Abstract: The present disclosure relates to a method of determining an offset between a detector and a point on a motor, the movement of the point on the motor being impeded in at least one direction. In particular, this disclosure relates to a method of determining a commutation offset for an encoder that works in conjunction with a synchronous motor. The commutation offset is an offset between the detector and the north pole of a permanent magnet within the motor. The method comprises setting a test value for the offset, causing a displacement of the detector based on the test value and measuring that displacement. The method further comprises repeatedly increasing the test value, and causing and measuring a displacement for each so increased test value until it is determined that the test value has crossed a threshold.

Abstract: Liquid aspirator for drawing off and sucking up liquids, having a drawing-off lip, having a suction device for sucking up the liquid into a separating space in the housing of the liquid aspirator, having an exhaust-air channel, which is subjected to a negative suction pressure and is intended for leading the air out of the separating space, having a separating device, which is arranged in the separating space and separates the liquid from the water, and having a tank for accommodating the liquid. Complex guidance of the liquid/air stream is avoided in that the housing has a hollow chamber which forms the separating space and the tank, and into which the intake channel opens and from which the exhaust-air channel is guided out of the housing; wherein the hollow chamber contains a motor-driven rotor with a rotating impact surface, and the intake channel is designed such that the air/liquid stream is directed for radial direction reversal and acceleration onto the impact surface.

Abstract: The invention relates to a vessel cover for vessels in the form of cooking vessels or household vessels, comprising a cover (1), which is formed from a plurality of individual segments (2), which can be placed on the vessel edge, wherein the individual segments (2) are supported relative to one another so as to be rotatable about an axis of rotation at different heights, so that they can be fanned out a screen-like manner for the purpose of forming the cover (1), which at least partially covers the vessel, and can be rotated one on top of the other so as to form a stack in an inoperative position. The known covers have the disadvantage that they require a comparatively large amount of seepage space and/or that they can be attached to a steaming vessel only with the risk of being burnt.
