Abstract: The invention relates to a charging device including a reversible AC/DC converter enabling power to be supplied to two outlets that have different voltages. Said charging device is particularly suitable for use as an on-board electric motor vehicle device. The device enables power to be supplied to both a traction battery, at a relatively high voltage, and apparatuses from the very low-voltage grid. Said device has a small overall size and low weight. The invention rests on a DC/DC converter (in the AC/DC converter) having multiple reversible outlets that includes a single transformer.

Abstract: The invention relates to packaging, e.g. an envelope or a parcel, that can be checked for tampering, which packaging includes a hermetically sealed body, the body being formed by folding a sheet of material that has been cut to a predefined shape. In order to track the object packaged in the packaging and in order to check the packaging for tampering, the tampering further includes an electronic component that can be interrogated remotely and that is formed by data storage means connected to an antenna. The antenna is formed by an antenna circuit which extends at least over the entire periphery of the inside surface of the sheet of material. Thus, any fraudulent opening of the packaging can be detected by the antenna circuit breaking, thereby making any transmission with the component of the packaging impossible.

Abstract: A new surface-active agent of the formula: ##STR1## wherein R and R' are hydrocarbon groups, M being a cation it is particularly suitable for the production of micro-emulsions in the presence of aqueous saline solutions.One important application thereof is in the assisted recovery of crude oil.

Abstract: Oil and water microemulsions having a high salt content and intended for assisted petroleum recovery are prepared from a concentrate containing:a mixture of at least three surfactants constituted respectively by a salt of an alkylsulphuric acid, a salt of an alkylaryl sulphonic acid and a salt of a carboxylic acid derivative selected from the group comprising sulphosuccinic acid and sulphosuccinamic acid,at least one cosurfactant constituted by a compound which is capable of forming hydrogen bonds with water.

Abstract: A defoaming apparatus comprising a column having three levels, a lower level, an intermediate level, and an upper level. The foam to be broken is injected into the lower level with mud. A shaft in the intermediate level serves as an aspirator. Air or another gas is injected into the shaft and the vacuum thus produced pulls the foam upwardly. The foam is discharged from the shaft against vanes located in the upper level where upon the foam is broken into gas which is discharged and liquid which is recovered. Sediment from the foam is drawn off at the bottom of the apparatus.
