The microcontroller includes a generator-programmer which controls at time intervals the emission of a signal to activate the additional control circuit which forces the receptor to assume its non-conducting state, and which analyzes the corresponding instantaneous state of a node of the detector in such a manner as to prevent the control center from directing the control circuit if its instantaneous state is different from the inactive state.

Abstract: A distribution chamber (12) of an electric steam iron comprises two compartments separated in part by a partition (24) whose upper edge (20) is in sealed contact with the cover (13). A first of those compartments (26) is connected to the inlet orifice (14) of the reservoir (15) and through it passes the valve (10) of a first water injection device (11). A second of these compartments (28) communicates with the first compartment (26) through at least one throat (30) and constitutes a water reserve when the iron is used with the sole in a vertical plane. There is immersed, through the cover (13), the opening (27) of a second water injection device (21) for the second compartment (26).

Abstract: Apparatus for thawing and reheating a deep-frozen food preparation by microwave and infrared radiation comprises a housing enclosing a heating chamber which is delimited by a tubular wall. The chamber is subjected to microwave radiation from two inlets as well as infrared radiation. The inlets of microwave radiation are arranged in two opposed regions of the tubular wall situated on either side of the central region where the food product is positioned, and the infrared heating elements comprise at least two lamps extending axially of the tubular wall and arranged on either side of the central region in two opposed regions distinct from those of the wave guide openings. A heating process performed using this apparatus involves simultaneously producing continuous microwave radiation by alternately feeding two generators branched in anti-parallel, and continuous infrared radiation, throughout a thawing and reheating cycle.
