Abstract: An attachment for monitoring a nut of a screw connection for crack formation, deformation, and/or breakage includes a socket portion which is attached to the outer circumference of the nut and has a conductor which is interrupted in the case of a deformation, crack, or breakage of the nut. The conductor is embedded in at least one material. The attachment is produced by injection molding with the conductor embedded within the socket portion. The monitoring attachment is particularly useful for operating a shutoff device for a wind generator in the event of failure of a nut which secures a turbine blade to the generator hub.

Abstract: A method for cleaning the cooking space of a cooking appliance with a pan including adding a cleaning agent to the cooking space and if necessary, after this agent has been allowed to work for a certain period of time, a liquid jet is introduced under high pressure from the a spray head of a cleaning device through the at least one spray nozzle, which rotates around an axis perpendicular to the rotational axis of the spray head rotating around this axis. The liquid jet consists exclusively of water and which swirls and splashes the cleaning agent, and if necessary, after this splashed agent has been allowed to work for a further certain period of time, removes the residues mechanically from the bottom, the walls, and the inside surface of the lid, and wherein said residues are then carried away together with the washing solution out of the cooking space via the drain.

Abstract: An apparatus and related method for operating a cooking appliance comprising a convection oven, a hot-air steamer, or a convection steamer, which includes a cooking chamber which can be closed by a door, a heating device, at least one steam injection device, at least one flow-generating device such as a blower, at least one temperature sensor, which detects the temperature in the cooking chamber, and an electronic appliance control unit with memory, in which cooking programs comprising the cooking sequences for specific food products are stored. Based on the time extending from a starting to a target temperature value, it is determined on the basis of the detected temperature curve in the cooking chamber whether and possibly to what extent it will take extra time to reach the target temperature. On this basis the appliance control unit calculates a cooking time extension, by which the cooking program step is extended.

Abstract: A cooking apparatus has a cooking chamber (10). The vapors created in the cooking chamber (10) are removed with a vapor outlet channel (31). A vapor condensation device (40) brings the vapors into contact with cooling liquid. The vapor condensation device (40) has a container (41), in which a liquid bath (42) is located. The vapor outlet channel (31) carries the vapors out of the cooking chamber (10) into the container (41) of the vapor condensation device (40). There, the vapors are brought into contact with the liquid from the liquid bath (42) and thereby partially condensed. Furthermore, a device drain (36) is provided.
