On amène une matière première en particules, un polysaccharide et de l'eau à une extrudeuse qui fonctionne dans des conditions de température et de pression telles que, lorsqu'il sort de la filière de l'extrudeuse, le produit extrudé prend une section transversale plus grande que celle de l'orifice de sortie de la filière.

In a distortion inspection apparatus of a glass plate, a light and dark contrast pattern is sensed by an image sensor through a glass plate. The number of bits corresponding to a light or dark portion is detected from bipolar image data which are divided into a plurality of bits along each of parallel scanning lines assumed upon a surface of the glass plate. Then, a distortion state of the surface...

The present invention relates to a binding for holding the rear part of a boot on a ski. This binding is characterised in that the elastic energising mechanism comprises a piston 7 pushed back towards the front against the rear face of a frontal bearing element 13 mounted so as to be movable longitudinally and itself pushed back against the rear edge 11c of the manual ski-removal lever 11, and the...

Automatic device for connecting a first processor (2) to a computer bus (6) on which information is transmitted in accordance with a bus protocol complying with a second processor (4) in the case where the said first processor is provided with an instruction set comprising a collection of indivisible instructions of read-modify-write type (LME), each indivisible instruction comprising at least one...

The fixation element comprises a support 2, and at least one anchoring stud 3 joined to the support. The stud has a blind hole 36, 37, 38 and longitudinal slots 39F delimiting anchoring lips 39L. Preferably, the hole is tapped in order to receive a screw which exerts a calibrated pressure against the bottom 38 of the hole in order to separate the lips and anchor them to the wall of a drill hole in...

Monoester griseolic acid derivatives of formula (I): (in which: R<1> and R<2> are the same or different and each represents a hydrogen atom, a hydroxy group or a protected hydroxy group; R<3> and R<4> each represents a hydrogen atom, or together represent an extra carbon-carbon bond between the two carbon atoms to which they are attached; one of R<5> and R<6> represents a hydrogen atom and ...

Hydrocracked, low pour lubricating oils of good stability are manufactured by passing a suitable hydrocarbon feed sequentially through a hydrocracking zone, a catalytic dewaxing zone, and a hydrotreating zone, all at high pressure and in that order, and with separation of hydrocrackate from recycle hydrogen prior to dewaxing. Only clean makeup hydrogen is fed to the dewaxer, passed through the hyd...

A puncturing device for insertion into the body, which has an ultrasonically coded displacement scale of gaseous inclusions regularly spaced along the length of the device. Owing to the acoustic reflectiveness of the gaseous inclusions, the precise location of the puncturing device can be directly and readily detected by an ultrasound visualization system. The acoustically reflective displacement ...

3-(Halogenovinyl- or propenyl-)-2,2-dimethyl cyclopropane-1-carboxylic acid esters, which are precursors of, or may themselves be, pyrethroid insecticides, are prepared by the reaction of certain halogenopentadienes with an alkyl diazoacetate in the presence of a catalyst which is a transition metal complex of certain chiral Schiff bases, which catalysts tend to increase the yield of preferred cis...

A new istamycin A derivative called di-N6', O3-demethylistamycin A exhibits a high antibacterial activity against various bacteria, particularly Pseudomonas aeruginosa.
