  • Patent number: 9704660
    Abstract: The disclosure relates to an electrical switching device, which switches stroke-dependently, with extended switching hysteresis, including a switching element with a contact lever, the switching element cooperating with an actuating element movably guided in a holding device. The actuating element has a step-shaped portion for actuating the contact lever of the switching element and the actuating element has an opening in which an engagement element designed as a bolt or a pin engages when a switching action is initiated. The opening provided in the actuating element is formed as an elongated hole, in which the engagement element engages in order to achieve a switching stroke and a defined hysteresis is thus set depending on the design of the elongated hole.

  • Publication number: 20170163025
    Abstract: A method for controlling a multi-phase electric machine, whose phase terminals in an active bridge rectifier are respectively connected, via controllable first current valves, to a first DC voltage terminal and via second current valves to a second DC voltage terminal. The method includes switching on the first current valves when an output voltage between the first DC voltage terminal and the second DC voltage terminal has exceeded an upper threshold value at an exceedance point in time, and shutting off the first current valves again only once the output voltage has subsequently fallen below a lower threshold value at a shortfall point in time. The first current valves are shut off again after the shortfall point in time individually, and each only when a respective indication value, which characterizes a current flow in the phase terminal associated with the respective current valve, exhibits a predetermined property.

  • Patent number: 9620302
    Abstract: A storage module for a hydraulic stored-energy spring mechanism for operating a high-voltage switch, for example a high-voltage circuit breaker, having a spring element which acts to store energy and having a fluid for transmitting the energy of the spring element, by a moving storage piston, to a piston rod for operating the high-voltage switch, wherein the storage piston projects into the housing which is filled with fluid and the housing forms a pressurized storage reservoir for the fluid. The pressurized storage reservoir is connected to a hydraulic system of the stored-energy spring mechanism by at least one channel element which projects into the pressurized storage reservoir and a pressurized channel which is connected to the channel element. The storage piston closes a subregion of the channel element starting from a specific piston stroke “s”.

  • Publication number: 20160211740
    Abstract: A rectifier module for an active bridge rectifier having two switching elements, connected in series between two end terminals, and between which a center tap is formed, and a control circuit including a monitoring unit, a synchronization unit, and a control unit, the monitoring unit detecting a measuring voltage and outputting a request signal when the measuring voltage exceeds an upper threshold value. The synchronization unit outputs a synchronization signal to a synchronization terminal as long as the monitoring unit outputs the request signal, and otherwise to monitor the synchronization terminal for a synchronization signal. The control unit switches one of the two switching elements into a conductive state at least in sections during an activation period of time, when the monitoring unit outputs the request signal and/or when the synchronization signal is detected and is optionally recognized as valid by the monitoring.

  • Patent number: 9254451
    Abstract: The invention relates to a method and a device with the aid of which hydrogen halide and water are removed from biomass hydrolyzates containing halogen acid. The core of the invention is an evacuated container (B1), which is continuously supplied with a heat-transfer medium and which is completely filled with the heat-transfer medium in a part. In said evaporation chamber, the biomass hydrolyzate is likewise continuously introduced. In the container (B1), heat is transferred from the heat-transfer medium to the hydrolyzate, wherein hydrogen halide and water are continuously evaporated. The remaining hydrolyzate particles are continuously discharged with the cooled heat-transfer medium and continuously removed by means of the heat-transfer medium and continuously separated from said heat-transfer medium. The invention described can also be used to treat other mixtures or solutions for the purpose of evaporation.

  • Publication number: 20150275320
    Abstract: The invention relates to the hydrolytic breakdown of plant biomasses via hydrohalic acids, preferably so-called hydrochloric acid. Ligneous biomasses were preferably hydrolyzed in the past because other types of biomasses, for instance straw, are only able to be filled into the reactors with a very low density and they tend towards compacting in the course of the process. The invention solves this problem with two modifications. First of all, pelletizable biomasses are completely or partially loaded in the form of pellets and a heavily increasing filling density is achieved because of that. Secondly, the hydrolysis reactors are tilted, preferably arranged between 30° and 60°, and compacting is prevented. The economic effectiveness of both modifications is to be determined in practical tests for every pelletizable biomass. It is possible that one of the two modifications can be omitted.
