Abstract: In an appliance for peeling fruit and vegetables, the appliance comprising an electric motor (1) driving a rotor (2) inside a cover (6), the axis of rotation (21) of the rotor being perpendicular to the surface to be peeled, and the rotor being loosely or pivotally mounted on the axis of rotation and being driven at a speed such that the tangential speed of the blades (16) carried by the rotor is at least equal to 7 meters per second.

Abstract: Peeler for a product (P), such as a fruit or vegetable, using a rotating tool moved in relation to the product so as to explore the surface of the latter and mark on it successive parallel turns, characterized in that the said tool is in the form of a vertical cutter (T) and comprises a part of revolution (1) of small diameter and a small number of teeth, whether cutting teeth or not, forming projections (2), this tool (T) being driven in rotation about its axis (AT) at a high speed and in such a direction (S) that the said projections (2) engage the skin of the product from below, starting from the adjacent turn already peeled.

Abstract: A continuously renewing separator with a rotating cylindrical wall of the type comprising a helicoidal winding with closely adjacent turns of an endless belt which is looped about itself so as to unwind slowly at one end and rewind at the other end while advancing axially at the same time as it is drawn into continuous rotation at a greater speed. The belt is disposed in a rotating first cage turning at the great speed and comprising on the one hand a device for supporting and guiding the cylindrical part with adjoining turns, progressive unwinding and rewinding guides located fixedly in said cage and a slow and continuous drive means for the belt in relation to said cage. The supporting and guiding device, as well as the drive means are constituted at the same time by a second cylindrical cage coaxial with the first cage and comprising equidistant bars which are integral with and project inside two continuous terminal drumheads.

Abstract: Continuous centrifugal filtering device for precipitation, washing or draining. The rotative cylindrical sleeve is constituted of a helical winding with continuous coils of a long strip mounted in a rotative case including cylindrical rollers engaging the exterior of the cylndrical sleeve, and driven in rotation at slow speed, all in the same direction. The strip forming the cylindrical sleeve is looped in an endless assembly by a return coil which extends from one extremity to the other of the helical winding so that the porous cylindrical sleeve thus formed advances slowly axially renewing itself constantly. The device can be used for making coffee.

Abstract: Automatic coffee maker comprises a rotatable chamber defined by upper and lower members which closely approach each other to define a narrow gap at their peripheral edges, one of which edges is flexible. Ground coffee is centrifugally driven toward said gap, which, in one position of the chamber is too narrow to pass the grounds, while permitting liquid to seep therethrough. The chamber may be moved to a second position in which the gap is wide enough to release the grounds.
