  • Patent number: 10260205
    Abstract: A road paver is provided with a drive, a bunker, a material conveying device, a screed comprising a tamping device and an electric heating device on the screed and/or on the tamping device, wherein a control unit is configured in such a manner that it determines, by means of a measurable electrical operating parameter of the electrical heating device on the screed and/or on the tamping device, the weight and/or the center of gravity and/or the width of the screed transversely to the working direction of the screed. A method for determining a width and/or a weight and/or a center of gravity of a screed of a road paver, comprising the steps: measuring an electrical variable of a heating device, in particular a heating power, a heating resistance or a power consumption of the heating device; calculating the weight and/or the center of gravity and/or the width of the screed transversely to the working direction of the screed by means of the electrical operating variable.

  • Publication number: 20030207057
    Abstract: A metered dose inhaler having part or all of its internal surfaces coated two or more times with a polymer comprising one or more fluorocarbon polymers, optionally in combination with one or more non-fluorocarbon polymers, containing an inhalation drug or a physiologically acceptable salt thereof, optionally an excipient and a fluorocarbon propellant. Also, a method for coating all or part of internal surfaces of a metered dose inhaler can comprising applying a first coat comprising a one or more fluorocarbon polymers to all or part of the internal the surfaces of a metered dose inhaler can. Subsequently, heating the first coat of fluorocarbon polymer and then applying a second coat comprising one or more fluorocarbon polymer on top of the first coat of fluorocarbon polymer. The two coats of fluorocarbon polymer are then heated to give a metered dose inhaler can that is more efficient in dispensing consistent doses of aerosol formulations.
