The invention concerns a method for simultaneously operating at least two tunnels on at least a network. It includes, at the intermediate node, a sequence comprising retrieving all the tunnel headers (step E8) and, if required, reassembling the original packet from its fragments (step E7), processing operations corresponding to one or more functions, performed on the original packet (step E3), optionally fragmenting once more the packet which have been processed (step E11) and restoring the headers of the tunnels (step E14).

The invention concerns a method for polymerising vinyl monomers and/or oligomers comprising at least a vinyl radical, which consists in mixing the vinyl monomer or the oligomer comprising at least a vinyl radical with: at least dioxygen supplying agent, at least a aldehyde representing for example between 1% and 15% of the weight of the mixture, at least an accelerator which may for example of consist in a metallic salt.

The inventive acoustic filter comprises two solid bodies (1, 2), at least one of which is piezoelectric. Said bodies are interconnected in such a way as to form a plane interface (3) between them, acoustic waves being generated by the piezoelectric body by means of an electrical field and being guided by the plane interface between the two solid bodies. The solid bodies are selected wish the objective of ensuring that the acoustic energy of said waves decreases exponentially in the two bodies in a perpendicular direction (Oy) to the interface, starting from the interface.

La vis selon l'invention comprend une tête (1) présentant à sa périphérie (4) des conformations destinées à coopérer avec un outil de vissage pour exercer sur la vis un couple de vissage et une portion sous-tête cylindrique (8) dont le diamètre est inférieur à celui de la tête (1) mais supérieur à celui de la tige filetée (7) de la vis, le raccord entre cette portion cylindrique (8) avec la périphérie (4) de la tête (1) et avec l'extrémité de la tige (7) s'effectuant grâce à des épaulements radiaux (R 1 , R 2 ).
摘要:
The invention concerns a recording and/or storage device comprising at least a camera (V1 to V4) mounted on the vehicle (20) and designed to deliver continuously a series of images and an electronic circuit (21) capable of transferring at every moment, into a buffer (23), the images delivered by the camera (V1 to V4) so that at every moment, said storage contains a sequence of images photographed by the camera for a predetermined time interval preceding said moment, and an impact sensor (25). The transfer of the data contained in the buffer (23), into a storage memory (24) for subsequent playback can be performed in response to a command carried out by the driver or optionally automatically following detection of an impact.
摘要:
The invention relates to a composite structure consisting of a relatively long filtration bar comprising, from the outside, an ultra-thin layer ( 26 ) that is selectively permeable to hydrogen and made from palladium or silver alloy. Said layer is disposed on a permeable, rigid, refractory substrate consisting of a more or less solid body ( 30 ) that is covered with an intermediary thin layer ( 28 ) having a relatively smooth surface. The body ( 30 ) and the intermediary layer ( 28 ) are made respectively by sintering with fine and ultra-fine Inconel grains. A rigid metallic axial structure ( 32 ) is embedded in the body ( 30 ). Veinlets ( 31 ), which are made in the body ( 30 ) through the destruction of thermo-destructible wires during sintering, increase the permeability of the substrate. The invention is particularly applicable to hydrogen-producing combustible gas processors.
摘要:
The invention concerns a method which consists in simultaneously producing in standing position, at least two or more furrows (83) and/or holes (84) for placing seeds and/or plants in the soil and an adaptable multipurpose device (1) for plantations designed therefor and capable of executing said operations according to said method. The device (1) consists of an interchangeable and/or extensible (2) or (33) support (2), fixed on an adjustable handle (11) and associated with at least a two or several removable implements (22), having appropriate shapes and dimensions, the support (2) or (33)/multiple tool (22) assembly, implementing a method which consists in simultaneously producing in standing position, at predetermined intervals, either several furrows (83) for receiving seeds or plants when the implements are curved wheels (29) or (58), or several holes (84) for receiving plants when said implements (22) are cones (23) forming planters, and from which furrows (83) and/or holes (84) it is possible, in accordance with the inventive methodology, by systematically transferring the device (1) at adaptable equidistance, from furrow to furrow or from hole to hole, to produce as many additional furrows (82) as there are rows to be traced and/or to dig as many holes (84) as there are plants to be planted, faster, without tiring and without bending, or having to relocate the string line (85) and piecemeal measuring of the spaces between said furrows (83) and holes (84). The invention and the adaptable multipurpose device (1) for manual use for producing furrows and/or holes for plantations cannot be dissociated, and in are particular but not exclusively designed for vegetable gardening and horticultural crops as well as for household gardening and vegetable gardens or for local authorities to create flower beds, parks and gardens and for greenhouse growing.

The invention concerns a device comprising two cylinder/piston pumping units (1, 2) whereof the rods are driven in translation by common motoring means (MC). The working chamber of said two pumping units (1, 2) is connected to a circuit comprising successively a conduit emerging into a rinsing liquid reserve (RL), two successive electromagnetic valves (EV1, EV2) and a pipe (TS) connected to pipetting means (AP), the larger working chamber being connected in the part of said circuit providing the junction between the electromagnetic valves (EV1, EV2) while the other working chamber is connected in the part of the circuit located between the second electromagnetic valve (EV2) and the pipetting means (AP).
摘要:
A method for transmitting information between a plurality of local units (Mi) connected to several electricity distribution networks comprises transmitting information on one of the distribution networks by a modulated carrier current at a carrier frequency spaced from the distributed current frequency, and transmitting the information from one network to the other through a coupling device (14) which maintains the galvanic insulation between the networks.
