  • Anti-corrosion treatment for conversion layers
    Patent number: 8435360
    Abstract: The invention relates to a method for producing a coating layer protecting against corrosion wherein a surface which is to be treated is brought into contact with an aqueous treatment solution containing chromium(III) ions and at least one phosphate compound, wherein the ratio of the molar concentration of the chromium(III) ions to the molar concentration of the at least one phosphate compound (calculated as orthophosphate) lies between 1:1.5 and 1:3. The method improves the corrosion protection of metallic, in particular, zinc-containing, surfaces provided with conversion layers. The decorative and functional properties of the surface are maintained or improved. Furthermore, the known problems resulting from the use of chromium(VI)-containing compounds or from post-treatments with polymer dispersions are avoided.

    Abstract: At least one characteristic, such as the mass/density and/or moisture content and/or dielectric constant, of a substance (such as the rod-like tobacco filler of a continuously advancing cigarette rod or a continuously advancing rod-like filler of filter material for tobacco smoke) is ascertained by an evaluating circuit receiving high-frequency signals from a resonator arrangement which receives microwave signals at least at two different frequencies from one or more microwave generators. The substance is caused to advance through a dielectric resonator of the resonator arrangement, and the high-frequency signals are influenced by the substance. For example, the circuit can compare first and second curves of high-frequency signals which respectively are and are n ot influenced by a selected substance; the curves can have sloping flanks and each of the two frequencies can be allocated to a sloping flank of a curve.

  • Method of and apparatus for ascertaining the density of a stream of fibrous material
    Patent number: 5762075
    Abstract: The density of a wrapped rod-like filler of tobacco or filter material for tobacco smoke is ascertained by causing successive increments of the filler to traverse beams of X-rays which, after having penetrated through small portions of the filler, impinge upon detectors forming a linear array and serving to generate (first) signals denoting the intensities of the respective beams. Such intensities are affected by the densities of the respective portions of the filler. The first signals are processed in a circuit together with one or more additional signals denoting the intensity or intensities of one or more beams which bypass the filler, and with one or more further signals furnished by one or more detectors which are shielded from the source of X-rays. The thus obtained (second) signal denotes the densities of successive increments of the filler and is used to correct the density of the filler, if and when necessary.
