  • Patent number: 6753027
    Abstract: In a method of controlling a cooking process, at least two temperature values are picked up by a cooking process sensor which is adapted to be stuck at least partly into food to be cooked. Specific parameters of cooking food and/or cooking utensils are determined via the thermo kinetics of the temperature values registered, and the specific cooking food and/or cooking utensil parameters determined are utilized for controlling the cooking process. The invention likewise relates to a cooking process sensor for use with the method according to the invention.

  • Patent number: 6618824
    Abstract: An object code expansion program inserts new instructions and data between preexisting instructions and date of an object code file; offsets are modified to reflect new positions of the preexisting instructions and data. For each item of preexisting object code (instructions or data), the following steps are performed: making a new code block comprising any desired new instructions and the item, and storing it as new object code; tracking the location of the item and the new code block within the new object code; and tracking items that contain inter-item offsets. Then, each inter-item offset is updated using the new location of the item or new code block, as required. Finally, offsets in symbol tables and relocation structures are updated with the new location of the item.

  • Patent number: 6510782
    Abstract: A system for electronically monitoring scaling in an apparatus for heating and/or evaporating a liquid, comprising a container for at least temporarily receiving the liquid. The container comprises a liquid inlet, a liquid outlet and/or a vapor outlet and a heating element for evaporating liquid from the container. An evaluation unit is connected to at least one liquid level indicator and at least one flowmeter. A value relating to a desired filling volume of the container can be inputted into the evaluation unit and/or can be stored therein. The desired filling volume can be compared to a nominal liquid level in the evaluation system when water is constantly added by the flow meter, whereby the nominal liquid level is detected by the liquid level indicator, or to a nominal filled-in quantity detected by the flowmeter when the liquid flow indicator regulates the level of the filled-in liquid.

  • Patent number: 6318245
    Abstract: A cooking device has a cooking chamber, a ventilation device in the form of a ventilating fan wheel or the like and a heating device plus a catalyst. Air from the cooking chamber, including greasy vapors, odor particles, and/or hydrocarbons, can be directed in a finely-atomized form onto the catalyst by the ventilation device. The catalyst purifies the air directed thereon and releases energy in the form of heat during purification, which heat can be distributed inside the cooking chamber by the ventilation device.
