Abstract: A wrinkle removing device comprises, inside a holding body and a sole under the body, a heating resistor for heating the sole, thermostat for temperature controlling the sole in a predetermined control cycle, a motor for producing vibrations and an electrical circuit. The electrical circuit includes the heating resistor, the thermostat and the motor, and is supplied with alternating current to power the heating resistor and the motor, in each case during at least one half-wave of the alternating current throughout the control cycle. With this device, an action of gentle massage of the face is combined with an action of sliding of the heated sole over the face, without producing disagreable variations in the speed of the vibration motor.

Abstract: The invention discloses a speed variator for an AC motor included preferably in a food processing apparatus. The variator comprises a controllable switching member, such as a triac, and an RC circuit for regulating the motor speed to a predetermined speed. A current compensating circuit is provided, connected across the terminals of capacitors in the regulating circuit and to a terminal of the variator for compensating a current increase to maintain the predetermined motor speed regardless of the fluctuations of the load torque on the motor during motor operation.
