  • Publication number: 20220318340
    Abstract: A method for determining a value of a variable quantity. A processing unit temporally consecutively receives multiple values of the variable quantity including respective associated detection points in time. Based on at least one of the multiple values and the respective associated detection points in time, the processing unit determines pieces of calculation information, which characterize a calculation rule used for determining a value of the variable quantity at a desired point in time. The pieces of calculation information are transferred from the processing unit together with at least one of the detection points in time to another processing unit, so that the calculation rule is determined there based on the received pieces of calculation information and the received detection points in time, and thus a value of the variable quantity may be determined at a desired point in time.

  • Publication number: 20220221678
    Abstract: An optical element held in a holder has a first optical surface which has no rotational symmetry with regard to its imaging axis. The holder has at least one reference element, which defines a position and/or orientation of the holder in a predefined coordinate system which compensates for a difference between an actual pose of the first optical surface and a target pose of the first optical surface in the holder at least in one degree of freedom. The reference element defines at least one specific azimuthal position of the holder. Also provided is a method for adjusting the holder of an optical element that has at least a first optical surface, which has no rotational symmetry with regard to its imaging axis, to a difference between an actual pose of the first optical surface and a target pose of the first optical surface in the holder.

    Abstract: The present invention is directed to a process for the production of graft copolymer compositions which are based on acrylonitrile-styrene-acrylate (ASA) or acrylonitrile- butadiene-styrene (ABS) graft copolymers. The graft copolymers compositions are obtained by emulsion polymerization and afterwards precipitation, dewatering, drying and optionally cooling of the dried graft copolymer powder, wherein the graft copolymer B powder obtained is mixed with an aeration gas, preferably air and/or nitrogen, wherein the bulk density of the graft copolymer B powder is equal or less than 98.5% of the bulk density of the non-aerated graft copolymer B, during the whole aeration step. The graft copolymer powders show higher powder flowability and less tendency of caking during storage, for example in a silo.
