  • Patent number: 10224785
    Abstract: A cooling system for a dynamoelectric machine comprising a cooling jacket for assembly on an outer circumference of a stator of the dynamoelectric machine, a housing for receiving the stator having the mounted cooling jacket such that a hollow chamber, which can be filled with a liquid cooling medium, remains between an outer wall of the cooling jacket and an inner wall of the housing, wherein an inlet opening for inlet of the cooling medium into an inlet region and an outlet opening for outlet of the cooling medium from an outlet region of the hollow chamber are arranged on the housing and a barrier element connected to the cooling jacket for spatial separation of the inlet region from the outlet region is provided. The efficiency of such a cooling system is improved in that the barrier element presses against the inner wall of the housing having increasing pressure difference of the cooling medium in the inlet and outlet region.

  • Publication number: 20180371346
    Abstract: Polymer pellets are formed using laminar gas flow within a downstream gas conduit, as may be implemented consistent with one or more embodiments herein. A gas channel directs gas to an outlet of a polymer extrusion mandrel via which a polymer melt is extruded. A downstream gas conduit extends away from the outlet of the polymer extrusion mandrel, and provides laminar gas flow along the polymer melt extending from the extrusion mandrel, and within the downstream gas conduit. Using this approach, laminar flow can be maintained along an initial portion of the polymer melt, and used to control the subsequent formation of pellets therefrom.

  • Patent number: 10077037
    Abstract: A hydraulic control device for at least one hydraulic aggregate of a brake system, and a brake booster control device, interacting therewith, for an electromechanical brake booster of the brake system. The hydraulic control device includes a first control electronics by which at least one motor target quantity that is to be realized by a motor of the electromechanical brake booster can be determined, taking into account a provided brake actuating strength quantity relating to a current actuation of a brake actuating element, and by which a specification signal corresponding to the at least one determined motor target quantity can be outputted to the brake booster control device. The brake booster control device has a second control electronics that, at least in a normal mode, outputs the control signal to the motor of the electromechanical brake booster, taking into account the specification signal outputted by the hydraulic control device.
