Abstract: Transport and conservation packaging is made from a blank sheet of material such as cardboard or corrugated cardboard. The packaging can be used for the transport of fresh food such as fish or meat, either alone or with the addition of ice. The packaging includes a bottom and relatively hermetic side walls, to withstand exudates and/or melting ice and to improve retention, possibly channeling evacuation. The packaging further includes a lid adapted to the base.

Abstract: A document with a cover having a first cover part, a second cover part, at least one internal page located between the two cover parts when the document is closed, a radiofrequency microcontroller, an antenna electrically connected to the radiofrequency microcontroller, and an electromagnetic shield capable of disrupting, at least partially, the wireless communication with the radiofrequency microcontroller when the document is closed and not disrupting the wireless communication when the document is opened. The electromagnetic shield is a wire grid. The wire mesh distance between each two adjacent wires of the wire grid is smaller than a radio-frequency wavelength used for communicating with the radiofrequency microcontroller, and is at least 0.1 millimeters and at most 40 millimeters.

Abstract: A document which includes a cover, one or more internal pages, a radiofrequency microcontroller, an antenna electrically connected to the radiofrequency microcontroller, an electromagnetic shield capable of partially disrupting wireless communication with the radiofrequency microcontroller when the document is closed, and not disrupting the wireless communication when the document is opened is described. The electromagnetic shield included in the document is implemented using metal, conductive plastic, conductive ink or magnetic ink.

Abstract: A process for placing elements of a self-stiffened panel of preimpregnated composite. The panel includes a base skin and a plurality of U-shaped stiffeners, with an interfacing structure including a nail and a nail-head. The process includes draping plies to form the base skin; placing and shaping at least one reinforcing ply on a set of punches; forming half-nails; placing a half-nail on the sides of each punch covered by the reinforcing ply; positioning the punches side by side in inverted U-positions; placing the nail-heads; compacting the set of punches; turning the punches 180 degrees; positioning the set of punches on the base skin; and withdrawing the set of U-shaped punches.

Abstract: A device for communicating with a portable data medium using at least a power signal (AL) supplied by an electric energy source (4), a control signal (SC1) and a data transmission signal (I/O), comprises an interrupter (5) for interrupting the power signal (AL) to the medium from the source if the portable data medium does not cooperate with the device (1), means (8) for storing electric energy received from the source and for supplying the power signal to the medium when the source does not supply power and a data processor (3) arranged to ensure transmission of the power, control and data transmission signals (AL, SC1, I/O) to the medium according to a predetermined sequencing, as well as for detecting the interruption of the power signal (AL) from the source, then for triggering the interruption of the control and data transmission signals (SC1, I/O) according to the predetermined sequencing during the supply of the power signal from the energy storage mean.

Abstract: A coupler for managing communication between a portable data medium and a data exchange device. The coupler includes bistable control circuitry (25) input-activated by at least two control signals (DTR, RTS) delivered by the data exchange device in one of two first and second predetermined input sequences, and arranged to output at least one power supply signal (VCC) and a data medium reset signal (RST) in a predetermined output sequence, such that the portable data medium is activated only when one specific input sequence of the two input sequences is received.

Abstract: The reactor is traversed by a central tube with an essentially radial circulation of the gases or other fluids. Said cylindrical part of the solids bed is surmounted by a substantially hemispherical reaction zone permeable to said gases or other fluids. The hemispherical part of the reactive zone is comprised between two substantially hemispherical caps one of which surmounts the central tube and the other bounds the upper periphery of this zone with the pressure drop undergone by the gases or other fluids passing through the hemispherical zone being greater than that undergone by the gases or other fluids passing through the cylindrical zone and therefore the perforations of the hemispherical part of the central tube are calculated to compensate for this difference and equalize the flow of gases or other fluids in the whole of the solids mass.
