  • Publication number: 20020107015
    Abstract: A radio receiver (1) with a recording unit (5) is proposed that serves to record incoming radio signals, in particular traffic radio signals. The radio receiver (1) has a low-frequency amplifier (10), which is connected to the recording unit (5) and to which an audio playback unit (15) is connected. The recording unit (5) is connected to a speech device (20, 25), preferably a hands-free microphone (20) and/or a handset (25) of a telephone unit (30). An announcement text can be stored in memory in the recording unit (5) via the speech device (20, 25). The recording unit (5) outputs a stored announcement text after receiving a prompting signal.

  • Patent number: 6321998
    Abstract: In the process for the continuous dispersion of at least one fluid A constituting the disperse phase and at least one continuous phase constituting the enclosing phase of a fluid B, at least one fluid stream A and at least one fluid stream B are fed into a dispersion apparatus and come into contact therein in a dispersion chamber.

  • Patent number: 6299657
    Abstract: In the reaction process, at least two educts A, B are divided by a system, assigned to each of them, of slit-like microchannels 1a, 1b into spatially separate fluid lamellae, which then emerge into a common mixing and reaction space 4. The fluid lamellae here have a thickness <1,000 &mgr;m, preferably <100 &mgr;m, at a width thickness ratio of at least 10. It is essential here that educts A, B can emerge as thin fluid lamellae 6a, 6b into the mixing/reaction space 4, each fluid lamella 6a of an educt A being led into the mixing/reaction space 4 in the immediate vicinity of a fluid lamella 6b of another educt B. The adjacent fluid lamellae 6a, 6b then subsequently mix by diffusion and/or turbulence. As a result, the mixing operation is accelerated substantially compared with conventional reactors. In the case of rapid chemical reactions, the formation of undesirable by-products or secondary products is largely prevented in this manner.

  • Patent number: 6264900
    Abstract: A microstructures lamellae mixer comprising a guide component for supplying fluids to be mixed to a mixing chamber, the guide component being composed of a plurality of foils which are layered one above the other and into which microchannels are incorporated such that separate fluids supplied to the guide component are formed into spatially separated microstreams which then emerge adjacent to each other in a mixing chamber.

  • Patent number: 6187898
    Abstract: The invention relates to a method for carrying out polycondensation reactions, according to which the polycondensation of a monomeric starting material is carried out with external supply of heat in a reactor combination which has at least two stages and is composed of a pre-reactor and a high-viscosity reactor, where the low-molecular-weight elimination products produced are removed by evaporation. In the pre-reactor, the reaction product is concentrated to give a high-viscosity preliminary product. The high-viscosity preliminary product is then fed to the high-viscosity reactor, in which it reacts to completion with simultaneous introduction of thermal and mechanical energy and with a residence time of from 20 s to 60 min to give a polycondensation product.

  • Patent number: 6100319
    Abstract: The plasticity of ceramic compositions and dispersions can be improved by addition of at least one polymer (I) with recurring succinyl units. This effect can be reversed by addition of a setting accelerator (II); preferred setting accelerators are polymers (II) of the polyalkylenepolyamine type.

  • Patent number: 6082891
    Abstract: In a static micromixer a flow guide structure consisting of a stack of foils provided with passages formed into alternate foils so as to extend between a mixing chamber at one end of the flow guide structure and different admission chambers at the opposite end of the flow guide structure, the passages are curved so that they are all parallel at their exit ends adjacent the mixing chamber and, at their entrance ends, the flow guide structure has face areas which are inclined with respect to the exit end face of the flow guide structure at such an angle that the curved passages have all about the same length.

  • Patent number: 6054553
    Abstract: Polymers having recurring succinyl units are obtained by an improved process by reaction of A, an unsaturated C.sub.4 -dicarboxylic acid or a derivative thereof, with B, a nitrogen-donating compound, in a first reaction step to give a reaction mixture comprising at least one low molecular weight reaction product, and subsequent continuous feeding of the reaction mixture into a continuously operated reactor to give the polymer in a second reaction step. In a further embodiment the invention refers to polymers having recurring succinyl units prepared by reaction of an unsaturated C.sub.4 -dicarboxylic acid or a derivative thereof with a nitrogen-donating compound in a first reaction step and subsequent feeding of the reaction mixture, without intermediate isolation, into an optionally continuously operated reactor, with removal of water, and treatment of the reaction mixture at a temperature of 140 to 350.degree. C.

  • Patent number: 5660709
    Abstract: The invention concerns an electrochemical process for the production of mllic hydroxides and/or metallic-oxide hydroxides from metal ions and hydroxide ions, as well as a device for carrying out the process. The metallic hydroxide and/or metallic-oxide hydroxide is formed in a chamber K, bordered on the cathode side by a bipolar membrane, and the required hydroxide ions arise by means of a bipolar membrane, the anion-selective layer being arranged on the anode side. The metal ions are either fed into the chamber K or formed in the chamber K in the presence of an agent, present in the chamber K and at a pH>7, which complexes the metal ions. The device for implementation of the process exhibits a cylindrical head geometry, connected to a conical geometry.
