Abstract: A fuel supply circuit of an aircraft engine includes a centrifugal pump mechanically coupled with an engine shaft delivering mechanical power. The circuit further includes at least one electromagnetic pump including at least one stator delimiting an annular internal volume in which is present a rotor able to drive a fluid, a plurality of magnets annularly distributed on the rotor and at least a plurality of coils annularly distributed inside the stator face-to-face with the magnets. The rotor is connected to the engine shaft by a one-way clutching element.

Abstract: A turbomachine comprises a rotating spool comprising a drive shaft delivering mechanical power. The turbomachine comprises an electromagnetic pump mechanically decoupled from the drive shaft. The electromagnetic pump comprises at least one stator delimiting an annular internal volume in which is present a rotor able to drive a fluid, a plurality of magnets distributed annularly on the rotor and at least one plurality of coils distributed annularly inside the rotor. The coils of the plurality of coils face magnets along an axial direction.

Abstract: A method and device are provided for reducing electricity consumption associated with a communications line having a set of N carriers of predetermined power suitable for conveying information to a receiver device. The method is adapted to determine first and second groups, each having respectively at least one of the carriers of the set N; to determine a volume of information to be conveyed on the N carriers during a unit of time; and if the determined volume is less than a predetermined threshold, to allocate a power less than the predetermined power to the carriers of the second group, the power of the carriers of the first group being maintained.

Abstract: Microsurgery clamp, particularly a microincision capsulorhexis clamp, having a proximal handling portion or handle including two branches or arms interconnected at one of the ends thereof, so as to be suitable for being approached or separated elastically, and a distal clamping portion having two narrow and thin clamping blades connected to the distal ends of the handling branches and oriented laterally relative thereto. The distal end of each of the clamping blades being curved in a direction opposite to that of the handle, so as to form a clamping tip. The clamping blades are oriented in a direction or plane corresponding to the approaching or separation directions of the handling branches. The clamping blades are arranged above each other, relative to a vertical position of said handle, so that the approaching or separation movement of said handling branches results in the approaching or separation movement of said clamping tips, respectively.

Abstract: The invention relates to a method for producing a surgical micromanipulator tip including a proximal mounting base, at least a first elbow, and a distal manipulator finger. The elbow is connected to the mounting base and terminates at the free end of the tip. In addition, the mounting base includes at least one distal segment. The first elbow and the manipulator finger together form a tip portion. The tip portion is uniformly tapered by pointing.

Abstract: The invention relates to a method for producing disposable tweezer tips for ophthalmological microsurgery tweezers for cataract surgery, especially those with a grip portion in a single piece of plastic and two arms interconnected by one of the ends thereof in order to form the proximal portion of the tweezers. There is also a tweezer portion having metal tips inserted into the distal ends of the arms during the molding of the grip part. The tweezer tips with the grip teeth are cut out and shaped on a cutting press provided with suitable cutting tools from a metal strip or plate having a tensile strength coefficient of between 350 and 550 Rm N/mm2.

Abstract: The invention relates to a surgical forceps, in particular an opthalmologic microsurgical forceps. The invention includes a gripping part moulded in one piece from a plastic material. The gripping part has two arms connected to one another at one end thereof. There is a clamping part formed by metal tips inserted into the distal ends of the arms during the moulding of the gripping part. The distal part of the forceps is equipped with centering devices having a cylindrical finger solidly connected to one of the branches of the forceps and oriented towards the other branch. The centering devices also have a transfixing hole provided in the other branch opposite the finger. According to the invention, the centering devices are provided in the end portions of the plastic arms, in which the proximal portions of the metal tips are inserted.

Abstract: The invention discloses a method of transferring calls from a first station of a first telecommunications network (PSTN) including integrated call transfer means to a mobile station connected to a radio communications network. An auxiliary device is intended to automatically trigger a call transfer activation and/or deactivation control by transmitting predefined messages from the auxiliary device which have integrated network transfer means (PSTN) for their destination. The auxiliary device may advantageously be used in a charger of a mobile station and thus it includes detection means for detecting the presence of the mobile station for automatically triggering a call transfer when the station does not rest on its charger.

Abstract: The invention relates to a telephone comprising a keyboard which has keys to which various functions are assigned. According to the invention, the operation of certain keys is admitting of being blocked, and the function assigned to the non-blocked keys is admitting of being modified.A device is admitting of being adapted to said telephone to mask the blocked keys to the user. Advantageously, this device is a housing of a shock-resistant material.Applications: The invention permits of modifying and simplifying the man-machine interface of a telephone.Reference: FIG. 1.

Abstract: A display device is disclosed for displaying a character having a font of the "7-segment" type. The display includes segment drivers for activating/deactivating one or various icons from a set of icons formed each by one or various electrically connected segments. The set of icons includes six icons chosen so that all the characters of the 7-segment font, including numerals zero to nine, are restorable by selective activation/deactivation of the icons.

Abstract: An illuminated keyboard with keys capable of selectively passing through polarized light of different polarization directions. Keys are provided with two different labels. In a first mode a first label associated with a key is selected, and in a second mode a second label associated with the same key is selected. A first polarizing filter is provided, which filter is associated with the first label, for passing through the first label of polarized light emerging from a first source of plane-polarized light, and to filter polarized light emerging from a second source of plane-polarized light, the polarization directions of the two sources being perpendicular to each other. Similarly, a second polarizing filter is provided which is associated with the second label. The selection of the different labels associated with a key is performed by selectively energizing the first and the second source.
