  • Publication number: 20230121953
    Abstract: Apparatuses and methods for regulating a system rail voltage of a battery charger is described. An integrated circuit can be configured to detect a condition that requires an activation of a trickle charge mode of a battery charger. The integrated circuit can, in response to the detection, set a reference voltage to an intermediate voltage level. The reference voltage can control a system rail voltage of the battery charger, and the intermediate voltage level can be greater than a minimum of the system rail voltage. The integrated circuit can reduce the reference voltage from the intermediate voltage level to the minimum system rail voltage to regulate the system rail voltage at a predefined rate.

  • Patent number: 9314781
    Abstract: The present invention discloses a catalyst for paraffin isomerization, as well as a preparation method and use thereof. The catalyst comprises a TON molecular sieve modified by rare earth, an inorganic refractory oxide modified by zirconium oxide and a noble metal of group VIII. The weight ratio of the TON molecular sieve modified by rare earth to the inorganic refractory oxides modified by zirconium oxide is 10:90 to 90:10, and the content of the metal of group VIII is 0.1 to 10 wt % based on the metal. When used in the process of isomerization dewaxing of various raw materials containing paraffins, the catalyst can not only decrease the solidifying points of raw oil containing paraffins, but also increase the yield of liquid products. Particularly, when used in the process of isomerization dewaxing of lubricating oil distillates, the catalyst is advantageous in producing base oil for lubricating oil with a high a higher yield, a lower pour point (solidifying point) and a higher viscosity index.
