  • Publication number: 20170179976
    Abstract: A circuit and a method for converting an analog signal to a digital value representation is disclosed. In one aspect, the circuit includes an incremental sigma-delta analog-to-digital converter (ADC). The circuit further includes a first input line for providing a primary analog signal representing a sensor measurement to the incremental sigma-delta ADC. The circuit further includes a second input line for providing a secondary analog signal to the incremental sigma-delta ADC. The incremental sigma-delta ADC receives the primary and secondary analog signals during a first period (TADC1) and a second period (TADC2), respectively. The circuit further includes a filter configured to weight the digital values in a sequence of digital values output by the incremental sigma-delta ADC, and to output a single digital value representing the sensor measurement.

  • Publication number: 20120085151
    Abstract: The present invention relates to a method for automatically determining the relative solution viscosity and/or the melt volume flow rate of a polymer, during a phase of the process for producing the polymer, where the polymer is in a solution with 10 to 20% by weight of the polymer in an organic solvent. The method includes continuously removing a substream of the polymer solution from a component of the process for producing the polymer, wherein the polymer solution is essentially free from inorganic salts; removing a sample having a volume of from 1 to 10 ?l from the substream; introducing the sample into a gel permeation chromatography apparatus and determining the gel permeation chromatography data for the polymer; and automatically determining the relative solution viscosity and/or the melt volume flow rate of the polymer from the data obtained from the gel permeation chromatogram, on the basis of calibration relationships.

  • Publication number: 20050043443
    Abstract: A thermoplastic glass fibers reinforced molding composition that exhibits improved mechanical properties and resistance to hydrolysis is disclosed. The composition contains at least one thermoplastic polymer, sized glass fibers, and optional conventional additives and auxiliary substances. The sizing agent that is substantially free of emulsifiers not bound to the resin contains (a) at least one epoxide-functional, oligomeric resin, having epoxide group content of 0.15 to 0.75 mole per 100 g of resin, average functionality of at least 2.3 epoxide groups per molecule, (b) at least one epoxide curing agents, and (c) at least one silane coupling agent.

  • Publication number: 20040012121
    Abstract: A process for making a fiber reinforced molded article is disclosed. The process entails (i) melting a thermoplastic resin (ii) introducing and homogeneously distributing at least one fiber strands to the molten resin to form a mixture of fibers and molten resin and (iii) molding the article by injection or by compression molding, and (iv) solidifying the article. The process is characterized in that where the fiber strands have a fiber length of 2 to 25 mm and in that the molded article contains fibers the mean length of which is at least 400 &mgr;m. Lastly the process is characterized in that no cooling or solidifying take place between steps (ii) and (iii).
