Abstract: A potato peeling disc for peeling potatoes has a central opening formed by an inner contour of the potato peeling disc. A surface of the potato peeling disc comprises a plurality of teeth. The teeth have an orientation such that potatoes are peeled by the teeth by rotating the potato peeling disc in a first direction of rotation about a central axis which is coaxial with the central opening.

Abstract: A method for peeling potatoes with a food processor and a food processor which comprises for food preparation a detachable food preparation vessel, a heating element for heating a food in the food preparation vessel and a rotatable tool for mixing or chopping the food in the food preparation vessel. The method includes attaching a potato peeling disc having an abrasive structure on its surface from above to the tool which is located centrally at a bottom of the food preparation vessel to establish a manually releasable, rotationally coupled connection such that in operation the potato peeling disc rotates at the same rotational speed as the tool; addition of potatoes into the food preparation vessel from above onto the potato peeling disc; motorized rotation of the tool in a first direction of rotation and peeling of the potatoes with the potato peeling disc inside the food preparation vessel.

Abstract: A sound absorption element for means of transport, in particular for aircraft, comprising at least one sound absorption panel arranged on a base panel with the base panel comprising a multitude of recesses, in particular a hole grid or the like, for the transmission of sound. According to the invention, the sound absorption panels are each framed by a frame, wherein on the at least one frame at least in some sections a transition profile, in particular to prevent fatigue fractures due to stepwise changes of rigidity between the at least one frame and the base panel is arranged. Due to the base panel comprising a multitude of recesses, in particular comprising a hole grid, in connection with the sound absorption panels an air-permeable sound absorption element can be achieved.

Abstract: A sandwich element for a sound-absorbing inner cladding of transport means, such as aircraft fuselage cells, comprising a honeycomb-shaped core structure and cover layers applied to both sides of the core structure. At least one cover layer is constructed as permeable to air at least in sections and a covering is disposed at least in sections on at least one cover layer, wherein a sound absorption layer is disposed at least in sections in the area of at least one cover layer. A plurality of passages in the cover layers allow efficient transmission of the sound impinging on the sandwich element from outside as far as the sound absorption layer of the sandwich element.
