  • Patent number: 8863717
    Abstract: An intake device of an internal combustion engine has primary and secondary intake lines for aspirating primary and secondary combustion air, respectively. The primary intake line opens into a primary inlet chamber and the secondary intake line opens into a secondary inlet chamber of a filter housing. In comparison to the primary intake line, the secondary intake line has a configuration such that, in normal engine operation, a flow capacity of the secondary intake line, in comparison to a flow capacity of the primary intake line, is so minimal that secondary combustion air aspirated through the secondary intake line has a negligible effect on the performance of the internal combustion engine. When the primary intake line is closed, the flow capacity of the secondary intake line suffices to supply the internal combustion engine with a minimum combustion air mass flow required for operating the internal combustion engine.

  • Patent number: 8728192
    Abstract: A filter housing has first and second housing parts connected to each other to be openable and secured by a latching element. The latching element is connected to the first housing part by a moveable connection with a predetermined breaking point and is pivotable by the movable connection into the closed state. The latching element has two positioning elements and the housing parts have counter positioning elements. In the closed state, the counter positioning elements are axially arranged between the two positioning elements and the positioning elements form a stop for the counter positioning elements. The latching element has an element locking section locking at a housing locking section on the first or second housing part. The predetermined breaking point is subjected to mechanical stress such that the predetermined breaking point breaks upon locking or release of the latching element.

  • Publication number: 20140046610
    Abstract: A method for improving the usability of photovoltaic installations (PV installations) by taking account of shading information of adjacent PV installations for forecasting the power output by a relevant PV installation is provided. In particular, cloud movements and cloud shapes are taken into account. This improves the accuracy of the forecast. Here, it is advantageous that short-term forecasts in relation to e.g. the next 15 minutes are possible and a substitute energy source can be activated accordingly, in good time, prior to a dip in the power output by the PV installation. The invention can be used e.g. in the field of renewable energies, PV installations or smart grids.

  • Publication number: 20130153694
    Abstract: A method is disclosed for controlling a mill system having at least one mill, e.g., an ore mill or cement mill, wherein electrical power is drawn from a power network to rotate at least one mill body for comminuting a material fed to the at least one mill body. One or more control variables of the mill system are regulated such that the power drawn from the power network corresponds to a predetermined setpoint power draw-off for the mill system. The method may provide control power in the power network for compensating for fluctuations in energy generation due to increased use of regenerative energies. The method may be used, e.g., to regulate high energy mill systems, e.g., tube mills, SAG mills, or ball mills, such that even relatively large quantities can be made available as control power in the power network.

  • Publication number: 20130008985
    Abstract: The rotational speed of the drum of an ore mill may be controlled variably over time. By rotating the drum during a first time interval at high speed, especially hard or dense particles are broken up by tumbling. At the same time, the discharge characteristics of the mill are adversely affected. In a subsequent second time interval, the drum is rotated at a slower speed, and the material is discharged more effectively, whereas the tumbling movement inside the mill is not achieved. The combination of said different modes of operation within short time periods in continuous operation may improve both the comminution as a result of a tumbling motion of the material and also the discharge of the ground material. By regulating the rotational speed with different target values within short time windows, different requirements for the movement behavior of the material to be ground and for the discharge characteristics of the ground material can be simultaneously optimised.
