The invention relates to a longitudinal flexible heating mat. The inventive mat comprises a thin conductive metal strip (3) which is intended to be supplied with electric current at the ends (C, D) thereof and which is trapped between two flexible, insulating sheets (1, 1'). The mat is characterised in that: (i) the conductive strip comprises at least two elements (3a, 3b) which extend from one of the longitudinal ends (A) of the mat to the other longitudinal end (B) of same, (ii) the first ends (C, D) of the aforementioned elements are intended to be connected to respective electric power terminals, and (iii) the second ends (D, E) of said elements are free and intended to be connected to one another using connection means (7). The invention also relates to a method of producing one such mat.

The invention relates to a device which is used for the sterilisation of objects (19), in particular medical or surgical instruments. The inventive device is of the type that can create a gaseous plasma from a gas flow which is subjected to en electric field. According to the invention, the resulting post-discharge flow is brought into contact with the surface of the objects to be treated. The device is characterised in that the gas flow comprises exclusively nitrogen. Moreover, the device comprises means for heating the aforementioned objects, which can heat said objects to a temperature of at least 60 °C during treatment. The invention also relates to a method of using the device.

La présente invention concerne un abri du type constitué par au moins un élément de toiture polygonal (9) maintenu en position par une extrémité d'un bras (3) sensiblement horizontal dont l'autre extrémité est maintenue par un poteau vertical (1). Cet abri est caractérisé en ce que le bras (3) est lié au poteau (1) par des moyens de liaison (19,22,23) aptes à permettre un ajustement du bras (3) à la fois dans le sens vertical et dans le sens horizontal.
摘要:
The invention concerns an apparatus for shaping a flexible web (2). Said apparatus is characterized in that it comprises, between an entry roller (5) and a forming roller (3), a regulating module (7) provided with a starting roller (13) designed to control the movement and the speed of the web upstream of the shaping roller (3) and at least one mobile guide element (9) designed to exert, at least on one buffer loop (8) of the web (2) formed between said rollers (5, 3), a positive guiding thereof, in accordance with a law of displacement which is a function of the length of the buffer loop (8) in operation.
摘要:
The invention concerns a method for fractionating cooking oil, in particular frying oil, using a solvent with supercritical pressure. The method is characterised in that it comprises steps which consist in: contacting, in a mixer, the cooking oil with the solvent with supercritical pressure; separating the resulting mixture into two phases in a decanter, namely a light phase and a heavy phase; decompressing the light phase and the heavy phase so as to recuperate the solvent, and the treated oil and the treatment residues respectively.

The invention relates to a packer for a wellbore, comprising a central tubular element (7) covered by a deformable peripheral sleeve (5). Fluid is injected inside the tubular element under pressure in order to form said sleeve (5) and to apply it to the walls of the wellbore (3). The inventive device is characterized in that the deformable sleeve (5) is made out of metal and the inner wall of the sleeve (5) comprises at least one annular chamber (17) that extends over at least one part of the surface of the sleeve (5) and communicates with the inside of the packer via an orifice (19), whereby said chamber (17) is filled with a material that is non-miscible with respect to the wellbore fluid prior to the injection of said fluid under pressure.
摘要:
The invention concerns a method for obtaining solid particles from at least a water soluble product, characterised in that it comprises steps which consist in: forming a solution of said product in an aqueous phase, producing an emulsion, or a micro-emulsion, consisting of said aqueous mixture and a polar organic phase, contacting said emulsion, or said micro-emulsion, with a fluid at supercritical pressure, or a liquefied gas, so that the latter extracts the organic phase and the water, thereby precipitating the formed solid particles of the water soluble product, and collecting the resulting formed particles.
摘要:
The invention concerns a running device for a trailer type machine and in particular a pick-up, arranged at each end thereof. Said device is characterised in that it comprises at least a front wheel (43) and a rear wheel (37) whereof the axles are made integral with at least a frame member (31, 33) linked to the machine body (5) which is mounted rotating relative to the body (5) thereof about an axis (xx', 23) parallel to that of the wheels (37, 43).
