  • Patent number: 11098939
    Abstract: An ice maker for a domestic refrigeration appliance has an ice tray with at least one cavity for holding and freezing liquids to form a shaped ice element. An ejection unit ejects the shaped ice element from the cavity. A drive apparatus performs a relative rotational movement between the ice tray and the ejection unit to eject the shaped ice element from the cavity. The ice maker has a twisting apparatus that is coupled to the ice tray and that can be used to twist the ice tray around to release a frozen shaped ice element in the cavity. There is also described a domestic refrigeration appliance with the ice maker and a method for ejecting shaped ice elements from the ice tray.

  • Patent number: 10962445
    Abstract: The present teaching includes a speed control of a side shaft of a drive train connected to a dynamometer on a drive train test stand in which a torque (MFxi) caused by the longitudinal force (FXi) calculated in a simulation model is additionally transferred to the control unit, and from this a compensation torque (MKi) is calculated in the control unit as a function of the longitudinal force (FXi) caused by the torque (MFxi) and a deviation (AJi) between a moment of inertia (JBi) of the dynamometer and a moment of inertia (JRi) of the simulated vehicle wheel, the control unit calculates a torque (MREi,) from the setpoint speed (nBi,set) with a speed controller and a torque (MBi,soll) to be set with the dynamometer is calculated as the sum of the compensation torque (MKi) and the torque (MREi) calculated by the speed controller and set by the dynamometer.

  • Patent number: 10790642
    Abstract: The present invention relates to a contact device for transmitting electrical energy from a possibly movable, but preferably spatially fixed, bus bar to a tap-off device which may be movable along the bus bar or may be likewise spatially fixed. For this purpose, the sliding contact elements are configured in the form of sliding clip elements so that the connecting housing of the contact device is clippable onto the bus bar without using tools.
