Abstract: The invention relates to a sectored distributor (112) for a turbomachine, including two coaxial platforms mutually connected by radial blades, the inner platform (130) being connected to an annular partition (138) for suspending an annular mounting (140) carrying elements (136) made of material subject to abrasion, this mounting sliding circumferentially on the partition and comprising a means engaging with means corresponding to the inner periphery of the partition to ensure radial restraint of the mounting on this partition.

Abstract: The present invention relates to a radar device for maritime surveillance, intended to be installed on a vehicle moving at very high altitude, generally on a satellite. The invention consists more precisely in a partial synthetic aperture radar with a low repetition frequency, making it possible to provide quality maritime surveillance and guaranteeing good performance in terms of target detection probability and ability to process vast maritime expanses.

Abstract: The invention relates to a method for separating a chrominance signal from a composite video baseband signal. In order to improve the separation, it is proposed that the composite video baseband signal is filtered sequentially in any order by means of spatial comb filter means in horizontal and vertical direction and by means of field comb filter means in vertical direction and temporally to obtain said chrominance signal. Thereby, the advantages of a spatial and a temporal filtering at different vertical frequencies can be combined. The invention relates equally to a chrominance-luminance separator comprising filter means for realizing the proposed method.

Abstract: The invention concerns a sensor for direct measurement of electromagnetic power, comprising a guiding structure (2) for bringing the power, a dissipative charge (3) and a thermometer. The invention is characterized in that the charge (3) and the thermometer are formed by a single element.

Abstract: An extruder with two distinct food processing sections. The food-subtances are transproted in opposing directions, The device and the process have many advantages as, for example, a reduced friction within the extruder, reduced abrasion of the extruder and the gear-box, and reduced material requirement with respect to the propelling device.

Abstract: The invention concerns a novel method for preparing tetrakis(pentafluorophenyl)borate derivatives of general formula MB(C6F5)4, M being selected among Na+, Li+, or K+, wherein: (a) a C6F5X solution, X being selected among H, Cl, Br or I, in anhydrous butylic ether is contacted with an alkyllithium, the mol ratio of C6F5X/alkyllithium being 1 to 1.1, and the alkyl radical, linear or branched comprising 1 to 10 carbon atoms; (b) the resulting product is contacted with previously non-dissolved BR3, R, identical or different being selected among a chlorine atom, a fluorine atom, a bromine atom, an alkoxy radical comprising between 1 and 4 carbon atoms.

Abstract: A protector device for a danger zone of the machine includes two parallel slides 10 disposed along two sides of this danger zone and two normally open switches 11, 11a connected in series in the electrical supply of at least one motor of the machine. One of these switches is disposed adjacent one end of one of the slides 10 while the other 11a is disposed adjacent the opposite end of one of the slides 10. It also comprises a protector element 8 sliding in the slides and whose length is such that in service position, this protector element 8 actuates the control members of the two switches 11, 1a to close them.

Abstract: The invention concerns a novel method for preparing non-toxic resins crosslinkable under radiation in the presence of an initiator system. Said resins are prepared from compositions of an organic and/or silicon type comprising monomers, oligomers and/or polymers with organofunctional groups, and are cross-linked in the presence of an initiator system consisting of an onium salt with low toxicity whereof the cationic structure is [(CH(CH3)2—C6H4—)—I—(—R1)]+(I).

Abstract: A non-reusable prefilled syringe for a single administration of a drug solution. The syringe has a plunger for expelling the solution which is detachably fitted with an elastomeric cap. The syringe allows for a pre-vein test but is not adapted for reuse. A method of use for subcutaneous injection of mini-doses of the drug solution.
