Abstract: The retractable winder comprises a support for winding the power cord of an electric flat-iron and two members for retaining the turns of the power cord. The support consists of a series of arms projecting from one face of a plate which constitutes the first retaining member. The second retaining member is constituted by the rear face of the flat-iron casing and provided with guide holes in which the cord-supporting arms are slidably engaged. An elastic traction member consisting of a rubber ring is mounted between the cord-supporting arms and provides a resilient connection between the flat-iron casing and the retaining plate.

Abstract: The opposite ends of a metal bar placed between a weighing platform and a base plate are rigidly fixed respectively to the platform and base plate. The metal bar carries flexure-sensitive strain gages and torsion-sensitive strain gages for cancelling the torsional stresses detected by the gages. Two pairs of flexure-sensitive strain gages are mounted on one face of the bar and aligned along the bar axis X--X'. The gages of each pair are connected in opposition of sign in a Wheatstone bridge circuit and an electric signal which is proportional to the force applied on the weighing platform is measured at the bridge terminals.

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.

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.
