  • Patent number: 12253168
    Abstract: A vehicle park lock actuator is arranged in a longitudinal axis and has a movable actuating element which is movable into a first position and a second position. A locking slotted guide, and a locking element is held displaceably perpendicular to the longitudinal axis and has a first surface and a second surface at a different distance from the longitudinal axis, and connected by a wedge surface with a gradient. The first surface is in operative contact with the locking element in the first position and a second surface is in operative contact with the locking element in the second position. At least the first surface and/or the second surface is inclined in relation to the wedge surface.

  • Patent number: 11679440
    Abstract: A method for producing one or more concave cut-outs on a main body, which is in particular substantially cylindrical, more particularly one or more grooves on a magnetic armature, a push rod, or a magnetic keeper plate, includes the following steps: providing a main body, which is in particular substantially cylindrical and has a first axis of rotation, rotating the cylindrical main body around the first axis of rotation in a first rotational direction by means of a lathe, and rotating a striking tool, which is provided with a number of fly cutters, around a second axis of rotation, which extends in parallel and offset in relation to the first axis of rotation in a second rotational direction, which is opposite to the first rotational direction, in such a way that the fly cutter engages in a material-removing manner in the main body to produce the cut-out.

  • Patent number: 7699561
    Abstract: A method for improving the recovery efficiency of storing fresh water into an aquifer, the storing includes injecting the fresh water and extracting the injected fresh water by a single water storage system that includes at least one well penetrating into the aquifer, the method includes: providing a plurality of screens, each screen being located alongside a wall of at least one well, and each screen respectively allowing a flow of fresh water between an associated storage zone in contact with the screen and the well on which the screen is located; controlling the flow of fresh water through each one of the plurality of screens according to parameters provided from a storage model of the aquifer, the storage model describing a behavior of each storage zone.

  • Publication number: 20080047326
    Abstract: A method for storing a liquid into a geological formation uses at least one well penetrating into the geological formation. The geological formation comprises at least one storage zone. A plurality of screens is provided, each screen being located alongside a wall of at least one well. Each screen respectively allows a flow of liquid between an associated storage zone in contact with the screen and the well on which the screen is located. The flow of liquid through each one of the plurality of screens is controlled according to parameters providing from a storage model of the geological formation. The storage model describing a behavior of each storage zone.
