  • Patent number: 10920013
    Abstract: Alkylene oxides are polymerized in a tubular reactor. The alkylene oxide is continuously introduced into the tubular reactor through multiple introduction points located along the length of the tubular reactor. Monomer flow rates are increased along the length of the reactor to maintain a nearly constant concentration of unreacted alkylene oxide.

  • Patent number: 10480184
    Abstract: Sound-permeable lining (1) for covering perforations (21) shaped in an acoustic plasterboard (2). The sound-permeable lining (1) comprises a first ply (12) of a fleece material and attached thereto a second ply (14) which is arranged in between of the first ply (12) and the acoustic plasterboard (2) to which the sound-permeable lining (1) is to be applied. The second ply (14) being of a foil material having a second opacity O2 and a plurality of through-holes (141) formed therein. The first ply (12) has a first opacity O1 so that the through-holes (141) formed in the second ply (14) are invisible through the first ply (12) and so that the applied sound-permeable lining (1) has an overall opacity O12 to allow for optically covering the perforations (21) shaped in the acoustic plasterboard (2) and an overall air flow resistivity Rs12 to allow for the penetration of air so that sound can propagate via the sound-permeable lining (1).

  • Publication number: 20190256653
    Abstract: Unsaturated polyether monols are removed from polyether polyols by reaction with a functionalized thiol compound or a polythiol compound. This process replaces the terminal unsaturation with a functional group, or else couples two or more of the monols to form a polyol. The functionality of the polyether polyol product is increased by the removal of the monols.

  • Patent number: 10188903
    Abstract: Embodiments relate to determining a speed of a multidimensional motion of an athlete in a global coordinate system based on multidimensional acceleration data from a multidimensional accelerometer placed at a movable limb of the athlete, the movable limb being at least one of translatory and rotatable, and the movable limb defining a local coordinate system. Based on the multidimensional acceleration data, at least one correction quantity may be determined taking into account a rotation of the local coordinate system relative to the global coordinate system during the multidimensional motion. The speed of the multidimensional motion may be determined based on an integration of the multidimensional acceleration data and in consideration of the at least one correction quantity.

  • Patent number: 10184026
    Abstract: Vinyl-functional alcohols are silylated by reaction with a hydrolysable silyl hydride compound. The starting alcohol is heated and then combined with the silyl hydride and catalyst and allowed to heat exothermically. Cooling is applied when the conversion of vinyl groups is between 90-99%. In some embodiments, specified amounts of water are present. The cooling regimen and control of water content reduces certain side reactions, leading to greater yields to desired product.
