  • Pulsed electrolysis with reference to the open circuit voltage
    Patent number: 11242603
    Abstract: Various embodiments include an electrolysis method comprising: applying a pulsed voltage or a pulsed current between an anode and a cathode; repeatedly measuring a respective current OCP at the cathode in a zero-current state relative to a reference system; and controlling the pulsed voltage or the pulsed current so a working potential of the cathode in the current-carrying state with respect to the reference system has a defined progression relative to the respective current OCP. The defined progression includes a first phase at a cathodic level and a second phase at an anodic level.
    Type: Grant

  • Liquid cooling compositions
    Patent number: 10722434
    Abstract: Suggested are liquid cooling compositions, containing (a) L-Menthol, (b) D-Menthol, and (c) at least one further cooling agent, selected from the group consisting of isomenthol, menthyl acetate (L), menthyl acetate (D), menthyl acetate (iso), acetic acid menthyl lactate (iso) and acetic acid menthyl lactate (neo) with the proviso that in case that component (c) represents Isomenthol, the compositions do not contain any alkanediols.
