Abstract: A low-pressure vessel cover includes a plate-shaped base for placing on a vessel edge of a low-pressure vessel, a first opening in the base, and an acoustic signaling device for detecting a boiling point of a liquid which is heated in the low-pressure vessel. The signaling device includes a note-sounding plate system, which has a note-sounding plate, a note-sounding plate opening, and a note-sounding tongue. The note-sounding plate system is arranged in a first flow channel which extends from the first opening in the base to a first outlet opening such that the note-sounding tongue is excited by out-flowing fluid and generates a signaling tone of at least 40 dB.

Abstract: The invention relates to a valve unit for a pressure vessel, the latter consisting of a receptacle and a lid which can be placed on said receptacle in such a way as to make it pressure-tight and said valve unit including: a safety function, pressure-relief function and pressure indicator function; adjustable indicator levels and pressure levels; an indicator pin (4) or indicator piston (10) which is supported against an indicator spring (7), can move in axial direction and bears on its portion becoming visible upon pressurization, due to its emergence from a valve housing (12), indicator rings, for example, for indicating the pressure inside the vessel; and comprising a valve body (5) which is movable in axial direction against the action of an exhaust steam spring (6) and, in the closed position, rests against a seal seat (19), lifting off from this, when a given pressure inside the vessel is exceeded, to uncover a pressure-relief aperture (20), in which case both the indicator spring (7) and the exhaust ste

Abstract: An electronic module for temperature-monitored preparation of food in a cooking vessel, having a base sensor for sensing the temperature of the base of a cooking vessel, and having a communications device for signal transmission of the sensed temperature to a means for controlling or regulating the heating capacity of the cooking point for heating the cooking vessel, where the base sensor has a sensor element, which can be guided into, and out of, a mount in the base of the cooking vessel and is secured in an articulated manner on a housing of the electronic module and is connected to the communications device.
