Abstract: An electrically powered knife has a handle with projecting removable knifeblades driven from a drive unit containing an electric motor, the drive unit being readily disconnectable from the handle so that this can be cleaned without risk of damage to the motor. A switch controlling motor operation is located in the drive unit but is operated from the handle by a mechanical link or a Bowden cable extending from a push button to an end surface of the handle to engage a switch member at an adjacent surface of the drive unit.

Abstract: An automatic coffee percolator with a fresh-water reservoir, a continuous-flow heater below the fresh-water reservoir, the heater including at its end a completely closing valve under control of a temperature sensor, and also comprising a percolator element with a filter, which is arranged below the continuous-flow heater, a receptacle being arranged underneath the percolator element. In such automatic coffee percolator hot water or vapor is not discharged into the fresh-water reservoir, and the water flowing through the continuous flow heater can be controlled within a narrow temperature range independently of the pressure of the supplied water.
