  • Patent number: 12287316
    Abstract: The present invention relates to a water sampling immersion probe (50) for continuously filtering a water sample from wastewater (14). The water sampling immersion probe (50) includes a distal coarse filter (60) with a porosity of 0.1 to 1.0 mm, a proximal fine filter (70) arranged downstream of the coarse filter (60) and having a porosity of less than 5.0 ?m, and a sample suction opening (74) arranged downstream of the fine filter (70). The coarse filter (60) is arranged to not contact the fine filter (70).

  • Publication number: 20110306799
    Abstract: A method for the targeted execution of a reaction taking place alongside several competing chemical reactions is described, wherein the speeds of the competing reactions are set by the selection of the reaction conditions in such a way that the desired main reaction is not adversely affected. The invention further describes a new method for the oxidation of primary or secondary alcohols into aldehydes or ketones in the presence of dimethyl sulfoxide, a carboxylic acid anhydride or halogenide, and an amine in an organic solvent, in a continuous processing system (Moffatt-Swern oxidation).

  • Patent number: 6607655
    Abstract: Reactor for carrying out electrochemical reactions with an electrode and a counter-electrode are known, whereby the electrodes are separated form one another by a capillary gap. Such reactors do not comprise a homogeneous flow rate distribution in the capillary gap which can thus lead to a reduction of selectivity and of local temperature increases. In addition, high ohmic resistance requires the use of conducting salts. The aim of the invention is to provide a reactor in which the voltage drop in the electrolyte is minimized and which can be better optimized over a short resistance time distribution. To this end, the capillary gap comprises at least one channel as a reaction chamber having a height less than or equal to 200 &mgr;m. According to the inventive method, the volume flow of the educt current is measured such that the flow of the educt current is laminar over the length of the channel having a height less than or equal to 200 &mgr;m.

  • Patent number: 6587073
    Abstract: A method for the processing of a frequency signal especially for utilization in the evaluation of a distance measurement by means of pulsed electromagnetic waves or of frequency-modulated continuous waves on the basis of the radar principle. The frequency signal is divided into at least two frequency ranges corresponding to two main components of the frequency signal, the frequency signal in each of the two frequency ranges is then subjected to a separate Fourier transform, the Fourier transform applied to the frequency signal in the first frequency range resulting in a corresponding first complex time signal and the Fourier transform applied to the frequency signal in the other frequency range resulting in a second complex time signal. The second time signal is complex-divided by the first time signal which produces a third time signal, and the third time signal is then subjected to a Fourier transfer, the result being a processed frequency signal.
