This process comprises the steps of positioning a nitrosonium-conducting solid electrolyte between two porous electrodes, acting upon one of the two electrodes with the NO-containing fluid medium, and measuring a voltage difference between the two electrodes as an indication of the NO-concentration in the NO-containing fluid medium.

Abstract: A multipole electric motor having a plurality of pole laminations (8-11) guided from ends of coils (4, 5) to a permanent magnet (13) of a rotor (14), the pole laminations (8-11) are firstly produced as a coherent sheet-metal part, and is partially injection-coated with a plastic. Subsequently, the pole laminations (8-11) are separated from one another by means of a laser beam, for example. This renders the mounting of the pole laminations (8-11) particularly simple.

Abstract: Polyether esters are employed for the adhesive bonding of textiles since they are resistant to washing and dry cleaning. The polyether esters of the prior art have the disadvantage that they often exhibit poor adhesion with critical outer materials such as, for example, silk. By means of the polyether esters according to the invention, it is possible to bond sensitive textiles effectively at very low temperatures.

Abstract: A combination instrument having a front frame (12), a transparent cover glass (16), display systems (2) and/or operating elements mounted in the combination instrument, a circuit board (6) arranged behind them and bearing electronic components, the display systems and/or operating elements contacting the circuit board, and having a rear closure cover (13) for the combination instrument. Such a combination instrument is particularly easy to construct and mount and can thus be produced at favorable cost when it has a system support (1) developed as supporting structural part provided with recesses for the positioning and holding of the display systems and/or operating elements. The circuit board is connected to the system support. The system support thus represents the supporting element of the combination instrument around which all other parts of the combination instrument are grouped.

Abstract: A dial arrangement is formed of plastically deformable material, in particular sheet metal, for a combination instrument. It has at least two individual dials which are connected to each other, each being provided with an imprint. In order to permit a curving, i.e. an arching of the array of dials provided with the imprint while the individual dials are connected to each other without impairing the appearance of the individual dials, the connection in each case of adjacent individual dials is effected by at least one web, the web being arranged outside the center connecting line of the individual dials. The web in question can thus plastically deform upon the curving of the dial arrangement so that the dial center points and the respective imprints, and thus the appearance of the dial arrangement, are retained.

The combination instrument comprises a computer unit with microcomputers (36) and/or use-specific integrated circuits which are arranged, for protection against electromagnetic disturbances, within a housing (31) which is impervious to high frequencies.

Abstract: The process for manufacturing materials, in the form of sheets, foils or webs, comprised of chemically, mechanically and/or electrochemically roughened and anodically oxidized aluminum or an aluminum alloy, which process is performed with two hydrophilizing post-treatment steps. In post-treatment step (a) a supported aluminum oxide layer is treated with an aqueous alkali metal silicate solution which optionally contains alkaline earth metal ions, and in step (b) the aluminum oxide layer is separately treated with an aqueous solution containing at least one organic polymer comprised of vinylphosphonic acid and/or vinylmethylphosphinic acid monomers, such as polyvinylphosphonic acid. Treatment of the aluminum oxide layer is accomplished by means of immersion and/or electrochemically. Materials prepared by this process are particularly useful as supports for offset printing plates, showing an improved resistance to alkali and a reduced tendency to adsorb dyestuff.
