摘要:
A method for sending data by inductive coupling includes: extracting an antenna signal from an antenna circuit, extracting from the antenna signal a first periodic signal, producing a second periodic signal by way of a synchronous oscillator, placing the oscillator in a free oscillation mode and applying to the antenna circuit the second periodic signal, modifying the impedance of the antenna circuit, restoring the amplitude of the antenna signal, then resynchronizing the oscillator on the first periodic signal.

The invention relates to a heat-exchanger for an air-conditioning circuit that includes a first pipe (110) defining a path for a flow of fluid, the first pipe being spirally wound about a so-called exchanger axis (A). According to the invention, the heat exchanger (9) further includes at least one second pipe (120a, 120b) defining a path for a flow of a second fluid, said second pipe being provided against a surface of the first pipe (110) and spirally wound together with said first pipe (110) about said axis (A). The invention can be used in air-conditioning circuits operating with a super-critical coolant, in particular carbon dioxide (CO2).

Method and its associated device for the regulated injection of liquid carbon dioxide (CO2L) into a liquid (L) under pressure inside a chamber. The liquid carbon dioxide (CO2L) is, according to this method, injected at a fixed flow rate, in stepped mode, under the protection of a stream of gas (when injection is stopped).

The present invention relates to a method for continuously preparing mineral particles by means of the thermolysis of mineral precursors in an aqueous medium, comprising contacting: a reactive flow, including mineral precursors at a temperature lower than the conversion temperature thereof; and a coolant flow that is countercurrent to said reactive flow and contains water at a temperature that is sufficient to bring the precursors to a temperature higher than the conversion temperature thereof, the mixture flow that results from said reactive flow and said coolant flow then being conveyed into a tubular reactor, inside of which particles are formed by gradually converting the precursors, and where the reactive flow and the coolant flow are placed in contact with each other inside a mixing chamber, inside of which the reactive flow and the coolant flow are fed by supply pipes having outlet cross-sections that are smaller than the maximum cross-section of said mixing chamber. The invention also relates to a device for implementing said method.
摘要:
A device for conveying objects having a neck along a given direction having at least one pressure chamber capable of projecting an air flow on the objects along the conveying direction, and a support rail oriented along the conveying direction. The device includes transport shuttles fixed to the neck of the objects and cooperating with the support rail.

Polish applying and buffing glove (1) comprising at least two parts joined together detachably, namely a polish applying part (2) comprising a backing film (4) to which is affixed a pad (5) impregnated with polish and covered by a peel-off seal (6); and a buffing part (3) shaped like a glove and comprising a bag film (7) to which a buffing pad (8) is affixed.
摘要:
A route switching apparatus for conveying articles, including a plurality of lines suitable for conveying the articles along respective separate paths and a body having a polygonal cross-section and pivotable about a longitudinal axis. The body is positioned along the plurality of lines between an entry and an exit of the lines. The body has a plurality of lateral faces with transfer lines formed on respective lateral faces. The transfer lines communicate with respective lines of the plurality of lines between the entry and the exit. The body is pivotable such that the transfer lines can communicate with different respective lines so that the articles moving along one of the separate paths can transfer to another of the separate paths.
