  • L-carnitine amidase produced by a microorganism
    Patent number: 5238838
    Abstract: The microorganism DSM 6230 produces an enzyme, L-carnitine amidase. This microorganism and/or the enzyme which it produces can selectively hydrolyze L-carnitine amide and/or the L-component of DL-carnitine amide to L-carnitine.

  • Circuit arrangement for converting an analog AC voltage signal to a digital signal
    Patent number: 4524346
    Abstract: Analog AC to digital signal converter includes a sampling circuit which cyclically samples the analog AC signal to form analog sampling values, and an analog-digital converter for converting the analog sampling values to digital sampling values. A sign integrator integrates the sign of the digital sampling values, and a compensating voltage generator generates a compensating voltage in dependence upon the integration result. A combination circuit combines the compensating voltage with the analog sampling value from the sampling means and applies the combination result to the analog-digital converter. The circuit compensates any DC voltage component contained in the analog AC signal and avoids interferences resulting from such DC voltage component.
