  • Publication number: 20130197765
    Abstract: An electrical system of a vehicle includes at least one energy store, the vehicle having an internal combustion engine and electric machine mechanically coupled thereto, an actuatable accelerator pedal for predefining a torque to be output, an engine controller for injection of fuel, and an actuatable brake pedal, using which a controller is activated at least in a first partial range of its actuation, subject to first external operating conditions, so that recuperative power of the electric machine is generated at the same time that energy is fed into the electrical system. To increase the recuperation potential, the electric machine is switched to recuperative power by the controller in an operating phase in which a driver request is inferred due to actuations of the accelerator pedal, resulting in a braking power of the vehicle, the injection of the internal combustion engine being maintained due to second internal operating conditions.

  • Publication number: 20130168226
    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.

  • Patent number: 8408794
    Abstract: A linear ball bearing for longitudinally movable mounting of a shaft-like guide rail in a part surrounding the guide rail, which has a sleeve-like cage with recesses arranged one behind the other in the circumferential direction holding ball circuits which have at least one supporting section with supporting balls which are supported such that they can roll on the guide rail. The supporting balls are also supported such that they can roll on a raceway of a supporting race element inserted indirectly or directly into the cage. The supporting race element has at least one radial outer surface, arched outward at least in one direction, for contact against an inner surface of the part which surrounds the guide rail. The outer surface is formed by at least one web-like projection extending in the longitudinal direction of the supporting race element.

In this case, two of the impedance elements are connected in series in a main path and form a T configuration with a third component. In addition, a fourth component is connected in parallel with the main path of the circuit. By way of example, the components arranged in the main path are variable capacitances and the further components are inductances.

  • Publication number: 20130023398
    Abstract: The present invention relates to a centrifuge rotor, in particular a laboratory centrifuge rotor, including a rotor body, wherein the rotor body at least partially includes a porous metal or a porous metal alloy and an armoring located radially outside with respect to the rotation axis of said rotor body is provided. The centrifuge rotor allows centrifugation to be performed in a shorter time than previously and at a higher rotational speed. This results, inter alia, in higher RCA (relative centrifugal acceleration) values and thus in a very rapid separation of the constituents of the substances to be centrifuged.

  • Publication number: 20120280152
    Abstract: Exemplary embodiments are direct to a valve system for actuating the piston of a piston cylinder arrangement for a hydraulic or fluid device, and for actuating the piston cylinder arrangement for actuating the movable contact piece of a high-voltage circuit breaker. The system including a main control valve arrangement, having two 2/2-way valves used as main valves and which can be controlled by a pilot control valve arrangement. The main control valve arrangement directs a path for the high pressure fluid to the chamber above the piston and connects the chamber to a low-pressure tank for discharging the chamber above the piston. Two 2/2-way valves which form the pilot control valve arrangement are associated with the main control valve arrangement such that the 2/2-way valves direct or supply either a high-pressure control pressure or a low-pressure control pressure to the main control valve arrangement.

  • Patent number: 8283178
    Abstract: A process for removing hydrogen halide and water from hydrolyzates obtained by way of halogen-acid hydrolysis from vegetable biomasses. Two containers are connected to each other via a tube. Two flows are fed in at the inlet of the first container, one representing the hydrolyzates and the other a heat transfer medium; both flows are sprayed together in the first container, producing a homogeneous mixing of the two flows, including heat transfer, which subsequently results in complete evaporation of water and the hydrogen halide dissolved in the hydrolyzates. The evaporation produces a mixture of granular solid bodies and heat transfer medium droplets that is pulled from the first container into the second container through the connecting tube via a pressure gradient. The second container is configured as a cyclone or centrifugal force precipitator, and there is a separation of liquid and solid constituents from the gas.
