Abstract: A ceramic or composite blank for the purpose of attaching it to at least one magnet in the clamping chuck of a machine for material-removing processing, supporting a magnetic or magnetizable part on at least one of its two opposite sides.

Abstract: A tooth filling material of powder and liquid is described, essentially consisting of a mixture of the following ingredients: A) an organic, self-hardening component and B) an inorganic component that involves a curing reaction with the formation of crystals and expansion, C) water, with the characterizing property that, after mixing, the mixture remains plastically deformable in a processing time of 2 to 5 minutes and then hardens within 10 to 15 minutes.

Abstract: The invention pertains to a device for electrodepositing metallic, prosthetic, molded, dental components, whereby the device has a glass beaker for accommodating an electrolyte bath, a stirring system for moving the electrolyte bath, a heating system for heating the electrolyte bath, at least one anode and at least one cathode, as well as a unit for supplying electricity that is connected to at least one of the anodes and to at least one of the cathodes. Use is hereby made of a heating system that is formed from at least one infrared emitter whose main emission is in the 0.5 &mgr;m to 1000 &mgr;m range of wavelengths.

Abstract: A melting trough made of ceramic material is used for melting small amounts of metal by means of a flame including at least one trough channel which is not closed during operation. A thermosensor having a protective cover extends into the trough which is filled with melt during operation through an aperture in the wall of the trough. The aperture as well as the thermosensor are located below the level of the melt.
