摘要:
The invention relates to a device and a method for carrier current control of electrical appliances on an electrical power supply network (8) comprising a transmission of an identifier of a device according to the invention, characterized in that it comprises at least one wireless and contactless detector (4) sensitive to control signals and linked to a data processing unit (3), said unit being suitable for executing, on detection of a matching command, a process for matching the device with at least one other device comprising at least one step of emitting an identifier of a device, termed the slave device (2), and at least one step of recording by a device, termed the master device (1), of each identifier that the latter receives by carrier currents. The invention applies also to a network of at least two carrier current control devices each connected to an electrical appliance and to an electrical power supply network (8).

Automatic pool cleaners (APCs) and components thereof are detailed. The APCs may include tracks for movement, with the tracks having teethed internal surfaces. The APCs additionally may supply shift mechanisms for purposes of changing direction of their movement and incorporate bladed scrubbers and easily-opening bodies.

Treatment devices for fluid such as water are described. Principally (although not necessarily exclusively) designed for use as chlorinators, the devices may divert water flowing in conduits into the devices for treatment and subsequent return to the flow stream. A return tube of the device may be designed to create vortex action, using a pressure differential to evacuate treated water from the device back into the conduit.
摘要:
The invention relates to a device for cleaning a surface submerged in a liquid, comprising: a hollow body; guiding members (5, 6) defining at least one axle; a filtration chamber; at least one driving electric motor; and a control unit (4) configured to control each driving motor in at least one direction at a speed selected from: at least a first speed at which the device occupies a first attitude moving along a pre-determined first path; and at least a second faster speed at which the device occupies a second nose-up attitude moving along a second pre-determined path different from the first.

L'invention concerne un procédé et un dispositif de protection solaire d'une zone (2) de toiture (1), dans lesquels un écran (3) est : disposé au-dessus de la zone (2) pour l'occulter du Soleil en été, monté fixe, et disposé de sorte à former une ouverture équatoriale du côté de l'équateur terrestre, et une ouverture polaire du côté du pôle plus haute que l'ouverture équatoriale ; la forme, l'orientation et la position de l'écran (3) étant choisies pour que : moins d'un quart de la zone (2) soit éclairé par le Soleil au solstice d'été, au moins un quart de la zone (2) soit éclairé par le Soleil au solstice d'hiver. L'invention concerne également un dispositif d'éclairage zénithal comportant un tel dispositif.
摘要:
The invention concerns a glow plug comprising a heating rod (11), a plug body (13) having a receiving housing (14) of the heating rod, a mounting device (48) for mounting the heating rod, permitting axial translation movements of the heating rod relative to the plug body and ensuring impermeability between the heating rod and the plug body, a load sensing sleeve (17) which extends around the proximal portion (50) of the peripheral metal tube (59, 61) of the heating rod in the proximal zone (51) of the receiving housing, directly adjoining axially the mounting device (48) axially on the proximal side.
摘要:
The invention relates to a method for preparing a composition of metal oxide nanocrystals from at least one organometallic precursor in an aprotic solvent in the presence of at least one PEG ligand including a carbon chain having: at least one end functionalized by a coordinating group containing at least one heteroatom, and at least one [-OCH 2 CH 2 ] n group, such that it is soluble in both the aprotic solvent medium and in water. The invention also relates to the resulting water-compatible and organo-compatible composition of metal oxide nanocrystals.
