the displaceable sealing member moves to increase the volume to draw an incoming flow of displacement gas into the displacement volume on an upstroke of the slide rod from its first position to its position.

    摘要: The time profile of the output signal of an NOx measurement transducer arranged downstream of the NOx storage catalyst is used, during and after the regeneration phase, to derive a criterion as to whether the quantity of regeneration agent to be supplied to the NOx storage catalyst in a regeneration phase must be changed in order to achieve an optimum action of the exhaust-gas purification system. The output signal is picked off at the amperometric NOx measurement transducer at two electrodes. The measurement transducer exhibits the two-position behavior necessary for the method.

    摘要: In order to ensure optimum metering of a reagent to be metered into an exhaust gas during operation of a metering unit of a catalytic converter of a combustion system, in particular an internal combustion engine of a motor vehicle, in any operating state of the catalytic converter and/or in any operating state of the combustion system, a method and a device for operating a metering unit of a catalytic converter of a combustion system provide that, based on a steady-state value of the reagent quantity to be metered during a steady-state operating state of the catalytic converter and/or the combustion system, the quantity of the at least one reagent is determined and adjusted using at least one dynamic correction factor which is dependent on at least one of the performance characteristics of the catalytic converter and on at least one of the performance characteristics of the combustion system. The dynamic correction factor and/or a nitrogen oxide correction factor are obtained from a dynamic correction characteristics map or a nitrogen oxide correction characteristics map only as a function of performance characteristics of the internal combustion engine, in particular the engine speed and the injected fuel quantity, and of performance characteristics of the catalytic converter, preferably the nitrogen oxide emission and the temperature of the exhaust gas downstream from the catalytic converter.
