Abstract: The invention relates to a method and a device for generating Alfvén waves, in which ionizable material is provided that penetrates a magnetic field. In order to create such a method or a device in which material can be conveyed based on the Alfvén waves, the magnetic field consists of a primary magnetic field that is periodically deformed by at least one oscillating secondary magnetic field that is polarized in the opposite direction from the primary field such that Alfvén waves are created in the ionizable material located in said magnetic field. The Alfvén waves propagate at a speed that depends on the density of the material penetrating the magnetic field and the field intensity of the magnetic field. The field intensity of the magnetic field is greater than the kinetic energy of the material located in the magnetic field such that material is conveyed by means of the Alfvén waves.

Title: Fan-type grinding wheel
Inventor: OLAF SCHWEITZER
IPC: B24D/
Filed: 2007-05-15
Abstract: The grinding wheel has grinding plates that form a triangle with an outer corner (2), an inner corner and a rear corner (4) in a basic form. The grinding plates are arranged in uniform angular distances on an edge region of a supporting disc under formation of a grinding plates-packet (13) such that the outer corner limits a part of an outer edge (14) of the packet, and the rear corner runs leadingly from an inner edge (19) to the outer edge of the packet with respect to a rotary direction (16), where the grinding plates-material is concentrated in a radial outer region of the packet.
