  • Publication number: 20170233276
    Abstract: A method for the treatment of organic waste, the method comprising alternating steps of anaerobic digestion and aerobic composting conducted in a single reactor vessel, wherein at or about the completion of the anaerobic digestion step at least a portion of any free draining fluid from the reactor vessel is directed for reuse in subsequent anaerobic digestion steps, and solids remaining in the reactor vessel from the anaerobic digestion step are subjected to a dewatering step from which a liquid is obtained that is ultimately also directed, at least in part, for reuse in subsequent anaerobic digestion steps. A method for the management of biology in a batch process, wherein the batch process is an anaerobic digestion process, is also described.

  • Patent number: 9273406
    Abstract: An electrolytic cell, a method for manufacturing the cell, and a method of operating same. The electrolytic cell has at least two bipolar plates, at least one fluid inflow and outflow, as well as at least one laminated core arranged between the at least two bipolar plates. The laminated core is constructed from laminations which are stacked one on top of the other. At least two laminations have recesses which are designed to extend through the entire thickness of the respective lamination. The at least two laminations are arranged one on top of the other in such a way that recesses in adjacent laminations overlap partially, but not completely, as a result of which ducts, which are continuous in the direction of the plane of the lamination, are formed.

  • Publication number: 20120032633
    Abstract: A converter that feeds an electric drive in an electric vehicle is used to transmit energy to the vehicle without contact using resonant operation for inductive transmission of energy. The leakage inductance of the transformer is resonantly adjusted by a serial capacitor. The load current is then switched at zero-crossing.

  • Patent number: 8036009
    Abstract: Power is supplied to excitation windings in order to generate magnetic fields, preferably for activating superconducting coils. An AC transformer is used, and triggering of the coil is performed via a rectifier having little power loss. Preferably, a two-way rectifier using a freewheeling circuit is utilized in the associate device, thus preventing losses when power is supplied and especially when the power is discharged.

  • Publication number: 20100264563
    Abstract: The invention relates to a potting method and a device (100) for potting an excitation circuit that is arranged inside a rotor body. Said excitation circuit has a circuit board (102, 103) having contacts (103, 103?) on the edge of said circuit board (102, 103), the contacts (103, 103?) being arranged in a tolerance zone (109) around a cylindrical peripheral surface (110) that is concentric to the rotor body. The excitation circuit is located inside a potting zone (101) which is sealed in a liquid-tight manner by a toroidal elastic ring (111) in such a manner that surfaces of the contacts (103, 103?) lying within the tolerance zone (109) are at the same time in contact with the toroidal elastic ring (112).
