Abstract: The cooking hob (1) has a support plate (2) made of glass or glass ceramic, a lower magnetic coupling member (5) rotatably arranged below the support plate (2), a drive motor (6) operatively connected for rotating the lower magnetic coupling member (5), and position changing means (33) for moving the lower magnetic coupling member (5) between an operative position, in which the lower magnetic coupling member (5) is close to the support plate (2) and magnetically transmits torque to an upper magnetic coupling member (54) connected to rotary blades (53) installed in a cooking vessel (50) located on the support plate (2), and an inoperative position, in which the lower magnetic coupling member (5) is far enough from the support plate (2) for not magnetically transmitting the torque.

Abstract: Appliance for squeezing citrus fruits with centrifugation of the product squeezed, composed of a milling cone (1) and a centrifuging bowl (2) provided with holes and/or slots (3) for filtering the juice or squeezed product which goes to a collecting container (4a, 4b), those cone (1) and bowl (2) are independent to each other, detachable and having independent rotation, being associated to different shafts (5 and 6) associated by respective drives (7 and 8) coupled to a single electric motor (9) or to several electric motors (10, 11) independent, cone (1) and centrifuging bowl (2) being driven at different speeds in same or opposite direction, and there exists a device for willingly annulling cone (1) or bowl (2) operation. The collecting bowl (4a, 4b) includes an external annular tank (17a, 17b) for collecting an excess of pulp thrown from bowl (2).
