Abstract: A method for producing a metal plate having at least one embedded temperature sensor and to a metal plate produced by the method. The metal plate is produced from a plurality of layers or plate bodies, which are diffusion-connected to each other by thermal pretreatment and subsequent rolling. A sheathed thermocouple is rolled, as the temperature sensor, into the metal plate during the production of the metal plate, or a protective tube made of metal is rolled into the metal plate, into which protective tube a sheathed thermocouple can be inserted after the metal plate has been processed further to form a cooking vessel.

Abstract: A description is given of a process for producing a metal plate having at least one embedded heating element and of the metal plate produced by the process. The heating element is arranged between two plate bodies, and the heating element is embedded in the plate bodies by rolling with material displacement. The adjacent sides of the plate bodies have a layer of aluminum or an aluminum alloy. After a heat pre-treatment at the re-crystallization temperature of the aluminum or the aluminum alloy, the plate bodies are pressed against one another to bring about a reduction in thickness, with which the plate bodies form a diffusion bond with one another and are integrally bonded to one another over the entire surface area thereof to form the metal plate to be produced. The process produces a metal plate as a whole with better thermal conductivity and a broader spectrum of use.

Abstract: The invention relates to a cooking vessel comprising a base made of a multilayer material and a side wall, the said multilayer material comprising, in succession from the outside of the vessel to the inside of the vessel: an outer part, having a thickness eE, consisting of a layer of a ferromagnetic Nickel based alloy having a Curie temperature of between 30 and 350° C. and a thermal expansion coefficient of greater than or equal to 6.5.10?6 K?1, and a core, having a thickness ec, comprising at least one layer selected among aluminium, aluminium alloy and copper.
