Abstract: An electronic safety device for automatically interrupting the supply of electric current to a heating resistor of an iron at the end of a predetermined interval of non-use, comprising a movable body adapted to control a position of contacts of an associated switch so that at least one opening-closing sequence of the switch contacts is obtained upon displacement of the movable body. Associated with the switch is a resistor bridge supplied with a rectified voltage E and comprising a first resistor R.sub.1 and a second resistor R.sub.2 in series with the switch contacts. A capacitor is connected to the terminals of resistor R.sub.2, a voltage V.sub.o being collected at the terminals of said resistor R.sub.1 and being applied to one input of a counter which is reset to zero each time voltage V.sub.o is higher than E/2, that is, upon closing of the contacts. The counter is connected to an input of a comparator for transmitting a voltage V.sub.1 when the counter attains a predetermined counting threshold.

Abstract: A first coating of enamel slip of a conventional type for aluminum is applied on the bottom face of a culinary vessel of aluminum or aluminum alloy, then heated in order to produce partial evaporation of water from the coating. Without allowing coating to cool, a second coating of abrasion-resistant enamel is applied on the first coating and reheated in order to produce complete evaporation of the volatile components. The two coatings are then immediately fired in order to sinter the enamels.

Abstract: A drawing recipient borne by a body is associated with heating means. A filtering recipient is also associated with heating means and in the operational position is raised and laterally off-set with respect to the drawing recipient. A spout serves as a spill-way from the bottom of the filtering recipient to the drawing recipient. The filtering recipient is pivotably mounted with respect to the body, between the aforesaid operational position in which it overhangs the body, and a fold-away position in which it is brought back over the drawing recipient.

Abstract: The culinary appliance for preparing "hamburgers" comprises a heating resistor, a hotplate which is mounted above the resistor and on which the portion of meat to be cooked is placed, a pressure member which is applied against the portion of meat and forms a meat-cooking enclosure in conjunction with the hotplate, a bread-heating enclosure for receiving at least one piece of bread, and a base for supporting the heating resistor, the hotplate and the pressure member. The meat-cooking enclosure and the bread-heating enclosure are juxtaposed and heated simultaneously by the resistor, at least one metallic wall being placed between the bread-heating enclosure and the resistor in order to limit the heating temperature within the bread enclosure to the value required for the piece of bread.

Abstract: A cover having a flat top surrounded by a side wall is fixed on the sole-plate of a steam iron by force-fitting a peripheral flange of the cover within a channel formed in the sole-plate. By making use of a pressure roller, one edge of the channel is upset and flattened in order to set the cover flange within the channel.

Abstract: The appliance for wax depilation especially of the face comprises a magazine for receiving a block of wax, a tubular duct extending between the magazine and a nozzle having an external opening located at the tip of the outer casing of the appliance. The nozzle is intended to be moved to a point at which it is held in close proximity to the user's skin. A heater adjacent to the duct melts the wax which is engaged within the duct. A carriage for receiving the block of wax within the appliance is intended to be pushed by hand towards the duct by means of an external thumb control button.

Abstract: The electronic circuit of a laundry iron comprises at least one heat-generating element such as a triac or a dropping resistor. The heat dissipator comprises a tubular metallic casing which contains the electronic circuit and is housed within the handle of the laundry iron. The internal cross-section of the handle is similar in shape to the external cross-section of the tubular casing and a thermal bond is provided between the casing and the handle.

Abstract: An electric resistance heating device including a body having a metal mass and a sheathed electric heating element for heating the mass is provided with a temperature sensing thermistor designed for electronic temperature regulation. The thermistor together with the leads thereof is housed in a shrunk thermoplastic, e.g., PTFE, sheath and is inserted into a cavity within the mass closely approaching the heating element sheath through an orifice closed by a metal sealing plug having substantially the same composition and thermal characteristics as the mass. The cavity and the face of the plug are shaped to closely correspond to the sheath containing the thermistor and leads and any air spaces existing between the sheath, the mass and plug are filled with a silicone putty, such as silastene. The sealing plug is force fit within the orifice or inset therein by plastic deformation of the metallic mass.

Abstract: The appliance comprises a mixing chamber within which a mechanical beater is rotatably mounted, an oil reservoir, a sliding separator placed beneath the oil reservoir and a mixing chamber placed beneath the separator. Oil is fed from the reservoir to the mixing chamber via a calibrated passage which opens into the mixing chamber in a suction zone created as a result of the centrifugal force produced by the mechanical beater.

Abstract: An electric steam iron is provided with an auxiliary water injection device to obtain an instantaneous surplus of steam. The point of auxiliary injection (6) is located directly above a boss (3) into which a resistor type heating element (2) is cast. The boss has a planar top surface which is sloped in a direction towards a main vaporization chamber (4). The thickness of the boss between the heating element and its top surface is reduced to effect a rapid vaporization of the injected water.

Abstract: The wrapper is made from a sheet of semi-rigid and foldable material such as paperboard and has two surfaces which are cut-out of the sheet. The two surfaces are applied respectively against the internal face and the external face of the bottom of the utensil. The surfaces are joined to each other by means of four tongues spaced at intervals around the lateral wall of the utensil. The tongues cover the free edge of the side wall and are applied against the internal and external faces of the wall.

Abstract: The device comprises a steam-escape duct (1) terminated by a valve-seat (3, 4). A shut-off surface (71, 72), realized in a cap (65) at the bottom of an axial cavity (8) slidably mounted on the duct (1), rests, in the service conditions, on the seat (3, 4). The cap (65) is weighted such that its center of gravity is located below the seat (3, 4). The axial cavity (8) is connected to the outside by two eccentric vents (70) causing the cap (65) to rotate by reaction of the steam which traverses them as soon as the cooking-pressure is reached.The device comprises an element (73) permanently attached to the cap (65) and manually displaceable between two positions each of which determines a different lifting pressure for the cap (65) in relation to the duct (1).Use for permitting easy adaptation of the cooking pressure to the kind of food.

Abstract: Microfiches to be destroyed by heat treatment are placed within a disposable tube fitted with a sealing plug, then baked to a sufficient temperature to cause melting and discarded. The apparatus comprises an electric heating resistor and a tubular heating jacket for receiving the disposable tube, the sealing plug being forcibly engaged in the tube by means of a cap which is screwed down by hand. All negative sheets and documents having a photosensitive surface such as microfiches are destroyed economically without any contaminating waste products.
