摘要： A control circuit comprising a thyristor and a feedback circuit formed by an inductance and a generator for producing electrical energy in response to a luminous event. The feedback circuit controls the conducting or cut-off state of the thyristor by the fact that a trigger-gate of the thyristor is connected to a terminal of the generator having a polarity cutting off the thyristor when the generator is illuminated. The thyristor is switched on in response to an energy stored in the inductance, which energy is caused by a sudden discontinuity of the luminous event.

摘要： An electric flat-iron safety device includes a magnet pivotally supported in a flat-iron and arranged to actuate a first magnetically operated switch only when the flat-iron is in a horizontal ironing position and to actuate a second magnetically operated switch only when the flat-iron as tilted to a vertical rest position. Should the flat-iron remain motionless in the horizontal ironing position for a first predetermined time interval shorter than the time necessary for the flat-iron to reach its normal operating temperature, closure of the first switch by the magnet causes a resettable dual interval timing circuit to interrupt the power supply to the flat-iron. If the flat-iron remains motionless in the vertical tilted rest position for a second predetermined time for a interval longer than the time necessary for the flat-iron to reach its normal operating temperature, closure of the second switch by the magnet causes the dual interval timing circuit to interrupt the power supply. The dual interval timing the first or second switch opens in response to pivotal movement of the magnet prior to expiration of the first or second time interval.

摘要： A method of detecting the release of dye from laundry in a washing machine despite the presence of dirt in the washing water. During a washing operation, a radiation flux including an infrared flux part (.phi..sub.I) and a visible flux part (.phi..sub.V) is passed through the wash water in which it is subject to absorption and diffusion. The flux parts .phi..sub.I and .phi..sub.V are compared during the entire washing program and the ratio of .phi..sub.V and .phi..sub.I is determined. The release of dye is signalled by a substantial variation of said ratio. The signal may be used for actuating an alarm device and/or controlling the washing program.

摘要： A microwave oven includes a microwave source and a defrost detector arranged in the oven cavity in the proximity of a frozen product to be processed, the absorption of microwave energy being distributed between the detector and the product and causing their temperature to rise, the temperature variation of the detector being measured by a measuring element producing a corresponding electrical signal. The oven also includes a computing control device which determines completion of defrosting of the product by computing the values at successive instants of the second derivative of such signal as a function of time. The computing control device controls the oven at the end of the defrosting cycle, which is when the value of such second derivative falls below a predetermined value.

摘要： A device for contolling the charging of rechargeable batteries comprises two temperature sensors deposited on a flexible thin thermally and electrically insulating sheet. The thin sheet is disposed around the rechargeable battery so that one of the sensors determines the temperature of the battery and the other sensor determines the ambient temperature. A charge stopping device stops the charging of the battery when the difference between the temperatures determined by the two sensors has reached a predetermined value. The sensors consist of resistors applied by silk screen printing and disposed in a Wheatstone bridge arrangement.
